What are the reasons for the high oil temperature in the high tank of the heat-conducting oil boiler diesel burner?

The thermal oil boiler diesel burner is a new type of high efficiency, energy saving and energy A special industrial boiler diesel burner that provides high-temperature heat energy. It uses heat transfer oil as the heat carrier. The heat carrier is circulated through the hot oil pump to transfer the heat to the heating equipment. So what are the general reasons for the high oil temperature in the high tank of the thermal oil boiler diesel burner? Below we dare to explain briefly. Why is the high-level tank installed in the thermal oil boiler diesel burner? In the liquid-phase boiler diesel burner, the high-level tank is an indispensable facility. It is located at the highest position of the heating device system to ensure the liquid level status during normal operation. Its main functions: 1. Accommodate the increase of heat transfer oil due to expansion, stabilize the pressure of heat transfer oil in the system, to ensure the safe operation of the system in the liquid phase, and normal circulation; 2. Add light components of the newly added oil to the system The gaseous substances generated by separating and remaining in the system with a small amount of water and low boiling substances vaporized at high temperature are evacuated; 3. Inject oil into the system or supplement the oil loss of heat transfer oil caused by evaporation and operation; 4. In the event of a sudden power failure or other emergency, close the valve of the heating equipment and open the valve of the upper tank to allow the cold oil in the upper tank to replace the hot oil in the furnace, which can protect the heating equipment and ensure that the oil film does not exceed the temperature 5. Isolate the direct contact between the air and the high-temperature heat-conducting oil to ensure that the heat-conducting oil will not be oxidized due to high temperature and extend the service life of the heat-conducting oil; Sixth, add a nitrogen sealing device here as needed. Why control the oil temperature of the high-level tank? The high temperature of the high-level tank causes consequences; the heat transfer oil reacts with oxygen to make the system weakly acidic (increased acid value). The light components of the heat transfer oil volatilize-increase the replenishment amount and increase the high components and reduce heat transfer Efficiency, shortened life, increased energy consumption and increased costs. Solution: Prevent oxidation of heat transfer oil. Find the reason for the high temperature of the upper tank and remove the hidden danger. The hazards of excessively high oil temperature in the high tank. When using the fuel gas heat conduction oil furnace light oil burner, in addition to the furnace body itself, attention should also be paid to its connecting pipes and high temperature tanks, because of the influence of many factors Below, the pipeline and the upper tank may have the following failures, such as pipeline blockage, oil spill in the upper tank, etc. The connecting pipe of the fuel gas heat conduction oil burner and the light oil burner is generally made of steel. It will deform when the temperature changes greatly, which will cause the pipe to rupture. In this case, the heat stored inside cannot be dissipated in time, which may cause serious consequences such as explosion. In order to avoid similar dangers, on the one hand, the temperature of the light oil burner of the fuel gas heat conduction oil furnace must be controlled, and it must not be too high or too low; on the other hand, the pipeline must be maintained to prevent excessive dust and dirt accumulation. Cause blockage of the pipeline. The oil spill in the high tank of the light oil burner of the fuel gas heat conduction oil burner, on the one hand, may be due to unexpected situations such as failure of the circulating pump, sudden power failure, system leakage, etc., forcing the circulation of the heating system of the oil furnace to be interrupted, and the furnace The high temperature cannot fall in a short time, so the oil temperature rises rapidly, and the high-boiling and low-boiling substances in the heat transfer oil directly rush to the high-level tank and cause oil spill. On the other hand, it may also be that the heating rate of the fuel gas heat conduction oil burner and the light oil burner is too fast during dehydration and exhaust, so that the moisture in the heat conduction oil will rapidly generate steam, and the low boiling point volatiles in the heat conduction oil will be mixed with it and hit the high level. The phenomenon of oil spill caused by the groove. In order to prevent this problem from occurring in the light oil burner of the fuel-gas heat-conducting oil furnace, first of all, it is necessary to quickly stop the combustion, blowing, and extinguish the residual fire in the furnace, the purpose is to isolate the fuel-gas heat-conducting oil furnace light oil burner from the heating system; At the same time, the cold oil in the upper tank should be immediately flowed into the lower tank through the furnace tube to cool the furnace tube. What are the reasons for the high oil temperature of the high tank? Heat transfer oil is also called heat transfer oil. The official name is heat transfer oil (GB/T4016-83), the English name is Heat transfer oil, also known as 'organic heat carrier', the official name proposed in the national standard (GB/23971-2009), commonly known as 'heat transfer oil', Kerosene etc. The traditional heat carrier is water and steam. However, if water is used as a heat carrier above its boiling point, equipment and systems are required to withstand pressure. In industrial production at 150 to 350 degrees Celsius, heat transfer oil is a substitute for water vapor due to its high boiling point, which can greatly reduce equipment investment. Reasons for the high oil temperature of the high-position tank of the heat-conducting oil boiler diesel combustion engine 1. First, check whether the forced exhaust pipe is fully closed, whether there is internal leakage, and whether it is heated by hand. 2. Whether the height of the high slot is enough, it is best to be 3~5 meters away from the highest point of the system (including equipment), and 1.5~2 GB is obviously not enough. The higher the better. 3. System piping design problem, main line design is too detailed. 4. Reducing the circulation rate will cause the heat transfer oil to stay in the boiler diesel burner for too long, which is easy to cause the thermal cracking and thermal oxidation of the oil! 5. Take an oil sample, check it, and see the situation! Heat transfer oil boiler diesel The solution to the high oil temperature of the burner's high tank is first to consider whether there is a problem with the oil circuit. Second, your circulating pump is also public, so it can’t work. 5 million kcal is normal but 3 million kcal is alone. Run and then use the 5 million kcal circulating pump heat transfer oil to dissipate heat. Of course, the temperature of the upper tank will continue to rise. If this is the case, give you a solution. Add a circulating pump suitable for 3 million kcal next to the 5 million kcal circulation pump, and run one of them separately and turn off the other. The high tank is used to circulate the oil in the entire oil circuit, and the low tank is used to replenish the oil in the entire oil circuit. The specific natural circulation of the oil circuit goes from high to the bottom, and the forced circulation goes from low to high. The high position is hot and the low position is cold. What are the characteristics of heat-conducting oil boiler diesel combustion engine oil cleaning agent? High-efficiency oil cleaning agent can be pided into ordinary oil cleaning agent, low-foaming oil cleaning agent and heavy oil cleaning agent. It is compounded by a variety of surfactants, penetrants and auxiliary agents, and has the functions of penetrating, emulsifying, dispersing and peeling. It is specially developed for the cleaning of the production process of metal parts during the machining process. It has an excellent cleaning effect on grease, oil and mixed dirt.

Applicability: Low foaming is particularly suitable for spray cleaning machines, but also for ultrasonic cleaning machines. 5. Environmental protection: It does not contain phosphate, and the selected surfactant can be biochemically degraded and is safe for the environment. Introduction to the cleaning of heat-conducting oil boilers and diesel burners. Everyone knows that the attention function of cleaning agents is cleaning. Of course, different cleaning agents have different cleaning methods. Do you know how to clean the heat-conducting oil boiler light oil burner cleaning agent? Maybe a lot of people know a little bit, maybe a lot of people don’t know, it’s okay, in order to help consumers who don’t know to solve these questions, the following section will give you a detailed introduction to the use of the heat conduction oil furnace light oil burner cleaning agent :1. Drain the old oil: Use the heating system to heat the heat transfer oil to 70-80℃, and discharge all the heat transfer oil in the system while it is hot. According to the premise, the residual oil in the system can be released as much as possible. Participate in a small number of detergents through the soaking, peeling, dissolving effect to make the oil thinner, and then drain out of the system. 2. Pre-washing: The cleaning agent is added to the system at 2% of the total volume of the cycle. The solid is dissolved in hot water and the liquid is added together. At any part of the heating system (usually through the oil pump through the high oil tank, and the oil The method is the same) Put the system into the system, fill the system with clean water, open the cycle oil pump to cycle, use the heating furnace to raise the water temperature to 80℃±5℃, switch the relevant valve of each reactor in the system to make all parts of the system Parting gets reincarnation. After 6 to 8 hours (if there are more reaction kettles, you need to add a pre-wash time, make each kettle cycle independently for half an hour), turn on all the low-position drain valves of the system, and drain the water in the system. Then write water rinse from the beginning, heating (80℃±5℃) while rinsing has the best effect, until the water becomes clear, maybe slightly yellow PH value is the same as that of water. 3. Cleaning: Put the cleaning agent on the cycle total Participate in the system with 6-8% of the amount. After the solids are dissolved in hot water, the liquids will participate together. Same as (2) Put the system into the system and fill the system with clean water, open the cycle pump to cycle, use a heating furnace to heat the cleaning agent to 90 ℃±5℃. Switch the system valves so that all parts in the system can be cleaned. The valve switching should be done every hour. All cleaning time is no less than 24 hours (if there are many reactors and piping systems, cleaning time needs to be added). Turn over the cleaning arbitrary parts of the cycle pipeline to check the cleaning status. If there is still grease, add cleaning time until all the parts are stripped and cleaned and enter the next step. 4. Water washing: Fill the system with clean water, open the cycle pump to cycle, use a heating furnace to raise the water temperature to 90℃±5℃, switch the relevant valves in the system, and make all parts of the system reincarnate. Rinse the system. After three hours, turn on all low-position drain valves of the system to drain the water in the system. 5. Water washing: Fill the system with clean water again, turn on the cycle pump to cycle, use the heating furnace to raise the water temperature to 90℃±5℃, switch the relevant valves in the system, and make all parts of the system get cycle. . Rinse the system. After three hours, turn on all low-position drain valves of the system to drain the water in the system. 6. Water washing: Fill the system with clean water, open the cycle pump to cycle, use a heating furnace to raise the water temperature to 90℃±5℃, rinse the system, and after three hours, turn on all low-level drain valves of the system , Drain the water in the system. According to the cleaning status, it can be combined. During the flushing process of the high-efficiency oil cleaner, check the flushing status at any time until the flushing water is clear or slightly yellow. If there is still a clean place during the washing process, participate in a few medicine cycles for 1-2 hours, and the temperature should be 90℃±5. All the processes are carried out in hot water, and the oil pump is always homework. After the discharge is completed, according to the premise, the residual water in the system can be purged with compressed air until the discharge stops. 7. Add new oil: write new heat transfer oil into the system. 8. Dehydration: The dehydration method is equal to the dehydration standard before the new system is applied. Several tips for selecting metal high-efficiency oil stain cleaning agents. High-efficiency oil stain cleaning agents are mainly used for cleaning, oil removal, rust removal, scale removal, and rust prevention when the equipment of various enterprises and institutions has been used for a period of time. , Cleaning and maintenance, etc. The types of these equipment are complicated: such as mechanical equipment, electrical equipment, fine electronic equipment, water system equipment, various machines, special equipment, etc., the questions presented are also different. It is difficult to have one or two cleaning agents to deal with these equipment. Doubt, this requires professional manufacturers of industrial cleaning agents to develop a variety of products to reach the needs of the market. When choosing products, you can prescribe the right medicine, and choosing the right products is the key to handling questions. Because of the huge differences in production processes. Cleaning needs, begging and cleaning goals are also different, so there is a lot to do in the selection of suitable products. Under normal circumstances, when choosing high-efficiency oil cleaner products, it is necessary to think about the following factors: 1. Water should be used Basic cleaner or solvent cleaner: If the cleaning target needs to evaporate quickly and has a need for rust prevention, you can think about choosing a solvent cleaner. If the cleaning cost is low, there is no need for cleaning evaporation, and If rust prevention is not quick, you can choose water-based cleaners. 2. Whether to use an ultrasonic cleaner or a spray cleaning: This is also elegant when choosing a high-efficiency oil cleaner. If a water-based cleaner is used for cleaning in an ultrasonic cleaner, the need for foam is not very agile, and spray For washing, there is a demand for foam. The demand is a low-foaming degreasing and degreasing cleaner. This is a low-foaming degreasing and degreasing product type. It is suitable for spray cleaning (the spray cleaning varies with the pressure of the spray. The foam demand is also different. The higher the spray pressure, the more low foam is required. The spray pressure of the spray cleaner currently used by the company is usually around 3-20KG). But there is also an opposition. Most low-foaming detergents cannot be used because many excellent surfactants cannot be used. Therefore, its degreasing and degreasing ability is relatively weak, and its cleaning effect is difficult to achieve the effect of high-foaming detergents. This must be summed up when choosing a cleaning agent, everything has advantages and disadvantages. 3. After cleaning, rust prevention is required or not. This is another question: the cleaning agent used for cleaning of the production process is usually water-based cleaners, because the cost of water-based products is low and economical If the water-based cleaner does not have the function of rust prevention, it will accelerate the rust of metal materials. The reason is that removing the protective layer on the surface after cleaning will speed up embroidery. The selection should be based on the company's detailed situation. Similarly, everything has advantages and disadvantages. If water-based products add some anti-rust ingredients, these ingredients may reduce the cleaning performance of water-based cleaners, and their cleaning power may be reduced. !
