Heating technology of double-layer oil tank

With the continuous progress of people on the environment and resources, from the original single-layer oil tank to the current double-layer oil tank, due to the different storage methods before, it is easy to leak, causing great damage to resources Waste also has a certain impact. Heating the double-layer oil tank can extend the service life of the oil tank. The following will introduce several methods for heating the double-layer oil tank.
 
Heating technology:
1. Heating method of oil tank hot water cushion layer. It relies on the hot water cushion layer under the oil product to transfer heat to the oil product. Constantly replenish hot water and take away the cold water to maintain the temperature of the hot water cushion, you can use steam to supplement the heat. This method is used when there is a convenient source of hot water.

2. Pressure vessel steam or hot water indirect heating method is to pass steam or hot water into the tube heater in the oil tank or the heating jacket of the tank car to make it warm up and heat the oil. Steam or hot water do not directly contact oil products, and are widely used at present.

3. The hot oil circulation heating method of the double-layer oil tank is to continuously draw a part of the oil product from the oil storage pressure container, heat it, and then return to the container to mix with the cold oil. Accompanied by mechanical stirring. Heat transfer is faster. 4. The hot oil circulation heating method of the oil tank is to continuously draw a part of the oil product from the double-layer oil tank, after heating, then return to the pressure vessel and mix with the cold oil. Accompanied by mechanical stirring. Heat transfer is faster. Although it is necessary to add a circulation pump, a heat exchanger, etc., there is no need to install a heater in the oil tank. This method eliminates the heater leakage and affects the oil quality enough, and can also avoid heater corrosion and corresponding maintenance work.

5. The double-layer oil tank steam direct heating method is to directly pass saturated water vapor into the heated oil. This method is easy to operate and has high thermal efficiency, but condensed water will affect the quality of oil. It is only suitable for fuel oil, agricultural diesel oil and other oil products that do not require high water content.

6. Electric heating method of oil tank. There are three types of resistance heating, induction heating and infrared heating. The infrared heating method has simple equipment, high thermal efficiency and convenient use, and is suitable for heating pressure
vessels and tank trucks. There are also solar heating methods.
