Heating system of tank semi trailer

In the process of oil transportation, there is often a problem that the oil cannot be successfully exported from the large tank semi-trailer because the temperature of the oil is too low. And large tank truck local rapid heater successfully solved this problem, can successfully help the tank car oil heating, so what is the characteristics of this heating, next, follow Xiaobian together to understand it.

Heating tank used to transport lubricating oil, heavy oil and other liquid tank cars, generally in the ordinary tank or insulation tank on the basis of the addition of heating system, constituting a heating tank car.

The heating system of tank car wave plate usually adopts exhaust gas heating, steam heating, electric heating and other heating methods.

1. Exhaust gas heating system

The characteristic of the exhaust gas heating system is that it can use the heat of the engine exhaust gas, and the heating is more uniform, but the tank structure is complex.

2. Steam heating system

A number of winding fin tube (or serpentine tube) heat exchangers are arranged in the tank body of the oil tanker, which are connected with the external steam source through special pipe joints, and heat the oil in the tank body by the steam heat incoming from the outside. The system is characterized by fast heating, uniform heating, relatively simple structure, light weight and wide application. Most oil tank cars are equipped with steam heating system to ensure normal operation in cold season. However, it must be used in conjunction with an air source that can provide steam.

3. Electric heating system

Electric heating The tank body of the oil tanker is equipped with a number of infrared heaters, which are energized to heat the oil in the tank body. The system is characterized by simple structure and high heating efficiency. However, because the heating surface is concentrated, it is easy to produce coking phenomenon around the heater. Therefore, the method of heating and stirring oil can be used to overcome this problem.
