Description

Technical Field

[0001] The utility model relates to the technical field of crude benzene production and processing, in particular to a temperature reduction device for crude benzene production and processing. Background Technique

[0002] Crude benzene is one of the products in the crude gas generated by the thermal decomposition of coal. Crude benzene is extremely volatile and is a Class A flammable liquid that is flammable and explosive. The tank area of the benzene hydrogenation system is a major hazard source. According to the requirements of the national standard GB17914-2013, the storage temperature of medium and high flash point flammable liquids is ≤37°C. In the hot summer season, the external temperature is relatively high, the tank body is directly irradiated by the sun, the temperature inside the tank rises, and more benzene substances volatilize, resulting in a large loss of benzene substances. At the same time, there are certain safety hazards. The volatilized benzene vapor accumulates on the top of the tank. If it encounters a spark or static electricity, it is extremely easy to cause a fire and explosion accident.

[0003] Therefore, in order to ensure that the temperature inside the tank is within a reasonable range and reduce the volatilization of benzene substances, it is necessary to set up a tank body spray. However, direct spraying will cause the cooling water to be unable to be recycled, wasting a large amount of water resources. The spray water enters the wastewater system, greatly increasing the difficulty and cost of wastewater treatment. At the same time, the spray water accumulates on the ground, resulting in a slippery ground, which is extremely easy to cause operators to slip and get injured. Therefore, it is very necessary to design a temperature reduction device for crude benzene production and processing with strong practicability and recyclable water. Content of the Utility Model
