Description

Technical Field

[0001] The utility model belongs to the technical field of crude benzene processing equipment, and specifically relates to a high-efficiency cooling device for crude benzene production. Background Art

[0002] Crude benzene is one of the products of crude coal gas generated by coal pyrolysis. It is a benzene compound recovered from coke oven gas after deammoniation, with benzene content being the main component, and is called crude benzene. Crude benzene is a light yellow transparent liquid, lighter than water and insoluble in water. During storage, unsaturated compounds are oxidized and polymerized to form resinous substances that dissolve in crude benzene, and the color becomes darker. Crude benzene is an intermediate product, and its own use is extremely limited. It is only used as a solvent. Crude benzene is mainly used for deep processing to produce benzene, toluene, xylene and other products. Benzene, toluene and xylene are all valuable basic organic chemical raw materials.

[0003] In the crude benzene production process, since crude benzene is highly volatile and is a flammable and explosive Class A combustible liquid, the crude benzene storage tanks used for temporary storage and transportation of crude benzene must be equipped with effective insulation and cooling facilities. When the crude benzene storage tanks are exposed to a high temperature due to the influence of the external environment, it is easy to cause safety hazards and endanger the personal safety of the staff.

[0007] It is further defined that sealed bearings are connected between the transmission pipeline and the outer protective chassis, and between the feed pipe and the discharge pipe and the crude benzene storage box and the junction tube. Such a structural design can strengthen the sealing of the connection between the transmission pipeline and the outer protective chassis, and between the feed pipe and the discharge pipe and the crude benzene storage box and the junction tube to prevent penetration.

[0008] It is further defined that the side wall of the collector tube is provided with a circular concave. Such a structural design can increase the heat exchange area and accelerate the heat dissipation speed of the crude benzene storage tank.
