Problems solved by technology

[0002] Benzene storage tank is a commonly used storage equipment in the coking process system. Because benzene contains a small amount of water, benzene and water will separate after benzene storage, and the density of water is greater than that of benzene. After a period of storage, it will usually appear at the bottom of the benzene storage tank. The water layer will seriously affect the quality and stability of benzene products, and the impurities in the water will also cause corrosion of the benzene storage tank

Abstract

The invention relates to a drainage device for a benzene storage tank. The drainage device comprises a benzene-water separation tank, a communication pipeline and an ultrasonic sensor, the benzene-water separation tank consists of a tank body, and a coalescer and a benzene full-flow cutting-out unit which are arranged in the tank body, a water inlet of the tank body is connected with a water outlet of the benzene storage tank through a communication pipeline, and a manual valve, an ultrasonic sensor and an electric valve are arranged on the communication pipeline; an upper baffle, a partition plate I, a coalescer, a lower baffle, a benzene full-flow cutting-out unit and a partition plate II are sequentially arranged in the tank body between the water inlet and the water outlet, and a benzene outlet is formed in the tank body corresponding to one side of the benzene full-flow cutting-out unit. Whether water exists in the communicating pipe or not is judged through the ultrasonic sensor, the benzene storage tank is automatically drained through the electric valve, drained water enters the benzene-water separation tank, benzene in the drained water is further separated out through standing and the coalescer, and finally separation of benzene and water is achieved.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a drainage device for a benzene storage tank. Background technique [0002] Benzene storage tank is a commonly used storage equipment in the coking process system. Since benzene contains a small amount of water, benzene and water will separate after storage, and the density of water is greater than that of benzene. After a period of storage, it will usually appear at the bottom of the benzene storage tank. The water layer will seriously affect the quality and stability of benzene products, and the impurities in the water will also cause corrosion of the benzene storage tank. Contents of the invention [0003] The invention provides a benzene storage tank drainage device, which judges whether there is water in the connecting pipe through an ultrasonic sensor, and automatically drains the benzene storage tank through an electric valve, and the drainage enters the benzene-water sep...
