Abstract

The invention discloses a condensate treatment subsystem of a coke oven gas purification system. The condensate treatment subsystem comprises a mechanical clarifying tank, a tar residue tank, a mixed liquid tank, a residual oil pump, a mixed liquid pump, an oil removal hydrocyclone, an in-water oil removal hydrocyclone, an ammonia water middle tank, an in-oil water removal hydrocyclone and a tar middle tank; residues, oil and water in condensate produced in the gas purification process are separated in the rotational flow centrifugal sedimentation principle, immediate treatment of the condensate is realized, the separation time is short, the separation effect is better, equipment is reduced, the investment is low, and small areas are occupied. The invention further provides the coke oven gas purification system containing the condensate treatment subsystem.

Description

Technical field [0001] The invention relates to the technical field of coking gas purification, in particular to a coke oven gas purification system and its condensate treatment subsystem. Background technique [0002] The raw gas produced in the coking process is sprayed with circulating ammonia water to cool down to 82~86℃ and then enters the gas-liquid separator. After gas-liquid separation, the gas enters the primary cooler and is cooled to around 22℃ with circulating water. The cooled gas After the tar mist is collected by electricity, it goes through the steps of blower, desulfurization, ammonium sulfate, final cooling, and benzene washing to obtain clean industrial gas. [0003] In the gas purification process, condensate is produced in the gas-liquid separator, primary cooler, electric tar trap and final cooler. At present, the condensate is generally separated by a mechanized clarification tank or a tar ammonia water separator to obtain tar residue, tar and ammonia water....
