Coke oven gas water washing separator

Abstract

The invention discloses a coke oven gas water washing separator, comprising a tank, wherein a baffle is arranged on the inner wall of the tank for dividing the tank into an upper cavity and a lower cavity, the water washing cavity at the lower part communicates with the condensation separating cavity at the upper part by a through hole in the middle of the baffle, a sample gas introduction pipe is arranged on the top of the tank, one end of the sample gas introduction pipe serves as a mixed sample gas inlet while the other end stretches into the water washing cavity through the through hole in the middle of the baffle, a cold water inlet and a sewage drain hole are respectively arranged on the cavity wall of the water washing cavity, stainless steel fibers are filled in the condensation separating cavity, a sample gas outlet is also arranged on the cavity wall of the condensation separating cavity. The coke oven gas water washing separator has the advantages that cooling and scrubbing of the sample gas and separation of the condensate are effectively performed in the same device, the cooling and dedusting effects are significant, and meanwhile the problems that the pipe is easy to block, the maintenance workload is large and periodically coordinated operation cannot be obtained for a long time are solved.

Description

technical field [0001] The invention relates to the technical field of on-line gas analysis, in particular to a coke oven gas water washing separator. Background technique [0002] The sample gas scrubber is mainly used in the coke oven gas explosion-proof oxygen analysis system to ensure safe production. Coke oven gas contains heavy pollutants such as tar, naphthalene, and dust. The sample gas treatment of coke oven gas is one of the difficulties in the online analysis sample gas processing system technology. [0003] In modern industry, the coke oven gas sample gas treatment system mostly adopts technical schemes such as static water washing, kerosene washing, diesel washing, acyl oil washing, etc. These methods have no obvious effect on cooling and decontamination of the sample gas; The gas contains a large amount of water vapor, and in industry, a condensing device is usually installed after the cooling and dust removal system. In order to ensure the gas purification e...

Problems solved by technology

[0004] In order to solve the above problems, the present invention proposes a coke oven gas scrubber, which combines the water washing chamber and the condensation separation chamber, and the water washing chamber adopts the method of continuous cold water washing and filling stainless steel fibers in the condensation separation chamber to realize condensation and separation. The cooling of the sample gas, the decontamination and the separation of the condensate are carried out in the same device, and the cooling and dust removal effects are obvious. At the same time, it solves the problems of easy pipeline blockage, heavy maintenance workload, and long-term coordinated operation.
