Abstract

The invention discloses a coke oven coal gas purification apparatus, and relates to a coal gas purification apparatus. In the prior art, during the steelmaking producing process, the combustion nozzle of the continuous casting blank cutter and the valve sheet of the continuous casting coal gas pressuring station compressor are generally blocked due to tar and naphthalene carbon deposition, such that the frequencies of stop production and maintenance of the continuous casting coal gas pressuring station compressor and the continuous casting blank cutter are increased. According to the apparatus, a water bucket, a first-order dehydration and decoking assembly, a second-order decoking assembly and an upper cover sequentially form a sealed connection from the bottom to up. A lower end of the water bucket is provided with a water outlet. A side wall of the first-order dehydration and decoking assembly is sequentially provided with an unpurified coal gas inlet and a first manhole from the bottom to up. A side wall of the second-order decoking assembly is provided with a second manhole. The top end of the upper cover is provided with a purified coal gas outlet. The apparatus provided by the present invention is applicable for the users using the refined coal gas and the steelmaking production using the refined coal gas.

Description

technical field [0001] The invention relates to a gas purification device, which belongs to the technical field of refined gas purification and steelmaking supporting equipment. Background technique [0002] In steelmaking production, the compressor of the continuous casting gas pressurization station and the continuous casting slab cutter use the refined gas that needs to be purified as the coke oven gas medium. However, the gas purification effect of many enterprises is not good. The burners of the continuous casting slab cutter and the compressor valves of the continuous casting gas pressurization station are often blocked due to tar and naphthalene carbon deposits. Continuous casting slab cutter shutdown frequency. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the continuous casting slab cutter burner and the continuous casting gas pressurization station compressor valve plate are often blocked due to tar and naph...
