Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to a gas drainage system. Background Art

[0002] In metallurgical enterprises, processes such as coke oven coking, blast furnace ironmaking, and converter steelmaking require the recovery and use of a large amount of gas, including coke oven gas, blast furnace gas, and converter gas. These gases contain a lot of water during the production process, including mechanical water and saturated water; in addition, the gas needs to be pressurized and transported over long distances when it is delivered to users, which will cause changes in temperature and pressure, resulting in a large amount of condensed water from the gas, which accumulates in pipelines and equipment. A large amount of condensed water will not only occupy the volume of pipelines and equipment, increase their load, and cause water hammer effect, but also cause corrosion of pipelines and equipment, which may cause gas leakage and safety accidents, which is not conducive to the subsequent treatment and use of gas. Therefore, the condensed water needs to be discharged in time. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a gas drainage system.

[0004] The utility model adopts the following technical solutions:

[0005] A gas drainage system comprises: a water-sealed gas drainer and a gas-liquid separator; the water-sealed gas drainer is arranged at a gas pipeline separated by a gas compressor and close to a gas transmission source, and the gas-liquid separator is arranged at the gas compressor or at a gas pipeline separated by a gas compressor and far from a gas transmission source.

[0006] Furthermore, the water-sealed gas drainer and the gas-liquid separator are both connected to the sewage tank through the drainage well.

[0007] Furthermore, the gas-liquid separator is a gas-liquid separation device with liquid level monitoring.

[0008] Furthermore, the locations where the water-sealed gas drainer is set are divided into two categories, one is the gas pipeline close to the gas transmission source, and the other is the gas pipeline close to the gas compressor.

[0009] Furthermore, the locations where the gas-liquid separator is set are divided into two categories, one is directly connected to the gas compressor, and the other is located on the gas pipeline close to the gas transmission outlet.
