Description

Technical Field

[0001] The utility model relates to the technical field of coal gas recovery, in particular to a steelmaking converter coal gas recovery and utilization device. Background Art

[0002] During converter steelmaking, a large amount of waste gas containing carbon monoxide and many impurities will be generated. Direct emission will cause waste of resources and environmental pollution. The purpose of protecting the environment can be achieved by filtering and absorbing the waste gas and recovering the usable gas resources in the waste gas.

[0003] After searching, a Chinese patent discloses a steelmaking converter gas recovery and utilization device, and its authorization announcement number is CN209010553U. The steelmaking converter gas recovery and utilization device can separate iron oxide dust particles and high-concentration carbon monoxide gas by setting a filter box and a heating box, using four filter layers, so that only high-concentration carbon monoxide gas is left in the residue, and the gas is passed into the storage chamber, and the high temperature of the gas is used to heat the water in the liquid storage chamber, so that the gas is recovered and utilized at the same time, thereby achieving the purpose of gas recovery and utilization, thereby avoiding the problem of direct discharge to the outside to pollute the environment;

[0004] However, this patent is not convenient for disassembling, cleaning or replacing the filter layer during use, and there are defects in its use.

If it is not cleaned, it is easy to affect subsequent filtration. Therefore, it needs to be improved. For this reason, we propose a steelmaking converter gas recovery and utilization device to solve the above problems. Utility Model Content
