Description

Technical Field

[0002] In order to stabilize the pressure of mixed gas users, the existing plate mixed gas pressure station (separate pressure and separate mixing process) adds a large reflux pipe to the high-coke mixed gas to improve the mixing stability of the mixing station. The mixed gas reduced by users after the reduction is merged into the blast furnace gas network through the large reflux pipe. The reflux of unstable high-coke mixed gas (containing sulfur) mixed into the blast furnace gas network will cause the calorific value of the blast furnace gas system to fluctuate, affecting the calorific value of users, the stability of flue gas detection indicators and user safety. In order to optimize the use of gas, it is necessary to make rational use of the reflux circulating gas.

[0003] The existing exhaust gas circulation pipe is usually attached with smoke particles, has poor filtering effect, is inconvenient to disassemble and clean, occupies a large space, and has a relatively single function. Utility Model Content
