Embodiment Construction
[0022] The present invention mainly uses the clean blast furnace gas after dust removal by the blast furnace bag filter to replace the nitrogen to carry out back blowing and soot cleaning on the cloth bag. gas requirements. In order to further set forth the technical means and effects taken for the content of the present invention and reach the intended purpose of the invention, the detailed description is as follows in conjunction with the accompanying drawings:
[0023] refer to figure 1 As shown, the equipment involved in this process mainly includes: gas filter 1, cooler 2, gas compressor 3, buffer tank 4, gas dehydrator 5 and pressure regulating valve group 6. The clean blast furnace gas sent by the bag dust collector is further deashed through the filter, and after cooling, pressurization, dehydration and pressure regulation, it is used as a gas source to blow back the blast furnace bag filter.
[0024] The above steps specifically include:
