Problems solved by technology
[0007] The technical problem to be solved by the present invention is that, in the prior art, the blowing method of dust removal blower or the addition of a dust collector or a dust cover is used to process the dust in the prior art, resulting in a large waste and poor effect; Most of the waste water produced in the smelting process has not been utilized by existing technologies, which not only pollutes the environment, occupies other storage resources, but also causes technical problems such as waste of production costs.

Embodiment Construction
[0018] In the steelworks in the prior art, how to reduce the production cost, how to improve resource utilization efficiency, energy recycling rate, sewage recycling rate, etc. starting from three aspects, how to effectively implement circular economy has always been a major problem in the production process problem. Under the unified deployment and arrangement of relevant departments, the sewage generated in the existing production process is used: steelmaking sludge, rotary hearth furnace sewage, and concentrated water from furnace A coal washing sewage are sprayed into the two machines through pipelines and pumps and returned to the two machines. Re-centering outside the seat furnace and replenishing water with calcium chloride can increase the original moisture of sintering raw materials, reduce water addition to the mixer, and at the same time play a role in dust suppression, effectively improving the environmental conditions of the production site. At the same time, from...

The invention discloses a dust suppression method and equipment applied in the smelting process. The equipment comprises sewage pools, slurry pumps, transmission pipelines and terminal water fillers, wherein one end of each of the slurry pumps is connected with the sewage pools and the other end of each of the slurry pumps is connected with the terminal water fillers via the transmission pipelines; and the terminal water fillers are open water tanks. The method and the equipment have the following beneficial effects that: by reasonably recycling the sewage generated in the production process, not only is the problem of sewage drainage solved, but also consumption of new water is reduced, at the same time, reentrainment on the field is obviously controlled, the operating environment on the production field is effectively improved and power consumption of the fabric-forming fans is reasonably controlled, thus greatly saving the sintering operating cost; and the method and the equipment have the following characteristics that: not only can environmental pollution be reduced, but also resource losses in the enterprises can be reduced and the slagging cost can be reduced.
Description
technical field [0001] The invention belongs to a process method and equipment in the smelting industry, in particular to a dust suppression method and equipment used in the smelting process. Background technique [0002] With the rapid development of the iron and steel industry in recent years, the country has higher and higher requirements for energy conservation and emission reduction in the iron and steel industry, requiring enterprises to treat or reduce emissions of waste gas, waste and dust generated in the steelmaking process. [0003] At present, most iron and steel enterprises do not have special integrated equipment or methods to solve the problems of wastewater, waste and dust generated in the above-mentioned production process. There are many technical problems in the existing treatment methods: [0004] 1. In the existing technology, dust removal fans are mostly used to deal with the dust generated in the smelting process. When working, multiple high-power fans...
