Description

Technical Field

[0001] The utility model relates to the field of environmental protection, in particular to environmentally friendly dust removal and high-temperature flue gas purification equipment. Background Art

[0002] In the industrial production of steel and nonferrous metal smelting, a large amount of fuel is needed to heat the metal materials in the furnace. These fuels will produce a large amount of high-temperature furnace gas during the combustion process. Since the high-temperature furnace gas is not only high in temperature after being discharged from the heating furnace, but also contains a large amount of smoke and dust, if it is directly discharged, it will cause serious pollution to the environment. Therefore, when the high-temperature furnace gas is discharged, it needs to be cooled and dust-removed and purified to avoid damage to the ecological environment.

[0003] In the actual use process of traditional high-temperature furnace gas purification and emission devices, most of them discharge high-temperature furnace gas into a treatment box, and the nozzle in the treatment box cools down the high-temperature furnace gas, which can effectively cool down the high-temperature furnace gas and remove the smoke in the furnace gas. However, after the smoke contacts with water, a large amount of sludge will be generated. A filter plate is set in the treatment box to separate mud and water, but there is no cleaning structure for the filter plate. The sludge formed after the smoke contacts with water will gradually accumulate on the filter plate, causing the filter plate to be blocked. This not only reduces the filtration efficiency, but may also affect the normal operation of the entire purification and emission system.

[0004] Therefore, it is necessary to provide a new environmentally friendly dust removal high-temperature flue gas purification equipment to solve the above technical problems. Utility Model Content
