Waste gas filtering treatment device for environmental protection engineering

Abstract

The invention relates to a waste gas filtering treatment device for environmental protection engineering, which comprises a gas inlet pipe, a first filtering box is arranged at one end of the gas inlet pipe, and a first filtering mechanism is arranged in the first filtering box; the first filtering mechanism comprises an air blocking box, an ash discharging pipeline, an ash hopper, a first filtering plate, a filtering bag, a compressed air releasing rod, an electromagnetic pulse valve, a ventilating pipeline, an air blower and a second filtering plate, the air blocking box is arranged on the lower side in the first filtering box, the ash discharging pipeline is arranged at the lower end of the first filtering box, and the ash hopper is arranged at the lower end of the ash discharging pipeline. The device is simple in structure, stable in operation, low in initial investment, convenient to maintain and free of water, so that the problem of sewage treatment or mud treatment is solved, collected dust is easy to recycle, and the device is unique in material, safe, reliable, energy-saving, labor-saving, free of secondary pollution and capable of better meeting use requirements.

Description

technical field [0001] The invention relates to the technical field of waste gas filtering and processing devices, in particular to a waste gas filtering and processing device for environmental protection engineering. Background technique [0002] At present, industrial production and daily life will produce a large amount of harmful waste gas, and the waste gas needs to be treated before it can be discharged into the atmosphere, otherwise it will cause harm to the atmospheric environment. The general waste gas filtration treatment device includes water liquid supply device, ash pool, circulating pool, dedusting tower, grille filter. However, these waste gas filtration treatment devices generally have the disadvantages of high engineering cost, large equipment operation resistance, easy to produce secondary pollution such as sewage, low waste gas treatment rate, inconvenient maintenance, and failure to achieve environmental protection. problem solution.
