Electrostatic composite metal-filler wet-type dust removing and filtering device and filtering method

Abstract

The invention relates to an electrostatic composite metal-filler wet-type dust removing and filtering device and a filtering method. A high-pressure metal nozzle group is embedded in the upper part of the dust removing and filtering device, a water inlet port of the high-pressure metal nozzle group is externally connected with a water pipe, and the water pipe is connected with a water storage tank through a water pump. A corrugated metal filler is arranged at the lower part of the high-pressure metal nozzle group, a water baffle board is installed in the air outlet position, and the bottom ofthe dust removing and filtering device is connected with a water storage pond. One end of the dust removing and filtering device is an air inlet pipe, and the corresponding end of the dust removing and filtering device is an air outlet pipe. A rectifier and booster transformer is arranged outside the dust removing and filtering device, and the rectifier and booster transformer is connected with each nozzle of the high-pressure metal nozzle group through conductors in parallel. Sprayed water drops form charged spray mist with small particle size, the mist drops are sprayed in the metal filler to form a charged water film, the charged water film produces an image force with tiny dust particles, and thus, the dust particles are humidified, condensed and weighted to be captured. The dust removing and filtering device has a simple structure, the dust particles and microorganisms can not retain in the metal filler, secondary pollution is avoided, and the dust removing and filtering device has higher filtering efficiency toward particles of more than 1 mums and aerosol particles of 0.5-1 mum.

Description

technical field [0001] The invention relates to an electrostatic composite metal filler wet dust removal filter device and a filter method, belonging to the technical field of air filter and purification equipment. Background technique [0002] At present, there are three major challenges in the air-conditioning industry: health, energy saving and environmental protection. In recent years, many studies have shown that the quality of atmospheric air is not optimistic, coupled with the physical and chemical pollution of some buildings, insufficient introduction of fresh air for air conditioning, and poor operation and management, leading to deterioration of indoor air quality. There are a large number of harmful substances such as aerosols, microorganisms and chemical gaseous pollutants in the air, which endanger human health and affect production. [0003] Current air-conditioning systems generally use primary and secondary filters to improve indoor air quality. However, th...
