Preparation method of efficient dedusting module

Abstract

The invention discloses a preparation method of an efficient dedusting module, and belongs to the technical fields of dedusting and environmental protection. The method comprises the steps that firstly, dust particles in airflow are charged with electricity through a pre-charger; airflow passes through cylindrical metal pore passages filled with twisted wire brushes; the wall surfaces of the pore passages and brush handles of the twisted wire brushes in the pore passages are loaded with voltage; and the dust particles entering the pore passages fly to the wall surfaces of the pore passages or the brush handles of the twisted wire brushes according to the principle that opposites attract, dust is captured, captured dust is not liable to escape under the action of brush bristles, and when the surfaces of the brush bristles of the twisted wire brushes are coated with a viscous insulating liquid, dust can be firmly adsorbed. The module is low in resistance, high in dedusting efficiency and relatively suitable for dedusting purification of indoor air.

Description

technical field [0001] The invention relates to a method for preparing a high-efficiency dust removal module, which belongs to the technical field of dust removal and environmental protection. Background technique [0002] With the rapid development of my country's economy, the haze air pollution in large and medium-sized cities, economically developed areas and areas with intensive basic industries in my country is becoming more and more serious. As my country's restrictions on SOx and NOx emissions become increasingly stringent, and related environmental protection technologies and devices continue to be put into use, the total emissions of SOx and NOx pollutants in my country's atmospheric environment have decreased year by year. However, from the current monitoring results, my country's Yangtze River Delta The haze pollution in the Pearl River Delta and Beijing-Tianjin-Hebei areas has not been significantly reduced, and has seriously threatened the health of the people an...

Problems solved by technology

[0004] The most mature indoor air particle removal technology is the use of HEPA filter elements, which is also the technical solution adopted by most air purifier manufacturers. However, HEPA has a large pressure drop, resulting in high noise and high energy consumption of power equipment. At the same time, HEPA cannot be cleaned and must be cleaned regularly. Replacement, so the cost of HEPA leads to high operating expenses for indoor air cleaners

The research team prepared a low air resistance gas particle purification module (ZL201210418554.4) by stuffing twisted wire brushes into the pores of porous media. Particle removal is poor

The technical solution of spray water washing is also used in some air purification devices, but the spray will cause excessive humidification of the indoor air, and its particle removal effect is not high. At the same time, because the spray water is often tap water, the salt caused by the hardness of the water makes the spray droplets After volatilization, it increases the number of particles in the indoor air

The research team also developed a semi-wet electrostatic dust removal (demisting) device (CN201510593461.9), which uses a circular plate partially submerged under the liquid surface as a dust collector, and the positive and negative charges are staggered. The device can efficiently remove the fine particles and avoid the secondary escape of dust in the common dry electrostatic precipitator process. However, the structure of the device is complicated, the processing is difficult, and it must be placed at a high level. Otherwise, electrical breakdown accidents between liquid tanks of different electrical properties will occur
