Embodiment Construction

[0029] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details.

[0030] In view of the problems of high energy consumption, easy blockage, and incomplete dust removal in the traditional dust removal device proposed above, the friction electrostatic dust removal device and dust removal method provided by the present invention are based on two types of dust removal devices with significant differences in work functions (significant differences in the ability to bind electrons). Materials rubbing against each other is easy to generate static charges. A friction electrostatic dust removal device is provided. Materials with high work function are used to rub against the air to make the air positively charged and guide the negative charges on the materials to the plate to...

Abstract

The invention provides a frictional electrostatic dust removal device and method. The frictional electrostatic dust removal device comprises a fan disc, a top cover, a water container, a turntable, a rotary shaft connected with the turntable and pole plates fixed to the turntable. Multiple fans are distributed on the fan disc, an electric brush is fixed to the fan disc, and an electric brush is fixed to the top end of the water container. The front end of the top cover is fixed to the fan disc, the rear end of the top cover is fixed to the water container, and the turntable is fixedly connected with the water container. Conductive pieces extending out of fan blades of the fans are in contact with the electric brush on the fan disc in a sliding mode. The conductive pieces extending out of electrode slices inside the pole plates are in contact with the electric brush fixed to the top end of the water container in a sliding mode. The electric brush fixed to the fan disc is connected with the electric brush fixed to the water container. The problems of high energy consumption, easy blockage and incomplete dust removal of a traditional dust removal device can be solved by means of the frictional electrostatic dust removal device and the method.

Description

technical field [0001] The present invention relates to the technical field of air purification, and more specifically, relates to an air purification device and a dust removal method which utilize electrostatic charge caused by friction to absorb dust in the air and recover it efficiently. Background technique [0002] At present, the situation of air pollution control in our country is very severe. Smog weather is common in large and medium-sized cities across the country, which has a serious impact on people's life, production and health. Coal combustion, vehicle exhaust, industrial waste gas, construction site dust, etc. are all factors that produce haze. The core substance of haze is dust particles suspended in the air. [0003] The current dust collection devices are mainly divided into filter type, wet type and electrostatic type. The filter type dust collection device is mainly composed of a suction pipe, a filter, and a vacuum pump, which has high energy consumption...
