Novel wet-type electric dust removal device

Abstract

The invention relates to the field of dust removers, and provides a novel wet-type electric dust removal device. The electric dust removal device comprises a dust removal chamber and a sewage discharging chamber which are arranged up and down and communicate with each other, wherein the dust removal chamber is provided with two opposite side walls, an air inlet is formed in one side wall of the dust removal chamber, and the other side wall of the dust removal chamber is provided with a defogging area and an air outlet; a plurality of rows of dust collecting polar plates are arranged in the dust removal chamber and in the direction of from the air inlet to the air outlet, wherein a corona wire is arranged between every two adjacent dust collecting polar plates in each row of dust collectingpolar plates, and the coronas are electrically connected with a high-voltage power supply; two spraying pipes are arranged in a V-shaped opening of each dust collecting polar plate; and air enters the dust removal chamber through the air inlet and then is discharged from the air outlet after passing through the defogging area. According to the novel wet-type electric dust removal device, wet typespraying and electrostatic dust removal are combined together, dust is wetted, and the potential safety hazard of a dry type electrostatic dust remover due to the problems of friction, static electricity and the like is effectively solved; and furthermore, spraying is carried out on the backs of the dust collecting polar plates so that a quite small amount of water can form uniform water mist, and therefore, the water spraying amount can be effectively reduced, and dust removal efficiency can be improved.

Description

Technical field [0001] The invention relates to the field of dust collectors, and specifically provides a wet electrostatic dust collector. Background technique [0002] In the context of the rapid increase in the emission of a series of air pollutants caused by the rapid economic development of our country, the continuous emergence of severe weather has affected our human health and the sustainable development of society. Electrostatic dust removal device is currently the most widely used dust removal and purification device in industry. Although it has high dust removal efficiency, low energy consumption, and large flue gas processing capacity, it still has problems such as complex equipment structure, large volume, and high cost. The dust treatment effect is insufficient; the traditional wet dust collector has a high collection efficiency for fine particles and acid aerosols, but there are also many shortcomings, such as the large difference in humidity between the upper and l...
