Hydroelectricity dust catcher

Abstract

The invention discloses a hydroelectricity dust catcher. An electric field region is arranged in an upper part of a box body, the electric field comprises multiple pairs of positive electrode dust collection plates and negative electrode lines, the multiple pairs of the positive electrode dust collection plates are arranged at intervals and in parallel, the negative electrode lines are arranged between each pair of positive electrode dust collection plates, spraying devices are arranged above the electric field region and are used for spraying purified water to the positive electrode dust collection plates, an atomizing humidification layer is arranged below the electric field region, a turbulence region is arranged below the atomizing humidification layer, a smoke inlet is higher than a position of the turbulence region, the turbulence region comprises bending plates which are arranged in parallel, each bending plate comprises a plurality of repeated units, each repeated unit is formed by connecting a first vertical plate, a left inclination plate, a second vertical plate, a right inclination plate and a third vertical plate in an end-to-end way, the lengths of the first verticalplate, the left inclination plate, the second vertical plate, the right inclination plate and the third vertical plate are equal, and angles of bending positions of the bending plates are equal and are all 140-170 DEG C. The hydroelectricity dust catcher is high in dust removal efficiency.

Description

technical field [0001] The invention relates to the field of dust removal, and specifically provides a wet electrostatic precipitator. Background technique [0002] The wet electrostatic precipitator includes a box body and an anode dust-collecting plate arranged in the box. The anode dust-collecting plates are arranged in parallel, and several needle-punched wires are arranged between adjacent anode dust-collecting plates. Water pipe, the main nozzle is connected to the process water pipe; [0003] By applying a negative high voltage to the cathode of the electric field, the air in the electric field is ionized to generate charges. When the smoke passes through the electric field, it collides with the charges to achieve charging. The electrostatic field force between the anode and the cathode charges the smoke and dust to the anode plate and the cathode. A layer of water film is formed on the surface of the anode dust collecting plate by means of other methods, and the cle...

Problems solved by technology

[0003] By applying a negative high voltage to the cathode of the electric field, the air in the electric field is ionized to generate charges. When the smoke passes through the electric field, it collides with the charges to achieve charging. The electrostatic field force between the anode and the cathode charges the smoke and dust to the anode plate and the cathode. A layer of water film is formed on the surface of the anode dust collecting plate by means of other methods, and the cleaning water flows downward under the action of gravity, washes away the dust deposited on the plate, and falls into the ash hopper below the dust collector. Fine particles and acid aerosols have high capture efficiency, but the dust removal effect needs to be improved
