Multi-pole distribution combination type current inversion efficient electric precipitator

Abstract

The invention discloses a multi-pole distribution combination type current inversion efficient electric precipitator which comprises a shell, common electric field positive plates, common electric field negative poles, grating and blind positive plates, end electric field negative poles, front deflection baffles and rear deflection baffles. A smoke inlet is formed in the front end of the shell. A smoke outlet is formed in the rear end of the shell. The front deflection baffles are mounted at the front ends of the corresponding grating and blind positive plates. A first channel is formed behind each front deflection baffle. The front end of each first channel is sealed. The rear end of each first channel communicates with the smoke outlet. The rear deflection baffles are mounted at the rear ends of the grating and blind positive plates. A second channel is formed in front of each rear deflection baffle. The front ends of the second channels communicate with a front containing cavity. The rear ends of the second channels are sealed. According to the multi-pole distribution combination type current inversion efficient electric precipitator, by changing the air flow flowing direction and the flowing speed for multiple times, increasing the dust impact frequency and the like, the problems of back corona and reentrainment of dust are prevented effectively, superfine dust is collected more efficiently, and the dust collection efficiency is improved.

Description

technical field [0001] The invention discloses an electric precipitator, in particular to a high-efficiency electric precipitator which is impacted by final electric field airflow, changes direction multiple times, secondary distribution of airflow, and realizes final electric field check. Background technique [0002] A variable flow field high-efficiency electrostatic precipitator and Kulunger grid plate currently disclosed in the market have a structural feature that a front anode and a front cathode parallel to the gas flow direction are provided in the housing near the gas inlet. For the front electric field, a rear electric field that can change the path of the airflow is set in the shell close to the flue gas outlet, which provides a solution for the existing electrostatic precipitators that are prone to back corona phenomenon and large secondary dust. A certain solution has been proposed, but this rear electric field adopts a downstream flow conversion form with an a...

Problems solved by technology

[0003] In view of this, the present invention aims at the deficiencies of the existing technology, and its main purpose is to provide a multi-pole combined inverter current high-efficiency electrostatic precipitator, which can increase the frequency of dust impact and prolong the residence time by changing the air flow direction and flow velocity multiple times. The time and setting the gap between the blades effectively solve the problem that the high resistance particles cannot be absorbed and the secondary dust is raised
