Low-low-temperature electric dust remover

Abstract

The invention discloses a low-low-temperature electric dust remover, and relates to the technical field of low-low-temperature electric dust removers. The dust remover comprises a machine body; an electric dust removal device which is mounted on the machine body and is used for carrying out electric dust removal on the flue gas conveyed into the machine body; a controller which is mounted at the top end of the machine body, wherein the controller is used for controlling the electric dust remover to work; a heat exchange device which is used for cooling the flue gas and comprises a heat exchange assembly, an air distribution mechanism, a box body and an inserting assembly for installing the heat exchange assembly and the box body. According to the invention, the air distribution mechanism is arranged, and the inclination angles of the five blade plates are adjusted, so that the flue gas can uniformly flow through the heat exchange assembly in the heat exchange device, the uniform distribution of the flue gas is realized, the uniform cooling of the flue gas is facilitated, and the dust removal effect of the flue gas is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of low and low temperature electric dust collectors, and in particular relates to a low and low temperature electric dust collector. Background technique [0002] The low-low temperature electrostatic precipitator is to reduce the temperature of the flue gas to below the acid dew point through the flue gas cooler, about 90°C. It overcomes the bottlenecks of conventional electrostatic precipitator technology such as back corona caused by high specific resistance and difficult charging of fine dust. It is the main supporting technology for the "ultra-low emission" transformation of coal-fired power plants in recent years and has become the mainstream technology for dust control. [0003] However, the low and low temperature electrostatic precipitators currently on the market have certain defects during use. For example, there is no air distribution device inside the heat exchange device, which cannot achieve u...

Problems solved by technology

[0004] The purpose of the present invention is to provide a low and low temperature electrostatic precipitator to solve the problem that the uniform distribution of the flue gas cannot be realized in the above-mentioned background technology, resulting in uneven cooling of the flue gas, and it is not convenient for rapid replacement of heat exchange components, resulting in flue gas The heat exchange effect is poor, and the long-term use of the dust hopper will easily lead to the accumulation of dust on the inner wall, resulting in the problem of the dust hopper being blocked
