Flue gas conditioning device based on electric precipitator

Abstract

The invention discloses a flue gas conditioning device based on an electric precipitator, and belongs to the technical field of energy conservation and environmental protection, the flue gas conditioning device comprises a flue gas channel, the upper end part of the flue gas channel is communicated with an exhaust pipe, the left lower side of the flue gas channel is communicated with a gas inlet pipe, and the flue gas channel is internally provided with a flow guide piece, a humidity conditioning device, a distribution plate and a wet electric precipitator from bottom to top in sequence; the humidity conditioning device comprises an upper sealing plate and a lower sealing plate, the upper sealing plate and the lower sealing plate are connected through a plurality of cylinders, flue gas humidity adjusting strips are arranged in the cylinders and comprise a plurality of guide strips which are spirally distributed and alternately arranged, the cross sections of the guide strips are triangular, and first guide grooves are formed in the positions, connected with the upper sealing plate, of the cylinders. A second guide groove is formed in the position, connected with the lower sealing plate, of each cylinder, a bent pipe is arranged at the end, inserted into the inner side of the flue gas channel, of the gas inlet pipe, and a flow guide plate is arranged in the bent pipe. The dust removal effect of the electric precipitator is improved, the harm of flue gas to the environment is reduced, and the safety in flue gas dust removal is guaranteed.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to a flue gas conditioning device based on an electric dust collector. Background technique [0002] With people's requirements for environmental protection, the problem of boiler smoke and dust is becoming more and more prominent. In order to solve the above problems, people have developed many dust removal equipment. Wet electrostatic precipitator is one of them. The internal structure of the wet electrostatic precipitator generally has polar plates and polar lines. High voltage is loaded between the polar plates and the polar lines. The dust is charged, and the charged dust is attracted by the high-voltage electric field, and will travel towards the polar plate of the opposite electrode and be captured by the polar plate. In order to ensure good dust removal efficiency, it is generally required: first, the flue gas enters the electrostatic pre...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a flue gas conditioning device based on an electrostatic precipitator, which can effectively solve the problems of the existing flue gas conditioning device based on an electrostatic precipitator. If there are too many water droplets, the flue gas volume or speed is unstable, it cannot guarantee that the flue gas will achieve a good piston-like forward feature.

And for the flue gas, the treatment effect of water droplets is difficult to guarantee, resulting in the problem that the dust removal of the dust collector for the flue gas is not thorough enough, which has a great impact on the surrounding environment
