Wet electrostatic precipitator, desulfurization system as well as desulfurization and dust removal process

Abstract

The invention discloses a wet electrostatic precipitator, a desulfurization system as well as a desulfurization and dust removal process. The desulfurization and dust removal process at least comprises the step of electrostatic precipitation in a transverse flow process of flue gas flow. The desulfurization system at least comprises one wet electrostatic precipitator. The wet electrostatic precipitator comprises a cylindrical dust removal box which is horizontally arranged and provided with an air inlet and an air outlet, air flow distribution plates are arranged in the dust removal box and close to the air inlet, a mist removal device is arranged in the dust removal box and close to the air outlet, and a dust removal device is arranged in the dust removal box and between the air flow distribution plates and the mist removal device. Electric conductors adopt tubular structures instead of the original sheet structures, the dust particle adsorbing areas of the electric conductors are increased in a use process, further, the intervals between rows of electric conduction tubes can distribute air flow very well, and air flow passes smoothly.

Description

technical field

[0001] The invention relates to a wet electric dust removal device, a desulfurization system and a desulfurization and dust removal process. Background technique

[0002] Most of the dust removal systems currently on the market are vertical dust removal devices installed in the desulfurization tower. This system has some defects during use:

[0003] (1) A large amount of flushing water and recovered slurry during the use of the existing dust collector will be damaged by the spray layer when it falls into the desulfurization tower, which will directly affect the desulfurization reaction in the desulfurization tower, resulting in insufficient reaction between flue gas and desulfurizer , at the same time, the flue gas will escape at the damaged place, resulting in a decrease in desulfurization efficiency;

[0004] (2) During the use of the dust collector in the tower, the falling slurry will affect the lower flushing system until the lower flushing system fails...

Examples

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] A desulfurization system used in the desulfurization industry described in the embodiment of the present invention is provided with a device for dedusting the exhausted waste gas in the system, and the device adopts a wet electrostatic precipitator. The use of the wet electrostatic precipitator is different from the traditional dust removal method. The wet electrostatic precipitator needs to be placed horizontally in the entire desulfurization system to replace the traditional vertical desulfurization tower design. like figure 1 and figure 2 As shown, the wet electrostatic precipitator includes a cylindrical dust removal box 1 placed horizontally and having an air inlet 2 and an air outlet 3. The air inlet of the dust removal box is connected to the exhaust gas discharge port in the desulfurization system. The air outlet of the box body is connected to the d...
