Embodiment Construction

[0014] The present invention will be further described below in conjunction with embodiment:

[0015] A desulfurization and dust removal process with remarkable effect, the specific steps are as follows:

[0016] (1) The induced draft fan introduces the flue gas from the boiler into the electrostatic precipitator. Under the action of the high-voltage electric field, some dust particles in the flue gas are adsorbed to the positive pole of the electric field along with the electrons, so that the flue gas can be preliminarily dedusted;

[0017] (2) The flue gas after preliminary dedusting is introduced into the desulfurization tower, and the blower makes the flue gas form an upward moving swirl in the desulfurization tower;

[0018] (3) The spraying device in the middle of the desulfurization tower sprays the desulfurizer solution into the flue gas, desulfurizes the flue gas, and removes sulfur and its compounds in the flue gas;

[0019] (4) The dehumidification device at the to...

Abstract

The invention provides a desulfurizing and dedusting process with remarkable effects. The process comprises the following specific steps: flue gas is introduced into an electrostatic precipitator froma boiler by an induced draft fan, part of dust particles in the flue gas are adsorbed to an anode of an electric field along with electrons under the action of the high-voltage electric field, and primary dedusting of the flue gas is realized; the flue gas after primary dedusting is introduced into a desulfurizing tower, and upwards moving cyclone is formed by the flue gas in the desulfurizing tower under driving of a blower; a desulfurizing agent solution is sprayed to the flue gas by a spray device in the middle of the desulfurizing tower to desulfurize the flue gas; a dehumidifying deviceat the top of the desulfurizing tower dehumidifies the desulfurized flue gas, and excessive moisture in the flue gas is removed; dehumidified flue gas enters a bag-type dust collector for further dedusting, and after dedusting, the desulfurized and dedusted flue gas is discharged into the air through a chimney. Single equipment is low in load, maintenance frequency is reduced, maintenance cost isreduced, equipment corrosion and secondary pollution caused by the flue gas are avoided, the service life of the equipment is prolonged, and the flue gas can meet the discharge standard.

Description

technical field [0001] The invention relates to the field of environmental protection technology, in particular to a desulfurization and dust removal technology with remarkable effect. Background technique [0002] At present, my country's power generation industry and iron and steel industry are still using coal for production. The smoke and dust generated after coal combustion contains a lot of harmful substances. The current emission standards require desulfurization and dust removal before exhausting the smoke. The existing desulfurization and dust removal methods are too simple and the equipment load is too heavy, resulting in frequent maintenance, and the simple superposition of desulfurization and dust removal links is likely to cause corrosion of equipment and secondary pollution of flue gas, shorten the service life of equipment, and make the gas reach less than emission standards. Contents of the invention [0003] The invention aims to solve the deficiencies of...
