Wet desulfurization dust-removing device and processing method thereof

Abstract

The invention discloses a wet desulfurization and dedusting device. The device is connected with a boiler or an industrial kiln tail gas path by a blower fan, and a tower body is also connected with a circulating discharge system. The device is characterized by sequentially and mainly comprising the following treatment structure parts: a pretreatment chamber, a self-excitation chamber, an atomization spray chamber, a gas-liquid separation chamber and a demisting chamber; all the treatment chambers are respectively communicated with each other by water pumps, water pipes and a spray system arranged at the lower part of the tower body; and the treatment chambers are communicated with circulating liquor by the water pumps to form a circulation system. The treatment method comprises the following steps: firstly, the tail gas is blown into the pretreatment chamber of the device by the blower fan, and primarily contacts with the liquid in the pretreatment chamber, and initial soakage reaction is carried out on the tail gas and the liquid; then the tail gas enters the self-excitation chamber and the atomization spray chamber, and the gas is completely purified by a series of complex reactions such as gas-liquid mass transfer, acid-base neutralization, flocculation, and the like; finally, the gas enters the gas-liquid separation chamber and the demisting chamber for liquid-gas separation and demisting; the purified gas is discharged by a chimney and the liquid enters the circulation system for recycling. The wet desulfurization and dedusting device has the advantages of simple structure, good treatment effect, etc.

Description

technical field [0001] The invention relates to a boiler and industrial kiln tail gas desulfurization and dust removal device, in particular to a wet desulfurization and dust removal device with good purification treatment effect and a treatment method thereof. Background technique [0002] At present, the desulfurization and dust removal devices used in industrial exhaust gas generally adopt the stone tower structure, which has a large area, heavy weight, high foundation requirements, large system resistance, and high energy consumption. , It is easy to cause corrosion of the fan. For example, the application number is 03242811.1, the application date is March 31, 2003, and the invention name is a patent application for a stone water film swirling desulfurization and dust removal device, which includes the main tower and auxiliary tower of the stone water film dust collector. The external dehydrator and flue gas heater are connected in series at the lower part of the auxil...
