Embodiment Construction

[0020] As shown in Figure 1-2, the wet desulfurization and dust removal device of this utility model is an integrated steel structure tower body, which is lined with glass fiber reinforced plastics and granite chips for anticorrosion and wear resistance. The special parts are made of 316L stainless steel. The furnace tail gas passages are connected, and the waste gas 1 is introduced into the pretreatment chamber 3 on one side of the tower body. The tower body also includes a discharge circulation system, which includes a circulating liquid 2 arranged at the base of the tower and a chimney 8 at the top of the tower; In the reverse direction of the tower body, there are also the following processing structural parts: self-excitation chamber 4, atomization spray chamber 5, gas-liquid separation chamber 6 and demist chamber 7; water pump 9 and water pipe 10 installed at the bottom of the tower body, shower and The treatment chambers are respectively connected, that is, the water pu...

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...
