Abstract
The invention discloses an efficient desulfurization spraying tower. The efficient desulfurization spraying tower comprises a spraying tower, a spraying system and a slurry pond, wherein the spraying tower is provided with an air inlet and an air outlet; the spraying system is located in the spraying tower; the spraying system comprises a main water pipe, a first spraying pipe, a second spraying pipe and a third spraying pipe; the first spraying pipe, the second spraying pipe and the third spraying pipe are all connected with the main water pipe; a plurality of shower nozzles are mounted on the first spraying pipe, the second spraying pipe and the third spraying pipe; and the slurry pond is located below the spraying system. According to the efficient desulfurization spraying tower, the plurality of spraying pipes are mounted in the spraying tower and the spraying pipe at the center spirally ascends; meanwhile, the shower nozzles on the spraying pipes are air atomization nozzles so that slurry in the spraying system can come into sufficient contact with sulfur-containing smoke in the spraying tower and the desulfurization efficiency is improved; the slurry can be circulated by a water pump and the sulfur removing cost is reduced.
Description
[technical field]
The present invention relates to the technical field of the technical field of desulfurizer, particularly desulfuration spray tower.
[background technology]
Sulfur dioxide affects larger gaseous contaminant in atmosphere pollution, has high risks to human body, environment and the ecosystem.Along with the increasingly stringent of environmental requirement, the problem of S02 discharge more and more receives publicity.Sulfur dioxide mainly stems from the combustion process of the fossil fuel such as coal, oil, and the roasting of ore, the fume emission of smelting process.Wherein various burning boiler particularly power plant boiler smoke evacuation there is the features such as concentration is low, exhaust gas volumn is large, floating dust is many and be difficult to administer.Discharge sulfur dioxide in flue gas purification techniques normally carries out desulfurization by spray column, but the slurries in the spray system in traditional desulfuration spray tower can not contact with Gas phase Smoke fully, cause sulfur removal effectiveness lower.
[summary of the invention]
Object of the present invention solves the problems of the prior art exactly, proposes a kind of efficient desulfurization spray tower, and the slurries in spray system can be made fully to contact with the sulfur-containing smoke gas in spray column, improves desulfuration efficiency.
For achieving the above object, the present invention proposes a kind of efficient desulfurization spray tower, comprise spray column, spray system and slurry pool, described spray column is provided with air inlet and gas outlet, spray system is positioned at spray column, described spray system comprises water main, the first shower, the second shower and the 3rd shower, described first shower, the second shower are all connected with water main with the 3rd shower, first shower, the second shower and the 3rd shower are all provided with some shower nozzles, and described slurry pool is positioned at the below of spray system.
As preferably, described gas outlet is positioned at the upper end of spray column, and air inlet is positioned at the below of gas outlet.
As preferably, described second shower is between the first shower and the 3rd shower, and the second shower is in spiral shape is positioned at spray column, and the first shower and the 3rd shower are all vertically arranged in spray column, and described shower nozzle adopts air atomizing shower nozzle.
As preferably, the spray column that described slurry pool is positioned at below air inlet is inner, is provided with slurries oxidation unit in slurry pool, and slurry pool adopts water pump to be connected with water main, and the bottom of slurry pool is provided with gypsum excavationg pump.
Beneficial effect of the present invention: the present invention by installing some showers in spray column, be positioned at the shower rising in spiral shape at center, shower nozzle simultaneously on shower all adopts air atomizing shower nozzle, the slurries in spray system can be made fully to contact with the sulfur-containing smoke gas in spray column, improve desulfuration efficiency, water pump can recycle slurries, reduces sulphur removal cost.
Feature of the present invention and advantage will be described in detail by reference to the accompanying drawings by embodiment.
