The waste gas serious environment pollution that Industrial Boiler produces influence people's health, destruction ecological environment.So each state all gives the attention of height to treatment of waste gas.At present, to the dedusting of flue gas with remove the main method of sulphuring treatment and have: the combination of water law, cyclonic separation method, filtration method and chemical liquid ablution or these methods.Like " CN01127388.8-desulfation dust-extraction device ", adopt smoke filtration, hydrojet sulphur removal.And for example, " the multistage liquid film of CN1419953A-spray spray washing formula flue gas desulfurizing device " is provided with multistage desulfurizing tower in a cylindrical shell, and flue gas is from the air inlet of cylindrical shell bottom, the reverse mode that sulphur removal liquid sprays from top to bottom.There are following shortcoming in these dedustings and desulfurizing device: 1, complex structure; 2, the limited and time weak point of gas-liquid contact area, effect is bad; 3, anti-corrosion of metal poor performance, the life-span is short; 4, maintenance is difficult; 5 costs are high.
Summary of the invention
The closed dedusting and the desulfurizing device of a kind of boiler smoke that the utility model proposes, one of purpose be, it is simple that structure is wanted, and cost is low; Two of purpose is that the material antiseptic performance is good, long service life; Three of purpose is, gas-liquid contact time is long, and dedusting and sulfur limitation effect are good; Four of purpose is that maintaining is simple, easy.
A kind of closed dedusting and desulfurizing device of boiler smoke comprise storage cistern, it is characterized in that having multistage closed storage cistern and the blast pipe that communicates; Closed storage cistern contain water also leaves the locus above it; Boiler smoke gets into the locus of the closed storage cistern of the first order; The closed storage cistern of first order locus is communicated with the locus of the closed storage cistern in the second level; Closed storage cistern mode according to this is communicated with, and the locus of the closed storage cistern of final stage communicates with blast pipe, and boiler smoke is discharged from the blast pipe top.Closed storage cistern can reach and strengthen the area and the time of staying that contacts with water.
The closed dedusting and the desulfurizing device of above-mentioned a kind of boiler smoke is characterized in that spray equipment spray liquid is equipped with in the outlet top of the locus of the closed storage cistern of described final stage, and spray equipment communicates with blast pipe.
The closed dedusting and the desulfurizing device of described a kind of boiler smoke is characterized in that the closed storage cistern that has the 1-4 level to communicate.
The closed dedusting and the desulfurizing device of above-mentioned a kind of boiler smoke; It is characterized in that described closed storage cistern locus is divided into a high position and the low level two parts space that communicates: flue gas gets into closed storage cistern from the low bit space inlet of closed storage cistern locus, enters the low bit space inlet of the closed storage cistern of next stage locus then from the high bit space outlet of closed storage cistern.Purpose is after making flue gas be full of high low level two parts space, and flue gas just has enough pressure to get into the closed storage cistern of next stage, like this, has increased the time of contact of flue gas and water, dedusting better, and the hydroxyl OH in the water
-Absorb sulphur and oxide thereof in the flue gas, reduced the sulphur of flue gas and the content of sulfide thereof.
The closed dedusting and the desulfurizing device of above-mentioned a kind of boiler smoke is characterized in that described high low level two parts space is communicating near closed storage cistern liquid level place.This purpose is high low level two parts space that flue gas is full of closed storage cistern, and the flue gas pressure in closed storage cistern space is increased, and it need not increased under the condition of power, makes flue gas get into the closed storage cistern of next stage.
The closed dedusting and the desulfurizing device of above-mentioned a kind of boiler smoke is characterized in that described liquid is water or akaline liquid.Sulphur and sulfide in the flue gas further are removed.
The closed dedusting and the desulfurizing device of above-described a kind of boiler smoke is characterized in that described closed storage cistern has dust discharge slag charge mouth, so that discharge the precipitum in the closed storage cistern.
The closed dedusting and the desulfurizing device of above-mentioned a kind of boiler smoke is characterized in that the flue gas of the closed storage cistern of said entering first order locus is carried with air blast.
The closed dedusting and the desulfurizing device of above-mentioned a kind of boiler smoke is characterized in that described closed storage cistern makes with cement material.The cement material acid and alkali resistance, corrosion-resistant, raw material is cheap; Can easily safeguard closed storage cistern on the ground.
In a word, the utility model simple in structure, cost is low, and antiseptic property is good, processing ease, the working service cost is few.
