The boiler tail gas treatment device disclosed by the utility model has the beneficial effects that smoke gas is in collision contact with alkali liquor many times and penetrates through multiple layers of micro water curtains in the filter column, so that the smoke gas sufficiently contacts the alkali liquor; the device has two functions of desulfurization and dust removal by collision, and water bath desulfurization and dust removal by water curtains.

Description

A kind of boiler exhaust gas treating apparatus with smoke filtration post
Technical field
The utility model belongs to vent gas treatment technical field, is specifically related to a kind of boiler exhaust gas treating apparatus with smoke filtration post.
Background technology
Existing boiler is fuel mainly with living beings such as coal or rice husk, stalks greatly, contains a large amount of micronic dusts and harmful sour gas in the tail gas of discharge, and flue gas must carry out effective desulphurization and denitration, dust removal process before discharge, to reach environment protection emission requirement.Yet along with the raising of environmental requirement, to the purification of flue gas, require also higher.It is abundant not with contacting of water that existing flue gas treatment technology exists flue gas, and dust wherein and toxic gas purify below standard just discharge, to environment.
Summary of the invention
The purpose of this utility model is exactly for existing boiler flue gas purification thorough problem, designs a kind ofly to utilize high efficiency smoke filtration post to carry out the desulphurization and denitration of boiler smoke processing, dust removal integrated plant.
For achieving the above object, the technological means that the present invention takes is, a kind of boiler exhaust gas treating apparatus with smoke filtration post, comprise that absorption tower and alkali lye prepares spray atomizing system, absorption tower comprises spray district, bottom, middle part filtering area, gentle moisture abscission zone, spray district, top, and these four treatment regions distribute from top to bottom successively; It is characterized in that: middle part filtering area is a kind of smoke filtration post, this smoke filtration post is that reverse V-shaped dividing plate arrangement forms by cross section, the inverted V-shaped dividing plate of every one deck is equidistantly arranged mutually, the inverted V-shaped dividing plate of lower one deck is between the spacing of the reverse V-shaped dividing plate of last layer, the reverse V-shaped dividing plate of adjacent two layers is staggered, and the reverse V-shaped dividing plate of same column is arranged in parallel.
The dividing plate that gas-water separation district can be V-type by the described cross section of two-layer interlaced arrangement is arranged and is formed.
The spray district, bottom on described absorption tower, middle part filtering area, gentle moisture abscission zone, spray district, top are segmentation manufacture, and absorption tower is the structure of building block system assembling.
The spray district, bottom on described absorption tower, middle part filtering area, gentle moisture abscission zone, spray district, top are segmentation manufacture, and absorption tower is the structure of building block system assembling.
Described alkali lye is prepared spray atomizing system and is comprised atomizing sprayer, alkali lye storage bin, water pump, sedimentation basin, sedimentation basin is connected with the bottom on absorption tower, sedimentation basin is connected with water pump by pipeline, water pump is connected by pipeline with atomizing sprayer, atomizing sprayer is placed in the spray district, top on absorption tower, alkali lye storage bin is placed on the top of sedimentation basin, by pipeline, is connected with sedimentation basin.
Described sedimentation basin is equipped with heater, to prevent that pool inner water from freezing.
Utilize the akaline liquid of spray head ejection to spray in spray district, top, the shock of alkali lye and Filter column produces a plurality of miniature water curtains, and liquid moisture film utilizes gravity to flow downward in Filter column, forms multilayer, a plurality of miniature water curtain in flow process.Hot-blast stove tail gas is after entering the spray district, bottom on absorption tower, in bottom, spray district sprays processing, for the first time contact and process with alkali lye, through the flue gas spraying after first processing, by bottom, up flowed, enter the Filter column of middle part filtering area, flue gas up flows and moves in Filter column, and in the running that flows, through multilayer, a plurality of miniature water curtain in Filter column, in this process, flue gas contacts and is further processed with alkali lye for the second time; Flue gas after after-treatment is through the spray district, top that enters absorption tower after Filter column, and flue gas sprays processing in spray district, top, contacts for the third time and contacts with alkali lye; Flue gas after gas after treatment enters ,Ci region, gas-water separation district and realize to purify is separated with alkali lye, and the gas after gas-liquid separation is discharged with pipeline.
The beneficial effects of the utility model are, utilize flue gas to contact with alkali lye shock repeatedly, after clashing into, in Filter column, flue gas is again through the multilayer in Filter column, a plurality of miniature water curtains, make flue gas fully contact and be mixed to form a kind of water-bath state with alkali lye, flue gas is fully contacted with alkali lye, therefore this device has two kinds of functions of clashing into desulfurization and dedusting and the dedusting of water curtain water bath desulfurization, and be added with antalkali in the spray liquid of spray system, in order to the acidic materials with flue gas, carrying out chemical neutralization reacts, thereby reach flue gas desulfurization, denitration, the object of dust removal process.
