Abstract

A comprehensive duster able to remove SO2 is composed of a water tank, a duster unit, a draught, an air sucking cap, a water pump, a filter pool and and a water pool, and features that the substances able to react with SO2 or absorb SO2 are added to water and filter layer. Under action of the draught fan and water pump, the dust-containing gas passes through venturi, water membrane, water beating, cyclone and foam duster unit to remove SO2 and dust. Its advantages is high effect on removing dust and SO2.

Description

Wen Shi comprehensively removes SO 2Deduster

The invention belongs to the technical field that purifies air, more precisely is to remove SO ₂Deduster makes it to be up to state standards.

Belong to big flow or high temperature and remove SO ₂Deduster uses sack cleaner or electromagnetism deduster to stop up easily, also easy scaling loss when using high temperature, and the life-span of deduster also is difficult to guarantee.When using the stove deduster, the SO of furnace gas ₂Also be difficult to remove.The object of the invention provides a cover dust pelletizing system, can effectively remove various furnace cupolas, boiler, kiln, the dust SO of discharge ₂Reach the dust that national secondary discharge standard and other various forms produce and reach national grade ii standard.The name of this deduster claims Wen Shi comprehensively to remove SO ₂Deduster.

Wen Shi comprehensively removes SO ₂Deduster is made up of water tank (1) deduster (2) ventilation blower (3) clarifier (4) air draught cap (24) water pump (5) filtering ponds (6) ponds (7), Wen Shi comprehensive dust remover dust and SO under the negative pressure of air-introduced machine (3) and water-aspirator pressure effect shown in figure one ₂Sucked through Wen Shi jet pipe (10) by the mouth of pipe (8), shower water is supplied with by nozzle (9), and the dust aqueous mixtures sprays into control (11) and carries out water attack, and most of dust enters in the water tank water, all the other dust SO ₂And gas, making gas produce rotation, make the centrifugal deduster inwall that is attached to of part dust generation be poured water tank by impeller (12), gas enters filter course (13) again, produces foam at filter course, makes the thin dirt of the overwhelming majority be removed SO ₂Gas fully contacts the overwhelming majority with water and is absorbed and produces and react the generation novel substance and poured water tank by shower (14) with medium in filter course.Gas is under the suction function of air-introduced machine (3), enter the upper box of deduster (2), the moisture film that breaks through nozzle (15) enters impeller (16), impeller (16) produces rotation gas, carry out centrifugal dust-removing in pipe (17), enter air-introduced machine (3), air-introduced machine (3) is discharged gas and is entered upward inner chamber of clarifier (4), running water and rotation gas are mixed into filter course (19), further remove dust and SO in filter course ₂Superfluous water flows to the pond by the clarifier bottom.The residue aqueous vapor makes gas produce centrifugal force through impeller (20), water is separated dirty, clean gas enters air-breathing cap (23) by pipeline, upper flange (2), (3) are managed (4) up and down down, (5) are formed by blade (1) shown in figure (two), blade (1) produces eddy current and produces suction to discharging gas under the effect of upper air current, the end opening of deduster (2) is to be sealed by water tank (1).The superfluous water of water tank is to have casual water pipe (22) to flow out, and is filtered by filtering ponds (6) and flows into pond (7), and water pump is drawn into deduster (2) to water from the pond in (7) and uses.

For the corrosion the present invention who prevents the deduster inwall scribbles anti-corrosion material at deduster, water tank, clarifier pipeline, ventilation blower inwall, to prolong the life-span of deduster.

The present invention has adopted multistage dedusting method in order to make dust-exhausting quantity reach national dust discharge secondary standard.

The present invention stops up in order to prevent deduster, adopts continuous dedusting method.

The present invention is in order to make SO ₂Discharge capacity is up to state standards and does not produce pollution, puts into to absorb SO in filtering material and in the water ₂, and can not produce the secondary pollution material with the sulfur dioxide reaction.

Claims

Deduster
