Description

The wet method fume purifier

The utility model belongs to a kind of smoke and dust purifier, particularly a kind of wet method fume purifier.

Along with development of modern industry, industrial waste gas is on the rise to the pollution of atmosphere, and people's living environment has been constituted very big threat, and therefore, the requirement that country administers atmosphere is also more and more higher.Cleaner of the prior art has many kinds, as cyclone dust collector, electrostatic precipitator and hydrofilter or the like.Cyclone dust collector adopts the method for centrifugation to carry out dust removal process, and it makes dust-contained airflow in the inner rotation of whirlwind by guider, under action of centrifugal force, reaches dust purpose separated from the gas.The problem that this deduster exists is, low, the weak effect of efficiency of dust collection, and, can only the particulate material in the flue gas be separated, and can not remove pernicious gas in the flue gas, as the SO in the fire coal boiler fume ₂And NO _XOr the like.In addition, the floor space of this deduster is bigger, and surrounding environment is also had bad influence.Electrostatic precipitator is to utilize effect of electric field to make the dust in the dusty gas separated from the gas, realizes the effect of dedusting.It is made of electric field and transformation rectification two parts, and electric field then by forming as the shell of anode and the cathode line in the shell, is perhaps combined by a plurality of positive plates and many cathode line.It utilizes the formed negative pressure of natural height of electric field to extract dusty gas out, has replaced blower fan, therefore, has saved blower fan and pipeline, has reduced floor space.But, this deduster can not be removed the pernicious gas in the flue gas, can only remove the graininess dust in the dusty gas, therefore, it only is suitable for handling the gas that only contains the graininess dust, as the waste gas that produces in the cement production process, and be not suitable for handling the flue gas that contains multiple pernicious gas.Hydrofilter is that a kind of water that utilizes carries out the cleaner of purified treatment to flue gas, and it can make graininess dust and gas in the flue gas be separated, and the pernicious gas in the flue gas is purified.As " SZC/G hydrofilter " that cleaner factory in Jinzhou City's makes, it mainly is made up of housing, water tank, settling tank, precipitation pond etc., has air inlet in a side of housing, and the upper end of housing has the gas outlet.Ash-laden gas enters through impulse chamber from air inlet with the speed of 18～20 meter per seconds and enters the precipitation pond, and when impacting the water surface, bigger grit falls into the precipitation pond, and flue gas impacts diffusion, contact cohesion through S type nozzle passage, makes flue gas and water mixing sedimentation.Though this deduster can make most fine grits sneak in the water; and has certain desulfidation; but since gas and water can not reach sufficient contact thereby; the effect of dedusting is also unsatisfactory; in the gas after processing; still contain certain dust and flue gas, desulfuration efficiency only is about 70%.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and Wet-way dust-collector is improved, and a kind of efficiency of dust collection height, wet method fume purifier that desulfurized effect is good are provided.

The utility model is achieved in that

It has a housing, air inlet and gas outlet are arranged on the housing, the misty rain device is housed in housing, described misty rain device has one by motor-operated turning cylinder, several water-throwing disks are housed on the turning cylinder, sparge pipe is housed between water-throwing disk, water-throwing disk is smashed the globule of sparge pipe ejection and is dished out, in the passage that flue gas flows through, form the misty rain purifying area, flue gas is carried out purified treatment.

The utility model compared with prior art has following advantage:

1, the misty rain device is installed in housing, the globule is smashed refinement, and in housing, form the intensive strong horizontal misty rain of multilayer, this misty rain fully contacts with the vertical flue gas that passes through, therefore, and good dedusting effect of the present utility model, efficiency of dust collection can reach 100%, the flue gas clearance reaches 65～75%, and desulfuration efficiency is 98%, and the flue gas that contains a large amount of dusts and pernicious gas really is purified.

2, the scope of application is wide, and the utility model is not only applicable to the smoke abatement and dust control of various Industrial Boilers and the desulfurization of flue gas, also is applicable to the treating flour dust of other Industrial Stoves.

3, rational in infrastructure, compact, floor space is little, is convenient to construction and installation, and the complete machine cost is low.
