Abstract
An industrial gas dedusting and desulfurizing device belongs to the dedusting field, and comprises a case body and a gas inlet pipe. The industrial gas dedusting and desulfurizing device is characterized in that the case body is provided with a water inlet pipe, a water outlet pipe and a gas outlet pipe; an absorption filtration layer is arranged inside the case body; the end of the gas inlet pipe is inserted in the adsorption filtration layer. The industrial gas dedusting and desulfurizing device has the advantages that the pressure of gas blown from the gas inlet pipe is significantly reduced due to the blowback action of a blowback cylinder, thus increasing the contact area of fume and the absorption filtration layer so that the fume enters the absorption filtration layer container water smoothly and uniformly; the absorption filtration layer containing water can well remove fine ash in the fume. In addition, as small clearance exists between particles in the absorption filtration layer containing water, no bubbles are formed when the fume passes through the absorption filtration layer. The fume completely touches water when the fume passes through the absorption filtration layer, and sulfur in the fume is fully absorbed by water.

Summary of the invention
In order to overcome the drawback of prior art, the invention provides a kind of industry gas dust removing desulfurizing device, can well remove dust tiny in the flue gas and sulphur, and cost is very low.
The technical solution adopted for the present invention to solve the technical problems is: design a kind of industry gas dust removing desulfurizing device, comprise casing, air inlet pipe, it is characterized in that being installed on the casing water pipe, outlet pipe and escape pipe, the adsorption filtration layer is set in the casing, and insert in the adsorption filtration layer end of air inlet pipe.Air inlet pipe connects back-blowing device, and the gas passage is set in the back-blowing device, and insert in the adsorption filtration layer end of gas passage.The flue gas that air inlet pipe contains dust is oppositely entered the adsorption filtration layer by the back-blowing device effect.At this moment, the air pressure of flue gas reduces greatly, can flow to the adsorption filtration layer lenitively, and the time that flue gas passes through in the adsorption filtration layer is long, and dust in it and sulphur can be adsorbed filter course and adsorb effectively.Wherein, back-blowing device adopts anti-inflator, forms the interlayer chamber between anti-inflator and the air inlet pipe, and insert in the adsorption filtration layer lower end of anti-inflator, offers passage on air inlet pipe, and described passage is connected with the interlayer chamber.
The present invention adopts the structural design of anti-inflator ladle cover in the periphery of air inlet pipe, can form the gas passage between anti-inflator and the air inlet pipe.In casing, be provided with can be in casing the shower nozzle of adsorption filtration layer water spray, shower nozzle connects water inlet pipe.By in the adsorption filtration layer, spraying water, the sulphur in the dust flue gas can be absorbed.
Waste water behind the absorption over cure can be discharged by outlet pipe, and waste water contains absorption filtering material.In order to prevent that these absorption filtering materials from flowing out.Guard is set in casing, and guard is between adsorption filtration layer and outlet pipe.Because the existence of guard makes absorption filtering material not flow out casing with water.
The beneficial effect that the present invention had is:
1. owing to be provided with the adsorption filtration layer in casing, insert in the adsorption filtration layer end of air inlet pipe.Thereby the most of dust in the industrial gasses is adsorbed filter course and fully absorbs.
Since in casing, be provided with can be in casing the shower nozzle of adsorption filtration layer water spray.Moisture adsorption filtration layer can well be removed the fine dusts in the flue gas, and the sulphur in the flue gas is fully absorbed.
3. owing to form the interlayer chamber between air inlet pipe and the anti-inflator, insert in the adsorption filtration layer lower end of anti-inflator.The gas that contains dust is under the effect of anti-inflator and oppositely enter the adsorption filtration layer.At this moment, the air pressure of flue gas reduces greatly, can increase flue gas and adsorption filtration layer contact area, makes flue gas steadily enter moisture adsorption filtration layer uniformly.The time that flue gas passes through in the adsorption filtration layer is long, and dust in it and sulphur can be adsorbed filter course and adsorb effectively.
Since moisture adsorption filtration layer in particle between depositing very little gap, flue gas by the time can not form bubble, flue gas contacts with water by the adsorption filtration layer time fully, fine dusts in the flue gas and sulphur are fully absorbed.
