Description

Exhaust treating purifier

Technical field

The invention belongs to technical field of waste gas treatment, be specifically related to a kind of exhaust treating purifier.

Background technology

Waste gas purification (Fluegaspurification) mainly pointer work that industrial waste gas such as dust granules thing, flue gas flue dust, gas with foreign flavor, toxic and harmful that industrial site produces are administered.Common waste gas purification has factory's fume and exhaust gas purifying, workshop dust waste gas purification, organic waste-gas purification, the purification of waste gas peculiar smell, acid-base waste gas purifying, purification of chemical waste gas etc.A large amount of water-soluble substanceses and its other poisonous and harmful substances non-water-soluble are comprised during waste gas is divided into.

In traditional rubbish waste gas treatment process, first will carry out Transformatin to the water-soluble substances in waste gas, traditional minimizing technology is often just sprayed by single spray equipment, makes that the water-soluble substances in waste gas is water-soluble to be removed.This method efficiency is low, and dust removal efficiency is low, has a strong impact on the subsequent treatment work of waste gas; And the temperature of waste gas is usually higher, traditional emission-control equipment lacks cooling function.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, a kind of exhaust treating purifier is provided.

The present invention is achieved by the following technical solutions:

A kind of exhaust treating purifier, comprise a tank body, the top of tank body is provided with gas outlet, alternately successively from bottom to up in the inside of tank body is provided with dividing plate, gas distributor, the first spray equipment, Pall ring filler layer, the second spray equipment; Gripper shoe is provided with below described Pall ring filler layer; Described dividing plate is horizontally fixed in inner tank wall, dividing plate is provided with a scupper, tank skin below dividing plate is provided with one and is recycled into the mouth of a river, be recycled into the mouth of a river to be connected with the second spray equipment with the first spray equipment respectively by pipeline, be provided with the first water circulating pump being recycled on the pipeline that the mouth of a river and the first spray equipment be connected with the second spray equipment; Also be provided with heat exchanger being recycled on the pipeline that the mouth of a river and the first spray equipment be connected with the second spray equipment, heat exchanger is provided with cooling circuit, cooling circuit is provided with the second water circulating pump; Tank skin between dividing plate and gas distributor is provided with at least one air inlet.

In technique scheme, the first spray equipment is provided with shower nozzle.Further, the shower nozzle quantity on the first spray equipment is 1-10.

In technique scheme, the second spray equipment is provided with shower nozzle.Further, the shower nozzle quantity on the second spray equipment is 1-10.

Advantage of the present invention and beneficial effect are:

Waste gas enters into tank interior from air inlet, then waste gas evenly upwards disperses through gas distributor, gas flow is through the first spray equipment afterwards, undertaken spraying tentatively to remove the water-soluble dust granules thing contained in waste gas by the first spray equipment, gas flow is through Pall ring filler layer and the second spray equipment afterwards, the spray liquid of described second spray equipment is sprayed onto Pall ring filler layer, Pall ring filler layer is as the mass transfer media of gas-liquid two-phase Contact, waste gas is fully contacted with spray liquid at filling surface, thus remove short grained water-soluble substances residual in removing exhaust gas further.The present invention is by two stage cycle spray equipment, and Pall ring filler layer efficiently processes waste gas, ensure that the efficient of exhaust-gas treatment, is effectively lowered the temperature to the waste gas in tank body by heat exchanger simultaneously.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Wherein: a is tank body, 1 is air inlet, and 2 is dividing plate, 3 is scupper, and 4 for being recycled into the mouth of a river, and 5 is the first water circulating pump, 6 is the first spray equipment, and 6-1 is shower nozzle, and 7 is the second spray equipment, 7-1 is shower nozzle, and 8 is gas distributor, and 9 is gripper shoe, 10 is Pall ring filler layer, and 11 is gas outlet, and b is heat exchanger, b-1 is cooling circuit, and b-2 is the second water circulating pump.

Detailed description of the invention

Technical scheme of the present invention is further illustrated below in conjunction with specific embodiment.

A kind of exhaust treating purifier involved in the present invention, comprise a tank body a, tank body is vertically arranged, the top of tank body is provided with gas outlet 11, alternately successively from bottom to up in the inside of tank body is provided with dividing plate 2, gas distributor 8, first spray equipment 6, Pall ring filler layer 10, second spray equipment 7, be provided with gripper shoe 9 below described Pall ring filler layer 10, Pall ring filler is stacked on support plate 10 with disordered fashion, described dividing plate 2 level is fixed in inner tank wall, dividing plate 2 leaves a scupper 3, tank skin below dividing plate is provided with one and is recycled into the mouth of a river 4, be recycled into the mouth of a river 4 to be connected with the second spray equipment 7 with the first spray equipment 6 respectively by pipeline, first spray equipment 6 is provided with 7 shower nozzle 6-1, second spray equipment 7 is provided with 7 shower nozzle 7-1, be provided with the first water circulating pump 5 being recycled on the pipeline that the mouth of a river 4 and the first spray equipment 6 be connected with the second spray equipment 7, (tank base is equipped with water in advance to make the water of tank base feed the first spray equipment 6 and the second spray equipment 7 by the first water circulating pump 5, the height of water is no more than dividing plate), the liquid of the first spray equipment 6 and the ejection of the second spray equipment 7 is back to tank base through scupper 3 simultaneously, also be provided with heat exchanger b being recycled on the pipeline that the mouth of a river 4 and the first spray equipment 6 be connected with the second spray equipment 7, heat exchanger b is provided with cooling circuit b-1, cooling circuit b-1 is provided with the second water circulating pump b-2, owing to entering the waste gas of tank body, often temperature is higher, so install heat exchanger additional on circulated sprinkling pipeline, and by cooling circuit, the liquid in circulated sprinkling pipeline is lowered the temperature, to prevent the follow-up exhaust-gas treatment of the too high impact of temperature in tank body, tank skin between dividing plate 2 and gas distributor 8 is provided with at least one air inlet 1, waste gas enters into tank interior from air inlet 1, then waste gas evenly upwards disperses through gas distributor 8, gas flow is through the first spray equipment 6 afterwards, undertaken spraying tentatively to remove the water-soluble dust granules thing contained in waste gas by the first spray equipment, waste gas streams is through Pall ring filler layer 10 and the second spray equipment 7 afterwards, the spray liquid of described second spray equipment 7 is sprayed onto Pall ring filler layer 10, Pall ring filler layer is as the mass transfer media of gas-liquid two-phase Contact, waste gas is fully contacted with spray liquid at filling surface, thus remove short grained water-soluble substances residual in removing exhaust gas further.The present invention is by two stage cycle spray equipment, and Pall ring filler layer efficiently processes waste gas, ensure that the efficient of exhaust-gas treatment, is effectively lowered the temperature to the waste gas in tank body by heat exchanger simultaneously.

Above to invention has been exemplary description; should be noted that; when not departing from core of the present invention, any simple distortion, amendment or other those skilled in the art can not spend the equivalent replacement of creative work all to fall into protection scope of the present invention.
