Abstract

The utility model relates to a dust and smoke cleaning device which is used for processing smoke and dust with high temperature, high humidity and causticity. The dust and smoke cleaning device comprises a spraying part and a settling basin part. When the flue gas containing smoke and dust is processed by the spraying part, the smoke and the dust are mixed with water which flows into the settling basin and are discharged out of the settling basin by a screw swedge discharging device. The utility model has high dedusting efficiency which is 90%, low cost, easy manufacture, convenient installation, convenient transportation and convenient maintenance.

Description

Apparatus for removing smoke and dust with water-mixed

A kind of boiler smoke abatement device is specially adapted to handle high temperature, high humidity and acrid dusty gas.

Domestic general smoke abatement device has the jet scrubber of establishing water injector in chimney and utilizes the eddy current place to search the sack cleaner of pouncing on flue dust at present, and the former is unsuitable for handling large-minded and the big flue gas of dust-laden particle.And volume is big, the freight height; The latter searches that to pounce on flue dust not thorough, and can not the treatment temperature height, high humidity or corrosive dusty gas.

The purpose of this utility model provide a kind of simple in structure, be convenient to installation and transportation, can the treatment temperature height, the smoke abatement device of high humidity and corrosivity dusty gas.

The utility model is achieved in that entire equipment partly is made of spray part and sedimentation basin.Its spray part is in a reciprocating type housing, and every piece housing is established a row's water spout and a screen cloth, from the ash-laden gas of air inlet introducing.Several times upset in reciprocating type housing, the liquid spraying calciferous that while repeatedly sprays through water spout, flue gas is fully contacted with water, temperature reduces, atomizing, calcium carbonate reaction in sulfur in smoke and the water generates calcium sulfite, dust granules in the flue gas suctions moisture and sinks, and enters sedimentation basin from the sewage mouth.Sedimentation basin is a rectangular channel, and the bottom is the sloping along its length, and the spiral dirt separator is housed.The sewage that flows out from the spray part enters sedimentation basin.Because the effect of several roads dividing plate that is provided with in the sedimentation basin makes sewage quiescent setting as early as possible.Dirt can be used for boiler combustion once more outside the spiral excretion machine is released the pond, eliminate secondary pollution.

The utility model is simple in structure, and is easy to manufacture, installs, transportation, maintenance be all very convenient, and cost is also lower, but good dedusting effect can handle high temperature, high humidity and corrosivity dusty gas, and can eliminate sulfur dioxide gas, and do not produce secondary pollution.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is the utility model spray part-structure schematic diagram.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is that the A-A of Fig. 1 analyses and observe.

Fig. 4 is the utility model sedimentation basin part-structure schematic diagram.

Fig. 5 is that the A-A of Fig. 4 analyses and observe.

Fig. 6 is that the B-B of Fig. 4 analyses and observe.

In conjunction with the accompanying drawings 1,2,3, spray part of the present utility model comprises a reciprocating type housing 8 of W shape, it has four road spray section, row's (desirable 10) water spout 3 all is equipped with in the top of each section, screen cloth 4 of weldering is adorned a dividing plate 13 and two screen packs 9 in the bottom of a nethermost screen cloth 4 below every row's water spout, and gas approach 1 is arranged at housing 8 tops, exhanst gas outlet 11 is arranged at the bottom, and outlet of sewer 10 is arranged at the bottom.Hot flue gas enters in the housing 8 from import 1, run into the water smoke calciferous of the first road water spout, 3 ejections, water is heated becomes the water vapour state, lump together with flue dust, increased the weight of soot dust granule, reduced flue-gas temperature, change the second road water spout 3 over to behind screen cloth 4, the effect of screen cloth 4 is that the flue dust of decline is difficult for is return.Through second, third, behind the 4th road spray, flue gas is back and forth upset several times, fully contact with water spray, soot dust granule also absorbs water and reaches full water state, along with current flow to outlet of sewer 10 smoothly through dividing plate 13, the calcium carbonate reaction that contains in sulfur in smoke and the water spray generates calcium sulfite, and flue gas passes through the filtration of screen pack 9, enters chimney from exhanst gas outlet 11 and is discharged into atmosphere.The 12nd, switch.

In conjunction with the accompanying drawings 4,5,6, sedimentation basin of the present utility model partly comprises pool wall 14, be contained in the sewage inlet pipe 15 of pool wall one end, gap 16, the horizontal three road dividing plates 18 that are contained in the pond, the screen pack 17 on dividing plate top, water supplement port 19, gap 16, the circulating water outlet 20 that the pool wall other end is equipped with, the spiral dirt separator 21 at the bottom of the pond.Spiral dirt separator 21 is installed on the bearing 22, and screw rod 24 rotates in bearing 25.The limewash or the sulfide lime emulsion of adding 10% in the pond, lime is added to the central dividing plate place, and the water calciferous that will clarify by delivery port 20 pumps into the spray part.At the bottom of the sewage that flow out the spray back enters the pond from sewage inlet, because the effect of dividing plate 18, it is tranquil that the pond keeps, sediment enters the inside of dirt separator 21 by opening 23 places of spiral dirt separator 21, screw rod by driven by motor is progressively released sediment outside the pond, and sediment can be sent into boiler and rekindle.

The utility model dust removing effects is good, proves after testing, and this equipment has produce effects to the ratio that reduces carbon monoxide, sulfur dioxide in the flue gas, and its efficiency of dust collection surpasses 90%, and the flue dust blackness is lower than the Lin Geman one-level.
