CN2454016Y - Wet smoke-exhausting duster - Google Patents

Abstract

The utility model relates to a wet smoke-exhausting duster which can effectively eliminate smoke dust granules and has less electricity consumption. After the smoke dust in a burning stove enters a smoke inlet pipe, the smoke dust enters a water pool to be precipitated twice, and is washed by three washing plates for three times through that dust removing components of a distributing plate, a running water filling pipe, a once washing plate, a quadric washing plate, a thrice washing plate, etc. are arranged, and thereby, the dust removing rate of the wet smoke-exhausting duster which can effectively eliminate smoke dust granules and has less electricity consumption achieves more than 99 percent; meanwhile, due to the fact that a draught fan is arranged below the smoke inlet pipe, a smoke exhausting path is short, and therefore, the wet smoke-exhausting duster which can effectively eliminate smoke dust granules and has less electricity consumption has low electricity consumption.

Description

Wet type smoking deduster

The utility model relates to a kind of dust arrester, especially can remove the wet type smoking deduster of the particle flue dust of combustion furnace discharge.

At present, known deduster structure is to be linked by smoke-intake pipe, pond, pipe, air exhauster, and smoke-intake pipe and pipe are installed in the both sides, pond, and air exhauster is installed on the pipe.When air exhauster started, the cigarette of combustion furnace was inhaled into smoke-intake pipe, went forward side by side and arranged then to pipe into the pond precipitation, and the cigarette vapour of combustion furnace promptly discharges out of the furnace.This class deduster is because of the precipitation of combustion furnace flue dust through the pond, part particle in the flue dust is not entered pipe by submerged, thereby the soot dust granule that discharges out of the furnace reduces about 50%, but because flue dust is only through a pond precipitation, still do not have precipitated less than 0.005 micron grit in the cigarette and be discharged from outside the stove, cause the pollution of atmosphere.In addition, a kind of granite duster that Sichuan Province produces at present, it is provided with a dripping device above smoke-intake pipe, by the mode of dripping, make the particle in the flue dust obtain sedimentation.The dust removal efficiency of this granite duster reaches 99%, but its weak point is too huge and heavy, and body is up to 6-8 rice, and machine weighs 15 tons.Simultaneously, above-mentioned two class dedusters also have a common shortcoming, and promptly air exhauster all is installed on the pipe, and the smoking path is longer relatively, causes the increase of power consumption.

The purpose of this utility model provides a kind of wet type smoking deduster, and it can not only remove the particle more than 99% in the combustion furnace flue dust, and power consumption reduces 2-4 doubly than known deduster.

The purpose of this utility model is achieved in that this wet type smoking deduster is made up of smoke-intake pipe, steam outlet pipe, dust pelletizing system, cone bucket shell, water level control box and the several parts of air-introduced machine.In the cone bucket shell is the pond, and its underpart is a blowoff valve, and there is water level control box its outside, and overflow pipe is arranged on the water level control box.The two ends of cone bucket shell top cover connect smoke-intake pipe and steam outlet pipe respectively.Dust pelletizing system is positioned at cone bucket shell top all, it comprise distribution plate, the operation filler pipe, once wash away plate, secondary washes away plate and washes away the several parts of plate for three times.Distribution plate is positioned at the top cover below, and there is passage on its surface, and there is an operation filler pipe on plane on it, and hole for water spraying is arranged on the pipe, between operation filler pipe and the top cover bottom surface space is arranged.The distribution plate lower plane is that secondary washes away plate, once washes away plate and washes away the two ends that plate is positioned at distribution plate three times.Air-introduced machine is installed in the smoke-intake pipe below.Water inlet pipe is positioned at the smoke-intake pipe top.When air-introduced machine one starts, the flue dust of combustion furnace promptly is introduced into smoke-intake pipe, when flue dust arrival smoke-intake pipe end enters the pond, wash away the first time that is subjected to once washing away plate, rise forward along the curved surface that once washes away plate then, be subjected to secondary again and wash away washing away of plate, cigarette vapour enters the admission case by the pore of distribution plate then, and enter into out the vapour case along the space between operation filler pipe and the top cover, pore by distribution plate down enters for the second time the pond again, and the globule that sprays from operation filler pipe spray orifice has quickened the speed that flue gas enters the pond for the second time in the vapour case.Cigarette vapour continues to rise after entering the pond for the second time, is subjected to three times again and washes away washing away for the third time of plate, arrives at last outside the pipe of steam outlet pipe.The flue dust of combustion furnace, has passed through precipitation and three three times of washing away plate in twice pond and has washed away to outlet from the import of wet type smoking deduster, and the particle in the flue dust is nearly all precipitated and washed away, so the outer cigarette vapour of discharge pipe does not pollute environment.In addition, air-introduced machine is contained in the smoke-intake pipe below, and it is short that it draws the cigarette path, thereby power consumption is low.

Owing to take such scheme, the dust removal efficiency of the combustion furnace flue dust that process the utility model is handled reaches more than 99%, and its power consumption only is 1/3rd of like product, and the new volume of this practicality is little, simple in structure, is easy to produce.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is an oblique perspective structure chart of the present utility model.

Fig. 2 is vertical section and the cross section structural map of wet type smoking deduster embodiment.

Fig. 3 is the component relation enforcement figure of the dust pelletizing system of wet type smoking deduster.

Among the figure, 1, cone bucket shell 2, Check valve with hinged closure member.3, air-introduced machine 4, flue dust import 5, smoke-intake pipe 6, water inlet pipe 7, water level control box 8, overflow pipe 9, once wash away plate 10, secondary and wash away plate 11, wash away plate 12, distribution plate three times.13, distribution plate pore 14, operation filler pipe 15, operation filler pipe spray orifice.16, admission case 17, go out vapour case 18, steam outlet pipe 19, top cover 20, water level in water pool

In Fig. 1, water level control box (7) is positioned at cone bucket shell (1) outside, and overflow pipe (8) is arranged on the water level control box (7).The lower end of cone bucket shell (1) is blowoff valve (2).
