Description
Technical field
The utility model relates to dedusting treating apparatus technical field, particularly relates to a kind of gas cleaning at high temperature device.
Background technology
At present under the environmental protection condition that country is new, gas cleaning at high temperature device is not only widely used in the treating flour dust in cement plant, and be widely used in nonmetallic ore micro mist field of deep, also good application prospect is had in industries such as electric power, chemical industry, metallurgy, iron and steel, its operation principle: when dust laden air enters in housing by air inlet, because air-flow is expanded suddenly, flow velocity reduces suddenly, what such particle was large borrows self gravitation to drop into ash bucket, and all the other dusts are delayed at filter bag outer wall.In order to ensure the normal operation of equipment, when the dust of filter bag outer wall detention reaches certain thickness, filtering rate reduces.For maintaining certain filtering rate and equipment resistance, adopting the cleaning such as chamber-dividing counter-blowing or pulse dust cleaning filter bag, the long-pending dust being attached to filter bag outer wall being shaken off, enters ash bucket, outside conveyer discharge machine.Wherein, mostly sack cleaner lift valve conventional is both at home and abroad to adopt cylinder to be fixed on deduster top board, cylinder rod is connected with the lifting valve plate of lower end, deduster is when processing normal temperature dusty gas, the lift valve of this version still can adapt to, but with regard to current application, deduster great majority need to process high-temperature gas, due to the lower end of cylinder and the setting position of valve body, work under all needing to be in hot environment for a long time, but when process 160 DEG C of-300 DEG C of high-temperature dusty gas, the impact of high-temperature gas on cylinder seal circle and piston ring and valve body is larger, promote and accelerate the premature aging of cylinder seal circle and piston ring, the valve plates of lift valve etc. are distortion easily, lose the effects such as the seal isolation itself played, substantially reduce the service life of lift valve, cylinder seal circle and piston ring and valve body need often to change, namely maintenance load is added, have impact on again the normal operation of bag dust collector.
Utility model content
For gas cleaning at high temperature device Problems existing in above-mentioned prior art, the utility model provides the gas cleaning at high temperature device that a kind of good seal performance, dust cleaning efficiency are high, valve body is not yielding, maintenance cost is low.
The technical scheme that problem to be solved in the utility model is taked is: gas cleaning at high temperature device, comprise housing, ash bucket below housing, housing sidepiece is provided with mutually isolated air inlet and air outlet, described air inlet is connected with filtering area by connecting ash bucket, filtering area is connected with air-purifying chamber, some filter bags and bag cage is arranged at intervals with in described filtering area, injection tube and pulse valve are set above filtering area, rotary valve is provided with between air-purifying chamber and air outlet, described rotary valve comprises valve body, valve plate, described valve plate is connected in valve body by rotating shaft and axle bed, described rotating shaft is connected with drive unit, enhanced leaktightness layer is provided with between described valve body and valve plate.
Further, the outer wall of described enhanced leaktightness layer comprises circular arc sealing, and is symmetricly set on the straight line rake at circular arc sealing two ends, and circular arc sealing is connected with straight line rake is round and smooth.
The utility model has the advantages that: 1, make the forms of motion of lift valve have rectilinear motion to change rotary motion into, the executive item of driving mechanism does not directly contact with high-temperature gas, substantially prolongs the service life of driving mechanism; 2, between valve body and valve plate, be provided with the enhanced leaktightness layer of Wear-resistant, high-temperature resistant, sealing property improves, and there will not be revotating card to wait indefinitely phenomenon; 3, combine the advantage of chamber-dividing counter-blowing and pulse dust cleaning two kinds of modes, overcome the not enough and general pulse dust cleaning dust of the chamber-dividing counter-blowing deashing intensity shortcoming such as attached again, cleaning efficiency is improved, and frequency of jetting greatly reduces.

Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, in conjunction with detailed description of the invention, the utility model is described in further detail with reference to the accompanying drawings below.
As shown in Figure 1, described gas cleaning at high temperature device, comprise housing 1, ash bucket 10(taper below housing), be provided with unloading valve 9(unloading valve below ash bucket and directly can connect conveying worm conveying dust), housing sidepiece is provided with mutually isolated air inlet 8 and is connected air intake house steward and air-out house steward respectively with air outlet 7(), described air inlet is by connecting ash bucket and filtering area, filtering area is connected with air-purifying chamber 3, some filter bags and bag cage 11(skeleton is arranged at intervals with) in described filtering area, injection tube 4 and pulse valve 2(preferred electromagnetic impulse valve are set above filtering area, control compressed air and enter filtering area), rotary valve is provided with between air-purifying chamber and air outlet, described rotary valve comprises valve body 6, valve plate 5, described valve plate is connected in valve body by rotating shaft 13 and axle bed 14, described rotating shaft (is furnished with axle sleeve, not shown in FIG., adopt soft rock ink material) be connected with drive unit, described drive unit is that motor 15(can certainly realize with crank and cylinder), enhanced leaktightness layer 12 is provided with between described valve body and valve plate, enhanced leaktightness layer adopts has flexible Wear-resistant, high-temperature resistant material (polytetrafluoroethylene (PTFE)).
Preferably, in order to realize tightening seal, the outer wall of described enhanced leaktightness layer comprises circular arc sealing 17, and be symmetricly set on the straight line rake 16 at circular arc sealing two ends, circular arc sealing is connected with straight line rake is round and smooth, wherein, the thickness of circular arc sealing is substantially equal to the thickness of valve plate, straight line rake is the 1/3-1/2 of the thickness of circular arc sealing, and the effect of circular arc sealing and straight line rake is to make valve plate prevent rotating force large or occur stuck state when rotarily opening or close.
Operation principle: 1, filter: dusty gas is entered by air inlet, when ash flue bucket, in gas, part big dust particle is separated by inertia force effect, directly fall into ash bucket, dusty gas is by entering filtering area after ash bucket, and gas is through filter bag, dust is delayed at filter bag outer surface, purified gas enters after air-purifying chamber through filter pocket mouths, and now rotary valve is opening, is discharged by air outlet; 2, deashing: along with the prolongation of filtration time, dust layer on filter bag is constantly long-pending thick, electromagnetic impulse valve is opened, now rotary valve is closed condition, compressed air, with extremely very brief time undergoes rapid expansion in upper box, pours in filter bag, makes filter bag dilatancy produce vibration, and under the effect of washing away at inverted draft, the dust be attached on filter bag outer surface is stripped and falls into ash bucket.
Above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted; although be described in detail the utility model with reference to detailed description of the invention etc.; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement; and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the scope of claim of the present utility model protection.
