Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
As shown in Figure 1, a kind of high-temperature gas duster device, the top of cleaning apparatus is provided with coal gas of converter import 3 and coal gas of converter outlet 7; Housing 1 is provided with supporting seat 2, and there is the filter core of a tubular inside of fly-ash separator housing 1, and filter core is made up of inner/outer tube; Urceolus 6 is bucket shape; Inner core 8 is cylindricality, and an inner core and a vapor pipe 9 connect, and inner/outer tube can adopt high temperature materials such as intermetallic Fe-Al compound or Intermatallic Ti-Al compound; The part of the inner/outer tube of filter cylinder in enclosure interior is the screen cloth type; Be full of the particulate material of filtering usefulness in the middle of the inner/outer tube; Gas gets into inner core gas exhaust duct through particulate material by enclosure interior outside filter cylinder, ash removal equipment for flapping 13 is arranged at filter cylinder top, and lower housing portion has gas soot blower 14; The housing bottom underwater of water sealed tank 11 of submerging has scraper plate slag remover 12 in the water sealed tank 11.
In order to make whole device high temperature resistant, increase the service life, wherein case top 16 can adopt water-cooled or vaporization cooling cover plate; Inner walls is equipped with high temperature resistant, wear-resistant liner; Inner walls is equipped with snakelike water-cooled coil pipe 15;
Rapping ash down falls under gravity into the hydrolock ash discharging gear in the cyclonic separator, and the fly-ash separator lower submerged is under the water surface of water sealed tank, and the assurance air can be from the ash discharging gear fly-ash separator inside of bleeding.Get into the lime-ash of ash discharging gear, the scraper plate slag remover bottom water sealed tank strikes off.Simultaneously, water seal arrangement is as a kind of " explosion trap ", when blasting, can be rapidly pressure in the burner hearth be released in the atmosphere.
The coal gas of high temperature of dust-laden gets into housing from the coal gas of converter import tangential on top, in housing, forms the outside and is rotated down the eddy flow that the center rotates up, and under the effect of cf-and gravity, large diameter dust granules falls into housing bottom.When dusty gas was upwards cut the grain bed filter core, the dust granules of small dia was set at the inner granular bed filter of filter core and falls, and the inner core that gets into filter core top then gets into vapor pipe and gets into follow-up devices such as waste heat boiler.
Fall into the high-temperature dust of lower housing portion, cooled, through bottom water seal ash discharging gear dust is drained afterwards by the water-cooled coil pipe of housing bottom.High-temperature flue gas flows through and filters in flue and the clean room process, and the water coolant that the part heat is filtered flue and top blind flange absorbs, and water coolant has not only been protected filtration flue and top blind flange, has reclaimed the heat of coal gas simultaneously.When the dust stratification in the filter core makes gas-flow resistance be increased to a certain degree, carry out deashing to granular layer, close the gas inlet valve during deashing, open ash removal equipment for flapping, make lime-ash from the screen cloth of urceolus, fall into the housing bottom water sealed tank.Housing is provided with first access opening and second access opening can be changed, overhaul cartridge filter and deashing device.If coal gas is blasted, then carry out venting of dust explosion through the bottom water sealing groove.
The utility model adopts the principle of tornado dust collector, is provided with the high temperature resistant filter core of crossing in enclosure interior simultaneously, and filter core adopts the dust separating principle of particle, and efficiency of dust collection can reach 99.9%, has effectively solved the smart Problems of dust of coal gas of high temperature.Be arranged on inner snakelike water-cooled coil pipe and case top vaporization cooling cover plate simultaneously, this prolongs fly-ash separator in the time of the life-span, has reclaimed the heat of coal gas.
The above only is the preferred embodiment of the utility model, is not the utility model is done any pro forma restriction.To any simple modification that above embodiment did, equivalent variations, modification, improvement etc. all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
