Abstract
The utility model discloses a horizontal-type cylindrical filter-bag dust remover, at least comprising a cylindrical housing provided with open channels at the both ends, wherein the open channels at the both ends are an air inlet channel and an air outlet channel respectively; a filter bag frame is arranged in the housing, and a filter bag is hung on the filter bag frame; a corresponding blowing device is arranged above the frame and the filter bag; and an ash scraping device and an ash outlet are arranged on the bottom of the housing, and an ash conveyer is arranged below the ash outlet. The horizontal-type cylindrical filter-bag dust remover disclosed by the utility model is closely matched with a steel-making production craft, and the occurrence times of the explosion venting phenomenon of the dust remover are reduced by additionally arranging explosion venting valves at the air inlet channel and the air outlet channel, thus greatly reducing influence on converter production; the filter unit of the horizontal-type cylindrical filter-bag dust remover disclosed by the utility model uses the filter bag, and the emission concentration is not greater than 10 mg/NM<3>, so that the purification efficiency is higher. According to the utility model, the filter-bag dust remover is used for replacing an electric dust remover, so that the power consumption of dust removal is reduced, maintenance is convenient, control requirements are low, and operating cost is low.
Description
Technical field
The utility model relates to a kind of deduster, relates in particular to a kind of horizontal cylinder bag dust collector that is suitable for dry dedusting of converter.
Background technology
What present dry dedusting of converter adopted usually is the electrostatic precipitator scheme.But since the operation principle of electrostatic precipitator, the blast characteristics of coal gas, and the periodicity of converter production etc., cause that easily electric cleaner " venting of dust explosion " phenomenon occurs, thereby the production of converter is impacted.Electric cleaner equipment of itself cost is high in addition, the fabrication and installation precision prescribed is high, also needs to dispose a cover high voltage source, and high voltage source is very large on the dust removing effects impact, and control operation requires all higher.Therefore from improving the development trend of converter production capacity and dedusting technology, bag dust collector is a kind of extraordinary choice direction.
The utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of horizontal cylinder bag dust collector, reaches security and the higher purpose of efficient in the dust removal process.
For achieving the above object, a kind of horizontal cylinder bag dust collector described in the utility model comprises that at least two ends are provided with the cylindrical housing of open channel, and its both ends open passage is respectively air intake passage and air-out passage; Be provided with filter bag frame in described shell, described filter bag frame is hung oneself and is provided with filter bag; Above framework and filter bag, be provided with corresponding blowing device; Be provided with at described outer casing bottom and scrape apparatus for ash and ash hole, described ash hole below is provided with cinder conveyer.
Preferably, described air intake passage and air-out passage place are equipped with safe explosion venting valve.
Preferably, the described apparatus for ash of scraping is the fan-shaped apparatus for ash of scraping, and this is scraped apparatus for ash and rotates centered by the shell axis in the enclosure, and its scraping sheet edge and outer casing inner wall are pressed close to.
The beneficial effects of the utility model are:
1, the utility model and STEELMAKING PRODUCTION handicraft close fit by adding explosion venting valve at outlet and inlet passage place, reduce deduster venting of dust explosion phenomenon and send, and greatly reduce the impact that converter is produced;
2, filter element of the present utility model adopts filter bag, and concentration of emission is not more than 10mg/Nm
3, so that purification efficiency uprises;
3, the utility model replaces electric cleaner with bag dust collector, reduces the dedusting power consumption, and is easy to maintenance, and control requires low, and operating cost is low.
Description of drawings
Fig. 1 is the structural representation of the described horizontal cylinder bag dust collector of the utility model embodiment;
Fig. 2 is the side view of Fig. 1.
The specific embodiment
Below in conjunction with Figure of description the utility model is further described.
What present dry dedusting of converter adopted usually is the electrostatic precipitator scheme.But since the operation principle of electrostatic precipitator, the blast characteristics of coal gas, and the periodicity of converter production etc., cause that easily electric cleaner " venting of dust explosion " phenomenon occurs, thereby the production of converter is impacted.Electric cleaner equipment of itself cost is high in addition, the fabrication and installation precision prescribed is high, also needs to dispose a cover high voltage source, and high voltage source is very large on the dust removing effects impact, and control operation requires all higher.Therefore from improving the development trend of converter production capacity and dedusting technology, bag dust collector is a kind of extraordinary choice direction.
For the problems referred to above, as illustrated in fig. 1 and 2, the described a kind of horizontal cylinder bag dust collector of the utility model embodiment comprises that at least two ends are provided with the cylindrical housing 3 of open channel, and its both ends open passage is respectively air intake passage 1 and air-out passage 2; Be provided with filter bag frame 5 in described shell, described filter bag frame 5 is hung oneself and is provided with filter bag 6; Above framework and filter bag, be provided with corresponding blowing device 4; Be provided with at described outer casing bottom and scrape apparatus for ash 8 and ash hole, described ash hole below is provided with cinder conveyer 9.Wherein, the described apparatus for ash of scraping is the fan-shaped apparatus for ash of scraping, and this is scraped apparatus for ash and rotates centered by the shell axis in the enclosure, and its scraping sheet edge and outer casing inner wall are pressed close to.Because coal gas of converter belongs to inflammable and explosive medium, therefore be equipped with safe explosion venting valve 7 at described air intake passage and air-out passage place, thereby guaranteed the security reliability of deduster operation.
Operation principle of the present utility model is: coal gas of converter enters in the shell in air intake passage, coal gas is through filter bag, and by the blowing device above the filter bag, so that the coal gas dust of filter bag filtering drops to outer casing bottom, for the dust that is overlying on the outer casing bottom inwall, can scrape that apparatus for ash scrapes and drop in the cinder conveyer from ash hole by fan-shaped, be transported to the corresponding position by cinder conveyer.
More than; it only is preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
