Abstract
本实用新型是一种电石粉尘收尘装置,包括引风机(3)、排烟筒(1)、电弧炉烟筒(9)、供水泵(8),在排烟筒和电弧炉烟筒之间通过管道连接有半干式粉尘回收装置,该装置包括换热夹套(7)、喷水加湿器(6)和多管旋风除尘器(4),多管旋风收尘器并排设置有两个。本实用新型收集的粉尘呈半干态,清理和运输方便,又不会造成二次污染,经初步测试,收尘效率达到95%,烟气中有害气体含量降低50%。
The utility model is a dust collecting device for calcium carbide dust, which comprises an induced draft fan (3), a smoke exhaust pipe (1), an electric arc furnace chimney (9), and a water supply pump (8). There is a semi-dry dust recovery device, which includes a heat exchange jacket (7), a water spray humidifier (6) and a multi-pipe cyclone dust collector (4), and two multi-pipe cyclone dust collectors are arranged side by side. The dust collected by the utility model is in a semi-dry state, which is convenient for cleaning and transportation, and will not cause secondary pollution. After a preliminary test, the dust collection efficiency reaches 95%, and the content of harmful gases in the flue gas is reduced by 50%.
Description
The utility model relates to a kind of process units of chemicals, particularly a kind of retracting device of electric arc furnaces flue gas---a kind of calcium carbide dust dust arrester installation.
A large amount of dust of discharging and pernicious gas in the electric arc furnaces flue of production calcium carbide as suitably not handling, will cause very big pollution to environment, existing processing method can be divided into two classes, one class is a dry dust removal, generally tends to bag-type dust, but because of the dust initial temperature up to 400-600 ℃, general cloth bag material is difficult to bear, the external glass acupuncture cloth bag that adopts, but it costs an arm and a leg, big because of the dust specific volume that reclaims again, particle is little, brings very big difficulty for cleaning and transportation; Another kind of is wet dedusting, adopts the water-bath spray process, but has produced sewage again with this method, has the governing problem of secondary pollution, and the one-time investment of equipment is also bigger.
The purpose of this utility model provides a kind of a kind of half dry type calcium carbide dust dust arrester installation that overcomes wet method and dry method dust defective.
The utility model is realized by following scheme:
The calcium carbide dust dust arrester installation, comprise air-introduced machine, smoke evacuation tube, electric arc furnaces chimney, supply-water pump, it is characterized in that between smoke evacuation tube and electric arc furnaces chimney, being connected with the half dry type device for recovering powder by pipeline, this device comprises heat exchange jacket, water spray humidifier and multiclone collector, and multicyclone has been arranged side by side two;
Above-mentioned water spray humidifier is airtight cylindrical shell, is useful on the needle-valve of water spray at the cylindrical shell top;
The first half of above-mentioned multiclone collector has many group cyclone dust removal pipes, and its underpart is the slag storehouse.
Operation principle of the present utility model is: the flue gas that the electric arc furnaces chimney is discharged under the effect of air-introduced machine through heat exchange jacket cooling cooled smoke wet separating in water spray humidifier, after the multicyclone soot dust granule is settled down, half-dried dust falls into the slag storehouse, because multicyclone has two side by side, can rotate scarfing cinder, not influence production.
The dust that the utility model is collected is half-dried attitude, and cleaning and convenient transportation are energy-saving and cost-reducing, can utilize waste heat heating, can not cause secondary pollution again, and through tentatively test, dust-collecting efficiency reaches 98%, and pernicious gas content reduces by 50% in the flue gas.
Fig. 1 is that the utility model connects and structural representation.
In conjunction with the embodiments the utility model is described in more detail below in conjunction with accompanying drawing.
Embodiment: as shown in Figure 1, this routine calcium carbide dust dust arrester installation is installed between electric arc furnaces chimney 9 and the smoke evacuation tube 1 by pipeline, one flap valve 10 is housed on the electric arc furnaces chimney, under flap valve, draw flue gas, the smoke evacuation tube end is an air-introduced machine 3, on the smoke evacuation tube muffler 2 is housed, the utility model comprises heat exchange jacket 7, water spray humidifier 6 and multicyclone 4, a plurality of tornadotron 4-1 are arranged in the multicyclone 4, its bottom is slag storehouse 5, multicyclone is arranged side by side two, water pump 8 by pipeline to heat exchange jacket 2, water spray humidifier 6 and multicyclone 6 supply water, and there is a water tank 11 on the water pump side.
Claims (3)
1. calcium carbide dust dust arrester installation, comprise air-introduced machine (3), smoke evacuation tube (1), electric arc furnaces chimney (9), supply-water pump (8), it is characterized in that between smoke evacuation tube (1) and electric arc furnaces chimney (9), being connected with the half dry type device for recovering powder by pipeline, this device comprises heat exchange jacket (7), water spray humidifier (6), multiclone collector (4), and multiclone collector (4) has been arranged side by side two.
2. calcium carbide dust dust arrester installation according to claim 1 is characterized in that above-mentioned water spray humidifier (6) is airtight cylindrical shell, is useful on the needle-valve (6-1) of water spray at the cylindrical shell top.
