Description
Technical field
The utility model is used for rotary kiln exhaust-gas treatment, specifically a kind of waste gas cleaning system.
Background technology
Company's production rotary kiln device, the acid waste gas produced in product burning process, dust can affect environment and the air quality of surrounding directly to outer high altitude discharge, and used reclaimer exists following problem after using:
1, MnZn ferrite material has the feature that volume is little, quality is large, brings larger difficulty to dust process.As ensured, dust collection is smooth and easy, and need the exhausting amount increasing blower fan, but the heat energy loss of rotary kiln work is comparatively large, air quantity is moderate, and parallelpiped has residual dust and piles up; And in process of production, the normal temperature of dust treatment facility pipeline reaches more than 200 DEG C, and pipeline accumulated powder cannot regularly be cleared up.
2, the nozzle of spray column is sprayed water in tower, and water source carrys out the backwater of self-loopa, has dust pollution composition granule, in the jet hole course of work, the aperture on nozzle can be blocked one by one, thus affect treatment effect in the circulating and recovering water that dust, exhaust-gas treatment facilities use.
3, the water of dust, exhaust-gas treatment facilities use, in recycling, the acid concentration of water constantly strengthens, now take architectural lime to carry out water treatment, but effect is bad, supply-water pump spoilage is higher, and the sedimentary amount of tank is very large, frequently need remove contamination, bring very large impact to production.
In summary, service ability is poor, fault is many, cannot ensure normally carrying out of production.
Utility model content
For the problems referred to above, the utility model provides a kind of waste gas cleaning system.
The utility model is achieved through the following technical solutions: a kind of waste gas cleaning system, mate with rotary kiln and use, connect the dust cleaning case of rotary kiln smoke exhaust pipe upper end, described dust cleaning case upper end connects induced duct, described induced duct upper end is range hood, described range hood connects laying dust wash-up tray, laying dust wash-up tray connects air-introduced machine and spray column by skirt to downward-extension, gas discharge outlet is offered on the top of described spray column, the bottom of described spray column sets out the mouth of a river, described delivery port is connected to precipitation cooling bay by return pipe, described precipitation cooling bay is communicated with cooling tower by aqueduct.
Dust cleaning case upper end connect induced duct, described induced duct upper end is range hood, and the dust cleaning case particularly above rotary kiln installs smoking pipeline from bottom to top, then on flue top with bell-type and this flue virtual connection.Change the use of original parallelpiped, adopt vertical pipe to receive pump drainage and put, eliminate pipeline residual dust granules thing packing phenomenon.Range hood and flue virtual connection, when upwards extracting flue gas, also mix a part in the Cryogenic air in the range hood position external world, reduce flue-gas temperature.
Laying dust wash-up tray connects air-introduced machine and spray column by skirt to downward-extension, and gas discharge outlet is offered on the top of described spray column, the bottom of spray column sets out the mouth of a river.Fume extraction is entered spray column by air-introduced machine, dust and water is discharged through delivery port by nozzle sprinkle, and the gas through purification enters air through gas discharge outlet.
Delivery port is connected to precipitation cooling bay by return pipe, and described precipitation cooling bay is communicated with cooling tower by aqueduct, can establish several precipitation cooling bays here, according to needs of production, waste water is carried out precipitation purification.
Further, water is caused sedimentation basin downwards by described cooling tower, and described sedimentation basin is communicated with the water inlet of spray column by water pump.Water through precipitation purification is back in spray column again and recycles.
Further, be provided with upper and lower two-layer spiral step formula fanning strip in described spray column, the nozzle of described spray column is arranged on the top of fanning strip, is also provided with umbrella shape plate between described nozzle and upper strata fanning strip, and described nozzle is the feed pipe of diameter 50 ㎜.Upper and lower two layers are divided respectively one group of spiral step formula fanning strip to be installed.Install a umbrella shape plate above the fanning strip of upper strata, the feed pipe that diameter is 50 millimeters directly accesses tower body top, and High-Pressure Water clashes into umbrella shape plate and forms water smoke covering upper and lower two layers of fanning strip process dust, waste gas.Adopt and process in this way, not only ensure that the stability of water supply but also achieve the optimum efficiency controlling dust, exhaust-gas treatment emission compliance.
Further, described range hood is umbrella shape.Flue gas can be extracted from flue on the one hand, on the other hand the structure of umbrella shape, the air being conducive to lowering the temperature can be sucked.
Further, described sedimentation basin side is provided with soda ash and throws in case.
Throw in case at the other soda ash that arranges of sedimentation basin, staff can therefrom regularly take out, and process the recycle-water with acidity with soda ash timing, make recirculated water remain neutral water quality, basic noresidue material after analyte process, to ensure that water pump not easily.
The utility model takes above-mentioned corrective measure to carry out, and its beneficial effect is remarkable: the utility model device structure science, and exhaust treatment efficiency is high, plays good effect to environmental protection.
