Description
Technical field
The utility model relates to a kind of device for dust-removal and desulfurizing, especially a kind of liquid film dust-removal and desulfurizing chimney.
Background technology
The harm that now atmosphere pollution causes the mankind and living environment thereof is huge with impact, has become common people's common recognition, and people can not have a meal for three days, but cannot three minutes no breathings, and the quality of air quality is directly connected to people's physical and mental health.CHINESE REGION large area produces serious " haze ", except the impact of weather sand and dust, pollution is mainly derived from all trades and professions in a large number to the harmful substance of having discharged in atmosphere, as: sulfur dioxide (SO2), carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), suspended particulate substance (floating dirt, depositing dust, flue dust, oil smoke etc.).Analyze after deliberation, except national resident's production, life soot emissions superposition, wherein the discharge capacity of chemical industry, thermal power plant, steel plant, automobile industry and building trade ranks prostatitis.When Yi Ge large chemical plant, thermal power plant, steel plant normally produce, in tail gas, major pollutants discharged discharge is: SO
2 ., nitre, NO
x, flue dust, dust (pm2.5-pm10), NMCH, benzene,toluene,xylene, methyl alcohol, H
2 s, CO, NH
3 deng.Discharge amount of exhaust gas reaches 1000000m
3/ h left and right.If there is security incident, reality is also environmental protection accident, and gas, solid, liquid pollutant discharge amount will be more serious.Because China process of industrialization is accelerated, although small chemical factory, thermal power plant, steel plant's discharge capacity are little, discharge smoke pollution concentration is higher, and pollutant superposition is very fast, has caused quite serious atmosphere pollution.And discharge flue gas process is substantially effectively processed, and discharge capacity is also growing on and on, and makes air quality constantly decline.
Therefore, be badly in need of providing harmful substance in a kind of effectively smoke treatment discharge, and be suitable for the liquid film dust-removal and desulfurizing chimney that large-scale industrialization discharge cycle is utilized.
Summary of the invention
The purpose of this utility model is to provide harmful substance in a kind of effectively smoke treatment discharge, and is suitable for the liquid film dust-removal and desulfurizing chimney that large-scale industrialization discharge cycle is utilized.
Basic conception of the present utility model is: this product relates to chemical plant, thermal power plant, steel plant and fire coal, fuel oil big, medium-sized and small enterprises while normally producing, the processing of the flue gas pollutant discharging in chimney tail gas.According to smoke pollution properties, select different liquid fluxs, remove SO
2 ., nitre, NO
x, flue dust, dust (pm2.5-pm10), NMCH, benzene,toluene,xylene, methyl alcohol, H
2 s, CO, NH
3 deng, to reach national atmospheric emission standard.Form a kind of allow product and chimney integrated; Liquid mist, liquid film are dedusting and desulphurization integrated; The acceleration of flue gas blower fan and flue gas are caught mist and are purified integrated; The chimney of fume emission and flue gas automatic on-line monitoring integration.Allow liquid mist, liquid film dust-removal and desulfurizing and pernicious gas, catch mist film and purify discharged gas fume, thereby reduce industrial land, be convenient to new, old chimney transformation and build, reach the object of control atmosphere pollution.The utility model is according to flue dust, dust in the flue gas of discharge, and toxic and harmful, easily by the characteristic of aqueous solvent adsorbing and removing.Take the mode that aqueous solvent regeneration cycle is used, thereby realize the decontamination process of flue gas pollutant.In the utility model solvent pump type selecting pressure, flow with Diameter of chimney, highly, nozzle diameter is relevant, how much relevant outside liquid pool is with circulating fluid volume.Exhanst gas outlet quality index adopts the liquid film number of plies to control, and increasing the liquid film number of plies is mainly to strengthen exchange area, with reference to exhanst gas outlet Quality Design.Solvent circulation processing pool size, designs according to solvent internal circulating load.After flue dust dehydration, can do the utilization of cement sanded brick, the utilization of solvent liquid regeneration cycle for the treatment of.Technical process of the present utility model is: 1, the purification process of flue gas: under blower fan draft effect, flue gas enters from chimney lower ports, by the vaporific solvent dust-removal and desulfurizing of two nozzle ejections, then the liquid film dust-removal and desulfurizing forming by ground floor and the vaporific dust-removal and desulfurizing of nozzle.Enter again the vaporific solvent dust-removal and desulfurizing of second layer liquid film and two nozzle ejections, then through the 3rd layer of liquid film and two vaporific solvent dust-removal and desulfurizings that nozzle sprays.Flue gas reaches emission abatement standard.By catching mist film, remove the free water solution in flue gas again, through blower fan, send into atmosphere, qualified discharge under the monitoring of flue gas automatic on-line.2, solvent circulation process: solvent is under the pressurized delivered of pump, deliver to each layer of nozzle and form spray film, on the 3rd layer of spray film is netted on 30 inclined-planes, degree left and right, form liquid film, flow to below half garden spout and enter the netted upper and thicker liquid film of same layer spray film formation in second layer inclined-plane.After liquid film and flue-gas dust-removing and desulfurization exchange, second layer solvent flows to below half garden spout and enters the netted upper and thicker liquid film of same layer spray film formation in ground floor inclined-plane, rich solution after liquid film and flue-gas dust-removing and desulfurization exchange enters the solution collecting funnel of bottom, from funnel, flow into the solvent cell of outside, through precipitation, regeneration, process and utilize by solvent pump pressurized circulation.Top flue gas is contacted by the outer row of outlet with the solvent after purification all the time, reach the clean-up effect of flue gas.It is little that the utility model takes up an area, reduced investment, and solvent, flue dust can recyclings, are convenient to implement, and operating cost is low.After domestic blowdown stack not up to standard transformation, can effectively solve the fog impact that atmosphere pollution and flue gas form.Be applicable to the transformation of old chimney, from entrance below in interior assembling.When also newly chimney is built, directly when building chimney, press design and assembly.
