Description
Technical field
The present invention relates to a kind of deduster, particularly a kind of being used for processes the particle especially PM in industrial processes discharge flue gas
2.5bag-wet electric the compound type dust remover of the harmful substance such as subparticle, acid mist.
Background technology:
The soot emissions of industrial processes discharge are air primary pollution source, are the emphasis of environment protection treating always.Since two thousand five, China in succession increases and controls dynamics to the soot emissions of the manufacturing enterprises such as cement, power plant, metallurgy, along with the continuous renewal of the new emission standard of country is promulgated, dust emission concentration limit value is restricted to 50mg/Nm3 by original 100mg/Nm3 and is strictly restricted to 30mg/Nm3 again, and key area is strictly restricted to 20mg/Nm3 especially.This is all difficult to realize qualified discharge for the existing cleaner of the overwhelming majority.Therefore, the dust pollution of many areas or enterprise is still quite serious.
Due to the pressure of China's environmental carrying capacity; control discharge standard limit also can improve further in country; existing cleaner is faced with unprecedented pressure, and first legislations of environmental protection also has to the concentration of emission that exhaust gas and dust allows the trend reduced further: two is the potentiality deficiencies processing the trickle harmful substances such as PM2.5.Therefore, development of new, the advanced cleaner that can meet new emission standard and future strict standard more seems very urgent.
Summary of the invention:
The object of the present invention is to provide the harmful substances such as a kind of particle can effectively got rid of in flue gas, particularly PM2.5 subparticle, acid mist, reduce the bag-wet electric compound type dust remover of dust emission concentration.
Its technical scheme is: a kind of bag-wet electric compound type dust remover, comprise the exhaust dust device with bag be made up of casing, bag room, ash bucket, air inlet flue, give vent to anger flue and soot cleaning system, the Wet type electric dust-removing device be made up of housing, electric precipitation parts, air inlet, outlet loudspeaker, spray system and ash bucket, it is characterized in that: described exhaust dust device with bag and Wet type electric dust-removing device tandem are arranged, be provided with by water conservancy diversion homogenating plate and the equal wind apparatus of water conservancy diversion being arranged on the band pre electrified that the positive electrode on water conservancy diversion homogenating plate is formed in exhaust dust device with bag air inlet flue; The air inlet UNICOM of give vent to anger flue and the Wet type electric dust-removing device of described exhaust dust device with bag, baffling guider and airflow distribution device is provided with successively in the air inlet of Wet type electric dust-removing device, the top of airflow distribution device is provided with the first jet of rinse spray system, the top of electric precipitation parts is provided with the second nozzle of spray system, is provided with the 3rd nozzle of spray system above the ash bucket of Wet type electric dust-removing device.
Its beneficial effect is: exhaust dust device with bag and Wet type electric dust-removing device tandem are arranged, and before exhaust dust device with bag is arranged on Wet type electric dust-removing device, most of dust in ash-laden gas is collected by exhaust dust device with bag, flue dust after exhaust dust device with bag process, the particularly harmful substance such as PM2.5 subparticle, acid mist, then carry out process by Wet type electric dust-removing device further to collect, thus effectively improve efficiency of dust collection, reduce the concentration (soot emissions can reach below 5mg/m) of dust emission in ash-laden gas; And it is rational in infrastructure, reliable, use, easy to maintenance.
