The fine dusts also having sub-fraction to be missed shakes the high-pressure electrostatic of Integral dust catcher 60 at electrostatic precipitation Big absorption affinity (jointly acts on flue dust poly-nuclear bin 71 and desulfurization and denitrification reaction bin 62 is all adsorbed Shake on the both sides electrostatic precipitation battery lead plate of Integral dust catcher 60 in electrostatic precipitation.Releasing Electrostatic Absorption After, all dust on electrostatic precipitation battery lead plate, through desorbing-shake-come off, fall and contain bucket 59 at dust In, dust is discharged by dust output mechanism 58, and carries out harmless treatment.Flue gas after removing dust is drawing Under the effect of wind suction, enter in desulfurization and denitrification reaction room 62.A, B section desulfurization denitrification agent gas, Atomizer row 61,64 sprays in the flue gas containing harmful gas simultaneously, and desulfurizing agent and the denitrfying agent of ejection exist With flue gas through fully reaction in desulfurization and denitrification reaction bin 62, the harmful gas in flue gas is removed. Flue gas containing high humility again by demister 65 except mist technique after, enter the flue gas matter after desulphurization denitration Amount controls bin 76.In flue gas mass controls bin 76, overheated steam two-sided injection nozzle row 66 Jointly monitor with flue gas mass monitoring sensor I 75 and adjust flue gas mass at any time.The cigarette that will adjust Gas is sent to flue gas and forward purifies PROCESS FOR TREATMENT bin 77 and flue gas inversely purifies in PROCESS FOR TREATMENT bin 79. The work working medium purified is adsorbent, is by absorbent particles dispensing device 78, absorbent particles is uniform Cloth is spread on flue gas and is sent to flue gas and forward purifies PROCESS FOR TREATMENT bin 77 and flue gas inversely purifies PROCESS FOR TREATMENT storehouse Room 79 carries out purifying smoke process.Flue gas after purification whether can qualified discharge, just supervised by flue gas mass Survey sensor 80 to monitor, purify up to standard after flue gas 81 be discharged in air by clean flue gas outlet.

All power consumption controls of described flue gas purification system are equal by electrostatic precipitation electrical control cubicles, absorbent particles Even dispensing device is responsible for control with recycling operating conveying mechanism electrical control cubicles.The processes such as desulphurization denitration are equal Jointly regulated and controled desulfurization off sulfide effect by out-phase three cell controller and homophase binary control device, adjust flue gas each Item index.The recycling of adsorbent be sorted by regenerating sorbent particles separatory vessel and absorbent particles after Recycle operating conveying mechanism to complete.Kept the integrally-built balance of native system with complete by bracing frame.
