The below introduces the course of work of electric wire combustion product gases purifying processing device of the present invention.
1, flue gas smoke abatement, dedusting and deodorisation process
The flue gas of discharging after the electric wire burning enters into cyclone separator 2 under the effect of entrance centrifugal blower 1, under centrifugal force and action of gravitation, the big dust particle in the flue gas is collected in the ash bucket 9, can be opened ash bucket 9 bottoms after a certain amount of it is emitted when the dust granules in the ash bucket 9 reaches.Less particle and gas are by the top of cyclone separator 2 in the flue gas, enter into caustic wash tower 3 by flue, flue gas therein the most of cigarette of flush away, dirt, smelly after, enter into water scrubber 4 with caustic wash tower 3 same structures by the top of caustic wash tower 3 through flue, flue gas in water scrubber 4, remove again a part of cigarette, dirt and smelly after, top by water scrubber 4 enters into activated carbon adsorber 6 by flue, and remove therein remaining cigarette, dirt and smelly, extract out and be discharged in the air through flue by vent centrifugal blower fan 7 again.
The alkali lye spray pipeline that connects on the caustic wash tower 3 carries out solid cleaning by top and side direction spray to the flue gas that enters in the tower after the alkali lye of tower bottom pumped into top.Because this process will be carried out at a certain temperature, temperature can not be too high, so need the alkali lye of 17 pairs of circulated sprinklings of air-cooled condenser to force cooling.
Flue between water scrubber 4 and the activated carbon adsorber 6 is provided with a flue pipeline cooling de-watering system 5, the flue gas in this flue cross section of flowing through is carried out external forced cool off to remove moisture in the flue gas, with a small amount of cigarette, dirt particle, enter in the water scrubber 4 by tapping valve 31 and to participate in cleaning in the moisture that stays of cooling.
2, heating activated carbon regenerative process and the vent gas treatment process that produces thereof in the activated carbon adsorber
Behind combustion product gases process caustic wash tower 3 and the water scrubber 4, again through after forcing cooling de-watering, wherein contained cigarette, dirt are few, mainly are a small amount of stinks, and the active carbon Main Functions in the activated carbon adsorber 6 are exactly that cigarette, dirt to these stinks and minute quantity adsorbs.Stink mainly is that some fail when active carbon reaches capacity state, can not effectively be removed the stink in the flue gas by the gas of complete chemical reaction, and carry out thermal regeneration to it this moment.
Start in the activated carbon adsorber 6 with the regenerative heater 37 from temperature-limiting device, the part moisture that adsorbs in the active carbon can directly drop onto the bottom of activated carbon adsorber 6, the tail gas that generates behind the material generation chemical reaction of absorption is extracted out and is flowed in the vent gas treatment case 8 by vent centrifugal blower fan 7, is discharged to the air through the gas sample mouth 46 from vent gas treatment case 8 after acid solution, alkali lye and the washing.Thermal regeneration can make behind the active carbon restore funcitons recycling, has greatly reduced the consumption of active carbon, also can make the part pernicious gas in the active carbon be neutralized rear harmless discharge.
Above-described embodiment is described preferred embodiment of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that those of ordinary skills make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
