Introduce the course of work of electric wire combustion product gases purifying processing device of the present invention below.
1, flue gas smoke abatement, dedusting and deodorisation process
The flue gas of discharging after electric wire burning enters into cyclone separator 2 under the effect of entrance centrifugal blower 1, under gravitational and centrifugal forces the big dust particle in flue gas is collected in ash bucket 9, when the dust granules in ash bucket 9 reach a certain amount of after can open bottom ash bucket 9 and released.Particle less in flue gas and gas are by the top of cyclone separator 2, caustic wash tower 3 is entered into by flue, flue gas wash away wherein most of cigarette, dirt, smelly after, the mutually isostructural water scrubber 4 with caustic wash tower 3 is entered into through flue by the top of caustic wash tower 3, flue gas remove again in water scrubber 4 a part of cigarette, dirt and smelly after, activated carbon adsorber 6 is entered into by flue by the top of water scrubber 4, and remove remaining cigarette, dirt and smelly wherein, then extracted out by vent centrifugal blower fan 7 and be discharged in air through flue.
The alkali lye spray pipeline that caustic wash tower 3 connects, carries out solid cleaning by top and side direction spray to the flue gas entered in tower after the alkali lye of tower bottom is 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 air-cooled condenser 17 pairs of circulated sprinklings to carry out pressure cooling.
Flue between water scrubber 4 and activated carbon adsorber 6 is provided with a flue path cooling de-watering system 5, external forced cooling is carried out to remove the moisture in flue gas to the flue gas flowing through this flue cross section, with a small amount of cigarette, dirt particle in the moisture that cooling stays, entered in water scrubber 4 by tapping valve 31 and participate in cleaning.
Gas sample mouth 14 on flue between caustic wash tower 3 and water scrubber 4, the gas sample mouth 38 between flue path cooling de-watering system 5 and activated carbon adsorber 6 on flue, is all arranged to manually detect flue gas mass.
2, heating activated carbon regenerative process and the vent gas treatment process that produces thereof in activated carbon adsorber
Combustion product gases is after caustic wash tower 3 and water scrubber 4, again after forcing cooling de-watering, wherein contained cigarette, dirt are few, mainly a small amount of stink, and the active carbon Main Function in activated carbon adsorber 6 is exactly cigarette to these stinks and minute quantity, dirt adsorbs.Stink is more mainly failed by the gas of complete chemical reaction, when active carbon reaches capacity state, effectively can not remove the stink in flue gas, and now carry out thermal regeneration to it.
Start in activated carbon adsorber 6 with the regenerative heater 37 from temperature-limiting device, the portion of water adsorbed in active carbon directly can drop onto the bottom of activated carbon adsorber 6, the tail gas generated after the material generation chemical reaction of absorption is extracted out by vent centrifugal blower fan 7 and flows in vent gas treatment case 8, is discharged to air after acid solution, alkali lye and washing from the gas sample mouth 46 of vent gas treatment case 8.Thermal regeneration can make active carbon restore funcitons Posterior circle utilize, and greatly reduces the consumption of active carbon, and the part pernicious gas in active carbon also can be made to be neutralized rear harmless discharge.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
