Detailed description of the invention
Below in conjunction with structural representation, the present invention is described further:
For the entity depurator of asphalt flue gas purifying, the telecontrol equipment that can be actively shed by adsorbent is installed in the depurator being provided with filter bag。Being arranged on the telecontrol equipment in depurator is train, and train installs one group or array。Train include main, take turns and plate composition raised by shovel on flexible-belt and flexible-belt。Flexible-belt can be rubber strip, conveyer belt, chain, steel wire。Or train includes drivewheel, and drivewheel raises plate equipped with shovel。The drivewheel of train by casing outside motor drive, and can according to the size of required adsorbent solid dirt field concentration, the rotating speed corresponding to motor realizes。
Described depurator has depurator shell 3, depurator shell 3 has bitumen flue gas entrance 1, adsorbent entrance 9, pure qi (oxygen) outlet 12, adsorbent outlet 7 and pressure tap 11, it is pyramidal structure bottom described depurator shell 3, telecontrol equipment is installed from bitumen flue gas entrance 1 to adsorbent outlet 7 place in pyramidal structure side, the opposite side of pyramidal structure installs vibrating device 8, bitumen flue gas entrance 1 is arranged above filter bag 10, and bitumen flue gas entrance 1 is provided with gas averaging board 2。
Adsorption method for asphalt flue gas purifying, adopt and telecontrol equipment is installed in the depurator being provided with filter bag, shed in addition actively inspired for adsorbent, so as to while forming a three-dimensional adsorbent dirt field, also being hung by the dust of generation is attached on filter bag surface, when bitumen flue gas is in the process passing through this absorption dirt field, both achieved the first time adsorption cleaning of gas-particle two-phase in space。Then under the effect of pressure reduction, exhaust gas flow direction filter bag, and in passing through by hang be attached on filter bag surface dust carried out second time adsorption cleaning。The size of adsorbent (dust) concentration of the three-dimensional adsorbent dirt field formed, can be realized by the revolution of adjustment drivewheel。Bitumen flue gas is 1.2-1.8m/s in the speed after gas averaging board, adsorbent shed concentration at 50-120g/m3In scope, the rate of filtration of filter bag is within 0.8-1.5m/min。
When using first, adsorbent is encased in depurator from adsorbent entrance 9, and load after highly used by satisfied absorption, starting train 4 drives flexible-belt (such as adhesive tape, conveyer belt, chain, steel wire etc.) 5 motions, several shovels on flexible-belt 4 are raised plate 6 and just adsorbent are constantly shed inspired, thus while forming dirt field, a certain amount of adsorbent (dust) will be had again to hang and to be attached on the inner surface of filter bag 10, when adsorbent (dust) thickness on filter bag 10 reaches after stably, namely bitumen flue gas is entered by bitumen flue gas entrance 1, it is adjusted to uniform speed airflow through gas averaging board 2, in motor process, biphase absorption is carried out with the inspired dirt field of adsorbent, move to filter bag 10 under differential pressure action simultaneously, again purified again during the dust layer on filter bag 10 surface when passing through。After proceeding to a period of time, the conglomeration dust come off from filter bag drops back into again bottom at Gravitative Loads, and the adsorbent fallen with dirt field closes in storehouse undermelting, then inspired by shedding repeatedly again, until adsorption cleaning stops。In order to the aerodynamic drag keeping depurator is stable, the vibrating device 8 being arranged on depurator shell 3 can be started when needed to depurator vibration beating, so as to large stretch of conglomeration dust comes off from filter bag, it is achieved thereby that reduce the purpose of aerodynamic drag。Tail gas after purification is exported 12 discharges by pure qi (oxygen)。And when changing adsorbent, adsorbent is then discharged by adsorbent outlet 7, pressure tap 11 is for measuring the pressure difference value of depurator and air。
Example: Jiaohe City, Jilin Province charcoal ink factory, used in the past double layer planar absorption bed depurator to administer molding and dried in the air the bitumen flue gas of material machine, and the concentration of emission after purification is 50mg/m3Below。But, its floor space (the maintenance area containing necessary) reaches 45M2,, processing flue gas flow 3000M3During/H, STRENGTH ON COKE adsorbent to be changed weekly once, need to stop production 6 hours during replacing, and wants continual the working continuously of four people to complete。And after adopting the present invention, its floor space (the maintenance area containing necessary) is only 18M2, though STRENGTH ON COKE adsorbent is also changed once weekly, but only needs a people to manipulate the dress of adsorbent, discharging opening valve when changing, and can complete in shutting down 15 minutes。
