As further improvement of the utility model, described absorbent charcoal adsorber is box body, is divided into the cuboid volume of 800mm × 300mm × 1200mm, in order to place active carbon with wire netting in the lateral cross section of casing.
As further improvement of the utility model, the top of described absorbent charcoal adsorber is provided with active carbon filler cap, and downside is provided with the outlet cap of active carbon.
As further improvement of the utility model, described chimney height is 5.0m, and bottom is provided with frequency conversion smoke exhaust fan.
Adopt roller kilns of the present utility model to burn till the treating apparatus of ceramic foam filter waste gas, its processing step comprises:
(1) the sponge flue gas in roller kilns is incorporated into high temperature firing zone as combustion air, is incorporated into again by smoke discharging pipe in the spray column of outside, upwards discharges after alkaline water neutralisation treatment from bottom;
(2) waste gas after discharging enters into high-pressure electrostatic adsorbent equipment and carries out adsorption treatment; The described adsorbent equipment that is adsorbed as produces high voltage by short circuit at collecting plate syringe needle, makes by the flue gas of this device charged rapidly, is then attracted on collecting plate;
(3) waste gas after absorption is drained in ozone photodissociation clarifier; Oxygen ionization in air can be ozone by described photodissociation clarifier, is used for decomposing the organic macromolecule that molecular weight is large, smell is strong;
(4) last, whole waste gas is by being discharged by high chimney after absorbent charcoal adsorber; Remaining a small amount of unmanageable trickle band gas odorous in waste gas, by charcoal absorption.
The sponge smoke components burning till generation due to ceramic foam filter is complicated, simultaneously with sour gas corrosion strong, therefore become the important difficult point of its fume treatment always.The utility model utilizes existing roller kilns firing foamed ceramics, and the sponge flue gas adopting kiln hood to produce is combustion air, realizes the emission-control equipment that a kind of foamed ceramics burns till generation under introducing high-temperature region production technology.Its uniqueness is to adopt kiln hood sponge flue gas (accounting for more than 90% of sponge flue gas cumulative volume) to be combustion air, introduces high-temperature region and burns; So both improve efficiency of combustion (because combustion air temperature improves and sponge flue gas is mostly combustion property organic matter), high temperature incineration sponge flue gas again.Sponge flue gas, after burning, has the features such as molecular weight is little, granularity is little, and therefore exhaust-gas treatment cost is low, effective the later stage.
By the utility model device, 4 road different process process foamed ceramicses can be adopted to burn till the flue gas waste gas of rear generation: first, in alkaline water and sour gas, and dissolve partial fume particle; Second, high-pressure electrostatic absorption produces voltage by short circuit at collecting plate syringe needle, makes by the flue gas of this device charged rapidly, and is adsorbed on collecting plate; 3rd road, oxygen ionization in air is ozone by ozone photodissociation device, the organic macromolecule that decomposable asymmetric choice net molecular weight is large, smell is strong; 4th road, after above-mentioned three road PROCESS FOR TREATMENT, a small amount of unmanageable trickle can through charcoal absorption with smell product.After above-mentioned four kinds of PROCESS FOR TREATMENT, the gas colorless and odorless of discharge (is roughly CO
2, N
xo
ydeng), reach the gas discharging requirement of national regulation completely.
In the utility model, the method process foamed ceramics combined owing to can adopt physics and chemistry burns till flue gas waste gas, spray column sprays and photodissociation purification is chemical method, Electrostatic Absorption and charcoal absorption are physical method, 4 kinds of staggered combinations of method, therefore substantially increase fume treatment efficiency, and decrease material and facility loss, reduce the cost of fume treatment.
