**Waste Gas Treatment Equipment**

Horizontal Acid Mist Recoverer

The machine is a new acid mist recovering device. The air flow containing molecular groups of acid mist will disperse, collide, nucleate, agglomerate and settle in the device to separate liquid and gas. The recoverer features fine sealing performance, leakage proof, high recovering rate and strong age resistance etc.

Cyanogen-Containing Waste Gas Purification Tower

The equipment consists of ventilator, water pump and absorption tower. The block boards of two different media are installed in the absorption tower, (one medium is 8 layers of plastic gauze, and the other is composed by 10mm sponge and 2 layers of plastic gauze.). In addition, the rotational flow mist removal board is installed at the waste gas outlet.

The cyanogens-containing gas will be inhaled into the pipes when the ventilator is working. It will first be delivered to the first herringbone plastic gauze block layer with the positive pressure from the ventilator, and the penetrated gas will enter herringbone sponge block layer. Meanwhile, two arrays of liquid injection holes are installed on both sides of the second block layer, and the pump will inject the liquid from the bottom and spray it on the second block layer evenly. The cyanogens-containing gas has to be discharged together with the water drops or films, and the liquid should adequately contact and react with the harmful gas to eliminate it. And an additional outward rotating flow control board should be installed to prevent the liquid drop from escaping the absorption tower.

Compound Nitrogen Oxide Gas Purification Tower
The discharge feature of the equipment is explosiveness and high concentration. The normal wet absorption tower is effective in most cases, but while the outburst of gas is generated during operation, it cannot alter the spraying quantity and concentration, so the nitrogen oxides will not be completely neutralized and absorbed in time, and white or yellow smoke will occur. The previous active carbon method can fully absorb the explosive nitrogen oxides at various concentrations, and the purification rate is 98%. But when the concentration is high, the active carbon will easily saturate, and de-adsorption will be needed. In addition, the purification efficiency is lowered once the active carbon absorbs moisture, so the adsorption cycle is shortened, and the de-adsorption will be frequently needed.
Compound nitrogen oxides purification tower solves the problems of the above treatment methods. It adopts the two-stage approach that integrates dry and wet method. The combined spraying waste gas purification tower can get rid of 80% of the nitrogen oxides, and the left 20% will be dewatered in the dewatering tower, and then will enter the active carbon purifier, where it will be absorbed. The equipment has high purification rate, and the adsorption cycle and de-adsorption cycle to the same waste gas quantity will be greatly extended.
