Because of the workshop scattered rubber, plastic exhaust gas is more, into the injection mold exhaust gas treatment equipment must be collected before, so the need for gas collection system for unified treatment.
Considering the company's operating costs and the safety of the plastic exhaust treatment equipment, the core technology of the process route of this plan is to use "ventilation system (ducts, induced draft fan) + exhaust system (capture more than 98% of the tar, water vapor and dust) + deep purification module (with several catalytic combustion equipment)" to treat the exhaust gases. .
Description of the technology
(1) The collected exhaust gases enter an ionization trap. When the flue gas passes through, the dust and tar in the flue gas are ionized under the action of electric charge and move towards the charged metal wire and tube wall, losing their electric charge. Under gravity, they fall to the bottom of the ionization trap and flow out, allowing the pollutants to be degraded and removed.
(2) The collected exhaust gas enters the deep purification system. When the activated carbon adsorption is close to saturation, the activated carbon adsorption is desorbed using hot air flow, and the organic matter is desorbed out of the activated carbon. During the analysis process, the organic exhaust gas is concentrated, and its concentration is tens of times higher than the original, reaching more than 2000 ppm. The concentrated exhaust gas enters the catalytic decomposition device, and eventually turns into carbon dioxide and water. After deep purification, it is discharged through the fan chimney.
