Discussion on Application of Waste Gas Treatment System in.Polypropylene Pelleting Unit
Volatile organic compounds(VOCs)have great harm to human health and climate environment,which covers a wide range of substances and involves many fields.Industrial VOCs prevention and control is the primary task of air pollution control in China at this stage,the industrial production of polypropylene is one of the sources of volatile organic compounds,in the process of producing polypropylene by gas-phase fluidized bed,the volatile gas produced by resin entering the extruder section after purification is directly discharged into the atmosphere through the vent valve at the upper part of the discharge hopper,which causes environmental pollution.In order to meet the low carbon emission standards,the existing process will be reformed,the production technology will be upgraded,and the volatile gas will be centrally treated.In the extrusion pelleting section of polypropylene production,exhaust gas collection and discharge device is installed on the upper part of the hopper under the extrusion machine.The volatile gases generated by the resin and additives are collected and put into the RCO system before entering the extrusion machine for melting,extrusion and granulation.The volatile gases are discharged into the atmosphere after burning in the RCO system to meet the standard,avoiding the emission of volatile organic compounds in the atmosphere.The reduction of environmental pollution also saves the expenditure of sewage collection fees.
