Widespread smog in China this year, has caused great concern in the community, has promulgated regulations to control exhaust gas smoke emissions in the industrial processes. Plastics processing in particular, recycling of waste plastics recycling process, various types of recycling of waste plastics by sorting, after washing, into the high temperature melting and filtering out the waste plastic particles, waste smoke emission, in varying degrees, became a source of secondary pollution. Plastic recycling companies, big and small, by using waste plastic particles in melting conditions arising waste smoke machine or by exhaust gas treatment equipment (except hood) filters, have been reported frequently punished or even turned off. Can be predicted with the strengthening of national environmental governance, lack of exhaust gas treatment device that eliminates the smoke machine enterprises will be fined, ordered to close down, or even revoking business licenses.
First, equipment layout. Waste plastic particles prior to its installation mainly due to water and electricity, while not ignoring concerns about discharge of exhaust gas treatment equipment, vents should be set on the downwind, and exhaust gas emissions in a timely manner. Otherwise dust may accumulate in the workshop could not be discharged, ranging from workers ' jobs, while emissions harmful to the human body for a long time.
Three points above are business in plant construction and problems in production, is the emission of exhaust gas smoke smooth preconditions. But some of the exhaust fumes is harmful in itself, not directly emitted into the air, the enterprise is equipped with appropriate exhaust gas treatment equipment, filtering through the emission of exhaust gas treatment equipment, free of pollution standards before discharge.
Second, the enterprise location. Plastic recycling companies address the best choice in the industrial park, where the first industrial zone, is the Government planning, companies can receive support, in particular, a number of policy support from the Government; Second Industrial Park enterprises are mostly high emission enterprises, the Government will have a certain emission requirements, as long as firms operate in the requirements of environmental protection, the Government would not interfere.
Third, plant construction. Waste plastic particles in the production process will inevitably produce a certain amount of exhaust gases, late in the planning workshop to take fully into account the exhaust emission problem, construction suitable for the construction of the plant on the ground downwind of the wind direction, most likely against residential areas to avoid and reduce pollution.
