Plastic wastewater treatment equipment
The process of regenerating waste plastics generally goes through several stages of recycling, screening, crushing, cleaning, drying, granulation, etc., due to the specificity of having a production process, it will produce three wastes. Therefore, Hebei regenerative plastic pellet machine manufacturers in the opening of the production line, the need for sewage must have a clear sewage treatment facilities, and then in accordance with the national wastewater discharge standards discharge, for the treatment of waste gas can be used to absorb organic waste gas such as activated carbon and other may be produced.
Recycled plastic pellet machine process
For directly in the raw and modified regeneration of waste plastics, the processing equipment are mainly single-screw extruder, twin-screw extruder and multi-stage pelletizer. Waste material by the extruder melt plasticization, extrusion strip material, according to the required specifications directly thermal cutting granule or cooling granulation. The extrusion pelletizing process is: extrusion pelletizing process control, raw material pretreatment, temperature control, pressure control, impurity filtration and other processes.
Pollution generated by the recycled plastic pellet machine
Pollution generated by the recycled plastic pellet machine: in general, mainly recycled waste plastic cleaning effluent, as well as chemical processing of waste gas pollution, and waste water treatment of solid waste management.
Recycled plastic pellet machine generated by most of the exhaust gas for the volatile organic exhaust and malodorous gases, the exhaust contains toxic substances, there is a clear odor. According to our experience, the composition of the exhaust gas produced by the plastics industry mainly includes non-methane total hydrocarbons, benzene, toluene, ethylbenzene, styrene, o-xylene, m-xylene, n-undecane, acetone, butanone, isopropyl acetone, ethyl acetate, butyl acetate and so on. Different plastic products industry, according to the different processing technology and raw materials, the composition of the waste gas generated are different.
In addition to exhaust gases, some plastics processing processes may be present in the presence of significant particulate matter, smoke.
Hebei regenerated plastic pellet exhaust gas treatment equipment
For the specific working conditions of regenerated plastic pellet exhaust gas treatment, we recommend targeted selection of RCO catalytic combustion device, plasma exhaust gas treatment equipment, photocatalytic exhaust gas treatment equipment, electrostatic fume and oil mist purifiers, etc., and supplemented by spraying, electric tar traps, high-efficiency filters, such as pre-treatment and post-treatment processes.
ROC catalytic combustion device purification principle: is under the action of the catalyst, the VOCs in the 200 ~ 400 ℃ low temperature conditions decomposition into CO2 and H2O, is one of the effective means of purification of hydrocarbons and other organic waste gas, eliminating the bad smell. Regenerative catalytic combustion device, referred to as RCO, is a kind of organic waste gas purification technology that combines low-temperature catalytic oxidation with thermal storage technology.
Plasma exhaust gas treatment equipment purification principle: can efficiently deal with benzene, toluene, non-methane hydrocarbons and other organic waste gas, but also efficiently deal with hydrogen sulfide, ammonia and other malodorous gases, is widely used, purification effect in line with the requirements of environmental protection waste gas facilities. As an experienced plasma exhaust gas treatment equipment manufacturers, our equipment has been successfully applied to plastics, rubber, spray paint, food processing and many other industries.
Photocatalytic exhaust gas treatment equipment purification principle: the use of special high-energy, high-ozone UV ultraviolet beams irradiation of exhaust gas, cracking the molecular chain structure of industrial exhaust gas, so that organic or inorganic polymer malodor compounds molecular chain, under the irradiation of high-energy ultraviolet beams, the degradation of the transformation of low molecular compounds such as CO2, H2O.
Electrostatic oil smoke and oil mist purifier purification principle: high and low voltage electrostatic, pure high-voltage electrostatic 2 kinds, suitable for all kinds of industrial production workshop produced by the oil smoke, oil mist.
