PVC dipping is a process of uniformly spraying plastic powder onto metal to form a layer of plastic film, or heating the dipping solution and placing it into the metal to cool it down, and then wrapping the plastic on the metal surface.
According to whether heating is required, it can be divided into hot-dip molding and cold dip molding. According to the raw materials used for PVC dipping, it can also be divided into liquid dipping and powder dipping.
What are the waste gases generated during the processing of PVC plastic raw materials?
Aldehydes, alcohols, benzenes, ketones, and other substances are available in various types. Without protective measures, they can cause great harm to the human body. UV photolysis purifiers can be used for treatment, and masks should be worn during production.
Activated carbon adsorption tower device is a high-efficiency, economical and practical purification and treatment device for organic waste gas; It is an environmentally friendly equipment product that filters and adsorbs odors from exhaust gas. Activated carbon adsorption tower has the advantages of high adsorption efficiency, wide applicability, easy maintenance, and the ability to simultaneously treat various mixed exhaust gases.
An air hood can be used to collect the exhaust gas from the escape point, and after adsorption and purification by an activated carbon adsorption tower, it can be discharged outdoors through a 15 meter high exhaust chimney.
Condensation method: Using a condensing agent to condense oil and gas through a heat exchanger, most of the oil vapor will be condensed into liquid form, while air can be discharged through ventilation openings to achieve separation. This method has simple process, good safety performance, relatively low cost, small footprint, easy maintenance, low operating costs, and the recovered hydrocarbon liquid does not contain impurities.
Adsorption method can be used as one of the ways to purify the workshop environment: the exhaust gas is not discharged outside, and in general, it can recover the investment cost within six months to two years. It is also beneficial for maintaining the workshop environment, temperature, and humidity, and is energy-saving and environmentally friendly.
