1. Overview of waste gas from plastic granulation

Plastics belong to organic substances. During the plastic granulation process, organic waste gas pollutants harmful to the environment occur, including recycling and processing of waste plastics, clear recovery and destruction of all kinds of waste plastics, high-temperature melting, filtering and extrusion, etc., all of which discharge waste gas and flue gas in varying degrees.

Hazards of waste gas from plastic granulation

During the processing of plastic particles, heating is required, which leads to the evaporation of plastic particles. Plastics themselves are refined from petroleum. Carbon and nitrogen compounds have some impurities, such as heavy metals, mercury, mercury, lead, and carbon oxides, which are harmful to people's bodies. Most of them are slowly poisoned, affecting people's hematopoietic system and respiratory system.

How does vinyl chloride, the monomer used to produce PVC in plastic factories, or ethylene, the monomer of polyethylene, come out with the exhaust gas? Ethylene is a kind of plant hormone, which can promote the ripening of plant fruits, and in case of excess, it will lead to defoliation and even death of plants. It will cause disasters to the surrounding vegetation. If the plants are gone, the rest will be a thing of the past. Of course, there are a lot of emissions from the plastic factory. If the substances contained in it can alleviate the surrounding plants, it will certainly affect the surrounding plants, even kill them.

2. Waste gas treatment process of plastic granulation

In the production process of plastic granulation plants, there will be pungent odor, and photolysis purification equipment plays a significant role in deodorization. Therefore, this equipment is widely used in various industries that will need deodorization. Hydrogen chloride, methyl methacrylate, styrene and other components in the exhaust gas are differentiated by the high-energy and high ozone ultraviolet beam, and then oxidized with ozone, so that the odor gas substances can be degraded into low molecular compounds, water and carbon dioxide, and then discharged into the atmosphere through the exhaust duct.

UV photolysis purification equipment is used to deodorization and purification treatment of medium and low concentration, atmospheric volume, and different odor gas substances, without adding any substances to participate in chemical reaction, without any mechanical action, noise, special management and daily protection, odor gas does not need special pre-treatment, such as heating, humidifying, etc. The equipment occupies a small area and has light weight. In addition, it is also used in sewage treatment plants, garbage treatment stations, paint spraying, pharmaceuticals, leather, pesticides, paper making, printing, tobacco, chemical plants, fertilizer plants, rubber plants, oil refineries, feed plants, food, breeding and other industries.
