Characteristics of biological treatment of organic waste gas 1. It is applicable to a wide range of volatile organic compounds (VOCs) and other toxic or odorous gases, such as NH3 and H2S. Hazardous pollutants in chemical, pharmaceutical, electroplating, paint spraying, printing and other industries, as well as odor in wastewater treatment plants, composting plants and waste landfill plants. 2. High removal efficiency The removal efficiency of ordinary air pollutants exceeds 90%. 3. Low energy consumption biological reaction is carried out under normal temperature and pressure, and the energy comes from the energy generated by microorganisms using VOCs.

The methods of waste gas management in the electronic industry are diverse and selected according to different needs. Principles and characteristics of waste gas treatment equipment in the plastic plant Principles of waste gas treatment equipment in the plastic plant: 1. Waste gas treatment equipment uses special high-energy and high ozone UV light beams to illuminate odorous gases, cracking odorous gases such as ammonia, hydrogen sulfide, methyl sulfide, methyl mercaptan, carbon disulfide and styrene, sulfide H2S, VOC, benzene, toluene, xylene molecular chain structure, Under the illumination of high-energy ultraviolet beam, the molecular chain of organic or inorganic macromolecular odor compounds will be degraded and transformed into low molecular compounds, such as CO2, H2O, etc.

UV photolysis uses high-energy UV light beam to differentiate oxygen molecules in the air to produce free oxygen (i.e., active oxygen). Because free oxygen carries unbalanced positive and negative electrons, it needs to combine with oxygen molecules, and then ozone occurs. Ozone has strong oxidizability. Through ozone, organic waste gas and malodorous gas are subject to synergistic photolysis and oxidation, so that organic waste gas Odor gas substances are degraded into low molecular compounds, water and carbon dioxide. 2. The waste gas purification tower for washing method uses the neutralization method, absorption method, water washing method, etc. commonly used now, and the packed turbulent ball tower for acid-base neutralization. This equipment has a large processing ability, small resistance, and high absorption efficiency. It is a gas purification equipment widely used now. The treated gas is then separated by gas and water for dehydration treatment, and then discharged into the atmosphere through the discharge pipeline, Then reach the national emission regulations.

Previously, activated carbon adsorption was selected for rubber vulcanization waste gas, and the main treatment fields include: production of electronic components, production of batteries (batteries), pickling workshop, laboratory exhaust, metallurgy, chemical plants, pharmaceutical manufacturers, coating workshops, food and brewing, furniture production, etc. It is especially suitable for waste gas treatment of rubber vulcanization, foaming and rubber refining processes in rubber industry, tire industry, seal manufacturing enterprises, rubber and plastic industry, etc. The adsorption characteristics of activated carbon are mainly used to adsorb the waste gas of organic solvents such as benzene, alcohol, ketone, ester and gasoline. However, since the activated carbon after full adsorption is a hazardous waste, it needs to find a professional solid waste or hazardous waste treatment unit for treatment, and a hazardous waste treatment agreement needs to be signed. Therefore, activated carbon adsorption has been gradually replaced by other waste gas treatment equipment, Before understanding the rubber vulcanization waste gas treatment equipment, let's first understand in which process the waste gas mainly occurs.

When mixed dusty gases with different temperature and humidity may cause condensation in the air duct, separate systems shall be set up. Pay attention to the following points when planning the dedusting system: 1. The exhaust points of the dedusting system should not be too many, so as to facilitate the balance of resistance between the branches. If there are too many exhaust points, the large section header can be used to connect the branches. The flow rate of the regulating pipe should not exceed 3m/s. 2. In order to avoid dust deposition in the air duct, the air duct of the dedusting system should be laid vertically or askew as far as possible. When laying askew, the included angle with the horizontal plane should be greater than 45 °. If it is necessary to lay horizontally, a cleanout should be set.

It is suitable for painting, printing, adhesive and other occasions where the temperature is not high, the humidity is not high, and the exhaust volume is large, especially for the purification and recovery of halides. 2. UV light major Super oil smoke resistant purifier The UV photolysis skill is Super oil smoke resistant purifier install Using special ultraviolet wave band, the injection molding waste gas molecules are broken and their molecular chains are broken. Together, the water and oxygen in the air are decomposed into highly active ozone or free hydroxyl, and then the waste gas molecules are oxidized to generate water and carbon dioxide. The participation of catalyst can improve the reaction rate and the efficiency of treating injection molding waste gas, and then achieve the goal of purifying waste gas.
