工业企业中挥发性有机废气(VOCs)按产生来源
喷漆废气:主要成分为丙酮、丁醇、二甲苯、甲苯、乙酸乙酯、乙酸丁酯等挥发性有机化合物,主要产生于油漆喷涂等表面处理企业,常见的处理方法有油帘吸收、水帘吸收,再配合二三级的活性炭吸附等。
Spray paint exhaust gas: The main components are volatile organic compounds such as acetone, butanol, xylene, toluene, ethyl acetate, butyl acetate, etc. It is mainly generated in surface treatment enterprises such as paint spraying. Common treatment methods include oil curtain absorption, water curtain absorption, and combined with secondary and tertiary active carbon adsorption.
塑料、塑胶废气:主要成分为塑料、塑胶等粒子受热加工过程中挥发出来的聚合物单体,因塑料、塑胶组成成分较为复杂,废气中主要含乙烯、丙烯、苯乙烯、丙烯晴和丁二烯等烯烃类塑料聚合物单体,但浓度普遍较低、风量大。涉及企业主要有塑料造粒企业、化纤生产企业、注塑企业、橡胶生产企业等,处理方法主要有活性炭吸收、等离子净化等。
Plastic and plastic waste gas: The main components are polymer monomers that evaporate during the thermal processing of particles such as plastics and plastics. Due to the complex composition of plastics and plastics, the waste gas mainly contains ethylene, propylene, styrene, acrylonitrile, and butadiene, among other olefinic plastic polymer monomers, but the concentration is generally low and the air volume is large. The main enterprises involved include plastic granulation enterprises, chemical fiber production enterprises, injection molding enterprises, rubber production enterprises, etc. The treatment methods mainly include activated carbon absorption, plasma purification, etc.
定型废气:主要成分为其主要成分为醛、酮、烃、脂肪酸、醇、酯、内酯、杂环化合物、芳香族化合物。涉及的企业主要为染整企业、化纤生产企业,通常采用水喷淋处理工艺和静电吸附式处理工艺。
Fixed exhaust gas: Its main components are aldehydes, ketones, hydrocarbons, fatty acids, alcohols, esters, lactones, heterocyclic compounds, and aromatic compounds. The enterprises involved mainly include dyeing and finishing enterprises and chemical fiber production enterprises, usually using water spray treatment process and electrostatic adsorption treatment process.
化工有机废气:主要由化工企业排放产生,废气成分同化工企业设计生产的化工产品种类有较大关系,普遍会采用冷凝回收及催化燃烧技术等净化收集处理方法。
Chemical organic waste gas: It is mainly generated by the emissions of chemical enterprises, and the composition of the waste gas is closely related to the types of chemical products designed and produced by chemical enterprises. Generally, purification collection and treatment methods such as condensation recovery and catalytic combustion technology are used.
印刷废气:主要成分为油墨中挥发出来的甲苯、非甲烷类总烃、乙酸乙酯、乙醇等。涉及的企业主要为含有油墨印刷工序的企业,主要如包装品、印花等公司,一般采用活性炭吸附。
Printing waste gas: The main components are toluene, non-methane total hydrocarbons, ethyl acetate, ethanol, etc. that evaporate from the ink. The enterprises involved are mainly those that involve ink printing processes, such as packaging products, printing companies, etc. Generally, activated carbon adsorption is used.
