恒创环保分享:汽车维修喷漆废气处理方案

2020.2.2
 汽车维修喷漆产生的废气对工人及周边环境造成一定影响。为了满足与地方日趋严格的环保要求,应及时对此类废气进行必要治理,使废气排放总量和排放浓度达到当地环保要求,那么汽车维修喷漆废气处理​方案有哪些呢?下面恒创环保小编就来为大家进行分析。
 
 
 
 
  1、低温等离子处理法
 
 
 
  等离子体内部产生富含极高化学活性的粒子,如电子、离子、自由基和激发态分子等。废气中的污染物质与这些具有较高能量的活性基团发生反应,终转化为CO2和H2O等物质,从而达到净化废气的目的。适用范围广,净化效率高,尤其适用于其它方法难以处理的多组分恶臭、有机废气。
 
 
 
  喷漆废气特点分析:喷涂废气也就是在喷涂涂料的时候产生的废气,这些废气的主要构成成分是苯、甲苯、二甲苯以及一些粉尘颗粒等,大多数的喷涂废气还包含了乙酸乙酯、丁酮、异丙醇以及一些醚类物质。
 
 
 
  废气源→高效吸收塔(吸收掉漆雾、粉尘以及颗粒物为等离子提供优良的运行环境)→低温等离子设备(破坏废气分子结构,转化为无污染物质)→高压风机(高压的吸力作用下将风抽出车间)→洗涤塔(洗涤塔水洗小分子碎片,利于检测达标)→烟囱高空排放。
 
 
 
  喷漆废气中成分都是具有一定复杂特性,一定毒性,并且容易燃烧容易爆炸,治理的时候需要运用高压风机将喷涂废气抽到高压喷淋塔中进行预处理,然后进入低温等离子设备破坏有机废气分子结构,然后进入洗涤塔水洗破坏的小分子终排空。
 
 
 
  2、光氧催化氧化法
 
 
 
  利用特制的高能高臭氧UV紫外线光束照射废气,使有机或无机高分子恶臭化合物分子链,在高能紫外线光束照射下,与臭氧进行反应生成低分子化合物,如CO2、H2O等。适用范围广,净化效率高,操作简单,除臭效果好,设备运行稳定,占地小,运行费用低,随用随开,盖味除臭能力好,分解效果没有低温等离子好,不会造成二次污染。

The exhaust gas produced by car maintenance and painting has a certain impact on workers and the surrounding environment. In order to meet the increasingly strict national and local environmental protection requirements, it is necessary to timely treatment of this kind of waste gas, so that the total amount of exhaust emissions and emission concentration to meet the local environmental protection requirements, then car maintenance spray paint exhaust treatment scheme what? Hengchuang environmental protection below small series for everyone to analyze.
 
1. Low temperature plasma treatment
 
The plasma produces particles rich in extremely high chemical activity, such as electrons, ions, free radicals and excited molecules. The pollutants in the waste gas react with these active groups with higher energy, and finally convert into CO2 and H2O, so as to achieve the purpose of purifying the waste gas. Wide range of application, high purification efficiency, especially for other methods difficult to deal with multi-component odor, organic waste gas.
 
Spray paint exhaust characteristics analysis: spray exhaust is also produced in the spraying paint exhaust, the main components of the exhaust is benzene, toluene, xylene and some dust particles, most of the spray exhaust also contains ethyl acetate, butyl ketone, isopropanol and some ether substances.
 
Absorb the gas source and efficient absorption tower (paint mist, dust and particulate matter good running environment for plasma) and low temperature plasma equipment (destroy the molecular structure of exhaust gas, into non-polluting materials) and high pressure fan (high pressure suction, extract the wind under the action of workshop), washing tower, washing tower washed pieces of small molecule, conducive to test standard) - chimney air emissions.
 
Spray paint in the exhaust gas composition are all have certain complex features, certain toxicity, and easy combustion and explosion of governance when fan will need to use high pressure spraying exhaust smoke to pretreatment, the high pressure spray tower and then destroy the molecular structure of organic waste gas into the low temperature plasma equipment, then small molecule finally emptying into the scrubber water damage.
 
2. Photooxygen catalytic oxidation
Special high-energy high-ozone UV ultraviolet beam is used to irradiate waste gas to make organic or inorganic polymer odor compound molecular chain react with ozone to generate low-molecular compounds, such as CO2 and H2O, under the irradiation of high-energy ultraviolet beam. Wide range of application, high purification efficiency, simple operation, good deodorization effect, stable operation of the equipment, small occupation, low operating costs, with the use of open, cover odor deodorization ability, decomposition effect is not as good as low-temperature plasma, will not cause secondary pollution.
 
Spray paint exhaust characteristics analysis: spray exhaust is also produced in the spraying paint exhaust, the main components of the exhaust is benzene, toluene, xylene and some dust particles, most of the spray exhaust also contains ethyl acetate, butyl ketone, isopropanol and some ether substances.
 
Spray paint waste gas treatment technology: gas source and efficient absorption tower (absorb paint mist, dust and particulate matter good running environment for catalytic activated carbon and light) and activated carbon adsorption tower (benzene, toluene xylene adsorption part) - > photocatalytic devices (ultraviolet light molecules exhaust air to produce ozone oxidation, conducive to national standards) and high pressure fan (high pressure under the action of suction will continue pulling exhaust workshop) - high chimney emission (or a low emissions).
he above is hengchuang environmental protection waste gas treatment factory for you to introduce the vehicle maintenance spray paint exhaust treatment scheme what analysis, hope to provide you with reference.
