喷漆房对于废气处理的各种方法

来源:http://www.educneves.com/   发布时间:2018-12-27 15:27:26
1、对油性漆而言:携带油漆微粒的水珠;水性漆而言:溶解了油漆的微粒水珠;
1. For paints: water droplets carrying paint particles; for waterborne paints: water droplets dissolving paint particles;
2、弥漫在空气中的油漆微粒;
2. Paint particles diffused in the air;
3、气化状态下的油漆自身的原材料异味、稀释剂(常温漆固化剂)发出的异味、以及在反应及固化过程中释放的异味。
3. The odor of raw materials, the odor of diluent (room temperature paint curing agent), and the odor released during the reaction and curing process.
所以结合以上三种物质,商场上有多种废气处理办法,如:
Therefore, combined with the above three substances, there are many ways to deal with waste gases in shopping malls, such as:
1、喷漆废气治理——水喷淋法
1. Treatment of Paint Exhaust Gas-Water Spraying Method
原理是经过将水喷洒废气,将废气中的水溶性或大颗粒成分中的部分沉降下来,到达部分污染物与洁净气体别离的目的。但仍有部分废气中的水溶性或大颗粒成分被从顶楼排放。此法虽经济适用,但不能去除全部漆雾,更不能到达去除异味的作用。
The principle is to separate some pollutants from clean gases by spraying water on the exhaust gas and settling down part of the water soluble or large particles in the exhaust gas. However, some of the water-soluble or large particulate components in the exhaust gas are discharged from the top floor. Although this method is economical and applicable, it can not remove all the paint fog, let alone odor.

2、喷漆废气处理——uv光催化氧化法
2. Treatment of Paint Exhaust Gas by UV Photocatalytic Oxidation
利用uv紫外线光束分化有机废气是一种最有用的工业处理手段。光催化氧化法经过光分化+催化剂+活性氧离子净化三效合一的处理方式,可以最大程度将喷漆废气分化成水和二氧化碳低分子化合物,除臭作用高达99%。该法工艺简略、设备出资少,且能耗与运行成本低,适合对喷漆废气的治理。
Differentiation of organic waste gases by ultraviolet (UV) light is one of the most useful industrial treatment methods. The photocatalytic oxidation process, which combines photo-differentiation, catalyst and active oxygen ion purification, can differentiate the paint exhaust into water and carbon dioxide low molecular compounds to the greatest extent, with deodorization effect up to 99%. The process is simple, the investment of equipment is small, and the energy consumption and operation cost are low. It is suitable for the treatment of paint exhaust gas.
3、去异味——活性炭吸附法
3. Deodorization-Activated Carbon Adsorption Method
活性炭吸附选用新型活性炭,该活性炭比表面积和孔隙率大,吸附能力强,具有较好的机械强度、化学稳定性和热稳定性,如选用双层吸附,使有机废气经过与活性炭触摸,废气中的有机污染物被吸附在活性炭表面,从而从气流中脱离出来,到达净化作用。从活性炭吸附床排出的气流已达排放标准,空气可直接排放。
Activated carbon is a new type of activated carbon, which has large specific surface area and porosity, strong adsorption capacity, good mechanical strength, chemical stability and thermal stability. For example, double-layer adsorption is used to make organic waste gas touch with activated carbon, and organic pollutants in waste gas are adsorbed on the surface of activated carbon, thus separating from the airflow and reaching purification effect. The air discharged from the activated carbon adsorption bed has reached the discharge standard, and the air can be discharged directly.
