1、吸收设备
1. Absorption equipment
吸收法采用低挥发或不挥发性溶剂对VOCs进行吸收,再利用 VOCs和吸收剂物理性质的差异进行分离,光氧催化设备含 VOCs的气体自吸收塔底部进入塔内,在上升过程中与来自塔顶的吸收剂逆流接触 ,净化后的气体由塔顶排出,该工艺适合于VOCs浓度较高,温度较低的气体净化,其他情況下需要作相应的工艺调整。
The absorption method uses low volatilization or non volatile solvent to absorb VOCs, then separates the physical properties of VOCs and absorbents, and the light oxygen catalyzing equipment enters the tower at the bottom of the gas self absorption tower containing VOCs, and is in contact with the absorber from the top of the tower during the rising process, and the purified gas is discharged from the top of the tower. This process is suitable for purifying the gas with high VOCs concentration and low temperature. In other cases, the corresponding process adjustment is required.
2、吸附设备
2. Adsorption equipment
光氧催化设备在用多孔性固体物质处理流体混合物时,流体中的某已组分或某些组分可被吸表面并浓集其上,此现象称为吸附。吸附处理废气时,吸附处理废气时,吸附的対象是气态污染物 ,气固吸附。被吸附的气体组分称为吸附质,多孔固体物质称为吸附剂。
When a photocatalyst is used to treat a fluid mixture with a porous solid substance, a certain component or some component in the fluid can be absorbed and concentrated on it. This phenomenon is called adsorption. Adsorption treatment of waste gas, waste gas adsorption, the adsorption of the object is gaseous pollutants, gas solid adsorption. The adsorbed gas components are called adsorbents, and porous solids are called adsorbents.
3、有机废气的燃烧及催化浄化设备
Combustion and catalytic purification equipment 3, organic waste gas
燃烧法用于处理高浓度 Voc与有恶臭的化合物很有效.其原理是用过量的空气使这些杂质燃烧,大多数生成二氧化碳和水蒸气.可以排放到大气中.但当处理含氢和含硫的有机化合物时燃烧生成产物中需要对燃烧后气体进一步处理。
The combustion method is effective in treating high concentration Voc and stinky compounds. The principle is that these impurities are burned with excessive air, most of which produce carbon dioxide and water vapor. It can be discharged into the atmosphere. But the combustion generation products of the organic compounds containing hydrogen and sulfur need to be further treated with the combustion gas.
