工作原理

该活性炭吸附装置主要由活性炭层和承托层组成。活性炭具有发达的空隙,比表面积大,具有很高的吸附能力。正是由于活性炭的这种特性,它在水的深度处理中被广泛应用,如生活给水,污水后段的(净水)深度处理等。

含尘气体由风机提供动力,正压或负压进入塔体,由于活性炭固体表面上存在着未平衡和未饱和的分子引力或化学健力,因此当此固体表面与气体接触时,就能吸引气体分子,使其浓聚并保持在固体表面,污染物质从而被吸附,废气经过滤器后,进入设备排尘系统,净化气体高空达标排放。

1。吸附效率高,吸附容量大,适用面广

2.维护方便,无技术要求

3.比表面积大,良好的选择性吸附

4.活性炭具有来源广泛价格低廉等特点

5。 吸附效率高,能力强

6。 操作简易、安全

活性炭使用一段时间后,吸附了大量的吸附质,逐步趋向饱和,丧失了工作能力,严重时将穿透滤层,因此应进行活性炭的再生或更换。

operating principle
The activated carbon adsorption device is mainly composed of active carbon layer and supporting layer. Activated carbon has developed voids, which are larger than the surface area and have a high adsorption capacity. It is precisely because of this characteristic that activated carbon is widely used in the depth treatment of water, such as domestic water supply, and the depth treatment(clean water) of the wastewater.

Dust gas is powered by a fan and enters the tower with positive or negative pressure. Because there is an unbalanced and unsaturated molecular gravity or chemical strength on the solid surface of activated carbon, when the solid surface is in contact with the gas, it can attract gas. molecule, It is concentrated and maintained on the solid surface, and the contaminated material is thus adsorbed. After passing through the filter, the exhaust gas enters the equipment exhaust system to purify the gas discharge at high altitude.
1. High adsorption efficiency, large adsorption capacity, wide application
2. Easy to maintain, no technical requirements
3. Larger than surface area, good selective adsorption
4. Activated carbon has the characteristics of wide source, low price, etc..
5. High adsorption efficiency and capability
6。 Easy to operate, safe

After active carbon is used for a period of time, a large amount of adsorbent has been adsorbed, gradually becoming saturated, losing its ability to work, and will penetrate the filter layer in serious cases. Therefore, activated carbon should be recycled or replaced.
