废气处理设备的不同工艺技术 Different technology of waste gas treatment equipment

    废气处理设备厂家供应的废气处理设备，主要是运用不同工艺技术，通过回收或去除减少排放尾气的有害成分，达到保护环境、净化空气的一种环保设备。

    废气处理设备，主要是运用不同工艺技术，通过吸附、分解、降解等办法，去除减少排放尾气的有害成分，达到国家环保部门要求的排放标准的一种环保设备。
       废气处理设备主要分为以下几种：
吸收设备
       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。
       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。吸收了VOCs的吸收剂通过热交换器后，进入汽提塔顶部，在温度高于吸收温度或压力低于吸收压力的条件下解吸。解吸后的吸收剂经过溶剂冷凝器冷凝后回到吸收塔。解吸出的VOCs气体经过冷凝器、气液分离器后以较纯的VOCs气体离开汽提塔，被回收利用。该工艺适合于VOCs浓度较高、温度较低的气体净化，其他情况下需要作相应的工艺调整。

吸附设备
       在用多孔性固体物质处理流体混合物时，流体中的某一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，吸附的对象是气态污染物，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。
       固体表面吸附了吸附质后，废气处理设备厂家解说一部被吸附的吸附质可从吸附剂表面脱离，此现附。而当吸附进行一段时间后，由于表面吸附质的浓集，使其吸附能力明显下降而吸附净化的要求，此时需要采用一定的措施使吸附剂上已吸附的吸附质脱附，以协的吸附能力，这个过程称为吸附剂的再生。因此在实际吸附工程中，正是利用吸附一再生一再吸附的循环过程，达到除去废气中污染物质并回收废气中有用组分。

The waste gas treatment equipment supplied by the manufacturer of the waste gas treatment equipment is mainly a kind of environmental protection equipment that can protect the environment and purify the air through recycling or removing the harmful components of the exhaust gas to reduce the emission.

The waste gas treatment equipment is mainly a kind of environmental protection equipment which USES different technologies to remove the harmful components of the exhaust gas by means of adsorption, decomposition and degradation and meets the emission standards required by the national environmental protection department.
Waste gas treatment equipment is mainly divided into the following:
The absorption equipment
The absorption method USES low volatile or non-volatile solvent to absorb VOCs, and reuses the difference of physical properties of VOCs and absorbent to separate.
The gas containing VOCs enters the bottom of the absorption tower, and in the rising process, it contacts with the absorbent from the top of the tower upstream. The purified gas is discharged from the top of the tower. After absorbing VOCs absorbent through the heat exchanger, it enters the top of the stripper and desorption under the condition that the temperature is higher than the absorption temperature or the pressure is lower than the absorption pressure. The desorption absorbent is condensed by solvent condenser and returned to the absorber. The desorption VOCs gas leaves the stripper with relatively pure VOCs gas after passing through the condenser and gas-liquid separator and is recycled. This process is suitable for the gas purification with higher VOCs concentration and lower temperature. In other cases, corresponding process adjustment should be made.

Adsorption equipment
When a fluid mixture is treated with a porous solid, a component or component of the fluid may be sucked onto the surface and concentrated on it. This phenomenon is called adsorption. When the waste gas is adsorbed, the object of adsorption is gaseous pollutant and gas-solid adsorption. The adsorbed gas component is called adsorbent, porous solid material is called adsorbent.
After adsorption of the adsorbent on the solid surface, the waste gas treatment equipment manufacturer explained that the adsorbed adsorbent can be separated from the adsorbent surface. When the adsorption is carried out for a period of time, due to the concentration of the surface adsorbent, its adsorption capacity is obviously reduced and the requirement of adsorption purification is required. At this time, certain measures should be adopted to desorption the adsorbed adsorbents on the adsorbent, so as to achieve the co-adsorption capacity. This process is called adsorbent regeneration. Therefore, in the actual adsorption engineering, it is the recycling process of adsorption, regeneration and adsorption that can be used to remove the pollutants from the waste gas and recover the useful components from the waste gas.
