酸碱废气处理流程简介：
??酸碱废气处理塔分单塔体和双塔体。采用圆形塔体，用法兰分段连接而成。具体由贮液箱、塔体、进风段、喷淋层、填料层、旋流除雾层、出风锥帽、观检孔等组成。
酸碱废气处理的工作原理：
???? 我司的酸碱废气处理（喷淋塔）主要的运作方式是不断酸雾废气由风管引入净化塔，经过填料层，废气与氢氧化钠吸收液进行气液两相充分接触吸收中和反应，酸雾废气经过净化后，再经除雾板脱水除雾后由风机排入大气。吸收液在塔底经水泵增压后在塔顶喷淋而下，较后回流至塔底循环使用。净化后的酸雾废气达到广东省地方排放标准的排放要求，低于国家排放标准。
以下是废气处理工程的工艺流程：排除的酸雾废气→进入风管→经过酸碱废气处理塔→风机→风管→达标排放。
备注：工业废气处理的方法有活性炭吸附法、催化燃烧法、催化氧化法、酸碱中和法、等离子法等。
废气处理设备
废气处理设备，主要是指运用不同工艺技术，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，让我们的环境不受到污染。

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**的吸收剂逆流接触，净化后的气体由塔**排出。吸收了VOCs的吸收剂通过热交换器后，进入汽提塔**部，在温度**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。
废气处理设备吸附设备
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，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。
废气处理设备**废气的燃烧及催化净化设备
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。但当处理含氯和含硫的**化合物时，燃烧生成产物中HCl或SO2，需要对燃烧后气体进一步处理。
Absorptive equipment
VOCs was absorbed by low volatile or non volatile solvents and then separated by VOCs and physical properties of absorbents.
The VOCs gas self absorption tower enters the tower at the bottom and contacts with the absorber from the top of the tower during the rising process. The purified gas is discharged from the top of the tower. The absorbent VOCs absorbs through the heat exchanger and enters the top of the stripper and desorbs when the temperature is higher than the absorption temperature or the pressure is lower than the absorption pressure. After desorption, the absorber is condensed through the solvent condenser and then returned to the absorber. The extracted VOCs gas is recovered from the stripper by using pure VOCs gas after passing through the condenser and gas-liquid separator. The process is suitable for gas purification with high VOCs concentration and low temperature, and other conditions need to be adjusted accordingly.
Adsorption equipment for waste gas treatment equipment
When porous solids are used to treat fluid mixtures, a certain component or component in the fluid can be adsorbed on the surface and concentrated on it. This phenomenon is called adsorption. When adsorbing waste gas, the adsorbed objects are gaseous pollutants and gas-solid adsorption. The adsorbed gas components are called adsorbents, and porous solids are called adsorbents.
After adsorption on the solid surface, an adsorbed adsorbate can be detached from the adsorbent surface. After a period of adsorption, due to the concentration of surface adsorbate, the adsorption capacity of the adsorbate is obviously decreased and the adsorption purification is required. At this time, some measures should be adopted to remove the adsorbed adsorbate on the adsorbent, which is called the adsorption capacity. This process is called the regeneration of adsorbents. Therefore, in the actual adsorption engineering, it is the recycling process of adsorption and regeneration to remove the pollutants in the waste gas and recover the useful components in the waste gas.
Waste gas treatment equipment organic waste gas combustion and catalytic purification equipment
The combustion method is used to deal with high concentration Voc and stinky compounds. The principle is to use excessive air to make these impurities burning, and most of them produce carbon dioxide and water vapor, which can be discharged into the atmosphere. However, when treating organic compounds containing chlorine and sulphur, HCl or SO2 in the combustion products will be further processed.
