VOCs（挥发性有机化合物）废气处理工艺标准通常涉及预处理、核心净化以及后处理等环节，以确保达到环保排放标准。以下是一些常见的VOCs废气处理工艺标准：

　　The VOCs (volatile organic compounds) exhaust gas treatment process standards usually involve pre-treatment, core purification, and post-treatment to ensure compliance with environmental emission standards. Here are some common VOCs waste gas treatment process standards:

　　预处理系统

　　Preprocessing system

　　冷凝系统 ：针对高浓度VOCs废气，通过冷凝将废气中的部分组分转化为液体，从而减少气体的体积。

　　Condensation system: For high concentration VOCs exhaust gas, some components in the exhaust gas are converted into liquids through condensation, thereby reducing the volume of the gas.

　　净化塔 ：利用填料或塔板，使废气与洗涤液充分接触，吸收或中和废气中的污染物。

　　Purification tower: Using packing or trays to ensure full contact between exhaust gas and washing solution, absorbing or neutralizing pollutants in the exhaust gas.

　　电离捕捉器 ：用于去除油烟和粉尘等颗粒物。

　　Ionization trap: used to remove particulate matter such as oil fumes and dust.

　　干式过滤器 ：通过物理过滤去除颗粒物和某些气体污染物。

　　Dry filter: removes particulate matter and certain gas pollutants through physical filtration.

　　核心净化系统

　　Core purification system

　　吸附法 ：

　　Adsorption method:

　　小风量低浓度：使用活性炭或沸石作为吸附剂。

　　Low wind volume and low concentration: Use activated carbon or zeolite as adsorbents.

　　中风量低浓度：可采用活性炭吸附脱附、沸石吸附脱附或转轮吸附。

　　Low concentration of stroke volume: Activated carbon adsorption desorption, zeolite adsorption desorption, or rotary adsorption can be used.

　　大风量低浓度：同样可采用活性炭吸附脱附、沸石吸附脱附或转轮吸附。

　　High air volume and low concentration: Activated carbon adsorption desorption, zeolite adsorption desorption, or rotary adsorption can also be used.

　　催化氧化法 ：

　　Catalytic oxidation method:

　　废气通过催化剂床层时，VOCs与氧气发生氧化反应，转化为CO2和H2O。

　　When the exhaust gas passes through the catalyst bed, VOCs undergo oxidation reaction with oxygen, converting into CO2 and H2O.

　　多层光催化剂和紫外灯管配置需符合特定功率要求。

　　The configuration of multi-layer photocatalysts and ultraviolet lamps must meet specific power requirements.

　　生物处理 ：

　　Biological treatment:

　　利用微生物降解VOCs为无害物质，如CO2和H2O。

　　Using microorganisms to degrade VOCs into harmless substances such as CO2 and H2O.

　　对环境条件如温度、湿度有一定要求。

　　There are certain requirements for environmental conditions such as temperature and humidity.

　　后处理系统

　　Post processing system

　　除湿处理 ：进入活性炭吸附设施前应进行除湿处理，记录除湿剂更换周期等信息。

　　Dehumidification treatment: Before entering the activated carbon adsorption facility, dehumidification treatment should be carried out, and information such as the replacement cycle of the desiccant should be recorded.

　　颗粒物去除 ：喷漆工艺废气进入活性炭处理设施前应去除颗粒物。

　　Particulate matter removal: Before entering the activated carbon treatment facility, particulate matter should be removed from the spray painting process exhaust gas.

　　设计参数

　　Design parameters

　　吸附剂装填量与设计风量的关系：每万立方米/小时设计风量的吸附剂装填量应不小于1立方米。

　　The relationship between adsorbent loading amount and design air volume: The adsorbent loading amount per 10000 cubic meters per hour of design air volume should not be less than 1 cubic meter.

　　废气停留时间：废气停留时间不得低于1秒，对于某些工艺可能要求更高。

　　Exhaust gas residence time: The exhaust gas residence time shall not be less than 1 second, and may be higher for certain processes.

　　排放要求

　　Emission requirements

　　废气收集系统排风罩设置应符合GB/T16758的规定，吸入风速应不低于0.6米/秒。

　　The exhaust hood of the exhaust gas collection system should comply with the provisions of GB/T16758, and the suction wind speed should not be less than 0.6 meters per second.

　　以上信息结合了不同来源的规范和要求，具体实施时应参照最新的环保法规和行业标准。

　　The above information combines specifications and requirements from different sources, and specific implementation should refer to the latest environmental regulations and industry standards.
