医药化工行业可以划分为中药类制药工业、发酵类制药工业、混装制剂类制药工业、化学合成类制药工业、提取类制药工业和生物工程类制药工业。

The pharmaceutical and chemical industry can be divided into traditional Chinese medicine pharmaceutical industry, fermentation pharmaceutical industry, mixed formulation pharmaceutical industry, chemical synthesis pharmaceutical industry, extraction pharmaceutical industry, and biotechnology pharmaceutical industry.

其中发酵类制药工业和化学合成类制药工业是涉VOCs废气排放的大户，原辅料的生产过程中部分有机溶剂挥发以及粉碎筛分工段都会产生废气排放，此外，生产车间和公用工程在生产过程中也会产生一部分的无组织废气。医药化工行业产生的废气排放量大、排放风量不稳定，污染物的浓度和种类变化较大，恶臭成分会对周边环境造成严重污染。

The fermentation pharmaceutical industry and chemical synthesis pharmaceutical industry are major emitters of VOCs waste gas. During the production process of raw materials, some organic solvents evaporate and the crushing and screening sections produce waste gas emissions. In addition, production workshops and public works also generate some unorganized waste gas during the production process. The pharmaceutical and chemical industry generates a large amount of exhaust gas emissions, unstable air flow, and significant changes in the concentration and types of pollutants. Odor components can cause serious pollution to the surrounding environment.

随着环保政策出台以及环保标准的逐步提升，大气环境改善迫在眉睫，废气治理势在必行。医药化工VOCs的治理方法包括蓄热燃烧法、催化燃烧法、沸石转轮吸附浓缩-RTO协同技术等。

With the introduction of environmental policies and the gradual improvement of environmental standards, the improvement of atmospheric environment is urgent, and the treatment of exhaust gas is imperative. The treatment methods for VOCs in the pharmaceutical and chemical industry include thermal storage combustion, catalytic combustion, zeolite rotary adsorption concentration RTO synergistic technology, etc.

一、活性炭催化燃烧

1、 Activated carbon catalytic combustion

挥发性有机废气（VOCs）经高效过滤器过滤后，进入蜂窝活性炭吸附模块被吸附、浓缩，借助催化剂使有机废气在较低的起燃温度条件下，发生无焰燃烧，并氧化分解为二氧化碳和水，从而达到净化废气的目的。

After being filtered by a high-efficiency filter, volatile organic compounds (VOCs) enter the honeycomb activated carbon adsorption module for adsorption and concentration. With the help of a catalyst, the organic waste gas undergoes flameless combustion at a lower ignition temperature and is oxidized and decomposed into carbon dioxide and water, thereby achieving the goal of purifying the waste gas.

该设备更适合大风量、低浓度有机废气处理，VOCs净化效率可高达95%以上，几乎可以处理所有的烃类有机废气及恶臭气体，并且具有能耗低、后期运行成本低、安全方便且无二次污染的优点。

This device is more suitable for the treatment of high air volume and low concentration organic waste gas, with a VOCs purification efficiency of over 95%. It can almost treat all hydrocarbon organic waste gas and odorous gases, and has the advantages of low energy consumption, low operating costs in the later stage, safety and convenience, and no secondary pollution.

二、沸石转轮催化燃烧

2、 Zeolite rotary catalytic combustion

沸石转轮吸附浓缩装置以陶瓷纤维为基材，表面涂覆疏水性沸石做吸附剂，通过沸石转轮对挥发性有机废气进行吸附压缩，提高浓度，再将高浓度的废气分子脱附后送入催化氧化炉进行无焰燃烧，分解成二氧化碳和水，达到对有机废气净化的目的。

The zeolite rotary adsorption concentration device uses ceramic fibers as the substrate and is coated with hydrophobic zeolite as the adsorbent on the surface. The zeolite rotary is used to adsorb and compress volatile organic waste gas, increasing its concentration. The high concentration waste gas molecules are then desorbed and sent to a catalytic oxidation furnace for flameless combustion, decomposing into carbon dioxide and water, achieving the purpose of purifying organic waste gas.

该吸附装置采用吸附－脱附－浓缩焚化三项连续程序，特别适合于大风量、低浓度有机废气的治理，对有机废气的吸附能力更强、过滤效果更好，对当前环保重点要求的笨、甲苯、二甲苯、非甲烷总烃等有机废气处理有显著效果。

This adsorption device adopts a continuous process of adsorption desorption concentration incineration, which is particularly suitable for the treatment of high air volume and low concentration organic waste gas. It has stronger adsorption capacity and better filtration effect for organic waste gas, and has significant effects on the treatment of organic waste gas such as benzene, toluene, xylene, and non methane hydrocarbons that are currently key environmental protection requirements.

三、蓄热式燃烧分解

3、 Regenerative combustion decomposition

蓄热式燃烧分解技术是在直接燃烧法的基础上发展出来的新技术，通过燃烧天然气在高温下将有机废气氧化分解为二氧化碳和水，实现净化处理。RTO设备内装有陶瓷蓄热体，能够将燃烧废气时产生的热量充分利用起来，且系统维护工作少，与直接燃烧法相比，大大降低了运行费用。由于节能效果明显 ，RTO设备在有机废气治理中得到了广泛应用。

Thermal storage combustion decomposition technology is a new technology developed on the basis of direct combustion method, which oxidizes and decomposes organic waste gas into carbon dioxide and water at high temperature by burning natural gas, achieving purification treatment. The RTO equipment is equipped with ceramic heat storage bodies, which can fully utilize the heat generated during the combustion of exhaust gas, and require less system maintenance work. Compared with direct combustion methods, it greatly reduces operating costs. Due to its significant energy-saving effect, RTO equipment has been widely used in organic waste gas treatment.

RTO设备对挥发性有机物的去除效率较高，两室RTO装置VOCs的去除率在95%—98%，三室RTO装置VOCs去除率可达98%以上，是目前我国有机废气治理的主要技术之一 。

RTO equipment has a high removal efficiency for volatile organic compounds, with a removal rate of 95% -98% for VOCs in two chamber RTO devices and over 98% in three chamber RTO devices. It is currently one of the main technologies for organic waste gas treatment in China.
