醫藥化工行業可以劃分為中藥類制藥工業、發酵類制藥工業、混裝制劑類制藥工業、化學合成類制藥工業、提取類制藥工業和生物工程類制藥工業。

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.

其中發酵類制藥工業和化學合成類制藥工業是涉VOCs廢氣排放的大戶，原輔料的生產過程中部分有機溶劑揮發以及粉碎篩分工段都會產生廢氣排放，此外，生產車間和公用工程在生產過程中也會產生一部分的無組織廢氣。醫藥化工行業產生的廢氣排放量大、排放風量不穩定，污染物的濃度和種類變化較大，惡臭成分會對周邊環境造成嚴重污染。

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.

隨著環保政策出臺以及環保標準的逐步提升，大氣環境改善迫在眉睫，廢氣治理勢在必行。醫藥化工VOCs的治理方法包括蓄熱燃燒法、催化燃燒法、沸石轉輪吸附濃縮-RTO協同技術等。

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、活性炭催化燃燒

1、 Activated carbon catalytic combustion

揮發性有機廢氣（VOCs）經高效過濾器過濾后，進入蜂窩活性炭吸附模塊被吸附、濃縮，借助催化劑使有機廢氣在較低的起燃溫度條件下，發生無焰燃燒，并氧化分解為二氧化碳和水，從而達到凈化廢氣的目的。

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.

該設備更適合大風量、低濃度有機廢氣處理，VOCs凈化效率可高達95%以上，幾乎可以處理所有的烴類有機廢氣及惡臭氣體，并且具有能耗低、后期運行成本低、安全方便且無二次污染的優點。

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、沸石轉輪催化燃燒

2、 Zeolite rotary catalytic combustion

沸石轉輪吸附濃縮裝置以陶瓷纖維為基材，表面涂覆疏水性沸石做吸附劑，通過沸石轉輪對揮發性有機廢氣進行吸附壓縮，提高濃度，再將高濃度的廢氣分子脫附后送入催化氧化爐進行無焰燃燒，分解成二氧化碳和水，達到對有機廢氣凈化的目的。

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.

該吸附裝置采用吸附－脫附－濃縮焚化三項連續程序，特別適合于大風量、低濃度有機廢氣的治理，對有機廢氣的吸附能力更強、過濾效果更好，對當前環保重點要求的笨、甲苯、二甲苯、非甲烷總烴等有機廢氣處理有顯著效果。

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、蓄熱式燃燒分解

3、 Regenerative combustion decomposition

蓄熱式燃燒分解技術是在直接燃燒法的基礎上發展出來的新技術，通過燃燒天然氣在高溫下將有機廢氣氧化分解為二氧化碳和水，實現凈化處理。RTO設備內裝有陶瓷蓄熱體，能夠將燃燒廢氣時產生的熱量充分利用起來，且系統維護工作少，與直接燃燒法相比，大大降低了運行費用。由于節能效果明顯 ，RTO設備在有機廢氣治理中得到了廣泛應用。

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設備對揮發性有機物的去除效率較高，兩室RTO裝置VOCs的去除率在95%—98%，三室RTO裝置VOCs去除率可達98%以上，是目前我國有機廢氣治理的主要技術之一 。

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.
