　　VOCs waste gas treatment methods

　　微納米氣泡技術(shù)

　　Micro nano bubble technology

　　工作原理及特性：微納米氣泡具有體積小、較強(qiáng)的氧化性等特點(diǎn)，應(yīng)用具有操作簡便、無二次污染等優(yōu)勢。目前對微納米氣泡的形成規(guī)律具有不同于普通氣泡的特性，其特性有待進(jìn)一步開發(fā)利用。

　　Working principle and characteristics: Micro nano bubbles have the characteristics of small volume and strong oxidizing properties, and their application has the advantages of easy operation and no secondary pollution. At present, the formation law of micro nano bubbles has characteristics different from ordinary bubbles, and their characteristics need further development and utilization.

　　在噴涂廢氣治理中的應(yīng)用：通過試驗(yàn)研究了微納米氣泡技術(shù)在噴涂廢氣治理中的應(yīng)用情況。試驗(yàn)主要分為漆霧捕捉及廢氣凈化兩部分，結(jié)果表明微納米氣泡技術(shù)對漆霧的捕捉效果較佳，對廢氣的凈化效率約為 60%，可用作噴涂廢氣的前處理技術(shù)。

　　Application in Spray Waste Gas Treatment: The application of micro nano bubble technology in spray waste gas treatment was studied through experiments. The experiment is mainly divided into two parts: paint mist capture and exhaust gas purification. The results show that micro nano bubble technology has a better capture effect on paint mist, with a purification efficiency of about 60% for exhaust gas. It can be used as a pre-treatment technology for spraying exhaust gas.

　　分散式無動力廢氣處理設(shè)備

　　Distributed non powered exhaust gas treatment equipment

　　設(shè)備特點(diǎn)：針對石油煉化企業(yè)污水集輸系統(tǒng)無組織排放廢氣的問題，設(shè)計(jì)采用一種典型的分散式無動力廢氣處理設(shè)備。該設(shè)備具有體積小、安裝布置靈活等特點(diǎn)，集脫硫、除臭、膜分離、吸附、催化分解和生物降解等于一體，可以實(shí)現(xiàn)就地即時收集、即時處理、即時排放，同時能保持管網(wǎng)壓力平衡，維持管網(wǎng)原有的功能，實(shí)現(xiàn)集輸管網(wǎng)無組織廢氣排放的分散式治理，排放滿足《石油煉制工業(yè)污染物排放標(biāo)準(zhǔn)》GB31570 - 2015 限值要求。

　　Equipment features: In response to the problem of unorganized emission of waste gas from the sewage collection and transportation system of petroleum refining enterprises, a typical decentralized non powered waste gas treatment equipment is designed and adopted. This equipment has the characteristics of small size and flexible installation and layout. It integrates desulfurization, deodorization, membrane separation, adsorption, catalytic decomposition, and biodegradation, and can achieve on-site real-time collection, treatment, and discharge. At the same time, it can maintain the pressure balance of the pipeline network, maintain the original functions of the pipeline network, and achieve decentralized treatment of unorganized waste gas emissions in the gathering and transportation pipeline network. The emissions meet the limit requirements of the "Petroleum Refining Industry Pollutant Emission Standard" GB31570-2015.

　　燃燒處理方法

　　Combustion treatment method

　　分類及原理：燃燒法在工業(yè) VOCs 廢氣處理中最為成熟、應(yīng)用最廣泛。燃燒法分為直接燃燒法、熱力燃燒法和催化燃燒法三大類。直接燃燒法是將廢氣直接引入燃燒爐中進(jìn)行燃燒；熱力燃燒法是通過添加輔助燃料提高廢氣溫度，使其達(dá)到燃燒溫度進(jìn)行燃燒；催化燃燒法是在催化劑的作用下，降低廢氣的燃燒溫度，使其在較低溫度下進(jìn)行燃燒。

　　Classification and principle: Combustion method is the most mature and widely used in the treatment of industrial VOCs waste gas. Combustion methods are divided into three categories: direct combustion, thermal combustion, and catalytic combustion. The direct combustion method is to directly introduce exhaust gas into the combustion furnace for combustion; Thermal combustion method is to increase the exhaust gas temperature by adding auxiliary fuel to reach the combustion temperature for combustion; Catalytic combustion method is the process of reducing the combustion temperature of exhaust gas under the action of a catalyst, allowing it to burn at a lower temperature.

　　優(yōu)缺點(diǎn)：燃燒法在高溫下徹底破壞和去除了 VOCs，不會產(chǎn)生二次污染。但直接燃燒法需要較高的燃燒溫度，能耗較大；熱力燃燒法需要添加輔助燃料，成本較高；催化燃燒法對催化劑的要求較高，催化劑容易失活。

　　Advantages and disadvantages: The combustion method completely destroys and removes VOCs at high temperatures, without generating secondary pollution. But the direct combustion method requires a higher combustion temperature and consumes more energy; Thermal combustion method requires the addition of auxiliary fuel, which is costly; Catalytic combustion method has high requirements for catalysts, which are prone to deactivation.
