在工業(yè)廢氣處理領(lǐng)域，催化燃燒設(shè)備憑借高效、節(jié)能的特性成為核心凈化裝備。其工作流程依托熱交換與催化反應(yīng)雙重機制：待處理廢氣經(jīng)管道由風(fēng)機引入設(shè)備，首先進入熱交換器，通過回收系統(tǒng)余熱將廢氣溫度提升至催化燃燒所需的起始溫度。預(yù)熱后的廢氣隨即進入催化反應(yīng)區(qū)域，在催化劑的作用下發(fā)生氧化分解反應(yīng)，實現(xiàn)有害物質(zhì)的高效轉(zhuǎn)化。

In the field of industrial waste gas treatment, catalytic combustion equipment has become the core purification equipment due to its high efficiency and energy-saving characteristics. Its workflow relies on a dual mechanism of heat exchange and catalytic reaction: the exhaust gas to be treated is introduced into the equipment through a pipeline by a fan, first entering the heat exchanger, and the exhaust gas temperature is raised to the starting temperature required for catalytic combustion by recovering the waste heat from the system. The preheated exhaust gas immediately enters the catalytic reaction zone and undergoes oxidative decomposition reaction under the action of the catalyst, achieving efficient conversion of harmful substances.

由于催化劑的作用，催化燃燒法廢氣燃燒的起始溫度約為250～300攝氏度，低于直接燃燒法的燃燒溫度650～800攝氏度，高溫氣體再次進入熱交換器，經(jīng)換熱冷卻， 終以較低的溫度經(jīng)風(fēng)機排入大氣。

Due to the action of the catalyst, the initial temperature of exhaust gas combustion in catalytic combustion method is about 250-300 degrees Celsius, which is lower than the combustion temperature of 650-800 degrees Celsius in direct combustion method. The high-temperature gas enters the heat exchanger again, is cooled by heat exchange, and finally discharged into the atmosphere at a lower temperature through the fan.

催化燃燒設(shè)備負載方式：催化劑活性組分可通過下列方式沉積在載體上：電沉積在纏繞或壓制的金屬載體上;沉積在顆粒狀陶瓷材料上;沉積在蜂窩結(jié)構(gòu)的陶瓷材料上。

Loading method of catalytic combustion equipment: The active components of the catalyst can be deposited on the carrier through the following methods: electro deposition on a wrapped or pressed metal carrier; Deposited on granular ceramic materials; Deposited on ceramic materials with honeycomb structure.

催化燃燒設(shè)備催化劑在使用過程中隨著時間的延長，活性會逐漸下降，直至失活。催化劑失活主要有3種類型：催化劑完全失活。使催化劑失活的毒物包括和慢速作用毒物兩大類。

The catalytic combustion equipment catalyst will gradually decrease in activity over time during use, until it becomes deactivated. There are three main types of catalyst deactivation: complete deactivation of the catalyst. The toxins that cause catalyst deactivation include two categories: slow acting toxins and slow acting toxins.

作用毒物主要有P、As等，慢速作用毒物有Pb、Zn等。通常情況下，催化劑失活是由于毒物與活性組分化合或熔成合金。催化燃燒設(shè)備控制系統(tǒng)將檢測到的信號與設(shè)定的信號經(jīng)過比較運算后，通過電信號控制變頻器的輸出頻率來調(diào)整風(fēng)機的轉(zhuǎn)速，保持燃燒器的燃燒溫度;催化燃燒設(shè)備自動檢測燃燒器溫度信號與設(shè)定的溫度比較，輸出各類報警信號或直接停機。顯示器可以顯示燃氣流量、燃燒溫度和變頻器輸出頻率。

The main toxic substances are P and As, while slow acting toxins include Pb and Zn. Usually, catalyst deactivation is due to the fusion or melting of toxins and active components into alloys. The control system of catalytic combustion equipment compares the detected signal with the set signal and adjusts the fan speed by controlling the output frequency of the frequency converter through electrical signals to maintain the combustion temperature of the burner; Catalytic combustion equipment automatically detects the temperature signal of the burner and compares it with the set temperature, outputting various alarm signals or directly stopping the machine. The monitor can display gas flow rate, combustion temperature, and output frequency of the frequency converter.
