性炭催化燃燒設(shè)備進(jìn)行脫附時(shí)，首先空氣通過脫附風(fēng)機(jī)進(jìn)入到催化燃燒室，通過催化燃燒室內(nèi)的加熱器進(jìn)行升溫，但溫度達(dá)到200攝氏度時(shí)，通過熱交換器進(jìn)入脫附管道，在脫附管道內(nèi)的混流箱內(nèi)進(jìn)行降溫，當(dāng)混流箱內(nèi)的溫度達(dá)到活性炭的脫附溫度時(shí)通過閥門進(jìn)入活性炭吸附箱體，對(duì)活性炭進(jìn)行脫附。
When the catalytic combustion equipment is desorbed, firstly, the air enters the catalytic combustion chamber through the desorbing fan, and the temperature is raised by the heater in the catalytic combustion chamber. However, when the temperature reaches 200 ℃, the air enters the desorbing pipeline through the heat exchanger, and the temperature is lowered in the mixed flow box in the desorbing pipeline, When the temperature in the mixed flow box reaches the desorption temperature of the activated carbon, it enters the activated carbon adsorption box through the valve to desorb the activated carbon.
廢氣通過上面的閥門進(jìn)入到脫附通道，然后進(jìn)入到催化燃燒室跟催化劑進(jìn)行反應(yīng)，反應(yīng)過程中產(chǎn)生高溫氣體，溫度一般在260-380攝氏度，當(dāng)溫度達(dá)到300攝氏度時(shí)，第一組加熱管關(guān)閉，溫度到350度時(shí)，第二組加熱管關(guān)閉，溫度達(dá)到380度時(shí)，三組加熱管全部關(guān)閉。電加熱全部關(guān)閉之后節(jié)約電源，催化劑周圍放有陶瓷蓄熱體，可以有效的鎖住熱量，催化劑可以長(zhǎng)時(shí)間的進(jìn)行無(wú)加熱的反應(yīng)，當(dāng)溫度低于300攝氏度時(shí)，電加熱自啟動(dòng)，又開始加熱。不需人員控制。節(jié)省人力和能源。
The exhaust gas enters the desorption channel through the above valve, and then enters the catalytic combustion chamber to react with the catalyst. High temperature gas is produced in the reaction process, and the temperature is generally 260-380 ℃. When the temperature reaches 300 ℃, the first group of heating tubes are closed. When the temperature reaches 350 ℃, the second group of heating tubes are closed. When the temperature reaches 380 ℃, all three groups of heating tubes are closed. After all the electric heating is turned off, the power is saved. There is a ceramic heat storage body around the catalyst, which can effectively lock the heat. The catalyst can carry out the reaction without heating for a long time. When the temperature is lower than 300 ℃, the electric heating starts up and starts heating again. There is no need for personnel control. Save manpower and energy.
活性碳吸附—催化燃燒脫附是把以上兩者的優(yōu)點(diǎn)有效地結(jié)合起來(lái)。先利用活性碳進(jìn)行吸附，當(dāng)吸附飽和時(shí)，啟動(dòng)催化燃燒設(shè)備，并利用熱空氣局部加熱活性碳吸附床，當(dāng)催化燃燒反應(yīng)床加熱到250℃，活性碳吸附床局部達(dá)到60～110℃時(shí)，脫附出來(lái)的高濃度廢氣可在催化反應(yīng)床中進(jìn)行氧化分解。反應(yīng)后的高溫氣體經(jīng)換熱器的換熱，換熱后的氣體一部分再次送入活性碳吸附床進(jìn)行脫附，另一部分直接排放。

Activated carbon adsorption catalytic combustion desorption is an effective combination of the above two advantages. Firstly, the activated carbon is used for adsorption. When the adsorption is saturated, the catalytic combustion equipment is started and the activated carbon adsorption bed is locally heated by hot air. When the catalytic combustion reaction bed is heated to 250 ℃ and the activated carbon adsorption bed is locally heated to 60-110 ℃, the desorbed high concentration waste gas can be oxidized and decomposed in the catalytic reaction bed. After the reaction, the high temperature gas is transferred through the heat exchanger. One part of the gas is sent to the activated carbon adsorption bed for desorption, and the other part is directly discharged.
根據(jù)廢氣濃度的含量不同，脫附時(shí)間也不同?；钚蕴康拿摳竭^程都是在線脫附，就是當(dāng)活性炭飽和后設(shè)備會(huì)自動(dòng)進(jìn)行脫附，不需要有人去經(jīng)常查看，節(jié)省了人工費(fèi)用。活性炭進(jìn)行脫附時(shí)會(huì)根據(jù)箱體的多少進(jìn)行三吸一脫或者是四吸一脫等，就是脫附的時(shí)候并不是全部脫附，只有一個(gè)箱體在脫附，其余的箱體仍然在工作。這樣是不會(huì)耽誤工廠使用的。
The desorption time varies with the concentration of waste gas. The desorption process of activated carbon is on-line desorption, that is, when the activated carbon is saturated, the equipment will automatically desorb, so it does not need someone to check it frequently, which saves the labor cost. When the activated carbon is desorbed, it will carry out three absorption and one desorption or four absorption and one desorption according to the number of boxes. That is to say, not all the boxes are desorbed. Only one box is desorbing, and the rest boxes are still working. This will not delay the use of the factory.
催化燃燒設(shè)備根據(jù)廢氣含量的不同和每天工作時(shí)間的不同，設(shè)定脫附時(shí)間。一般15-20天進(jìn)行脫附。脫附時(shí)間為3-5小時(shí)。催化燃燒設(shè)備的脫附時(shí)間主要由活性炭的填充量和活性炭的吸附值來(lái)決定?；钚蕴康奶畛淞扛?，吸附值高，催化燃燒設(shè)備的脫附時(shí)間間隔就比較長(zhǎng)，間隔時(shí)間長(zhǎng)的一般為15-20天進(jìn)行脫附，如果催化燃燒設(shè)備選用的活性炭吸附值低，而且設(shè)備里活性炭的填充量又少，催化燃燒設(shè)備就很容易達(dá)到飽和。像這種催化燃燒設(shè)備一般的脫附時(shí)間為3-5天就必須脫附一次，這樣就很大的浪費(fèi)電量。增加使用費(fèi)用，而且活性炭的使用壽命短，好的活性炭一般2-3年更換一次，像這種需要經(jīng)常需要脫附的催化燃燒設(shè)備的活性炭基本一年就需要更換一次。
The desorption time of catalytic combustion equipment is set according to the different exhaust gas content and daily working time. Generally 15-20 days for desorption. The desorption time was 3-5 hours. The desorption time of catalytic combustion equipment is mainly determined by the amount of activated carbon and the adsorption value of activated carbon. The desorption time interval of catalytic combustion equipment is relatively long when the filling amount of activated carbon is high and the adsorption value is high, and the desorption time interval is generally 15-20 days. If the adsorption value of activated carbon selected by catalytic combustion equipment is low and the filling amount of activated carbon in the equipment is small, the catalytic combustion equipment is easy to reach saturation. The desorption time of this kind of catalytic combustion equipment is 3-5 days, so it must be desorbed once, which is a great waste of electricity. Increase the cost of use, and the service life of activated carbon is short. Good activated carbon is usually replaced once every 2-3 years. For example, the activated carbon of catalytic combustion equipment which often needs desorption needs to be replaced once a year.
