活性炭催化燃烧设备特点介绍
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.
废气通过上面的阀门进入到脱附通道,然后进入到催化燃烧室跟催化剂进行反应,反应过程中产生高温气体,温度一般在260-380摄氏度,当温度达到300摄氏度时,组加热管关闭,温度到350度时,第二组加热管关闭,温度达到380度时,三组加热管全部关闭。电加热全部关闭之后节约电源,催化剂周围放有陶瓷蓄热体,可以有效的锁住热量,催化剂可以长时间的进行无加热的反应,当温度低于300摄氏度时,电加热自启动,又开始加热。不需人员控制。节省人力和能源。
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—催化燃烧脱附是把以上两者的优点有效地结合起来。先利用活性碳进行吸附,当吸附饱和时,启动催化燃烧设备,并利用热空气局部加热活性碳吸附床,当催化燃烧反应床加热到250℃,活性碳吸附床局部达到60~110℃时,脱附出来的高浓度废气可在催化反应床中进行氧化分解。反应后的高温气体经换热器的换热,换热后的气体一部分再次送入活性碳吸附床进行脱附,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.
根据废气浓度的含量不同,脱附时间也不同。活性炭的脱附过程都是在线脱附,就是当活性炭饱和后设备会自动进行脱附,不需要有人去经常查看,节省了人工费用。活性炭进行脱附时会根据箱体的多少进行三吸一脱或者是四吸一脱等,就是脱附的时候并不是全部脱附,只有一个箱体在脱附,其余的箱体仍然在工作。这样是不会耽误工厂使用的。
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.
催化燃烧设备根据废气含量的不同和每天工作时间的不同,设定脱附时间。一般15-20天进行脱附。脱附时间为3-5小时。催化燃烧设备的脱附时间主要由活性炭的填充量和活性炭的吸附值来决定。活性炭的填充量高,吸附值高,催化燃烧设备的脱附时间间隔就比较长,间隔时间长的一般为15-20天进行脱附,如果催化燃烧设备选用的活性炭吸附值低,而且设备里活性炭的填充量又少,催化燃烧设备就很容易达到饱和。像这种催化燃烧设备一般的脱附时间为3-5天就必须脱附一次,这样就很大的浪费电量。增加使用费用,而且活性炭的使用寿命短,好的活性炭一般2-3年更换一次,像这种需要经常需要脱附的催化燃烧设备的活性炭基本一年就需要更换一次。
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.
