1、预处理
1. Pretreatment
对于有机废气,人们应首先开展水喷淋,去除废气内部的杂尘、可溶性有机物。喷淋后,气体内部具有大量水分和少量粉尘,为避免水分与粉尘影响活性炭吸附床的有效运行,人们需要在处理时利用高效率的过滤器进行过滤。
For organic waste gas, people should first carry out water spraying to remove the dust and soluble organic matter in the waste gas. After spraying, there is a large amount of moisture and a small amount of dust in the gas. In order to avoid the influence of moisture and dust on the effective operation of activated carbon adsorption bed, people need to use high-efficiency filters for filtration.
2、吸附操作
2. Adsorption operation
经过预处理的有机废气,在风机的作用下引入吸附床,将其均匀地分布在活性炭表面。依据分子间的范德华力,活性炭会将有机废气吸附在表面,这一过程耗时较少,但时间越长,吸附越彻底。二者之间不会发生较大的化学反应,而有机废气却达到较高的净化效果。经过净化后的洁净废气可以达到环保部门规定的污染物排放标准。此外在风机的作用下,可以达到离地15m高空排放的标准。每套废气净化处理系统含多个级别的吸附床,两套用来吸附,一套用来脱附,设备之间可以实现轮流操作。
The pretreated organic waste gas is introduced into the adsorption bed under the action of the fan and evenly distributed on the surface of the activated carbon. According to the intermolecular van der Waals force, the activated carbon will adsorb the organic waste gas on the surface, which takes less time, but the longer the time, the more thorough the adsorption. There is no big chemical reaction between the two, but the organic waste gas has a high purification effect. The purified waste gas can meet the pollutant emission standard of environmental protection department. In addition, under the action of the fan, it can reach the emission standard of 15m above the ground. Each set of waste gas purification and treatment system contains several levels of adsorption beds, two for adsorption and one for desorption. The operation between the equipment can be carried out in turn.

3、脱附与催化燃烧
3. Desorption and catalytic combustion
在活性炭吸附到饱和程度后,切换到脱附床。脱附需要外加热量,加热装置安装在催化氧化床的内部,开启后同时预热催化剂。催化氧化床达到设定的温度后,将热空气引入脱附床内部,有机废气在加热的作用下从活性炭表面全部解析出来。
After the activated carbon was saturated, it was switched to desorption bed. The heating device is installed inside the catalytic oxidation bed, and the catalyst is preheated after opening. After the catalytic oxidation bed reaches the set temperature, the hot air is introduced into the desorption bed, and the organic waste gas is completely separated from the surface of the activated carbon by heating.
高浓度的有机废气在外力的作用下进入氧化床中,通过金属铂的催化作用,被燃烧分解为水和二氧化碳,废气通过这一操作得到净化。这一燃烧过程的特征为低温、快速以及无焰,并产生较大的热量。我们可以将活性炭再次回用到有机废气的脱附与燃烧氧化中,从而降低能源消耗。
Under the action of external force, the high concentration organic waste gas enters the oxidation bed and is decomposed into water and carbon dioxide by the catalytic action of platinum. The waste gas is purified by this operation. The combustion process is characterized by low temperature, high speed, flameless and large heat generation. We can reuse the activated carbon in the desorption and combustion oxidation of organic waste gas to reduce energy consumption.
催化燃烧过程在有机废气浓度较大时,燃烧产生的热量过多会导致催化氧化床的温度较大,进而影响整个废气处理系统的安全性。为此,韵蓝环保设计的系统含有冷空气补充装置,它可以引入新鲜空气来降低反应温度,从而保证系统操作的安全性。
In the process of catalytic combustion, when the concentration of organic waste gas is high, the excessive heat generated by combustion will lead to the high temperature of catalytic oxidation bed, which will affect the safety of the whole waste gas treatment system. Therefore, the system of Yunlan environmental protection design contains cold air supplement device, which can introduce fresh air to reduce the reaction temperature, so as to ensure the safety of system operation.
