2、活性炭的吸附原理

吸附现象是发生在两个不同的相界面的现象BG视讯官方网站BG视讯官方网站BG视讯官方网站,吸附过程就是在界面上的扩散过程,是发生在固体表面的吸附,这是由于固体表面存在着剩余的吸引而引起的BG视讯官方网站BG视讯官方网站。


吸附可分为物理吸附和化学吸附;物理吸附亦称范德华吸附BG视讯官方网站,是由于吸附剂与吸附质分子之间的静电力或范德华引力导致物理吸附引起的BG视讯官方网站BG视讯官方网站BG视讯官方网站,当固体和气体之间的分子引力大于气体分子之间的引力时BG视讯官方网站,即使气体的压力低于与操作温度相对应和饱和蒸气压,气体分子也会冷凝在固体表面上,物理吸附是一种吸热过程BG视讯官方网站。


化学吸附亦称活性吸附BG视讯官方网站,是由于吸附剂表面与吸附质分子间的化学反应力导致化学吸附BG视讯官方网站BG视讯官方网站,它涉及分子中化学键的破坏和重新结合BG视讯官方网站,因此BG视讯官方网站,化学吸附过程的吸附热较物理吸附过程大BG视讯官方网站。


在吸附过程中BG视讯官方网站BG视讯官方网站,物理吸附和化学吸附之间没有严格的界限BG视讯官方网站,同一物质在较低温度下往往是化学吸附BG视讯官方网站BG视讯官方网站G视讯官方网站BG视讯官方网站BG视讯官方网站BG视讯官方网站;钚蕴肯宋揭晕锢砦轿?BG视讯官方网站BG视讯官方网站,但由于表面活性剂的存在,也有一定的化学吸附作用BG视讯官方网站BG视讯官方网站。



3、工艺说明


车间有机废气通过吸气罩收集BG视讯官方网站BG视讯官方网站BG视讯官方网站,在排风机作用下,经过管道输送进入干式过滤器,再进入活性炭吸附装置BG视讯官方网站,有机污染物被活性炭吸附BG视讯官方网站,净化后的气体经风机增压后达标排放BG视讯官方网站BG视讯官方网站。


活性炭吸附饱和后BG视讯官方网站BG视讯官方网站BG视讯官方网站BG视讯官方网站,请专业厂家再生后回用BG视讯官方网站。

2, activated carbon adsorption principle

Adsorption phenomenon is the phenomenon occurs in two distinct phase interface, the adsorption process is the diffusion process at the interface, adsorption occurs at a solid surface, which is due to the existence of the remaining solid surface attraction caused.


Can be divided into physical adsorption and chemical adsorption; physical adsorption, also known as the van der Waals adsorption is due to the electrostatic force between the adsorbent and adsorbate molecules or van der Waals attraction leads to physical adsorption caused when the molecular attraction between the solid and gas is greater than the gas when the attractive force between molecules, even if the operating pressure of the gas is lower than the temperature corresponding to the saturated vapor pressure, will condense the gas molecules on a solid surface, physical adsorption is an endothermic process.


Also known as chemisorption active adsorption, chemical reaction force due to the surface of the adsorbent and adsorbate molecules cause chemical adsorption, which involves the destruction of chemical bonds in molecules and recombine, therefore, the heat of adsorption chemisorption process relatively large physical adsorption process.


In the adsorption process, there is no strict boundaries between physical and chemical adsorption, chemisorption is often the same substance at lower temperatures. Activated Carbon Fiber physical adsorption based, but due to the presence of a surfactant, there are certain chemical adsorption.


3, process description

Drag organic waste collected by the hood, under the effect of the exhaust fan through the pipeline entering the dry filter, and then into the activated carbon adsorption unit, activated carbon adsorption of organic pollutants, the purified gas booster fan after discharge.


After the activated carbon adsorption saturation, please post professional manufacturers Reuse.
