Supply VOC activated carbon adsorption tower of Shandong waste gas treatment equipment manufacture

  Activated carbon adsorption tower uses the surface force of high-performance activated carbon adsorbent solid itself to attract and attach the adsorbate of VOC molecules to the surface of adsorbent, so as to achieve the purpose of removing VOC substances Activated carbon adsorption method can ideally remove volatile organic compounds from waste gas under the condition of low concentration VOC, and has better economic benefits
Therefore, in terms of air pollutant control, it is especially suitable for the treatment of waste gas containing low concentration VOC, such as semiconductor factory, LCD factory, PCB Factory and related electronic factory According to the different attraction between adsorbent and adsorbent, the mechanism of adsorption method includes physical adsorption by van der Waals force between substances and chemical action by using chemical bond
The physical action is a reversible phenomenon, which is often used to destroy the balance by changing the pressure or temperature to regenerate the adsorbent and recover the adsorbed materials, such as steam regeneration, chemical oxidation regeneration, microwave regeneration, etc; The chemical reaction is highly exothermic and usually irreversible There are many kinds of adsorbents, but activated carbon is often used, mainly because activated carbon has good physical adsorption effect on some VOCs, easy recovery and regeneration, and low price; As for other adsorbents, such as silica gel, diatomite, activated alumina or synthetic zeolite, the adsorption selectivity of VOC is high
Therefore, it is necessary to select suitable adsorbents in combination with the characteristics of waste gas pollutants
