Why VOC Adsorbents Have Gradually Become Environmental Remediation Tools

VOC adsorbent is the adsorption generated by intermolecular forces. This is a very common adsorption phenomenon, characterized by the molecules of the adsorbate not being attached to fixed points on the surface of the adsorbent for adsorption, but rather being able to move freely at the interface. Because adsorption is caused by intermolecular forces, the adsorption heat is relatively small, and physical adsorption does not require activation energy and can be operated under low temperature conditions. The adsorption effect is reversible, and the molecules adsorbed together will also detach from the solid surface due to the thermal motion of the particles. This phenomenon is called desorption. VOC adsorbents can form single molecule adsorption layers or multi molecule adsorption layers. Because intermolecular forces are universally present, the adsorption effect of VOC activated carbon allows one adsorbent to adsorb multiple substances. However, due to the different properties of the adsorbate (solute), the amount of adsorption also varies. This adsorption phenomenon is closely related to the surface area and pore dispersion of the adsorbent.

The VOC adsorption tower body is designed horizontally and horizontally, and the activated carbon adsorption layer is arranged vertically in multiple zones to increase the contact area between activated carbon and exhaust gas. The front section of the activated carbon adsorption layer is equipped with an extraction type primary filter screen, which can first filter out the particulate matter in the exhaust gas to prevent the activated carbon adsorption layer from being blocked. After meeting the industrial waste emission standards set by the local government, it is treated and then discharged into the atmosphere.

With the rapid development of the economy and the continuous improvement of people's lives, the requirements for the environment are becoming increasingly high. In order to create a suitable living and working environment for humans and effectively protect human life on Earth, the treatment of air and water pollution is particularly important. To meet the requirements of the times and contribute to environmental protection, the simplest and most practical VOC adsorbent is very important.
