Pressure swing (temperature swing) adsorption separation and purification technology uses the characteristics of gas components that can be adsorbed on solid materials. in the organic waste gas and separation and purification device, the organic waste gas is processed by pressure or temperature changes. After the organic waste gas is adsorbed, it is converted through a certain process to maintain and improve the regeneration capacity of the adsorbent, so that the adsorbent can be put into use again, and then repeat the previous steps, and the cycle repeats until the organic waste gas is purified.
