Specifically, when the treatment device for the large air volume and low-concentration organic emission is used:

the waste gas has large air quantity and low concentration, and the offset printing waste gas contains polymers (such as epoxy acrylate and the like), and the dry filtration and the activated carbon adsorption treatment are adopted in consideration of energy consumption and investment cost, so that the waste gas can reach the standard and can be discharged after the treatment.

After the activated carbon is adsorbed for a certain time, high-temperature hot gas can be used for desorption, and the organic solvent adsorbed in the activated carbon is desorbed and sent to RTO for treatment. The activated carbon can be continuously reused after desorption. Greatly reduces the operation energy consumption and the maintenance cost.

The working principle of the activated carbon adsorption equipment is as follows: the active carbon is a kind of very fine carbon granule, which has very large surface area and also has finer pores, namely capillaries. The capillary tube has strong adsorption capacity, and the carbon granules have large surface area, so that the carbon granules can be fully contacted with gases (impurities), and the gases (impurities) can be adsorbed when contacting the capillary tube to play a purification role. The essence of activated carbon adsorption is that the organic solvent in the low-concentration large-air-volume waste gas is adsorbed into the activated carbon by utilizing the characteristic of activated carbon adsorption.

The active carbon desorption working principle is as follows: activated carbon desorption is the reverse of adsorption. The operation process is that the adsorbed component is saturated and separated out from the adsorbent, and the adsorbent is regenerated. I.e. the process of the substances adsorbed on the interface escaping the interface to re-enter the bulk phase under certain conditions, also called desorption.

The activated carbon regeneration is to reactivate the activated carbon after the activated carbon with saturated adsorption is treated under certain conditions. The activated carbon has been used in large quantities in the aspects of environmental protection, industry and civilian use, and has achieved considerable effect, however, after the activated carbon is replaced after saturated adsorption, the use of activated carbon adsorption is a physical process, so that the impurities in the used activated carbon can be desorbed by adopting high-temperature steam, and the original activity of the impurities can be recovered, so as to achieve the purpose of reuse, and the method has obvious economic benefit. The regenerated active carbon can be continuously reused and regenerated.

The activated carbon regeneration is to reactivate the activated carbon after the activated carbon with saturated adsorption is treated under certain conditions. The desorption method of the activated carbon comprises the following steps: the temperature is raised for desorption, the adsorption quantity of the substance is reduced along with the rise of the temperature, the temperature of the adsorbent is raised, and the adsorbed components can be desorbed, the method is also called temperature-variable desorption, and the temperature is periodically changed in the whole process.
