Most of the dry cleaning machines used in tetrachloroethylene dry cleaners are machines that can dry in and out, remove solvents and dry, and are equipped with condensation systems to recover dry cleaning solvents. Some models are also equipped with environmentally-friendly carbon tanks to absorb the solvent that is not completely condensed and recover it through adsorption and desorption of activated carbon.
And it will be absorbed in the desorption and condensation of activated carbon, so compared with oil dry cleaning, the problem of volatile organic compounds pollution is not serious.

Advantages and disadvantages of dry cleaning clothes
With the development of chemical industry and clothing industry, clothing fabrics are constantly updated, and many of them need dry cleaning. Dry cleaning generally does not deform clothes, and it is very convenient and popular, but it also has health hazards.
Generally speaking, dry cleaners use high chloride chemicals as active solvents when dry cleaning clothes. This high chloride is harmful to the human nervous system. Long-term exposure to this chemical is likely to lead to kidney cancer.
In the process of dry cleaning clothes, this chemical will be absorbed by the fibers of clothes, and then released into the air from clothes when clothes are dry, thus affecting human health.
