A dry cleaning machine generally consists of several parts, including a blower, a segmenter, a classifier, a dust collector, an induced draft fan, an electrical control cabinet, etc. It completes the dry cleaning work through the action of a dry cleaning solvent under mechanical force. There are two oil cylinders under the oil dry cleaning machine, and a certain amount of dry cleaning soap oil needs to be added to the cleaning solvent during operation. When soap oil is added to the dry cleaning system, the soap oil molecules will affinity the water molecules with the dry cleaning oil molecules, so that the water will be evenly distributed in the dry cleaning oil, thereby dry cleaning clothes. Due to the absence of free water, clothing will not shrink, wrinkle, darken, or discolor, and the presence of water molecules can remove water-soluble dirt.
The principle of a tetrachloroethylene dry cleaning machine is similar to that of a petroleum dry cleaning machine, except that its dry cleaning solvent is tetrachloroethylene, which has a higher cleaning efficiency. During work, tetrachloroethylene changes from liquid to gas, which then enters the corresponding device and becomes liquid again, thus achieving the process of dry cleaning and purification of tetrachloroethylene.
