Its working principle is mainly based on the mechanism of physical filtration or chemical adsorption. In terms of physical filtration, the filter material of the dry oil removal filter usually has a certain pore size, which can prevent larger oil droplets and solid particles from passing through, achieving physical separation. In addition, through the fiber structure of the filter material, it can capture and concentrate smaller oil droplets and floating foam to form larger oil droplets, which is convenient for further separation and removal.

[0003] At present, the dry oil removal filter in the prior art mainly includes a shell and a filter layer, and the filter layer is installed inside the shell. The liquid enters the shell from the water inlet and is discharged from the water outlet. When the liquid passes through the shell, it is de-oiled by the filter layer installed inside. The liquid passing through the filter is mainly de-oiled by the filter layer installed in the shell. The pore size and distribution of the filter material and the number of filter layers affect the overall oil removal and filtration effect of the device. The existing method of installing the shell and the filter layer as a whole is not easy to replace and disassemble the filter layer.
