Method of separating and extracting particles from filter material base, device and system

The invention relates to a pretreatment method for a particle filter material sample and device, in particular to a method of separating and extracting particles from a filter material base, device and system, so as to solve the problems that the existing washing method lacks specific implementation details, and when the existing washing machine is used as a separating device for washing and separating, the loss of particles is large, the separating efficiency is low, and washing by using an organic solvent can not be realized. The method is characterized by comprising steps: 1, a filter material sheet after sampling is put in a separating device, and water and a surfactant are added, wherein the outer layer of the separating device has a barrel-shaped structure, the inner layer is provided with multiple holes and can perform autorotation; 2, washing is carried out, and turbid liquid flows out; 3, dehydration is carried out and residual turbid liquid flows out; 4, the turbid liquid flowing out in the second s
