Description

Crushing cutter module and fluid crushing device
Technical Field
The invention relates to the technical field of crushing equipment, in particular to a crushing cutter module and a fluid crushing device.
Background
Fluid is a generic term for liquids and gases. Currently conventional equipment that can be used to refine particles in a fluid is grinding equipment, high pressure homogenizers, high shear homogenizers, and the like. Among them, the grinding equipment is most widely used. The refining principle of the grinding equipment is that the processed materials such as liquid, slurry or powder are mixed with grinding materials such as ceramic balls and the like for grinding, and the grinding materials grind the materials more and more finely.
However, the abrasive media of conventional grinding methods and apparatus mostly contaminate the fluid, i.e., the product, during the grinding process. Especially, when the grinding device is used for treating blue algae-containing liquid, blue algae can be crushed, so that the cell wall of the blue algae is broken and cannot become food for other aquatic animals, and the biological chain is broken, so that the ecological system cannot reach a new balance when being hit newly. Meanwhile, the cell wall of the blue algae is broken, so that toxins (such as microcystins) in the cells of the blue algae flow out, secondary pollution of water is caused, and hidden danger is brought to human health.
