Power type filtering method

Abstract

This invention provides a filter method for light substances under impetus, such as smoke, smog poison substances, which is characterized by the following: under the impetus, the high speed rotary shooting needle to shot down the smoke and powder; then under the centrifugal force, damping the smokes to the outer shell inner wall and flowing to the drainage under gravity action.

Description

Technical field [0001] The invention relates to a filtering method capable of filtering light substances under the action of power, especially a dynamic filtering method capable of filtering harmful substances in oil fume, dust gas, air and the like. It belongs to the technical field of environmental protection. Background technique [0002] At present, the known filtering method is actually a resistance filtering method. Generally speaking, no active force is required. As long as the flow-blocking material smaller than the density of the material to be filtered is used, the material to be filtered out will be blocked under the condition of a certain thickness. It is impossible to pass through the blocking material, thus achieving the purpose of filtration. When the material to be filtered is small, the blocking material will be smaller and thicker, and the resistance of the blocking material will be greater. The existence of resistance actually consumes the energy of the m...
