Cyclone separators have been known for hundreds of years, and human beings have been continuously explored and improved to achieve a high separation effect, but the higher the separation effect is, the larger the cyclone separator air pressure difference is, the pressure difference is approximately 1500Pa, and meanwhile, the more and more energy is consumed. Through observation and analysis, the mixture of the material and the gas enters the cyclone separator from the inlet of the cyclone separator to form rotation, and the material is clung to the inner wall of the cyclone separator to sink to the bottom of the cyclone separator under the action of centrifugal force due to the fact that the specific gravity of the material is larger than that of the gas, and the cyclone gas is led out of the cyclone separator through the air outlet cylinder. However, the older cyclone separators have the following problems

1: under the drive of the centrifugal force of the cyclone, the materials slowly sink close to the inner wall of the cyclone separator due to the action of the centrifugal force.

2: the cyclone separator has high wind resistance and high pressure difference due to the opposite directions of the vortex energy of the separator, and the upward vortex gas moves in a spiral state even after entering the air outlet pipe, so that the wind resistance is high, a part of fine dust always passes through the wind hole to reach the air outlet pipeline due to the wind hole, and the separated gas always carries part of dust.
