Description

Diffusion type cyclone separator Technical Field The utility model relates to the technical field of gas separation, in particular to a diffusion cyclone separator. Background The diffusion type cyclone separator is high-efficiency gas-solid separation equipment based on the centrifugal separation principle, has the core advantages that through structural optimization and flow field design, the collection efficiency of the traditional cyclone separator on fine particles is remarkably improved, and the diffusion type cyclone separator is particularly suitable for scenes with strict dust discharge requirements in the industrial field. For example, CN217527868U discloses a diffusion cyclone separator, which comprises a main cylinder body, wherein the main cylinder body comprises an upper cylinder body provided with an air inlet and an air outlet, the upper cylinder body is a conical cylinder, the caliber of the upper end of the upper cylinder body is smaller than that of the lower end of the upper cylinder body, the upper end of the lower cylinder body is connected with the lower end of the upper cylinder body, the lower cylinder body is a conical cylinder, the caliber of the upper end of the lower cylinder body is larger than that of the lower end of the lower cylinder body, the separator further comprises an air cylinder, the air cylinder is arranged in the main cylinder body, an outer cyclone area is formed between the main cylinder body and the air cylinder, an inner cyclone area is formed inside the air cylinder, the air inlet is communicated with the outer cyclone area, the air cylinder is provided with an air inlet at the lower end of the air cylinder and an air outlet at the upper end of the air cylinder, the air outlet is communicated with the air outlet, the air cylinder comprises a cone-shaped air cylinder section, the upper end of the air cylinder section is smaller than the air cylinder section at least, and the air cylinder section is positioned at the air cylinder section at the lower end of the air cylinder section. According to the diffusion cyclone separator, the conical gas collecting section is arranged in the upper cylinder, the outer cyclone region for separation is physically separated from the inner cyclone region for air outlet, but a small amount of dust enters the gas collecting section along with the gas, and the dust removing effect is relatively poor. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide a diffusion cyclone separator so as to solve the problems that a small amount of dust can enter a gas collecting section along with gas and the dust removing effect is relatively poor in the prior art. The diffusion cyclone separator comprises an upper cylinder body and a lower cylinder body detachably connected with the upper cylinder body, wherein a gas collecting section is arranged in the upper cylinder body in a matching manner, a gas collecting inlet at the bottom of the gas collecting section is provided with a filter screen, and an electrostatic precipitator is connected to an exhaust pipe at the top of the gas collecting section.
