Description

 The invention relates to the field of air purification from dry dust and can be used in any sectors of the economy.

 The purpose of the invention is to increase the efficiency of dust collection by providing multiple purging of the cleaned air.

 The drawing shows a dust collector, in section.

 The dust collector comprises a housing 1 with outlet pipes 2 and 8. The inlet pipe 3 is located inside the housing 1 coaxially with it and is made with diffuse 4, cylindrical 5 with holes 6 on the surface and 7 confuser sections connected in series. The holes 6 are located on the surface of the cylindrical section 5 in a checkerboard pattern.

 The ratio of the total area of the holes 6 and 7 and the cross-sectional area of the cylindrical section 5 is 2.5.

 The operation of the device is as follows.

 The dusty air flow is directed through the inlet pipe 3 from top to bottom into the diffuser section 4, then it moves to the cylindrical section 5 with round holes 6 arranged in staggered rows along the cylinder generatrix, from where the air is evenly distributed over all holes 6 and leaves perpendicular to the initial movement in the form jets that ensure the contact of dust particles with the wall of the cylindrical housing 1. Dust particles are poured into the cone of the housing to the exhaust pipe 2, and those particles that continue with the air flow path into the upper portion of the housing are affected upstream and adjacent jets returning the remaining dust particles back to the wall. Reflecting from the wall of the housing 1, the jets are attached to the total air flow, being subjected to repeated purging while passing to the outlet pipe 8.

 All dust particles contained in the air are in contact with the wall of the housing 1, and the continuously incoming stream of air jets prevents them from flying away from the wall of the housing 1 and facilitates directed movement down the wall of the housing 1 through the pipe 2, which removes dust into a sealed discharge hopper (in the drawing) not shown).

 The system of continuous multiple purges under the influence of air jets creates a complete air purification from suspended dust particles. The purified air through the pipe 8 is released into the atmosphere.
