Description

(54) CENTRIFUGAL SEPARATOR

one

The invention relates to a process for cleaning dusty gas streams containing suspended, predominantly solid, fine particles, and can be used in the chemical, metallurgical, mining and other industries.

A centrifugal separator with swirls of gas flow in the inlet pipe and a groove, which forms a multiple-use screw channel 1 in its output part, is known.

Known centrifugal separator containing a vertical case, on the inner surface of which is made grooves, forming a multiple screw channel, the input pipe of the dusty gas, located tangentially, the branch pipes of the gas outlet and the captured product.

Known centrifugal separators have an inlet with a swirler and a groove in the output part, forming a multiple screw channel, a housing, an outlet. The separation of gas and solid particles occurs when coming out of the outlet in which the gas flow acquires a spiral motion. Under the action of centrifugal force, heavier solid particles are thrown against the walls of the body.

and is withdrawn from it from below, and the purified gas enters and is discharged through it | 2.

The disadvantages of the known separators are the complexity of the design of the inlet pipe with a swirler and a groove in the outlet part, insufficient cleaning efficiency of the gases in the separator due to the possibility of secondary entrainment of the separated particles.

Q The purpose of the invention is to increase the efficiency of gas purification by preventing re-entrainment of product particles.

This goal is achieved by the fact that in a centrifugal separator containing a vertical casing, on the inner surface of which there are grooves forming a multiple-use screw channel, a dusty gas inlet fitting located tangentially, a gas outlet and a captured product

2Q gas is installed at an angle to the axis of the body, equal to the angle of inclination of the screw groove. The drawing shows a centrifugal separator, section.

The separator includes a housing 1 with a groove 2 forming a nose on the inside

Claims (1)

Claim A centrifugal separator containing a vertical casing, on the inner surface of which grooves are formed, forming a multi-helical channel, a dusty gas inlet pipe located tangentially, gas discharge pipes and a captured product, characterized in that, in order to increase the efficiency of gas cleaning by preventing secondary entrainment of particles product, the gas inlet pipe is installed at an angle to the axis of the housing equal to the angle of inclination of the screw groove.
