The invention relates to inertial filters separating solid and liquid particles from a gas stream, it can be used in the gas, chemical, petroleum and other sectors of the industry where pre-cleaning of gases is required.

The purpose of the invention is to intensify the separation of gases, reducing the hydraulic resistance of the filter.

FIG. 1 shows the inertial centrifugal filter, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 - section B - B in FIG. one; in fig. 4 - section B - B in FIG. one.

The inertial centrifugal filter contains a cylindrical body 1, in which blade vanes 2 are installed. The cylindrical body 1 is connected to a separating body 3 and an outlet nozzle 4. In the separating body 3 a partition 5 is installed with a cylinder 6 opposite to the gas flow which is made in the form of a truncated cone. The partition 5, the perforated partition 7 with a cone 8, the top of which is directed towards the moving stream, together with the separation housing 3 form a gas purification chamber, which communicates with the accumulator (moisture collector) 9 equipped with a drain device m 10 and the waste collection chamber 11 gas cleaning.

Inertial centrifugal filter works as follows.

The gas supplied through the pipeline hits the blade swirlers 2 installed in the cylindrical housing 1. In this case, the gas acquires a rotational motion and hits the perforated partition 7, and a part of the gas that does not hit the vanes hits the cone 8 and all the gas that receives the rotational movement, passes through holes in the separation partition and hits the partition 5, changing the direction of movement. In the cleaning chamber formed by the partitions 5 and 7, the gas is separated (separated), with the liquid and solid particles in the gas along the walls of the gas

3 and partitions 5 and 7 enter the chamber 11 of the accumulator 9 of waste products.

Removal of waste products is carried out with the help of drain device 10. To prevent waste products from entering the gas path when their walls of partition 5 are moistened at the inlet of the cylinder b, an edge in the form of a truncated cone is made. The purified gas leaves 0 through cylinder 6 and outlet 4.

Improvement of gas separation is achieved by installing a cone 8 on a perforated partition 7, which cuts through a gas stream that has not arrived at the blade swirl 2, and is captured by a rotating gas stream, as well as through a cylinder 6, which is opposite to the gas flow in a truncated cone edge which with the surface of the partition 5 form a stagnant zone in the form of 0 annular grooves, due to which waste products do not fall into the gas path, and flow into the chamber 11 of the storage device 9.

A decrease in the hydraulic resistance is achieved due to an incomplete overlap by blade vanes of the flow section of the cylindrical body 1 (Fig. 2 and 3).
