Abstract

The invention relates to devices for cleaning gases from dropping liquids in various industrial fields and makes it possible to increase the drop drop efficiency. In the body of the drip tray placed a cylindrical swirl and fender trimmed cone. Between the swirler and the truncated cone there are inclined plates on which a portion of the liquid from the moving upward swirling gas flow is deposited. This liquid flows due to the inclination of the plates into the funnel, which serves as the upper base of the swirler. A conical shut-off device is placed above the funnel drainage pipe, which prevents the discharge of liquid from the funnel. Its shape, the location of the tip of the upper lower ends of the plates fixed on the periphery of the funnel, provide additional sedimentation of droplets from the central zone of the stream. The main mass of the pipe passes in the zone of the upper ends of the plates attached to the inner surface of the truncated cone, which provides favorable conditions for the liquid to the lower ends of the plates. 1 hp ff, 3 ill. with S (L 00 1C (CO oo

Description

The invention relates to the field of gas cleaning from a dropping liquid and may find application in various industrial fields.

The purpose of the invention is to increase the activity of the drop-head an.

FIG. 1 shows a drip tray, general view; in fig. 2 shows section A-A in FIG. ; in fig. 3 shows a section BB in FIG. I.

The drift catcher contains a vertical body 1, an inlet confuser 2 mounted inside it with a myogolopatny cylindrical swirler 3. The swirl 3 has an annular lower base 4 and a upper base in the form of a funnel 5 with a drain pipe 6. The end of the nozzle 6 is brought into the annular pocket 7. In the annular space between the housing 1 and the swirler 3, a fender trimmed cone 8 is installed, the lower base of which is located below the base 4 of the swirler 3. In the annular space between the truncated cone 8 and the swirler 3, inclined plates 9 are marked between which channels of variable cross section are formed, narrowing downwards. The plates 9 with the lower end are fixed on the periphery of the funnel 5 and the upper end on the inner surface of the truncated cone 8. Above the funnel 5 there is a conical cut-off 10, the top of which is located above the lower end of the plate 9 and the base diameter is larger than the diameter of the drain nipple 6. Case 1 it is equipped with drain fitting 11 and outlet 12.

The device works as follows.

An upward flow, for example, after a wet filter containing a dropping liquid, enters the droplet separator through the inlet confuser 2. The passage through the vortexer 3, the gas flow acquires a rotational motion. Due to centrifugal forces, the droplets are dropped onto the truncated cone 8, forming a rotating turbulized film of liquid, part of the liquid from which flows under the force of gravity into the annular pocket 7, and the rest is entrained by the gas flow and deposited on the plates 9. Thanks to their inclined position, the liquid flows into the funnel 5 and is led out through the pipe 6 into the pocket 7. Under the conical cutter 10, the base diameter of which is larger than the diameter of the discharge tube 6, a hydrodynamically quiet zone is formed, which is exists eliminate re-entrainment liquid present in the cup. The conical shape of the shutter and the location of its top, lower than the lower end of the plates 9, allow liquid droplets to precipitate, which are blasted into the central zone by turbulent pulsations of the gas flow.

The ascending gas flow passes the zone of the plates 9 predominantly in their peripheral area due to the fact that the channels between them narrow downwards. With this in

In the lower part of the channels, the velocity of the gas is insufficient for transporting the liquid upwards and conditions are provided for the liquid to flow down the inclined plates 9 without disrupting the liquid. During the passage: gas drops in the peripheral zone of the plates 9 cause the droplets to fall off, which reach the walls of the housing 1 and flow down into the pocket 7. Because the lower base of the truncated cone 8 is located below the base 4 of the swirler 3, a dynamically stabilized discharge is provided fluids into the annular pocket 7. The gas exiting from the channels between the plates 9 expands in the upper part of the volume of the housing 1. In this case, it is redistributed to the outlet nozzle 12 in such a way that the core

0 the swirling flow, which is formed due to the same direction of the plates 9, is displaced from the wall of the housing 1. This eliminates wave formation in the liquid separated into the walls of the housing 1 and, therefore, secondary entrainment.

The outlet 12 is located close to the inclined plates 9. The gas freed from the liquid droplets through the outlet 12 is removed from the drift catcher.
