Abstract

The invention relates to a device for separating a liquid from a gas-liquid stream and makes it possible to increase the efficiency of separating a dropping liquid by eliminating re-entrainment and stabilizing the flow of the separated liquid. The liquid separator contains a housing 1, installed in a staggered vertical separation elements of a single profile, made in the form of a central longitudinal plate 2, to the edge 3 of which wave-shaped plates 4 are attached on the flow inlet side, forming open collecting cavities facing the entrance flow. Each wave plate is formed by the junction of two arcs of radius R, the point of contact of which lies on the center line, which is the diagonal of the rectangle. In the edge facing the exit direction, an arcuate plate 7 is attached, the entrance to the cavity of which is directed along the flow direction and limited by an opening angle of 60 °. The arcuate plate of each previous separation element enters flush into the collecting cavity of each successive element, forming liquid traps inaccessible for the flow, with the longitudinal step of the sedimentary elements being 2 2 sludge. 3 R2, and transverse - 4R.

The invention relates to devices for separating a liquid from a gas-liquid stream by precipitating it under the action of inertial forces and changing the direction of motion, and can be used in various branches of the national economy related to the purification of gases from liquids.

The aim of the invention is to increase the efficiency of dropping liquid separation by eliminating re-entrainment and stabilizing the flow of the separated liquid.

Figure 1 shows the device, a general view; figure 2 is a fragment of the device.

The liquid separator contains a housing 1, installed in a staggered vertical separator elements of a single profile, made in the form of a central longitudinal plate 2, to the front edge 3 of which are attached wave-shaped plates 4, which form open pointed collecting cavities 5 facing the flow to the flow. Each wave plate 4 is formed by the conjugation of two arcs of radius R, the point of contact of which lies on the center line, which is the diagonal of the rectangle with the sides of Pu2

and limited to smaller ones

sides of the rectangle. An arcuate plate 7 of radius R / 2 is attached to the trailing edge 6, the entrance to the cavity of which is directed downstream and limited by an opening angle of 60 °. With the mutual arrangement, the arcuate plate 7 of each previous separation element enters flush into the pointed collecting cavity 5 of each subsequent element, forming liquid traps 8 that are not accessible to flow, with the longitudinal step of the repair elements being R2. and cross - 4R.

The separator works as follows.

The horizontal gas-liquid flow enters the device and wavyly passes through the channels between the rows of separation elements. As a result of the action of inertial forces and a change in the direction of movement, the liquid is separated from the gas without the formation of splashes and drops. Separating the liquid along the inner surface of the wavelike plates 4 and the outer surface of the arcuate plates 7, through the slit openings 9 enters the traps 8 and, being protected from the influence of the main flow, flows down to discharge.

After passing through the bag of separation elements, the gas is completely freed from the liquid and leaves the device.

Separation elements made in the form of longitudinal plates with undulating and arcuate plates on their edges forming liquid traps prevent direct and diagonal flow through the device, and liquid traps inaccessible to the main flow create conditions for efficient liquid separation without splashes and drops. ensure the stability of the flow of the separated liquid and the elimination of secondary entrainment,
