Description

The invention relates to ainnapaTaM chemical technology and can be used in absorption and rectification processes.

A countercurrent multistage contact apparatus is known, which includes a cylindrical body and located inside it by a helix software that partially overlap each other contact elements in the form of sectors attached to a central tube.

The proposed apparatus is characterized in that the contact elements are attached to the walls of the housing and are made in the form of a horizontal duct of a rectangular section attached to it from one end of the inclined duct, and from the other to a semi-circular cup with openings on the side wall and placed under it disk with a threshold. This increases the productivity of the device.

The drawing shows the proposed apparatus in a perspective view, a General view.

In the housing / apparatus, contact elements are arranged along a helical line, made in the form of a horizontal duct 2 of rectangular cross section, to which an inclined duct 3 is attached to the helium end, and a semicircular cup 4 with openings 5 on the side wall from the other end. Under the box 2 times. Placed disk 6 with a threshold of 7.

Contact elements attached to the strips 8, welded to the body.

Apnarat works as follows. The steam entering from the bottom moves up along the channel of the angular section formed by the adjacent turns of the contact elements. The liquid supplied to the upper part of the air unit is directed into one of the receiving pockets 9 formed by the housing wall /, the inclined duct 3 and the strip 8, and then along the inclined and horizontal ducts of the element enters the cup 4. .zhet flow into the steam is simple: the area of the axis of the apparatus. Vapor stream passing at high speed past the holes, liquid, splits into droplets and, under the action of centrifugal siVTbi, throws it onto the walls of the body, where it re-enters the spacecraft one turn lower. Thanks to such a movement; 1 way, there is a counter-current in the whole apparatus and good contact when it moves from the center to the wall of the case.

Part of the liquid during the flight falls on the plane of the elements, so that it can move in the form of a film in the same direction with the para-flow, which leads to j drift. To prevent this from occurring, each element is installed one under

3

others are left with a radial gap of 5–10 mm in height, through which a small part of the steam passes towards: the vortex flow. The counter flow contributes to a good dispersion of the liquid, turbulizacin of steam jets and significantly reduces entrainment.

The subject is invented and

Countercurrent multi-stage contact apparatus, including cylindrical

the housing and the contact elements partially overlapping one another along a helix, characterized in that, in order to increase productivity, the contact elements are attached to the walls of the housing and are made in the form of throats, of the zonal box of rectangular cross section attached to it one end of an inclined duct, and on the other, a semicircular cup with holes on the side wall of a disk with a threshold placed under the lnm.
