SU137484A1 - Device for trapping alcohol vapor from carbon dioxide released during the process of obtaining alcohol - Google Patents

Description

Devices for capturing alcohol vapor from carbon dioxide released during the alcohol production process are known as a vertical cylindrical column, to which water is brought from above, moving from top to bottom countercurrent to the flow of carbon dioxide brought from the bottom of the column.

These devices do not sufficiently completely trap alcohol vapors because the conditions of contact between absorbing water and carbon dioxide are unsatisfactory, and in addition, absorbing water is heated from carbon dioxide (entering the device with a temperature of about 30 °), which reduces its absorbing ability to.

In the proposed device, in order to increase the efficiency of the trapping process, a system of tubular elements is installed inside the column between the upper and lower lattices, washed outside with cold running water, and a cylindrical nozzle is mounted above the upper lattice of tubular elements. -water pipes and a tube covered to the top with a cylindrical cap for transporting carbon dioxide.

The drawing schematically shows a longitudinal section of the described device.

The device is made in the form of a vertical cylindrical column 1, provided with upper 2 and lower 5 gratings and a system of tubular elements 4 located between these lattices.

A cylindrical nozzle 5 is mounted above the upper p-section 2, inside of which several horizontal sieves 6 are fixed, a vertical pipe 7 installed overflows for water and the pipe 9 is covered with a cylindrical cap 8 of pipe 948482 to move carbon dioxide.

Carbon dioxide containing alcohol vapor enters column 1, goes through the distribution bubbler JO, rises up through the system of tubular elements 4, pipe 9, goes further under the cap 8, from there through the water layer and the screen 6 goes into the cavity below the top wall 5 and sucked out of it through the pipe.

Water intended for absorption of alcohol vapor enters the upper part of the column / in nozzles 5. When carbon dioxide gas flowing through it through pipe 9 passes through it, it partially absorbs alcohol vapors and through overflow pipes 7 enters the upper part of the system of tubular elements 4 from where, through special nozzles, it is distributed by the film over the inner surfaces of the tubular elements 4 and then goes down (countercurrent to the rising carbon dioxide) and is poured out of the device through shtucer 12. From the outside, the system of tubular elec ENTOV 4 omyvaets cold running water, whereby water in the form of a film inside trzbchatyh elements 4 horoscho pair absorbs alcohol from carbon dioxide, moving countercurrently thereto.

Subject invention

A device for trapping alcohol vapors from carbon dioxide released during the production of alcohol, made in the form of a vertical cylindrical column, to the top of which water is brought, moving with a countercurrent to the flow of carbon dioxide brought to the bottom of the column, characterized by that, in order to improve the efficiency of the trapping process, a system of tubular elements was placed inside the column between the upper and lower lattices; it was washed with cold running water and above the upper lattice mounted cylindrical orifice within which it is fixed a plurality of horizontal sieves vertically arranged pipes for water and covered with a cylindrical top cap tube for transferring carbon dioxide.
