Abstract

The invention relates to the field of apparatus for carrying out processes of heat and mass transfer, in particular for the process of gas absorption by liquid absorbents, as well as for carrying out dust collection processes, and can be used in chemical and other industries and intensifies the processes through the organization of countercurrent motion phases and improve fluid dispersion. The apparatus includes a housing with phase inlets and outlets, installed in pairs in the same plane and dividing the device into chambers upper and lower vertical partitions, inclined partitions connected to them with bortovins, forming channels along the gas paths that increase along the gas flow. This upper vertical partitions are made with a horizontal slit and with a hole, and the lower - connected to the bottom of the case. The slots and openings of the upper partitions are installed with the possibility of adjusting the cross section, 1 hp. f-ly, 4 ill. (Oh cl

 Liquids FIG.

. The invention relates to apparatus for carrying out heat and mass transfer processes, in particular for the process of gas absorption by liquid absorbents as well as for carrying out dust collection processes, and can be used in chemical industry, non-ferrous and ferrous metallurgy, and in other industries,

The purpose of the invention is to intensify the processes by organizing an anti-phase movement and improving the dispersion of the liquid.

FIG. 1 shows a schematic representation of the proposed heat and mass transfer apparatus, the section in FIG. 2 — node I in FIG. one; in fig. 3 shows section A-A in FIG. 2; in fig. 4 is a view B in FIG. 2.

The apparatus includes a housing 1, in which the upper 2 and lower 3 vertical partitions are installed in pairs in the same plane, dividing the apparatus into chambers 4. Inclined partitions are connected to the vertical bridges: upper 5 and lower 6, with flanges 7. Contact channel The walls, formed by inclined partitions and bortovins, are placed on levels that increase along the gas flow. The upper vertical partitions are provided with horizontal slots 8 and located at the level of the gap between the bead and the wall of the body of the holes 9. The slots and holes are located at the same level of the upper end of the gas along the lower vertical partition. Lower vertical partitions 3 are connected to | bottom of the housing 1-. The latter is supplied with fittings 10 and 11 for the introduction of liquid and gas, respectively, and fittings 12 and 13 for their removal. The adjustment of the cross section of the slit 8 and the hole 9 is carried out, for example, by using the bottom plates 14 and 15.

The apparatus works as follows.

Gas enters through shtutucer 11 of housing 1, and the passage through the contact channels from the chamber to the chamber leaves the housing 1 through fitting 13. Fluid is supplied through fitting 10. Flow from chamber into chamber through openings 9, liquid is withdrawn through fitting 12. Liquid serves in an amount to capture the active component of the gas, taking into account possible evaporation and condensation processes. Placement of the upper ends

The lower vertical partitions are not arbitrary, since the placement of the liquid level in this chamber above the slit 8 in the upper partition 2, to which the upper inclined partition of the channel passing the gas into this chamber is connected, should ensure the formation of a hydraulic seal preventing the gas from passing through the slit. previous along the gas chamber. The level in the chamber is regulated by the cross-sectional area of the opening 9. Through the slit 8, the liquid flows from this chamber into the previous one, is completely picked up by the gas flow in the channel, since the slit is located just above the bottom of the channel, and returns to the same chamber. Thus, countercurrent conditions are fully formed. The amount of fluid entering the channel is controlled by the cross-sectional area of the slot 8 itself. Hole 9 is located outside the channel zone, therefore the fluid flowing from the chamber to the chamber does not undergo active contact with the gas.

The use of the proposed apparatus as a gas-lift device in a sulfuric acid cooling system in direct contact with an organic evaporating refrigerant (fraction) during contact has an economic effect at a level of 50,000 pub. on the apparatus
