Description

The invention relates to the design of devices for carrying out the processes of absorption and distillation, and can be used in gas and oil refineries. battling and related industries.

The aim of the invention is to increase the clarity of separation of mixtures.

The drawing shows schematically a mass transfer apparatus, a longitudinal section.

The mass transfer apparatus contains an outer casing 1, an inner casing 2 with contact devices 3 placed in it, a horizontal partition 4 dividing the outer casing into upper and lower parts, and gas inlet pipes 5 and 6 corresponding to the outer and inner housings. The mass transfer apparatus is provided with a tube 7 connected to the upper and lower parts of the housing. Gas inlets 5 and 6 communicate with each other and with

lower part of the outer casing. The breakdown of droplets and liquid films from a mass transfer device is equipped with transfer devices in the transition mode by the 8-way liquid inlet pipes, me. Reduction of liquid entrainment at the time of 9 and 10 of the liquid output, 11 output m of the transition from one flow to the other gas and dampers 12. The lower ends of the goy increase the clarity of the pipe 9 and the pipes 7 are located below the separation of mixtures and reduces the average

the upper cut of the pipe 10.

Mass transfer apparatus operates as follows.

The gas is fed through the pipe 5, and the liquid through the pipe 8. The gas fills the lower part of the outer casing 1 and enters the pipe 6 ,. The gas then rises through the contact devices 3, enters the upper part of the outer housing, passes through the baffles 12 and exits through the pipe 11. The liquid from the pipe 8 flows down through the contact devices 3, where mass exchange with the gas takes place. Then the liquid flows out of the pipe 9 and fills the lower part of the outer case to the level of the upper end of the pipe 10. From the lower part of the body 1, the liquid enters the pipe 7.

The liquid carried by the gas from the contact devices 3 collects on the bump stops 12, from where it flows down to the horizontal partition 4 and enters the pipe 7.

With a sharp stepwise increase in gas flow through the nozzle 5, the pressure drop between the upper and lower parts of the outer casing increases, the liquid from the lower part of the casing 1 is forced into the pipe 7 and the volume of gas in the lower part of the outer casing increases. This leads to a smoothing of the stepwise change in the rate of gas flow through the contact devices 3. With a decrease in the gas flow through the nozzle 5, the smoothing of the stepwise change is also achieved.

gas velocity due to the movement of fluid from the hydraulic seal into the lower part of the housing 1.

Thus, the set of structural differences proposed

mass transfer apparatus provides smoothing of stepwise changes in gas flow rate and pressure drop for contact devices of the inner case. It prevents the accumulation

in time loss of the liquid phase. The invention includes a mass transfer apparatus comprising an outer case, an inner case with contact devices placed in it, a horizontal partition dividing the outer case into upper and lower parts, gas inlet nozzles and inlet and outlet nozzles for the outer and inner cases. In order to increase the clarity of separation of mixtures with abrupt changes in gas flow rate due to a decrease in liquid entrainment during the transition from one flow to another, it is equipped with a pipe connected to the upper and lower The outer parts of the outer housing, wherein the gas inlet nozzles of the outer and inner shells are interconnected with each other and with the lower part of the outer housing, and the lower ends of the pipe and the nozzles for removing the liquid from the inner housing are located below the upper edge of the outer fluid outlet nozzle Circulation 656 Subscribe®
