Abstract

The invention relates to instrumentation of mass exchange processes in the gas-liquid-solid system and can be used in the chemical, pharmaceutical, energy and other branches of the process in the process of regeneration and washing out of ion exchangers, extraction, and targeting. The purpose of the invention is to reduce gas consumption and reduce wear of the particles and the body by stabilizing the mixing conditions of the interacting phases. The mass-exchange apparatus includes a housing 1 inside which sectional partitions 2 are installed, drainage 6, nozzles 11 fixed in slots 13 of trays 14, a system of forced fluid supply, covers 15 with circulation airlifts 16 mounted obliquely. The lower edges of the housings T5 and circulating airlifts 16 are made oblique, and the bevel angle of the lower edges of the housings 15 is less than the bevel angle of the lower edges of the circulating airlifts 16. 2 a, p. f-ly, 3 ill. i (L

The invention relates to instrumentation of mass exchange processes in the gas-liquid-solid system and can be used in chemical, pharmaceutical, energy and some other industries during the regeneration and flow of ion exchangers, extraction, extraction.

The purpose of the invention is to reduce gas consumption and reduce wear of the particles and the body by stabilizing the mixing conditions of the interacting phases.

FIG. 1 shows a mass transfer apparatus, top view; FIG. 2 is a section A-A in FIG. 1j in fig. 3 - section bb in fig. 1.

The mass transfer apparatus includes a housing 1, inside of which partitioning partitions 2 are installed, dividing its working volume into a series of sections, each of which contains airlifts 3. and suspension circulation pipes 4 with removable clamps 5. Each partition has a drain 6 in the form of a grid the size of which is less than the lower limit of the diameter of solid particles, as well as fittings 7, nozzles 8 and airlifts 9. Sections - include nozzles 10 and nozzles 11 located on slopes 12 fixed in slots 13 made in trays 14 passing through partitions 2 6 and drains connected to the casings 15, the circulation air lift 16. The lower edges of the circulation air lift 16 and the housings 15 vypolnents beveled, with the bevel angle of the lower edges of the housings 15 is less miter lower edges the circulation airlifts 16 mounted with an inclination. The gas phase is supplied to the circulating airlift 16 with the aid of a choke 17, into the airlift 3 with a choke 18, and into the airlift 9 with a choke 19.

The mass transfer apparatus works as follows.

Through the drainage 6, the liquid phase enters the nozzle 8 of the corresponding section and then goes to the airlift 9, where gas is supplied through the nozzle 19, after which the liquid phase is transported to the sprayer 11. At this,

The sheath part of the liquid is sprayed and irrigates the dried granulated mass, and the excess volume of liquid flow flows down the slope 12. The resulting slurry moves along the tray 14 and enters the casing 15, in the lower part of which it mixes with the circulating stream, after which it rises along the airlift 16 and enters the volume section. The bevel of the lower edge of the circulating airlift 16 provides automatic capture of the suspension, and the bevel of the lower edge of the casing 15 helps to stabilize the performance of the circulating airlift 16. When the level of the suspension in the section increases, the excess is directed to the airlift 3. Trap 14, and flushed into it with a stream of fluid. Similar processes take place in other sections of the apparatus. After the passage of the working volume, the interacting phases are removed from the body of the mass transfer apparatus,
