Description

The invention relates to heat and mass transfer equipment of chemical technology, and more specifically to rotary disk reactors for carrying out the reaction in gas-liquid-solid particles systems, and can be used in the chemical industry.

The purpose of the invention is to increase the reliability of the reactor.

The drawing shows the reactor section,

The reactor contains a vertical cylindrical body 1 with a lid 2.

Inside the housing 1, a number of fixed perforated annular discs 3 are attached to the top cover 2, spaced by sleeves 4, mounted on rods 5, fixed in nozzles 6 by retaining rings 7, fixed bead sleeves 8, threaded fasteners 9 and closed sealing caps 10. On the shaft 11 mounted perforated disks 12 and the top 13 and bottom 14 of the support. A fixed cup 17 is fastened to the housing 15 of the bearing 16, covered by a hydraulic cap 18, the lower edge 19 of which repeats the shape of the end face of the sleeve 20 and is impeller-shaped. The reactor is equipped with a nozzle 21 for inlet and a nozzle 22 for the coolant outlet, a nozzle 23 for the inlet mixture, and nozzles 24 and 25 for the inlet and outlet of the gas, respectively. For discharge of the finished product, a pipe 26 is provided. And for supplying a lubricant-shut-off agent, a pipe 27,

The reactor operates as follows. The first is served: cooling in the housing 15 of the bearing 16 through the pipe 21, the lubricating and locking agent through the pipe 27 and the coolant into the heating jacket of the housing 1, The initial reaction suspension is poured into the housing 1 through the pipe 23 to the set level. The shaft 11 with the disks 12 is driven into rotation and the gas is fed through the nozzle 24. A reaction with recrystallization occurs. Recrystallization conditions

depends on hydrodynamic and thermal conditions. Perforated multidirectional areas on the disks 12 create additional circulation of the working medium, which creates a favorable hydrodynamic environment. The unloading of the apparatus is carried out by draining the products with the rotating shaft 11 with the discs 12 through the nipple 26. When the apparatus is operating

the lubricating shut-off agent through the landing gap between the shaft 11 and the bearing 16 rises into the gap between the shaft 11 and the cup 17, and then gets between it and the rotating cap 18, where the centrifugal effect allows you to create a pressure in the lubricant-shut-off agent that prevents the penetration of the working medium in the bearing. This creates a reliable hydrodynamic valve.
