SUPPORT AND DISTRIBUTION PLATE Russian patent published in 2021 - IPC B01J8/18 B01D3/20 B01D24/36 

FIELD: water treatment, chemical industry.

SUBSTANCE: invention relates to support and distribution devices for devices with a fluidized bed of solid particles used for the separation of liquid-solid or gas-solid systems, namely, to the design of caps for poppet columns, and can find application in drinking water and wastewater treatment plants, in the chemical, petrochemical, food, pharmaceutical and other industries. The support and distribution plate for devices with a fluidized bed of solid material contains a base in the form of a disk, equipped with a hole for unloading the contacting load, and drainage caps placed on the surface of the disk, installed taking into account the phenomenon of “natural slope” on the inlet pipes in such a way that the water input is performed above the lower hole of the cap to a height greater than a layer of solid granular material can rise after its deposition, and equipped with devices for fixing the caps. In the lower part of the caps pressed against the disk, slots are made, and the caps themselves are installed on the disk in such a way that their slots are directed in one direction along the circumference of the disk. The slots may be slits or one or more holes located on one side of the cap, which together make up from 1/30 to 1/2 of the circumference of the cap. On the opposite side of the slots, there are slits or holes with a passage section of no more than 15% of the main holes.

EFFECT: increasing efficiency of the devices by 15-25%, reducing their height by 10-15%.
