KOCHETOV'S VERTICAL ADSORBER Russian patent published in 2015 - IPC B01D53/02 

FIELD: machine building.

SUBSTANCE: in vertical adsorber containing a cylindrical casing with cover and bottom, in cover the following equipment is installed: loading hatch, nozzle for input mixture with distributing mesh, nozzle for steam release during desorption, and nozzle for safety valve; at that at joint between cover and casing there is a stiffening ring, and in middle part of the casing on the support ring beams with supports are installed, they support the fire grate with arranged gravel bed; at that the adsorbent bed is located between the gravel bed and mesh with weights preventing the adsorbent removal during desorption; the spent adsorbent is unloaded via the unloading hatch installed in the casing, and in the bottom the bubbling chamber and inspection hatch with nozzle for condensate drainage and water supply are installed; the bubbling chamber is made having toroidal shape and is secured on the bottom cone surface using bracings, at that perforation ratio of the chamber toroidal surface is within optimal range: K=0.5…0.9, and nozzle for cleaned gas removal is located on the bottom cone surface; that adsorption and desorption are performed at the following optimal ratio of the vessel elements: ratio between height H of cylindrical part of casing to its diameter D is in optimal range: H/D=0.73…1.1; ratio between height H of cylindrical part of casing to its wall thickness S is in optimal range: H/S=220…275; H₁ and height H of the cylindrical part of casing to is in optimal range: H₁/H=0.22…0.55; ratio between height of adsorbent bed H₁ and height H₂ of gravel bed is in optimal range: H₁/H₂=5.0…12.0, and adsorbent is made as a cylindrical ring with two hemispherical surfaces being fixed on the side surface of the adsorbent opposite each other so that diametral planes of the hemispheres coincide with the upper and lower bases of the cylindrical ring, and the vertices of the hemispherical surfaces are ay the ring axis and turned to each other.

EFFECT: invention increases degree of gas flow cleaning of target component and dust.
