Gas adsorption and concentration device

Abstract

PROBLEM TO BE SOLVED: To provide a gas adsorption and concentration apparatus, feeding desorption air having a temperature near a boiling point of gas to be treated when high boiling point material having a boiling point about 250° is contained in the gas to be treated or high boiling point material is generated due to polymerization in adsorption, and treating gas even if it contains an organic solvent invading silicone rubber elastic material. SOLUTION: The apparatus includes a fan-shaped seal body 5 constituting a desorption zone 4, wherein the seal body 5 includes a pair of radial seals 6, 7, an arcuate outer peripheral seal 9, and an inner peripheral seal 8. These seals are formed of sheets made by covering glass cloth with fluororesin, and brought into contact with the surface of a honeycomb rotor, thereby sealing the respective zones. The outer peripheral seal 9 and the inner peripheral seal 8 are formed by superposing a plurality of heat resisting sheets with a plurality of slits 12, 13 at each one end thereof so that the slits do not coincide with each other, and the outer peripheral seal 9 is bent to be pushed out to the inside of the desorption zone 4.

Description

technical field [0001] The present invention relates to a technology for adsorbing and removing gases such as organic solvent vapor from exhaust gas of factories and the like using a honeycomb rotor, and relates to a gas adsorption and concentration device capable of regeneration at high temperatures. Background technique [0002] Many devices have been proposed for adsorbing and removing organic solvent vapor from exhaust gas from factories or the like using honeycomb rotors loaded with adsorbents such as zeolite. As far as such a device is concerned, in practical applications, it is enough to adsorb organic solvent vapors such as toluene or xylene with a boiling point below 100 degrees Celsius on the honeycomb rotor, and use heat to desorb. For example, the adsorption rate can exceed 98%, and the concentration rate can reach 20 times, and it can fully demonstrate its strength as an environmental countermeasure device, and it is also spreading. [0003] In such an organic ...

Problems solved by technology

Therefore, there is a problem that if the fluororesin plate is pressed against the honeycomb runner by the elastic force of the rubber plate as in the structure disclosed in Patent Document 1, the elasticity of the rubber is not sufficient at a temperature close to 250 degrees Celsius, so The sealing effect cannot be fully exerted
