INSTALLATION FOR ADSORPTION GAS DRYING Russian patent published in 1999 - IPC

FIELD: adsorption-type installations with capillary condensation adsorbent, in which adsorbent recovery is accomplished by heating of adsorber with blowing it through by dry air. SUBSTANCE: installation has a compressor, two adsorbers, using equipment air duct connecting them, return air duct connecting the adsorbers on the inlet side, inlet air duct, compressor suction and pressure air ducts, four selector valves, check valve, throttle valve, compressed-air receiver and an electric contact pressure gauge connected to it. The consuming equipment air duct has two check valves, the adsorbers are connected in parallel with it by recovery air duct with an electropneumatic valve and throttle valve installed on it; a vacuum receiver is installed between the return and suction air ducts of the compressor, and an electric contact vacuum gauge is installed on the compressor suction air duct connecting it to the atmosphere. EFFECT: enhanced efficiency due to enhanced degree of adsorbent recovery by vacuum treatment. 1 dwg
