发明名称 MULTIPASS VALVE AND APPARATUS WITH MULTIPASS VALVE FOR REGENERATIVE THERMAL OXIDATION
摘要 FIELD: the invention refers to apparatus of regenerative thermal oxidation with multi pass valves. ^ SUBSTANCE: the apparatus for regenerative thermal oxidation for gas processing has a combustion zone, the first heat exchanging layer keeping heat exchanging surroundings and connecting with the combustion zone; the second heat exchanging layer keeping heat exchanging surroundings and connecting with the combustion zone; a valve for alternate direction of the gas flow between the first and the second heat exchanging layers. At that the valve has the first valve passage and the second valve passage separated from the first valve passage; a flow distributor having an admission passage communicates with the help of fluid medium with the admission opening of the surroundings and an exhaust passage communicates with the help of fluid medium with exhaust opening of fluid surroundings. At that the distributor is fulfilled with possibilities of its the first and the second valve passages between the first position in which the first valve passage communicates with the help of liquid with the admission passage and the second valve passage communicates with the help of liquid surroundings with exhaust passage and the second position in which the indicated the first valve passage communicates with the help of the fluid surrounding with exhaust passage and the second passage of the entry of the valve with the help of liquid surroundings communicates with the admission passage. At that the distributor of flow has a blocking surface which blocks the flow through the first part of the first valve passage and through the second part of the second valve passage when the distributor of the flow is between the first and the second positions and is fulfilled with possibility of its turning to 180o between the first and the second positions. At that valve passage is divided as the first so is the second at least into two chambers and the first and the second parts of the valve passages are congruous. ^ EFFECT: simplifies the construction, provides comfort of controlling and exploitation and deep removal of volatile organic combinations. ^ 22 cl, 12 dwg
