Four-way valve device applied to organic waste gas treatment

Abstract

The invention discloses a four-way valve device applied to organic waste gas treatment. The four-way valve device comprises a first regenerative chamber, a second regenerative chamber, a main exhaust pipe and a main air inlet pipe; a valve barrel body is arranged beside the first regenerative chamber and the second regenerative chamber; a valve rod is arranged in an air inlet chamber of the valve barrel body; a first valve plate positioned above a first regenerative hole, a second valve plate positioned below the first regenerative hole, a third valve plate positioned above a second regenerative hole, and a fourth valve plate positioned below the second regenerative hole are sequentially mounted on the valve rod. According to the four-way valve device, the single-rod valve body is arranged between an air inlet, an exhaust port and the two regenerative chambers, so that the structure of the valve rod is optimized, and the direction changing of the airflow in a pipeline is realized; the four-way valve device can be applied to double-bed regenerative type combustion devices and regenerative type catalytic combustion devices for organic waste gas treatment, and four valves of an airflow control system in original equipment are replaced, so that the structure is optimized, the operation is simplified, and the mounting and the layout of pipelines are simplified.

Description

Technical field [0001] The invention relates to an air flow control device, in particular to a four-way valve device applied to the treatment of organic waste gas. Background technique [0002] Regenerative combustion (RTO) and regenerative catalytic combustion (RCO) devices have been increasingly popularized in organic waste gas treatment due to their heat recovery rate of up to 95%. The original double-bed type regenerative combustion (RTO) and During the operation of the double-bed type regenerative catalytic combustion (RCO), the gas flow direction is reversed intermittently, so the gas alternately passes through the ceramic regenerator bed, is heated when it enters the reactor, and is cooled when it exits the reactor . That is to say, the two regenerators must go through the process of heat absorption and heat dissipation in turn, so both regenerators need an intake pipe and an exhaust pipe. The control and switching of this airflow must be achieved by setting up four valv...

AI Technical Summary

Problems solved by technology

The control switching of this air flow must be realized by setting four valves (corresponding to the inlet pipe and exhaust pipe of the two regenerators respectively), the operation is complicated, and the distribution of the pipes is also greatly restricted. Therefore, in terms of structural optimization of RTO and RCO devices needs improvement
