Tail gas switching peak value purification device with heat accumulating type incinerator

Abstract

The invention relates to a tail gas switching peak value purification device with a heat accumulating type incinerator, which comprises the heat accumulating type incinerator and a poppet valve, wherein the inside of the heat accumulating type incinerator is partitioned into a first heat accumulating chamber, a second heat accumulating chamber and a combustion chamber at least, the outside of the heat accumulating type incinerator is connected with a waste gas inlet pipe and an exhaust pipe, and both the inlet pipe and the exhaust pipe are provided with flow control valves; the poppet valve is partitioned into a gas inlet layer connected with the exhaust pipe, a purified gas outlet layer connected with an exhaust chimney and an unpurified gas outlet layer connected with a buffering pipe body, and the lifting of an internal disc is controlled by a drive part to switch airflow to flow out from the purified gas outlet layer or the unpurified gas outlet layer; the other end of the buffering pipe body is connected with the exhaust chimney; the total volume of the buffering pipe body and the unpurified gas outlet layer cannot be smaller than the volume of unpurified gas retained in the heat accumulating chambers and the flow control valve. The tail gas switching peak value purification device has the efficacies of small pressure variation, stable system, less odor, simple structure and space saving.

Description

Technical field [0001] The invention relates to a regenerative incinerator tail gas switching peak purification device, in particular to a lift valve that controls the flow direction of the air flow after incineration in the incinerator, and is directly connected to the exhaust chimney and the outer valve of the incinerator. The air outlet layer is connected to the design of the buffer tube body. Background technique [0002] Organic solvents widely used in life and production are easily volatile into gases at room temperature, so they are also called Volatile Organic Compounds (VOCs). Most VOCs are toxic to the human body and must be treated. However, the incineration method is one of the VOCs waste gas treatment methods. Under appropriate conditions, the VOCs removal rate can reach 90-99%. The products after combustion are usually water, carbon dioxide, nitrogen oxides, sulfur oxides, etc. A method that can effectively treat the VOCs and odor contained in the exhaust gas; but ...
