Abstract

The invention relates to an air tight construction of changeover valve, in particular to air tight construction for changeover valve of rotation heat accumulating type incinerator. The changeover valve comprises a stator and a rotor, the air tight construction is arranged at the periphery of the rotor, so that the gap between the stator and rotor is air tight, and the air tight construction comprises a first sealing device and a second sealing device, wherein the first sealing device is provided with a permanent seat, a connecting part, first sealing material, a conductive and against construction member, a locking and fixing construction member and a spring, and the second sealing device is provided with a fastening construction member and second sealing material. By virtue of the two sealing devices or the first sealing device, complete air tight construction of the changeover valve is provided, and the air tight construction has heat resistance, abrasion resistance and chemical stability.

Description

technical field [0001] The invention relates to an airtight structure of a rotary valve, in particular to an airtight structure applied to a rotary valve of a rotary regenerative incinerator. Background technique [0002] In recent years, more and more attention has been paid to environmental protection issues at home and abroad, and the emission standards for industrial waste gas have become increasingly strict. Volatile organic compounds (VOCs) have become one of the current air pollution prevention and control priorities. [0003] The incineration method is a kind of treatment of VOCs waste gas. Under proper incineration conditions, the removal rate of VOCs can reach more than 99%. The combustion products vary according to the feed gas. The usual products are water, carbon dioxide, nitrogen oxides, and sulfur. oxides, etc. The incineration method can generally effectively improve the VOCs and odor problems contained in the exhaust gas, however, it consumes a lot of fuel....
