Abstract

The invention discloses a rotary self-cleaning type fluted disc switching valve. The rotary self-cleaning type fluted disc switching valve comprises a fluted disc, a valve plate, a valve seat and a rotating device. The valve seat and the valve plate are eccentrically installed, a gear of the rotating device drives the fluted disc to rotate, the valve plate and the valve seat are in contact friction to erase away dirt, and automatic cleaning work is achieved under the working condition without a halt; contact surfaces of the valve plate and the valve seat are continuously changed, the problem that sealing is affected by work fatigue deformation of a valve plate of a switching valve is completely solved, and the waste gas purification quality and efficiency of a regenerative combustion device are greatly improved.

Description

technical field [0001] The invention relates to a rotary self-cleaning gear plate switching valve of a regenerative combustion device, in particular to the technical field of a regenerative RTO combustion device for waste gas treatment. Background technique [0002] The current regenerative combustion device RTO heats the organic waste gas discharged from production through heat storage ceramics, and the temperature rises rapidly. Under the action of gas combustion and heating in the furnace, the temperature reaches 680-1050°C, and the VOCs in the organic waste gas are here It is directly decomposed into carbon dioxide and water vapor at high temperature to form odorless high-temperature flue gas, and then flows through the low-temperature regenerative ceramics. The temperature of the exhaust gas and high-temperature flue gas drops significantly, and then heat exchange occurs with other media through the heat recovery system, the temperature of the flue gas is further reduce...
