Abstract

The invention provides a heat-storage combustion device with a double-valve-plate rotary valve. The heat-storage combustion device with the double-valve-plate rotary valve comprises a combustion chamber, a heat-storage box and the double-valve-plate rotary valve, wherein the double-valve-plate rotary valve comprises an annular gas distributing plate, a gas feeding box, a gas discharging box, a blowing box, an upper valve plate and a lower valve plate; the upper valve plate is mounted on the upper part of the annular gas distributing plate; the lower valve plate is mounted on the lower part ofthe annular gas distributing plate; an upper fan-shaped gas flow channel is formed in the upper valve plate; a lower fan-shaped air flow channel is formed in the lower valve plate; a scavenge box is mounted on the lower valve plate; the upper valve plate is connected with the lower valve plate through a synchronous rotating shaft; the upper valve plate and the lower valve plate rotate synchronously; organic waste gas to-be-treated enters the heat-storage box and the combustion box through the upper fan-shaped gas flow channel; the treated waste gas in the heat-storage box enters the gas discharging box through the lower fan-shaped gas flow channel and then is discharged; and clean gas in the scavenge box enters from a lower blowing hole of the lower valve plate to clean residual waste gasin the annular gas distributing plate and the heat-storage box.

Description

technical field [0001] The invention relates to a regenerative combustion device with a double-valve plate rotary valve, and relates to the technical field of regenerative combustion devices (RTO). Background technique [0002] The current regenerative combustion device (RTO) heats the organic waste gas discharged from the production through the 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 At this high temperature, it is directly decomposed into carbon dioxide and water vapor to form odorless high-temperature flue gas, which then flows through the low-temperature regenerative ceramics. The organic waste gas is decomposed, and the temperature of the high-temperature flue gas itself is greatly reduced. After heat exchange with other media through the heat recovery system, the temperature of the flue gas is further reduced, and fi...
