Abstract

The invention discloses a heat storage combustion device with an annular rotating valve. The device comprises a combustion chamber, a heat storage body, an annular gas separation plate and the annularrotating valve; the annular rotating valve is characterized by comprising an annular intake box, an annular scavenging box, an exhaust box, a rotating valve element and a transmission device; the annular scavenging box is mounted between the annular intake box and the exhaust box; a purging intake ring is mounted at the lower part of a purging sleeve of the purging intake ring of the rotating valve element; the purging intake ring is mounted in the annular scavenging box; a sealing piece is mounted between the purging intake ring and the annular scavenging box; the rotating valve element is rotated to purge cleaning gas into the purging intake ring of the purging intake ring from the annular scavenging box; and the annular intake box and the exhaust box are separated by purging cleaning gas with relatively higher pressure in the annular scavenging box, so that leakage of organic waste gas to be treated into the exhaust box is prevented to the greatest extent.

Description

technical field [0001] The invention relates to a regenerative combustion device with a ring-type 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 finally dis...
