Description

Spherical switching valve of RTO device

Technical Field

The invention discloses a spherical switching valve of an RTO device, and relates to the technical field of Regenerative Thermal Oxidizer (RTO).

Background

The current Regenerative Thermal Oxidizer (RTO) heats organic waste gas discharged in production through regenerative ceramic, the temperature is rapidly increased, under the combustion heating effect of gas in a hearth, the temperature reaches 680-1050 ℃, VOCs in the organic waste gas are directly decomposed into carbon dioxide and water vapor at high temperature to form tasteless high-temperature flue gas, then the flue gas flows through the regenerative ceramic with low temperature, a large amount of heat energy is transferred to a heat accumulator from the flue gas to heat organic waste gas to be decomposed of next circulation, the self temperature of the high-temperature flue gas is greatly reduced, heat exchange is carried out through a heat recovery system and other media, the temperature of the flue gas is further reduced, and finally the flue gas is discharged to outdoor atmosphere. The switching valve of the existing RTO three-chamber waste gas treatment device has the defects of sealing failure and the like; the market urgently needs a simple and effective spherical switching valve of an RTO device to improve the sealing performance of the switching valve.
