Description
Technical Field
The utility model discloses an efficient mixing device for RTO waste gas, 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 existing RTO waste gas treatment device has the problems that multi-pipeline organic waste gas is input, the temperature, the pressure and the solvent of the organic waste gas are different and need to be fully mixed; the market urgently needs a simple and effective RTO waste gas high-efficient mixing arrangement to improve the mixing performance of waste gas.
