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. Before organic waste gas enters the ceramic heat accumulator, a large amount of dust is contained and needs to be filtered, so that the heat accumulation ceramic is prevented from scaling; the traditional filter screen has low filtering efficiency and is easy to block, thereby causing unsmooth circulation of waste gas and being not suitable for filtering organic waste gas with large air volume. An effective RTO waste gas filtering device is urgently needed at present to prevent the heat storage ceramic from scaling.
