[0027] It should be noted that in the existing RTO waste gas treatment technology, some residues will be produced after the waste gas is burned in the combustion chamber, which may adhere to the heat accumulator. When the back flushing gas needs to be introduced, the system will close the waste gas introduction valve and open the back flushing gas introduction valve at the same time, so that the purified gas can smoothly enter the heat storage chamber for purging, keeping the heat accumulator clean, thereby ensuring the continuous and efficient operation of the RTO equipment.
