Description

Technical Field

[0001] The utility model relates to the technical field of RTO waste gas separation, in particular to an RTO waste gas separation and collection device. Background Art

[0002] RTO stands for Regenerative Thermal Oxidizer. Its principle is to oxidize organic matter (VOCs) in exhaust gas into corresponding carbon dioxide and water at high temperature, thereby purifying the exhaust gas and recovering the heat released when the exhaust gas is decomposed. The three-chamber RTO exhaust gas decomposition efficiency reaches more than 99%, and the heat recovery efficiency reaches more than 95%.

[0003] In the Chinese utility model patent "CN219913091U a RTO waste gas treatment equipment", the waste gas is introduced into the RTO waste gas incinerator from the waste gas inlet pipe through the first fan, and first preheated by the heat storage chamber. Each heat storage chamber undergoes heat storage, heat release and cleaning through the back-blowing cleaning pipe in turn, which is repeated and works continuously. After the heat storage chamber releases heat, an appropriate amount of clean air should be introduced immediately to clean the heat storage chamber. Only after the cleaning is completed can the heat storage procedure be entered, and then the combustion chamber is entered, and the combustion chamber is heated by the igniter, and the waste gas in the waste gas is removed at high temperature. Organic matter (VOCs) is oxidized into corresponding carbon dioxide and water. The generated carbon dioxide and unpurified waste gas will enter the secondary treatment box through the exhaust pipe. The secondary treatment box is equipped with an activated carbon filter to adsorb the odor in the waste gas that has not been completely purified by high-temperature combustion and can adsorb and filter the waste gas. However, the activated carbon filter is installed on the inner side of the secondary treatment box, which is not convenient for cleaning or replacing the activated carbon filter. The effect of the activated carbon filter will decrease with long-term use. Therefore, an RTO waste gas separation and collection device is proposed to solve the above problems.
