Description

Technical Field

[0001] This utility model relates to the technical field of RTO regenerative thermal oxidation devices, specifically a multi-channel switching RTO regenerative thermal oxidation device. Background Technology

[0002] Regenerative Thermal Oxidizer (RTO) is a highly efficient organic waste gas treatment device. It uses a ceramic heat storage and release element to heat organic waste gas to a high temperature for oxidation and decomposition. It features energy saving, high purification efficiency, and wide applicability.

[0003] Common RTO (Regenerative Thermal Oxidizer) devices typically provide heat through a burner, allowing the organic waste gas to reach the temperature required for oxidation and decomposition in the combustion chamber. The combustion chamber is used to oxidize the organic waste gas, and the heat is stored in the regenerative chamber.

[0004] However, after the exhaust gas is injected into the regenerative oxidation device, the particulate matter in the exhaust gas may clog the heat storage body, valves, pipes and other components, affecting the normal operation of the equipment. Furthermore, after a period of operation, the ceramic heat storage body may develop cracks, fissures and pulverization due to the accumulation of particulate matter, making the equipment prone to failure. Utility Model Content

The bolts can stably install the mounting plate onto the surface of the activated carbon adsorption box, and also facilitate the disassembly of the mounting plate to replace the activated carbon in the activated carbon adsorption box.

[0013] Preferably, limiting plates are installed inside the filter box at positions corresponding to the metal wire mesh filter plate and the activated carbon adsorption box. A receiving frame is provided at the bottom of the metal wire mesh filter plate and the activated carbon adsorption box. The limiting plates are located above the metal wire mesh filter plate and the activated carbon adsorption box. The receiving frame is installed on the inner wall of the filter box.

[0017] Beneficial effects
