Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, specifically to an explosion-proof RTO waste gas treatment device. Background Technology
[0002] RTO, or Regenerative Thermal Oxidizer, is an industrial waste gas treatment device. Its principle is to oxidize combustible waste gas into corresponding oxides and water at high temperatures, thereby purifying the waste gas and recovering the heat released during decomposition. Its waste gas decomposition efficiency is higher than that of traditional direct-fired oxidizers. An RTO typically includes a regenerator chamber and a combustion chamber. The regenerator chamber is used to recover the heat generated during pyrolysis and to allow the gas to enter the oxidizer.
[0003] Existing RTO exhaust gas treatment devices are inconvenient to disassemble the primary filter plate, making it impossible to clean it regularly or replace it when damaged. They also cannot easily stop supplying gas to the RTO exhaust gas treatment device after the pressure reaches a certain threshold, leading to excessive gas intake and pressure, which can easily cause an explosion. Furthermore, they cannot easily utilize the hot gas from the combustion chamber to preheat the exhaust gas in the heat storage chamber, resulting in insufficient energy efficiency and environmental friendliness, and high energy costs. The inconvenience in controlling the intake airflow rate leads to poor flexibility and hinders automatic exhaust gas introduction for treatment, necessitating the use of additional gas guiding equipment and increasing exhaust gas treatment costs. Therefore, this utility model provides an explosion-proof RTO exhaust gas treatment device. Utility Model Content

The rotating fan then guides the hot air from the combustion chamber through the heat pipe into the heat storage chamber, facilitating the preheating of the exhaust gas in the heat storage chamber. A flow control box, slot two, flow control plates, handle two, and flow control holes are also integrated. When in use, the operator holds handle two and pushes or pulls it, causing the two flow control plates to extend and retract within the flow control box.

Finally, an intake duct one, intake duct two, a micro motor two, a transmission rod two, and a guide fan are also integrated. During operation, the micro motor, connected to a power source, drives the transmission rod two and the guide fan to rotate. The rotating fan then guides the exhaust gas through the intake duct one and intake duct two into the heat storage chamber, thus automatically introducing and treating the exhaust gas.
