Process Description:

Ø Waste gasUnder the action of the RTO fan, the waste gas first passes through a spray tower and an electrostatic oil-removing device for pretreatment, then undergoes primary filtration before being sent into the internal oxidation reaction of the RTO unit. The treated exhaust gas is then released into the atmosphere through a chimney. The air volume supplied by the RTO fan is automatically adjusted by a variable-frequency drive to match the exhaust gas volume according to the air volume supplied by the front-end pipeline.

Ø Emergency exhaust pipeline is set up in the RTO system. In case of a failure in the RTO system where it cannot continue operation, temporary emergency exhaust of the waste gas is required to avoid affecting the workshop production. The front-end waste gas fan must be capable of delivering the waste gas to the chimney for discharge.

Ø Electrical control cabinet providedThe RTO system provides matched power supply, monitoring, and control of the system's normal operation; the owner must connect the power supply to the electrical cabinet.

Ø The compressed air provided by the owner in the compressed air system passes through a storage tank and a three-way valve, removing water, oil, and dust from the gas, providing clean air for pneumatic actuators and burners; the owner must provideRTO equipment with reserved interfaces within a 1-meter range.

Ø Natural gas is the fuel used in burners. The natural gas pipeline can meet the high consumption needs of the burners. The gas must be connected to the burner valve group interface by the owner. The burner valve group is equipped with a gas leak detection device to ensure safe operation.

1、RTOPrincipleDescription

Organic waste gases throughThe RTO oxidation chamber's high-temperature zone oxidizes and decomposes VOC components in the waste gas into harmless CO.₂AndH₂O, Reaction Equation: The heat from the high-temperature gases after oxidation is stored in the ceramic regenerator.Store it to preheat incoming organic waste gases, thereby saving fuel and reducing operating costs.

2、WorkProcess

One cycle：

Thermal Storage Room1： Organic waste gas is drawn into the heat storage chamber by a blower.1Ceramic Heat Storage Units"Heat stored from the previous cycle, now at a high temperature), at this point, the ceramic heat storage body releases heat, resulting in a temperature drop, while the organic waste gas absorbs heat, causing an increase in temperature. The waste gas then passes through the heat storage chamber."1After heat exchange, enter the oxidation chamber at a higher temperature.

Oxygen Chemical Room: Passed through the ceramic heat storage room1The heat-exchanged organic waste gas enters the oxidation chamber at a high temperature, causing the organic matter to oxidize and decompose into harmless substances.CO₂AndH₂O, if the exhaust gas temperature does not reach the oxidation temperature, it is directly heated by the burner to compensate to the oxidation temperature; since the exhaust gas is already in the heat storage chamber,1Preheat, entering the oxidation chamber only requires slight heating to reach the oxidation temperature (if the exhaust gas concentration is high enough, heating with natural gas during oxidation may not be necessary; the heat released by the oxidation decomposition of organic matter can sustain the self-ignition). The high-temperature gases after oxidation pass through a ceramic heat storage unit.2Discharge.

Storage chamber2： Oxidized high-temperature gases enter the regenerative chamber.2(At this point, the ceramics are in a lower temperature state), the high-temperature gases release a large amount of heat to the heat storage ceramics2Gas cooling, ceramic heat storage chamber2After absorbing a large amount of heat and increasing in temperature for storage (used for preheating organic waste gas in the next cycle), the gas is exhausted through the chimney into the atmosphere under the action of the fan, with the exhaust temperature higher than the intake temperature.Difference less than6Approximately 0°C。

Thermal Storage Room3Ceramic Heat Storage Chamber3In sweeping mode, upon valve switching at the end of the previous cycle, the valve and ceramic heat storage body3There is a small amount of waste gas between the bottom sections, which is blown back to the main fan inlet along with the organic waste gas using a small amount of high-temperature gas in the oxidation chamber.3。

Secondary circulation: Waste gas from the heat storage chamber2Enter, from the heat storage chamber3Discharge, heat storage room1Perform reverse air blowing cleaning.

Three Cycles: Exhaust gas from the heat storage chamber3Enter, then proceed to the heat storage room1Discharge, Heat Retention Chamber2Perform reverse air cleaning.

The cycle continues, replacements and exchanges occur.。
