Process Description:

Ø Waste gasesUnder the operation of the RTO fan, the air first passes through the spray tower and electrostatic deoiling equipment for pretreatment, then through primary filtration before being sent into the internal oxidation reaction of the RTO unit. The treated exhaust gas is emitted high into the atmosphere through the chimney. The air volume from the front pipeline is automatically adjusted by the variable frequency drive, ensuring that the air volume supplied by the RTO fan matches the exhaust gas volume.

Ø Emergency exhaust ducts are set up in the RTO system. In case of a failure in the RTO system, where it cannot continue to operate, temporary emergency exhaust of the waste gas is required to avoid disrupting the workshop production. The front-end exhaust fan must be capable of directing the waste gas into the chimney for排放.

Ø Electrical control cabinet suppliedThe RTO system supplies matched power and monitors and controls the normal operation of the system; the owner must connect the power supply to the electrical cabinet.

Ø The owner's compressed air provided in the compressed air system is purified through the action of the air storage tank and three-way valve, removing water, oil, and dust from the gas to supply clean air to pneumatic actuators and burners; the owner must provideRTO equipment with reserved interfaces within 1-meter range.

Ø Natural gas is the fuel for burners, and the gas pipeline can meet the high consumption needs of burners. The natural 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 gas treatmentThe 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 oxidized high-temperature gas is stored in the ceramic heat storage body."Store" it to preheat incoming organic waste gases, thereby saving fuel and reducing operating costs.

2、WorkProcess

One cycle：

Heat storage chamber1： Organic waste gases are drawn into the heat storage chamber by a blower.1Ceramic Heat Storage Body"Stored" heat from the previous cycle (at high temperatures), at this point, the ceramic heat storage medium releases heat, causing its temperature to drop, while the organic waste gases absorb the heat, resulting in an increase in their temperature. The waste gases then pass 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, facilitating the oxidation and decomposition of organic matter into harmless substances.CO₂AndH₂O, if the exhaust temperature does not reach the oxidation temperature, it will be directly heated by the burner to compensate to the oxidation temperature; since the exhaust gas is already in the heat storage chamber1Preheat, 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 from the oxidation decomposition of organic matter can sustain the self-ignition), and the high-temperature gas after oxidation passes through a ceramic heat storage unit.2Discharge.

Heat Storage Room2： Oxidized high-temperature gases enter the regenerative chamber2(At this point, the ceramic is in a lower temperature state), the high-temperature gas releases a large amount of heat to the heat storage ceramic2Gas cooling, ceramic heat storage chamber2After absorbing a large amount of heat and increasing in temperature for storage (used for preheating organic waste gases in the next cycle), the gas is discharged into the atmosphere through the chimney, with the exhaust temperature being higher than the intake temperature.Difference less than6Approximately 0°C。

Thermal Storage Chamber3Ceramic 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, which is blown back to the main fan inlet and enters the ceramic heat storage chamber with the organic waste gas using a small amount of high-temperature gas from the oxidation chamber.3。

Two-way circulation: Exhaust gas from the heat storage chamber2Enter, then from the heat storage room3Discharge, heat storage chamber1Perform reverse air cleaning.

Three Cycles: Exhaust gas from the heat storage chamber3Enter, then proceed to the heat storage room1Discharge, heat storage room2Perform reverse air cleaning.

The cycle continues, replacements and exchanges occur.。
