Process Description:
Ø Waste gasUnder the action of the RTO fan, the air first passes through a spray tower and an electrostatic degreasing unit for pretreatment, then through a primary filter, and is sent into the internal oxidation reaction of the RTO unit. After treatment, the exhaust gas is emitted high into the air through a chimney; the air volume supplied by the RTO fan is automatically adjusted to match the exhaust gas volume based on the air volume supplied by the front-end pipeline through a variable-frequency inverter.
Ø Emergency exhaust piping is set up in the RTO system. In the event of a system failure, where the RTO system is unable to continue operation, temporary emergency exhaust of the waste gas is necessary to avoid disrupting the workshop production. The front-end waste gas fan must be capable of directing the waste gas into the chimney for discharge.
Ø Electrical control cabinet providedThe RTO system provides matched power supply, monitors, and controls the normal operation of the system; the owner must connect the power supply to the electrical cabinet.
Ø Owner-supplied compressed air in the compressed air system is processed through a storage tank and a three-way valve to remove water, oil, and dust from the gas, providing clean gas for pneumatic actuators and burners; the owner must provideRTO equipment with pre-installed interfaces within 1m 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, ensuring 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 high-temperature gases after oxidation is stored in a ceramic regenerator.Store to preheat incoming organic waste gases, thereby saving fuel and reducing operating costs.
2、WorkProcess
One cycle：
Storage chamber1： Organic waste gases are drawn into the heat storage chamber by the induced draft fan.1Ceramic Heat Storage Units"Heat stored from the previous cycle (at a high temperature state) is released by the ceramic heat storage unit, causing a drop in temperature, while the organic waste gas absorbs the heat, leading to an increase in temperature as the waste gas passes through the heat storage chamber."1After heat exchange, it enters the oxidation chamber at a higher temperature.
Oxygen Chemical Room: Ceramic heat storage chamber1Heated organic waste gas enters the oxidation chamber at a high temperature for reaction, causing the organic matter to oxidize and decompose into harmless substances.CO2AndH2O, if the exhaust gas temperature does not reach the oxidation temperature, the burner will directly heat 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), and the high-temperature gas after oxidation passes through a ceramic heat storage unit.2Discharge.
Storage chamber2： Oxidized high-temperature gases enter the heat storage chamber2(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, while the ceramic heat storage chamber2After absorbing a large amount of heat and升温for storage (used for preheating organic waste gas in the next cycle), the gas is discharged into the atmosphere through the chimney after being acted upon by the fan, with the exhaust temperature being higher than the intake temperature.Difference less than6Approximately 0°C。
Heat Storage Room3Ceramic Heat Retention Chamber3In sweeping mode, upon valve switching at the end of the previous cycle, valve and ceramic heat storage3There is a small amount of exhaust gas between the bottom sections, which is blown back to the main fan inlet along with the organic waste gas by a small amount of high-temperature gas from the oxidation chamber.3。
Recirculation: Waste gas from the heat storage chamber2Enter, then proceed to the heat storage room3Discharge, Heat Retention Chamber1Perform reverse blow cleaning.
Three Cycles: Exhaust gas from the heat storage chamber3Enter, then proceed to the heat storage room1Discharge, Heat Retention Chamber2Perform reverse air blowing cleaning.
The cycle continues, replacements are exchanged.。
