Process Description:
Ø Waste gasUnder the action of the RTO fan, the gas is first pre-treated through a spray tower and an electrostatic oil removal device, then goes through a primary filter before being sent into the internal oxidation reaction of the RTO unit. The treated exhaust gas is then released high into the atmosphere through a chimney. The air volume of the RTO fan is automatically adjusted by a variable frequency drive to match the exhaust gas volume based on the air volume sent through the front pipeline.
Ø Emergency exhaust pipeline is set up in the RTO system. In case of a fault 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 into the chimney for排放.
Ø Electrical control cabinet providedThe RTO system provides matching power supply, monitors, and controls the normal operation of the system; 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-in-one assembly to remove water, oil, and dust from the gas, supplying clean air to pneumatic actuators and combustion engines; the owner must provideRTO equipment with reserved interfaces within 1m range.
Ø Natural gas serves as the fuel for burners, with gas pipelines capable of meeting the high consumption needs of burners. The gas supply must be connected to the burner valve assembly by the owner. The burner valve assembly is equipped with a gas leak detection device, ensuring 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 oxidized high-temperature gas is stored in the ceramic regenerator.Store it to preheat incoming organic waste gases, thereby saving fuel and reducing operational costs.
2、WorkProcess
One cycle：
Storage chamber1： Organic waste gases are drawn into the heat storage chamber by a blower.1Ceramic Heat Storage Body"Heat stored from the previous cycle (at high temperatures) is released by the ceramic heat storage unit, causing a drop in temperature, while the organic waste gases absorb the heat, leading to an increase in their temperature as they pass through the heat storage chamber."1The heat-exchanged material enters the oxidation chamber at a higher temperature.
Oxygen Please provide the Chinese content to be translated. Room: Ceramics 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 for the oxidation temperature, as 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 by the oxidation decomposition of organic matter can sustain self-ignition), and the high-temperature gas after oxidation passes through a ceramic heat storage body.2Discharge.
Thermal storage room2： 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 regenerative ceramics2Gas cooling, while the ceramic heat storage chamber2After absorbing a large amount of heat and increasing in temperature for storage (used to preheat organic waste gas in the next cycle), the gas is exhausted through the chimney into the atmosphere by the fan, with the exhaust gas temperature higher than the intake temperature.Difference less than6Approximately 0°C。
Storage chamber3Ceramic Heat Retention Chamber3In sweep mode, upon valve switching at the end of the previous cycle, the valve and ceramic heat storage unit3A small amount of exhaust gas exists between the bottom of the equipment, which is blown back to the main fan inlet in a small amount of high-temperature gas in the oxidation chamber, and enters the ceramic heat storage chamber together with the organic exhaust gas.3。
Secondary circulation: Exhaust gas from the heat storage chamber2Enter, then into the heat storage chamber3Discharge, heat storage room1Perform reverse-air cleaning.
Three Cycles: Waste gas from the heat storage chamber3Enter, then proceed to the heat storage room1Discharge, Heat Accumulation Chamber2Perform reverse air cleaning.
The cycle continues, replacements exchanged.。
