CPI - Model TRITON III Series - Regenerative Thermal Oxidizer (RTO)
The TRITON-Series Regenerative Thermal Oxidizer process begins with the touch of a button, which activates the system’s PLC-based Temperature Safety System (TSS). The TSS control system automatically retrieves media temperatures, selects the hottest bed for damper positioning, opens the fresh air purge/idle damper, energizes the booster fan, purges the system with fresh air, ignites the burner, cycles the valves, and gradually brings the system up to the correct operating temperature. The TSS also monitors the temperature in the regenerators, combustion chamber in three places, and in the valve assembly’s inlet and outlet. This helps safeguard the system from extreme temperature fluctuations that cause thermal stress and overall system fatigue.
As soon as the required operating temperature is reached, the TSS enables the process lines to feed into the oxidizer, or holds the system in idle mode until production is ready. When production is ready the fresh air purge damper closes and one or more of the diverting dampers open to draw the volatile organic compounds (VOC’s) off of the process lines.
A booster fan draws one or more VOC-laden exhaust from your process lines into the system. From there, VOC’s are directed into one of the systems regenerators (an internally insulated vessel containing ceramic media). The contaminated gases are passed through the first regenerator where energy is transferred from the ceramic media to the gas in order to elevate the temperature. This elevated temperature approaches the ignition level for most solvents and then is directed from the ceramic bed into the combustion chamber. As the stream exits the ceramic bed and travels through the internally lined combustion chamber minimal heat is added to ensure a proper oxidation temperature and a designed dwell time is maintained for the ultimate destruction of the streams VOC’s. The oxidized gases are then directed to the second regenerator to absorb the heat energy. As the ceramic media loads with sufficient heat, the Posi-Seal Valves switch, and the gases are reversed through the system where the second regenerator bed continues the energy transfer and oxidation cycle before being released to the atmosphere.
While the first and second regenerators are exchanging energy, the third regenerator is being purged with clean air. This purging of valves and regenerator prevent un-treated VOC’s from ever reaching the atmosphere and is the basis for TRITON III-Series Regenerative Thermal Oxidizer’s ability to reach +99.9% removal efficiency. The purge air is internally recirculated back through the combustion chamber and over the exhausting regenerator tower before being release to atmosphere, or to auxiliary heating systems such as; secondary air to air recovery, air to water recovery, air to oil recovery, or directly back to the process in a closed loop direct recirculation process.
Modular Regenerator Technology
TRITON RTO’s are custom designed for the highest reliability with the lowest overall costs.The complete system is designed with a modular approach for the most cost-effective solution. The TRITON is supplied as a thee-tower (or multi-tower) regenerator system fitted to our Even-Flo Valve Manifold. This modular approach satisfies your needs for a competitive installation cost and insures that the Posi-Seal valves are properly installed and aligned prior to leaving the factory.
Cold Face Support
Complementing the regenerator design is our unique cold face support system. While other systems merely rely on a perforated plate to support the ceramic media, TRITON systems have utilized a superior supporting grid that allows the lowest pressure drops and highest structural integrity. Based on the application needs, the TRITON-Series RTO can be supplied with stainless steel metallurgy to resist chemical attack or added thermal stresses,
Thermal Heat Transfer Matrix
Each TRITON system is designed around the specific ceramic heat transfer matrix recommended for the application. TRITON-Series systems can be designed using a layered structural ceramic matrix or a mix of structured and random media, depending on your application’s requirements.The thermal heat transfer matrix is the key to a well designed and efficient system.With thermal rate efficiencies (TRE) ranging from 85% to 97% you can be assured that even the lowest VOC concentrations can be economically destroyed.
Posi-Seal valves are designed to take advantage of a vertical axis that allows for soft seating action with self-centering guidance. The innovative feature about all Posi-Seal valves is the air tight machined seal that eliminates valve bypass and maintenance intensive gaskets. The Posi-Seal valve will be pneumatically operated and will cycle open or closed based on the program logic called for in your application.
Posi-Seal Shaft Cooling
TRITON Systems incorporate shaft and bearing cooling systems.This simple, yet often overlooked feature provides a cool supply of air in the bearing tube and on the bearings.This prevents leakage of the higher pressure air on the inside of the oxidizer from escaping to atmosphere and helps cool the shaft and bearings for long life.
EvenFlo Valve Manifolds
All TRITON systems are designed with our innovative “EvenFlo” Valve Manifold design. EvenFlo Manifolds are duct-under design that precisely locates the “Posi-Seal” valves in relationship to a specific distance away from the regenerator. TRITON system take advantage of the duct-under orientation in order to minimize the flushing and purge volume and maximizing flushing efficiency. The “EvenFlo” Manifolds are factory assembled and include factory set and adjusted valve strokes.
Internal Insulation Systems
The TRITON-Series RTO is internally insulated with ceramic insulating modules. This system provides low shell temperatures and helps to retain heat for improved efficiency.
EvenFlo Manifold Insulation
In some cases, the EvenFlo Manifold can be insulated to ensure that the pollutants that enter the oxidizer remain in a gaseous state. If the process constituents should condense at some point in the oxidizer, they can become a maintenance issue, or worse yet, become a hazard to the equipment. Some pollutants will condense and collect on many of the surfaces of the oxidizer, leaving a sticky, tarry substance that is difficult to remove. Insulating our EvenFlo Manifold helps to prevent any condensation, and keeps your process air in a gaseous state.
Shop Assembled up to 15,000 SCFM
Our TRITON Series Regenerative Thermal Oxidizers come shop assembled, pre-piped and wired, and filled with media for units up to 15,000 scfm, which will help reduce the length and expense of installation.
Temperature Safety System
Every TRITON system is integrated with our customized PLC-control panel called TSS Control. TSS communicates with the TRITON System and your process for optimal performance, safety, and reliability. We use our proprietary thermal control logic and multiple temperature inputs to maximize the regenerator thermal efficiency. This unique control technique constantly adjusts valve timing to maximize thermal efficiency without compromise in destruction efficiency.No other supplier goes to these extremes to maximize the performance of their RTO.
