High Temperature Direct Fired Thermal Oxidizer Decomposition Pollution Control Energy Regeneration
Overview:
Modern direct-fired furnaces are deeply integrated with the Internet of Things technology, and fully automated control is achieved through PLC or DCS systems, which monitor the combustion status, temperature curve and energy consumption data in real time. Users can adjust parameters through remote terminals to prevent overload or flameout risks. This intelligent management not only improves safety, but also reduces manual intervention, and is particularly suitable for precision manufacturing fields that require a stable heat source (such as semiconductor packaging and lithium battery drying). At the same time, the fault self-diagnosis function greatly reduces the difficulty of maintenance and downtime.

Product Introduction:
The system is a 150,000 ton/year CHP propylene oxide project. It adopts an integrated process of high-temperature oxidation + waste heat cascade utilization for highly complex and high-concentration petrochemical waste gas/wastewater (including propylene derivatives and reaction by-products). Through the thorough decomposition of organic matter at a high temperature of 1200°C, the membrane wall boiler is used to recover heat to produce industrial-grade superheated steam, achieving the dual goals of pollution control and energy regeneration. The system is adapted to my country's first independent CHPPO technology, providing environmental protection technology guarantee for the extension of the propylene oxide industry chain, and the annual steam reuse value exceeds 100 million yuan.
Waste gas treatment capacity: 40,000 Nm³/h (including complex component petrochemical waste gas)
Wastewater treatment capacity: 2.1 t/h (high-concentration organic wastewater)
Superheated steam output: 39 t/h
Steam parameters: 4.0 MPaG, 425°C (directly used in production process)
Floor area: 60m×30m (intensive module design)
Theory:
The Direct Thermal Oxidizer (DTO) first heats the combustion chamber temperature to the set level using fuel. Then, VOCs is introduced into and decompose into CO2 and water at high temperatures, releasing a significant amount of heat. Simultaneously, external equipment such as heat exchangers and boilers recover the thermal energy carried by the purified high-temperature flue gas to achieve energy savings and reduce consumption.
Ruiding can comprehensively design the system based on factors such as the airflow, composition, concentration of the VOCs to be treated, and the desired removal efficiency. Tailored, cost-effective VOCs treatment solutions are provided. When the concentration of the waste gas to be treated is high enough, it's possible to operate without fuel input. The furnace temperature can be maintained by the self-sustaining at moderate Lower Explosive Limits (LELs).
Advantages:
(1) The incinerator can withstand a temperature of ≥1200°C, a residence time of ≥2 seconds, and a decomposition rate of VOCs and toxic byproducts (such as aldehydes) of ≥99.9%. The waste gas/wastewater synergistic treatment solves the problems of "multiphase flow, high salt content, and easy coking" in petrochemical processes.
(2) The thermal efficiency of the membrane wall boiler is ≥85%, and the annual steam output is ≈340,000 tons (4.0MPaG/425°C). It can directly drive production equipment, and the annual energy saving benefits exceed 80 million yuan. The original "economizer + air preheater" multi-stage heat exchange reduces the comprehensive energy consumption by 30% compared with the traditional design.
(3) The flue gas treatment adopts the combination of "bag dust removal + SCR denitrification", with particulate matter <10 mg/m³ and NOx <50 mg/m³, which is better than the special emission limit. The COD removal rate of the wastewater after high-temperature oxidation is ≥99.5%, without the risk of secondary pollution.
(4) Fully automated control, gas consumption <3.5 Nm³/ton steam, operation and maintenance costs reduced by 40%.
(5) Supporting the industrial application of my country's first set of CHPPO technology, solving the environmental protection supporting problems of propylene oxide process. The localization rate of core thermal oxidation equipment is 100%, breaking the cross-technology monopoly.
