Uniform Temperature Regenerative Thermal Oxidizer Stable Heating Wide Application Range
Overview:
Regenerative furnaces excel in the field of industrial heating. Their high thermal efficiency enables them to significantly reduce energy consumption. The efficient heat storage function of the regenerative body combined with the reversing combustion technology not only improves the utilization rate of heat, but also effectively reduces the emission of pollutants such as nitrogen oxides, meeting environmental protection requirements. The temperature inside the furnace is uniform and stable, and can be widely used in various heating processes in metallurgy, ceramics, glass and other industries. The equipment has a compact structure, is equipped with an advanced automatic control system, is reliable in operation, and is easy to maintain, providing efficient and stable heating support for the company's production.

Product Introduction:
The system is customized for the 100,000 tons/year MMA (methyl methacrylate) unit. It adopts the RTO thermal storage oxidation + waste liquid coordinated incineration process for high-concentration organic waste liquid and process waste gas (including recombinant liquid, biochemical waste liquid, etc.). Through the high temperature of 1100°C, MMA by-products (such as aldehydes and ester organic matter) are completely decomposed, and the waste heat boiler is used to recover the flue gas heat to produce industrial-grade superheated steam, so as to achieve the simultaneous harmlessness of waste liquid and waste gas and energy regeneration. The flue gas is discharged in compliance with the standards after SNCR denitrification and semi-dry desulfurization and dust removal, forming a closed loop of the entire process of "incineration-waste heat-purification", with an annual steam supply value of more than 30 million yuan.
Waste gas treatment capacity: 71,603 Nm³/h (including MMA process waste gas)
Concentrated process waste liquid treatment capacity: 9,600 kg/h
Biochemical waste liquid treatment capacity: 3,000 kg/h
Recombinant liquid treatment capacity: 1,264 kg/h
Steam co-generation: 22 t/h (superheated steam)
Steam parameters: 4.3 MPaG, 435°C (directly used in production cycle)
Footprint: 60m×30m (modular compact design)
Incineration unit: waste liquid incinerator (950-1100°C)
Waste heat recovery: waste heat boiler + high-temperature plate heat exchanger
Purification module: SNCR denitrification, semi-dry scrubber, induced draft fan
Pretreatment: wastewater stripping tower system
Theory:
The RTO is comprised of insulated chambers filled with high-temperature ceramic media. During operation, the polluted air enters the oxidizer through an energy recovery chamber, where the ceramic media preheats it before introducing it to the oxidation chamber. As the air moves through the bed, its temperature rises rapidly. The oxidation reaction takes place in the combustion chamber, converting the pollutant-laden air into CO2 and water vapor, releasing a significant amount of thermal energy.
The hot, clean gas exits through the second recovery bed, leaving the heat in the ceramic media. In the next cycle, the process stream flows in reverse, utilizing the stored heat to preheat the incoming air. By periodically switching the inlet, outlet, and purge processes, the flow changes direction in the oxidizer, completing the preheating, oxidation, heat storage, and release stages. This heat storage process allows the thermal energy released during oxidation to be reused, reducing fuel consumption for preheating.
To maintain optimal heat recovery efficiency, the direction of the process stream is regularly switched using automatic diverter valves controlled by the PLC system.
Advantages:
(1) The single system is compatible with three types of complex media: concentrated waste liquid, biochemical waste liquid, and recombinant liquid. The organic matter removal rate is ≥99.9%, solving the problem of "variable waste liquid components and large fluctuations in calorific value" in the MMA process.
(2) The incinerator can withstand temperatures of up to 1100°C and has a residence time of ≥2 seconds, ensuring that dioxins and difficult-to-degrade components are completely decomposed.
(3) The steam parameters are adapted to the needs of the chemical plant network to reduce secondary heat exchange losses. The floor space is reduced by 15% compared to traditional incineration systems.
(4) It provides an integrated solution of "environmental protection compliance-steam reuse-cost reduction and efficiency improvement" for high-value-added chemical projects such as MMA, helping to achieve the goal of a "near-zero emission" factory.
