Explosion Proof Regenerative Thermal Oxidizer For Sale Negative Pressure Operation Fully Automatic

Explosion Proof Regenerative Thermal Oxidizer Negative Pressure Operation Fully Automatic Control

Overview:

A regenerative furnace is a device that stores and releases thermal energy through a heat storage body (such as ceramics). It uses the waste heat of high-temperature flue gas to preheat the combustion air, significantly improving combustion efficiency. It is suitable for high-energy-consuming industries such as steel and glass, and the energy saving rate can reach more than 30%.

Product Introduction:

The system is specially designed for low-concentration VOCs waste gas and organic waste liquid in the n-butane process of producing maleic anhydride/anhydride in the chemical industry. It adopts the three-stage coordinated process of RTO thermal storage oxidation + TO high-temperature incineration + waste heat recovery to achieve the simultaneous harmlessness and energy conversion of waste gas and waste liquid. Through the efficient heat exchange of multi-chamber thermal storage body and deep decomposition in the high-temperature section (800-1000°C), VOCs and harmful substances are ensured to be completely mineralized. At the same time, the integrated waste heat boiler converts the incineration heat into industrial steam, forming a closed-loop model of "waste treatment and energy self-sufficiency". The annual economic benefits of a single system can reach 135 million yuan.

Waste gas treatment capacity: single system treatment capacity ≥ 70,000 m³/h (low concentration VOCs waste gas)
Waste liquid treatment capacity: compatible with small amounts of high COD waste liquid co-treatment
‌Thermal efficiency‌: thermal storage efficiency ≥ 95%, system comprehensive heat recovery rate ≥ 85%
Steam output: customized according to working conditions, typical value ≥ 5 t/h (saturated steam)
‌Emission indicators‌: VOCs purification rate ≥ 99%, dioxin < 0.1 ng TEQ/m³
‌Applicable industries‌: chemical industry (maleic anhydride, acetic anhydride, etc.), petrochemical, pharmaceutical

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) ‌Win-win situation of efficient purification and economic benefits:
‌Adopting RTO+TO process coupling, thermal storage oxidation (RTO) pre-decomposes low-concentration waste gas, and high-temperature incineration (TO) strengthens the treatment of difficult-to-degrade components. The VOCs removal rate is ≥99%, and the cost of waste gas compliance is reduced by 40%. The waste heat boiler recovers the incineration heat, with an annual steam value of more than 100 million yuan and an investment payback period of ≤3 years.

‌
(2) ‌Compact integration and low-cost operation and maintenance:
Modular design, the floor space is reduced by 30% compared with traditional split equipment, suitable for plant space-constrained scenarios. Fully automatic control, gas consumption is reduced by 25%, and the operation and maintenance manpower requirements are reduced by 50%.

(3) ‌Industry-leading technical verification:
The domestic market share ranks first, and has been successfully applied to 40+ large-scale thermal storage incineration projects (processing capacity > 70,000 m³/h). Adapting to the characteristics of chemical process waste gas such as n-butane and phthalic anhydride, it solves the corrosion problem of sulfur-containing and halogen-containing waste gas.

(4) ‌Environmental protection and safety double guarantee‌:
The incineration tail gas undergoes rapid cooling + activated carbon adsorption + SCR denitrification, and the emission index is stricter than the GB 31571-2015 standard. Explosion-proof design + negative pressure operation eliminates the risk of flammable gas leakage.

R&D and Production:
