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.

Ruiding has established the jiangsu province clean incineration
resource engineering technology center and the key laboratory of
the JICUI-Ruidings joint innovation center.
This laboratory is equipped with advanced detection equipment such as
ICP inductively coupled plasma emission spectrometry, atomic
