Industry characteristics:
1. In the production process, high concentration of waste gas and low concentration of waste gas are produced. Only incineration treatment, investment and operation cost is high.
2. The composition of waste gas is complex, containing polymer, forming solid substances after temperature change, easy to block environmental protection equipment, poor operation.
3. Waste heat supply process equipment of incineration equipment, which requires high stability of waste heat.
4. For projects that have been put into production, it is difficult to improve environmental protection due to space and other factors.
5. The comprehensive concentration of exhaust gas emissions is large, the expansion of production and capacity, and the treatment efficiency of environmental protection system is high
• Solutions:
1. The waste gas sources are classified, and the low concentration concentration is followed by RTO, and the high concentration is directly followed by RTO. Save 20% on investment cost and 15% on running cost.
2. The pretreatment methods of cooling, filtration and warming are adopted to intercept the polymer to the maximum extent, prevent it from entering the RTO equipment and avoid the blockage of the heat storage ceramics. The life of thermal storage ceramics is extended by more than 3 times.
3. Accurately calculate the heat balance process, the heat of the production line is stable, and the shutdown rate is reduced by more than 60%.
4. Adopt new three-tower RTO structure, reducing volume by 25% and weight by 20%. And can be installed on the roof.
5. The treatment efficiency of the new three-tower RTO can reach more than 99.5%. Compared with the traditional RTO, the emission concentration can be reduced by at least 15mg/m3. The comprehensive emission concentration runs below 10mg/m3.
• New three-tower RTO features:
With the integration of American core valve technology, Aussie has successfully developed a new 3-tower RTO with a processing efficiency of 99.5%.
① Economy: The US headquarters technology is adopted, the US and China are listed simultaneously, the same as a foreign brand, the investment and operating costs are the same as the two tower RTO.
(2) Modular design: AuSSE uses many years of three-dimensional design experience, the equipment modular design, can be quickly installed and debugging, and the use of three-dimensional visualization advantages for humanized design.
(3) Processing efficiency using AuSSE has been proud of the unique valve structure, only two actuators, simple structure and easy maintenance, valve switching speed < 1S, valve set active sealing device, automatic compensation sealing material due to fatigue loss caused by leakage phenomenon, combined with the comprehensive effect of the third tower, so as to ensure that the processing efficiency can reach more than 99.5%, And the efficiency is balanced, compared with the traditional three-tower RTO emission speed fluctuation is minimal!
④ Finite element analysis: Through finite element analysis and other ways to verify the rationality of the design, safety, economy. Equipment safety: AuSSE has 40 years of experience in RTO design and operation: the use of emergency exhaust valve, fresh air and other methods to ensure the safe and efficient operation of the system, while the system is always connected with the atmosphere, greatly improve the safety of the system while reducing safety accessories.
⑤ Burner module: Burner, as the heart of RTO equipment, is an important basis to reflect whether RTO equipment is stable to a certain extent. The use of low nitrogen, efficient burner, on the one hand, can obtain better combustion parameters by adjusting the combustion air and combustion head, on the other hand, can effectively reduce energy consumption and secondary pollution.
⑥ Intelligent control: Based on big data, with VPN function, remote warning, accumulation of operating parameters, intelligent operation.
