EPS blowing agent industry

1. Application industry
Household appliances packaging, fragile packaging, insulation, building materials
2. Industry characteristics
①VOCs have a single composition and are easy to accumulate in high concentrations. Generally, it is Styrene and Penthane.
②VOCs are volatilized during transportation, production and after completion. It is easy to accumulate concentration in a certain location, causing safety risks.
③After the production is completed, it needs to stand for a certain period of time, and during the standstill period, it needs to be temporarily stored in a special warehouse. Temporary storage is also stored
Increased concentration of VOCs creates safety risks.
④ As VOCs volatilize in the temporary storage, the relative humidity of the air will decrease, which makes it easier to generate static electricity.
3. Solution
① During the production and feeding process, a special ventilation device is installed, and the feeding device needs to be ventilated in time to reduce the concentration to prevent VOCs from gathering and exploding.
②In the process of using steam foaming, the mixture of steam and VOCs produced needs to be removed from the water while maintaining proper
The relative humidity can prevent the humidity from being too low and generating static electricity to cause explosion.
③The temporary storage warehouse is equipped with explosion-proof fans, and the LEL device detects the concentration to control the fans, and draws air in stages to reduce the concentration to ensure the safety of the temporary storage. Because of the low volatilization rate of VOCs in the temporary storage and the discontinuous exhaust air, it is not suitable for continuous introduction of RTO treatment.
④The temporary storage warehouse is equipped with a humidity detection device, and the relative humidity of the temporary storage warehouse is maintained at 100% by detecting the humidity to control the humidification device.
⑤ All waste gas collection must be uniform and effective to prevent waste gas from gathering at one point.
⑥ All production equipment, warehouses, tools, labor protection supplies, capture pipelines and environmental protection equipment need anti-static measures.
4. Features of the new three-tower RTO
Incorporating advanced core valve technology in the United States, Ausiyi successfully developed a new three-tower RTO with a processing efficiency of 99.5%.
①Economy: Adopting advanced technology of the US headquarters, the US and China are listed simultaneously, both of which are foreign brands, and the investment and operating expenses are the same as the RTO of the two towers.
②Modular design: AuSSE uses many years of 3D design experience to modularize the equipment, which can be quickly installed and debugged, and uses the advantages of 3D visualization for humanized design.
③The processing efficiency adopts the unique valve structure that AuSSE has always been proud of. There are only two actuators. The structure is simple and easy to maintain. The valve switching speed is less than 1S. The valve is equipped with an active sealing device to automatically compensate for the loss of the sealing material due to fatigue. The leakage phenomenon, combined with the comprehensive effect of the third tower, ensures that the treatment efficiency can reach more than 99.5%, and the efficiency is balanced. Compared with the traditional three-tower RTO discharge speed, the fluctuation is very small!
④Finite element analysis: to verify the rationality, safety and economy of the design by means of finite element analysis. Equipment safety: AuSSE has unparalleled 40 years of RTO design and operation experience: It uses methods such as setting up emergency exhaust valves and supplementing fresh air to ensure the safe and efficient operation of the system. At the same time, the inside of the system is always connected to the atmosphere. Greatly improve system security.
⑤ Burner module: As the heart of RTO equipment, the burner is an important basis for reflecting the stability of RTO equipment to a certain extent. Using low-nitrogen, high-efficiency burners, on the one hand, better combustion parameters can be obtained by adjusting the combustion air and combustion head, and on the other hand, energy consumption and secondary pollution can be effectively reduced.
⑥Intelligent control: Based on big data, with VPN function, it can carry out remote warning, accumulate operating parameters, and operate intelligently.
