Flexible packaging printing industry

1. Application industry:
Food packaging, book printing, banknote printing, consumer product packaging materials
 
2. Industry characteristics:
① The VOCs concentration is higher than 500-5000mg/m3, and the printing quality is directly related to the VOC concentration. The better the quality, the higher the concentration;
② There are many unorganized emissions of VOCs. The printing press pursues high efficiency. It is easy to leak VOCs at the entrance and exit. Factors such as people walking in the space and the placement of goods can easily affect the airflow, which is not conducive to organized capture. Only in the drying area can be effectively captured.
③When increasing the concentration and reducing the wind, the concentration easily exceeds the lower explosive limit. When the printing equipment is working at high speed, static electricity is easy to generate, which can cause safety hazards and explosion accidents.
④Due to the high quality requirements of printing, high-concentration VOCs are not suitable for condensation recovery, and the recovered organic solvents cannot be recycled.
 
3. Solution:
 ①Design the RTO according to  concentration to prevent the RTO from frequently stopping work when the temperature is overheated, which will affect the production.
 ② Carry out closed operations in unorganized discharge areas to prevent VOCs from expanding to other areas as much as possible.
 ③When increasing the concentration and reducing the wind, configure the LEL control device. When the VOCs concentration exceeds the set value, interlocking operation can be performed.
 ④The production equipment and environmental protection system need anti-static treatment.
 ⑤As most of the high-concentration VOCs do not have the value of recycling, they can be used as RTO fuel when RTO is used.
Thereby reducing fuel operating costs.
 ⑥RTO outlet heat can provide heat supplement for other occasions. For example: canteen hot water, dormitory heating, employee baths, etc.
 
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.
