The aluminum foil in the composite packaging of pharmaceutical aluminum foil has a high recycling value. Through pyrolysis and oil refining and extracting aluminum blocks, resources can be recycled. This method not only reduces the pollution of waste to the environment, but also provides strong support for sustainable development.
Advantages of pyrolysis treatment of waste aluminum foil
1. Resource recycling:
Through pyrolysis treatment, the aluminum in the aluminum foil packaging can be extracted and put into production again, reducing the pressure on the exploitation of natural resources. For example, the most suitable pyrolysis final temperature of waste aluminum foil is 450℃, and the oil yield is approximately between 60% and 80% depending on the type of aluminum foil. The obtained pyrolysis oil can be recycled, and the extracted aluminum blocks can also be used in various industrial production.
2. Environmental protection and pollution-free:
When processing aluminum foil paper for pharmaceutical packaging, the waste aluminum foil cracking equipment can effectively recycle aluminum and reduce pollutant emissions.
3. Technological breakthrough:
Some waste aluminum foil cracking equipment has overcome the technical problem of wall sticking, and is also equipped with tail gas combustion and recycling devices, which further improves the utilization rate of aluminum alloys.
Working principle of waste aluminum foil cracking equipment
1. Feeding:
Put the waste aluminum foil into the automated cracking processor (reactor).
2. Heating cracking:
After heating, the waste aluminum foil is cracked into oil and gas, non-condensable gas, carbon black and aluminum at high temperature.
3. Oil and gas treatment:
The oil and gas are cooled into liquefied oil through the condensation system, and the non-condensable oil and gas can be directly recovered and burned for heating the cracker.
4. Aluminum block extraction:
After the cracking is completed, the oil and gas are out, and the aluminum in the reactor is cleaned up and prepared for the next round of cracking and refining.
In this way, not only can aluminum and pyrolysis oil be effectively recovered, but also the impact on the environment can be significantly reduced, promoting the sustainable use of resources.
