What is the gas treatment/recovery system you have for pyrolysis machine?

Pyrolysis plant is a popular waste to energy recycling project all over the world. Installing a legal and formal pyrolysis plant, how to properly and reasonably treat the gas generated during the pyrolysis process and the combustion is crucial. The gas treatment and recovery of pyrolysis machine mainly involves multiple links and technologies to ensure environmental protection and safety. ‌

There are mainly two possible gases generated in the working process of pyrolysis machine except pyrolysis oil gas, one is the uncondensable combustible gas, namely syn-gas, and the other is the exhaust gas.

1. Pyrolysis syn-gas recovery system

The main components of pyrolysis sysn-gas are non-condensable but highly flammable hydrocarbon gases such as C1, CH4, C2H4, C2H6, and C3H8. The calorific value is 35MJ/m3, which is equivalent to natural gas and has a high utilization value. Under normal circumstances, the syn-gas can be recycled to heat the pyrolysis machine reactor to save other fuels after purification.

This practice not only improves energy utilization efficiency, but also helps to reduce dependence on external energy and reduce the operating costs of pyrolysis machine.

2. Pyrolysis exhaust gas treatment system

However, the exhaust gas after pyrolysis also contains a small amount of polluting waste gas such as H2S, COx, NOx, and SOx, which needs to be treated with special exhaust gas treatment system. The detailed exhaust gas treatment equipment include a desulfurization and deodorization tower system, which uses alkali spraying and alkali water seal devices to purify and deodorize the exhaust gas, effectively remove polluting gases such as H2S in the exhaust gas, and achieve the purpose of purifying and deodorizing the exhaust gas.‌

DOING pyrolysis machine has a patented smell disposal system with the newly invented catalyst. It can effectively remove H₂S from exhaust gas and guarantee no pollution from gas burning.

In addition, the desulfurization and dust removal tower system can also be used for treatment. The system introduces dusty exhaust gas into the desulfurization tower through an induced draft fan, and achieves the purpose of desulfurization through multi-layer spraying and fillers. At the same time, it absorbs smoke and ensures that emissions meet environmental standards. ‌

In actual applications, tire manufacturers usually adopt a comprehensive strategy to treat waste gas, such as using fully continuous pyrolysis machines or closed technology to seal the equipment in the production process to reduce waste gas generation, and then collect and purify it in depth to ensure that the emissions meet the emission standards.
