Tyre Pyrolysis Plants
Waste issues, fuel and environment concerns have created an increased interest in tyre pyrolysis machines. There are vast amounts waste rubber vehicle tyres worldwide, often in huge piles waiting to be processed. Although involving some capital investment, waste tyre pyrolysis plants are an increasingly attractive option. Likely to cost six figures or higher these machines are a large investment, however disposal of rubber tyres has increasing associated costs, and charcoal and biofuel outputs have increasing value both environmentally and as an alternative fuel.
Pyrolysis plants are also used to process different types of waste, such as oil sludge, plastic waste, agricultural waste, municipal solid waste, however tyre recycling is one of the most popular uses.
In continuous tyre pyrolysis plants, valuable materials can be recovered from scrap tyres that would otherwise be incinerated or buried. Both incineration and burial of rubber-based waste has damaging environmental impacts.
A semi-continuous pyrolysis machine has screw automatic feeders as well as a rotary reactor. The intention of the screw automatic feeders is to ensure tyre waste is moved in the reactor chamber without introducing a great deal of air into the closed system. The machines may be operated with a relatively small labour force and are simple to maintain.
Continuous tyre pyrolysis machines have fixed (horizontal) reactors and automatic dischargers. The high level of automation means a reduction in manual labour costs. Furthermore, such machines take advantage of the combustible gas produced during tyre pyrolysis for reactor furnace reheating whilst maintaining state-of-the-art safety functions to ensure a safe working environment.
A continuous rubber pyrolysis plants can generate vast amounts of tyre oil, combustible gas, carbon black, and steel wire daily from waste. The plants can operate 24/7 and are made to maximise oil yields and minimise energy input. Plant configurations can also include automatic grinders.
Emission cleaning modules help reduce emissions. The initial stage cools any smoke using water cooling condensers, in the second stage, smoke cleaning occurs via water spraying, water washing, and ceramic ring adsorption techniques, activated carbon absorption towers and de-dusting finalise the process. This process ensures machines can meet strict emission standards.
