Method and system for producing fuel from waste

Abstract

The invention provides a method and a system for producing fuel oil from garbage. The system for producing fuel oil from garbage comprises a separation device, and further comprises a first pyrolysis device, a second pyrolysis device, a reactor, a cracking device, a condensing device, a liquid storage container, a combustion chamber and a heating device which are sequentially communicated, wherein powdery iron is arranged in the reactor; carbon residues input by the second pyrolysis device and gas output by the condensing device are conveyed to the combustion chamber; and the heating device is used for heating the gaseous components output by the second pyrolysis device. The method and the system have the advantages of high resource utilization rate, good economic benefit, environment protection performance and the like.

Description

technical field [0001] The invention relates to garbage treatment, in particular to a method and system for producing fuel oil from garbage. Background technique [0002] With the rapid development of society and economy, the use of plastics is increasing, and it has increased significantly year by year. China is currently the country that produces, uses and consumes the most plastic products in the world. In 2010, the total output of plastic products in my country was not less than 58.3 million tons, and the per capita plastic consumption was not less than 46 kg. As the consumption of plastic products continues to increase, waste plastics are also increasing. In 2012, my country's waste plastic production was about 34.13 million tons, and the recycling amount was more than 24.878 million tons, accounting for only about 30% of my country's plastic consumption; waste plastics that have not been recycled have caused great pollution to the environment, bringing The long-term ...

In 2012, my country's waste plastic production was about 34.13 million tons, and the recycling amount was more than 24.878 million tons, accounting for only about 30% of my country's plastic consumption; waste plastics that have not been recycled have caused great pollution to the environment, bringing The long-term "white pollution" has not been completely resolved

Since plastics are difficult to degrade naturally for hundreds of years, landfilling will cause serious environmental hazards and waste a lot of energy and resources contained in itself; incineration will produce a large amount of highly toxic substances - dioxins, which have already damaged the environment and serious health hazard
