Abstract

The present invention relates to a method for raising strength of metallurgical coke and its system. Said invention adopts traditional coking process and equipment, and adds waste plastics in the course of coking process, and is characterized by that after the waste plastics and additive are processed, they are added into coking furnace to implement co-coking with coking coal, at the same time of that the waste plastics are charred at high temp., and converted into coke, tar and gas the coke quality can be improved, crushing strength of coke M40 can be raised, abrasive resistance index of coke M10 is reduced, coke reactivity CPI is reduced and coke postreaction strength can be raised. Said system includes waste plastics processing system, additive and waste plastics mixing system, waste plastics and additive mixture and coking coal mixing system and traditional coking system.

Description

[0001] Said field: [0002] The invention belongs to waste plastic treatment technology and equipment and a method for improving the strength of metallurgical coke, in particular to a method and equipment for co-coking waste plastic and coal to improve coke strength. Background technique: [0003] With the rapid development of world economy and science and technology, the improvement of people's material living standards and the acceleration of urbanization, the output of urban solid waste has increased sharply. According to statistics, the current annual output of municipal solid waste in my country has exceeded 150 million tons, and is growing at a rate of 8% to 10% every year. About 2 / 3 of the cities in our country are surrounded by garbage. The waste plastics in my country's municipal solid waste accounts for about 4% to 10% of the total garbage, with an annual output of 5 to 6 million tons, and is growing at a rate of nearly 8% to 9% every year. [0004] At present, my ...
