Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for recycling waste plastic in coke ovens do not provide specific carbonization conditions for processing large amounts of waste plastic without coal, leading to inefficiencies and incomplete carbonization.
Innovation Solution
A method for recycling waste plastic in a coke oven by charging it to a predetermined maximum height exceeding half the oven width, determining a coking time based on a relational expression involving the maximum height and chamber temperature, and using a coke pusher machine to discharge completed coke, ensuring thorough carbonization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If waste plastic is charged to a large amount to process efficiently, then productivity is improved, but carbonization completeness deteriorates due to insufficient knowledge of suitable carbonization conditions
Solution Approach 1:
The invention changes the parameters of carbonization by establishing specific relationships between charge height, coking time, and chamber temperature. By setting the charge height to exceed half the oven width and determining coking time through the derived relational expression, the invention ensures complete carbonization while processing large amounts of waste plastic efficiently.
2Adaptability or versatility
If existing coke oven methods are used without established carbonization conditions, then device utilization is improved, but manufacturing precision deteriorates due to lack of specific process parameters
Solution Approach 1:
The invention provides specific process parameters for using existing coke ovens for waste plastic carbonization. By establishing the relational expression between charge height, coking time, and chamber temperature, and setting the charge height to exceed half the oven width, the invention enables precise control of carbonization in existing equipment without requiring new facilities.

AI summary
Provided is a method for producing a recycled product of a waste plastic, whereby it becomes possible to recycle a large amount of waste plastics. The method for producing a recycled product of a waste plastic comprises: charging the waste plastic in a coke oven at a predetermined maximum height of charge that is a height more than half of the width of the coke oven; performing carbonization for a predetermined coking time to produce a coke, tar, light oil, and gas; and removing the coke from the coke oven using a coke pusher machine. In the method, the value of the predetermined coking time is obtained by determining a relational expression between a maximum height of waste plastic charge and a coking time required for the completion of the carbonization and then calculating the predetermined coking time by substituting the predetermined maximum height of charge into the relational expression.
