Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coke quenching methods result in non-uniform temperature distribution and high water content in coke batches, leading to inefficient cooling and potential damage to downstream processing equipment, as well as reduced product quality due to elevated water content in raw iron production.
Innovation Solution
A receiving container with structural members producing unevenness of at least 20 mm on its bottom, which breaks up the coke batch upon sliding, increasing its inner surface area and allowing more efficient water penetration and cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional quenching methods are used, then the coke batch can be cooled, but the temperature distribution becomes non-uniform and water content becomes elevated
Solution Approach 1:
The coke batch is segmented into smaller pieces through mechanical breaking up in the receiving container. This segmentation increases the total surface area of the coke, allowing water to penetrate more uniformly throughout the batch during quenching, thereby achieving uniform temperature distribution and reducing excessive water content
Solution Approach 2:
The coke batch undergoes preliminary mechanical breaking up and surface area enhancement in the receiving container before the quenching process begins. This preliminary action prepares the coke structure to accept water more effectively, ensuring uniform cooling and preventing non-uniform temperature distribution and elevated water content
2Stability of the object's composition
If the coke batch is compacted, then it maintains structural integrity, but water penetration during quenching is reduced
Solution Approach 1:
The compacted coke batch is segmented into smaller pieces with increased surface area in the receiving container. This segmentation creates more pathways for water penetration while maintaining the overall structural integrity of the coke batch, allowing effective quenching without compromising structural stability
Solution Approach 2:
The coke structure is transformed from a compacted three-dimensional mass into a more dispersed configuration with increased surface area in the receiving container. This dimensional change enhances water penetration capabilities while preserving the essential structural characteristics of the coke
3Temperature
If high water content is present in coke, then cooling is achieved, but raw iron production quality is reduced
Solution Approach 1:
The coke is segmented into smaller pieces with increased surface area, enabling uniform water distribution during quenching. This segmentation ensures that water is absorbed uniformly throughout the coke batch, achieving effective cooling while preventing excessive water content that would compromise raw iron quality
Solution Approach 2:
The physical parameters of the coke batch are changed through mechanical breaking up and surface area enhancement. These parameter changes optimize the coke structure for uniform water absorption, achieving efficient cooling while maintaining water content levels that preserve raw iron production quality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method ensures uniform cooling and reduced water content in the coke, improving the quality of raw iron and reducing the risk of equipment damage, thereby enhancing the economic efficiency of the coking process.
Implementation Method 1
at least one structural member producing unevenness of a min. height of 20 mm is arranged on the bottom of the receiving container. The coke cake pushed from the coke-oven chamber slips out of the coke-oven chamber during the pushing operation and slides across the structural member such that on account of its unevenness the structural member breaks up the coke batch by the weight and the kinetic energy of the coke batch
Implementation Method 2
into these gap-like cavities an increased amount of water can flow towards the inside of the coke batch during the subsequent cooling process with water
Implementation Method 3
the coke is quenched with water. For this purpose, the water is sprayed vertically downwards onto the hot coke cake from an available storage tank

AI summary
A device for increasing the interior surface of a compact coke charge in a receiving trough, which device increases the interior surface of a coke cake or coke leaving the coking chamber by mechanically breaking apart or roughening it, resulting in a break-up of the coke structure and the formation of crevice-type cavities in the compacted coke charge so that an increased amount of water can flow into the interior of the coke charge during the subsequent quenching step through these crevices, resulting in a high profitability of the method due to reduced quenching times and lower water consumption. A method for increasing the interior surface of a compact coke charge in a receiving trough, which serves to break up a fresh coke cake or to roughen the coke in order to reduce water consumption during quenching is disclosed.
