Centrifuge Integrated Coal Storage for Tar Solid Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveying tarry and sticky solids obtained from separating viscous tar suspensions in coking processes is inefficient and costly due to the consistency of the solids, often requiring expensive equipment or prone to device failures.
Innovation Solution
A centrifuge is integrated into the upper part of a coal-storing container, allowing the separated solids to fall by gravity into the storage bin, eliminating the need for external conveyance and using a pump for the liquid tar centrifugate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a centrifuge is used to separate solids from viscous tar suspension, then the separation efficiency is improved, but the solids obtained require complex and expensive conveying equipment due to their tarry and sticky consistency
Solution Approach 1:
The patent combines the centrifuge for solid-liquid separation with the coal storage container into a single integrated unit. The centrifuge is positioned inside the storage container, and the separated solids are deposited directly into the coal mass, eliminating the need for separate conveying equipment to transport solids from the centrifuge to the storage container.
Solution Approach 2:
The system uses the existing coal storage container to receive and store the separated solids directly. The coal mass itself serves as the receiving medium for the solids, and the container's existing structure provides the storage function, eliminating the need for additional dedicated conveying and storage systems for the solids.
2Ease of operation
If conventional conveying methods such as screws or conveyor belts are used to transport the separated solids, then the solids can be moved to coal storage, but the devices are prone to failure and require frequent maintenance due to the sticky nature of the solids
Solution Approach 1:
The patent extracts the solids conveying function from the system entirely by eliminating the need for mechanical conveying equipment. Instead of using screws or conveyor belts to transport solids, the system allows solids to be deposited directly into the coal storage container through gravity, removing the unreliable conveying components from the process.
3Ease of operation
If double-walled high-pressure conveying lines are used to transport the sticky solids, then the solids can be conveyed effectively, but the equipment cost increases significantly
Solution Approach 1:
The patent removes the need for expensive high-pressure conveying lines by extracting the solids conveying function from the system. The integrated centrifuge design allows solids to be deposited directly into the coal storage container, eliminating the requirement for costly specialized conveying infrastructure.
Solution Approach 2:
By merging the centrifuge with the storage container, the system eliminates the need for separate high-pressure conveying lines. The combined design allows solids to be deposited directly into the coal mass through gravity, replacing the expensive conveying infrastructure with a simple integrated structure.
4Adaptability or versatility
If the centrifuge is located outside the coal storage container, then the separation process is independent, but additional conveying equipment is required to transport solids into the storage container
Solution Approach 1:
The patent merges the centrifuge with the coal storage container by positioning the centrifuge inside the container. This integration allows the centrifuge to deposit solids directly into the coal mass without requiring external conveying equipment, while the liquid tar can be pumped out through a separate discharge line, maintaining process functionality while eliminating conveying complexity.

Function Achieved in This Case
This solution simplifies the process by eliminating the need for complex pumping operations, saving energy and equipment costs while ensuring the solids are directly added to the coal storage, enhancing the efficiency of solid utilization in coking processes.
