Integrated Filtration Housing with Slurrification Nozzles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current filtration processes are space-intensive and require separate vessels for slurrification, leading to difficulties in maintaining the quality of insoluble solids for re-use, especially in applications like edible oil bleaching, where the filter cake is often discharged as a dry lump, making it difficult to re-use and prone to oxygen exposure.
Innovation Solution
A filtration system with an integrated slurrification section within the housing, utilizing nozzles for steam or gas injection to agitate and regulate the slurrification liquid, allowing in-situ slurrification of the filter cake without the need for additional vessels, thus maintaining solid quality and reducing oxygen exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate agitation vessel is used for slurrification, then the slurrification process can be performed, but the space requirements increase and the system becomes more complex
Solution Approach 1:
The patent combines the filtration and slurrification functions into a single filter system. The slurrification section is integrated within the housing of the filter system, eliminating the need for a separate agitation vessel. The filter cake is slurrified in-situ within the same housing where it was filtered, merging two previously separate operations into one unified system.
Solution Approach 2:
The housing of the filter system serves multiple functions: it contains both the filtration elements and the slurrification section. The same housing that filters the liquid-containing-solids also performs the slurrification of the filter cake, making the system multi-functional and reducing the need for additional equipment.
2Productivity
If the filter cake is discharged as a dry lump, then the filtration process is complete, but the solid quality deteriorates and re-use becomes difficult
Solution Approach 1:
The patent performs slurrification as a preliminary action before discharge. Instead of discharging the filter cake as a dry lump and then attempting to slurrify it later, the system slurrifies the filter cake in-situ within the housing before discharge. This preliminary slurrification action maintains solid quality and facilitates re-use by creating a pumpable slurry directly in the filtration housing.
3Reliability
If additional vessels are used for slurrification, then the slurrification can be performed, but the device complexity increases
Solution Approach 1:
The patent merges the filtration and slurrification operations into a single integrated system. The slurrification section is incorporated within the existing housing of the filter system, combining two separate processes into one unified device and reducing overall system complexity.
Solution Approach 2:
The filter system housing is designed to perform multiple functions: filtration and slurrification. By making the housing multi-functional, the patent eliminates the need for additional separate vessels and equipment, thereby reducing device complexity while maintaining slurrification capability.
4Ease of operation
If the filter cake is exposed to oxygen during discharge, then the discharge process is simple, but the solid quality deteriorates
Solution Approach 1:
The patent performs slurrification as a preliminary action before discharge, creating a pumpable slurry within the sealed housing. This preliminary action occurs before the discharge process, allowing the solids to be protected from oxygen exposure during the discharge operation while maintaining their quality for re-use.
Solution Approach 2:
By performing slurrification in-situ within the filtration housing before discharge, the system creates a controlled environment for the solids. The slurry is formed and discharged in a manner that minimizes exposure to atmospheric oxygen, protecting the solid quality without requiring complex inert atmosphere equipment.
