Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current resin ion exchange devices for water treatment face issues such as complex pretreatment procedures, high resin consumption, large equipment investment, and poor regeneration efficiency, which hinder continuous operation and damage the performance of magnetic powder resin due to its small particle size and low density.
Innovation Solution
A continuously flowing, inner circulatory, quasi-fluidized-bed reactor design that includes a main body casing, inclined pipe separator, and a reducing fluidization tank to maintain efficient contact between magnetic powder resin and water, allowing for continuous separation and regeneration without resin loss, reducing resin consumption, and enabling automatic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fixed beds or suspension beds are used for magnetic powder resin, then resin separation can be achieved, but strong bed resistance, jamming, and break-up of resin particles occur due to small particle size and low density
Solution Approach 1:
The patent changes the operational parameters from traditional fixed bed or suspension bed modes to a quasi-fluidized bed mode with controlled upward flow velocity. This parameter change allows the resin particles to remain suspended without excessive velocity that would cause break-up, while maintaining effective separation through controlled fluidization
Solution Approach 2:
The system transitions from static fixed bed to dynamic quasi-fluidized bed operation, where the resin particles are continuously circulated between the reaction zone and separation zone. This dynamic operation prevents particle jamming and break-up while maintaining separation efficiency
2Productivity
If magnetic powder resin is used in water treatment, then treatment time is reduced and resin consumption is lowered, but traditional reactors cause resin loss during backwash and cannot实现 continuous operation
Solution Approach 1:
The patent implements continuous operation by eliminating the traditional backwash step. Resin particles are continuously circulated between the reaction zone and the inclined pipe separator, maintaining constant treatment capability without interruption or resin loss. The system operates continuously with the resin remaining within the reactor throughout the process
Solution Approach 2:
The patent extracts and eliminates the harmful backwash operation from the treatment process. By using the inclined pipe separator to continuously separate and return resin particles, the system removes the need for periodic backwashing that causes resin loss, thereby preserving the resin within the system
3Reliability
If conventional resin ion exchange devices are used, then water treatment can be performed, but complicated pretreatment procedures and large equipment investment are required
Solution Approach 1:
The patent merges the reaction zone and separation zone into a single integrated reactor system. The magnetic powder resin performs both ion exchange/adsorption in the reaction zone and automatic separation in the inclined pipe separator, eliminating the need for separate pretreatment steps and reducing equipment complexity while maintaining treatment effectiveness
