Dissolved Oxygen Removal Chamber Using Catalyst Ion Exchanger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water treatment methods require additional mechanisms for adding hydrogen or pumps to increase pressure, leading to inefficiencies and potential hydrogen dissipation, and do not effectively address the removal of dissolved oxygen in water.
Innovation Solution
A water treatment method and apparatus utilizing a single bed configuration of a metal catalyst-supported ion exchanger in the dissolved oxygen removal chamber, where hydrogen generated in the cathode chamber reacts with dissolved oxygen to form water, eliminating the need for separate hydrogen addition and pressure boosting, and allowing for efficient dissolved oxygen removal without additional pumps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pump is used to pressurize cathode water for adding to water to be treated, then the cathode water can be added to the water to be treated, but the device complexity increases and power consumption increases
Solution Approach 1:
The patent combines the cathode water discharge function with the water treatment function by configuring the cathode chamber outlet to directly communicate with the water treatment chamber. This eliminates the need for separate pump equipment to transfer cathode water, as the system merges the electrolysis chamber and treatment chamber into an integrated unit where water flows directly from the cathode chamber into the treatment chamber.
Solution Approach 2:
The water treatment chamber serves multiple functions: it treats water to be treated, receives and utilizes cathode water containing hydrogen, and eliminates the need for separate pressure boosting equipment. The system makes the water treatment chamber universal by combining functions that would otherwise require separate components.
2Productivity
If cathode water is added to water to be treated, then hydrogen can be supplied to remove dissolved oxygen, but power consumption increases due to pressure boosting requirements
Solution Approach 1:
The patent creates equipotential conditions for water flow by configuring the cathode chamber and water treatment chamber at the same pressure level, allowing cathode water to flow into the water treatment chamber without requiring pressure boosting. The chambers are connected such that water can move freely between them based on gravity and pressure equilibrium, eliminating the need for energy-consuming pump operations.
Solution Approach 2:
The system makes the cathode water self-service by allowing it to automatically flow into the water treatment chamber without external pressurization. The hydrogen-containing cathode water naturally moves into the treatment chamber where it reacts with dissolved oxygen, making the hydrogen supply self-sustaining and eliminating the need for energy-intensive pressure boosting equipment.
3Quantity of substance
If a pump is used to pressurize cathode water, then hydrogen can be added to water to be treated, but hydrogen dissipation occurs and hydrogen utilization efficiency decreases
Solution Approach 1:
The system enables cathode water to self-flow into the water treatment chamber using gravity and pressure differential alone, without pump pressurization. This self-service mechanism prevents hydrogen dissipation that would occur during pump operation, as the gentle gravitational flow maintains hydrogen in solution while delivering it to where it is needed for dissolved oxygen removal.
