Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ozone decomposition units are inefficient in decomposing large amounts of ozone water, as they require a long time to heat the ozone water to the necessary temperature for decomposition.
Innovation Solution
The proposed solution involves an ozone decomposition unit with a tank, a liquid supply pipe, and a heating member, where the ozone water is introduced into a tank already filled with heated liquid, allowing for rapid temperature increase and ozone decomposition, and includes a controller to manage valve operations for efficient ozone water circulation and discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ozone water is heated by a heater installed in a circulation pipe, then ozone decomposition is achieved, but the heating time becomes excessively long for large amounts of ozone water
Solution Approach 1:
The invention applies preliminary action by pre-heating liquid in the tank before introducing ozone water. The heating member heats the liquid in advance, so when ozone water is introduced, it immediately contacts the heated liquid and rapidly increases in temperature, eliminating the need for prolonged heating of the entire ozone water volume.
Solution Approach 2:
The invention uses an intermediary substance (the liquid in the tank) to transfer heat to the ozone water. Instead of directly heating the ozone water with a heater in the circulation pipe, the heating member heats the liquid, which then acts as a heat transfer medium to rapidly warm the ozone water upon contact.
2Quantity of substance
If the volume of the tank is increased to handle large amounts of ozone water, then decomposition capacity is improved, but the heating time increases proportionally
Solution Approach 1:
By pre-heating the liquid in the tank before ozone water introduction, the system maintains rapid heating capability even as tank volume increases. The heated liquid reservoir scales with the tank, ensuring that larger volumes of ozone water can be processed without proportionally increasing heating time.
Solution Approach 2:
The liquid in the tank serves as a thermal buffer and heat transfer intermediary that scales with tank volume. As the tank volume increases, the volume of pre-heated liquid increases proportionally, maintaining the rapid heat transfer capability and preventing heating time from increasing with processing capacity.
3Productivity
If a circulation pipe with heater is used for ozone water heating, then continuous circulation and decomposition are achieved, but the heating efficiency is insufficient for rapid decomposition
Solution Approach 1:
The heating member performs preliminary heating of the liquid in the tank, creating a reservoir of thermal energy. This concentrated heating approach is more efficient than circulating and heating ozone water through a pipe, as it pre-concentrates the thermal energy in the tank before ozone water introduction.
Solution Approach 2:
The liquid in the tank acts as a heat transfer intermediary that improves heating efficiency. The heating member heats this intermediary liquid, which then rapidly transfers heat to the ozone water upon contact, achieving faster and more efficient decomposition compared to direct circulation heating.
