Solution Overview
Problem
Existing decontamination systems face challenges in stably supplying hydrogen peroxide gas to large spaces, leading to condensation issues and corrosion, and are inefficient when dealing with multiple rooms, as they require large diameter ducts and anti-corrosion heaters, and struggle to accurately track gas supply quantities.
Innovation Solution
A decontamination system using a small-diameter supplying pipe to mix hydrogen peroxide water with compression air, which is then gasified near or in each room, eliminating the need for large ducts and anti-corrosion heaters, and allowing for accurate gas supply tracking by increasing the conveyance distance of the gas-liquid mixture pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If large diameter ducts are used to supply hydrogen peroxide gas, then the gas can be supplied to large spaces, but the system becomes complex and requires anti-corrosion heaters
Solution Approach 1:
The patent uses compressed air to atomize and transport hydrogen peroxide solution through small diameter pipes to multiple rooms. The gas-liquid mixture is generated at the source and delivered via pneumatic pressure, eliminating the need for large ductwork and heating systems while maintaining effective decontamination gas delivery.
Solution Approach 2:
The patent changes the physical state and delivery parameters by using compressed air to create a gas-liquid mixture that can be transported through small pipes. This parameter change allows the system to deliver the required quantity of decontamination gas without requiring large diameter ducts or anti-corrosion heaters.
2Adaptability or versatility
If hydrogen peroxide gas is supplied through long ducts to multiple rooms, then multiple rooms can be decontaminated, but condensation occurs and supply accuracy decreases
Solution Approach 1:
The system uses compressed air to transport the gas-liquid mixture through small diameter pipes to multiple rooms simultaneously. The pneumatic delivery system maintains mixture integrity throughout the distribution network, preventing condensation and ensuring reliable delivery to each room without requiring long heated ducts.
Solution Approach 2:
The patent segments the delivery system into individual branches for each room, with each branch receiving the gas-liquid mixture through separate small diameter pipes. This segmentation allows independent control and delivery to multiple rooms while maintaining mixture stability and preventing condensation in each branch.
3Device complexity
If small diameter pipes are used to supply gas-liquid mixture, then the system is simpler and cheaper, but the conveyance distance is limited
Solution Approach 1:
The patent uses compressed air to provide the driving force for transporting the gas-liquid mixture through small diameter pipes over extended distances. The pneumatic pressure overcomes the limitations of small pipe diameter, enabling conveyance to multiple rooms while maintaining system simplicity and avoiding the need for large ductwork.
4Measurement precision
If hydrogen peroxide water is supplied directly without mixing with compressed air, then the supply quantity can be tracked accurately, but the gasification efficiency decreases
Solution Approach 1:
The patent uses compressed air to atomize the hydrogen peroxide solution, creating a fine gas-liquid mixture that gasifies efficiently upon contact with surfaces or in the air. The compressed air delivery system allows accurate measurement and tracking of the supplied solution quantity while simultaneously enhancing gasification efficiency through atomization.
