Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purification devices fail to ensure complete purification of contaminated gas containing microparticles, as the microparticles within bubbles do not effectively mix with decontamination solution, leading to incomplete purification.
Innovation Solution
A mixing nozzle with a throat section, diffuser section, gas and liquid nozzle sections, and a baffle plate that accelerates and reverses the mixed flow to separate and mix microparticles with decontamination solution by centrifugal force, ensuring thorough purification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional air purification devices use simple gas-liquid contact methods, then device complexity is low, but microparticles in bubbles cannot effectively contact decontamination solution resulting in poor purification effectiveness
Solution Approach 1:
The mixing nozzle is divided into multiple functional sections: gas nozzle section, liquid nozzle section, throat section, and diffuser section. Each section performs a specific function - the gas nozzle introduces contaminated gas, the liquid nozzle introduces decontamination solution, the throat section creates high-velocity mixed flow, and the diffuser section expands the flow to enhance mixing. This segmentation allows the device to achieve effective microparticle purification through controlled fluid dynamics while maintaining reasonable structural complexity.
2Productivity
If gas and solution are simply mixed without flow control, then device complexity is low, but mixing efficiency is poor resulting in incomplete purification
Solution Approach 1:
The invention utilizes pneumatic and hydraulic principles to control gas and liquid flow. The gas nozzle section and liquid nozzle section are designed to introduce gas and solution at specific velocities and angles. The throat section creates a high-velocity mixed flow regime that enhances turbulence and mixing efficiency. The diffuser section then expands the flow to maintain mixing while reducing velocity. This pneumatic-hydraulic control system achieves high mixing efficiency for microparticle purification with moderate device complexity.
3Reliability
If microparticles remain in bubbles during purification, then device complexity is low, but decontamination solution cannot contact microparticles resulting in poor purification
Solution Approach 1:
The invention employs dynamic flow control to break microparticles from bubbles. The throat section creates high-velocity mixed flow that generates strong turbulence and shear forces, dynamically breaking up the bubble structure and releasing trapped microparticles. The diffuser section then expands the flow to maintain the disrupted state while allowing thorough contact between decontamination solution and microparticles. This dynamic approach ensures effective purification with moderate device complexity.

AI summary
To provide a mixing nozzle capable of efficiently mixing gas and solution. The mixing nozzle 40 has a throat section 41, a diffuser section 42, a gas nozzle section 43, a first liquid suction port 44, a liquid nozzle section 45, a second liquid suction port 46, a baffle plate 47, and a jetting port 48. The first liquid suction port 44 liquidly absorbs the solution in the water storage pool from a side of the gas nozzle section 43 toward the gas nozzle tip 43a. The liquid nozzle section 45 extends to the downstream side of the gas nozzle section 43 with intervening the first liquid suction port 44. The second liquid suction port 46 liquidly absorbs the solution in the water storage pool from a side of the liquid nozzle section 45 toward the liquid nozzle tip 45a. The baffle plate 47 is provided such that the mixed flow mixed in the diffuser section 42 collides in front of a downstream end of the diffuser section 42, and divides and reverses the mixed flow such that high-speed reversed flow of the mixed flow is formed and the gas and the solution are mixed by centrifugal force.
