Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing fire-retardant gels from dry base powders often result in incomplete hydration and clumping of powder particles due to limited pressure output and inadequate metering techniques, which hinder the optimization of fire-retardant properties.
Innovation Solution
A system and method involving the metering of powder particles into a pressurized air stream for fluidization, followed by injection into a pressurized water stream, where the air pressure is greater than the water pressure to enhance hydration and prevent clumping, using a mixing chamber to physically constrain and mix the fluidized powder with water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If prior art eductor systems are used to mix powder and water, then mixing is achieved, but incomplete hydration and clumping of powder particles occur
Solution Approach 1:
The powder is fluidized in the air stream before contacting water, pre-dispersing individual particles and preventing clumping before hydration occurs. This preliminary fluidization action ensures each particle is ready for complete hydration upon water contact.
Solution Approach 2:
The system uses pneumatic fluidization with pressurized air to disperse powder particles, then introduces this fluidized powder into a pressurized water stream. The pneumatic carrier gas enables uniform particle distribution and prevents clumping during the mixing process.
2Stress or pressure
If eductor systems operate at low pressure, then mixing is possible, but pressure output is limited to 12-13 psi
Solution Approach 1:
The system dynamically adjusts the pressure relationship between air and water streams, maintaining air pressure greater than water pressure throughout the mixing process. This dynamic pressure control enables operation at higher pressures while maintaining effective fluidization and hydration.
Solution Approach 2:
The invention merges the pneumatic fluidization function with the hydraulic mixing function in a single integrated system. The air/powder stream and water stream are combined in the mixing chamber, allowing simultaneous fluidization and hydration at elevated pressures.
3Measurement precision
If conventional Venturi metering is used, then powder introduction is simple, but precision metering is inadequate
Solution Approach 1:
The system incorporates feedback control for the powder metering valve, monitoring and adjusting powder flow rate to maintain precise metering. This feedback mechanism ensures accurate powder introduction rates while compensating for variations in operating conditions.

Function Achieved in This Case
This approach optimizes the hydration of powder particles, preventing clumping and maximizing the fire-retardant properties of the gel, allowing for the production of a more effective fire-retardant gel with improved dispersion and stability.
Implementation Method 1
The powder particles are metered, fluidized within an air stream to disperse the metered particles
Implementation Method 2
the fluidized powder supply is introduced to the pressurized water stream in the mixing chamber to hydrate the powder in the fluidized powder supply therein to form the gel

AI summary
A gel production system and method, in which a powder configured for mixing with an aqueous solvent such as water to form a gel is metered into a pressurized air stream to fluidize the powder, and the fluidized powder is injected into a pressurized water supply. The fluidized powder is at a greater pressure than the water supply, helping to hydrate the fluidized powder in the water, and the water supply plus fluidized powder are subsequently mixed in a mixing chamber to form the gel.
