Separator Drum Hood Pressure Reduction via Jet Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing separator arrangements for reducing pressure inside a hood around a drum are complex and costly, requiring additional devices to generate negative pressure, which increases energy consumption and operational complexity.
Innovation Solution
A method and device that utilizes a fluid connection between the hood interior and the distributor space, acting as a jet pump to lower pressure, allowing a liquid or product to be used to reduce hood pressure, eliminating the need for separate pressure reduction devices and simplifying the design without increasing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate device is used to generate negative pressure in the hood interior, then the pressure reduction function is reliable, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the pressure reduction function with the existing liquid delivery system by integrating a fluid connection between the distributor space and hood interior. The liquid serving dual purposes: both product processing medium and jet pump working fluid, eliminating the need for separate pressure reduction devices.
Solution Approach 2:
The liquid delivery system is given multiple functions: it serves as both the product processing medium and the working fluid for pressure reduction. The same liquid that would otherwise be wasted is now utilized to create negative pressure through the jet pump effect.
2Reliability
If a separate device is used to generate negative pressure, then the pressure control is effective, but the energy consumption increases
Solution Approach 1:
The system uses its own liquid flow to generate the negative pressure needed for operation. The liquid that would be discarded is instead utilized to power the jet pump effect, making the system self-sufficient and eliminating external energy input requirements.
Solution Approach 2:
The patent employs hydraulic principles by using liquid flow through a fluid connection to create the jet pump effect. The kinetic energy of the liquid stream directly converts to pressure reduction in the hood interior without requiring mechanical pumps or external power sources.
3Loss of substance
If product is used to reduce pressure before processing, then no product needs to be discarded, but the processing time increases
Solution Approach 1:
The pressure reduction is performed as a preliminary step before actual product processing. By establishing the negative pressure environment first using the liquid jet pump, the system prepares the operating conditions without requiring product presence, then immediately begins productive processing.
Solution Approach 2:
The system changes the operational parameters by using liquid flow rate and pressure to control the jet pump effect. By adjusting these parameters, the system can quickly establish the required negative pressure without prolonged processing times or product waste.
