Compressed Air Pulse Device for Filter Rinsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for generating compressed air pulses to flush filter units, particularly those located below water surfaces, are inefficient and unreliable when there is a significant distance between the compressed air source and the point of application.
Innovation Solution
A device that utilizes a compressed air tank filled via a supply line from a remote compressor, where the stored compressed air both generates the pulse and drives the outlet valve, allowing for efficient and compact operation, even at distances up to 1 km from the air source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a compressed air tank is filled via a supply line from a remote compressor, then the device can operate at distances up to 1 km from the air source, but the filling time becomes excessively long
Solution Approach 1:
The compressed air tank is pre-filled with compressed air through a supply line from a remote compressor before the actual pulse generation is needed. This preliminary action ensures that when the compressed air pulse is required, the tank is already ready to deliver the pulse immediately, eliminating delays associated with on-demand compression over long distances.
Solution Approach 2:
The compressed air tank serves as an intermediary energy storage device between the remote compressor and the pulse generation point. It decouples the compression process from the pulse delivery process, allowing the compressor to operate remotely and fill the tank at its own pace, while the tank holds the compressed air ready for rapid deployment when needed.
2Device complexity
If the compressed air tank uses stored air to drive the pneumatic outlet valve, then the device structure becomes compact and efficient, but the air pressure must be precisely controlled to ensure reliable valve actuation
Solution Approach 1:
The compressed air stored in the tank serves multiple functions simultaneously: it provides the main compressed air pulse for flushing the filter unit and also drives the pneumatic outlet valve to control the release of the pulse. This multi-functionality eliminates the need for separate air sources or complex control mechanisms, simplifying the overall device structure while maintaining reliability through proper pressure management.
