Filter Device Cleaning Through Shared Pressure-Pulse Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter devices require complex and energy-intensive cleaning cycles to remove foreign matter from filter elements, often necessitating separate compressed-air injectors for each clean fluid outlet, which disrupt normal operation.
Innovation Solution
A compressed-air cleaning-off device generates pressure pulses that travel counter to the flow of clean fluid, deflecting at approximately 90 degrees through the clean fluid outlet to clean multiple outlets simultaneously, allowing efficient cleaning without interrupting the filtration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate compressed-air injector is arranged for each clean fluid outlet to inject compressed air directly counter to the flow direction, then cleaning-off effectiveness is improved, but device complexity and energy consumption increase
Solution Approach 1:
A single compressed-air injector serves multiple clean fluid outlets simultaneously by generating pressure pulses that propagate through the common clean fluid collecting channel, eliminating the need for separate injectors at each outlet while maintaining cleaning effectiveness
Solution Approach 2:
Multiple cleaning functions for different outlets are merged into a single integrated system where one injector cleans all outlets through shared fluid dynamics in the collecting channel, reducing overall system complexity
2Reliability
If compressed air is injected directly into the filter element counter to the clean fluid flow, then cleaning-off performance is improved, but energy consumption increases
Solution Approach 1:
The clean fluid collecting channel acts as an intermediary medium that transmits pressure pulses from a single injector to multiple outlets efficiently, reducing the total energy required compared to direct injection at each outlet
Solution Approach 2:
The system utilizes pneumatic pressure pulse propagation through the clean fluid medium to achieve distributed cleaning with centralized energy input, leveraging fluid dynamics to reduce overall energy consumption
3Reliability
If multiple compressed-air injectors are used for each filter element, then cleaning coverage is improved, but the cleaning cycle becomes more complex and time-consuming
Solution Approach 1:
A single injector performs the cleaning function for all filter elements and outlets through the propagating pressure pulses in the common channel, simplifying the cleaning cycle control while maintaining comprehensive coverage
