Cyclonic Filter Array Sections with Dynamic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclonic array filters face performance degradation when deployed in systems with variable or low air flow rates, as the reduced velocities compromise the separation capability of the cyclones, unlike conventional media filters which maintain efficiency regardless of flow rates.
Innovation Solution
The cyclonic array filter is divided into independent sections with dynamically sealable covers that can be opened or closed based on airflow thresholds, ensuring that remaining open sections maintain higher velocities and filtration performance even at reduced overall airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a passive cyclonic array filter is used with high flow rate, then the separation capability is improved, but the filter cannot maintain performance when airflow rate decreases
Solution Approach 1:
The cyclonic array filter is divided into multiple independently sealable sections. Each section can be individually activated or deactivated based on airflow conditions, allowing the filter to adapt to variable airflow rates while maintaining reliable separation performance in each active section.
Solution Approach 2:
The filter incorporates dynamically controllable sealing mechanisms that can open or close sections based on real-time airflow rate detection. This dynamic adjustment allows the filter to maintain optimal separation capability across varying airflow conditions by activating only the necessary number of sections.
2Productivity
If all sections of the cyclonic array are kept open, then the total airflow capacity is increased, but the velocity in each cyclone decreases compromising separation
Solution Approach 1:
Instead of keeping all sections open to maximize airflow capacity, the system activates only the necessary number of sections required to handle the current airflow demand. This partial action maintains high velocity in each active cyclone while achieving sufficient total airflow capacity through selective section activation.
Solution Approach 2:
The system changes the operational parameters by dynamically adjusting the number of active sections based on airflow rate. This parameter change allows the filter to optimize the balance between total airflow capacity and velocity in each cyclone, ensuring effective separation across different operating conditions.
3Reliability
If sections are sealed off to maintain velocity, then the separation capability is maintained, but the number of active sections decreases
Solution Approach 1:
The filter is segmented into multiple independent sections that can be individually activated or deactivated. This segmentation allows the system to seal off unnecessary sections while maintaining separation capability in the remaining active sections, optimizing the balance between reliability and productivity.
Solution Approach 2:
Each section is designed to be universally functional, capable of handling the full range of airflow conditions independently. This multi-functionality allows any section to serve as a backup or primary processing unit, enabling the system to maintain separation capability with fewer active sections when needed.

Function Achieved in This Case
This dynamic sealing mechanism maintains the required filtration efficiency by concentrating airflow into fewer sections, maintaining high velocities within cyclones and thus ensuring effective particle separation despite varying airflow rates.
Implementation Method 1
Upon entering the cavity at a sufficiently high velocity, the air circulates to form a cyclone or a vortex in the cell. The airborne particles experience a centrifugal force that pushes them towards the inner wall of the cavity and are collected at the bottom of the cyclone.
Implementation Method 2
each section is further configured with a cover that can be opened and closed, such that the closing of one or more respective covers of respective sections forces the airstream to flow through remaining sections having open covers as well as their respective cells, at a velocity greater than when such one or more respective covers are open

AI summary
An air filtration system comprising a plurality of sections configured to receive an incoming airstream is disclosed. In some embodiments, each section of the plurality of sections includes a first airstream receiving side (ASRS) and a second air stream exhaust side (ASES), and a plurality of cells each comprising a cyclonic cavity having a tangential inlet arranged to receive a portion of the airstream via the ASRS, and an axial outlet arranged to exhaust the portion of the airstream to the ASES. Each section is further configured with a cover that can be opened and closed, such that the closing of one or more respective covers of respective sections forces the airstream to flow through remaining sections having open covers as well as their respective cells, at a velocity greater than when such one or more respective covers are open.
