Pulse Jet Air Cleaner With Accumulator And Flexible Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air cleaner systems with pulse jet technology face challenges in effectively extending the service life of filter cartridges and maintaining equipment operation due to inefficiencies in dust evacuation and filtration, particularly in heavy-duty applications like mining equipment.
Innovation Solution
A pulse jet air cleaner assembly with a housing featuring a separate compressed gas accumulator tank and a serviceable filter cartridge, utilizing a pulse jet cleaning arrangement to direct compressed gas through the filter cartridge in an in-to-out flow pattern, accompanied by an evacuation valve arrangement for selective dust removal, and a flexible valve member that flexes to allow dust ejection during pulses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pulse jet cleaning arrangement directs compressed gas through filter cartridge, then dust evacuation effectiveness is improved, but device complexity increases due to separate accumulator tank and evacuation valve arrangement
Solution Approach 1:
The air cleaner assembly is divided into functionally independent sections: a filter cartridge receiving section and a separate compressed gas accumulator tank section. This segmentation allows each component to be optimized independently while maintaining overall system effectiveness for dust evacuation.
Solution Approach 2:
An evacuation valve arrangement acts as an intermediary component between the filter cartridge and the external environment. This valve selectively controls dust ejection during pulse jet operation, enabling effective dust removal without requiring complex integrated systems.
2Ease of repair
If serviceable filter cartridge with open interior is used, then ease of repair is improved, but manufacturing precision requirements increase for the media pack structure
Solution Approach 1:
The filter cartridge is designed as a serviceable component with a media pack surrounding an open interior, allowing the filter element to be removed, cleaned, or replaced independently from the housing. This segmentation enables easy maintenance while the media pack structure maintains sufficient manufacturing precision for effective filtration.
Solution Approach 2:
The filter cartridge is designed to be serviceable by the user, allowing easy removal and replacement of the media pack. This self-service capability extends equipment operational life and reduces maintenance costs without requiring specialized service facilities.
3Productivity
If flexible valve member is used to allow dust ejection, then productivity is improved through extended filter life, but reliability may worsen due to flexible component wear
Solution Approach 1:
The flexible valve member operates periodically during pulse jet cleaning cycles, flexing to allow dust ejection and then returning to its sealed position. This periodic operation extends filter cartridge service life by enabling repeated cleaning cycles, thereby improving overall system productivity.
Solution Approach 2:
A flexible valve member is used to control dust ejection during pulse jet operation. The flexibility of this component allows it to respond dynamically to pressure changes while maintaining a reliable seal during normal operation, balancing productivity gains with component durability.
