Air Purification Plant Filter Pocket Cleaning via Multidimensional Nozzle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air purification plants in the textile industry face challenges with complex construction, high space requirements, and inefficient filter cleaning due to electrostatic fiber accumulation and poor accessibility, leading to reduced filtration capacity and increased susceptibility to failure.
Innovation Solution
An air purification plant design featuring a partition wall with filter boxes forming vertical filter pockets, allowing for efficient air filtration and cleaning using a single suction nozzle that moves in two spatial dimensions, eliminating the need for additional space and enabling continuous operation during cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suction device is used to clean filter faces, then filtration performance is maintained, but fiber accumulation blocks the suction nozzle
Solution Approach 1:
The suction nozzle is moved not only vertically but also horizontally along the filter pocket, allowing it to access areas behind and around the filter wall where fibers accumulate. This multidimensional movement enables the suction nozzle to reach previously inaccessible cleaning zones, preventing blockages while maintaining filtration performance.
2Ease of operation
If multiple suction elements are used to clean all filter niches, then cleaning coverage is improved, but device complexity and space requirements increase
Solution Approach 1:
A single suction nozzle is designed to perform multiple functions by moving both vertically and horizontally. It can clean the front filter surface, reach behind the filter wall through horizontal movement, and service multiple filter pockets sequentially. This multi-functional design eliminates the need for multiple dedicated suction elements, reducing device complexity while maintaining comprehensive cleaning coverage.
3Strength
If filter pockets are closed at the bottom, then structural integrity is improved, but accessibility for cleaning is reduced
Solution Approach 1:
The suction nozzle is designed with dynamic movement capabilities in both vertical and horizontal directions. This dynamic positioning allows the nozzle to access the bottom area of filter pockets through horizontal movement along the filter pocket, even when the bottom is structurally closed. The dynamic movement compensates for the closed structure, maintaining both structural integrity and cleaning accessibility.

AI summary
An air purification plant, having a partition wall for the spatial separation of a dirty-air space, which is disposed upstream, from a clean-air space, which is disposed downstream, which partition wall has a support frame and a plurality of filter boxes which project from the support frame in the direction of the dirty-air space, and the filter boxes have at least one filter wall which extends from the support frame into the dirty-air space. The filter boxes are in each case open only in the clean-air space which is disposed downstream, wherein filter walls, which face one another, of adjacent filter boxes in each case form a filter pocket which is open on the upstream side and at the bottom, and for switching from one filter pocket into an adjacent filter pocket a suction nozzle is moved through below the filter box which separates the two filter pockets.
