Particle Removal Filter Cleaning via Bypass Wet Wash
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing particle discharge devices require filter removal for cleaning, which is cumbersome and costly, necessitating the use of lifting columns.
Innovation Solution
A particle discharge device with a bypass channel and shut-off valve allows in-place cleaning (CIP) without filter removal, featuring a clean gas chamber cleaning nozzle and process chamber cleaning nozzle for wet cleaning, and a dry cleaning mechanism for automated filter maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If filter removal is used for cleaning, then cleaning can be performed, but device complexity increases due to lifting column requirement
Solution Approach 1:
The system performs self-cleaning through automated spray nozzles that clean the filter element in place, eliminating the need for manual removal and lifting column infrastructure. The clean gas chamber cleaning device and process chamber cleaning device enable the system to maintain itself without external intervention or complex support structures.
Solution Approach 2:
Hydraulic spray nozzles deliver cleaning fluid to the filter element through the bypass channel, enabling in-place cleaning without mechanical removal. The use of fluid delivery systems replaces the need for lifting mechanisms and manual handling infrastructure.
2Ease of manufacture
If filter removal is used for cleaning, then cleaning can be performed, but loss of time increases due to removal and reinstallation
Solution Approach 1:
The cleaning operation is integrated into the continuous operation of the particle discharge device. The bypass channel allows cleaning fluid to be delivered during normal operation or quick maintenance cycles, eliminating the need to stop the system for filter removal and reinstallation. The automated system maintains continuous or near-continuous operation.
Solution Approach 2:
The spray nozzles are pre-positioned to deliver cleaning fluid directly to the filter element at the optimal locations. The bypass channel is pre-configured to route cleaning fluid efficiently, allowing immediate cleaning action without the time-consuming steps of filter removal and reinstallation.
3Ease of manufacture
If filter removal is used for cleaning, then cleaning can be performed, but ease of operation worsens due to manual handling requirements
Solution Approach 1:
The system automates the cleaning function through spray nozzles and fluid delivery systems, eliminating manual filter handling. The bypass channel and shut-off valve enable automated control of the cleaning process without operator intervention for filter removal or installation.
Solution Approach 2:
Manual mechanical filter handling is replaced by an automated fluid delivery system. The bypass channel with shut-off valve provides automated control mechanisms that substitute for manual operation, improving ease of operation through automation.
