Diverter Device for Pulse Jet Filter Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pulse jet cleaning systems require multiple control valves to efficiently clean filters, leading to increased complexity and potential inefficiencies, as each control valve typically serves two filters, which can result in shortened filter life if dust cake is not removed effectively.
Innovation Solution
A diverter device is introduced that receives pulse air from a control valve and diverts it into multiple outlet ports to clean multiple blowpipes, reducing the number of control valves needed by allowing a single control valve to serve multiple filter assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple control valves are used to clean multiple filters, then cleaning effectiveness is improved, but system complexity and cost increase
Solution Approach 1:
The pulse air flow is segmented into multiple separate pulses, with each pulse directed to a different filter assembly through the diverter device. This allows a single control valve to effectively clean multiple filters by dividing the compressed air supply into discrete streams, resolving the contradiction between using multiple valves and system simplicity.
Solution Approach 2:
The diverter device acts as an intermediary component between the single control valve and multiple filter assemblies. It receives the pulse air from the control valve and distributes it to the appropriate blowpipes serving different filters, eliminating the need for multiple control valves while maintaining effective cleaning of all filter assemblies.
2Device complexity
If a single control valve serves multiple filters, then system complexity is reduced, but cleaning effectiveness may deteriorate
Solution Approach 1:
The diverter device segments the single pulse air supply into multiple distinct pulses, ensuring each filter assembly receives adequate cleaning attention. This segmentation maintains cleaning effectiveness despite using fewer control valves.
Solution Approach 2:
The system uses periodic pulsing of compressed air through the diverter device to sequentially clean multiple filter assemblies. Each filter receives periodic cleaning pulses, ensuring effective dust removal while using a single control valve.
3Productivity
If more control valves are installed, then more filters can be cleaned simultaneously, but maintenance requirements and service needs increase
Solution Approach 1:
The diverter device merges the functions of multiple control valves into a single integrated component. By combining the pulse distribution function into one device, the system reduces the total number of valves that require maintenance while maintaining the capability to clean multiple filters.
Solution Approach 2:
The diverter device performs multiple functions that would traditionally require separate control valves. It distributes pulse air to multiple blowpipes serving different filter assemblies, making a single component multi-functional and reducing overall system complexity and maintenance needs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the number of control valves required, simplifies the system, and ensures consistent pressure delivery for effective dust removal, thereby extending filter life and improving cleaning efficiency.
Implementation Method 1
a pulse or pulses of compressed air hit or shock the filter media and knock the cake off
Implementation Method 2
The pulse valve sends a given volume of air to the filter at a predetermined velocity to strike and clear the cake. The actual amount of air is dependent upon the pulse nozzle being fed compressed air at a predetermined and fixed pressure.
