Electrostatic Precipitator Frame with Retainer Devices for Front-Loading Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrostatic precipitators lack a frame that forms an integral unit, retainer devices to hold the frame in a chassis, and are not front-loadable, which limits their installation and maintenance.
Innovation Solution
A frame for an electrostatic precipitator cell with side portions, an open top and bottom, support projections, a handle, and retainer devices that engage the air cleaner chassis, allowing for easy assembly, suspension, and secure attachment within the air cleaner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrostatic precipitator is assembled by inserting electrode plates into a chassis or welding/bonding plates into a fixed unit, then the structure can be formed, but there are no retainer devices to hold the frame into the chassis and the electrostatic precipitator cannot be front-loaded for easy maintenance
Solution Approach 1:
The frame is divided into multiple portions (first frame portion, second frame portion, etc.) that can be separately manufactured and then assembled together. This segmentation allows each portion to be optimized independently and enables the frame to be disassembled for front-loading maintenance while maintaining structural integrity when assembled.
Solution Approach 2:
The frame transitions from a fixed, permanent structure to a dynamic, removable structure. The frame portions can be assembled and disassembled, allowing the electrostatic precipitator to be front-loaded for maintenance and then reassembled, providing operational flexibility without compromising structural stability during operation.
2Ease of operation
If the electrostatic precipitator rests in the chassis on its bottom surface, then it can be held in place, but it cannot be front-loaded and requires disassembly for maintenance
Solution Approach 1:
Retainer devices are pre-formed on the frame portions before assembly. These retainer devices are designed to engage with the chassis in a predetermined manner, ensuring secure attachment is established before the electrostatic precipitator is installed in the chassis, allowing for reliable front-loading without requiring disassembly.
3Reliability
If the frame includes retainer devices to engage the air cleaner chassis, then secure attachment is achieved, but the frame structure becomes more complex
Solution Approach 1:
The retainer devices are merged with the frame portions, forming an integrated structure where the retainers are built into the frame rather than being separate components. This merging provides secure attachment to the chassis while minimizing additional complexity, as the retainers are formed as part of the frame assembly process.

AI summary
A frame for an electrostatic precipitator cell is provided according to an embodiment of the invention. The frame in one embodiment includes a first frame portion adapted to at least partially receive the electrostatic precipitator cell and a second frame portion adapted to at least partially receive the electrostatic precipitator cell. The second frame portion assembles to the first frame portion to form the frame. The frame includes one or more side portions, an open top end, and an open bottom end. The frame receives and holds the electrostatic precipitator cell.
