Buffer Plate Reduces Pressure Fluctuation in Crude Terephthalic Acid Filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pressure filters for Crude Terephthalic Acid experience significant pressure fluctuations during operation, leading to fatigue stress and reduced service life due to the high pressure of the slurry entering the feeding zone.
Innovation Solution
A pressure filter frame with a buffer plate on its inner wall, featuring openings and supporting posts to absorb pressure fluctuations, connected to the shell via welding and flange bases, which reduces pressure transfer to the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pressure filter operates continuously with high pressure slurry feeding, then the filtering productivity is maintained, but the pressure filter frame suffers from continuous pressure fluctuation and fatigue stress
Solution Approach 1:
A buffer plate is introduced as an intermediary component between the feeding zone and the pressure filter frame. The buffer plate absorbs and dampens pressure fluctuations from the high-pressure slurry before they reach the frame, reducing fatigue stress while allowing continuous operation to maintain productivity
Solution Approach 2:
The buffer plate is positioned in advance in the feeding zone to cushion the impact of high-pressure slurry before it reaches the pressure filter frame. This preemptive cushioning reduces pressure fluctuations and protects the frame from fatigue stress during continuous operation
2Object-affected harmful factors
If the buffer plate is positioned close to the feeding zone, then the pressure fluctuation is reduced more effectively, but the device complexity increases
Solution Approach 1:
The buffer plate is divided into multiple segments or sections, each serving specific functions. This segmentation allows the buffer plate to effectively reduce pressure fluctuations while maintaining a relatively simple overall structure that does not significantly increase device complexity
Solution Approach 2:
The buffer plate is strategically positioned only in the feeding zone where pressure fluctuations are most severe, rather than throughout the entire pressure filter. This localized approach effectively reduces pressure fluctuation while minimizing the increase in device complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The buffer plate effectively reduces pressure fluctuations on the filter frame, thereby extending its service life by absorbing some of the pressure impact before it reaches the frame.
Implementation Method 1
a buffer plate is further provided on an inner wall of the pressure filter frame, a plurality of openings are provided in the buffer plate. A gap is remained between the buffer plate and the inner wall of the pressure filter frame
