Spray Pipe Installation with Adjustable Support for Horizontal Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid column type desulfurization devices face breakage and deformation issues due to reaction and impactive forces from upwardly injected liquid absorbents, and lack accurate positioning methods for spray pipes in the horizontal direction.
Innovation Solution
A method for installing spray pipes that involves provisional tightening, adjustment for horizontal alignment, and final coupling with supporting portions, using a leg portion and attachment flange to securely position the pipe within an absorption tower, allowing for precise horizontal alignment and minimizing stress on the pipe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the spray pipe is supported by contact with support rods or support straps, then the spray pipe is mechanically supported, but the spray pipe may be broken by local forces at contact locations
Solution Approach 1:
The invention transitions from point-contact support (rods and straps) to surface-contact support through the supporting portion's contact surface. By extending the support from a one-dimensional line or zero-dimensional point to a two-dimensional surface, the local force concentration is distributed over a larger area, preventing breakage while maintaining mechanical support.
Solution Approach 2:
The supporting portion is designed with a specific contact surface geometry that matches the spray pipe's outer circumference. This localized adaptation creates an optimized support interface where the contact surface area and shape are tailored to distribute forces evenly, preventing stress concentration at specific points while maintaining overall structural integrity.
2Manufacturing precision
If the spray pipe is firmly fixed to prevent movement, then positioning accuracy is improved, but the spray pipe may break due to reaction and impactive forces from liquid absorbent injection
Solution Approach 1:
The supporting portion allows controlled movement of the spray pipe in the horizontal direction while maintaining vertical support. This dynamic capability enables the system to absorb reaction and impactive forces from liquid absorbent injection without transferring excessive stress to the spray pipe, while still achieving accurate horizontal positioning through the positioning portion.
Solution Approach 2:
The support structure is divided into distinct functional portions: the positioning portion for horizontal alignment and the supporting portion for vertical support with controlled movement. This segmentation allows each portion to optimize its specific function without compromising the other, enabling accurate positioning while preventing breakage from dynamic forces.
3Adaptability or versatility
If the spray pipe is allowed to move horizontally for adjustment, then positioning flexibility is improved, but positioning accuracy deteriorates
Solution Approach 1:
The positioning portion enables preliminary horizontal adjustment of the spray pipe before final fixation. This preliminary action allows operators to achieve accurate positioning through adjustment mechanisms, after which the structure can be secured to maintain that position, thus combining flexibility during installation with precision in the final configuration.
