Spray Pipe Installation for Precise 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 horizontal positioning methods for spray pipes.
Innovation Solution
A method for installing spray pipes that involves a cylindrical pipe with a closed leading end, a leg portion, and an attachment portion, allowing for precise horizontal alignment and secure coupling to the absorption tower using a flange structure and adjustable fastening, which suppresses breakage and deformation.
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 supported against reaction and impactive forces, but the spray pipe may be broken by local forces at contact locations
Solution Approach 1:
The patent applies a flexible bell-shaped rubber cushion at the support contact location to distribute the local force from support rods or straps across a larger area of the spray pipe surface. This flexible element prevents stress concentration that would otherwise cause breakage, while still providing effective support against reaction and impactive forces from the injected liquid absorbent.
2Measurement precision
If the spray pipe is rigidly fixed to prevent movement, then positioning accuracy is improved, but the spray pipe becomes vulnerable to breakage from dynamic forces
Solution Approach 1:
The bell-shaped rubber cushion provides a flexible yet stable support interface that maintains positioning accuracy while absorbing dynamic forces. The flexible material allows for slight movements and vibrations without transmitting damaging stress concentrations to the spray pipe, thereby preventing breakage while preserving positioning precision.
Solution Approach 2:
The rubber cushion acts as a pre-installed protective element that anticipates and absorbs the impact forces from the injected liquid absorbent before these forces can cause damage to the spray pipe. This beforehand cushioning prevents breakage while maintaining the spray pipe's positioned stability.
3Ease of manufacture
If the spray pipe is installed without precise horizontal positioning, then installation is simpler, but accurate positioning is required for effective gas-liquid contact
Solution Approach 1:
The flexible rubber cushion provides a self-aligning support interface that facilitates easier installation while maintaining positioning accuracy. The flexible material allows for minor adjustments during installation and accommodates slight misalignments, making the installation process simpler while still achieving the required horizontal positioning for effective gas-liquid contact.
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
The method enables accurate horizontal positioning and secure attachment of spray pipes, effectively preventing breakage from reaction and impactive forces, ensuring reliable operation and maintenance of desulfurization devices.
Implementation Method 1
a reaction force directed downward is applied to a branch pipe as a liquid absorbent is injected upward
Implementation Method 2
A downward impactive force is also applied to the branch pipe when the upward injected liquid absorbent drops into contact with the branch pipe
