Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing desulfurization devices face difficulties in easily replacing or inspecting spray pipes due to complex welding or caulking processes, leading to prolonged work times and complications when damage or clogging occurs.
Innovation Solution
A desulfurization device design featuring a spray pipe with a closed leading end and detachable flange portions that attach to corresponding flange portions around the absorption tower's opening holes, allowing for easy removal and installation of the spray pipe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spray pipe is fixed to the absorption tower by welding or caulking material, then the sealing performance is improved, but the ease of repair deteriorates
Solution Approach 1:
The spray pipe is divided into a pipe body and a flange portion that are detachably connected. The flange portion is separated from the pipe body and can be independently attached to the absorption tower, allowing the spray pipe to be segmented into removable components for easy maintenance while maintaining secure connection during operation.
Solution Approach 2:
The flange portion is provided with a local sealing structure that concentrates the sealing function at the connection interface between the flange and the absorption tower opening hole. This localized sealing design ensures reliable sealing performance at the critical connection point while allowing the rest of the spray pipe to be easily removable.
2Reliability
If the spray pipe is accurately installed in the absorption tower, then the desulfurization performance is improved, but the device complexity increases
Solution Approach 1:
The flange portion is pre-provided with positioning structures and connection holes that guide the alignment and attachment process. The opening hole in the absorption tower is also pre-configured with corresponding positioning features, enabling accurate installation without requiring complex adjustment procedures during the installation process.
Solution Approach 2:
The flange portion acts as an intermediary component between the spray pipe body and the absorption tower. It provides a standardized connection interface that simplifies the attachment process while ensuring accurate positioning and secure connection, thereby reducing installation complexity without compromising installation precision.
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
Facilitates quick and accurate replacement and inspection of spray pipes, reducing work time and preventing damage during installation by ensuring proper alignment and minimizing contact with the opening hole.
Implementation Method 1
a chemical reaction between a combustion exhaust gas and the liquid absorbent causes sulfur oxide in the combustion exhaust gas to be removed
Implementation Method 2
A downward impactive force is also applied to the spray pipe when the upward injected liquid absorbent drops into contact with the spray pipe
