Integrated Gas Downcomer Pipe Mounting to Suppress Deposits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-pipe type gas-liquid contact devices and support structures require multiple components for installation, leading to complex operations and deposit accumulation issues during use.
Innovation Solution
A gas downcomer pipe and installation member with a integrated pipe-shaped and protruding part design that simplifies installation into a partition wall, using a single member to reduce manufacturing costs and prevent deposit accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple components (head sections and collar sections) are used for installing pipes into partition walls, then the pipes can be replaced without damaging the tank main body, but the number of operating steps increases and operating time is reduced
Solution Approach 1:
The patent combines the head section and collar section into a single integrated installation member. This installation member includes a pipe-shaped portion that fits over the pipe and a collar portion that interfaces with the partition wall opening, eliminating the need for separate components and reducing installation steps while maintaining the ability to replace pipes without damaging the tank main body
2Strength
If multiple components (support members and anchor members) are used for supporting and anchoring pipes, then the pipes can be securely installed, but the structure becomes complicated and deposits adhere to recesses and gaps
Solution Approach 1:
The patent integrates the support function and anchoring function into a single collar portion of the installation member. The collar portion has an outer surface that contacts the partition wall opening and provides both support and anchoring capabilities, eliminating the need for separate support members and anchor members, thereby simplifying the structure while maintaining secure pipe installation
Solution Approach 2:
The installation member is designed with specific local features: the pipe-shaped portion has an inner surface that contacts the pipe outer surface for support, while the collar portion has an outer surface that contacts the partition wall opening for anchoring. These localized contact surfaces provide the necessary strength without requiring complex multi-component structures

AI summary
There are provided a downcomer pipe that can achieve suppression of accumulation of deposits in use and simplification of operation when being installed into a partition wall, an installation member and a desulfurization apparatus. The downcomer pipe comprises a pipe-shaped member and an installation member for installing the pipe-shaped member into the partition wall. The installation member includes a pipe-shaped part whose inner wall is to be brought into contact with the outer wall of the pipe-shaped member and a protruding part arranged on the outer wall of the pipe-shaped part, the pipe-shaped part and the protruding part constituting an integrated member.
