Purification system having pipelines arranged at different levels in height direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air separation purification systems require large site spaces due to horizontal arrangement of pipelines, leading to increased energy consumption and costs, especially in compact locations.
Innovation Solution
The pipelines are arranged at different heights, with a three-stem valve platform framework structure facilitating overhaul, reducing the ground space required and allowing for more efficient use of space above the valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pipelines are arranged horizontally in parallel, then ease of operation is improved, but area of stationary object increases
Solution Approach 1:
The patent transitions from horizontal parallel arrangement to vertical stacking arrangement of pipelines at different heights. The air input pipeline, air output pipeline, and waste nitrogen input pipeline are arranged at different elevation levels, utilizing the vertical dimension to reduce ground space occupation while maintaining operational accessibility through platform frameworks.
2Area of stationary object
If pipelines are arranged at different heights, then area of stationary object is reduced, but device complexity increases
Solution Approach 1:
The patent divides the pipeline system into distinct vertical segments at different height levels. Each pipeline (air input, air output, waste nitrogen input) is positioned at a specific elevation, creating modular segments that can be independently installed and maintained. The three-stem valve platform framework is also segmented into multiple levels corresponding to different pipeline heights.
Solution Approach 2:
The patent introduces three-stem valve platform frameworks as intermediary structures to support and organize pipelines at different heights. These platforms serve as mediating elements that facilitate valve installation, operation, and maintenance while coordinating the spatial relationships between pipelines at various elevation levels.
3Ease of repair
If mobile crane is used for valve overhaul, then ease of repair is improved, but area of stationary object increases
Solution Approach 1:
The patent enables self-service repair capabilities by installing platform frameworks at different heights that provide direct access to three-stem valves. Maintenance personnel can perform valve overhauls directly on the platforms without requiring external mobile crane equipment, making the system self-sufficient for routine maintenance operations.
Solution Approach 2:
The patent incorporates platform frameworks and hoisting devices in advance during system installation. These preliminary structural preparations enable future maintenance operations to be performed without requiring additional heavy equipment, as the infrastructure for valve access and replacement is already in place at the correct heights.
