Integrated Selecting Device for Thermal Plant Cleaning Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning apparatuses for thermal and hydraulic plants are complex to use, particularly in connecting and managing the flow of cleaning fluids, often leading to leaks and increased operational complexity due to the need for frequent disconnection and reconnection of ducts to reverse fluid flow.
Innovation Solution
A compact apparatus with a selecting device and obstruction elements controlled by levers, allowing for reversible flow of washing, descaling, and rinsing liquids without disconnection, utilizing a pump, tank, and strategically positioned chambers and conduits for efficient fluid management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple valves and diverters connected with common hydraulic fittings are used to manage cleaning fluid flow, then flow direction control is achieved, but device complexity and risk of leaks increase
Solution Approach 1:
The patent combines multiple flow control functions (valves, diverters, flow direction management) into a single integrated selecting device with multiple chambers and conduits. This merging eliminates the need for separate valves and hydraulic fittings, reducing device complexity while maintaining flow control capability.
Solution Approach 2:
The selecting device serves multiple functions simultaneously: it acts as a flow distributor, direction controller, and connection manifold all in one component. This multi-functionality replaces what would traditionally require multiple separate components, simplifying the overall system.
2Ease of operation
If ducts are disconnected and reconnected to reverse cleaning fluid flow, then flow direction is changed, but ease of operation decreases and time is lost
Solution Approach 1:
The selecting device incorporates movable septa that can be dynamically repositioned to change flow direction without any disconnection. The lever mechanism allows dynamic switching between different flow paths, enabling quick flow reversal while maintaining continuous physical connections.
Solution Approach 2:
The movable septa act as intermediaries that redirect flow internally within the selecting device. Instead of requiring external disconnection and reconnection, the septa mediate the flow direction change by blocking certain passages and opening others, achieving flow reversal quickly and conveniently.
3Ease of operation
If auxiliary frames with valves and diverters are used, then flow management is achieved, but ease of manufacture and maintenance decrease
Solution Approach 1:
By integrating all flow management functions into a single selecting device with standardized housing and components, the patent simplifies manufacturing compared to assembling multiple separate valves and diverters on auxiliary frames. The unified structure reduces part count and assembly complexity.
Solution Approach 2:
The patent employs standardized sealing surfaces and gasket configurations that simplify manufacturing and replacement. The consistent design of connection interfaces and sealing elements across the selecting device enables easier fabrication and maintenance compared to custom-fitted auxiliary frame assemblies.
