Static Elimination Valve for Organic Solvent Pipelines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for delivering organic solvents through pipelines face risks of static electricity accumulation, which can lead to breakdown, spark, ignition, or explosion due to friction, and conventional solutions like stainless steel pipes conduct triboelectricity while non-conductive Teflon pipes fail to eliminate static electricity effectively.
Innovation Solution
An inner static electricity eliminating control valve design featuring a pneumatic valve, check valve, static electricity export mechanism, and solvent export portion that periodically applies pressure to the solvent, allowing it to flow through a check valve and export static electricity via a metal static electricity export head connected to a grounding wire, effectively neutralizing static electricity within the pipeline.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stainless steel pipes are used to deliver organic solvent, then static electricity is conducted away, but chemical reactions occur between the solvent and pipe material causing qualitative change
Solution Approach 1:
The delivery system is segmented into distinct functional zones: a reaction-resistant pipe section (PTFE) for chemical compatibility, and a separate static electricity elimination system using conductive elements (metal mesh or wire) that do not contact the solvent directly but eliminate static through the pipe wall or dedicated elimination sections
Solution Approach 2:
A conductive intermediary element (metal mesh, wire, or conductive coating) is introduced as a mediator between the non-conductive PTFE pipe and the ground. This intermediary eliminates static electricity without requiring direct contact between the solvent and conductive materials, thus preventing chemical reactions while maintaining static elimination functionality
2Stability of the object's composition
If Teflon pipes are used to deliver organic solvent, then chemical reactions are prevented, but static electricity accumulates leading to breakdown, spark, ignition or explosion risks
Solution Approach 1:
A conductive intermediary element (metal mesh, wire, or conductive coating) is introduced as a mediator between the non-conductive PTFE pipe and the ground. This intermediary eliminates static electricity without requiring direct contact between the solvent and conductive materials, thus preventing chemical reactions while maintaining static elimination functionality
Solution Approach 2:
The PTFE pipe system is enhanced with multi-functionality by integrating static elimination capabilities through conductive elements that serve dual purposes: eliminating static electricity while maintaining the pipe's chemical resistance and solvent compatibility
3Reliability
If a control valve is added to eliminate static electricity, then static electricity is removed, but device complexity increases
Solution Approach 1:
The static electricity elimination function is merged with the existing control valve structure. Conductive elements (metal mesh, wire, or conductive coating) are integrated into the valve body or flow path, combining flow control and static elimination into a single component rather than adding separate systems
Solution Approach 2:
The control valve is enhanced with multi-functionality by incorporating static elimination capabilities into its existing structure, allowing it to perform both flow control and static electricity elimination functions simultaneously
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 solution effectively eliminates inner static electricity in organic solvent delivery pipelines, reducing the risk of hazards such as breakdown, spark, or explosion by periodically exporting static electricity to the ground, while maintaining controlled solvent flow and preventing excessive solvent loss.
Implementation Method 1
a metal static electricity export head (71) configured inside the subsidiary valve chamber (50) and a static electricity conduction wire (72) connected to the metal static electricity export head (71) and extending out of the valve casing (20)
Implementation Method 2
the pneumatic valve can periodically apply a pressure toward the organic solvent inside the main valve chamber, so that the organic solvent inside the main valve chamber can be periodically delivered through the check valve to the subsidiary valve chamber
Implementation Method 3
a large amount of static electricity will be generated due to friction during the flow of organic solvent inside the delivery pipeline
