Solution Overview
Problem
Industrial processes face challenges with the formation of organic and inorganic precipitations on the walls of flow pipes and reactors, leading to product quality issues, production interruptions, and increased maintenance costs, as existing methods fail to completely prevent these precipitations from forming and adhering to surfaces.
Innovation Solution
A reactor system that uses electric or magnetic fields to prevent chemicals and their reaction products from adhering to the surface, incorporating injection mixers for efficient mixing and a cleaning system that maintains the reactor surface by controlling pH levels and using materials that precipitates do not adhere to, allowing for a shorter reactor design and reduced material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If chemicals are introduced into process liquid flow to form precipitations or accumulations on pipe walls, then the desired chemical reaction or process function is achieved, but precipitations accumulate on the wall surface causing product quality deterioration, process interruptions, and increased maintenance costs
Solution Approach 1:
The patent applies electric or magnetic fields to prevent precipitations from adhering to pipe walls, converting the potentially harmful accumulation effect into a beneficial cleaning action. The fields create repulsive forces that keep precipitates suspended in the flow, allowing the chemical reaction to proceed efficiently while preventing wall accumulation that would otherwise cause product quality issues and maintenance interruptions
Solution Approach 2:
The patent changes physical parameters by introducing electric or magnetic fields into the chemical process system. These fields modify the behavior of precipitating particles, preventing them from adhering to pipe walls. This parameter change allows the system to maintain high chemical reaction efficiency while eliminating the harmful effect of precipitation accumulation on surfaces
2Ease of operation
If conventional mixing methods are used to introduce chemicals into process flow, then chemicals are mixed with the flowing material, but precipitations still form and adhere to reactor surfaces requiring frequent cleaning and maintenance
Solution Approach 1:
The patent converts the harmful adhesion of precipitates to reactor surfaces into a beneficial effect by applying electric or magnetic fields that create repulsive forces. This prevents precipitates from sticking to walls, reducing cleaning frequency and maintenance requirements while maintaining effective chemical mixing through the same flow conditions
Solution Approach 2:
The reactor system becomes self-cleaning through the application of electric or magnetic fields that continuously prevent precipitate adhesion to surfaces. The fields are activated during operation to maintain clean reactor walls without requiring external cleaning interventions, thereby reducing maintenance time and operational interruptions
3Device complexity
If chemicals are introduced directly into process pipes without specialized mixing equipment, then the system remains simple, but precipitations accumulate on pipe walls causing blockages and process disruptions
Solution Approach 1:
The patent applies electric or magnetic fields within the existing pipe system to prevent precipitate accumulation, converting a simple chemical injection system into a reliable process that maintains continuous operation. The fields prevent blockages and process disruptions without requiring complex mechanical mixing equipment, thereby maintaining system simplicity while improving reliability
Solution Approach 2:
The patent introduces electric or magnetic field parameters into the chemical process system to prevent precipitation adhesion to pipe walls. This parameter change enables direct chemical introduction into process pipes without specialized mixing equipment, maintaining system simplicity while preventing blockages and ensuring continuous reliable operation
