Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cleaning hard surfaces and soil of oil and petroleum products are inefficient, leading to high reagent consumption and low oil removal efficiency, with the inability to recycle removed oils and surface-active materials, posing ecological safety concerns.
Innovation Solution
A water solution of natural polysaccharide microgels and surface-active agents with a concentration of at least 0.2 g/l, where the ratio of polysaccharide microgels to surface-active agents ranges from 10:1 to 1:10, is used to treat surfaces, allowing for improved oil removal and recycling of both oils and surface-active agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional cleaning methods (surface-active compounds, oxidizing agents, alkalis, steam treatment, surface burning) are used to clean hard surfaces or soil of oil, then oil removal is achieved, but toxic residues are produced that are hazardous to the environment
Solution Approach 1:
The patent changes the chemical composition parameters of the cleaning agent by using polysaccharide microgels with specific molecular mass (20,000-200,000 Da) and particle size (50-600 nm) at controlled concentrations (0.1-20 g/l), replacing traditional toxic cleaners with biodegradable polysaccharide-based substances that maintain cleaning effectiveness while eliminating toxic residues
Solution Approach 2:
The patent employs polysaccharide microgels that facilitate enhanced oxidation of oil contaminants through their unique gel structure and high surface area, enabling efficient oil breakdown and removal without requiring strong chemical oxidants that leave toxic residues
2Productivity
If conventional cleaning substances are used, then cleaning action is provided, but reagent consumption is high and oil removal efficiency is low
Solution Approach 1:
The patent utilizes polysaccharide microgels with a porous gel structure that provides high surface area and multiple active sites for oil adsorption and emulsification, enabling efficient oil removal at low reagent concentrations (0.1-20 g/l) and reducing overall reagent consumption
Solution Approach 2:
The patent creates a composite cleaning system by combining polysaccharide microgels with specific concentrations of auxiliary substances, forming a synergistic formulation that enhances oil removal efficiency while minimizing the quantity of each component needed
3Productivity
If traditional cleaning approaches are used, then oil is removed from surfaces, but the removed oils and surface-active materials cannot be recycled
Solution Approach 1:
The patent enables recovery and recycling of both the polysaccharide microgel cleaning agent and the removed oil contaminants through separation processes, transforming the linear cleaning process into a circular system where materials are recovered and reused, reducing waste and operational costs
