Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste compactor systems are inefficient in disposing of liquid waste, relying on energy-intensive evaporation methods that do not effectively reduce waste volume and weight, and are not suitable for treating industrial and municipal solid waste containing plastics or materials with high melting points.
Innovation Solution
A waste compactor vehicle equipped with a compaction chamber, liquid collection system, and evaporation system that uses a filter unit to separate liquid and solid waste, and an evaporation system utilizing exhaust gas heat to efficiently evaporate liquid waste, reducing waste volume and weight while minimizing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional evaporation methods are used to dispose of liquid waste, then liquid waste can be removed, but energy consumption is excessive
Solution Approach 1:
The patent converts the harmful exhaust heat from the vehicle engine into a beneficial resource for evaporating liquid waste. The exhaust gas, which would otherwise be wasted, is directed through a heat exchanger to provide the thermal energy needed for evaporation, thereby turning a harmful byproduct into a useful heating source and significantly reducing additional energy requirements.
Solution Approach 2:
The system uses the vehicle's own exhaust heat to evaporate its own liquid waste, making the waste treatment process self-sufficient. The exhaust heat exchanger is integrated into the vehicle's existing thermal management system, allowing the vehicle to treat its own waste without requiring external energy inputs or separate heating systems.
2Productivity
If high temperature heating is used to evaporate liquid waste, then evaporation efficiency is improved, but plastics and materials with high melting points are damaged
Solution Approach 1:
The patent changes the temperature parameter of the heating process by using exhaust gas instead of high-temperature direct heating. The exhaust gas provides moderate thermal energy that is sufficient for evaporation but does not exceed the melting points of plastics and other sensitive materials, thereby maintaining evaporation efficiency while preventing material damage through controlled temperature application.
