Treatment Chamber Gas Recirculation for Energy-Efficient Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatment systems for drying coated vehicle bodies are not energy-efficient, as they often rely on conventional heating methods that waste energy and lack optimized gas circulation systems.
Innovation Solution
A treatment system with a self-contained heating gas duct that recirculates hot gas to efficiently heat the air circulation modules and treatment room sections, using a multi-stage heat exchanger to maximize energy use and a separate fresh gas supply to maintain optimal conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional heating methods are used in treatment systems, then heating function is provided, but energy efficiency is poor and energy waste occurs
Solution Approach 1:
The patent recovers waste heat from exhaust gas through a heat exchanger and reintroduces it into the heating gas duct system. This transforms previously discarded thermal energy into useful heating capacity, directly improving energy efficiency and reducing energy waste in the treatment process
Solution Approach 2:
The heating gas is circulated continuously through a closed-loop duct system that includes treatment room sections and heat exchangers. This continuous circulation ensures sustained heating action without interruption, maintaining optimal drying conditions while improving energy utilization efficiency
2Productivity
If heating gas is supplied to air circulation modules, then drying function is achieved, but energy efficiency decreases without optimized recirculation
Solution Approach 1:
The system implements a feedback mechanism where exhaust gas from treatment rooms is captured, heat-exchanged, and the warmed gas is fed back into the heating gas duct system. This closed-loop feedback ensures that thermal energy is continuously reused, improving energy efficiency while maintaining effective drying function
Solution Approach 2:
The heating gas duct system serves multiple functions: it provides heating to treatment rooms, acts as a heat exchanger medium, and functions as a recirculation pathway for thermal energy. This multi-functionality allows the same gas flow to accomplish multiple objectives, improving overall energy efficiency without compromising drying productivity
