Integration Chamber Mixing Booth and Oven Gas for VOC Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VOC removal systems face inefficiencies due to separate processing of discharge gases from paint spraying booths and baking ovens, which limits energy savings and processing efficiency, as they require separate VOC concentrators and treatment apparatuses.
Innovation Solution
An integration chamber that mixes booth discharge gas and oven discharge gas, followed by a VOC concentrator to increase VOC concentration, and a VOC removing apparatus to treat the combined gas stream, reducing processing loads and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate VOC removing apparatuses are used for paint spraying booth and paint baking oven, then each discharge gas can be treated independently, but the system complexity increases and energy efficiency decreases
Solution Approach 1:
The patent combines two separate VOC treatment systems into a single integrated system. The mixed gas treatment apparatus receives discharge gases from both the paint spraying booth and paint baking oven through a common inlet, and uses one VOC concentrator and one VOC removing apparatus to treat the combined stream, thereby reducing system complexity while maintaining treatment effectiveness
2Reliability
If separate VOC removing apparatuses are used for paint spraying booth and paint baking oven, then each discharge gas can be treated independently, but energy consumption increases
Solution Approach 1:
The patent combines two separate VOC treatment systems into a single integrated system. The mixed gas treatment apparatus receives discharge gases from both the paint spraying booth and paint baking oven through a common inlet, and uses one VOC concentrator and one VOC removing apparatus to treat the combined stream, thereby reducing system complexity while maintaining treatment effectiveness
3Productivity
If a VOC concentrator is used to concentrate discharge gas, then the processing efficiency of VOC removing apparatus is improved and energy consumption is reduced, but the VOC concentrator has temperature sensitivity limitations
Solution Approach 1:
The patent combines the discharge gases from the paint spraying booth and paint baking oven into a single mixed gas stream before entering the VOC concentrator. This mixing allows the system to leverage the temperature characteristics of both gas streams, enabling the VOC concentrator to operate within its optimal temperature range while maintaining high processing efficiency
4Adaptability or versatility
If separate VOC treatment lines are used, then temperature sensitivity of adsorption/desorption element is avoided, but the amount of process gas flowing into VOC removing apparatus increases
Solution Approach 1:
The patent combines the discharge gases from the paint spraying booth and paint baking oven into a single mixed gas stream before entering the VOC concentrator. This mixing allows the system to leverage the temperature characteristics of both gas streams, enabling the VOC concentrator to operate within its optimal temperature range while maintaining high processing efficiency
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
Simultaneous treatment of discharge gases from both sources reduces processing loads and enhances VOC removal efficiency by concentrating oven discharge gases, thereby improving overall system performance.
Implementation Method 1
a mixing portion configured to form a mixture gas by mixing the booth discharge gas and the oven discharge gas
Implementation Method 2
a separating portion configured to separate a liquified VOC from the mixture gas having passed through the mixing portion
Implementation Method 3
a filter portion configured to filter a foreign substance from the mixture gas having passed through the separating portion
Implementation Method 4
the VOC concentrator is provided with an absorption/desorption element such as zeolite, and may concentrate the VOC of the discharge gas by using the VOC adsorption/desorption property

AI summary
A volatile organic compound (VOC) removal system for removing VOC generated during a painting process of a vehicle body includes a paint spraying booth where paint is applied to the vehicle body, a paint baking oven for fixing the paint on the vehicle body applied with the paint in the paint spraying booth, an integration chamber for receiving a booth discharge gas from the paint spraying booth through a booth gas inflow line, to receive an oven discharge gas from the paint baking oven through an oven gas inflow line, and to form a mixture gas by mixing the received booth discharge gas and the received oven discharge gas, a VOC concentrator for forming a process gas by concentrating the mixture gas supplied from the integration chamber to increase a VOC concentration, and a VOC removing apparatus for removing VOC from the process gas supplied from the VOC concentrator.
