Galvanization Housing Air Cleaner for Pollutant Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electroplating systems face challenges in thoroughly renewing and cleaning the air inside the housing of transport trolleys, leading to incomplete pollutant removal and potential accumulation, which can result in harmful concentrations and increased energy consumption for ventilation systems.
Innovation Solution
The electroplating system incorporates an air cleaner that continuously cleans the air within the housing using a fan to convey and clean the air using methods such as droplet separators or air washers, allowing for immediate pollutant capture at the source and reducing the need for extensive room air renewal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If room air is blown into the housing and edge suction is intensified to remove pollutants, then pollutant removal is improved, but energy consumption increases and pollutants are discharged into room air
Solution Approach 1:
The invention extracts and removes pollutants directly from the housing interior using a dedicated suction device connected to an exhaust system. This separates the pollutant removal function from the room ventilation system, allowing targeted extraction at the source without the need to blow large volumes of room air into the housing or intensify general edge suction, thereby reducing energy consumption while effectively removing pollutants.
Solution Approach 2:
The invention introduces an intermediary pollutant removal system (housing-specific suction device and exhaust system) between the pollutant source (electroplating bath) and the room air. This intermediary system captures pollutants before they can disperse into the room, eliminating the need for high-energy room air circulation and intensive edge suction while maintaining low pollutant concentrations.
2Object-generated harmful factors
If air exchange in the housing is performed only when the carriage is in a station, then the system is simple, but pollutant removal is incomplete and accumulation occurs
Solution Approach 1:
The invention implements continuous air cleaning by operating the suction device and exhaust system throughout the entire transport cycle, not just when the carriage is stationary at a station. This continuous operation ensures pollutants are constantly removed from the housing interior, preventing accumulation while the system remains relatively simple in design.
Solution Approach 2:
The invention performs preliminary pollutant removal by continuously extracting contaminants as they are generated during transport, rather than waiting until the carriage reaches a station. This preliminary and ongoing action prevents pollutant accumulation throughout the transport process, maintaining air quality without requiring complex intermittent cleaning mechanisms.
3Loss of substance
If the housing is completely closed off at the bottom with drip trays, then liquid containment is improved, but pollutant escape into room air increases during transport
Solution Approach 1:
The invention introduces an intermediary exhaust system that captures pollutants at the source (housing interior) before they can escape through the bottom opening during transport. The suction device creates a controlled airflow that prevents uncontrolled pollutant release, while the drip tray continues to contain liquid effectively. This intermediary system resolves the conflict between liquid containment and pollutant control.
Solution Approach 2:
The invention extracts pollutants from the housing interior through the suction device and exhaust system, removing them before they can escape into the room air through the bottom opening. This extraction mechanism allows the housing to remain effectively closed for liquid containment while simultaneously preventing pollutant escape during transport.
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
This solution enables continuous air cleaning, reducing pollutant concentrations and energy consumption by capturing pollutants as they are released, minimizing their dispersal into the room air and optimizing the transport process by allowing slower transport speeds and reducing the size and energy requirements of ventilation systems.
Implementation Method 1
The enclosure (34) has a fan (48). It is arranged to communicate with an interior space of the enclosure (34) and to transport air from that interior space in a direction to the outside
Implementation Method 2
The air cleaner is adapted to the respective requirements. Different air cleaners are therefore possible with different electroplating bases. Air cleaners or washers are known, for example, from DE 41 39 737 A1, DE 20 2011 051 407 U1, DE 10 2009 030 119 A1, DE 10 2005 025 922 A1, DE 699 30 956 T2, DE 698 29 805 T2.

The baths, in particular the treatment baths, are often provided with a so-called edge suction device. This sucks the air above the surface at high speed into an exhaust system.
