Solution Overview
Problem
Existing air treatment devices for surface treatment systems, such as painting systems, face challenges in achieving effective cleaning and humidification while avoiding interference from multiple air inlets and maintaining suitable environmental conditions for water-based paints, particularly in terms of relative humidity and germ removal.
Innovation Solution
The device introduces the supply air flow directly into a water bath within the air cleaning chamber, where it flows through and is heated, allowing for improved cleaning and humidification, with fresh air supplied to enhance moisture absorption and germ removal, and includes features like UV light for sterilization and adjustable temperature and humidity settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple air inlets (supply air and fresh air) are provided above the water level to improve cleaning effect, then air cleaning performance is improved, but mutual interference between pressurized air streams occurs causing operational problems
Solution Approach 1:
Instead of introducing air streams above the water level as in conventional designs, the invention inverts the approach by introducing the supply air stream below the water level. This reversal eliminates the mutual interference problem while maintaining effective cleaning through the water bath.
2Manufacturing precision
If supply air is introduced above the water level to improve cleaning, then particle removal is enhanced, but humidification effect is reduced
Solution Approach 1:
The invention reverses the conventional approach by introducing air below the water level, which allows the air stream to be effectively humidified as it passes through the water bath, while still achieving particle removal through the water contact.
3Manufacturing precision
If fresh air and supply air are supplied through separate pressurized inlets above water level, then cleaning effectiveness is improved, but system complexity and interference increase
Solution Approach 1:
The invention combines the functions of fresh air supply and supply air introduction into a single inlet system below the water level. This merging eliminates the complexity and mutual interference associated with multiple separate pressurized inlets while maintaining effective air cleaning and humidification.
4Reliability
If air is cleaned and humidified effectively, then suitable environmental conditions for water-based paint are created, but energy consumption increases
Solution Approach 1:
The water bath serves multiple functions simultaneously: it cleans particles from the air stream, humidifies the air, and acts as a heat exchange medium. This self-service approach reduces the need for separate heating and humidification systems, thereby lowering overall energy consumption while ensuring suitable conditions for water-based painting.
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 approach results in a cleaner, more humidified air flow that is almost free of dust and germs, suitable for hygienic environments, and allows for precise control of atmospheric conditions, reducing energy consumption and preventing paint surface issues like skin formation and cracking.
Implementation Method 1
As it flows through the water bath, the incoming air flow that is introduced also already absorbs moisture
Implementation Method 2
in an upper area of the air cleaning chamber in the area of the air outlet there is a downstream heating register for heating the exhaust air flow
Implementation Method 3
In the medical field, a UV light source is preferably provided for irradiating the water bath in the air cleaning chamber. In this way, germs can be killed in the water bath and the air flow can be sterilized.

AI summary
A device (1) for air treatment, in particular for a surface treatment plant, such as a painting plant, comprises an air cleaning chamber (2) containing a water bath (W) and having at least one air inlet (8) for supplying an incoming air stream and an air outlet (15) for removing a cleaned air stream and humidified exhaust air flow. The air outlet (15) is arranged above the water level (SP) of the water bath (W). According to the invention, the at least one air supply (8) ends below the water level (SP) of the water bath (W), so that the supplied air flow leaves the air cleaning chamber (2) via the air outlet (15) after at least partially flowing through the water bath (W).
