Reduction Outgassing
To reduce evaporation and odors, an air curtain is used over these galvanic baths. The chemicals dissolved in it can be a burden on the health of employees. To reduce this, it was decided to have the curtains calculated with CFD software. The volume flow, speed and angle of blowing are all inventoried with the model and optimized for this application.
Flow simulation of thermal blanket.
Controlled airflow, aerodynamics, over galvanic baths can reduce evaporation and improve air quality. The assignment was: Reduce evaporation from galvanic baths with a temperature of 80 C, and save on energy costs in the factory hall. The evaporation of the baths was partly inspired by the ARBO legislation. Simulate the air flow with a patented jet from To Improve. The aerodynamic simulation of evaporation and the therefore expected concentrations of vapor gave a higher concentration directly above the bath in the To Improve system. A higher vapor concentration directly above the bath ensures less evaporation, while a smaller extraction flow rate prevents the spread of vapor to the environment. Assessment of different variants (discharge speed, supply angle) led to further optimization of the push-pull system.
Result
From the simulations a setting was determined that was tested in practice. The effects that were seen in the simulation were seen in the tests in the factory hall. The settings resulted in an energy saving of more than 25%, and the evaporation and mixing with the ambient air decreased by the same percentage. An additional advantage was that the ventilation system in the factory hall can work at a lower setting, so the energy saving is doubled here!
