Calculating the exhaust ejection system in the ventilation of the painting chamber

Abstract

Problem statement: The ventilation system plays a decisive role in the creation of the
microclimate in various premises. It is known that the ejection ventilation system is well
proven both for high-rise residential and office buildings, and for industrial premises. All
paint coatings are corrosive and easily flammable substances. In addition, solvent vapors are
explosive. It is therefore desirable to use ejection ventilation system in the design of the
ventilation system of paint booths. The ejector is simple in design; it can work in a wide
range of parameters of state of steam-air mixtures.
Results: The calculation and design of a low-pressure ejector have been performed. An
ejection ventilation system has been synthesized using the universal modeling package
ChemCad that contains highly developed database to calculate thermophysical properties of
various substances and their mixtures.
Conclusions: The obtained results can be recommended in the layout of the ventilation
gadget of paint booths both new and reconstructed. The Usage of the software allows
carrying out multiple calculations, which are indispensable for the solution of optimization
problems.
