Title Local push-pull exhaust ventilation for surface treatment vats
Original title Nawiewno-wywiewna wentylacja miejscowa przy wannach z kąpielami technologicznymi [in Polish]
Bibliographic information 1982, Vol.32, No.114, p.201-217. Illus. 38 ref.
Abstract Studies aimed at optimising the characteristics of the system to obtain maximum economy of energy and improved safety and health conditions, with particular reference to electroplating shops, are described. Aspects studied were laminar air flows drawn along the surface of the open baths, exhaust spectra of the exhaust hoods and their interaction with total enclosure of the vat. The results were combined with data from the world literature to generate flow parameters and construct a push-pull device for vats of Polish manufacture, taking the particular requirements of automatic electroplating into account. This type of ventilation is effective and allows the total air flow in vats more than 0.7m in width to be reduced by half compared with local exhaust ventilation systems.
