On the Question of Ventilation of Industrial Enterprises in Kazan

Abstract

This article, using the examples of Kazan enterprises, highlights the issue of errors that can be in the device of industrial ventilation and the possible consequences of this. Natural ventilation is the cheapest and most effective type of ventilation, which, however, is often not used or used insufficiently. Aeration (organized controlled natural ventilation) is not carried out even in new factories. If sometimes there are aeration devices (overhead skylights with transoms), then there are no mechanisms to control them, which is why they are often not used. Non-blown lanterns, which allow the use of aeration devices without control mechanisms, have not taken root in Kazan either. Air showers and air curtains are a necessary supplement to aeration. Air showers, as you know, are local forced ventilation, which helps to eliminate harmful effects (heat, poisonous vapors, dust) in a small area of ​​the workshop. They are widely used in blacksmiths, foundries, power plant machine rooms, etc.
