Review article

The article presents the results of the air quality survey in production premises and within the sanitary protection zone of the factory producing lead-acid batteries. The use of the old equipment and «open» technological processes leads to the air environment pollution of industrial premises and industrial sites above the permissible values. The analysis of the existing irrotational air diffusers (namely, the ventilation facilities in the form of panels available at the factory) performance has been carried out. Using the method of mathematical modeling, the effect of the aerodynamic mode of the production premises (the lateral velocity component) on the efficiency of the operation of the ventilation panels installed in production workshops, is demonstrated. It is shown that with a lateral velocity component exceeding 0.5 m/s, the vertical low turbulent air current from the ventilation panels is broken down, and the production efficiency of these panels is considerably reduced.
