Estimated height hazards

In some cases, but "you can use the formula given in memory of CM-67. For the estimated heights of pollutant at least 30 m at a temperature difference between the outgoing and the outside air, equal to 10 В° C (for the most part takes place in the ventilation exhaust), and the volume of exhaust air is not less than 25 000 m3 / h (about 7,0... read more >>

dispersion of gases and dust in the atmosphere

Knowing at least approximately, how many are released into the atmosphere harm exhaust ventilation, is extremely essential was to establish the laws of their dispersal in the air surrounding industrial enterprise. Unfortunately, the problem of scattering of dust and gases in the atmosphere lit yet far from complete. Research in this area... read more >>

Duplication exhaust fans

Duplication of exhaust fans are often used in ventilation plants with toxic hazards. If the exhaust system removes a significant amount of gases, vapors, aerosols, PLI, and if you can not immediately stop the process and stop the allocation of pollutant, the duplication of exhaust fans required. With highly toxic gases may have to duplicate... read more >>

dust control

Dust control - the most difficult task parameters confectionery. So far, it is not completely resolved. This is explained on the one hand, small-scale mechanization of production and, on the other hand, the lack of attention by health authorities.

Insufficient scale of production does not allow to carry out continuous and sealing pylevydelyayuschih... read more >>

dust emission

Dust emission - a frequent and difficult localizable harmful. Industrial dust, as well as industrial gases, is diverse in composition and properties, the conditions of release and the action is exerted on the person.

Classification of industrial dusts can be made on different grounds. We mention some of them.

In action, exerted...

Efficacy of flare emissions

In late 1962 the laboratory by heating ventilation Institute of sanitary engineering work has been done on the topic "Investigation of the effectiveness of flare emissions." As a result of blowing in the wind tunnel stained jet Fig. 16. Distortion and erosion scab obtained very interesting pictures, showing the extent of erosion and distortion... read more >>

Electric aspiration systems

Motors aspiration systems are blocked with the electric dust-production and transport equipment. When the wet air pollution control water flow in the cyclones or scrubbers automatically stops when you stop the motor of aspiration system.

Motors exhaust alarm systems are sometimes blocked from automatic valves that feed fresh air PLI... read more >>

Emergency ventilation

Emergency ventilation in the production of titanium dioxide is not required. Local sucking fumes and gases from the reactors are arranged (except for the expansion of reactors), repulpatorov, thickeners and storage, in which there are solutions and suspensions with temperature above 50 В° C. Especially important local exhaust from vehicles... read more >>
