| Title of the article | To the question of the influence of suction irregularity on the exhaust air volume |
| Abstract. | In some cases, technological equipment releases harmful substances as vapors, gases, dust, etc. In order to create the required sanitary-hygienic conditions the workplace is arranged by exhaust ventilation – a local suction. The overall performance is determined by the uniformity of suction of pollutant emission. However, such a requirement is valid only in a coaxial arrangement of the «source» – a «sink». If it is not an important role on the local ventilation performance affects the condition of suction irregularity throughout the hight of the holes. This paper considers the case of out of alignment location of the system the «source» – a «sink». Analytically received dependence affords to determine the velocity of suction throughout the hight of the air inlet at any angle of out-of-alignment of the system the «source» – a «sink». Obtained dependences were verified experimentally by using the shadow device «Toepler». The irregularity suction throughout the hight of the air inlet was regulated by the installation of internal screen. The volume of exhaust air by using the air inlet with the irregular suction was 40-60 % less than in the same conditions but in equally suction air inlet. The discrepancy between the flow of exhaust air was calculated according to the dependences obtained in the experiment, was 13 % at an out-of-alignment angle of 90 degrees, and 18 % for an out-of-alignment angle of 180 degrees. |
