the improved chemical biological and radiological Decontaminating Equipment with air suction function and preventing reverse liquid flow

摘要

The present invention relates to a device for sucking air and jetting air and liquid together, comprising: a casing 100 having a hollow therein; And an inner pipe 200 inserted into the casing 100. The coupling between the inner pipe 200 and the casing 100 includes a liquid injecting portion A; Venturi (B); Mixing portion (C); And an air orifice 210 in which air is sucked into the inner pipe 200 located at the venturi portion B, the air orifice 210, the air nozzle 210, orifice is formed to have an eccentricity (e) at the center of the inner tube (200) on a horizontal cross-section so as to facilitate the suction of the air using centrifugal force and allow the air and the liquid to smoothly flow. An air suction nozzle having improved suction performance is provided. A casing 100 for sucking air and jetting the air and liquid together, the casing 100 having a hollow therein; And an inner pipe 200 inserted into the casing 100. The coupling between the inner pipe 200 and the casing 100 includes a liquid injecting portion A; Venturi (B); Mixing portion (C); And an air orifice 210 in which air is sucked into the inner pipe 200 located at the venturi portion B, the air orifice 210, the air nozzle 210, orifice is formed so as to have an inclination angle (?) from the outside to the inside of the inner tube (200) on a vertical section so as to prevent the backflow of the liquid during the air sucking operation. do. In addition, the present invention provides a cyanogen decanter equipped with an air suction type nozzle having improved air suction performance or liquid backflow prevention function using an air suction type nozzle, or an air suction type nozzle having improved liquid backflow prevention function.
