A liquid sprayer comprises a casing (1), a discharge nozzle (2) and a liquid feeding branch pipe (3). A circular passage formed between the inner surface of the casing (1) and the branch pipe (3) is connected to the discharge nozzle (2) through guiding passageways (7). The end part of the liquid feeding branch pipe (3) and the part of the discharge nozzle (2) facing said end part of the branch pipe are formed as conical surfaces. The profiled channel of the discharge nozzle (2) comprises sequentially arranged an inlet circular portion converging in the course of flow and an outlet cylindrical portion joined to the latter. The inlet portion is defined between the conical surface of the end part of the liquid feeding branch pipe (3) and the conical surface of the discharge nozzle (2). The sprayer provides for effective generation of a finely dispersed gas-and-droplet flow with uniform distribution of monodispersion liquid droplets within the flow. |
