The inventive device is connected to a pipeline (1) and comprises an cylindrical inlet part (2) provided with a grid (3) arranged at entrance to an annular chamber (4) fitted with a high pressure sensor (5), a perforation (6), a double-tube injector (7) which is divided, by means of a point of inflection of a curved generating surface of the injector into a convex part of a curved generatrix and a concave part thereof. The curved part defines a surface profile of the first stage (8) of the injector, and the concave part defines a surface profile of the second stage (9) of the injector. Said device also comprises a cylindrical branch pipe (10) having a double-stage inner cavity with a perforation (11) which is connected to an annular chamber (12), a low pressure sensor (13), to a conical nozzle (14) and washing sleeves (15 and 16).
