Изобретение относитс  к черной металлургии , а именно к контролю кислородно-конвертерного процесса.FIELD OF THE INVENTION The invention relates to ferrous metallurgy, in particular to the control of an oxygen converter process.

Известно устройство дл  отбора пробы отход щих газов сталеплавильного агрегата, включающее концентрически расположенные трубы, внешн   из которых снабжена коническим соплом.A device is known for sampling waste gases of a steel-smelting unit, comprising concentrically arranged pipes, externally provided with a conical nozzle.

Однако в известном устройстве имеет место значительна  запыленность отбираемых газов.However, in the known device there is a significant dust content of the selected gases.

С целью получени  достоверных проб сопло выполнено сужающимс  к открытому концу и имеет на внутренней поверхности винтовую нарезку . Кроме того, наружна  поверхность внутренней трубы имеет В(Интовую нарезку на прот жении 2-3 диаметров трубы.In order to obtain reliable samples, the nozzle is made tapering towards the open end and has a screw thread on the inner surface. In addition, the outer surface of the inner tube has B (Intra cutting over 2-3 pipe diameters.

На чертеже показано предлагаемое устройство , общий вид.The drawing shows the proposed device, the overall appearance.

Устройство включает две концентрически располол енные трубы / и 2. Внешн   труба / имеет коническое сопло 3, снабженное на внутренней поверхности винтовой нарезкой, а конец внутренней трубы 2 утоплен относительно выходного отверсти  сопла 3 на 0,5-0,8 диаметра внутренней трубы. Наружна  поверхность внутренней трубы также может иметьThe device includes two concentrically arranged pipes / and 2. The outer pipe / has a conical nozzle 3, provided on the inner surface with a screw thread, and the end of the inner pipe 2 is recessed relative to the outlet of the nozzle 3 0.5-0.8 times the diameter of the inner pipe. The outer surface of the inner tube may also have

винтовую нарезку на прот жении 2-3 диаметров трубы от ее конца.screw cutting over 2-3 pipe diameters from its end.

Устройство работает следующим образом.The device works as follows.

Через зазор между внутренней 2 н наружной / трубами подают пар под давлением 0,5 ати при температуре 160°С. Пар, выход щий из конического сопла 3 с винтовой нарезкой, создает вокруг отборного отверсти  внутренней трубы 2 завихренную паровую завесу, сквозь которую из газохода просасывают пробу газа в трубу 2 с остатками пара. Пар одновременно служит дл  охлаждени  поверхности устройства , омываемой гор чими отход щими газами .Through the gap between the inner 2 N outer / pipes steam is supplied under a pressure of 0.5 MPa at a temperature of 160 ° C. The steam coming out of the conical nozzle 3 with screw thread creates around the selected opening of the inner tube 2 a swirling steam curtain through which a gas sample is sucked from the gas duct into the tube 2 with steam residues. The steam also serves to cool the surface of the device washed with hot exhaust gases.
