FIELD: transport. ^ SUBSTANCE: in transportation, material is fed into transportation channel and, further on, into separation device (5) wherein carried material is separated from transportation air. Note here that negative pressure in transportation channel is generated with the help of ejector device (6) with its suction side communicated with separation device (5). Ejector device operates using fluid mist to be sprayed through nozzle (122) into ejector tube (128) running into separation element inside a section of shell (142). Negative pressure is increased to limit gas flow, for example airflow, in ejector tube on the side opposite the direction of fluid mist spraying. Transportation gas flows through shell outlet hole. ^ EFFECT: higher efficiency of suction by ejector device. ^ 26 cl, 7 dwg |
