FIELD: mechanical engineering. SUBSTANCE: device has impeller pump. A worn is mounted in the inlet branch pipe of the pump. The device is equipped with conic gas intakes uniformly set along the circumference of the inlet branch pipe in front of the worn and disposed in the plane perpendicular to the pump axis of rotation. The intakes have axles parallel to the tangents to the branch pipe circumference in the place of the intake mount. The greatest diameter of the intake makes up 0.084-0.09 of the worn diameter. The distance from the edge of the greatest diameter of the intake to the worn and to the branch pipe walls makes up 0.02-0.025 of the worn diameter. The device has an assembled collector, exhaust pipes connecting the intakes and the assembled collector and a partition in the shape of a frustum. The partition is mounted in the branch pipe in front of the intakes. The smaller foundation of the partition is directed towards the intakes. The axis of symmetry of the partition coincides with the branch pipe axle. The greater diameter of the partition is equal to the inner diameter of the branch pipe. The plane of the smaller diameter of the partition is disposed at a distance of 0.1-0.115 of the worm diameter from the branch pipe wall. The distance from the plane of the smaller diameter of the partition to the plane of the intake axles is equal to 0.072-0.100 of the worm diameter. EFFECT: facilitated manufacture. 2 dwg, 2 tbl
