FIELD: transportation.
SUBSTANCE: installation comprises dispensing hopper for intermediate storage of granular or powdered material and pressure relief device in the dispenser hopper. The dispensing hopper is made for alternate increasing of the pressure for emptying the hopper and dispensing pressure relief to allow for its completion. Pressure relief device in the dispenser hopper contains a pressure relief pipeline connected to the dispensing hopper, bag filter, connected to the pressure relief pipeline and flow control devices for flow control in the pressure relief pipeline through the bag filter. Bag filter is a filter made for operation under pressure. Flow control devices are static control devices without moving elements disposed on the pressure relief pipeline downstream of the bag filter. Flow control devices comprise a plate with a bore of a given cross-section or de Laval nozzle.
EFFECT: provision of passing the maximum volumetric flow rate less or equal to the maximum allowable bag filter flow, thereby the unit weight reduces.
