  • Installation for distributing pulverulent substance by pneumatic transportation, comprising a device for depressurizing a pressurized reservoir in which said substance is stored
    Patent number: 10823506
    Abstract: An installation for distribution of granular or powder material via pneumatic transport comprising at least one dispensing hopper (3) for temporary storage of said granular or powder material, the dispensing hopper being suited to being, alternately, pressurized for emptying the dispensing hopper and depressurized to permit filling thereof, and a device for depressurizing said dispensing hopper. The depressurizing device comprises a depressurizing duct (12) connected to said dispensing hopper, a bag filter (11), having a maximum operating flow rate, connected to the depressurizing duct, and flow control means (15) for controlling the flow rate in said depressurizing duct through the bag filter. The bag filter (11) is suited to operating under pressure, and the flow control means (15) are located on the depressurizing duct (12) downstream of the bag filter (11) and are arranged to provide a flow rate which is at most equal to the maximum flow rate of the bag filter.
