Abstract

The present invention relates to a metering system for the steady, continuous, dosed supply of a bulk material in powder form made of light, polydisperse particles from a supply device (B, SG) into a plurality of conveying tubes (FR1, FR2, FR3) to a consumer arranged downstream. The metering system comprises at least two metering containers (DB1, DB2, DB3) each having a delivery device (AE2/1, AE2/2, AE2/3), the delivery device (AE2/1, AE2/2, AE2/3) for each of the conveying tubes (FR1, FR2, FR3) comprising a dust flow regulation device (FI1/1, FI2/1, FI3/2), which is assigned thereto and opens therein, and a mass flow measuring probe (FIC1, FIC2, FIC3) being arranged on each of the conveying tubes (FR1, FR2, FR3), which is coupled to the dust flow regulation device (FI1/1 to FI3/2) which opens into the corresponding conveying tube (FR1, FR2, FR3). Furthermore, the metering system has a pressure regulation device, which is coupled to the pressure measuring devices (PI1/1, PI1/2, PI1/3) arranged on the delivery devices (AE2/1, AE2/2, AE2/3), and which controls a metering container pressure (PIS2/1, PIS2/2, PIS2/3) at least as a function of a metering container fill level (LIS1, LIS2, LIS3). A pump device (V) can be coupled to each of the metering containers (DB1, DB2, DB3), which provides a pressure (PIS2/1, PIS2/2, PIS2/3) in the metering container (DB1, DB2, DB3), which is less than a pressure in the supply device (B, SG). Furthermore, the invention discloses a dense phase conveying system, which comprises the metering system and a method for the steady, continuous, dosed supply of a bulk material in powder form made of light, polydisperse particles.
