Abstract

The invention relates to a vacuum installation for industrial application, the installation comprising a first vessel having a first gas inlet for allowing a gaseous substance into the first vessel and a first outlet for depletion of a material, a second vessel having a second inlet for aspirating a quantity of material and a second gas outlet for depletion of the gaseous substance, wherein the gaseous substance comprises a vapour generated from the material, a storage chamber for storing the quantity of material, the storage chamber having a third inlet, wherein at least the first vessel communicates with an interior of the storage chamber via the first outlet and the third inlet; and a vacuum pump located in between the first vessel and the second vessel, and operated to lower the pressure in the second vessel, thereby allowing the material to be sucked into the second vessel via the second liquid inlet to an equilibrium level between the material and the gaseous substance, the vacuum pump being further operated to transport the gaseous substance to the first vessel to raise the pressure in the first vessel, thereby forcing the material in the first vessel into the storage chamber.

Abstract

A vacuum installation includes a vacuum chamber having an inlet for aspirating a quantity of liquid or particulate material. A cyclone separation unit having a plurality of cyclones, communicating in parallel with the interior of the vacuum chamber is connected to a vacuum pump to draw air from the vacuum chamber through the cyclones and induce a separating vortex flow within the cyclones. A controller is arranged to control the vacuum pump to provide a chosen flow rate and to selectively deactivate one or more of the cyclones according to the chosen flow rate.
