摘要:
A vacuum installation comprises a vacuum chamber having an inlet for aspirating a quantity of liquid or particulate material. A cyclone separation unit comprising 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.
摘要:
The cyclone is for separating gas from a gas laden liquid stream by pressure reduction of the liquid stream. The cyclone has a cylindrical casing, having a tangentially directed inlet arrangement for the gas laden liquid stream, a lower outlet line for liquid and an upper outlet line for vapor and gas. The inlet arrangement is connected to a common supply source (BLPR), and has at least two insertion pipes. The flow in at least one of these insertion pipes is controlled by at least one valve that depends upon an order of flow from the common supply source to maintain a flow velocity above a critical value.

A vacuum installation (2) comprises a vacuum chamber (4) having an inlet (24) for aspirating a quantity of liquid or particulate material. A cyclone separation unit (6) comprising a plurality of cyclones (10), communicating in parallel with the interior of the vacuum chamber is connected to a vacuum pump (20) to draw air from the vacuum chamber through the cyclones and induce a separating vortex flow within the cyclones. A controller (50) 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.
摘要:
A multi-cyclone collector includes a suction port (11) for sucking an air flow including contaminating particles, a cyclone accommodation chamber (12) allowing the sucked air flow to be guided thereinto, a plurality of cyclones (13) accommodated in the cyclone accommodation chamber (12), a cyclone exit chamber (23) allowing a purified air flow from the cyclones (13) to be guided thereinto, and a drain discharge chamber (51) for collecting the contaminating particles separated by the cyclones (13). Each of the cyclones (13) has a swirling portion (131) allowing a downward swirl flow to travel therethrough, a reversing portion (132) for reversing the swirl flow to the upward swirl flow, and a discharge pipe (134) for guiding the contaminating particles separated from the air flow into the drain discharge chamber. The discharge pipe (134) has a lower opening (134a) sealed by liquid (56) stored in the drain discharge chamber (51). There is provided a communication pipe (24) for controlling liquid level so that the liquid in the discharge pipe (134) does not reach the reversing portion (132).
