Abstract: Known devices for separating liquids using parallel-connected cyclones, when gas flows are fluctuating, have a poor separating action. In the device of the invention, the separating action is conversely improved by providing that the number of separator elements through which the gas flow flows is adapted in each case to the gas flow. When the gas flow is high, there is a flow through more separator elements than when the gas flow is low. In this way, the separator elements are operated closer to the optimal operating point than in the prior art. According to the invention, it is proposed that a closing body (11) of a distributor valve (13) be disposed movably in a distributor conduit (10) and either automatically or by means of a drive mechanism adjusts the optimal number of separator elements (16) through which there is a flow.

Abstract: A dust collection system for portable sanding or grinding equipment employs a cyclone separator mounted directly on the tool or machine, with a dust outlet duct at the narrow lower end of the cyclone, and a cartridge air filter mounted on the top of the cyclone. The filter returns the air flow from the machine to the ambient air in the vicinity of the tool. The dust is concentrated in the cyclone, and a small volume air flow then moves the dust through an elongated flexible hose or duct to a remote dust collection station. An air pump at the remote dust collection station provides sufficient air flow to draw the small volume of air plus entrained dust from the tool-mounted cyclonic separator. A cyclonic separator at the remote station separates this dust from the air flow and deposits it in a collection tank or drum.

Abstract: A pressurized fluidized bed reactor is provided utilizing a centrifugal separator having a gas space that is distinctly non-circular, preferably having a circularity of greater than or equal to 1.15. Most desirably the cyclone has a quadrate (e.g. square) cross-section, and is disposed inside of the pressure vessel along with the reactor chamber containing the fluidized bed.

Abstract: A novel arrangement of cyclone and plenum assembly and support therefor wherein the plenum is a totally separate vessel and is suspended from the main vessel shell on pinned connectors to thereby provide for unrestrained vertical and horizontal movement. In turn, the cyclone weight or load is supported directly from the outer periphery of the plenum chamber in a manner to allow direct load transfer from the heavy cyclones directly upward through the brackets and pinned connectors to the main vessel shell.

The use of relatively short radial bracket members on the outer periphery of the plenum chamber, to which the pivoted support links are connected, minimizes the length of the support beam to which the combined load of the cyclones and the plenum is applied.
