Problems solved by technology

[0004] In practice, this type of cyclone produces relatively high friction, which results in a higher pressure drop and greater energy loss
Cyclone efficiency will also be lower than other types of cyclones

Embodiment Construction

[0028] Figures 1A-1C A typical embodiment of a sheet metal swirler 1 is shown, comprising a peripheral ring 2, a central part 3 and three radially equidistant vanes 4 bridging the central part 3 and the peripheral ring 2 . The blades 4 are identical in size and shape. The vane 4 has a flow inlet portion 5 at the flow inlet side edge 6 and a flow outlet portion 7 at the flow outlet side edge 8 .

[0029] Such as Figure 1C As shown, the flow inlet portion 5 delimits an inlet angle α of approximately 90° to the plane passing through the ring 2 and the central portion 3 , said plane constituting the plane of the original sheet metal blank. The flow outlet portion 7 defines an outlet angle β of approximately 40 degrees. The flow inlet side edge 6 is truncated substantially perpendicular to the direction of flow (eg Figure 1C Indicated by the arrow A in).

[0030] In the illustrated embodiment, the flow inlet portion 5 of the vane 4 is gradually curved from having an inlet ...

Abstract

Separation device comprising a swirler (1, 20, 30) of a sheet material comprising a plurality of vanes (4) with a flow entrance side edge (6) defining an entrance angle (alpha) and a flow exit side edge (8) defining an exit angle (beta). The flow entrance side edge and flow exit side edge extend from a center section (3) to a peripheral edge (9), which extends between end points of the flow entrance edge and the flow exit edge. The entrance angle is larger than the exit angle. The swirler can me made from a blank (10) by cutting out cutting lines defining the peripheral edges, the flow entrance edges and flow exit edges of a plurality of vanes (4) of a swirler. The vanes are subsequently bent to define the exit and entrance angles. Optionally, the swirler can be stacked with one or more correspondingly cut and bent swirlers to form a single stacked swirler (20, 30).

Description

technical field [0001] The invention relates to a separation device comprising a swirler cut from sheet material and comprising a plurality of blades. Background technique [0002] Cyclones are used in separation devices for separation, they create centrifugal eddies in a fluid flow, such as a gas or a liquid, optionally containing solid particles. Typically a cyclone is used to separate the liquid components from the gas. [0003] In low-cost applications, the swirlers may be cut from sheet material (eg, sheet metal or billet). The swirlers can be formed by cutting starting from a metal blank, for example by laser cutting, with radial cuts separating adjacent blades, such that the radius of the annular peripheral cutting line corresponds to the channel (the swirler will be placed in where) radius. [0004] In practice, this type of cyclone produces relatively high friction, which leads to a higher pressure drop and greater energy loss. The cyclone efficiency will also b...
