Cyclone separator

Abstract

The invention provides a cyclone separator (1), comprising an inlet section (2), a first cone (3) and a current stabilizing section (7) that are connected in order, wherein the inlet section (2) is provided with at least one tangent inlet (11); a current inlet pipe (8) is connected with the tangent inlet (11); the first cone (3) is a cone downwards shrinking; the current stabilizing section (7) is a slender cylindrical pipe; its tail is equipped with an outlet (12); the separator further comprises a second cone or shrinking body (4) positioned above the inlet section (2) and connected with the same; the second cone or shrinking body (4) upwards shrinks and has a top opening (14); a cylinder body (10a) is installed along the centre axle line of a cyclone, and is hollowed at least from the vicinity of the middle part of the inlet section (2) to the top opening (14); and the cylinder body is closed close to the middle part of the inlet section (2), and the top thereof is opened; and the hollowed side wall of the cylinder close to the closed position is provided with a hole communicated with the top.

Description

technical field [0001] The invention relates to a cyclone separator, in particular to a cyclone separator for liquid-liquid, solid-liquid and gas-solid separation. Background technique [0002] As a common separation and classification equipment, the cyclone separator works on the principle of centrifugal sedimentation. When the two-phase or three-phase mixed liquid to be separated enters the cyclone tangentially from the periphery of the cyclone at a certain pressure, a strong rotational shear turbulent movement is generated. Due to the difference in particle size or density between the coarse particles or heavy phase and the fine particles or light phase, the centrifugal force, centripetal buoyancy, fluid drag, etc. are different in size, and most of the coarse particles or heavy phase It is discharged through the bottom outlet of the cyclone, and most of the fine particles or light phase are discharged from the overflow pipe, so as to achieve the purpose of separation an...

Problems solved by technology

At this time, if the above-mentioned cyclone oil-water separator is used to treat sewage with low oil content, the water content of the oil discharged from the oil outlet pipe may be relatively high, especially when separating sewage with large oil content or high viscosity, the effect is relatively poor

In addition, because the pressure of various oily sewage at the inlet is different, or often fluctuates, a stable reverse flow oil core cannot be obtained, and the separated oil cannot flow smoothly from the small oil spill, which may also cause separation. The oil and water remix, which is not desired

[0007] When the cyclone centrifugal separation is applied to the separation of solid-liquid, gas-solid, and gas-liquid, there are similar problems, that is, a short circuit is prone to occur between the inlet of the cyclone centrifugal separation and the light phase outlet, resulting in poor separation effect
