Hydrocyclone Structure,Advantages and Disadvantages

Hydrocyclone Structure. The top half of hydrocyclone is a cylinder which installed a feed pipe. The feed pipe is co-tangent direction of cylinder. In this way, under the pressure from pumps slurry is fed into hydrocyclone and make rotary motion along inside cylinder wall.

Enhancement of hydrocyclone performance by controlling the ...

A common hydrocyclone was designed according to Rietema's optimum geometry for separation (Rietema, 1961; Svarovsky, 1984).The hydrocyclone geometry is shown in Fig. 1. With the same geometric parameters, a new hydrocyclone was designed with a winged core to control the turbulence structure in the inner helical flow below the vortex finder, as shown in Fig. 2.

Research on the structure of the cylindrical hydrocyclone ...

Although the structure of the hydrocyclone is uncomplicated, the internal flow field is very complicated [5,7,8]. In the actual separation process, there is a phenomenon that some particles are misplaced both in the overflow and the underflow [ 9 ].

Hydrocyclone flow characteristics and measurements ...

Hydrocyclone structure. As seen in Fig. 1, the hydrocyclone is comprised of the following parts: a cylindrical top connected to a conical base, a central upper overflow tube (the vortex finder), and a central lower discharge tube (the apex). Attached to its cylindrical top, the hydrocyclone has an entry section called the inlet valve through ...

Structure of Hydrocyclone. The upper part of the cone is conical; a feeding pipe tangent to the cylinder wall is installed on the cylindrical cylinder; a central overflow pipe connected with the cylindrical part is installed on the upper part of the cone; the upper end of the overflow pipe is connected with the external pipe through the buffer chamber or directly to discharge the overflow; and ...

The second structure of secondary vortices is shown in the bottom of Fig. 6. The upward flow near the axis and the downward flow near the wall of hydrocyclone is a reason behind the structure of vortices in cylindrical and the following conical section. The structure of flow inside deoiling hydrocyclones will be discussed in the next section. 6.2.

Effect of structural modification on hydrocyclone ...

The structure of hydrocyclone was designed with a series of modifications, and the comprehensive effects of the structural modifications on operation performance indices of hydrocyclones were investigated experimentally with orthogonal design method. Based on the conventional hydrocyclone, the structural modifications with central insertions ...

Hydrocyclone structure: The upper part of the Hydrocyclone is a hollow cylinder, and the lower part is an inverted cone connected with the cylinder. The two constitute Hydrocyclone Simple operation. The upper end of the cylindrical cylinder is provided with a feed pipe tangentially, and the top is provided with an overflow pipe and an overflow ...

Hydrocyclone - Wikipedia

Hydrocyclones are of cyclonic separators that separating product phases mainly on basis of differences in gravity with aqueous solutions as the primary feed fluid. As opposed to dry or dust cyclones, which separate solids from gasses, hydrocyclones separate solids or different phase fluids from the bulk fluid. A hydrocyclone comprises a ...

SPE 28815 The Separation of Solids and Liquids with ...

Hydrocyclones operate under pressure. Fluid is directed tangentially into the hydrocyclone which causes it to spin. The spinning motion generates strong centrifugal forces which induces the solid and liquid, or the two immiscible liquids, to separate. The centrifugal force generated in a hydrocyclone varies over its length, and may reach a ...

The structure of the Type O hydrocyclone was the same as that of Type A-I, except for the inlet conduit. The inlet of Type O was rectangular with a width of 2.5 mm and height of 1.6 mm; therefore, it had the same cross-sectional area as Type A-I.

CFD Study on the Effect of Hydrocyclone Structure on the ...

Abstract Effects of geometric structure parameters of 10 mm-diameter hydrocyclones on the particle separation efficiency are studied using computational fluid dynamics (CFD). The fluid velocity profiles and particle trajectories are simulated using RFLOW software with a standard isotropic k-ε turbulent model. The JIS standard CaCO3-17 particles are adopted as a particulate sample in ...
