A kind of hydrocyclone with cone slit structure

Abstract

The invention discloses a hydrocyclone for a cone slit structure. The hydrocyclone comprises a material feed tube, a cylinder section, a cone section, a sleeve, an overflow tube, and a bottom flow tube, wherein slits are formed in the middle lower position of the wall of the cone section, the slits are distributed uniformly and circumferentially with a central axis of the cone as a center line, the bottom of the cone section is sealed, and a separated heavy phase slides from the cone section to the sleeve in a slit tangential direction and is discharged by the bottom flow tube. Compared with aconventional hydrocyclone of the same size, the hydrocyclone with the cone tangential slit structure maintains high separation efficiency of the conventional hydrocyclone, greatly lowers pressure drop, and can be applied to occasions requiring high energy consumption, such as internal process strengthening of a slurry bed reactor.

Description

technical field [0001] The invention relates to the technical field of liquid-solid separation, in particular to a hydrocyclone with a cone-shaped slot structure. Background technique [0002] Hydrocyclones are often used in the field of solid-liquid separation. The basic principle is the same as that of a centrifuge, so that the suspended particles in the solid-liquid two phases are separated from the liquid under the action of centrifugal acceleration. It is widely used because of its simple structure, low equipment cost, small footprint and large processing capacity. [0003] Pressure drop is an important technical index and operation index of hydrocyclone. The pressure drop of hydrocyclone should be as small as possible to reduce energy consumption. The traditional conventional hydrocyclone has a "one column and one cone" structure. Generally, the pressure drop of the fluid passing through the cyclone is controlled below 0.3MPa during operation. It is more common to op...

AI Technical Summary

Problems solved by technology

The traditional conventional hydrocyclone has a "one column and one cone" structure. Generally, the pressure drop of the fluid passing through the cyclone is controlled below 0.3MPa during operation. It is more common to operate the hydrocyclone near the pressure drop of 0.1MPa , if the pressure drop is too large, it will be difficult for general industrial pumps to provide their inlet pressure

Especially for small-sized hydrocyclones with high separation capacity, the pressure drop will increase sharply when the processing capacity is large, resulting in huge power consumption of the pump

Large pressure drop and high energy consumption have become one of the main factors restricting the processing capacity and application range of hydrocyclones
