Embodiment

[0016] Double inlet hydrocyclone separator, such as figure 1 , figure 2 with image 3 As shown, it includes 1 water inlet pipe, 2-1 water outlet pipe, 2-2 overflow pipe, 3 bell mouth, 4 inner cylinder cylinder section, 5 inner cylinder cone section, 6 underflow residue bucket, 7 outer cylinder, 8 Flow meter probe interface, 9 reserved working line window, 10 screw socket interface. The inlet of the hydrocyclone separator is a double-inlet design. The sewage or rainwater containing suspended particles first flows into the separator tangentially through the water inlet pipe 1, and then rotates. The inner wall slides down to the underflow residue bucket 6; after the supernatant passes through the inner cylinder section 4, passes through the bell mouth 3, and finally flows out of the outlet pipe 2-1; -2 goes deep into the underflow residue bucket 6 and absorbs it. The nominal diameter of the inner cylinder of the double-inlet hydrocyclone is DN500mm, and the nominal diameter ...

Abstract

The invention discloses a hydraulic cyclone separator with two inlets. The hydraulic cyclone separator with the two inlets comprises an inner barrel and an outer barrel. The inner barrel comprises a cylindrical section and a conical section and is characterized in that the cylindrical section is provided with the two inlets, a water outlet pipe and an overflow pipe; the conical section is provided with an underflow opening and an underflow residue lifting bucket; the two inlets are arranged in the vertical direction of 90 degrees; the equivalent diameter of each inlet is 0.15-0.25 time the diameter of the separator, spiral tangential water feeding is adopted, the radius of curvature of the inner side of each inlet is 0.75-1.0 time the diameter of the inner barrel of the separator, and the radius of curvature of the inner side of each inlet is 0.55-0.75 time the diameter of the inner barrel of the separator; and the diameter of an opening connected with the cylindrical section of the inner barrel is 0.10-0.30 time that of the inner barrel of the separator. In order to overcome the defects that a traditional single-inlet hydraulic cyclone separator is small in processing capacity, poor in adaptability to connection with municipal pipes and poor in processing effect, a double-inlet spiral tangential inflow mode is adopted, and by optimizing the inlet water flow direction, the processing scale is increased, and the processing capacity is improved. Meanwhile, the separation effect is further improved.

Description

technical field [0001] The invention relates to accessories for a solid-liquid two-phase separation process, and discloses a double-inlet hydrocyclone separator with high-efficiency separation and dual-inlet functions. Background technique [0002] The cyclone separator is a device that uses the principle of centrifugal sedimentation to separate, classify or sort two-phase (or multi-phase) media from a suspension. Since the liquid is often an aqueous medium, it is also called a hydrocyclone (or cyclone separator). The main body of the equipment is composed of a cylinder and a cone. The suspension enters the cylinder tangentially through the inlet pipe and moves downward in a spiral shape. The solid phase particles tend to settle to the wall of the cyclone under the action of centrifugal force. Due to the large centrifugal force, the coarse particles move to the wall of the cyclone and are discharged from the bottom of the cyclone with the external cyclone to form an underfl...
