Embodiment Construction

[0023] Describe preferred embodiment of the present invention in detail below in conjunction with accompanying drawing:

[0024] A kind of cyclone form that the present invention designs, and structure sees Figure 4 , the inlet section shape see figure 2 . The inlet section shape of this type of cyclone is a cycloid inlet, the large cone angle is 10°, the small cone angle is 1.5°, the diameter of the overflow port is 4mm, the nominal diameter of the cyclone is 30mm, and the height of the cylindrical section is 60mm , the equivalent diameter of the inlet section is 13mm, the diameter of the tailpipe section is 15mm, and the length of the tailpipe section is 600mm. With this cyclone form, the inlet flow rate is 4m 3 / h and the split ratio of 8%, it is used for oil-water separation, the separation efficiency is 4.1% higher than that of Thew type cyclone, and the pressure drop is 7.6% higher than that of Thew type cyclone.

[0025] Another kind of swirler form that the prese...

Abstract

This invention concerns high-efficiency liquid-liquid hydrcyoclone with low consumption of . The cyclone comprises an overflow pipe (1) with inlet size Do / D of 0.1~0.2, cyclone inlet (2) with section shape of cycloid or catenary and equivalent diameter 0.3~4 times of cyclone nominal diameter, cylinder segment (3) with size of Lc / D 2í½3, steep segment (4) with cone angle of 8~25Deg, bevel segment (5) with cone angle of 1.5~6Deg, and liner segment (6) with size of Lu / D 20~40. This cyclone can used to separate oil-water mixture with inlet concentration less than 20%; compared with traditional cyclones, it has advantages of high efficiency, low pressure drop and wide application range.

Description

technical field [0001] The invention relates to a sewage degreasing hydrocyclone, which is suitable for treating oily sewage and the separation of other light dispersed phase liquid-liquid, liquid-liquid-solid, and liquid-liquid-gas mixtures, and belongs to a cyclone. Background technique [0002] The oil-water separation hydrocyclone is a double-cone structure, such as figure 1 As shown, it includes an overflow pipe 1, a swirler inlet 2, a cylindrical section 3, a large cone section 4, a small cone section 5 and a parallel tailpipe section 6. According to the patents of Thew et al. (CA119111, US4576724), the inlet section adopts an asymptote form, the half-cone angle of the small cone section is 20′~1°, and the diameter of the overflow port is less than 0.1 times the diameter of the cyclone. This cyclone can be used to separate the oil-water mixture with a split ratio of 0.5-10%. The separation efficiency depends on the size of the cyclone, the diameter of the oil droplet ...
