Problems solved by technology

Secondly, most of the existing hydrocyclone devices use a structure in which the water outlet and the oil outlet are located on different sides of the device. In this way, there are swirl movements in multiple directions inside the cyclone, resulting in unstable flow field and po

Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing:

[0017] Such as figure 1 As shown, this kind of outflow reverse cone high-efficiency cyclone separator in the same direction includes the inlet pipe 1 of No. The general hydrocyclone structure such as the upper sealing surface 12 and the lower sealing surface 6 at the end, but the unique feature is that this kind of cyclone separator abandons the conventional cylindrical cyclone cavity, and adopts the above, Between the lower sealing surfaces, there are structures such as a truncated swirl chamber section 2 , a large cone section 11 , a small cone section 4 , a tailpipe section 5 and a cylindrical outlet section 9 in sequence. In this new structure, the upper sealing surface 12, the swirl cavity section 2, the large cone section 11, the small cone section 4, the tailpipe section 5, the outlet section 9 and the lower sealing surface 6 are sequentially connected to form an I...

Abstract

The invention relates to an equidirectional drainage reverse taper type high-efficiency rotational flow separator, which mainly solves the problems of poor separation effect of tiny oil drops, large volume and inconvenient installation of the traditional hydraulic cyclone separator. The invention is mainly characterized in that a rotational flow cavity section, a large taper section, a small taper section, a tail pipe section and an outlet section are successively distributed between upper and lower sealing faces; the components form a rotational flow cavity body gradually converged towards the central axis after being successively connected; a tapered thimble in the rotational flow cavity body is fixed on inner side surface of the upper sealing face; the taper top of the tapered thimble points to one side of the lower sealing face; an oil outlet pipe is vertically and fixedly connected to the lower sealing face through the center of the lower sealing face; the pipe orifice of the oil outlet pipe is positioned on the lower part of the taper top of the tapered thimble; and a water outlet pipe is horizontally connected to the bottom end of the outlet section along the tangential direction of a cycle. The rotational flow separator has the characteristics of good elimination effect on the tiny oil drops. Compared with the traditional hydraulic rotational flow separator, the rotational flow separator has the advantages of stable flow field and high separation efficiency, and is convenient for technological installation.

Description

technical field [0001] The invention relates to a two-phase separation treatment device applicable to the fields of petroleum, chemical industry, environmental protection and the like, in particular to a hydrocyclone separation device. Background technique [0002] At present, the methods for rapid separation of two-phase mixtures mainly include cyclone separation, air flotation, filtration and membrane separation. Each of these methods has its advantages and disadvantages. For example, the cyclone separation method has the advantages of small equipment volume, but its ability to remove fine oil droplets is very limited; the air flotation method is only suitable for situations where the oil concentration varies within a small range; Although the filtration method can achieve the separation of oil and water phases, frequent backwashing is required to ensure the long-term stable operation of the equipment for highly oily sewage; the equipment used in the membrane separation me...
