Description

Spiral-flow type two-phase filter

Technical field

The present invention relates to a kind of fluid filter in petroleum industry oil gas treatment facility, especially a kind of spiral-flow type two-phase filter.

Background technology

At present; unit's metering system is in oil field extensive use; mass flowmenter is as the key equipment of unit's metering; play an important role; but in use; often can run into that to cause mass flowmenter to walk liquid not smooth because the floccule in solid impurity and liquid stream stops up, affect the normal metering of mass flowmenter. The tamper of the conventional basket filter cleaning of field by using at present, by inlet outlet pressure differential operation, causes energy consumption when work, though can effectively clear up solid impurity, cannot remove the floccule in liquid, causes mass flowmenter still can often stop up; In addition, while clearing up filter solid sundries, need stoppage in transit mass flowmenter at every turn, pour liquid into by-pass operation, affect mass flowmenter data metering, cause the inaccurate of the data of making an inventory of goods in a warehouse.

Summary of the invention

Object of the present invention is intended to solve the defect that existing basket filter exists, provide a kind of practicality simple, can reduce the spiral-flow type two-phase filter of impurity screening to work influence.

Object of the present invention can realize by following technical solution:

This spiral-flow type two-phase filter comprises housing, and housing is provided with import and outlet, is provided with and is prepended to the filter screen of outlet and the rotation baffle between filter screen and import in described housing. The effect of described filter screen is impurity in liquid barrier before liquid enters outlet, prevents that impurity from entering outlet. The effect of described rotation baffle is after liquid enters housing, to make liquid rotate, thereby makes lighter floccule in the center motion of liquid stream.

Object of the present invention can also be achieved through the following technical solutions:

The entrance point of described housing is provided with sewage draining exit. The effect of described sewage draining exit is compared with the instant removing of heavy seeds in realizing housing in not out-of-work situation. The entrance point of described housing refers to the housing of import place end. Described inner walls is circular, and rotation baffle is fixed on body and originates in entrance location, import and inner walls out of plumb. This housing circular inner wall, the rotation initial setting position of baffle and only rely on liquid flow, housing circular inner wall and rotation baffle to form the state mobile compared with maelstrom when import is oblique or the version that tangentially enters housing easily makes liquid enter in housing, have advantages of simple in structure, save the energy and eddy flow space large. Rotation baffle originates in entrance location and refers to that rotation baffle originates in the position of the sagittal plane of import place housing. Described inner walls is circular, and rotation baffle comprises multiple stators. Described rotation baffle can form rotation baffle gap by multiple stators, is conducive to guiding, actuates liquid formation eddy flow. The port of export of described housing is provided with the mechanism for assembling-disassembling of filter screen. The effect of described mechanism for assembling-disassembling is to facilitate filter screen dismounting clean. The port of export of housing refers to the housing of outlet place end. Described filter screen is provided with tapered end. The effect of described tapered end is to reduce liquid eddy flow resistance, and stops that the lighter cotton-shaped impurity in the middle of eddy flow passes through filter screen. Described inner walls is circular, rotation baffle is fixed on body and originates in entrance location, import and inner walls out of plumb, described rotation baffle comprises multiple stators, the projection of multiple stators in the sagittal plane of housing is uniformly distributed along the periphery of this plane. Rotation baffle can form rotation baffle gap by multiple stators, can be in playing in guide housing liquid and forming eddy flow, and also help and reduce it sedimentation compared with heavy seeds is hindered. The projection of multiple stators in the sagittal plane of housing is uniformly distributed and is conducive to realize the eddy flow guiding to liquid along the periphery of this plane. Described inner walls is circular, and rotation baffle is fixed on body and originates in entrance location, and the mechanism for assembling-disassembling of described filter screen comprises gland, horizontal depression bar, tommy and pin, between gland and housing, is provided with pad, and filter screen is provided with tapered end. The effect of described gland is that sealing process is played in housing upper end. Described horizontal depression bar and the effect of pin are to be connected with housing, form the supplementary structure of the application of force to gland. The effect of described tommy is that the supplementary structure of the application of force by forming with horizontal depression bar, housing and pin coordinates and screw thread rotation, realizes the application of force to gland or releases power. The effect of described pad is the gap between sealing gland and housing. The filter of this structure have easily realize liquid stream without differential filter, reduce the advantages such as energy loss. Described rotation baffle comprises multiple stators, the projection of multiple stators in the sagittal plane of housing is uniformly distributed along the periphery of this plane, the entrance point of described housing is provided with sewage draining exit, and the valve that is provided with the valve being connected with sewage draining exit, the sand trap cavity being connected with this valve and is connected with the sand trap cavity other end. The effect of the described valve being connected with sewage draining exit, the sand trap cavity being connected with this valve, the valve composition structure that is connected with the sand trap cavity other end is to realize removing compared with heavy seeds sedimentation in sand trap cavity under the state that does not stop filter work. The filter interior structure of this structure has advantages of easy-to-use, blowdown fast and easy simple in structure, is conducive to make filter maintenance normal operating conditions in long-time. Described inner walls is circular, rotation baffle comprises multiple stators, the mechanism for assembling-disassembling of described filter screen comprises gland, horizontal depression bar, tommy and pin, between gland and housing, be provided with pad, filter screen is provided with tapered end, described housing is provided with sewage draining exit, and the valve that is provided with the valve being connected with sewage draining exit, the sand trap cavity being connected with this valve and is connected with the sand trap cavity other end. The filter interior structure of this structure have simple in structure easy-to-use, easy to clean fast, can remove in time compared with heavy seeds and make filter advantage such as maintenance normal operating conditions in long-time.

Beneficial effect of the present invention: due to the simple structure of the housing by described, filter screen and rotation baffle, after making liquid enter housing, can form rotating vortex, produce centrifugal force, make cotton-shaped impurity accumulate in liquid stream center, concentrate in the middle of filter screen, thereby reduced the flocculent substance in liquid to the large-area occlusive effects of filter screen; And by the mechanism for assembling-disassembling of sewage draining exit, valve, sand trap cavity, filter screen is set on housing, can realizes under not out-of-work state impurity screening is conveniently cleared up, improve the data precision of measuring instrument etc. So that the present invention compared with the existing technology has is simple in structure, easy to use, keep the advantages such as normal operating conditions in can be for a long time.
