Abstract
A rotating membrane tube suitable for membrane deaerators is provided, which comprises a rotating membrane tube body and through holes arranged horizontally along the external wall of the rotating membrane tube body. The through holes are non-circular ones with a declined angle and along the tangential direction of the external wall of the rotating membrane tube body. The utility model has the advantages that the rotating membrane tube body is arranged into two sections of tube bodies and a plurality of continuous mangers opened evenly along the tangential direction on the junction surface of one of the tube body; through holes are formed through consolidation of the two sections of tube bodies, therefore realizes that the through holes arranged evenly along the external wall of the rotating membrane tube body horizontally are opened in the tangential direction and are provided with declined angles, improves the rotating membrane quality formed the liquid entering the rotating membrane tube, causes the liquid membrane thin and rotary speed fast and removes rupture of membranes.
Description
Technical field:
The utility model relates to a kind of oxygen-eliminating device, relates to a kind of rotation membrane pipe that is applicable to membrane deaerator specifically.
Background technology:
Membrane deaerator generally is used for industrial and mining enterprises and power plant.The structure of rotation membrane pipe wherein (or claiming to revolve the film generator tube) mostly is the round shape through hole in the uniform setting of a circular tube external wall upper edge level, for the liquid in this hole enters pipe can be flowed downward to form moisture film along the inwall rotation, then requiring described through hole to should be along rotation membrane pipe tangentially is provided with, it is the smaller the better to cut angle, but because the rotation membrane pipe outer wall is cylindrical, it is unequal that processing difficulties and make is opened in through hole on the existing rotation membrane pipe tube wall tangential angle big and each through hole that cuts angle, and causes rotation membrane pipe inward turning mould of poor quality and the rupture of membranes phenomenon arranged.
Summary of the invention:
The purpose of this utility model provides a kind of rotation membrane pipe that is applicable to membrane deaerator with regard to being at the deficiency that above-mentioned prior art exists.
For achieving the above object, the utility model can be realized by following technique measures:
The utility model comprises the rotation membrane pipe body and along the through hole of the uniform setting of described rotation membrane pipe body outer wall level, and described through hole is for along described rotation membrane pipe body outer wall tangential direction and have the non-round tube hole of a tilt angled down.
Described through hole is the downward taper hole of tapering, and described rotation membrane pipe body is by two sections fixed forming of body, tangentially uniformly on one section body faying face therein has a plurality of grooves.
Advantage of the present utility model is to adopt described rotation membrane pipe body to be set to two sections bodys, and tangentially uniformly on one section body faying face therein have a plurality of grooves, and with the fixed one of described two bodys to form described through hole, thereby realized offering with tangential direction and having a downward inclination angle along the through hole of the uniform setting of described rotation membrane pipe body outer wall level, improved and entered the formed film quality that revolves of liquid in the rotation membrane pipe, made its liquid film thin and rotary speed is fast and eliminated the rupture of membranes phenomenon.
Description of drawings:
Fig. 1 is a perspective view of the present utility model.
The specific embodiment:
The utility model describes in further detail below in conjunction with accompanying drawing:
As shown in the figure, the utility model comprises the rotation membrane pipe body, with through hole along the uniform setting of described rotation membrane pipe body outer wall level, described through hole is for along described rotation membrane pipe body outer wall tangential direction and have the non-round tube hole of a tilt angled down, described through hole is the downward taper hole of tapering, described rotation membrane pipe body is to be formed by fixed by two sections bodys 1,2, tangentially uniformly on a body 2 faying faces 3 therein has a plurality of grooves 4.
Claims (3)
