Example Embodiment
[0038] Example 1:
[0039] like Figure 1 to Figure 4 As shown in the figure, a jet-type heavy oil-mixed dilute mixing tool comprises an outer cylinder (1), a wing plate (2), an upper plug (41), and a lower plug (42), the outer cylinder (1) ) is provided with a thin oil port (5), and both ends are provided with a first connecting thread (11) and a second connecting thread (12); the wing plate (2) is provided with jet holes (3), two The wing plate (2) with an included angle α together with the upper plug (41) and the lower plug (42) forms a jet cavity. There are three groups of the jet chambers, which are evenly distributed and fixed on the inner wall of the outer cylinder (1), and are arranged in parallel with the geometric centerline (a) of the outer cylinder (1); and the jet holes (3) of the jet chamber ) The total area is not greater than the area of the thin oil port (5). Wherein, the upper plug (41) and the lower plug (41) are of conical surface structure; the thin o...
Example Embodiment
[0042] Embodiment 2:
[0043] like Figure 5As shown, this embodiment is basically the same as the first embodiment. The difference lies in that: the jet chamber is composed of two mutually parallel wing plates (2) (wing plate opening angle: α=0°), and the geometric center line between the jet chamber and the outer cylinder (1) (a) It is arranged in a spiral shape, and the value range of the helix angle β of the wing plate is: 45°≦β≦75°. The helix angle of the thin oil port (5) is the same as the helix angle β of the wing plate.
[0044] The existence of the helix angle β of the wing plate can form a circumferential rotation and cause a certain degree of turbulence in the process of returning the heavy oil or mixed oil, which is beneficial to further improve the mixing uniformity of the oil.
Example Embodiment
[0045] Embodiment three:
[0046] like Image 6 As shown, this embodiment is basically the same as the first embodiment. The difference lies in that: the jet cavity is helically arranged with the geometric centerline (a) of the outer cylinder (1), and the value range of the helix angle β of the wing plate is: 45°≦β≦75°; The helix angle of the oil port is the same as the helix angle β of the wing plate. Moreover, there is no direct contact between the jet cavities, that is, the heavy oil or mixed oil channels (jet mixing regions) separated by the jet cavities communicate with each other.
[0047] In this embodiment, each blending area is connected, and it is more suitable under the working condition that the viscosity of the heavy oil is relatively low, or under the condition that a secondary blending process is required during the lifting of the heavy oil. The fluidity of the oil with better fluidity can be further improved by the solution adopted in this embodiment, so as ...
