Embodiment 1

[0040] This preferred embodiment discloses an inner cylinder of a vertical oil separator. Such as Figure 2 to Figure 4 As shown, the inner cylinder 1 includes a hollow cylinder wall 11 whose diameter gradually increases from the top to the bottom. Air outlet holes 13 are evenly opened at the bottom edge of the cylinder wall 11 . The air outlet holes 13 are evenly distributed, and the number is preferably 3 to 20, preferably 8.

[0041] If the opening area is too high, the separation efficiency of the inner cylinder will be reduced, and if it is too low, the pressure drop of the inner cylinder will be increased. Therefore, the height of the opening area needs to be designed according to the usage conditions. Preferably, the height of the outlet hole 13 is h, the overall height of the inner cylinder 1 is H, and 0.1H≤h≤0.5H; more preferably, h=0.3H.

[0042] The area of ​​the air outlet hole 13 will also have an impact on the use of the oil separator. Specifically, if the ar...

Embodiment 2

[0044] This preferred embodiment discloses an inner cylinder of a vertical oil separator, the structure of which is basically the same as that of the first preferred embodiment. The difference is that if Figure 5 with Image 6 As shown, the inner cylinder 1 includes a truncated cone-shaped cylinder wall 11 , and a top guide device 12 is formed on the top edge of the cylinder wall 11 extending upward and inward.

[0045] The slope of the top guide device 12 is larger than that of the cylinder wall 11 to ensure that the oil droplets fall more smoothly. Air outlet holes (not shown in the figure) are uniformly opened at the bottom edge of the cylinder wall 11, and the shape and area of ​​the air outlet holes are equal to those of the preferred embodiment 1.

Embodiment 3

[0047] This preferred embodiment discloses an inner cylinder of a vertical oil separator. Such as Figure 7 with Figure 8 As shown, the cylinder wall 11 includes a straight cylindrical wall body 14, which extends upward and inward at the top edge of the wall body 14 to form a top deflector 12, and extends downward at the bottom edge of the wall body 14 to form a Bottom deflector 15. The umbrella-shaped bottom guide device 15 can be fully welded on the shell on the area in contact with it, so as to enhance the strength of the inner cylinder.

Abstract

A vertical oil separator inner drum, the inner drum (1) comprising a hollow drum-shaped drum wall (11), the drum wall (11) diameter at least partially gradually increasing from a top portion to a bottom portion thereof. The vertical oil separator inner drum having such an inclined structure ensures that oil droplets fall more smoothly and rapidly, and has a wide range of application. Further, the distance between the outer wall and cover inner wall of the vertical oil separator inner drum gradually changes, causing the sectional area of a fluid flow to change, controlling the overall flow speed of the fluid, and thereby further improving oil separator efficiency while avoiding an increase in pressure loss. Further disclosed is a vertical oil separator comprising the vertical oil separator inner drum and a method of arranging the vertical oil separator.

Description

technical field [0001] The invention relates to the field of oil separators, in particular to an inner cylinder of a vertical oil separator, a vertical oil separator equipped with the inner cylinder of the vertical oil separator, and an arrangement method of the vertical oil separator. Background technique [0002] In the operation of refrigeration equipment, the oil separator is used to separate the lubricating oil from the refrigerant vapor discharged from the compressor. Lubricating oil is in the form of small oil droplets or oil mist in the exhaust. [0003] The existing oil separator structure such as figure 1 As shown, the inner cylinder 1 arranged in the housing 2 is in the shape of a straight cylinder. The main defects include: 1. The fluid velocity is slow, which leads to a small fluid inertia; 2. The oil drop does not fall smoothly. Contents of the invention [0004] One object of the present invention is to propose a vertical oil separator inner cylinder that...
