Problems solved by technology

[0003] This method of smooth side walls and only relying on gravity to return oil mainly has the following disadvantages: 1. When a large number of oil droplets form a thick oil film on the wall surface, the oil film is easily washed by the air flow, causing it to rupture; It takes a long time for the drop to fall only by gravity, and it is easy to be entrained and mixed by the air flow during the falling process, and the oil separation effect is poor

Embodiment 1

[0030] This preferred embodiment discloses an inner cylinder of a vertical oil separator. The inner cylinder is rolled from the wall plate 1, such as figure 1 and figure 2 As shown, oil guide grooves 11 or oil guide ribs 12 are provided on the inner and outer sides of the wall plate 1 of the inner cylinder; the oil guide grooves 11 and / or oil guide ribs 12 are at least partially along the The outer side of the wall plate 1 is inclined downward.

[0031] The oil guide groove 11 has adsorption function, which can improve the ability of the oil film to resist fluid erosion, reduce the possibility of the fluid impacting the oil film on the wall surface, and then take away the oil droplets, increase the speed of the oil film flowing down the wall surface, and improve the oil return capacity of the oil separator . The oil guide ribs 12 are sandwiched with the side of the wall plate 1 to form a concave angle structure, and the two oil guide ribs 12 are sandwiched with the side of...

Embodiment 2

[0039] This preferred embodiment discloses a casing of a vertical oil separator. The housing is rolled from wall plates, and oil guide grooves and / or oil guide ribs are provided on the inner side of the wall plates of the housing; the oil guide grooves and / or oil guide ribs are at least partially Slope down the inside side of the siding. An oil guide plate is arranged at the end of the oil guide groove and / or the oil guide rib.

[0040] The shape and size of the oil guide groove and the oil guide rib are the same as those in the first preferred embodiment.

Embodiment 3

[0042] This preferred embodiment discloses a vertical oil separator. Such as Figure 7 As shown, the vertical oil separator may only include the inner cylinder 2 as described in the first preferred embodiment, may only include the housing 3 as described in the second preferred embodiment, and may also include the same as described in the first preferred embodiment The inner cylinder 2 and the housing 3 as described in the second preferred embodiment, the inner cylinder 2 is arranged in the housing 3 .

[0043] Regardless of the number of oil-guiding grooves 11 and oil-guiding ribs 12 on the wall plate 1 is large or small, the number of oil-guiding plates arranged at the ends of the oil-guiding grooves 11 and / or oil-guiding ribs 12 should not be less than four, Otherwise, it will not be able to prevent the oil droplets from falling directly. At the same time, in order to avoid excessively increasing the pressure drop, the number of oil guide plates should not exceed ten.

Abstract

The invention discloses an internal cylinder and a shell of a vertical oil separator and the vertical oil separator and belongs to the field of oil separators. The internal cylinder and the shell of the vertical oil separator and the vertical oil separator are designed in order to solve the problem that oil film in an existing structure is prone to cracking. The inner lateral face and / or the outer lateral face of a wallboard of the inner cylinder of the vertical oil separator are / is provided with an oil guide groove and / or an oil guide convex rib; at least part of the oil guide groove and / or the oil guide convex rib inclines downwards along the outer lateral face of the wallboard. The vertical oil separator comprises the inner cylinder and / or the shell, and the inner cylinder is arranged inside the shell. The stability of the oil film of the wall surface is enhanced through the inner cylinder and the shell of the vertical oil separator, and possibility that the oil film is scoured by gas and cracks is reduced. The vertical oil separator is good in oil separation effect and reduces the probability of backmixing of airflow with oil drops.

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 casing of the vertical oil separator, and a vertical oil separator including the inner cylinder and / or the casing. Background technique [0002] The oil separator is a device that removes the mixed oil in the refrigerant, and also has the function of collecting the filtered oil to the bottom oil pool. The inner cylinder of the existing vertical oil separator and the sides of the housing are all smooth surfaces, and the effect of gravity (gravity dripping) is used to collect oil droplets. [0003] This method of smooth side walls and only relying on gravity to return oil mainly has the following disadvantages: 1. When a large number of oil droplets form a thick oil film on the wall surface, the oil film is easily washed by the air flow, causing it to rupture; It takes a long time for the drop to fall only by gravity, and it is easy to...
