Abstract

The utility model discloses an oil separator, which belongs to the technical field of central air-conditioning. The oil separator adopts a horizontal barrel; the barrel is arranged on a base; a refrigerant outlet is arranged at the upper part of the barrel; a connecting pipe is arranged at the lower part of the barrel; an oil outlet is arranged beside the connecting pipe; a drain outlet is arranged on the lower side of the connecting pipe; a refrigerant inlet is arranged on a front end cover of the barrel; an air intake baffle is arranged at the upper part in the barrel; an oil separating component integrally has a square structure; a plurality of refrigerant outlet holes are arranged on left, right and lower sides of a refrigerant inlet pipe; steel screens are respectively arranged on upper, lower, left and right sides of the refrigerant inlet pipe; a wire mesh block is arranged between each two steel screens on upper and lower sides respectively; a wire mesh block is arranged between each steel screen and a baffle at the periphery of the steel screen respectively in directions of left and right sides; and a pipe inlet baffle is arranged at the rear end of the refrigerant inlet pipe. The oil separator can effectively separate refrigeration oil brought out by refrigerant from the refrigeration oil, so as to ensure that the refrigeration oil can return a compressor in time, to prevent the compressor from losing oil, the efficiency of oil and refrigerant separation is high, and the separation efficiency reaches 99.9 percent.

Description

Oil eliminator

Technical field

The utility model belongs to the central air-conditioning technical field, is specifically related to water-cooled screw compressor group.

Background technology

The conventional central air-conditioning adopts water-cooled vortex unit, the adapted vertical oil separator, the space is limited, screen pack is provided with thin, and the number of plies is limited, mainly separates by centrifugal force, flow velocity is inhomogeneous, divide oily weak effect, the oil of dishing out in the compressor can not in time be separated by oil content and follow the high pressure refrigerant and participated in systemic circulation, and above-mentioned deficiency makes unit reduce refrigeration (heat) efficient.

Summary of the invention

The purpose of this utility model provides a kind of oil eliminator, and is inhomogeneous to solve the prior art flow velocity, divides oily weak effect, reduced problems such as refrigeration (heat) efficient.

The utility model mainly is made up of body, cylindrical shell, refrigerant import and export, liquid-sighting glass, base, sewage draining exit, oil-out and screen pack, solving the technical scheme that its problem adopts is that oil eliminator adopts horizontal cylinder, cylindrical shell is arranged on the base, the top of cylindrical shell is provided with refrigerant exit, the bottom of cylindrical shell is provided with adapter, take over the side and set out hydraulic fluid port, downside is provided with sewage draining exit, and the refrigerant inlet is set on the drive end bearing bracket of cylindrical shell; At the cylindrical shell internal upper part air-breathing baffle plate is set; Oil content assembly integral body is square structure; The left and right sides on the refrigerant inlet pipe and downside are provided with some refrigerants and portal, above the refrigerant inlet pipe, below, left, the right-hand expanded metal lath that is provided with respectively, up and the below, between per two expanded metal laths the silk screen piece is set respectively, in the left side, the right side both direction, between every expanded metal lath and its outer surrounding baffle silk screen piece is set respectively, the inlet pipe closure plate is set in the rear end of refrigerant inlet pipe.

Adopting good effect of the present utility model is that refrigerant is flowed through behind this oil eliminator, through cascade filtration, and the refrigeration oil that refrigerant can be taken out of, separate effectively, make refrigeration oil in time get back to compressor, in case compressor loses oil, oil and refrigerant separative efficiency height, oil-dividing efficiency reaches 99.9%.Then enter condenser through the refrigerant gas after separating, participate in kind of refrigeration cycle, improved the heat exchange efficiency of refrigeration system greatly.

The specific embodiment

As shown in the figure: oil eliminator adopts horizontal cylinder 4, and cylindrical shell 4 is weldingly fixed on the base, and refrigerant exit 5 is installed on the top of cylindrical shell 4, the bottom welding of cylindrical shell 4 takes over 12, take over 12 sides and set out hydraulic fluid port 11, downside welding sewage draining exit 10 is provided with refrigerant inlet 7 on the drive end bearing bracket 6 of cylindrical shell 4; At cylindrical shell 4 internal upper parts air-breathing baffle plate 3 is installed; Oil content assembly 2 integral body are square structure, the left and right sides on the refrigerant inlet pipe 13 and downside are provided with 18 refrigerants and portal 14, above the refrigerant inlet pipe 13, below, left, the right-hand expanded metal lath 2-2 that is provided with respectively, up and the below, between per two expanded metal lath 2-2 silk screen piece 2-3 is set respectively, on left side, right side both direction, between every expanded metal lath 2-2 and its outer surrounding baffle 2-1 silk screen piece 2-3 is set respectively, inlet pipe closure plate 2-4 is set in the rear end of refrigerant inlet pipe.The silk screen piece all adopts heavy duty detergent in the vapour-liquid screen pack, model is 80-100, and tinsel directly is 0.15, six burst of establishment, material is SUS304, silk screen piece above the refrigerant inlet pipe, below the density of silk screen piece, left side silk screen piece, right side silk screen piece be 400-450kg/m3.(baffle plate thickness the right and left and the centre is different)

During work, refrigerant enters refrigerant inlet pipe 13 with the mixture of oil through refrigerant inlet 7, portal by the some refrigerants that are arranged on the left and right and below on the

refrigerant inlet pipe

13 and 14 to discharge, enter silk screen piece 2-3 by the expanded metal lath 2-2 around it, periphery at and arranged on left and right sides silk screen piece is respectively equipped with baffle plate, refrigerant after the separation passes through the silk screen piece and the expanded metal lath of top at last, is discharged from from refrigerant exit 5 through air-breathing baffle plate 3.Oil after the separation passes through the silk screen piece and the expanded metal lath of below at last, enters to take over 12, flows out from oil-out 11.
