Abstract

A filtering oil separator belongs to a device in a compressor refrigeration system capable of separating the lubricating oil from the refrigerant. The filtering oil separator comprises a cylinder shell, an air-in pipe, an inlet filter screen, an air-out pipe, an air outlet filter screen, a separating board, an inertial damping filter structure, a baffle, a floating ball valve, a back oil pipe and a strong magnetic element. Multiple layers and different numbers of stainless steel wire meshes are combined according to a certain order to constitute the inlet filter screen and the air outlet filter screen, a proper distance exists between the filter screen layers and the inertial damping filter structure is mounted between a lower part of the separating board and the baffle. The art measures are in favor of precipitation, condensation and accumulation of the lubricating oil and greatly improve the oil separation efficiency. The strong magnetic element mounted at the bottom of the cylinder shell is capable of absorbing and eliminating the ferrous abrasive dust particles in the lubricating oil which is separated and recovered from the refrigerant.

Description

The filtering type oil eliminator

Affiliated technical field

The filtering type oil eliminator that the utility model relates in a kind of compressor refrigeration system from cold-producing medium separate lubricant and reclaimed.

Background technology

The pattern of oil eliminator is decided with the size of refrigerating capacity and the cold-producing medium of use in the refrigeration system, in freon refrigeration system, often use the filtering type oil eliminator at present, it is made up of barrel shell, air inlet pipe, intake screen, escape pipe, gas outlet filter screen, dividing plate, ball-cock assembly, baffle plate, oil return pipe etc., its intake screen and gas outlet filter screen all are rolled into two layers of tubular construction by 60 order woven wires, a welding and an end closure form, the barrel shell internal partition has oblong openings, connects air inlet area and goes out the gas area.

When the gases at high pressure of compressor discharge enter oil eliminator, the lubricating oil that compressor air-discharging is carried secretly relies on the deceleration of exhaust, flow direction variation to separate with the filtration of braid fabric, the lubricating oil of separating accumulates in the oil eliminator bottom, when lubricating oil gathers certain altitude, ball-cock assembly is opened, lubricating oil is sent back in the oil container of compressor crankcase or system again, thereby guarantees that compressor runs well.

This oil separator structure is simple, and is easily manufactured, but separative efficiency is not high enough, and the lubricating oil of fully not separating enters heat-exchange system with cold-producing medium, influences heat exchange effect; In the compressor operating process, because the mutual friction between parts, produce some metal filings particulates, this particulate is difficult for being removed by system's middle filtrator, carry current downflow secretly or be adsorbed at refrigerant vapour stream, the EVAC control element, or with the lubricating oil backflow compressor crankcase of separating in the oil eliminator, influence system's refrigeration and compressor life-span, the abrasive dust of iron particularly, easily gather, big to system's refrigeration and life-span influence, but existing filtering type oil eliminator is not removed the function of the abrasive dust particulate of iron from separate the lubricating oil that reclaims.

Summary of the invention

Not high enough in order to overcome existing filtering type oil eliminator separative efficiency, and the deficiency that can not remove the abrasive dust particulate of iron, the utility model provides a kind of filtering type oil eliminator, this oil eliminator separative efficiency significantly improves, and the irony abrasive dust particulate in the lubricating oil that the energy adsorbing separation is come out reduces the influence of this particulate to system to greatest extent.

The technical scheme that its technical problem that solves the utility model adopts is: intake screen is made up of the stainless steel metal silk screen of multilayer different meshes, and its from inside to outside the order number of each layer woven wire successively increase, the outlet filter screen also is made up of the stainless steel metal silk screen of multilayer different meshes, its from outside to inside the order number of each layer woven wire successively increase, they separately in, in, any two-layer adjacent filter screen in outer three layers, the numerical value that the internal diameter of outer filter is more suitable than adjacent inner layer filter screen external diameter big, during with assurance air communication screen pack, between the filter mesh layer of the main position of gas communication, suitable spacing is arranged, form three-dimensional mazy passage; The inertia damping filter mechanism is set between baffle plate and dividing plate, inertial filter mechanism is a rectangular plate-shaped member, its width dimensions is greater than height dimension, the inertia damping filter mechanism is made up of framework and the screen pack group that is fixed on the framework, its screen pack group, metal lath by multiple layer metal silk screen and the more one decks of respective numbers combines, and its two sides respectively has the layer of metal expanded metals to support, and uses the layer of metal expanded metals at interval between middle woven wire is two-layer; In oil eliminator barrel shell bottom, be provided with and under HTHP, work and to be difficult for cooled dose of strong magnetic element that corrodes with lubricating oil.

The utility model is compared with existing oil eliminator, three place's filter mechanisms of the present utility model are strengthened the filter capacity that filter mechanism forms with association mechanism actings in conjunction such as diffusion, interception, collisions because the special construction of screen pack makes gas channel S-shaped, the pressure loss is little, and filter effect is strong; The inertia damping filter mechanism of setting up, the utility model has been Duoed than existing oil eliminator to be filtered together, and the centrifugal inertial force that gas is directed downwards when flowing through the inertia damping filter mechanism with the gravity acting in conjunction, makes less lubricating oil drop obtain separating; Strong magnetic element in that oil eliminator barrel shell bottom is provided with can adsorb the irony abrasive dust that compressor air-discharging is brought oil eliminator into.

The utility model beneficial effect is: compare with existing filtering type oil eliminator, the oil of the utility model filtering type oil eliminator separates efficient and obviously improves, and has had the function of removing the abrasive dust particulate of iron with the method for absorption from separate the lubricating oil that reclaims again.
