(54) FLUID SEPARATOR

Ibregregheniya refers to the field of technical equipment, namely, to the liquidity of the liquid refrigerant in compression kopipipnyh installations.

Liquid separators are known primarily for a compression refrigeration installation, comprising a housing with inlet and outlet nozzles, the latter of which is made U-shaped with a cushion and ascending branches and is located inside the housing ij. The disadvantage of such liquid separators is the possibility of a large amount of liquid refrigerant getting into the compressor mainly during the start-up period, which can lead to a hydraulic shock and compressor failure.

The aim of the invention is to increase the operational safety of a compression refrigeration unit by preventing a large amount of liquid from entering the compressor, preferably during the start-up period. This is achieved in that the ascending branch of the U-junction pipe of the proposed model is inserted vertically with a jugger and a tube, the upper end of which is located above the liquid level, and the lower one is lowered into the liquid pool.

The drawing schematically shows the described fluid separation.

The liquid separator contains a core, start-up 1, in which a U-shaped part 2 of the outlet nozzle 3 is embedded, a U-shaped part 2 is inserted vertically into the cutter 4, one end of which is located in the output nozzle 3 above the liquid level in the housing 1 and the other end lowered to the bottom of the case. Separate also provided with an inlet 5.

The geometrical dimensions of the housing 1 and the pipes 3 and 5 provide the specified separation of the liquid refrigerant, and the flow area of the tube 4 - a given leakage into the outlet of the pipe 3.

The liquid refrigerant separator works as follows.

When the compressor is running, the vapor with the liquid refrigerant enters through the inlet 5 into the housing 1. By reducing the speed of the vapor, the vapor is removed from the liquid and enters the u-shaped part 2 of the outlet pipe3. The moving vapor pairs in the knee, where the tube 4 is inserted, create an obstructed vortex, and a predetermined portion of the liquid bubble from the lower part of the housing 1 enters the vertical pipe through the tube 4. When the compressor is stopped, the flow of the liquid in the fluid separation stops. The tube 4 is zapapnatsya liquid kpadagentom possible level of liquid in the housing 1. The end of the tube 4 located above the level of liquidity in the body 1, prevents the filling-on, different parts 2 liquid kpadagentom. When the compressor is started up, only a part of liquid liquid flows to the output bar 3, and the tube 4 decreases. The decrease in the amount of liquid entering the compressor in the estimated structure depends on the ratio of the volumes of the tube 4 and the i-shaped part 2, which increases with increasing performance of the liquid separator - refrigerant. The described liquid chlal agent separator reduces the amount of
