The invention relates to the separation of gas-liquid systems and can be applied in various sectors of the industry for cleaning air from oil droplets and moisture, in particular for cleaning compressed air in compressor units.

The purpose of the invention is to improve the separation of moisture and oil from the gas stream.

FIG. 1 schematically shows an inertia water-oil separator; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one.

Water separator consists of a housing 1 with an inlet 2 and outlet 3 nozzles for inlet and outlet of the cleaned air. The end section of the inlet nozzle 2 is made in the form of an open bottom box 4 formed by vertical walls 5, the upper edges of which are connected by a semi-cylindrical shell 6. The lower edges 7 of the vertical walls 5 are bent inwards towards the gas-liquid flow and form inclined chutes 8 in the inner cavity of the box 4 condensate drain. The end wall 9 of the box 4 is inclined toward the inlet 2 and has holes 10 in the lower part with a pipe 11 for condensate drainage.

The inner space of the housing 1 by a vertical hollow partition with walls 12 is divided into a preliminary separation chamber 13 and a final separation chamber 14 communicating with each other. The upper part of the vertical septum is made permeable, the channel 15 between the walls 12 is filled with fibrous filter material 16, for example nylon fiber, in the upper permeable part and. In the vertical walls 12, there are openings 17 for the drain of the separated liquid, at the bottom edge of the box 4.

The outlet nozzle 3 is provided with a duct 18 formed by 1 vertical walls 19, the upper edges of which are connected by a semi-cylindrical shell 20. The lower edges 21 of the vertical walls 19 are bent outward to meet the gas-liquid flow and form assembly chutes 22 outside the chassis 18 for condensate drainage. To gutters 22 prikrydgzny drainage

nozzles 23. The end wall 24 of the box 18 is inclined toward the outlet nozzle 3. Inclined perforated shields 25 and 26 are attached to the walls 24 and 9, which overlap the cross-section of the chambers 13 and 14. At the bottom of the tank is a perforated bottom 27 separating the collection chamber 28 separated liquid from chambers 13 and 14.

At the bottom of the tank there is a port 29 with a valve 30 for discharging the separated liquid.

Water oil works as follows.

The cleaned air containing drops of water and oil enters the duct 4 through the nozzle 2, where, striking the on / clone wall 9, rotates by 90 in the space bounded by the wall 9 and the walls 5. In this case, the large particles of liquid are separated on the wall 9 and flow along it and further along the wall 12 into the chamber 28 of the collection of the compartment of the iranium fluid. At the same time, a film of condensate moving along the nozzle 2 is separated on the walls 5 and flows into the collecting channels 8, from where it is removed through the openings 10 and the nozzles 11 into the channel 15.

After the first rotation by 90, the gas-liquid mixture rotates by 180 relative to edges 7 and enters chamber 13. Separated from this turn, the liquid flows through bottom 27 into chamber 28.

In this way. Hi this stage of inertial separation occurs the separation of large fractions of liquid aerosol. The fine aerosol remaining in the gas stream cannot be caught due to inertial separation and requires additional coagulation. Coagulation takes place with the passage of air through inclined perforated throttle plates 25 and 26 and filter material 16. At the same time, the fine aerosol coagulates by throttling the gas and filtering it through the layer of fibrous material. Partially separated with the aerosol flows along the walls 9 and 24 through the holes 17 into the channel 15, which also receives the liquid separated in the filter material 16.

Air with enlarged particles of liquid aerosol enters the chamber

14, where it wraps around the shell 20 and walls 19. Separated liquid flows into the collecting chutes 22 and is removed through nozzles 23 into the chamber 28.

Further, the air, circumferential edge 21, makes one more turn ND 180 and enters the box 18, in this case there is a final separation of the coagulated aerosol. The air cleared of moisture and oil is removed through the pipe 3, and the separated liquid accumulates in the chamber 28 and is periodically removed through the pipe 29 using the valve 30.

Thus, in the proposed water-oil separator, the inertial separation mechanism is combined with the use of inertial forces of translational and rotational motion and the coagulation mechanism when the gas-liquid mixture passes through the filtering and throttling partitions. Such removal allows to increase the efficiency of air purification from oil and moisture. The proposed water and oil separator is compact and simple in design.
