According to the invention, the first partition plate and the second partition plate are arranged in the liquid accumulator, the two partition plates are arranged at intervals along the axial direction, and at least one partition plate covers part of the structure surface of the other partition plate, so that liquid can firstly fall onto the first partition plate positioned on the radial outer side at the radial outer side, the liquid falls downwards below the partition plates through the gap between the two partition plates or the flow channel, and gas upwards enters the upper part of the partition plates through the flow channel or the gap between the two partition plates, so that the path and the liquid path are effectively separated, the problem of poor liquid storage capacity of the liquid accumulator caused by gas-liquid hedging is avoided, the exhaust liquid carrying capacity of the liquid accumulator is greatly reduced, and the risk of liquid impact of a compressor is reduced; according to the innovative design for performing secondary gas-liquid separation of the liquid separator based on the angle of the fluid, the annular channel formed by matching the first partition plate and the second partition plate and the channel of the second partition plate have the functions of exhausting and guiding the liquid respectively, so that the mutual impact between the first partition plate and the second partition plate is avoided, the liquid storage effect of the liquid separator can be improved, the liquid amount entering the exhaust straight pipe of the liquid separator can be reduced, the purposes of reducing the liquid carrying amount of suction gas on the side of a pump body and avoiding liquid impact are achieved, and the effects of shock absorption and noise reduction are achieved.

referring to the attached

drawings

1 and 2, the flow direction of the flow field in the existing liquid separator has a cross phenomenon at the overflow hole of the partition plate, because the partition plate divides the upper cavity and the lower cavity of the liquid separator into two cavities, because the overflow hole has no gas-liquid separation effect, the downward liquid flow of the middle cylinder 7 and the upward air flow of the lower cylinder 8 are caused to generate the opposite impact at the overflow hole, the liquid flow is blown into a large number of small droplets, and then the small droplets are upwards discharged after entering the exhaust straight pipe 6 along with the air flow, so the liquid carrying amount of the suction air at the pump side is increased, and the liquid impact is easily generated.

Example 1, as shown in fig. 3a-5, in some embodiments, the first partition plate 3.1 is located above the second partition plate 3.2, and a gas flow channel is formed between the first partition plate 3.1 and the second partition plate 3.2, and the flow channel 3.5 is formed as a liquid flow channel, so that liquid can flow to the lower side of the second partition plate 3.2 through the flow channel 3.5, and gas can flow to the upper side of the first partition plate 3.1 through the gap between the first partition plate 3.1 and the second partition plate 3.2. The preferred structure form of embodiment 1 of the present invention is that the first partition plate is located above the second partition plate, the gap between the first partition plate and the second partition plate is used for upward gas circulation, and the flow passage formed on the second partition plate is used for downward liquid circulation, so as to form a gas flow passage and a liquid flow passage which are separated from each other, prevent gas-liquid collision, and improve the efficiency of gas-liquid separation.

When liquid flow falls along the inner wall of the cylinder 7 in the liquid separator, the liquid flow falls to the surface of the second clapboard 3.2 under the guidance of the inclined plane of the first clapboard 3.1, and then enters the liquid flow channel 3.5 under the guidance of the inclined plane of the second clapboard 3.2, and falls into the liquid collecting tank 4 along the central axis of the cylinder of the liquid separator under the action of gravity, and due to the impact force of the liquid flow, the air flow is rushed to the wall surface at the bottom of the cylinder 8 under the liquid separator and moves upwards to the position below the first clapboard 3.1 along the wall surface, and then flows to the space of the cylinder 7 through the axial gap between the first clapboard and the second clapboard; meanwhile, the air flow generated by the air suction of the exhaust pipe 6 flows upwards, and is sucked into the exhaust pipe 6 together with the air flow rising in the lower cylinder 8, so that the liquid amount entering the exhaust straight pipe is greatly reduced.

The second partition plate is arranged to comprise the flat-plate-shaped body and the cylindrical portion, so that the function of liquid collecting and storing can be increased through the cylindrical portion, the gas-liquid circulation channels are further separated and isolated, and the gas-liquid separation effect can be further improved.

Referring to fig. 7a-9, the first partition plate is provided with an air guide part 3.6, the second partition plate 3.2 is of a cup-shaped structure, liquid flow falls to the first partition plate 3.1 along the inner wall of the cylinder 7 in the liquid separator, and then the liquid flow is converged into the cup-shaped structure of the second partition plate 3.2, so that the liquid flow state is stabilized, the problem that the liquid flow is blown away is solved, and the discharged air liquid carrying capacity of the liquid separator is further reduced.

Example 3, as shown in fig. 10a-13b, in some embodiments, the first partition plate 3.1 is located below the second partition plate 3.2, and a liquid flow channel is formed between the first partition plate 3.1 and the second partition plate 3.2, and the flow channel 3.5 is formed as a gas flow channel, so that liquid can flow to the lower side of the second partition plate 3.2 through a gap between the first partition plate 3.1 and the second partition plate 3.2, and gas can flow to the upper side of the first partition plate 3.1 through the flow channel 3.5. The preferable structure form of embodiment 3 of the present invention is that the first partition plate is located below the second partition plate, a gap between the first partition plate and the second partition plate is used for directly flowing liquid downwards, and the second partition plate is provided with a flow passage for flowing gas upwards, so that a gas flow passage and a liquid flow passage are formed separately from each other, gas-liquid hedging is prevented, and the efficiency of gas-liquid separation is improved.

In some embodiments, the height of the upper surface of the first partition 3.1 gradually decreases in a radially inward direction; and/or the height of the upper surface of the second partition 3.2 decreases gradually in the radially outward direction.
