[0022] Referring to Figure 1The application provides a gas-liquid separation dryer, which comprises a tank body 1, a gas-liquid separation chamber 100 arranged in the tank body 1 and a drying chamber 200 arranged below the gas-liquid separation chamber 100; a gas outlet 11 communicating with the gas-liquid separation chamber 100 is arranged on the top of the tank body 1, and a liquid outlet 12 communicating with the drying chamber 200 is arranged on the bottom of the tank body 1; a gas-liquid mixture inlet 13 communicating with the gas-liquid separation chamber 100 is further arranged on the side wall of the tank body 1.

[0023] The mixed refrigerant enters the gas-liquid separation chamber 100 from the gas-liquid mixture inlet 13, the gaseous refrigerant is discharged from the gas outlet 11, and the liquid refrigerant enters the drying chamber 200 downward.

[0024] The drying chamber 200 is provided with a filter screen 14, and a water removal layer 15 is arranged above the filter screen 14; the water removal layer 15 is provided with molecular sieves.

[0025] The water in the liquid refrigerant is removed by the molecular sieves in the water removal layer 15, and the impurities mixed in the liquid refrigerant are blocked on the filter screen 14 and then flow out from the liquid outlet 12.

[0026] The application sets the drying chamber 200 below the gas-liquid separation chamber 100, integrates the gas-liquid separation and drying functions into the same tank body, replaces the drying filter, and simplifies the composition structure and manufacturing process of the refrigeration system. Meanwhile, the volume of the chamber for storing the refrigerant is reduced, and the filling amount of the whole refrigeration system is reduced.

[0027] Referring to Figure 2 As an embodiment, the water removal layer 15 of the application comprises two water removal cylinder layers stacked one above the other; each water removal cylinder layer comprises a plurality of water removal cylinders 3 arranged in parallel; the water removal cylinders 3 are filled with molecular sieves, and the cylinder walls of the water removal cylinders 3 are uniformly provided with liquid outlet holes;

[0028] The arrangement of the two water removal cylinder layers increases the thickness of the water removal layer 15 and optimizes the water removal effect. Better, the two water removal cylinder layers are cross-stacked, so that the refrigerant cannot leak through the gap between the two water removal cylinders 3.

[0029] Preferably, the water removal cylinders are made of metal mesh, and the number of liquid outlet holes is large, so that the passing rate of the liquid refrigerant is high.

[0030] In order to make the liquid refrigerant uniformly disperse from each water removal cylinder 3, as a preferred mode, a flow distribution plate 2 is arranged between adjacent water removal cylinders in the lower water removal cylinder layer; the liquid refrigerant is uniformly distributed to each water removal cylinder 3 through the flow distribution plate 2, so that the utilization rate of the molecular sieves in each water removal cylinder 3 is improved.

[0031] Better, a plurality of liquid passing holes are uniformly arranged on the flow distribution plate 2, so that the accumulated liquid can be quickly distributed to the water removal cylinders 3 on both sides.

[0032] Combination Figure 3 A first supporting cylinder strip 21 is arranged between the two water removal cylinders 3 in the upper and lower layers and in contact with each other; the water removal cylinder 3 in the upper layer is placed on the first supporting cylinder strip 21, and the water removal cylinder 3 in the lower layer can be taken out or placed in without affecting the assembly or maintenance. The first supporting cylinder strip 21 is fixed on the flow distribution plate 2 by a supporting rod 23.

[0033] In order to smoothly take out or place the water removal cylinder 3, the first supporting cylinder strip 21 is embedded with guide balls 22 on the side surface facing the water removal cylinder 3.

[0034] Referring to Figure 4 More preferably, the side bottom of the water removal cylinder 3 in the lower layer is provided with a second supporting cylinder strip 24; the second supporting cylinder strip 24 is fixed on the flow distribution plate 2 by a supporting rod 23; and the second supporting cylinder strip 24 is embedded with guide balls 22 on the side in contact with the water removal cylinder 3.

[0035] The first supporting cylinder strip 21 and the second supporting cylinder strip 24 respectively support the water removal cylinders 3 in the upper and lower layers, so that each water removal cylinder 3 can be independently taken out or placed, facilitating maintenance and replacement.

[0036] In summary, the application provides a gas-liquid separation dryer, which integrates the functions of gas-liquid separation and drying into the same tank by arranging a drying chamber below the gas-liquid separation chamber, thereby replacing the drying filter and simplifying the composition structure and manufacturing process of the refrigeration system. At the same time, the volume of the chamber for storing refrigerant is reduced, and the filling amount of the entire refrigeration system is reduced.
