An air inlet is arranged at the lower right side of the outer end of the cooling cylinder, and an air outlet pipe is fixedly installed at the upper end of the cooling cylinder. A temperature recovery system is installed inside the cooling cylinder for pre-treating the air just entering the cooling cylinder and for heating and recovering the gas cooled by the evaporation system.

[0009] The temperature recovery system includes a baffle ring and a temperature recovery heating pipe. A plurality of baffle rings are fixedly installed on the inner wall of the cooling cylinder; a plurality of air holes are arranged on the outer ring of the baffle ring; a plurality of temperature recovery heating pipes are fixedly installed on the right side of the inner part of the cooling cylinder, and the upper and lower ends of the temperature recovery heating pipes are fixedly installed on the right side of the baffle rings at the upper and lower ends; the diameter of the air holes arranged on the baffle ring between the uppermost baffle ring and the lowermost baffle ring is larger than the air holes on the uppermost baffle ring and the lowermost baffle ring;

[0011] Furthermore, the temperature recovery system also includes a baffle, a baffle placed vertically and horizontally is fixedly installed in the middle of the inner top of the cooling cylinder, and baffles placed vertically and horizontally are also symmetrically fixedly installed on the front and rear sides between adjacent baffle rings;

[0012] Furthermore, the baffle is made of heat-insulating material;

[0013] Furthermore, a through groove is provided on the baffle between the topmost baffle ring and the lower adjacent baffle ring;

[0014] Furthermore, the retaining rings are evenly distributed in a linear array along the height direction inside the cooling cylinder at equal intervals;

[0015] Furthermore, the evaporation system includes a fixed cylinder, an evaporation core connecting pipe, a drain pipe and an evaporation core, the fixed cylinder is fixedly mounted on the inner ring of the plurality of retaining rings; an evaporation system inlet is arranged at the lower left side of the outer end of the fixed cylinder; an evaporation system outlet is arranged at the left side of the upper end of the fixed cylinder; the upper ends of the evaporation core connecting pipe and the drain pipe are fixedly mounted on the bottom end of the fixed cylinder and are connected to the evaporation core; and the lower ends of the evaporation core connecting pipe and the drain pipe pass through the bottom of the cooling cylinder; the evaporation core is fixedly mounted inside the fixed cylinder;

[0033] Embodiment 1: In some embodiments, please refer to the drawings of the specification Figure 1-Figure 8 A refrigerated air dryer comprises a cooling cylinder (1), an air outlet pipe (3), a temperature recovery system (4) and an evaporation system (5); an air inlet (2) is arranged at the lower right side of the outer end of the cooling cylinder (1); the air outlet pipe (3) is fixedly mounted at the upper end of the cooling cylinder (1); a temperature recovery system (4) is installed inside the cooling cylinder (1) for pre-treating the air just entering the cooling cylinder (1) and for heating and recovering the gas cooled by the evaporation system (5);

[0034] The temperature recovery system (4) comprises a baffle ring (41), a temperature recovery heating tube (43) and a baffle plate (44); a plurality of baffle rings (41) are fixedly installed on the inner wall of the cooling cylinder (1); the baffle rings (41) are evenly distributed in a linear array at equal intervals in the height direction inside the cooling cylinder (1); a plurality of air holes (42) are arranged on the outer ring of the baffle ring (41); the air holes (42) are evenly distributed in a circular array at equal intervals on the outer ring of the baffle ring (41); a baffle plate (44) is fixedly installed in the middle of the inner top end of the cooling cylinder (1), and baffle plates (44) are also symmetrically fixedly installed on the front and rear sides between two adjacent baffle rings (41); a through hole is arranged on the baffle plate (44) between the top baffle ring (41) and the adjacent baffle ring (41) at the lower side. The baffle (44) divides the interior of the cooling cylinder (1) into two parts, the left and right parts, and the baffle (44) is used to isolate the gas from communicating with each other in the left and right parts; the left half of the baffle (44) is set as a gas flow area, and the right half of the baffle (44) is set as a pre-treatment heating area; the baffle (44) is made of heat-insulating material; a plurality of temperature recovery heating pipes (43) are fixedly installed on the right side of the interior of the cooling cylinder (1), and the upper and lower ends of the temperature recovery heating pipes (43) are fixedly installed on the right side of the upper and lower baffle rings (41); the diameter of the air vents (42) provided on the baffle ring (41) between the uppermost baffle ring (41) and the lowermost baffle ring (41) is larger than the air vents (42) on the uppermost baffle ring (41) and the lowermost baffle ring (41), so as to accelerate the circulation of air.

[0035] An evaporation system (5) for evaporative cooling of air is also installed inside the cooling cylinder (1), and the evaporation system (5) is arranged inside the temperature recovery system (4).

[0036] In the present invention, air enters the right side of the interior of the cooling cylinder (1) through the air inlet (2).

[0038] In the present invention, when the air flows to the evaporation system inlet (52), it enters the interior of the fixed cylinder (51) through the evaporation system inlet (52), and then the evaporation core (56) works to evaporate and cool the air, and the gas after evaporation and cooling is discharged through the evaporation system outlet (53). The drain pipe (55) can discharge the water generated during evaporation out of the fixed cylinder (51).
