[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] In the following description, "left", "right", "front", "rear", "upper", "lower" are oriented in the perspective of the front view.

[0030] Embodiment one: in some embodiments, referring to the drawings of the specification Figures 1-8 A refrigeration type air dryer, comprising a cooling cylinder 1, further comprising an air outlet pipe 3, a temperature recovery system 4 and an evaporation system 5, the outer end lower right side of the cooling cylinder 1 is provided with an air inlet 2, and the upper end of the cooling cylinder 1 is fixedly installed with the air outlet pipe 3; the inside of the cooling cylinder 1 is installed with the temperature recovery system 4 for pre-treating the air just entering the inside of the cooling cylinder 1 and heating treatment of the gas cooled after the evaporation system 5;

[0031] The temperature recovery system 4 comprises a baffle ring 41, a temperature recovery heating pipe 43 and a baffle 44, a plurality of baffle rings 41 are fixedly installed on the inner wall of the cooling cylinder 1, and the baffle rings 41 are linearly arrayed and uniformly distributed at equal intervals in the height direction inside the cooling cylinder 1; a plurality of air permeable holes 42 are arranged on the outer circle of the baffle ring 41; the air permeable holes 42 are circumferentially arrayed and uniformly distributed at equal intervals on the outer circle of the baffle ring 41; a baffle 44 horizontally placed in the vertical direction is fixedly installed at the middle of the inner top end of the cooling cylinder 1, and a baffle 44 horizontally placed in the vertical direction is also fixedly installed on the front and rear sides between the adjacent two baffle rings 41; a through groove is arranged on the baffle 44 between the uppermost baffle ring 41 and the adjacent lower baffle ring 41; the baffle 44 divides the inside of the cooling cylinder 1 into two left and right parts, and the baffle 44 is used for isolating the gas communication between the two parts; the left half of the baffle 44 is arranged as a gas flow area, and the right half of the baffle 44 is arranged as a pre-treatment heating area; the baffle 44 is made of heat insulation material; a plurality of temperature recovery heating pipes 43 are fixedly installed on the right side inside 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 baffle rings 41 at the upper end and the lower end; the diameters of the air permeable holes 42 arranged on the baffle rings 41 between the uppermost baffle ring 41 and the lowermost baffle ring 41 are greater than those of the air permeable holes 42 on the uppermost baffle ring 41 and the lowermost baffle ring 41, so as to accelerate the air circulation.

[0032] The inside of the cooling cylinder 1 is further installed with the evaporation system 5 for evaporative cooling of the air, and the evaporation system 5 is arranged inside the temperature recovery system 4.

[0033] In this invention, air enters the interior right side of the cooling cylinder 1 through the air inlet 2. Due to the obstruction of the baffle 44, the air can only flow upward through the vent 42. When it flows to the through groove provided on the baffle 44 between the top baffle ring 41 and the lower adjacent baffle ring 41, the air will flow to the left and enter the gas flow area. Then it flows downward and enters the interior of the evaporation system 5. Subsequently, the evaporation system 5 operates to evaporate and cool the gas that has entered the evaporation system 5. The cooled air is then discharged through the evaporation system 5. The cooled gas then flows downward through the vent 42 provided on the baffle ring 41 and flows downward from the left side of the bottom baffle ring 41. The gas then flows through the vent 42 and flows into the pretreatment heating area from the right side of the bottom baffle ring 41. Subsequently, the reheating heating pipe 43 operates to heat and reheat the cooled gas. The gas flows upward and is finally discharged through the air outlet pipe 3, completing one air compression, cooling and drying process. By setting baffles 44 to separate the interior of the cooling cylinder 1, the gas flow area and the pretreatment heating area are effectively isolated from each other, improving the efficiency of air drying and cooling; and by setting the evaporation system inlet 52 in the gas flow area, the gas after evaporation and cooling is heated, further enhancing the air drying effect of the device.

[0034] Example 2: In some embodiments, such as Figures 4-8 As shown, in a preferred embodiment of this utility model, the evaporation system 5 includes a fixed cylinder 51, an evaporation core connecting pipe 54, a drain pipe 55, and an evaporation core 56. The fixed cylinder 51 is fixedly installed on the inner ring of multiple retaining rings 41. An evaporation system inlet 52 is provided on the lower left side of the outer end of the fixed cylinder 51. An evaporation system outlet 53 is provided on the upper left side of the fixed cylinder 51. The upper ends of the evaporation core connecting pipe 54 and the drain pipe 55 are fixedly installed on the bottom end of the fixed cylinder 51 and communicate with the evaporation core 56. The lower ends of the evaporation core connecting pipe 54 and the drain pipe 55 pass through the bottom of the cooling cylinder 1. The evaporation core 56 is fixedly installed inside the fixed cylinder 51. The fixed cylinder 51 is made of heat-insulating material.

[0035] In this invention, when air flows to the inlet 52 of the evaporation system, it enters the interior of the fixed cylinder 51 through the inlet 52. Subsequently, the evaporation core 56 operates to evaporate and cool the air. After evaporation and cooling are completed, the gas is discharged through the outlet 53 of the evaporation system. The drain pipe 55 can discharge the water generated during evaporation from the fixed cylinder 51.

[0036] Example 3: In some embodiments, such as Figure 4As shown, as a preferred embodiment of the utility model, the evaporation core 56 can adopt the plate cooler, and the plate cooler is composed of thin metal sheets pressed with corrugated shape. The narrow and tortuous channels are formed between two adjacent sheets, and the cold and hot fluids flow through the channels only once. The middle heat insulation sheet plays the role of separating the fluids, and ensures that the circulating cold air and hot air realize effective heat exchange through the heat insulation sheet.
