As shown in fig. 1 and 2, a liquid inlet pipe 43 and a liquid outlet pipe 44 are arranged between the water-cooled condenser 41 and the cooling tower 42 in the cooling assembly 4, so that the cooling liquid can circulate between the water-cooled condenser 41 and the cooling tower 42; the water-cooled condenser 41 is used for relatively low condensing temperature, which is beneficial to the refrigerating capacity and the running economy of the compressor unit 31; in this embodiment, the water-cooled condenser 41 is a vertical shell-and-tube condenser, the cooling water flows directly and has a high flow rate, a common water source can be used as the cooling water, and the cooling water can be recycled for many times, so that the cost is saved; the cooling tower 42 is generally installed outside the dehumidifier body 1 because it has a large volume and requires a certain height.

As shown in fig. 3, when the refrigerant is transmitted to the water-cooled condenser 41 through the compressor unit 31 in the process of each circulation flow of the refrigerant in the water-cooled condenser 41, the evaporator, the compressor unit 31 and the regenerative condenser, the refrigerant is a high-temperature and high-pressure gaseous medium, and the coolant circulating between the cooling tower 42 and the water-cooled condenser 41 is a liquid medium, so that the refrigerant releases heat and absorbs heat during the heat exchange process of gas-liquid contact in the water-cooled condenser 41, the temperature of the refrigerant is reduced, the cooling effect of the refrigerant is recovered, and the air can be continuously absorbed during the whole circulation flow of the refrigerant.

In the actual dehumidification process, in the gas-liquid contact heat exchange process of the cooling liquid and the refrigerant, the heat in the gaseous refrigerant is not enough to exchange heat with all the cooling liquid, the utilization of the cooling liquid is not complete, the utilization rate of the cooling liquid is low, and the energy is wasted; therefore, as shown in fig. 1 and fig. 2, an adjusting device 45 of VB7300 series is disposed on the liquid inlet pipe 43, the adjusting device 45 is a three-way structure, two ports of the adjusting device 45 are connected to the liquid inlet pipe 43 for transferring the cooling liquid from the cooling tower 42 to the water-cooled condenser 41, and the other port is connected to the liquid outlet pipe 44, and the adjusting device 45 is also connected to the water-cooled condenser 41, because the heat exchange between the cooling liquid and the cooling medium is performed in the water-cooled condenser 41, the proportion of the split flow of the cooling liquid is adjusted by measuring the pressure of the gaseous cooling medium in the water-cooled condenser 41 and controlling the adjusting device 45 according to the magnitude of the pressure, thereby ensuring that the utilization rate of the cooling liquid is highest in the heat exchange process between the cooling medium and the cooling liquid. Therefore, in the actual using process, the adjusting device 45 is arranged to split the cooling liquid according to the pressure of the gaseous refrigerant in the water-cooled condenser 41, wherein one part of the split cooling liquid enters the water-cooled condenser 41 to exchange heat with the refrigerant, and the other part of the split cooling liquid returns to the cooling tower 42 from the liquid outlet pipe 44 to wait for the next circulation, so that the maximum utilization of the cooling liquid is realized, the waste of the cooling liquid is reduced, and the energy conservation and the high efficiency are realized.

In the actual dehumidification process, the rotary wheel dehumidification technology is often adopted for the requirement of ultralow humidity below 7 ℃, and the general dehumidification rotary wheel 22 can meet the requirement, but when the requirement of ultralow humidity with low dew point below 60 ℃ is met, a cold blowing area is added on the rotary wheel to assist a regeneration area to cool a high-temperature rotary wheel just rotating out of the regeneration area and treat the cross wind and leakage of the regeneration area, so that the possibility of low dew point is created; therefore, at least 1 rotating wheel assembly 2 can be arranged in the rotary dehumidifier, as shown in fig. 3, in the utility model, because the dehumidifier needs to reach low dew point, the rotating wheel assemblies 2 are arranged into 2 groups, including the first rotating wheel assembly arranged in the upper box 11 and the second rotating wheel assembly arranged in the lower box 12, two rotating wheel assemblies 2 are arranged in an upper-lower stacking manner, as shown in fig. 6 and 7, the rotating wheel assemblies comprise a rotating wheel frame 21 and a dehumidifying rotating wheel 22 arranged on the rotating wheel frame 21, the rotating wheel frame 21 is of a rectangular frame structure, the upper side and the lower side of the rotating wheel assembly are arranged in an unclosed manner, the dehumidifying rotating wheel 22 is convenient to install, an air inlet 211 and an air outlet 212 which are arranged in a circular manner are arranged on the rotating wheel frame 21, and the air inlet 211 and the air outlet 212 are respectively provided with a regeneration channel air outlet 213; meanwhile, the air inlet 211 and the air outlet 212 are provided with the supporting rods 215, the center of the supporting rod 215 is provided with the rotating member 2151 coinciding with the rotation center of the desiccant rotor 22, when the desiccant rotor 22 is installed in the rotor frame 21, the two rotating members 2151 are pressed inward to fit the rotation center of the desiccant rotor 22, and the desiccant rotor 22 is installed on the rotor frame 21.

As shown in fig. 6, since the moisture absorbent carrier layers of any adjacent partitions on the dehumidifying rotor 22 are arranged perpendicular to each other in the present invention, the structural strength of the dehumidifying rotor 22 is high at the rotation center, when the rotating member 2151 tightly contacts the moisture absorbent carrier layers to press and fix the dehumidifying rotor 22 inwards, the situation that the dehumidifying rotor 22 is damaged due to too large pressing force during use is avoided; in addition, in the first rotating wheel assembly, the dehumidifying rotating wheel 22 is a high-efficiency regeneration dehumidifying rotating wheel and comprises a regeneration part and a moisture absorption part, and in the second rotating wheel assembly, the dehumidifying rotating wheel 22 is a low-temperature high-efficiency regeneration dehumidifying rotating wheel and comprises a regeneration part, a moisture absorption part and a cold blowing part; a cold blowing part is arranged on the dehumidifying rotating wheel 22 in the second rotating wheel component and is used for cooling the dehumidifying rotating wheel 22 which just rotates out of the regeneration area, so that the aim of low dew point is fulfilled, and the whole dehumidifying process is more energy-saving and efficient; in addition, the rotating wheel assembly 2 further comprises a driving device, the driving device is a motor, and the driving device is connected with the dehumidifying rotating wheel 22 through a transmission belt, so that the dehumidifying rotating wheel 22 is driven to move; for set up the pivot for the rotation center at dehumidification runner 22 and pass through drive arrangement drive pivot and rotate dehumidification runner 22, adopt the drive belt cover to establish and drive dehumidification runner 22 pivoted mode on the outer wall of dehumidification runner 22, reduced the inside extrusion force that receives of dehumidification runner 22, prevent that dehumidification runner 22 is impaired.
