Description

Technical Field

[0001] The utility model relates to the technical field of rotary dehumidification, in particular to a rotary dehumidification system adopting a heat pump and a three-dimensional heat pipe. Background Art

[0002] Rotary dehumidifier is an important branch of air conditioning field and a typical representative of temperature control dehumidification. It dehumidifies the environment through the adsorption (rotary) principle of physical reaction. It is mainly used in aerospace, pharmaceutical, lithium battery, food, paper printing, rubber industry and other fields.

[0003] The existing rotary dehumidifier is divided into a dehumidification air duct and a dehumidification air duct. The dehumidification section of the dehumidification wheel in the body is divided into a processing area and a regeneration area by a sealing system. In the processing area, the water vapor in the processed fresh air is adsorbed by the hygroscopic medium in the wheel and becomes dry, hot air. The wheel gradually tends to saturation due to moisture absorption. In the regeneration area, the regenerated fresh air is heated to 90-140°C by electric heating, steam heating, etc., and after passing through the saturated wheel after moisture absorption to evaporate the water to restore its dehumidification capacity, it becomes 45-75°C high-temperature and high-humidity air and is discharged to the outside by the regeneration fan. The regeneration temperature required for the dehumidification wheel is relatively high, and the waste humid hot air is directly discharged, which has problems such as low heating efficiency, high regeneration energy consumption, and low energy utilization.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1 , a rotary dehumidification system using a heat pump and a three-dimensional heat pipe, comprising a dehumidification rotary device 14, a fresh air duct 1 disposed on one side of the dehumidification rotary device, a first evaporator 3 connected to the fresh air duct and the other end of which is connected to the dehumidification rotary device, a second evaporator 7 connected to the other side of the dehumidification rotary device and connected to the channel of the first evaporator, and a fresh air fan 15 connected to the second evaporator;

[0021] The dehumidification wheel device is connected to a regeneration fresh air system, which includes a regeneration air duct 2, a U-shaped three-dimensional heat pipe condensation section 11 disposed at the rear end of the regeneration air duct, a first condenser 5 disposed at the rear end of the U-shaped three-dimensional heat pipe condensation section, a second condenser 9 disposed at the rear end of the first condenser, and an electric auxiliary heating device 17 disposed at the second condenser and connected to the dehumidification wheel device; and also includes a U-shaped three-dimensional heat pipe evaporation section 12 disposed at the other end of the dehumidification wheel device and connected to a channel at one end of the electric auxiliary heating device, and a regeneration fan 16 disposed at the rear end of the U-shaped three-dimensional heat pipe evaporation section;

[0022] The U-shaped three-dimensional heat pipe evaporation section 12 and the U-shaped three-dimensional heat pipe condensation section 11 are connected to each other through the U-shaped three-dimensional heat pipe connection section 13; the U-shaped three-dimensional heat pipe uses the working fluid in the pipe, and uses the principle of evaporation heat absorption and condensation heat release to guide the heat from the higher temperature end to the lower temperature end, and the whole process has no energy consumption at all. It not only recovers the heat in the regeneration exhaust air of the rotor and reduces the energy consumption of regeneration heating, but also reduces the environmental pollution caused by the emission of high-temperature and high-humidity gases. The U-shaped three-dimensional heat pipe not only has thermal superconductivity, but also has the advantages of compact size, light weight, no noise, and no need for auxiliary transmission parts. The U-shaped three-dimensional heat pipe recovers the heat in the exhaust air to heat the outdoor regeneration fresh air, which can ensure that the temperature fluctuation of the preheated regeneration fresh air is very small, which is conducive to improving the stability of the operation of the heat pump system. The U-shaped three-dimensional heat pipe recovers the heat in the exhaust air to heat the outdoor regeneration fresh air, which reduces the operating energy consumption of the first heat pump system and improves the COP value of the heat pump system.

[0023] The second condenser 9 and the second evaporator 7 are connected to each other and form a circuit, a second throttle valve 10 is provided on one group of circuits between the two, and a second compressor 8 is provided on the other group of circuits;

[0024] The first condenser 5 and the first evaporator 3 are connected to each other to form a loop, and a first throttle valve 6 is provided on one of the loops between the two, and a first compressor 4 is provided on the other loop;

[0025] In this implementation case, in the fresh air duct 1, the fresh air treated by the rotor first passes through the first evaporator for preliminary cooling (or cooling and dehumidification), and then passes through the dehumidification rotor for adsorption dehumidification to further reduce the moisture content of the air. Since the rotor will transfer heat to the treated air to increase its temperature during this process, a second evaporator is provided after the dehumidification rotor to adjust the air temperature to a suitable air supply temperature, and then the air is supplied through the air supply fan. In the regeneration duct, the fresh air regenerated by the rotor is first preheated by the U-shaped three-dimensional heat pipe condensation section, and then respectively passes through the first condenser, the second condenser and the electric auxiliary heating device (turned on when the condensation heat is insufficient) to heat to the required regeneration temperature, and then passes through the dehumidification rotor to evaporate the moisture therein and turn it into high-temperature and high-humidity exhaust gas. This part of high-temperature and high-humidity exhaust gas is cooled down by the evaporation section of the U-shaped three-dimensional heat pipe, and finally discharged to the outside through the regeneration fan. When the regeneration exhaust air passes through the evaporation section of the U-shaped three-dimensional heat pipe, the liquid in the three-dimensional heat pipe absorbs heat and evaporates and gasifies, cooling the regeneration exhaust air; the heat after evaporation and absorption is transferred to the condensation section of the U-shaped three-dimensional heat pipe through the connection section of the U-shaped three-dimensional heat pipe, and the condensation releases heat to preheat the regeneration fresh air, reducing the energy consumption required for heating the regeneration fresh air. This system places an evaporator in the fresh air duct, and uses the evaporator to cool and dehumidify the treated fresh air. At the same time, a condenser is placed in the regeneration duct, and the condenser condensation releases heat to heat the air passing through the regeneration duct to reach the required regeneration temperature. The electric auxiliary heating device is placed at the rear end of the condenser. When the condenser provides insufficient heat, the electric auxiliary heating device is turned on to supplement the required heat; in order to make full use of this part of the heat in the waste humid hot air discharged by the rotor regeneration, a U-shaped three-dimensional heat pipe is added to the system, and the U-shaped three-dimensional heat pipe condensation section is placed at the regeneration fresh air inlet, and the evaporation section is placed at the regeneration exhaust outlet. The thermal superconductivity of the U-shaped three-dimensional heat pipe is utilized to recover the heat in the regenerated exhaust air, thereby reducing the regeneration energy consumption required by the rotor.

[0026] The benefit of the utility model is that the technical solution adopts the high energy efficiency of the heat pump to transfer the heat in the cooling and dehumidification process of the treatment area to the regeneration area to heat the regenerated fresh air through multiple heat pump systems, thereby reducing the regeneration energy consumption of the wheel, making the dehumidification wheel more capable of dehumidification and more energy-saving and efficient.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
