Description

Technical Field

[0001] The utility model relates to the technical field of rotary dehumidifiers, and in particular to an energy-saving dual-rotor dehumidifier system for a chemical formation workshop. Background Art

[0002] The increasing use of battery-powered devices has led to rapid growth in the lithium battery industry in recent years. Formation is the final and crucial step in the lithium battery manufacturing process. Formation, also known as activation, refers to the initial charge and discharge process after initial assembly of a lithium battery to activate the battery and form a stable solid electrolyte interface (SEI) layer. This process has a crucial impact on the performance, reliability, and lifespan of lithium batteries. In lithium battery formation workshops, dual-rotor dehumidifiers are typically used to maintain the demanding humidity environment required for production. Formation typically takes approximately 24 hours, resulting in significant operating energy costs.

[0003] Existing technology, 2022113738719, in the chemical formation workshop, when the double-rotor dehumidifier unit processes the air, it first uses the front surface cooler to perform preliminary cooling and dehumidification, and the cooled air passes through the front rotor for adsorption dehumidification. After that, the treated fresh air is mixed with the primary return air, and the mixed air is cooled again by the middle surface cooler. The cooled mixed air passes through the rear rotor for adsorption dehumidification, further reducing the moisture content of the mixed air. Finally, the mixed air after adsorption dehumidification by the rear rotor is heated by the rear heater, and is sent to the chemical formation workshop after the temperature is raised to 45-55°C. In this process, the energy consumption of the surface cooler and the energy consumption of the rear heater account for a considerable part of the energy consumption of the unit. The energy consumption is extremely high, and there is a waste problem of the cooling and heating energy consumption offsetting each other.

[0004] Therefore, it is necessary to design an energy-saving dual-rotor dehumidifier system for the chemical workshop to solve the above problems. Utility Model Content

[0022] The fresh air processing system includes a fresh air inlet, a primary filter 2 connected to the fresh air inlet, a processing fan 2, a three-dimensional heat pipe pre-cooling section 4, a front surface cooler 5, a three-dimensional heat pipe reheating section 7, and a front rotor 8 connected in sequence;

[0023] The mixed air processing system includes a return air inlet, a medium efficiency filter 9 connected to the return air inlet, a second processing fan 10, a mid-level cooler 12, a rear rotor 13 and a high efficiency filter 16;

[0024] The rear impeller 13 and the front impeller 8 are connected to each other. The regeneration air of the rear impeller 13 enters the regeneration area of ​​the rear impeller through the heater and is transported to the front impeller 8 through the regeneration fan, passes through the filter and enters the heater of the front impeller 8, enters the regeneration area of ​​the front impeller, and is transmitted out through the fan of the front impeller 8.

[0025] The first heat pump system is composed of a first evaporator 6, a first condenser 14, a first compressor 18, and a first throttle valve 19 to form a circuit; the first compressor 18 is arranged at the upper circuit of the first evaporator 6 and the first condenser 14; the first throttle valve 19 is arranged at the lower circuit of the first evaporator 6 and the first condenser 14;

[0026] The first evaporator 6 is placed between the front surface cooler 5 and the three-dimensional heat pipe reheat section 7. The first evaporator is used for deep dehumidification to reduce the moisture content of the air entering the front rotor, reduce the dehumidification capacity borne by the front rotor, thereby lowering the regeneration heating temperature and reducing the regeneration heating energy consumption of the front rotor;

[0027] The first condenser 14 is disposed between the rear impeller 13 and the high efficiency filter 16 .

[0028] The second heat pump system is composed of a second evaporator 11, a second condenser 15, a second compressor 20, and a second throttle valve 21 to form a circuit; the second compressor 20 is arranged in the upper circuit of the second evaporator 11 and the second condenser 15; the second throttle valve 21 is arranged in the lower circuit of the second evaporator 11 and the second condenser 15;

[0029] The second evaporator 11 is arranged between the second processing fan 10 and the intermediate surface cooler 12; the second evaporator is used to pre-cool the air outlet temperature of the front rotor to reduce the cooling load of the intermediate surface cooler;

[0030] The second condenser 15 is disposed between the first condenser 14 and the high efficiency filter 16 .

[0031] When the temperature and humidity are low, in order to prevent the first condenser 14 and the second condenser 15 from providing insufficient heat, a heating device is provided between the second condenser 15 and the high efficiency filter 16 , and the required heat is supplemented by turning on the heating device 17 .

[0032] The working principle of this embodiment is as follows: In the fresh air duct 1, the rotor-treated fresh air passes through the primary filter 2 and is then delivered by the treatment fan 3 to the three-dimensional heat pipe pre-cooling section 4, the front surface cooler 5, and the first evaporator 6 for cooling and dehumidification. The air is then reheated by the three-dimensional heat pipe reheat section 7. The heated air passes through the front rotor 8 for adsorption and dehumidification. The treated fresh air is then mixed with the primary return air. The mixed air passes through the medium-efficiency filter 9 and is delivered by the treatment fan 10 to the second evaporator 11 and the intermediate surface cooler 12 for cooling. The cooled mixed air then passes through the rear rotor 13 for adsorption and dehumidification, further reducing the moisture content of the mixed air. Finally, the mixed air is heated by the first condenser 14 and the second condenser 15, and is sent to the chemical forming workshop after being filtered by the high-efficiency filter 16. The heat absorbed by the first evaporator and the second evaporator in front of the dehumidification wheel is used to heat the air treated by the rear wheel by the first condenser and the second condenser of the heat pump system, thereby reducing the heating energy consumption of the air supply of the rear wheel. By adding two sets of heat pump systems and heating devices, it is ensured that the main body of the system can increase the heat to a maximum of 45-50°, so as to be more adaptable to different workshop environments.

[0033] The benefits of the present invention are that the present technical solution utilizes U-shaped dehumidification three-dimensional heat pipes to pre-cool the fresh air, and transfers the coldness at the rear end of the first evaporator to the front end of the fresh air, saving the coldness of the front surface cooler. The entire process has no energy consumption at all. The installation of three-dimensional heat pipes and evaporators saves the coldness of the surface cooler and reduces the regeneration heating energy consumption of the dehumidification wheel. At the same time, under the action of two sets of heat pump systems, the condenser condenses and releases heat to heat the processed air passing through to reach the temperature required by the chemical workshop, thereby saving the energy consumption of the dehumidification wheel.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
