Working principle of rotary dehumidifier in lithium battery factory

1. Types of dehumidification methods
1. Cooling and dehumidification
Cool the air to below the dew point and remove the condensed moisture. Effective when the dew point is above
2. Compression dehumidification
Compress and cool the moist air to separate its moisture. It is effective in situations with small air volumes, but not suitable for situations with large air volumes.
3. Solid adsorption dehumidification
The water is adsorbed on the solid desiccant by capillary action. The dew point can be lowered, but the equipment will become larger when the adsorption area is large.
4. Liquid absorption dehumidification
The dew point can be reduced to about 10000A by spraying lithium chloride aqueous solution, but the equipment is large and the absorption liquid must be replaced.
5. Adsorption wheel dehumidification
The thin plate impregnated with desiccant is processed into a honeycomb wheel for ventilation. Its dehumidification structure is simple, and the dew point can reach below -70℃ after special assembly.
2. Suitable range of dehumidification
　　
3. Principles of air treatment
　　
Provide dry air continuously. The air treatment is a high-performance dry dehumidifier using a honeycomb dehumidification wheel.
The honeycomb rotor of the air treatment system continuously repeats the moisture absorption and regeneration action when rotating, without affecting the air flow, and continuously provides dry air with ultra-low dew point.
4. Honeycomb Rotor
　　
The dehumidifier's rotor uses a Japanese high-efficiency ceramic silicone rotor. This ensures that the dehumidifier's rotor is firm and dust-free even when passing through a large air volume. The Japanese high-efficiency ceramic silicone rotor is made of ceramic as the base material and mixed with silicone to form a honeycomb cylinder that is precisely cut. The entire rotor is a highly efficient moisture absorber that can handle 100% of wet air without falling off or deforming. The service life can reach more than 10 years, and it can be cleaned many times, with a very long service life.
5. Dehumidification principle of air treatment
The system uses a honeycomb-structured dehumidification wheel. As shown in the figure, the driving motor rotates the dehumidification wheel 8 to 18 times per hour, continuously repeating the moisture absorption and regeneration action to provide dry air.
The rotor is divided into a moisture absorption zone and a regeneration zone. After the moisture in the air is removed in the moisture absorption zone, the blower delivers the dried air into the room.
The wheel that has absorbed moisture moves to the regeneration area. At this time, the regeneration air (warm air) sent in from the reverse direction will drive away the moisture and allow the wheel to continue working.
The heating methods for regeneration air include steam, natural gas, coal gas, fuel gas, oil, electricity and other devices.
Due to the special properties of the high-efficiency ceramic silica wheel and zeolite wheel, the dehumidifier can continuously dehumidify at a large air volume and can meet extremely low moisture content requirements. After matching, the moisture content of the treated air can be lower than 0.0007g/kg
If you want to keep the temperature of the dry air stable, you can cool or heat the air at the dehumidifier outlet by installing an air conditioner or heater.
Air treatment characteristics
In the process of product production, the troubles caused by moisture to the product are always bothering humans. In the process of using solid adsorbents for moisture absorption, the adsorbents after moisture absorption are simultaneously regenerated and dehydrated, so that the solid adsorbents can be recycled and the entire moisture absorption work can be carried out continuously. It overcomes the shortcomings that static solid adsorption cannot dehumidify continuously and refrigeration condensation dehumidification is powerless under low temperature and low humidity conditions. It can give full play to its characteristics of continuous, stable and large dehumidification capacity under low temperature and low humidity conditions. Aobo's rotary dehumidifier is developed using this advanced technology and has special functions that others cannot. Compared with other dehumidification methods, rotary dehumidifiers have their own unique characteristics;
1) It is easy to obtain ultra-low humidity dry air.
2) It can continuously provide ultra-low humidity dry air with a dew point below 6°C, which cannot be achieved by cooling and dehumidification methods, at a low cost.
3) Simple operation and maintenance.
4) The structure is simple, the drive unit is simple, and dry air can be obtained by operating the dehumidification wheel, the regeneration heater and the blower, so the operation is very simple. In addition, it is a dry dehumidification type, no desiccant needs to be added, maintenance is convenient, and the operation and maintenance costs are low.
5) Excellent durability.
6) In a clean air environment, the performance of the dehumidification wheel will hardly decrease or degrade, and it can operate continuously for many years.
7) Complete range of machines.
8) From the standard type for general use to the low humidity type that can produce ultra-low humidity dry air, our company has a full range of machines suitable for various usage conditions.
9) Pollution-free green machine uses ceramic silica gel and zeolite wheels as non-toxic and odorless green desiccant, so the dehumidifier is safe, environmentally friendly, clean, free of floating dust and non-corrosive during use. Moreover, it can sterilize, which is particularly suitable for the pharmaceutical, food, biochemical and other industries.
