TECHNICAL FIELD
[0001] The utility model relates to air treatment technical field, concretely relates to a novel solution dehumidifier unit and solution heat exchange device thereof. BACKGROUND
[0002] Solution dehumidifier adopts hygroscopic solution to process air, and realizes the humidity processing of air by using the heat and moisture transfer between solution and air.According to whether there is cold input in the dehumidification process, it can be divided into adiabatic type and internal cooling type dehumidifier.In the adiabatic type dehumidifier, the latent heat of vaporization is released in the dehumidification process, which will cause the temperature of solution to rise, resulting in the decline of the dehumidification capacity of solution.In the internal cooling type dehumidifier, the cooling medium (such as cooling water, cold air, etc.) is introduced into the dehumidification process, and the heat released in the dehumidification process is taken away, so as to maintain the dehumidification capacity of solution.Compared with the adiabatic type dehumidifier, the internal cooling type dehumidifier has better dehumidification effect.In the internal cooling type solution dehumidifier, the solution and air are in direct contact, and the heat and mass transfer process is carried out;the cooling medium is in indirect contact with the solution, so as to reduce the temperature of solution, thereby maintaining the strong dehumidification capacity of solution.The internal cooling type solution dehumidifier / regeneration device involves three fluids, which are air, hygroscopic solution and cooling / heating medium.Taking the dehumidification condition as an example, the air and solution are in direct contact, the water vapor in the air enters the solution, which shows that the air is dehumidified, and the concentration of solution is reduced due to the absorption of water in the air, and most of the latent heat of vaporization released in the dehumidification process is absorbed by the solution;the cooling water and solution are in indirect contact for heat exchange, and the cooling water takes away the latent heat of vaporization absorbed by the solution, so as to inhibit the temperature rise of solution in the dehumidification process, so as to maintain the dehumidification capacity of solution.The heat and mass transfer principle of the regeneration condition is the same as that of the dehumidification condition, and only the heat and mass transfer direction is different.
[0003] The conventional lithium chloride / lithium bromide dehumidification solution is corrosive to metal, so the conventional copper tube aluminum fin internal cooling tube fin heat exchanger cannot be used.With the use of new dehumidification solution without corrosion, it is possible to use metal internal cooling tube fin heat exchanger, and if a non-metal tube fin heat exchanger made of plastic or other materials is used, the heat exchange performance will be greatly reduced.
