Experimental Study on the Regeneration Process of the Dehumidification System of Lithium Bromide Solution Based on Computer

Abstract

Dehumidification is a common problem in production and life. solution dehumidification method is to use salt solution with strong hygroscopicity as dehumidifier, the salt solution is in direct communicate with the treated air because of the pressure variance between the water vapor force on the side of the salt solution and the water vapor force of the treated air, the moisture is driven to transfer between the air and the hygroscopic solution, thus the change of air humidity is realized. In short, the high concentration of lithium bromide and other aqueous solutions absorb the water vapor in the atmosphere by the force difference between the water vapor and the treated air, thus completing the dehumidification process of the air. After the solution absorbs water in the air, it needs to be concentrated and regenerated to restore moisture absorption capacity. Many scholars at home and abroad have studied the solution dehumidification system. Florida Solar Energy Center Swami proposed a system for regeneration of solutions using roofs as solar absorbing surfaces in 1998. Nelson dehumidification performance of Li Cl solution as dehumidifier was studied. Due to the fact that the surface vapor pressure, specific heat capacity, corrosion and other physical and chemical properties of lithium bromide are better than those of lithium chloride and calcium chloride under the same PH and equal concentration, I have studied the regeneration process of dehumidification system of lithium bromide solution based on computer.
