Corrosion proof heat and mass transfer device without carrying liquid and with solution for adjusting humidity

Abstract

The invention discloses a heat and mass exchange device with corrosion-prevention and no liquid entrapment for humidity regulation by a solution, belonging to the field of air conditioning, energy and heat exchange equipment. A plurality of fins are concentrically adhered or threadedly connected along the axial line of basic holes or integrally injection-molded to form finned tubes, which are then spiced into the finned tube type heat and mass exchange device. The fins and basic tubes of the device are made from high-heat conducting plastic material, so as to solve solution corrosion and effectively transfer heat. Wetting material is adhered on the surface of fins, the solution is adsorbed inside the wetting material, so as not to be blown off and solve liquid entrapment of air. The fins surface is the place for heat and mass exchange of the solution and air, and fluid is filled inside the fin basic tubes to provide cold for cooling the solution during dehumidification or heat for heating the solution during regeneration, so as to realize high-efficient air dehumidification or solution regeneration. The entire device adopts a modularized structure, and the length can be adjusted in three directions to fulfill the requirements of air ducts of different sizes.

Description

technical field [0001] The invention belongs to the field of air conditioners, energy sources and heat exchange equipment. In particular, it relates to an anti-corrosion and non-liquid entrainment heat and mass exchange device for adjusting the humidity of the solution, which can realize the solution dehumidification function of internal cooling and the solution regeneration function of internal heating. Background technique [0002] Solution dehumidification is to use the property that the surface vapor pressure of some salt solutions is lower than the water vapor partial pressure of the treated air, absorb the moisture in the air, and dehumidify the air. Solution regeneration refers to heating the solution, etc., to evaporate the water in the solution and increase the concentration. Solution dehumidification consumes low-grade waste heat and waste heat, which can greatly reduce the energy consumption of air conditioners. [0003] When the solution dehumidifies the air, t...

Problems solved by technology

At present, there are devices with similar functions made of metal, which will be corroded by chemical reaction with salt solution

In addition, these devices with similar functions have no surface treatment. Since the solution flows in the form of droplets on ordinary surfaces, it cannot be fully spread on the surface. The heat and mass exchange area is small, and the solution flows along the surface as droplets or liquid films. , are easily blown off the surface and into the treated air, which creates the problem of air entrainment of the solution
