Embodiment 1

[0031] Embodiment 1: The present invention provides a falling film liquid humidity conditioner based on the polarization effect of a high-voltage electrostatic field. The liquid humidity conditioner has an electric field strengthening device 300, such as Figure 4As shown, the electric field strengthening device 300 includes a first electrode 301 and a second electrode 302 that are respectively connected to both ends of the power supply to form a non-uniform electric field, and an electric field that can place a falling film device is formed between the first electrode 301 and the second electrode 302 , the first electrode 301 forming a non-uniform electric field can be a thin metal plate, and the second electrode 302 can be a metal wire. The specific application form can be that the metal thin plate is cylindrical, and the metal wire is placed in the cavity surrounded by the cylindrical metal thin plate The central axis forms a non-uniform electric field between the metal thin...

Embodiment 2

[0032] Embodiment 2: An optional structure of the liquid humidity conditioner is as follows Figures 1 to 4 As shown, the liquid humidifier adopts a cylindrical design, including a casing 100, a falling film device 200 and an electric field strengthening device 300. The liquid humidifier is a closed structure, except for the inlet and outlet of the solution to be treated and the inlet and outlet of air. , and some wire interfaces are not connected with the outside area.

[0033] The casing 100 of the liquid humidity conditioner adopts insulating material, and is provided with a first inlet 101 for air entry, a first outlet 102 for air delivery, a second inlet 103 for solution entry, and a second outlet for solution delivery. The outlet 104, the second inlet 103 and the first outlet 102 are located at the upper end of the housing 100, the second outlet 104 and the first inlet 101 are located at the lower end of the housing 100, and the connecting section of the solution inlet a...

Embodiment 3

[0041] Embodiment 3: Since the structure of the regenerator and the dehumidifier are similar and the principle is the same, but the water molecules move in the opposite direction, so on the basis of the structure of Embodiment 2, it is necessary to change the direction of the strength of the non-uniform electric field, and the water molecules flow from the wire side (Molecules in the solution in the wetting layer) migrate toward the direction of the thin metal plate (migrate to the heat exchange medium in the flow channel) to accelerate the migration to realize solution regeneration.

[0042] The electric field strengthening device 300 used in the regenerator structure is as Figure 5 As shown, it is used to apply an electric field to the falling film device. The inner wall of the metal sheet of the electric field strengthening device 300 is provided with a metal burr 303, and an uneven electric field is formed by the increased metal burr. For example, in a specific application...

Abstract

The invention discloses a falling film liquid humidity conditioner and a method based on the polarization effect of a high-voltage electrostatic field. The liquid humidity conditioner of the present invention includes an electric field strengthening device for applying an electric field to a falling film device, and the electric field strengthening device includes a first electrode and a second electrode connected to both ends of the power supply to form a non-uniform electric field, the first electrode An electric field capable of placing the falling film device is formed between the first electrode and the second electrode. The invention utilizes the effect of the non-uniform high-voltage electrostatic field on the polar molecule water molecules, accelerates the migration process of the water molecules in the solution to the air, and distributes the solution evenly through the arrangement of the wetted materials. The device requires extremely small power supply and low energy consumption, thereby improving the efficiency of the system.

Description

technical field [0001] The invention relates to a humidity regulating device, in particular to a falling film liquid humidity regulator and method based on the polarization effect of a high-voltage electrostatic field. Background technique [0002] Since the idea of ​​the liquid dehumidification air conditioning system was put forward in the 1950s, with the development of industrial technology and technological level, the solution dehumidification system has been widely studied and applied, among which the salt solution dehumidification system is particularly significant. , Textile, frost suppression in cold storage, compressed air drying, etc. A solution dehumidification system consists of a dehumidifier and a regenerator. In the dehumidifier, the dehumidification solution with low water vapor partial pressure is in contact with the air to be dehumidified, and the water vapor partial pressure difference drives the moisture in the air to transfer to the solution to reduce t...
