Abstract

The invention discloses an air dehumidification device based on electrodialysis. The air dehumidification device comprises a direct current power supply and a dehumidification unit, wherein the dehumidification unit comprises a positive electrode, a negative electrode, a macromolecule separation film, a plastic film, a dehumidification chamber and a sweeping chamber. Wet air can be directly dehumidified according to directional movement of water steam in a direct current electric field and a high osmotic coefficient of the macromolecule separation film to steam molecules, so that a dehumidification effect and the dehumidification accuracy are improved, and the unnecessary energy consumption is avoided. Compared with a conventional freezing dehumidification device, the air dehumidification device is simple in structure and convenient to operate. The device can be driven by a clean and environmentally-friendly solar photovoltaic power generation system (or systems for generating power such as a wind energy power generation system), so that effects of saving energy and reducing emission are achieved, and various natural energies are effectively used.

Description

technical field [0001] The invention belongs to the technical field of air dehumidification and heat and humidity independent treatment, and relates to a novel air direct dehumidification device based on electrodialysis. Background technique [0002] Efficient air dehumidification is the key and bottleneck to realize the independent treatment of heat and humidity. It is also widely used in air conditioning and other industrial fields, and is of great significance to building and industrial energy conservation. The current air dehumidification technology mainly includes refrigeration dehumidification, liquid hygroscopic agent dehumidification, solid adsorbent dehumidification, membrane dehumidification and pressure dehumidification. The traditional air treatment method is refrigerated dehumidification. Due to the limited temperature of chilled water, the dehumidification capacity of refrigerated dehumidification is limited, and the energy consumption of chillers will also inc...
