Regeneration system of dehumidifying solution for moist air

Abstract

The invention relates to a regeneration system of a dehumidifying solution for moist air, wherein a generator is internally provided with a heating coil and a condensing coil, and the condensing coil is in a condensing disc provided with a condensate outlet. A liquid outlet of a dilute solution storage tank is connected with a liquid inlet of the generator, and a liquid outlet of the generator is connected with an inlet of a solution heat exchange tube through a solution pump. An outlet of the solution heat exchange tube is divided into two paths, and one solution heat exchange tube is connected with a dehumidifying device through a flow adjusting valve while the other solution heat exchange tube is connected with a work liquid inlet of an ejector. A driven fluid inlet of the ejector is communicated with a gas outlet of the generator and an outlet of the ejector is connected with a liquid inlet of the dehumidifying device after being joined with an outlet of the flow adjusting valve. An outlet of the heating coil is connected with an inlet of a heater, an outlet of the heater is connected with a vapor-liquid separator through a bubble pump, a gas outlet of the vapor-liquid separator is connected with an inlet of the heating coil, and a liquid outlet of the vapor-liquid separator is connected with the inlet of the heater after being joined with the outlet of the heating coil.

Description

technical field [0001] The invention relates to a regeneration system of a dehumidification solution for dehumidification of humid air, belonging to the technical field of humid air dehumidification. Background technique [0002] At present, the most widely used solution dehumidifiers are LiBr, LiCl and CaCl. 2 and other solutions, while using CaCl 2 It is relatively rare for the solution to dehumidify alone. Regeneration is a central issue in this technology for dehumidification using highly hygroscopic solutions. The dehumidification and solution regeneration efficiency of solution dehumidifiers have always been the focus of research. Using waste heat as a heat source for solution regeneration has energy-saving significance. For example, the condensation heat of air-conditioning units used is used as a heat source for solution regeneration. Control the air-conditioning system, the system recovers the heat dissipation of the condenser of the air source heat pump unit, an...

[0003] However, no matter what method is used to improve the dehumidification and regeneration efficiency of the dehumidifier, the solution regeneration temperature is always the key factor affecting the solution regeneration. The regeneration temperature of the solution dehumidifier is generally 70-80°C. , the regeneration efficiency exceeds 55%; however, when the temperature of the heat source is lower than 50°C, the regeneration of the solution is very difficult or even impossible, but the higher the temperature, the more energy is required, which makes the solution regeneration system relatively more demanding on the heat source high
