Pressurizing solution deep dehumidifying device and pressurizing solution deep dehumidifying method

Abstract

The invention discloses a pressurizing solution deep dehumidifying device and a pressurizing solution deep dehumidifying method. In the pressurizing solution deep dehumidifying device, air and a strong solution are pressurized to a certain high-pressure state and then conveyed into a dehumidifier so as to be dehumidified, the dehumidified air and a weak solution are throttled to a normal-pressure state by a throttle valve, thus providing dry air with very low humidity, so as to dry spaces or objects which need to be dried. A throttled weak solution flowing out from the dehumidifier is conveyed into a normal-pressure regenerator through a solution pump for regeneration, and then is recycled while achieving a certain concentration. Because the pressurized air has higher water vapor partial pressure than the air under normal pressure, thus increasing the difference of the water vapor partial pressure between the air and a solution surface, and further enhancing the dehumidifying process; after contacting with a dehumidifying solution, the air can also reach the water vapor partial pressure approximate to the solution surface, after dehumidified high-pressure air is throttled to normal-pressure air, the lower water vapor partial pressure is got, and therefore deep dehumidified and dried air with lower moisture content can be obtained.

Description

technical field [0001] The invention relates to a pressurized solution deep dehumidification device and a dehumidification method, belonging to the technical field of drying and solution dehumidification. Background technique [0002] With the rapid development of modern industry, the requirements for the environmental humidity of the workshop are getting higher and higher. Improper humidity in the workshop will affect the health of workers, product quality problems, damage to mechanical equipment, smooth work, etc. In some industrial dehumidification processes, humid air with very low dryness is sometimes required. In order to obtain humid air with low dryness under normal operating concentration and temperature conditions, the deep dehumidification of pressurized solution can meet this low dryness in industry. Air needs. [0003] At present, the commonly used air dehumidification methods include cooling dehumidification, solid adsorbent dehumidification, and wheel dehumid...

AI Technical Summary

Problems solved by technology

Although these traditional dehumidification methods are widely used, there are still some shortcomings.

For example, the freezing dehumidification method cannot achieve a very low dew point, and consumes a lot of energy; the regeneration process of the solid desiccant is complicated and consumes a lot of energy, etc.
