Combined type pressurization dehumidification system

Abstract

The invention discloses a combined type pressurization dehumidification system, and belongs to the field of air conditioning equipment. The system is composed of a first-stage air compressor, a primary radiator, a second-stage air compressor, a secondary radiator, a heat regenerator A, a condenser, a high-pressure water separator, a first-stage turbine, a second-stage turbine, a rotary dehumidifier, a heat regenerator B, a pressure limiting valve, a fan and a motor. After to-be-treated wet air is subjected to pressure rising and cooling twice, most water vapor in the wet air is condensed into free water. And the water is separated from the wet air through the high-pressure water separator, the treated wet air is subjected to physical adsorption dehumidification through the rotary dehumidifier again to become dry air, and finally the initial temperature and pressure are recovered after being subjected to heat regeneration and pressure relief so that the dry air can be further used. According to the system, a pressurization dehumidification mode is adopted, compared with a traditional cooling dehumidification method, the dehumidification efficiency is higher, and high-dew-point temperature dehumidification can be realized. Meanwhile, in consideration of economical performance, deep dehumidification continues to be conducted through the rotary dehumidifier, and finally the state of the low dew point temperature is achieved. The system can be applied to air dehumidification in large spaces such as a factory buildings in a high-temperature and high-humidity environment.

Description

technical field [0001] The invention belongs to the field of air conditioning equipment and relates to a combined pressurization and dehumidification system. Background technique [0002] In industrial production, the humidity of the working environment is an important parameter. Excessive humidity may cause electronic equipment to malfunction and be damaged, and the staff in it may also feel unwell. At the same time, some special work products are sensitive to moisture in the air and need to be stored in a dry environment. In such industrial scenarios, it is necessary to dehumidify the ambient air. At present, the dehumidification method used in most engineering applications is the cooling dehumidification method, that is, the dehumidification is carried out by reducing the temperature of the humid air below its dew point temperature to precipitate moisture, but this method does not have a good dehumidification effect when the air dew point temperature is low, and System ...
