Multistage air deep dehumidification device for ultra-low dew point environments

Abstract

The invention discloses a multistage air deep dehumidification device for ultra-low dew point environments. The multistage air deep dehumidification device comprises a first fan, a primary efficiencyfilter, a medium efficiency filter and a first surface air cooler which are sequentially arranged in the outdoor fresh air direction and further comprises a solution dehumidification system, a first fresh air branch circuit, a second fresh air branch circuit, a third fresh air branch circuit, a first air returning branch circuit and a second air returning branch circuit which are arranged behind the first surface air cooler. A cold and heat source of a solution dehumidification cycle is provided by an independent vapor-compression-type refrigeration cycle, a regenerative heat source of two-stage rotary-wheel dehumidification uses condensation heat of another vapor-compression-type refrigeration cycle, and meanwhile shortage of the condensation heat is compensated in an electric heating mode. The evaporative cooling capacity of the vapor-compression-type refrigeration cycles is provided for an air-evaporator to cool air. After treating through the device, the humidity content of the fedair can be lowered to 0.01 g / kg.

Description

technical field [0001] The invention relates to a deep air dehumidification and refrigeration device capable of providing an ultra-low humidity environment for industrial buildings, which comprehensively applies technologies such as condensation dehumidification, solution dehumidification and runner dehumidification, and belongs to the technical field of air conditioning system design and manufacture. Background technique [0002] With the rapid development of modern industry, the types of products produced by industry are constantly increasing, and the division of labor in the factory workshop is becoming more and more clear. Therefore, the temperature and humidity requirements for the production environment are also getting higher and higher. Accurate temperature and humidity control determines product quality to a large extent, and has a great impact on the stable operation of production machinery and equipment and the health of workers. In some special industrial occasio...

Problems solved by technology

However, the dehumidification process of the rotary wheel is often accompanied by the release of heat. When the air is dehumidified, there will be a large temperature rise, and the excessively high supply air temperature cannot meet the requirements of the ambient temperature in the building.

And when the humid air in the high-humidity range is processed, the economical efficiency of the dehumidification rotor is greatly reduced due to the high energy consumption of the regeneration of the dehumidification rotor.

The defects of inflexible adjustment of air parameters and poor economy are the most important factors restricting the operation of the rotary dehumidification equipment alone
