Inside cooling film dehumidifier and air dehumidification purification device using same

Abstract

The invention relates to the field of air sterilization purification and humidity control, in particular to an inside cooling film dehumidifier and an air dehumidification purification device using the same. The inside cooling film dehumidifier comprises a solution flow passage and an air flow passage in mutually parallel and alternate arrangement, wherein a cooling pipe is arranged inside the solution flow passage; cooling liquid or cooling gas is introduced into the cooling pipe, and is used for cooling the solution in the solution flow passage; the cooling pipe brings away the heat of the dehumidification solution; the temperature of the solution is lowered; the moisture absorption performance of the solution is improved; the cooling pipe is arranged inside the solution flow passage, so that the additional addition of the flow passage is not needed; the structure is compact; the solution flow passage dead regions are eliminated by controlling the pipe diameter size and the pipe space distribution; the heat transfer and mass transfer efficiency is improved, so that the performance of the film dehumidifier is improved.

Description

technical field [0001] The invention relates to the fields of air sterilization purification and humidity control, in particular to an internal cooling membrane dehumidifier and an air dehumidification purification device using the dehumidifier. Background technique [0002] Air humidity is an important factor affecting air quality, and it is of great significance to daily life and industrial production. Studies have shown that the relative humidity suitable for the human body is 40-60%. Excessive humidity will cause discomfort to the human body, and in severe cases, it will also cause a large number of certain viruses and bacteria to multiply inside the building. For hospital wards, there are not only strict air humidity requirements, but also strict air cleanliness requirements. It is necessary to efficiently remove suspended particles, harmful gases and bacteria in the air in hospital wards. [0003] In recent years, with the development of membrane materials, liquid deh...

In this dehumidifier, a selectively permeable membrane is used to separate the air from the desiccant fluid. The membrane prevents droplets of the desiccant fluid from entering the process air, thus preventing the corrosive dehumidification encountered in conventional packed liquid dehumidifiers. Serious harm caused by the entrainment of liquid droplets, thereby improving the quality of the air and ensuring that the air is not polluted by the dehumidification liquid. However, most of the conventional membrane dehumidifiers are difficult to cool the dehumidification solution. The temperature of the dehumidification solution increases with the absorption of water. increase, the dehumidification efficiency decreases

[0004] At present, many devices combining air dehumidification and air purification functions have been proposed in the industry, and many similar products have appeared on the market. The device realizes the dehumidification and purification functions of the air, but in this invention, if the air is directly in contact with the dehumidification liquid for dehumidification and purification, the air may be affected by the dehumidification liquid and the purification effect is not good, and the dehumidification liquid may need to be replaced regularly
