A total heat recovery fresh air purification system based on nanofluid

Abstract

The invention discloses a total heat recovery fresh air purification system based on nanofluid, which includes a fresh air treatment module and a return air treatment module, wherein the fresh air treatment module includes a composite photocatalytic module, a bubbling photocatalytic module, a filler sterilization module and a water washing module. The defogging module and the return air processing module include a return air bubbling module and a return air spray heat exchange module. The outdoor air enters the room after being processed by the fresh air processing module, and the indoor return air is passed to the outside after being processed by the return air processing module. The system of the present invention converts the traditional "gas-gas" heat exchange between fresh air and return air into "gas-nanofluid-gas" heat exchange, and utilizes TiO synergistically 2 The photocatalytic degradation of organic pollutants of nanoparticles and the strong bactericidal effect of Ag nanoparticles, through the switching of indoor purification mode and fresh air purification mode, a purification system suitable for both indoor air pollution and outdoor air pollution is obtained.

Description

technical field [0001] The invention relates to a total heat recovery type fresh air purification system based on nanofluid, belonging to the technical field of air purification. Background technique [0002] Good air quality is conducive to improving the comfort of the environment and ensuring the physical and mental health of the public, so high-quality fresh air supply is particularly important. At present, air purification devices at home and abroad are mainly based on solid adsorption of activated carbon, which do not have the functions of degrading and sterilizing volatile organic pollutants. For severe air pollution, the consumption of consumables is large, and bacteria are easy to breed, causing secondary pollution. [0003] On the other hand, the research on nanofluids has been carried out for more than 20 years, but the application of nanofluids is still in the experimental and theoretical stage. The biggest challenge is that nanofluids cannot maintain their disper...

Problems solved by technology

At present, air purification devices at home and abroad are mainly based on solid adsorption of activated carbon, which do not have the functions of degrading and sterilizing volatile organic pollutants. For severe air pollution, the consumption of consumables is large, and bacteria are easy to breed, causing secondary pollution.

[0003] On the other hand, the research on nanofluids has been carried out for more than 20 years, but the application of nanofluids is still in the experimental and theoretical stage. The biggest challenge is that nanofluids cannot maintain their dispersion stability for a long time, that is, there is a certain shelf life.
