Total heat recovery type fresh air purification system based on nano fluid

Abstract

The invention discloses a total heat recovery type fresh air purification system based on a nano fluid. The system comprises a fresh air treatment module and a return air treatment module, wherein thefresh air treatment module comprises a compound photocatalytic module, a bubbling photocatalytic module, a filler sterilizing module and a washing and defogging module. The return air treatment module comprises a return air bubbling module and a return air spraying and heat exchanging module. Outdoor air treated by the fresh air treatment module enters indoors and indoor return air treated by thereturn air treatment module is introduced outdoors. The system converts conventional gas-gas heat exchange between fresh air and return air into gas-nano fluid-gas heat exchange and synergically utilizes photocatalytic degradation of organic pollutants of TiO2 nanoparticles and strong sterilizing action of Ag nanoparticles. By switching an indoor purification mode and a fresh air purification mode, the purification system suitable for indoor air pollution and outdoor air pollution simultaneously 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.
