The air purification method and the device do not cause external space peculiar smell and secondary pollution, and can also adjust the temperature and humidity of air, because the air is introduced into the sodium hypochlorite solution, but the traditional disinfectant is directly sprayed into the air, the sodium hypochlorite solution can not be directly dissolved in the air, concretely, because the air is heated and sterilized by the high-temperature water bath of the heating and sterilizing unit 1, the heated air is then introduced into the sodium hypochlorite solution of the chlorination and sterilizing unit 2, the novel coronavirus carried in the air is subjected to the chlorination activity reduction of the sodium hypochlorite in the solution, meanwhile, partial heat in the air is transferred into the sodium hypochlorite solution, the air humidity is also increased under the action of the sodium hypochlorite solution, the sodium hypochlorite is thermally decomposed, according to the chemical reaction formula NaClO → NaCl + O2Sodium hypochlorite is heated and decomposed into sodium chloride (main component of salt) and oxygen, so that no peculiar smell is generated, and the oxygen content in the air is increased; the air outlet of the chlorination disinfection unit 2 is arranged at the top of the chlorination shell 21, air in the top space of the sodium hypochlorite solution is collected by the outlet air, the air is not collected due to the fact that the air is close to the liquid level of the sodium hypochlorite solution under the action of gravity, and a small amount of sodium hypochlorite solution exists in the air with high humidity, so that the peculiar smell of the sodium hypochlorite solution does not exist in the outlet air of the chlorination disinfection unit 2; and the air circles round from top to bottom through the corridor type air channel structure 33 and is fully contacted and disinfected with the ultraviolet lamp 32, the temperature and humidity of the air are further adjusted, even if a small amount of sodium hypochlorite micro aerosol exists in the air, the micro aerosol can be decomposed into sodium chloride and oxygen under the irradiation of the ultraviolet lamp 32, the hypochlorous acid which stimulates the respiratory tract of the human body is further ensured not to be generated, and therefore the final air outlet quality safety is guaranteed.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
