Embodiment 1

[0019] Embodiment 1: a kind of fresh air evolution system, the steps are:

[0020] (a) Introduce fresh air by fans and provide power support for fresh air and subsequent processes;

[0021] (b) The fresh air is transported through the air duct to the primary filter for primary filtration, and the primary filter is a medium-efficiency filter that can filter particles of impurities above 1 μm;

[0022] (c) The filtered air is transported through the air duct to the air storage disinfection tank for mixing and disinfection of air and ozone;

[0023] (d) The mixed gas is pumped into the pressure tank for storage;

[0024] (e) The sterilized air contains a relatively high concentration of ozone and needs to be decomposed. Here, a heating device is used to decompose ozone at high temperature;

[0025] (f) When the decomposed mixed gas is passed into the water bath through the trachea, part of the harmful gas reacts with the water, and the product is discharged by the water, and th...

Embodiment 2

[0031] Embodiment 2: On the basis of the above-mentioned embodiment 1, in this embodiment, the gas storage disinfection step gas storage and disinfection are carried out in the same pressure vessel, and the gas storage disinfection tank is used as a pressure vessel, preferably a medium pressure vessel, and its pressure resistance should be Exceeding 5MPa, the concentration of ozone is preferably greater than 25ppm, and the disinfection time is preferably 30min. It can not only disinfect, but also oxidize air pollutants such as carbon monoxide and carbon dioxide in the air, and react with water or dissolve in water when it flows through the water.

Embodiment 3

[0032] Embodiment 3: On the basis of the above embodiment 1, in this embodiment, the gas storage step is carried out in another pressure vessel. The gas storage tank for this step is a high-pressure gas storage tank, the pressure resistance requirement is greater than 10MPa, and the gas passes through the valve slowly. Discharge to high temperature deodorization place to treat ozone.

Abstract

The invention discloses a fresh-air air purification process. The fresh-air air purification process mainly includes the process steps of fresh air, primary filtration, gas storage disinfection, gas storage, high temperature deodorization, water bath impurity-removing and deodorization, refrigeration dehumidification, secondary filtration, detection, tertiary filtration, detection and discharge topurify fresh air, and the problems that part of bacteria which is not removed completely and is carried by fresh air can breed after entering a room, it is difficult to guarantee the bacteria-free requirement of the environment where people are not suitable to leave after entering or in special places where disinfection or sterilization is not easy to use are solved. The fresh air disinfects or sterilizes the air before discharging, so that the part of the bacteria which is not removed completely and is carried by the fresh air is killed before entering the room, the problem that after the fresh air is discharged into the room and bacteria grows in the room is solved, and the bacteria-free requirement of the environment where people are not suitable to leave after entering or in the special places where disinfection or sterilization is not easy to use is guaranteed.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a fresh air purification process. Background technique [0002] In today's air purification, multi-stage filters are often used to purify the space. Many air disinfections mostly use filters or ozone sterilization. Among them, ozone sterilization is the most widely used air sterilization technology, and most of them use In factories and hospitals in the medical industry, most of them are disinfected or sterilized without people, and then fresh air is introduced after disinfection or sterilization. In this way, some of the bacteria that have not been eliminated by the fresh air are in the air. It can reproduce after entering the room. It is difficult to guarantee the aseptic requirements of the environment in rooms where some personnel are not suitable to leave after entering or in special places where disinfection or sterilization is not easy to use. For this reason, a fresh air...
