Fig. 1 is a structural principle diagram of the air disinfection device described in the utility model.

Implementation method

The technical solution of the utility model, its working principle and advantages will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the high-efficiency dynamic continuous air disinfection device described in the utility model mainly includes a regular packing disinfection tower 5, an air inlet 1 is arranged at the bottom of the disinfection tower 5, and a high-efficiency air inlet 1 is arranged at the middle of the disinfection tower 5 The mass transfer element 2 is provided with a liquid distributor 3 above the high-efficiency mass transfer element 2, and the disinfectant inlet 7 is provided above the liquid distributor 3. The demister 4 is provided with an air outlet 6 above the demister 4. In this embodiment, a structured packing deagent tower 8 is also provided, and the air outlet 6 of the disinfection tower 5 is connected with the air inlet 15 arranged at the bottom of the deagent tower 8, and a transmission device is arranged in the middle part of the deagent tower 8. The mass element 13 is provided with a liquid distributor 12 above the mass transfer element 13, the absorbent inlet 11 is arranged above the liquid distributor 12, and a demister 10 is also provided above the liquid distributor 12. The top of 10 is provided with air outlet 9. In this embodiment, the mass transfer elements 2 and 13 used in the disinfection tower 5 and the deagent tower 8 are both corrugated structured packings, and the surface area of the corrugated structured packings is 50m ² /m ³ -1000m ² /m ³ .

The working principle of the air disinfection device of the above structure is as follows: the air to be sterilized is introduced into the bottom of the disinfection tower 5 through the air inlet 1 of the disinfection tower 5 at a certain flow rate with an induced draft fan, and at the same time, the disinfectant circulation pump 17 is started, and The disinfectant is delivered to the liquid distributor 3 through the disinfectant inlet 7. In the present embodiment, assuming that peracetic acid is used as the disinfectant, the effect of the liquid distributor 3 is to evenly distribute the flow of the disinfectant; Under the action of the disinfectant, the disinfectant enters the high-efficiency corrugated structured packing 2 from top to bottom, and forms a uniform liquid film flowing from top to bottom on the surface of the high-efficiency corrugated structured packing 2. In the high-efficiency corrugated structured packing 2, by The top-down disinfectant and the bottom-up air continuously move countercurrently in an artificially set Z-shaped curve, so that bacteria and viruses in the air are effectively killed. The effect of the demister 4 is to remove the liquid phase in the air, and the sterilized air flows out of the disinfection tower 5 through the air outlet 6 . Because the sterilized air may contain a certain concentration of disinfectant, which will cause side effects on the human body’s respiratory tract and other organs, and will also cause secondary pollution to the environment. Therefore, in this embodiment, a structured packing remover is also provided. Tower 8, its principle of action is: the air that comes out from disinfection tower 5 is introduced into the bottom of structured packing deagent tower 8 through air inlet 15 again, simultaneously, start absorbent circulating pump 14, and will absorb through absorbent inlet 11 The agent is delivered to the liquid distributor 12. In this embodiment, if peracetic acid is used as the disinfectant, water is used as the absorbent; in the same way, the function of the liquid distributor 12 is to evenly distribute the flow of the absorbent ; Under the action of gravity, the absorbent enters the high-efficiency corrugated structured packing 13 from top to bottom, and forms a uniform liquid film flowing from top to bottom on the surface of the high-efficiency corrugated structured packing 13. In the process, the absorbent from top to bottom and the air from bottom to top continuously move countercurrently in an artificially set Z-shaped curve, so that the disinfectant contained in the air is effectively absorbed and clean air is achieved. For the purpose, clean air flows out through the air outlet 9. The function of the demister 10 is to remove the liquid phase in the air.

In actual use, the disinfectant circulation pump 17 and the absorbent circulation pump 14 can also be connected to each other, and a valve 16 is set in the connecting pipeline, and the disinfectant circulation pump 17 can also be communicated with the bottom of the disinfection tower 5, The absorbent circulation pump 14 is communicated with the bottom of the deagent tower 8; this can improve the utilization rate of the disinfectant and reduce the use cost.

In actual use, the air disinfection device described in the utility model can be applied to the air circulation device of the air-conditioning system of the relevant place, and it can also be directly applied to the place that needs to be disinfected and sterilized, and can continuously and effectively disinfect the relevant places. The indoor air is disinfected, which greatly reduces the probability of people who are active in these places being infected by viruses or bacteria in the air, and protects people's health.
