Technical Field

[0001] The present invention relates to the field of air purification, and in particular to a fresh air purification system. Background Art

[0002] In today's air purification systems, multi-stage filters are often used to achieve space purification. Many air disinfections use filters or ozone sterilization. Among them, ozone sterilization is the most widely used air sterilization technology, mostly used in factories and hospitals in the medical industry. However, most of them are carried out in the absence of people. Therefore, it is relatively difficult to disinfect the air in some rooms where people should not leave after entering or in special places where disinfection is not easy. If other sterilization methods are used, the desired effect may not be achieved, making air purification more difficult. To this end, a fresh air purification system is provided.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Example 1: Figure 1 and Figure 2 The fresh air purification system shown is mainly composed of eight sections: a shell 37, a fresh air box 4, a gas storage tank 7, a high-temperature deodorizer 29, a water tank 12, a refrigeration dehumidifier 15, an intermediate filter 21, a first detection device 16, and a high-efficiency filter 17. The sections are connected by air ducts, and a throttle valve is provided on each air duct. The shell 37 serves as a protective cover that wraps the entire fresh air purification system. The left side of the shell 37 is provided with an air inlet 1 connected to the fresh air box 4, and a gauze 2 is provided inside the air inlet 1. The right side of the shell 37 is provided with an air outlet 19 connected to the first detection device 16 and the second detection device 18; the gas storage tank 7 is provided with an upper gas tank section 8 and a lower gas tank section 11. The bottom center of the upper gas tank section is fixed with an arc groove 31 with an upward notch. The top of the upper gas tank section 8 is provided with an air pump 9. The air inlet of the air pump 9 is connected to the fresh air box 4, and the air outlet of the air pump 9 is connected to a small air duct 10. The small air duct (10 )'s air outlet is suspended in the groove of the arc groove 31, and the arc groove 31 mainly makes the wind blown out of the small air duct 10 present a uniform flow and diffusion; an ozone nozzle 30 is arranged in a ring on the inner wall of the upper section 8 of the gas storage tank above the arc groove 31, and the ozone nozzle 30 is connected to the ozone generator 6. The nozzle sprays ozone towards the uniformly diffused wind phase to merge with each other to achieve disinfection; the upper and lower sections of the gas storage tank 7 are separated by a partition, and a valve is provided on the partition to connect the upper and lower sections. The lower section 11 of the gas storage tank is connected to the high-temperature deodorizer 29. The upper section is mainly used for mixed disinfection, and the lower section is mainly used for gas storage. While ensuring sufficient disinfection, it also ensures that the system can continuously supply gas.

[0024] The high-temperature deodorizer 29 is composed of an outer shell and a heating tube 27 arranged in the outer shell. A plurality of heating nets 26 are arranged in the middle of the heating tube 27. The heating nets 26 are woven with heating wires. The high-temperature deodorizer 29 is connected to the bottom of the water tank 12. The air mixed with ozone flows into the high-temperature deodorizer through the air duct and is decomposed by the high temperature. Here, the temperature of the high-temperature deodorizer is selected between 100°C and 200°C, preferably 120°C. Too low a temperature is not conducive to the decay of ozone, and too high a temperature is not conducive to the placement of the equipment.

[0025] The water tank 12 includes a water inlet pipe 23, a water outlet pipe 24, a water mist nozzle 13 and a U-shaped air duct 14. The water inlet pipe 23 and the water outlet pipe 24 are arranged in the middle and lower part of the water tank 12, the water mist nozzle 13 is arranged on the top inner wall of the water tank 12, and the U-shaped air duct 14 connects the top of the water tank 12 and the refrigeration dehumidifier 15. The refrigeration dehumidifier (15) is connected to the intermediate filter (21); the first detection device 16 is connected to the high-efficiency filter 17, the air outlet 19, and the high-temperature deodorizer 29 respectively through a three-way branch pipe. A second detection device 18 is arranged between the end of the high-efficiency filter 17 and the air outlet 19. The second detection device 18 is connected to the air outlet 19 and the high-temperature deodorizer 29 respectively through a two-way branch pipe.

[0026] The air deodorized by the high-temperature deodorizer 29 comes to the water tank 12 and flows upward from the bottom of the water tank 12. At the same time, water is continuously passed through the water tank 12 to dissolve the residual odor and excess oxygen into the water and take them away. The U-shaped air duct 14 is mainly provided to condense the water carried by the air coming out of the water tank 12 and then flow into the refrigeration dehumidifier 15. After refrigeration and dehumidification, it becomes clean air and flows into the next stage of medium-efficiency filtration for filtration. The filtered clean air passes through the first detection device and flows into the room after passing the inspection. If the inspection fails, it is checked according to the unqualified items whether it can meet the requirements after high-efficiency purification. If not, it returns to different devices. The main inspection items are PM, temperature and humidity, ozone content, and microbial limit. When PM and temperature and humidity fail to meet the requirements, it is processed by the high-efficiency filter, and then tested again after the high-efficiency filter treatment, and then discharged. When the ozone content test fails, it flows to the high-temperature deodorizer for further treatment. When the microbial limit fails, it flows to the upper part of the gas storage tank for disinfection again. This cycle is repeated until it is qualified for discharge.
