[0022] Please also read Figure 1 and Figure 2Now, the industrial radiation accelerator ozone cycle treatment purification equipment provided by the present invention is described.

[0023] The ozone cycle treatment and purification equipment for industrial irradiation accelerator includes not only a shielding body, an industrial irradiation accelerator, a scanning window 1 and a beam conveying device 2, but also a water tank 3, an air inlet pipe 4, a vent pipe 5 and an exhaust fan. The water tank 3 is arranged in the shielding body, and the water tank 3 is fixedly arranged directly below the scanning window 1 of the industrial irradiation accelerator. The beam conveying device 2 is arranged between the water tank 3 and the scanning window 1. The water tank 3 is used to hold water. One end of the air inlet pipe 4 is connected to the side wall of the water tank 3, and the other end of the air inlet pipe 4 is connected to one side of the beam conveying device 2 to extract ozone; the vent pipe 5 is arranged in the water tank 3, and a plurality of through holes 51 are arranged on the vent pipe 5, and one end of the vent pipe 5 is connected to the air inlet pipe 4. The exhaust fan is arranged on one side of the water tank 3, and the exhaust fan is connected to the air inlet pipe 4.

[0024] Compared with the prior art, the industrial irradiation accelerator ozone cycle treatment purification equipment provided in this embodiment includes a shield, an industrial irradiation accelerator, a scanning window 1 and a beam conveying device 2, and further includes a water tank 3, an air inlet pipe 4, a vent pipe 5 and an exhaust fan. The electrons generated by the industrial irradiation accelerator pass through the scanning window 1 for beam outflow (i.e., beam out). When the beam-out electrons (i.e., electron beams) irradiate and sterilize the items on the beam conveying device 2, the electrons and the air will generate ozone and nitrogen oxides. At the same time, because the water tank 3 is arranged directly below the scanning window 1, the electrons react with water to generate reducing hydrated electrons and hydrogen free radicals. The exhaust fan draws the generated ozone into the ventilation pipe 5 through the air inlet pipe 4, so that the ozone is injected into the water through the through hole 51 on the ventilation pipe 5. Since ozone has strong oxidizing properties, it can undergo redox reactions with reducing radicals generated in water, and finally generate water and oxygen, thereby solving the technical problem of the prior art that ozone is directly discharged into the atmosphere and easily causes air pollution.

[0025] Furthermore, the width of the water tank 3 is greater than the width of the scanning window 1 of the industrial irradiation accelerator.

[0026] Furthermore, the spacing between the rollers 21 in the under-beam conveying device 2 is greater than the width of the scanning window 1, which can reduce the shielding effect of the electron beam received by the water body due to the small gap between the rollers 21 during the conveying process.

[0027] As a specific embodiment, the height of the water in the water tank 3 is not less than 6 cm.

[0028] In some embodiments, in order to allow water and ozone to be fully mixed and contacted so that the reducing hydrated electrons and hydrogen radicals can undergo a redox reaction with the ozone, a turbulence unit 6 is provided in the water tank 3 .

[0029] For further information, see Figures 2 to 4 In the first embodiment, the spoiler unit 6 includes a connecting pipe 61, a sleeve 62 and an umbrella cover 63. The connecting pipe 61 is vertically arranged in the water tank 3, and the bottom of the connecting pipe 61 is connected to the vent pipe 5; the sleeve 62 is sleeved on the top of the connecting pipe 61; the umbrella cover 63 is rotatably arranged on the top of the sleeve 62, and the umbrella cover 63 is provided with a first cavity 631, which is connected to the connecting pipe 61, and an air hole 632 is provided on the umbrella cover 63. The air hole 632 is arranged in a spiral and inclined manner along the rotation direction of the umbrella cover 63.

[0030] Since the first cavity 631 in the umbrella cover 63 is connected to the vent pipe 5 through the connecting pipe 61, the ozone passes through the vent pipe 5, the connecting pipe 61, and the first cavity 631 in sequence, and is finally discharged into the water through the air holes 632. Since the air holes 632 are arranged in a spiral inclination along the rotation direction of the umbrella cover 63, when the ozone passes through the air holes 632, thrust is generated, thereby pushing the umbrella cover 63 to rotate in the sleeve 62. When the umbrella cover 63 rotates, the water in the water tank 3 is stirred, which is conducive to the redox reaction between the reducing hydrated electrons and hydrogen free radicals and the ozone.

[0031] Furthermore, the spoiler unit 6 also includes a plurality of blades 64, which are arranged at intervals on the top of the umbrella cover 63 along the circumference of the umbrella cover 63; the blades 64 are provided with a second cavity 641, and the first cavity 631 is connected to the second cavity 641, and a vent hole 642 is provided on the side wall of the blade 64.

[0032] The second cavity 641 in the fan blade 64 is connected to the first cavity 631 , and a vent hole 642 is provided on the side wall of the fan blade 64 to facilitate the rotation of the fan blade 64 . Specifically, the vent hole 642 is provided on the arc-shaped inner side wall of the fan blade 64 .

[0033] The fan blades 64 can make the umbrella cover 63 stir the water in the water tank 3 to a greater extent during the rotation process, so as to enhance the rapid reaction of ozone with hydrated electrons and hydrogen radicals.

[0034] See also Figure 5 and Figure 6 In Example 2, the spoiler unit 6 includes a spoiler tube 65 , a rotating shaft 66 and a plurality of spoiler blades 67 .

[0035] The spoiler tube 65 is arranged on the ventilation tube 5, and the spoiler tube 65 is connected to the ventilation tube 5; the rotating shaft 66 is sleeved on the top of the spoiler tube 65, and the rotating shaft 66 and the spoiler tube 65 are rotatably connected through a bearing; a plurality of spoiler blades 67 are arranged on the rotating shaft 66, and the outer diameter of the spoiler blades 67 is larger than the outer diameter of the spoiler tube 65.

[0036] Ozone passes through the spoiler tube 65 and finally flows through the spoiler blade 67. The spoiler blade 67 rotates in the water under the action of the airflow, thereby increasing the reaction probability of ozone with hydrated electrons and hydrogen radicals.

[0037] Furthermore, a plurality of spiral spoiler grooves 651 are provided on the inner wall of the spoiler tube 65. The spiral spoiler grooves 651 can accelerate the air passing through the spoiler grooves 651, thereby increasing the blowing intensity of the airflow.

[0038] Furthermore, the spoiler tube 65 is a truncated cone structure, and the top diameter of the spoiler tube 65 is smaller than the bottom diameter of the spoiler tube 65 , so that the speed of the airflow out of the spoiler tube 65 is greater than the speed when entering the spoiler tube 65 .

[0039] On the basis of the above embodiment, a plurality of flow disturbance units 6 are provided on the ventilation pipe 5. The provision of the plurality of flow disturbance units 6 improves the contact reaction process of ozone with hydrated electrons and hydrogen radicals.

[0040] Furthermore, the through hole 51 is arranged obliquely.

[0041] In a second aspect, an industrial radiation accelerator ozone cycle treatment purification method adopts the radiation accelerator ozone cycle treatment purification equipment of the above embodiment, characterized in that: S1, when the electrons emitted from the scanning window 1 irradiate and sterilize the articles on the conveying device 2 under the beam, the electrons react with the air to generate ozone and nitrogen oxides; S2, the water tank 3 is set just below the scanning window 1, and the electrons react with water to produce hydrated electrons and hydrogen free radicals with reducing properties (the following is the reaction equation of electrons and water);

[0042] S3, the exhaust fan sucks the generated ozone into the ventilation pipe 5 through the air inlet pipe 4, and the ozone is injected into the water through the through hole 51 on the ventilation pipe 5. Since ozone has strong oxidizing properties, ozone undergoes redox reactions with hydrated electrons and hydrogen free radicals with reducing properties, and finally generates water and oxygen (the following is the redox equation);

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
