Description

Technical Field

[0001] The utility model relates to the technical field of high-energy electron accelerator irradiation, in particular to a device for forcibly discharging odor under high-energy electron beam irradiation. Background Art

[0002] When a high-energy electron accelerator is irradiating, the oxygen in the air will produce ozone after being irradiated. Due to the strong oxidizing property of ozone, a high ozone concentration will cause different degrees of electron acceleration damage to various electrical components or machine parts in the beam irradiation room. The existing beam exhaust is usually an integral exhaust device, that is, a unified ventilation and exhaust device is used in the device where the entire irradiation room is located. Although it is generally exhausted to the outside, it is impossible to centrally force ventilation and exhaust the beam irradiation area where ozone is generated, which poses certain safety hazards. For this reason, we propose a device for forced emission of odor under high-energy electron beam irradiation. Utility Model Content
