Description

Technical Field

[0001] The utility model belongs to the technical field of industrial electron accelerator irradiation processing, and in particular relates to an ultra-high-dose electron beam irradiation processing system for products. Background Art

[0002] The electron bunch emitted by the industrial electron accelerator reaches a vertical plane at a certain distance along the acceleration direction, usually forming a circular beam spot with a certain diameter (about 2 to 10 cm), and its electron density distribution is normally distributed (or nearly normally distributed) from the center of the circle to the outside; after the completion of acceleration, the high-frequency repeatedly emitted electron beam spot is reciprocated and deflected and scanned within a certain angle range with the acceleration direction under the action of the scanning magnetic field, and arranged and partially overlapped on the above vertical plane to form an "electron beam belt". The electron beam scanning method commonly used by the current industry is triangular wave reciprocating constant speed scanning. On the electron beam belt with a certain width formed by this, the electron beam density is symmetrically distributed in the scanning direction with the line perpendicular to the scanning direction and located in the acceleration direction (the center beam spot diameter perpendicular to the scanning direction) as the reference line, and is normally distributed (or nearly normally distributed) in the bandwidth direction with the center line of the electron beam belt (the line formed by the center of the electron beam spot in the scanning direction) as the reference line.

[0003] According to the electron acceleration direction, industrial electron accelerators are usually set upright or horizontally, and the corresponding electron beams are vertical beams and horizontal beams. In industrial irradiation processing applications, the irradiated products generally have a certain surface area, volume, and weight. According to public information and actual industry investigations, for vertical beam irradiation processing, the product is usually conveyed by a beam conveyor and passes through or remains in the electron beam scanning area several times to receive a certain dose of electron beam irradiation.

[0004] For products that are irradiated under the electron beam belt and receive a certain dose of electron beam irradiation, products that require an irradiation dose of less than several thousand kiloGrays can generally reach the cumulative dose requirement (a few tenths to several thousand kiloGrays) by irradiating the electron beam scanning area one to dozens of times periodically. Suitable beam conveying devices are plate chain conveyors, roller conveyors, gear conveyors, toothed chain conveyors, and rail trolley conveyor systems. The passing cycle is about tens of minutes and the cumulative online time is generally not more than tens of hours. For products with extremely high cumulative dose requirements (tens of thousands or even millions of kiloGrays) and extremely high cumulative electron irradiation flux requirements (such as diamonds, topaz, semiconductor wafers, metal materials, inorganic materials, etc.), it is possible to meet the requirements after thousands of passing irradiations. Considering the processing completion time of a single (batch) product in actual production, the irradiation treatment is generally carried out by static irradiation in the electron beam scanning area under the electron beam belt for a long time (tens of minutes to hundreds of hours).

[0005] The farther the plane where the cross-sectional plane of the irradiated product is located, which is perpendicular to the electron acceleration direction, is from the accelerator scanning window, the larger the diameter of the electron beam spot reaching the plane, that is, the larger the width of the electron beam band. For an industrial electron accelerator irradiation device set upright, generally due to the distance and space limitation between the accelerator scanning window and the ground, the width of the electron beam band reaching the product surface on the two-dimensional cross-sectional plane perpendicular to the electron acceleration direction does not exceed 10 cm, and the electron density is normally distributed (or nearly normally distributed) in the bandwidth direction. As a result, when a product of a certain size is placed under the electron beam coverage area for static irradiation, there must be inherent irradiation dose non-uniformity in the bandwidth direction, which can easily cause a certain proportion of product damage or uneven irradiation effects. In industrial practice, in order to reduce the irradiation dose non-uniformity of static irradiation of products, it is generally necessary to control the product size to be lower than the electron beam band width, and to supplement it with stirring (for example, when irradiating powdery inorganic materials and granular diamonds) or rotation (for example, when irradiating wafer semiconductor materials, metal plates, and ceramic sheets whose sizes are close to or larger than the electron beam band width) and other measures. Such measures require starting and stopping the accelerator equipment multiple times, which can easily lead to accelerator equipment failure, long equipment occupancy time, low electron beam utilization rate, and limited improvement in the product's irradiation dose non-uniformity. It is difficult to accurately control and evaluate the irradiation dose, and the irradiation process has poor stability and repeatability.

[0006] In summary, in the technical field of using industrial electron accelerators for ultra-high-dose electron beam irradiation treatment of products, there is an urgent need for a system that is high-efficiency, highly reliable, has low irradiation dose non-uniformity, and can be used for continuous large-scale processing of products in a wide size range from millimeters to meters.
