[0029] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] See Figures 1 to 6 This embodiment provides an electron accelerator, which includes an acceleration tube 31, a scanning box 21, and a liquid processing device 11.

[0033] The liquid handling device is an electron beam irradiation device used to transfer liquids or sewage to be disinfected.

[0034] The liquid treatment device includes an inlet pipe interface, an outlet pipe interface, and a main body. The inlet pipe interface is connected to the inlet pipe 41 of the liquid to be disinfected, and the outlet pipe interface is connected to the outlet pipe 51 of the liquid to be disinfected.

[0035] The main body of the device includes a first cavity 111, a second cavity 112, and an irradiation seat 113. The irradiation seat 113 is provided with a channel and connects the first cavity 111 and the second cavity 112. The irradiation seat is installed below the electronic outlet of the scanning box.

[0036] The first cavity 111 is connected to the water inlet pipe interface 114. The height of the first cavity 111 decreases and the width increases along the water inlet direction.

[0037] The second cavity 112 is connected to the water outlet interface 115. The height of the second cavity 112 increases and the width decreases along the water inlet direction.

[0038] The main body of the device in this embodiment is an irregularly shaped cavity, which serves as a channel for transmitting the irradiated liquid. Its main features are:

[0039] The longitudinal section of the cavity transitions from a circular shape near the pipe at the liquid inlet to a long strip shape below the irradiation window, aiming to minimize the liquid thickness in the irradiated area. During this cross-sectional change, the width of the profile gradually increases while the thickness decreases, maintaining a relatively constant cross-sectional area to reduce resistance to water flow.

[0040] The first cavity, the channel of the irradiation seat, and the second cavity are connected in sequence, and their shells can be a one-piece molded structure.

[0041] The front side of the channel of the irradiation seat 113 is connected to the first cavity 111 and the rear side of the channel is connected to the second cavity 112.

[0042] The top of the irradiation holder 113 is provided with a connecting protrusion 1131, the upper surface of the connecting protrusion is provided with a cavity titanium foil 1132, and the channel 1133 is located below the cavity titanium foil.

[0043] The cavity contains a rectangular irradiation area for the irradiation seat, above which a thin titanium sheet (cavity titanium foil) is welded. A high-energy electron beam can penetrate the titanium sheet and enter the closed cavity.

[0044] The scanning box 21 has a titanium window 211 at the electronic outlet position. The connecting protrusion protrudes from the upper surface of the outer shell of the first cavity 111 and the second cavity 112, and the upper surface is parallel to the horizontal plane.

[0045] The shape (size) of the protruding portion of the connecting protrusion 1131 matches the shape of the electronic outlet of the scanning cartridge. The protruding portion of the connecting protrusion is embedded in the recess of the window of the electronic outlet.

[0046] With the irradiation mount and the lower flange 212 of the scanning box fixed, the titanium foil 1132 of the cavity is bonded to the titanium foil of the titanium window.

[0047] The raised irradiation mount ensures close contact between the titanium foil and the titanium foil exit window at the bottom of the electron beam scanning box. This design aims to utilize a high-speed liquid flow to remove the significant waste heat generated by the electron beam impacting the titanium foil, thereby extending the foil's lifespan.

[0048] The bottom of the irradiation seat 113 is provided with a bottom arc-shaped protrusion 1134, the channel 1133 is above the bottom arc-shaped protrusion 1134, and a tungsten base plate 1135 is provided below the bottom arc-shaped protrusion. The upper surface of the tungsten base plate matches the shape of the bottom arc-shaped protrusion.

[0049] A tungsten base plate is installed at the bottom of the cavity, corresponding to the beam window position. It serves two purposes: first, it blocks the remaining electron beam energy, providing shielding protection; second, after some electrons collide with the tungsten, they generate X-rays that are reflected upwards, irradiating the liquid flow more effectively and maximizing energy utilization.

[0050] Along the water inlet direction, the cross-sectional height of the first cavity 111 decreases uniformly and the cross-sectional width increases uniformly.

[0051] Along the water inlet direction, the cross-sectional height of the second cavity 112 increases uniformly and the cross-sectional width decreases uniformly.

[0052] Both the first cavity and the second cavity have hexagonal cross-sections.

[0053] The upper surface of the first and second cavity shells is provided with mounting parts 1136 that are fixed to the scanning box flange.

[0054] The inner wall of the irradiation chamber has a smooth transition, and the middle of the cavity has a rounded smooth transition to minimize water flow resistance.

[0055] A fixing frame 116 is provided above the mounting component to fix the titanium foil in the cavity. The fixing frame and the mounting component clamp the titanium foil in the cavity.

[0056] The upper surface of the first cavity and the outer shell of the second cavity is provided with a water tank 117. The mounting component is located at the bottom of the water tank. The side of the water tank is provided with a cooling water inlet 1171 and a cooling water outlet 1172. The height of the cooling water outlet is greater than the height of the titanium foil of the cavity.

[0057] Due to air pressure, the curved shapes of the titanium foil in the cavity and the titanium foil in the beam exit window cannot be completely determined. Therefore, in practical applications, the two titanium foils are difficult to fully adhere, resulting in uneven heat conduction and limited conduction efficiency. To solve this problem, a surrounding plate is installed above the middle of the cavity, forming a water tank around the beam exit window. This water tank is an integral part of the cavity, with inlet and outlet ports at both ends. The outlet is positioned high, allowing the lower flange of the scanning box to be completely submerged, ensuring that the protruding titanium foil in the cavity and the titanium foil in the beam exit window are completely submerged together. When the water tank is filled with cooling water, the water can fill the gaps between the two titanium foils that are not fully adhered, enabling effective heat conduction between them. Simultaneously, the flowing water also provides further cooling.
