This utility model discloses a radiating facility absorbing residual electron beam, in the field of radiating processing technology. The utility model comprises electric straight line accelerating, electron beam shifting scanning frame connected with electron beam connected with electron straight line accelerator, which is arranged under electron beam shifting scanning frame, and electron beam absorber is fixed at the bottom of mechanical transfer mechanism. The electron beam absorber is connected with electric line accelerator, forming electronic circuit, so as to enable heat transfer. Using this utility model, the thickness of protection layer in the electron beam radiating facility can be lowered, so as to save cost and reduce dimension and weight, prevent partial accumulation of charge and heat, realize automatic screening and small scale of electron beam, and further enlarge the application scope of electron beam radiating facility.
