The device solves the problem that the existing laser tail gas treatment device has a large structure, complex adsorbent loading and unloading processes influencing with each other, is inconvenient for storage and transport, and produces environmental pollution. The device comprises a metal casing and one or more sealed purification units. Each one of the one or more sealed purification units comprises a gas inlet pipe, a gas outlet pipe, and an adsorbent storehouse chamber composed of a first transition storehouse chamber, a first storehouse chamber, a second storehouse chamber, a third storehouse chamber and a second transition storehouse chamber orderly arranged from bottom to top. The metal casing is respectively provided with filler openings communicated with the first storehouse chamber, the second storehouse chamber and the third storehouse chamber. The filler openings are respectively used for filling and discharging the adsorbent in the first storehouse chamber, the second storehouse chamber and the third storehouse chamber. Sealing covers for sealing the filler openings are arranged on the filler openings. The device has the advantages of thorough product treatment, small equipment volume, light weight, operation easiness, maintenance convenience and no secondary pollution waste water.
