Non-chain df/hf laser discharge products miniaturized dry processing device

Abstract

The invention discloses a non-chain-type DF / HF laser discharge product small-scale dry-treatment device and belongs to the technical field of laser discharge product treatment. 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.

Description

technical field

[0001] The invention relates to the technical field of treatment of laser discharge products, in particular to a non-chain type DF / HF laser discharge product miniaturized dry processing device. Background technique

[0002] The output band of the non-chain deuterium fluoride / hydrogen fluoride (DF / HF) laser is 2.6-4.1 μm, which is in the mid-infrared band of 3-5 μm. This band is not only the atmospheric infrared window with the smallest attenuation, but also covers the absorption peaks of many atoms and molecules in this band. Therefore, lasers in this band are important in many fields such as spectroscopy, remote sensing, medical treatment, environmental protection, and military affairs. application value and prospects. In view of the similar physical and chemical properties of the working gas and discharge generation of the non-chain DF laser and the HF laser, only the non-chain DF laser is used as an example for illustration.
