Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and implementation process.

[0021] like Figure 1-Figure 5 As shown, the carbon-replaceable iodine removal filter device provided by the present invention includes a metal shell 1 and an activated carbon adsorbent placed in the metal shell 1 . Among them, the metal shell 1 is provided with several V-shaped perforated metal folding plates 5, 6, and the V-shaped perforated metal folding plates are provided with several supporting brackets 3 inside, and the V-shaped perforated metal folding plates pass through the folding plates. The fixed frame 8 is fixed on the metal shell. The opening directions of the two adjacent V-shaped perforated metal folding plates 5 and 6 are respectively facing the air inlet surface and the air outlet surface, and a plurality of V-shaped perforated metal folding plates with the same opening direction are arranged at intervals in this way. A...

Abstract

The invention relates to purification equipment for iodine, in particular to an iodine removing filter device with replaceable carbon. The iodine removing filter device structurally comprises a metal shell and activated carbon adsorbent placed in the metal shell. A plurality of V-shaped through hole metal folding plates are arranged in the metal shell, a parallel space is formed between every two adjacent V-shaped hole penetrating metal folding plates, and the activated carbon adsorbent is placed in the parallel spaces. A side wall baffle is arranged between the two ends of every two adjacent V-shaped hole penetrating metal folding plates, the side wall baffles and the metal shell are welded at the angle of 90 degrees in a sealing mode, and the edges of the two ends of the V-shaped hole penetrating metal folding plate which corresponds to an intake air face are surrounded. The iodine removing filter device effectively reduces the friction-resistance ratio, effectively lowers wind resistance, and meanwhile solves the problem that the improvement of purification coefficients is influenced by a side wall effect.

Description

technical field [0001] The invention relates to purification equipment for removing iodine in gas form in the field of nuclear industry and nuclear technology application, in particular to an iodine removal filter device capable of replacing carbon. Background technique [0002] In order to ensure the safe operation of military and civilian nuclear facilities, airborne radioactive iodine gas needs to be adsorbed, and foldable iodine adsorbers are usually used. The structure of the foldable iodine adsorber includes a metal shell and an activated carbon adsorbent placed in the metal shell. There are several V-shaped perforated metal folded plates inside the metal shell, and two adjacent V-shaped perforated metal folded plates are formed. In the parallel space, the activated carbon adsorbent is placed in the parallel space, see Chinese patent 201220388864.1 "Folding Iodine Adsorber". However, the original foldable iodine adsorber is affected by the side wall effect, and there ...
