Detailed Description
As shown in fig. 1 to 4, an integrated housing and large-filtration-area iodine adsorber structure comprises a stainless steel box shell 1 and an activated carbon fiber felt 2 arranged in the stainless steel box shell 1, wherein the cross section of the stainless steel box shell 1 is concave, one side of the stainless steel box shell 1 is welded and fixed with an iodine adsorber panel 6, the other side of the stainless steel box shell is welded and fixed with a support plate 7, an air inlet 4 is formed in the iodine adsorber panel 6, a wind shield 8 is arranged at the inner side of the air inlet 4, and an air outlet 3 is formed in the opening surface of the stainless steel box shell 1;
the activated carbon fiber felt 2 is folded into a continuous S shape through a paper folder, two opposite side faces of the activated carbon fiber felt 2 are respectively connected with the inner side faces of the wind shield 8 and the support plate 7 in a sealing mode through pouring silica gel, and the other two opposite side faces of the activated carbon fiber felt 2 are respectively connected with two inner side faces of the stainless steel box shell 1 in a sealing mode through pouring silica gel.
Furthermore, a continuous V-shaped aluminum foil 5 is arranged between every two layers of the S-shaped activated carbon fiber felt 2 to be embedded to form the partition plate.
Wherein, the size of the stainless steel box shell 1 is 610 multiplied by 762 multiplied by 160mm, the area of the air inlet 3 is not less than 250cm2The inner side of the air inlet is provided with a wind shield 8 which can reduce the wind speed and ensure that the nuclear air smoothly enters the active carbonIn a cavity 9 enclosed by the fiber felt 2 and the stainless steel box shell 1, the activated carbon fiber felt is convenient to uniformly disperse and comprehensively purify the nuclear air.
The stainless steel box shell 1 is formed by bending a stainless steel plate, a metal protective net is adhered to the outer side of the activated carbon fiber felt 2 after adhesion forming, and the activated carbon fiber felt 2 extends towards the wide surface of the stainless steel shell 1.
The novel material iodine adsorber is consistent with the current standardized II-type iodine adsorber in installation size, namely the sizes of the panel and the box body shell are kept, but the structure and the used filtering material are completely different. Firstly, the air inlet 4 is changed into an integral air inlet, and the area of the integral air inlet is not less than that of the air inlet of the original II-type iodine adsorber; secondly, the stainless steel box shell 1 is formed by bending a stainless steel plate into a concave three-side metal plate, and is integrally formed without welding; thirdly, after entering from the air inlet 4, airflow flows out from the wide surface of the stainless steel shell 1 through the activated carbon fiber felt 2 and the air outlet 3, and the airflow of the iodine adsorber is changed from the original air inlet at the middle part and the air outlet at the two sides to the air inlet at one side and the air outlet at the other side; fourthly, the filtering area of the iodine adsorber is 0.8m of the prior activated carbon particles2Increased to 2-3m of the activated carbon fiber2(ii) a Fifth, the weight of the iodine adsorber is only 1/4 of the current activated carbon particle iodine adsorber.
