Embodiment
[0024] Example. An air filter absorber
[0025] figure 1 , figure 2 The structure of the air filter absorber of this embodiment is shown in front view and top view respectively.
[0026] The filter absorber has a cylindrical structure, and from outside to inside there are filter absorber shell 4, filter absorber outer orifice plate 7, outer wire mesh 8, inner wire mesh 11, filter absorber inner hole plate 12, paper filter outer Orifice plate 13, orifice plate 16 in paper filter. The inner and outer orifice plates of the filter absorber are made of 1.5mm thick stainless steel plate rolled round, and the inner and outer wire meshes are spot-welded. There is an activated carbon adsorption layer 9 between the inner and outer wire meshes, and the filler is impregnated activated carbon (the activated carbon particles are columnar, with a particle size of 0.7-1.0mm , the strength is greater than 90%, and the packing density is greater than 0.4g / cm 3 , the benzene adsorption rate...

Abstract
The invention relates to an air filtering absorber. The air filtering absorber is of a cylindrical combined type structure, and is mainly composed of a filtering absorber housing, a paper filer, and an active carbon adsorption layer; the filtering absorber housing is composed of an internal pore plate, an external pore plate, an internal screen net, an external screen net, a pressing pad, and a sealing plate; the paper filter is composed of a primary efficiency filtering layer, a high efficiency filtering layer, and a paper filter internal pore plate. The air filtering absorber adopts the cylindrical combined type structure, resistance is low, adsorption area is large, multi-stage adsorption is realized, purifying capturing efficiency is high, high efficiency filtering material impregnated activated carbon is adopted, the air filtering absorber is invented based on pure physical principles, no energy consumption is caused, maintenance is simple and convenient. The air filtering absorber is suitable to be used in sealed spaces such as sealed defense works, vehicles, ships, and shelters, can be used for filtering radioactive ash, chemical toxins, and biological toxins, and purifying rate is increased to be 99.999% at a nominal air delivery.
Description
technical field [0001] The invention relates to an air filter device, in particular to a filter absorber which is the core component in the filter adsorption device. Background technique [0002] The function of the filter absorber is to filter out the pollutants in the air to protect personnel and equipment from pollution. The so-called air pollutants include nuclear radioactive dust, chemical poisons and biological poisons. Obviously, the adsorption efficiency of the filter absorber during the filter adsorption process is an important indicator of the anti-pollution effect. [0003] At present, the filter absorbers with large air volume on the market are mostly composed of filter paper boards and activated carbon boards, and have a rectangular parallelepiped structure. In use, the requirements for the filter absorber are: the volume should be small, easy to install and replace, and not only the filtration efficiency should be high, but also the service life should be lon...
