Detailed description of the invention
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by detailed description of the invention.
As shown in Figure 1, it is a kind of organic exhaust gas secondary absorption retracting device that the specific embodiment of the invention proposes, comprise absorption casing 1, described absorption casing 1 comprises upper box and lower box, between described upper box and lower box, separate by dividing plate 2, shape, the size of the inwall of shape, size and the described absorption casing 1 of described dividing plate 2 are suitable.Wherein, described upper box inside is provided with adsorption layer 3, and described lower box inside is provided with lower adsorption layer 4.
Described upper adsorption layer 3 and lower adsorption layer 4 include respectively absorbent core 12, described upper adsorption layer 3 and lower adsorption layer 4 inside are respectively arranged with 1-10 absorbent core 12, and described upper adsorption layer 3 is identical with the quantity of the absorbent core 12 in described lower adsorption layer 4, and the quantity of the absorbent core 12 between the upper adsorption layer 3 in the present embodiment and lower adsorption layer 4 is respectively 4.As one preferred embodiment, described absorbent core 12 is carbon fiber adsorption and catalytic combustion core.The present embodiment arranges upper and lower two-layer adsorption layer in an absorption casing, the secondary absorption retracting device in existing equipment is integrated in an adsorbent equipment to floor space and the scale of in ensureing adsorption effect, greatly having reduced absorbing recovery device.
The center of described dividing plate 2 offered wind passage, the described wind passage of crossing is used for being communicated with described upper adsorption layer 3 and lower adsorption layer 4, the described wind passage of crossing can make organic exhaust gas pass through between described lower adsorption layer 4 and upper adsorption layer 3, because the size of mistake wind passage is little, so must being all full of the space of described lower adsorption layer 4, organic exhaust gas can enter into upper adsorption layer 3 by crossing wind passage afterwards, the setting of dividing plate 2 can make organic exhaust gas in upper and lower adsorption layer, be filtered fully absorption respectively, makes adsorption effect better.
The lower end of described absorbent core 12 is fixed on described dividing plate 2, and the upper end of described absorbent core 12 is fixed on described absorption casing 1; The inside of described absorbent core 12 offers the endoporus passing through for organic exhaust gas, and described endoporus extends to the lower end of described absorbent core 12.The size of described absorbent core 12 endoporus and described the measure-alike of wind passage of crossing.In the time that described absorbent core 12 is just arranged on the described above and below of crossing wind passage in installation process, if the inside of absorbent core 12 does not offer the endoporus passing through for organic exhaust gas, absorbent core 12, by stopping from described in adsorption layer 4 to the organic exhaust gas entering in described upper adsorption layer 3, will affect the recovering effect of device to organic exhaust gas so.Therefore absorbent core 12 inside offer one with the described measure-alike endoporus of crossing wind passage, can make retracting device more efficiently organic exhaust gas be reclaimed.
