Not the shortcomings that good adsorption capacity is not able to maintain under the conditions of profit.Activated carbon fibre has that large specific surface area, thermal capacity is small, absorption solution
The features such as speed is fast, energy consumption is low is inhaled, is a kind of more popular new adsorbent；Adsorption efficiency is very high, according to handled useless
The organic gas content of gas and the difference of other physical characteristics, for adsorption efficiency between 85% to 98%, multi-stage absorption technique can
To reach 99.99%, significantly larger than the highest adsorption rate 88% of active carbon particle absorption method, and volume and total weight are also all very
It is small；But since price is too high, it is difficult to handling high humility organic exhaust gas, using being restricted.
Existing adsorbent is mostly the solid of porous structure in absorption method, but due to solid absorption exhaust gas in impurity mistake
Cheng Zhong, always the outer surface of porosu solid adsorbent first touches exhaust gas, thus for entire adsorbent, when with using
Between extend, the adsorption capacity of outer layer is more and more weaker, also, outer layer, after adsorbing contaminant, outer layer aperture can gradually become smaller, and exist
The problem of exhaust gas enters absorbent interior channel is blocked, causes losing suction-operated or suction-operated variation in adsorbent
Afterwards, but cause adsorbent utilization rate very low, simultaneously for the adsorption efficiency of exhaust gas also with the ability of adsorbing contaminant inside
It is poor.

Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a kind of efficient suctions for organic exhaust gas
Attached dose and preparation method thereof, it can form three to exhaust gas by partly connecting ball and connecting ball and interior adsorbing sphere entirely from outside to inside
Layer absorption barrier, enables exhaust gas repeatedly to be adsorbed by this adsorbent, effectively improves the adsorption efficiency of this adsorbent and to useless
The treatment effect of impurity in gas, while with the extension of use time, the outer ball table that falls off on the outermost side partly connected on ball
The water-soluble adhesive tape stickiness in face declines, so that the adhesive force between ball and outer a chain of strut that falls off outside declines, under backblast, easily
It falls, that is, is located at the ball meeting nature that partly connects that outermost adsorption capacity is deteriorated and falls off, make internal two layers of absorption barrier exposure, have
Effect avoids the case where outer layer suction-operated is deteriorated due to influences whole adsorption efficiency after being used for a long time, and then improves entire inhale
