The modified cellulose of skeleton structure functional group can quickly produce endothermic reaction with flue gas, achieve the purpose that reduce flue-gas temperature,
The modified cellulose aerogels of functional group have pore structure simultaneously, which can not only increase cooling material airsetting
The contact area of glue and flue gas, realization respond rapidly to reduction flue-gas temperature, can also have while ensureing flue gas trafficability performance
Various harmful substances in effect retention flue gas.
By adjusting the proportion of the modified cellulose of starch, chitosan and functional group, freezing dry process can be regulated and controled
The amount of middle crystalline growth point, to control the quantity in the hole formed inside cooling material aeroge, wherein starch and chitosan
The ratio that amount accounts in three's mixture is bigger, and obtained cooling material aeroge mesoporous is fewer, and cooling material reduces flue gas
The effect of temperature is poorer, avoids and causes since the modified cellulose of a large amount of skeleton structure functional groups quickly absorbs flue gas heat
Flue-gas temperature it is too low.
Wherein, use carboxy functional group to cellulose modified method in step (1) are as follows: acetic acid is added in cellulose
Then the multicomponent oxide agent being made of sodium metaperiodate, sodium hypochlorite and sodium chlorite is added in buffer, wherein sodium metaperiodate, secondary
The mass ratio of sodium chlorate and sodium chlorite is 1:10:12, and cellulose and the mass ratio of multicomponent oxide agent are 1/2, are kept away at 30 DEG C
Light is stirred to react 20h, filters, washing, and product is assigned as the dispersion liquid that mass fraction is 0.2%, equal using microjet high pressure
Matter machine is handled 4 times, obtains the cellulose modified through carboxy functional group.
Wherein, the tube wall 21 of the cooling element is made of acetate silk.
Wherein, the flavoring section 3 is the polylactic acid reticular membrane gathered for being enclosed with perfumed gel.
Wherein, the fillter section 4 is acetate silk.
Wherein, the smoke core material section 1 is rodlike smoke cigarette made of the unordered filling of the reconstituted tobacco comprising fragrance matter
Core.
