Description
Technical field
The invention belongs to tobacco plug manufacturing technology fields, and in particular to a kind of filtering based on polymer multicore fibre pipe
Device and its application.
Background technique
In recent years, electronic cigarette, heating do not burn the new tobacco productses such as tobacco product just in rapid rising.Electronic cigarette is not
The tobacco of pipe tobacco form is directly used, mainly will be atomized to form vaporous object from the nicotine liquid of tobacco.It heats non-ignitable
Burning tobacco product is to heat tobacco using external heat source rather than light tobacco to generate with tobacco flavor gas, has charcoal to add
The modes such as heat, electric heating.Novel tobacco is known as a healthier substitute of traditional tobacco product, the nuisance in flue gas
Matter is relatively fewer.But since novel tobacco is by the way of airtight heating, and cigarette is shorter, leads to entrance flue gas temperature mistake
It scalds, still has larger gap with traditional cigarette in terms of suction experience is with suction.Therefore, suitable cooling material is chosen
Have great importance to reducing flue-gas temperature, improving flue gas mouthfeel.
Patent 201210336384, which discloses one kind, can reduce filter rod of flue-gas temperature and preparation method thereof, in package material
Micropore aluminium layer is adhered to by glue-line in material front, reduces flue-gas temperature using the condensation of micropore aluminium, but the invention is only used for
Traditional tobacco, novel tobacco effect higher for exit gas temperature are unknown.
Patent 201710785910.9 discloses a kind of perfuming temperature-lowering base rod, and a certain proportion of diameter is adulterated in filter stick and is
The acid fiber by polylactic particle or acetate fiber particle of 0.45~0.6mm.Patent 201710785572.9 discloses a kind of cooling increasing
Fragrant film gathers base rod, and zigzag and the folding with the irregular exhaust gases passes of several size and shapes are wrapped up in filter stick
Shape acid fiber by polylactic film or acetate film.Whether granular materials or thin-film material, common problem are that accumulation is close
Spend smaller, material and smoke contacts limited area, it is difficult to realize the effect to flue gas fast cooling.
Summary of the invention
The technical problem to be solved by the present invention is to overcome deficiency in the prior art, provide a kind of based on polymer multicore

Inventive principle：
Multicore fibre pipe structure not only greatly improves filter and exchanges specific surface with smoke contacts, but also its is elongated
Play the role of throttling cooling in duct.In the present invention, multicore fibre pipe plays a part of similar porous plug, and high-temperature flue gas can only be from
Pass through in densely covered elongated orifice inside multicore fibre pipe.Since channel is shunk rapidly, flow of flue gas is hindered, and pressure is gradually
Become smaller, temperature also declines therewith.In general, duct is thinner, length is longer, and restriction effect is also more obvious, but correspondingly
Meeting is so that flow of flue gas is unsmooth.So the size of adjustment multicore fibre pipe internal gutter is a big key of the invention.

Much higher than general polymerization object material, there is very wide absorption heat but indeformable temperature model near human body comfortable taste temperature
It encloses, can largely absorb the incidental heat of high-temperature flue gas.
Compared with prior art, the beneficial effects of the invention are as follows：
1, multicore fibre pipe bulk material sensible heat value with higher, glass transition temperature are lower than 200 DEG C less than 50 DEG C, fusing point
And specific heat capacity is greater than 1.5kJkg-1·K-1, there is very wide absorption heat but indeformable near human body comfortable taste temperature
Temperature range, can largely absorb the incidental heat of high-temperature flue gas.
2, multicore fibre pipe structure greatly improves filter and exchanges specific surface with smoke contacts, to promote heat exchange
Rate quickly reduces the transient temperature of high-temperature flue gas.
3, squeezed out using continuous fusion, gradually it is cooling, stretch, thermal finalization handles and cuts out once-forming method and prepares multicore fibre
Dimension pipe is, it can be achieved that full-automatic production.
