Abstract
The invention provides a spiral surrounding groove trapping filter rod consisting of a wire beam core rod (5) and molding paper (4) coated on an outer layer. A layer of inner layer paper (1) for coating the wire beam core rod is arranged between the wire beam core rod and the molding paper; at least one spiral groove (2) which surrounds the wire beam core rod is formed on the inner layer paper (1); and small guiding holes (3) are densely distributed on two side surfaces of the spiral groove. The spiral groove makes a groove longer in the axial direction of the wire beam core rod, so that the flue gas trapping efficiency is further improved; and the spiral groove is sunk in the wire beam to compress the wire beam core rod, so that the central density is improved so as to force partial flue gas to enter a lower-suction resistance spiral groove through the small guiding holes. Because the spiral surrounding groove prolongs the flue gas path, and the flue gas is subjected to actions of diffusion deposition, intensive flow, amplification of small guiding holes and other tar reducing mechanisms, the comprehensive effect of a fiber filter of reducing the tar and the harm is achieved to the greatest degree.
Description
Technical field
The present invention relates to tobacco product, particularly a kind of filter fibrous type mouth rod of cigarette.
Background technology
The mechanism that fibrous type mouth rod is removed particle matter in the flue gas is exactly that mechanicalness is filtered, and its filter efficiency is relevant with size (quality and diameter), the movement velocity of particulate, the diffusion (distribution situation and the time of staying) of particulate in filament of particulate in the flue gas.Because particulate passes through the time very short (0.04 second) of mouth rod, the diameter of particulate very little (0.2 micron), and filametntary diameter (20 microns) is bigger 100 times than the diameter of particulate.Therefore, the fiber of mouth rod mechanical filter (holding back) rate that particulate is caused is very little.
Fibrous type mouth rod mechanicalness filter be exactly make particulate in flow path constantly and fiber bump the formation inertia impact.Because the quality of the movement velocity of particulate and particulate is all little, the momentum that motion produces just can not be big, and therefore, inertia impact is to the contribution of cigarette filter tip efficient also very little (account for total clearance 2%).
The disordered motion of particulate causes that the collision with fiber promptly forms the diffusion deposition.Studies show that the motion of low quality particulate is more more than high-quality person, the mistakes rate effect that when low flow velocity, causes because of diffusion just generally, this has been the time lengthening that stops in filter tip owing to particulate, makes particulate have more opportunity and spreads in filament.The particle removal that is caused by the diffusion deposition accounts for 65% of total clearance.
When particulate very closely flows through fiber and collides with it direct interception function will take place, this mechanism is relevant with the size of particulate, and irrelevant with the flow velocity of particulate.This particulate of being removed by direct interception function accounts for the 30%-35% of total clearance greatly.
At present, cigarette props up generally to adopt and installs fibrous type mouth rod additional and alleviate the harm of smoking to human body, and the tow in the conventional fibre type mouth rod generally all is that straight bundle distributes, owing to added glue and the influence that rolls the process mechanism characteristic, it is uneven that the resistance to suction of filter tip distributes, and generally is that the center is little, big on every side.Therefore, flue gas mostly flows along the center of filter tip in filter tip fast, seldom to around diffusion, the mechanicalness filtering effect of tow occurs in the central area of filter tip substantially, the mechanicalness filter efficiency of tow is because of the smoke distribution inequality, and has a greatly reduced quality.Hold back efficient to satisfy the requirement of people for what improve fibrous type mouth rod, satisfy people again to the smoking demand simultaneously, must change original filter fibrous type mouth bar structure, reduce harmful ingredients in flue gas better and reduce tar content to reach to health.
Summary of the invention
Purpose of the present invention is exactly to hold back the not high defective of efficient for what overcome that existing fiber mouth rod exists, fiber mouth rod is carried out architecture advances, to improve the hold back efficient of fibrous type mouth rod to flue gas.
To achieve these goals, the present invention has adopted following technical proposals:
A kind of spiral surrounding groove trapping filter rod, it is made up of the forming paper of stranded core rod and outer parcel, it is characterized in that being provided with between stranded core rod and the forming paper internal layer paper of one deck parcel stranded core rod, internal layer paper is provided with at least one spiral grooves around stranded core rod, is laid with one group of intensive drainage aperture on the two sides of spiral grooves respectively.
The quantity of described spiral grooves can be selected between the 1-20 road, and concrete parameter can design according to falling burnt the requirement.The quantity of drainage aperture can be provided with 1-200 on every again centimetre length.
After the internal layer paper bag is wrapped up in stranded core rod, promptly formed the spiral grooves suitable mutually on the stranded core rod with internal layer paper.Internal layer paper is tobacco business fiber filter paper commonly used, also can be the cigarette paper of other type, and the spiral grooves vertical sectional shape can be V-arrangement, rectangle, trapezoidal, semicircle and other shape.They carry out equidistantly or not equidistant arrangement.
Internal layer paper enters opium pipe synchronously with outer paper after being pressed into required groove by indent mechanism, stranded core rod is rolled into filter fibrous type mouth rod, because the effect of plasticizer triacetyl glycerine is arranged in the stranded core rod, make tow by the moulding of internal layer paper shape, form concaveconvex structure between stranded core rod and internal layer paper and the outer paper simultaneously, drainage small aperture on its groove two sides is 0.01-1.0MM, flue gas enters groove through the drainage aperture, in the less groove of resistance, flow then around filter tip is peripheral, flow to the end, flow into the filter fiber from the drainage aperture again.Granule phase substance in the flue gas, when flowing out the drainage aperture, a fluid stream had both been produced condensation by fan-shaped amplification under hydrokinetic effect, and the flue gas aerosol particle is increased, and the speed that the flue gas particle of increase flows in groove also slows down thereupon.When flue gas enters the drainage aperture again, there are many flue gases can not enter the drainage aperture again because of particle increases, can enter that flue gas that the drainage aperture flows out is also easier to be held back by tow.With yew paper excellent the propping up with cigarette of above-mentioned fibrous type mouth sticked to one, efficiently hold back cigarette comprehensively thereby form unitary whole.
The invention has the advantages that:
1, spiral grooves structure, significant prolongation flue gas flow through the path and the time of filter tip.The efficient that makes filter tip hold back flue gas further improves;
2, the application of drainage aperture amplification principle has been created a brand-new fibrous type filter tip and has been fallen burnt mechanism, falls burnt machine-processed use in conjunction with " diffusion deposition " and " intensive flowing " two, can improve the burnt efficient of falling of fibrous type filter tip to greatest extent.The application of fluid dynamic " drainage aperture amplification principle " (air-flow is fan-shaped amplification when flowing out the drainage aperture) in filter tip, effectively little, the high volatility of the molecular weight in the cooled flue gas granule phase substance, harmful component cpd.Therefore present technique has tangible reducing poison function again.
Groove is like " cold well " (groove and the filter tip center temperature difference are very big), and the flue gas granule phase substance that flows through groove can be deposited by " cold well " condensation.Reduced and flowed into the maximum exhaust gas volumn of fiber again.Therefore groove also can be referred to as the new burnt mechanism of falling---" burnt mechanism falls in cold well ".
Therefore, patent of the present invention develops and has innovated the lowering harm and decreasing coking mechanism of fibrous type filter tip.
3, by all kinds of resistance to suction pressure reduction zone is set in filter tip, burnt mechanism falls in the laying of science " diffusion deposition " and " intensive flowing ", utilize " drainage aperture " to be connected in series each resistance to suction pressure reduction zone cleverly, the guiding flue gas flows by design path, allows unordered flue gas accept to fall the effect of burnt mechanism in an orderly manner, repeatedly.The flow process of flue gas is extended simultaneously, and the time of flowing through filter tip is delayed, and realizes diffusion, the distribution of the fullest of flue gas in filter tip.
4, road number, the depth, the width of spiral grooves,, the number of the size of drainage small aperture, drainage aperture, the distribution situation of drainage aperture etc. become the design considerations of fibrous type filter tip lowering harm and decreasing coking efficient.Use multifactor optimal design means, can be organically, the technical characteristic and the parameter of the design filter tip of science, thus satisfy the desirability of kinds of cigarettes to greatest extent, more efficiently to lowering harm and decreasing coking.
5, " the drainage aperture " on the internal layer forming paper can " off-line ", also can adopt online mode of adopting laser, static or mechanical punching to make.
For the present invention is described in further detail, following accompanying drawing provides a most preferred embodiment.
