Embodiment 1

[0025] Such as figure 1 , figure 2 As shown, the present invention provides an externally-buried surrounding tube column trapping nozzle rod, which is composed of a tow core rod 1 and an outer layer of forming paper 4, and four tubes are arranged on the circumference of the tow core rod The core group is wrapped by the forming paper 4 on the tow core rod, and each tube core group is composed of 12 longitudinal tube cores 2 arranged along the circumference of the tow core rod.

[0026] Such as image 3 As shown, the surface of each longitudinal tube core 2 is provided with a set of drainage small holes 3, both ends of the longitudinal tube core 2 are respectively provided with end caps 2b, and a set of small holes 2c are also provided on the end cap 2b. The small aperture is 0.01-1.0MM.

[0027] The longitudinal tube core compresses the tow core rod toward the center to increase the center density, forcing part of the flue gas to flow through the small hole into the longitudinal tu...

Embodiment 2

[0029] image 3 The vertical tube core 2 in the middle can be a solid cylinder 2a made of activated carbon or nanomaterials with high air permeability and high adsorption. The cylinder has micropores 3a that can adsorb flue gas, such as activated carbon, sepiolite, Sponge, etc., can also achieve the purpose of intercepting smoke.

Abstract

The invention provides an externally buried tubular column surrounding type intercepting filter rod, which consists of a tow core rod (1) and wrap paper (4) coated on the outer layer. The outer circumference of the tow core rod is provided with vertically distributed pipe cores (2); the wrap paper (4) coats the pipe cores (2) onto the tow core rod (1); and the pipe cores (2) are provided with small guide holes (3). The externally buried tubular column surrounding type intercepting filter rod has the advantages that: the pipe cores vertically buried into the tow of the filter rod extrude local tow to make the density increase and force partial smoke diffuse to the pipe cores through the small holes on the pipe cores; when the smoke flows through the small holes, the smoke can be amplified by the small holes to be diffused in a fan shape, and the flow rate is reduced or the smoke is condensed; and the pipe cores are similar to 'cold wells', the flow rate of the smoke flowing through the pipe cores is reduced due to small pressure, partial smoke is condensed and deposited in the pipe cores, and the rest smoke flows into the tow through the small holes when flowing to the tails of the pipe cores.

Description

Technical field [0001] The present invention relates to tobacco products, in particular to a filter fiber-type tip of cigarette. Background technique [0002] The mechanism of the fiber nozzle to remove particulate matter in the flue gas is mechanical filtration. Its filtration efficiency is related to the size (mass and diameter) of the particles in the flue gas, the movement speed of the particles, and the degree of diffusion of the particles in the fiber filaments (distribution and distribution). Residence time) related. Because the time for the particles to pass through the nozzle rod is very short (0.04 seconds), the diameter of the particles is small (0.2 microns), while the diameter of the filaments (20 microns) is 100 times larger than the diameter of the particles. Therefore, the mechanical filtration (retention) rate caused by the fibers of the nozzle rod to the particles is small. [0003] The mechanical filtration of the fiber-type nozzle rod is to make the particles ...
