The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The tobacco destructive distillation device with enhancing heat exchange as shown in Fig. 1～4, comprise that tubular heat conducting sleeve 1, cross section are criss-cross hollow inlet channel 2, described cross section is that criss-cross hollow inlet channel 2 is communicated with the internal cavity of tubular heat conducting sleeve 1, described cross section is that the appearance surface cover of criss-cross hollow inlet channel 2 has fuel slug 3, described cross section is that the shape of criss-cross hollow inlet channel 2 and the shape of fuel slug 3 match, and described cross section is the outer surface of criss-cross hollow inlet channel 2 and the laminating of the inner surface of fuel slug 3.Above-mentioned cross section is that criss-cross hollow inlet channel 2 can increase heat exchange area, can better heat like this air of flowing through, and has guaranteed the destructive distillation effect of tobacco.
In technique scheme, described cross section is to be provided with heat build-up chamber between criss-cross hollow inlet channel 2 and tubular heat conducting sleeve 1, and the outer surface in described heat build-up chamber also overlaps the fuel slug 3 matching with heat build-up cavity shape.
In technique scheme, described heat build-up chamber is infundibulate heat build-up chamber 7, and one end of described tubular heat conducting sleeve 1 is communicated with the large port in infundibulate heat build-up chamber 7, and the portlet in described infundibulate heat build-up chamber 7 is that criss-cross hollow inlet channel 2 is communicated with cross section.The other end of tubular heat conducting sleeve 1 is used for inserting cigarette 6.
In technique scheme, because heat build-up chamber is infundibulate heat build-up chamber 7, so the fuel slug 3 matching with heat build-up cavity shape is also infundibulate, above-mentioned like this fuel slug 3 has thinner part, is more conducive to igniting of fuel, guarantees that fuel slug 3 can completing combustions.Above-mentioned fuel slug 3 is carbonaceous fuel.
In technique scheme, in described tubular heat conducting sleeve 1 internal cavity, be provided with cigarette limiting plate 4, tubular heat conducting sleeve 1 internal cavity is divided into spacer region 1.1He Chayan district 1.2 by described cigarette limiting plate 4, described cigarette limiting plate 4 is provided with through hole 4.1, spacer region 1.1He Chayan district 1.2 is communicated with by through hole 4.1, and described spacer region 1.1 is between heat build-up Qiang Yuchayan district 1.2.Above-mentioned spacer region 1.1 causes cigarette burning for the fuel that prevents burning by metal, and suitable interval can prevent burning, makes the better destructive distillation of cigarette.Above-mentioned through hole 4.1 is a macropore coaxial with tubular airflow duct 2, or is several apertures as shown in Figure 3.Above-mentioned infundibulate heat build-up chamber 7 can make hot-air assemble at this, this infundibulate heat build-up chamber 7 coordinates with spacer region 1.1 can be sucking the air temperature control in Cha Yan district a rational scope, can avoid the high temperature tobacco component that ignites can avoid again air amount heating not.Guarantee the destructive distillation effect of cigarette.
In technique scheme, heat build-up chamber also can be circular cylindrical cavity.
Above-mentioned cigarette limiting plate 4 has limited the degree of depth that cigarette 6 inserts, and makes cigarette 6 and front end infundibulate heat build-up chamber 7 leave suitable space, has effectively avoided the high temperature tobacco component that ignites.Meanwhile, due to infundibulate heat build-up chamber 7 after fuel ignites by scorching hot fuel ring around, temperature can be higher than spacer region 1.1, can avoid like this air heat that sucks inadequate, and reduce destructive distillation effect.
In technique scheme, described Cha Yan district 1.2 outer cover have collet 5.
In technique scheme, the internal cavity diameter of described tubular heat conducting sleeve 1 and the external diameter of cigarette 6 match.
In technique scheme, described tubular heat conducting sleeve 1 is metal tub heat conducting sleeve, cross section is that criss-cross hollow inlet channel 2 is metal inlet channel, and infundibulate heat build-up chamber 7 is metal infundibulate heat build-up chamber, and the wall thickness of described metal tub heat conducting sleeve is 0.02～0.3mm.Metal tub heat conducting sleeve is too thin may be burned, and too thick destructive distillation effect is bad, and applicant draws above-mentioned wall thickness dimension scope by test of many times.
In technique scheme, the axial length of described spacer region 1.1 is 1～6mm.In the time that the axial length of spacer region 1.1 is less than 1mm, substantially do not have the effect that prevents burning, while being greater than 6mm, destructive distillation effect is bad.
In technique scheme, described tubular heat conducting sleeve 1, cross section are that criss-cross hollow inlet channel 2 and infundibulate heat build-up chamber 7 are coaxially arranged.
When the utility model uses, after fuel slug 3 is lighted, the metallic walls that is criss-cross hollow inlet channel 2 and infundibulate heat build-up chamber 7 by cross section is the air heat in criss-cross hollow inlet channel 2 and infundibulate heat build-up chamber 7 by the cross section of flowing through, air accumulation after heating is in infundibulate heat build-up chamber 7, then successively by the through hole 4.1 of spacer region 1.1, cigarette limiting plate 4, enter Cha Yan district 1.2, the interior hot-air in Cha Yan district 1.2 carries out destructive distillation processing to the tobacco of cigarette 6, has so significantly reduced the harmful components in flue gas.Cross section is that criss-cross hollow inlet channel can increase heat exchange area, can better heat like this air of flowing through, and guarantees the destructive distillation effect of tobacco.Temperature in infundibulate heat build-up chamber 7 is higher than interstitial area 1.1, can avoid like this air heat of suction inadequate, and reduce destructive distillation effect, funnel hole 3.2 parts of simultaneously corresponding fuel slug 3 are thinner, be more conducive to igniting of this part of fuel, guarantee that fuel slug 3 can completing combustion.
The content that this description is not described in detail belongs to the known prior art of professional and technical personnel in the field.
