Abstract

The present invention relates to a cigarette harmful-component filtering liquid which is mainly applied to a traditional Chinese water smoking set. The filtering liquid is capable of effectively filtering harmful ingredients such as tar, nicotine and solid particulates in tobacco smoke, and the harm to smokers by the cigarette is reduced. Furthermore, the present invention has no toxin or taste, and the mouth feel of the cigarette is not affected. The principal raw materials of the harmful ingredients of the cigarette for filtering are alum <KAL<SO4><2>12H2O>, acetic acid (C4H10O), and alcohol (CH3-CH2-OH), and the rest is water. The alum concentration is 3 to 5 percent (g/ml), the concentration of the acetic acid is 3 to 4 percent (ml/ml), and the alcohol concentration is 5 to 7 percent (ml/ml). The alum has the function as a flocculating agent and is generated into black precipitates by reaction with the harmful ingredients in the tobacco smoke. The acetic acid makes the filtering liquid keep subacidity to enhance the flocculating effect. The alcohol is capable of enhancing the absorption of fat-soluble harmful substances in the tobacco smoke for the filtering liquid.

Description

Cigarette oxious component filtered fluid

The present invention relates to a kind of cigarette oxious component filtered fluid, be mainly used in the Chinese traditional water smoking set, this filtered fluid can effectively filter the main oxious component in the smoke from cigarette, reduce the harm of cigarette to the smoker, also can be used in the smog abatement apparatus that other is filtered fluid with water, strengthen filter effect, reduce of the pollution of harmful smog environment.

Reducing on the method for cigarette to smoker's harm at present, it mainly is the filter tip that relies on the cigarette, but the main oxious component tar (polycyclic aromatic hydrocarbon in the smoke from cigarette, strong carcinogenic substance) and nicotine (nicotine, strong toxicity) at high temperature become gaseous state, be easy to by common cigarette filter, and cigarette can produce some harmful small solid particles simultaneously in combustion process, common filter tip can not effectively stop, so the common cigarette filter tip is very limited to the oxious component filter effect in the smoke from cigarette, can only reach about 10%.

At cigarette to the harm of human body and common cigarette filter tip to the bad problem of oxious component filter effect in the smoke from cigarette, we have developed a kind of smoke from cigarette oxious component filtered fluid that is mainly used in the Water pipe, be characterized in the main oxious component good filtration effect in the smoke from cigarette, and nonpoisonous and tasteless, do not influence the mouthfeel of cigarette.

The primary raw material that this cigarette oxious component filters is alum (KAL (SO ₄) ₂.12H ₂O), acetic acid (C ₄H10O), ethanol (CH ₃-CH ₂-OH) and water.Alum is coagulating sedimentation agent commonly used in the life drinking water disinfection process, in this filtered fluid, alum mainly plays the flocculant effect, promptly when the filtered fluid in the smoke from cigarette process Water pipe, be dissolved in harmful substances such as alum in the filtered fluid and the tar in the smoke from cigarette, nicotine and react, generate the black flocculent deposit.Simultaneously, the harmful small solid particle in the smoke from cigarette also is filtered liquid and stops and precipitate.The effect of acetic acid is an Acidity of Aikalinity of regulating filtered fluid, makes filtered fluid keep faintly acid, and liposoluble substances such as tar, nicotine flocculating effect under acid condition is best, and we find that through experiment repeatedly filter effect is ideal when the pH value of filtered fluid is 3-4.The main effect of alcohol is to strengthen the absorption of filtered fluid to fat-soluble harmful substance in the smoke from cigarette, strengthens assimilation effect.The mass fraction of various raw materials is as follows in the cigarette oxious component filtered fluid for preparing: alum: 3-5% (g/ml), and acetic acid: 3-4% (ml/ml), absolute alcohol: 5-7% (ml/ml), all the other are water.

Show that through our repetition test this cigarette oxious component filtered fluid is obvious to the main oxious component filter effect of at present commercially available cigarette, its filterability (filtering the preceding concentration of back concentration/filtration) is as follows:

Main this filtered fluid of oxious component filter tip light water (in the Water pipe) (in the Water pipe)

Tar 13% 18% 37%

Nicotine 8% 19% 27%

Particulate solid 17% 32% 33%

The compound method of this cigarette oxious component filtered fluid is as follows: (is example to prepare 500 milliliters of these filtered fluids)

1, takes by weighing alum 25 grams, pulverize, add about 350 milliliters in water, fully stir, alum is dissolved fully;

2, measure 15 milliliters of acetic acid, add in the above solution, stir;

3, measure 25 milliliters of absolute alcohols, add in the above solution, stir;

4, above solution is added water to 500 milliliters, stir, promptly get this filtered fluid.

In sum, this prescription filtered fluid has good filtration effect, and is nonpoisonous and tasteless, with low cost, and the compound method characteristic of simple can reduce the harm of cigarette to smoker's health.About 150 milliliters of this filtered fluid of once packing in the Water pipe was inhaled 10 cigarettes by one day, and the filtered fluid in the Water pipe is answered about 2 days and changed once, to guarantee its filter effect.

Claims

1. a cigarette oxious component filtered fluid is characterized in that it is by alum (KAL (SO ₄) 2.12H ₂O), acetic acid (C ₄H ₁₀O), ethanol (CH3-CH2-OH) and water forms, the concentration of each composition is respectively: alum: 3-5% (g/ml), acetic acid: 3-4% (ml/ml), alcohol: 5-7% (ml/ml), all the other are water.
