Abstract

The present invention relates to a cigarette harmful component filtering liquor for effectively filtering harmful components of tar, nicotine and solid granular substances. Its main composition includes alum [KAL(SO4)2.12H2O], whose concentration is 3-5% (g/ml), acetic acid (C4H10C) whose concentration is 3-4% (ml/ml), alcohol (CH3-CH2-OH) whose concentration is 5-7% (ml/ml) whose concentration is 5-7% (ml/ml) and the rest is water. Said cigarette harmful component filtering liquor does not affect the taste of cigarette.

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 ₄H ₁₀O), 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 kind of compound method of 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 are formed.

2, the compound method of cigarette oxious component filtered fluid according to claim 1 is characterized in that alum (KAL (SO ₄) 2.12H ₂O), acetic acid (C ₄H ₁₀O), the mass fraction of ethanol (CH3-CH2-OH) is as follows respectively: alum: 3-5% (g/ml), acetic acid: 3-4% (ml/ml), alcohol: 5-7% (ml/ml), all the other are water.
