Abstract

The present invention filters toxic substances and tar substances existing in gas by using rhubarb powder or an efficient extractive thereof, particularly filters toxic substances in tobacco smoke, such as nicotine, tar, etc., so that the smoke becomes light and mellow, the harm of smoking to smokers and the pollution to environment can be reduced, and the present invention is helpful for smokers who wants to stop smoking to abstain the smoking habit. A tobacco smoke filter element prepared by the present invention can be directly used as a filter tip of a cigarette or arranged in a smoke passage of a tobacco pipe and a cigarette holder.

Description

High efficiency archen nicotine, tobacco tar filter tip

The invention belongs to absorption and be present in the noxious material in the gas, the physico-chemical process of tar class material and the preparation of filter stamen.The present invention finds that rheum officinale (comprising the active principle that extracts from rheum officinale) has the good adsorption effect to the tar class material that is present in the gas, and an amount of indigo naturalis of adding, cow-bezoar, borneol help the filtering of tar and other noxious material as auxiliary material in rheum officinale.

Filter course or filtration stamen can prepare with Rhubarb or its effective extract, or add the appropriate amount of auxiliary materials preparation, or combine preparation with other filter paper, filter cloth, filter stamen material.

The present invention is specially adapted to noxious materials such as cigarette alkali, tar in the filtering smoke of tobacco.Owing to harmfulness of smoking health, how to improve the efficient of noxious material in the filtering flue gas, producing " safe cigarette " is the important subject in the tobacco industry.Efficient and the cheap filter toxic smoke of preparation is chewed and not only can be reduced smoker's murder by poisoning itself and can reduce the pollution of flue gas to environment.

It is that example further specifies that the present invention will chew with the cigarette filter in the following example.

Example 1

As scheme shown in the A, the cigarette that routine is used filters stamen and is divided into two

section

1,3 sandwiches one deck 20～80 purpose Rhubarbs 2 at two sections in the middle of filtering stamens, the thickness of Rhubarb layer can by 0.2 millimeter with down to 2 millimeters, can be according to the actual requirement of cigarette alkali rejection rate is decided.Generally can adopt the Rhubarb filtering layer of 20～40 orders, 0.5～1 millimeters thick.

Example 2

With the rheum officinale decocting, the filtering residue is with the cigarette filter stamen that rheum officinale water-leach liquor dipping widely uses at present, oven dry then.

Example 3

Rhubarb is mixed loose fibrous material make the filter stamen.

Example 4

Rhubarb is modulated into pasty state, shown in figure B, Rhubarb layer 4 is filtered an end of the nearly cigarette 6 of stamen 5 with the method for coating or dipping attached to cigarette.

In above example, all can in rheum officinale, add an amount of indigo naturalis, cow-bezoar, borneol.

With the filter stamen of the inventive method preparation can be directly as the filter tip of cigarette 6, or make separately and have the disposable filter tip that cigarette inserts mouth, or place the exhaust gases passes of tobacco pipe, cigarette holder.

Adopt the present invention to filter the tobacco product of stamen, flue gas is simple and elegant pure and mild when sucking, the excitant of the no pungent larynx of choking.With the blend type cigarette in the tar content is example, adopts the filter stamen of example 1, cuts the filter stamen open after exhausting a cigarette, and can be observed: filter stamen 1 is rufous; Originally being that yellow Rhubarb layer 2 is changed to pitchy, is that the tar that loose Rhubarb is adsorbed thereon bonds agglomerating originally; Filter stamen 3 only is faint yellow at core.Obviously, the Rhubarb layer has been held back most cigarette alkali and tar.

Claims

1, absorption is present in the noxious material in the gas, the filter stamen of tar, it is characterized in that making the main material of filter stamen or a kind of material in the filter stamen composition with the effective extract of rheum officinale or rheum officinale.

2, according to the filter stamen of claim 1, be used for cigarette alkali, the tar of filtering smoke of tobacco, it is characterized in that, chew an end that is positioned at cigarette by its filter of making.
