Abstract

The present invention uses Rhubarb or its effective extract filtering to be present in noxious material and tar class material in the gas.Particularly noxious materials such as cigarette alkali, tar in the filtering smoke of tobacco make flue gas simple and elegant pure and mild, reduce smoking to smoker's harm with to the pollution of environment, and help the ES to give up craving for tobacco.With the tobacco smoke air filter stamen of the present invention preparation can be directly as the filter tip of cigarette or place the exhaust gases passes of tobacco pipe, cigarette holder.

Description

The efficient cigarette alkali of rheum officinale (nicotine), tar filter

The invention belongs to filtering 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 is specially adapted to noxious materials such as cigarette alkali, tar in the filtering smoke of tobacco.

The content of cigarette alkali generally accounts for 70～80% of cigarette alkali amount in the tobacco in the smoke of tobacco, and the filter tip that widely uses can filtering part noxious material at present.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 mouth of preparation not only can reduce the murder by poisoning to smoker itself, and can reduce the pollution of flue gas to environment.

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.This specification stresses the method for using noxious materials such as cigarette alkali, tar in these medicine filtering smoke of tobacco and the preparation of filtering stamen.

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 will be illustrated more clearly in the following example.

Example 1

As scheme shown in the A, the cigarette filtration stamen that routine is used is divided into two section 1,3, sandwich 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. Blend type cigarette in the tar content adopts the filter stamen of example 1 as example, 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
