Description

Lead wire internal combustion low temperature cigarette

technical field

The utility model relates to the technical field of smoking cigarettes, in particular to a low-temperature cigarette with internal combustion through a lead wire.

Background technique

The central combustion temperature of ordinary cigarettes is about 550-800°C. As we all know, thousands of harmful substances will be released when cigarettes burn, and as the temperature increases, the types of toxic substances released will also increase.

During the high-temperature combustion of cigarettes, both the original components are destroyed and new substances are formed. The main components of the smoke include: ① nitrosamines, pyridine, pyrrole and other substances produced by oxidation during the combustion of tobacco alkaloids; Carbon monoxide, carbon dioxide, hydrogen sulfide and simple amides generated by strong oxidation; ③ volatile aldehydes, ketones and other substances generated by oxidation of resins, polyphenols and glycerin. Among them, gas phase substances account for more than 90% of the total smoke, and the content of particulate matter is less than 10%, mainly tobacco alkaloids, tar and water. The other components are semi-volatile components. These semi-volatile components constitute the main components of smoke aroma and taste. They can remain volatile and partially decomposed at a certain temperature (100--200°C). State, this type of semi-volatile substances in an ordinary cigarette is composed of about 300 substances with a boiling point of 70--300°C.

In the process of smoking cigarettes, when the cigarette butt burns from left to right, the combustion temperature of tobacco changes non-linearly, and is usually divided into three regions: high-temperature combustion region, pyrolysis distillation region and low-temperature condensation region.

The oxygen in the high-temperature combustion zone is sufficient, and the tobacco burns fully. The temperature can be as high as 800°C and the length of the combustion zone is about 0.4-1.0mm. and water and other low-level hydrides;

Most of the heat released by the violent oxidation reaction in the high-temperature combustion zone is brought into the pyrolysis distillation zone by the flue gas. This is also the zone where the most chemical reactions occur during the cigarette combustion process. Volatile 5-membered and 6-membered nitrogen-heterocyclic compounds have a significant impact on the aroma of the flue gas. Due to the large number of endothermic reactions in the distillation zone, the temperature of the flue gas dropped rapidly from 800°C to about 100°C.

The most end area is called the condensation filter area, and the flue gas is lowered from 100°C to room temperature. After the low-volatile components are condensed, part of them adheres to the shredded tobacco, and the other part forms condensation nuclei in the form of tiny carbon particles, or combines with other organic matter and ash, or enters the human mouth with the main smoke.

It can be deduced that under the premise of ensuring the inhalation and taste of cigarette smoke, the key position to minimize the generation of harmful substances lies in the thermal distillation zone. At this time, the optimum temperature for cigarette burning should be controlled to be 100-300°C.

In addition, the combustion mode of conventional cigarettes will produce a large amount of soot, which is not only not conducive to environmental protection and hygiene, but also causes safety hazards such as fire.

Therefore, prior art needs to be improved.
