Description

A kind of pyrolysis device

Technical field

The utility model relates to a kind of tobacco or other organism high temperature carbonization thermal cracker of being used for.

Background technology

Cigarette is because the flue gas that the consumer is produced by suction pipe tobacco burning obtains certain satisfies.Smoke components be cigarette shreds by burn, distillation, destructive distillation, pyrolysis and complicated process such as synthetic again form.Cigarette props up when being burnt and sucked, and its fragrance thing not only derives from the combustion zone that cigarette props up, and the more important thing is to derive from its destructive distillation pyrolysis zone.Therefore study thermal cracking, destructive distillation of tobacco and synthetic product again, can systematic analysis other important perfumery that causes except that the aroma substance that directly discharges by high temperature combustion zone, comprise surperficial volatile matter, pyrogen, complex etc. again, can further describe the combustion process that cigarette props up and the mechanism of the fragrant jealous formation of flue gas like this from another side.In these researchs, cracker is that gas chromatograph is done the important accessory that pyrolysis chromatography is analyzed.

Some can not get rid of the interference of oxygen in the empty institute fully existing cracker, makes the tobacco leaf generation aerobic reaction of a part like this.And existing cracker also easily produces secondary reaction, and protection gas is difficult to deficiencies such as uniform Control Flow.

The utility model content

The purpose of this utility model aims to provide the interference of oxygen in the deaeration effectively, makes tobacco leaf or the abundant cracking of other organism, helps shortening the cracking time, raises the efficiency and becomes cheap a kind of pyrolysis device

The purpose of this utility model realizes by following manner:

The utility model comprises the cracking quartz ampoule; cartridge heater; the cracking quartz ampoule place cartridge heater in; cracking quartz ampoule inlet end is established a band push-rod piston; also be provided with on the described cracking quartz ampoule and be respectively equipped with two interfaces; first interface is connected with the shield gas flow rate controller, and second interface then is connected with the vacuum cycle water pump.

Be provided with a piston switch between two interfaces, described second interface that is connected with the vacuum cycle water pump is positioned at the band push-rod piston on one side.

Described cartridge heater also is provided with temperature controller.

Advantage of the present utility model is, is connected with vacuum extractor owing to added interface, and the interference of oxygen in the deaeration well makes tobacco leaf that real cracking rather than aerobic reaction can take place; The argon gas of external digital display or nitrogen flow controller make the blanket gas flow velocity of cracking evenly accurate, have improved the repeatability of experiment; The cracking time short (getting final product in 1-2 minute), the efficient height, and the utility model can shorten and make the cracking material at cracking quartz ampoule outlet pathway, can reduce the generation of secondary reaction to greatest extent; Cracking utensil of the present invention also has simply and is easy to do characteristics with low cost.The utility model can also detect the cracking granule phase substance, simultaneously also in the back tape splicing have the multistage absorption plant of cold well to remove to detect whole lysates;

The utility model set piston switch between two interfaces can also play better insulating effect, helps the carrying out of cracking reaction.

Embodiment

Present embodiment is intended to illustrate the present invention rather than limitation of the invention further, and the present invention can implement by described any mode of summary of the invention.

Referring to Fig. 1; shown in Figure 2; present embodiment comprises cracking quartz ampoule 16; cartridge heater 4; cracking quartz ampoule 16 place cartridge heater 4 in, cracking quartz ampoule inlet end 3 establish one the band push rod 9 rubber piston 10, also be provided with on the described cracking quartz ampoule 16 and be respectively equipped with two interfaces; first interface 11 is connected with boundary belt valve digital display gas flow controller 2, and 12 second interfaces are connected with vacuum cycle water pump 6.

Be provided with a piston switch 13 between two interfaces, described second interface 12 that is connected with vacuum cycle water pump 6 is positioned at band push-rod piston 10 on one side.

Described cartridge heater 4 also is connected with temperature controller 5 can regulate temperature.Described temperature controller 5 is connected with temperature controller by the thermocouple induction point at cracking temperature check point 8 places, and temperature is regulated in induction.

Use of the present utility model is:

In advance the cracking quartz ampoule is inserted in the cartridge heater 4 that reaches design temperature steady temperature about 10 minutes;

1, the aluminium alms bowl 15 that the 60-80 order sample of weighing good (0.2-0.4g is advisable) will be housed is put into the inlet end 3 of cracking quartz ampoule, covers the rubber piston 2 that has push rod 1, and the state that piston switch 13 is screwed to out;

2, the proofed sleeve that will connect gas flow controller 2 is connected with first interface 11, and the pipe that connects vacuum pump 6 is connected with second interface 12; The impermeability that guarantees whole device will be got well;

3, second interface 12 that will connect vacuum pump is earlier turned off, and opens nitrogen or argon gas source of the gas, and preliminary filling protection gas connects the rubber cigarette holder 7 that has cambridge filter at endpiece after 5 minutes again in cracking quartz ampoule 16, continues inflation 3 minutes;

4, shut the outlet of rubber cigarette holder 7, turn off gas flow controller 2, open vacuum pump 6 and begin to vacuumize at once; keep air pressure in the cracking quartz ampoule at-0.1MPa; open gas flow controller 2 after 5 minutes immediately, and turn off vacuum pump 6, continued to fill again protection gas 5 minutes.
