The invention increases the solid temperature from inner to outer, to accelerate the speed and heat uniformly, with short degas time that 10-15min from room temperature to 510Deg. C.
Description
Technical field
The present invention relates to a kind of low temperature distillation experiment device.
Background technology
At present, under lab electric furnace is adopted in the destructive distillation of coal sample, put into the coal sample in the aluminium rice steamer, the aluminium rice steamer is put into the electric furnace heating, heats up, and the temperature of coal sample can from outward appearance to inner essence progressively raise, problem is that programming rate is slow, is heated to desired 510 ℃ from room temperature, be with 65～70 minutes, continue constant temperature 20 minutes again, need 85～90 minutes altogether, because from the surface heating, so heat inhomogeneous, the destructive distillation effect is undesirable, and the oil content data error that is measured is big.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of low-temperature carbonization device using microwave is provided.
The present invention realizes by following scheme, and the coal sample is placed in the rice steamer body that quartz glass makes, and replaces electric furnace with micro-wave oven, realizes low temperature distillation.
A kind of low-temperature carbonization device using microwave comprises delivery line, blast pipe, conical flask, bosh, temperature measuring equipment, it is characterized in that, adopts micro-wave oven as heater, and the adopting quartz glass material is made rice steamer body, Zeng Gai; Adopt ceramic material to make rice steamer body, Zeng Gai; Can be provided with two above rice steamer bodies, Zeng Gai and supporting delivery line thereof, blast pipe, conical flask etc. in micro-wave oven, realize that flexibly more than 1,2,3,4 parallel sample carries out the destructive distillation experiment simultaneously, in the hope of test with the time short and experimental result more accurately.
The invention has the advantages that, micro-wave oven low temperature distillation heating, the temperature of solid sample is progressively raise by lining and table, sample is heated soon, homogeneous heating, the time weak point that destructive distillation is used is raised to 510 ℃ from room temperature and only needs 10～15 minutes, shorten the experiment required time greatly, and measured the oil content data accurately, reliably.
Description of drawings
Fig. 1 is that the present invention constitutes schematic diagram.
Micro-wave oven 1, rice steamer lid 2, rice steamer body 3, shelter-clad 4, delivery line 5, blast pipe 6, conical flask 7, bosh 8, infrared inductor 9, display list 10, binding post 11, adjusting knob 12, temperature sensor 13, bearing 14 are arranged among the figure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is made and to further describe.
As shown in Figure 1, micro-wave oven 1 has heat temperature raising and thermostatic control function, after sample is heated to 510 ℃, can reach 20 minutes at 510 ℃ by automatic constant-temperature, micro-wave oven 1 is provided with adjusting knob 12, in order to linear regulation microwave energy watt level, there is infrared inductor 9 to measure rice steamer body 3 shell temperatures, there is one in the display list 10 to show its data, detect the temperature of sample in the rice steamer body 3 with temperature sensor 13, through binding post 11, show its temperature data by in the display list 10 another again, temperature sensor 13 adopts thermistors---and resistive conductor constitutes, to prevent that strong microwave field from disturbing, destructive distillation goes out gas and goes into conical flask 7 through delivery line 5.Incondensable gas is discharged by blast pipe 6, delivery line 5 outsides are surrounded by the ribbon heater, heat, make its temperature be controlled at 100～120 ℃ during experiment,, cause that to measure data inaccurate in case oil product runs off in the condensation of gas gas, in the bosh 8 cooling water is housed, gas in order to cooling distillates for preventing microwave leakage, is provided with shelter-clad 4 in delivery line 5 exits.
Operating process is as follows:
The solid fuel sample is put into rice steamer body 3, cover rice steamer lid 2, compress, rice steamer body 3 is put into micro-wave oven 1, and temperature sensor 13 causes binding post 11, delivery line 5 is linked rice steamer body 3, another termination conical flask 7, conical flask 7 are put into 8 li of boshes, and bosh is equipped with mixture of ice and water for 8 li, notice that bottleneck should exceed the water surface, the connection power supply heats, destructive distillation.
Micro-wave oven 1 is placed with 1,2,3, more than 4 rice steamer body 3, rice steamer lid 4 and supporting delivery line 5 thereof, blast pipe 6, conical flask 7 etc., can realize that a plurality of parallel samples carry out the destructive distillation experiment simultaneously, under same test conditions, its result of the test has very strong contrast, data are accurate, also can save time greatly simultaneously, make a concentrated effort to finish the progress of experimental duties.
