Embodiment
Embodiment 1
The 8kg rice husk, after the removal of impurity, is put into to carbonizing chamber 1, cover slip bell 2.Connect circular electrical heating tube 3, switch on 7 minutes, open the air compressor be connected with intake valve 17, make pressure reach 170 pounds/square inchs of gauge pressures, temperature, at 95 ℃, continues 25 minutes, removes the moisture in rice husk.Close air compressor, close intake valve 17, open vent valve 18, pressure is controlled under 170 pounds/square inchs of gauge pressures, persistently overheating to 200 ℃, keep 35 minutes.After 9 to 830 ℃ of the interior temperature of continuation adjusting carbonizing chamber 1.Close the vent valve 18 on carbonizing chamber, make rice husk carry out the pyrolysis carbonization in the sealing anaerobic environment, continue 45 minutes.Detaching active fire fire grate 10, make the high temperature cabonization rice husk slide into cylinder 4 along inner wall smooth steel pipe 3, is that 25 rev/mins of cylinders rotate through speed, realizes coolingly fast, lasting after 55 minutes, from the cylinder mouth, collects.
Implementation result: through aforesaid method, drop into altogether rice husk material 8kg, the production time is 167 minutes, produce carbonization rice husk 1.5kg, productive rate is 19%, C content 63%, H content 2.4%, N content 1%, the rice husk carbonizing rate is 99.9%, yield rate is 99.7%, fusing point is 1830 ℃.
By slip bell 2, suitable rice husk is installed in carbonizing chamber to 1, carbonizing chamber 1 inner bottom part two ends adopt circular electrical heating tube 3, make the rice husk direct heating, thereby impel it to ignite.The insulating material 4 that the carbonizing chamber inwall adopts reduces the thermosteresis of carbonizing chamber inner arm 5 in burning and pyrolytic process.At first carbonizing chamber 1 is pressurized.Open the air compressor be connected with intake valve 17, air is delivered in carbonizing chamber 1 through air intake valve 17, by lifting carbonizing chamber 1 internal pressure, realizes required pressure.Then, energising makes the rice husk in circular electrical heating tube 13 heating carbonizing chambers 1, in heat-processed, can carry air-breathing to carbonizing chamber 1.Perhaps, can first heat the temperature of rice husk to burning-point, then add air, make carbonizing chamber 1 inside reach required pressure.Discharge gas by vent valve 18 from the carbonizing chamber upper right quarter, further control the pressure in carbonizing chamber 1.Carbonizing chamber 1 internal temperature can be monitored by thermopair 9.Carbonizing chamber 1 internal pressure can be monitored by pressure warning unit 12.Between the heating period before lighting, because rice husk contains moisture, easily vaporization, pressure can rise.When rice husk is lighted, the meeting that temperature and pressure rise is faster.Now, in circular electrical heating tube 3 energisings, within 5-8 minute, can close swap switch, so that the outer energizing quantity of carbonizing chamber 1 reduces to best.Discharge the carbonizing chamber internal gas by vent valve 18 when pressure warning unit 12 reaches the pressure prescribed limit, this specified limit generally is no more than 380 pounds/square inchs of gauge pressures.The optimum pressure scope control is 120-180 pounds/square inch of gauge pressure, to maintain burning.By every kilogram of dry rice husk, calculate, the total air that is delivered to carbonizing chamber 1 is no more than 1.7 kilograms.Carry the air required time to depend on air and material amount, in 60-90 minute.Gas in vent valve 18 and vapor pipe 16 release carbonizing chambers 1, to reduce the pressure in carbonizing chamber 1.After the abundant carbonization of rice husk in carbonizing chamber 1, through active fire fire grate 10, slide into cylinder 4 along inner wall smooth steel pipe 3, rotate through cylinder 4, realize coolingly fast, there is gear 41 at cylinder 4 two ends, gear 41 bottom positions have motor 42, motor 42 synchronously rotates, and speed is 25 rev/mins, and last cooled carbonization rice husk is collected.
In the above conditions, the accurate carbonization time of the rice husk in carbonizing chamber depends on and the moisture content of rice husk still, generally is no more than 122 minutes.
Obviously, the above embodiment of the present invention is only for example of the present invention clearly is described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give all embodiments exhaustive.Every still row in protection scope of the present invention of apparent variation that technical scheme of the present invention extends out or change that belong to.
