Abstract
The present invention relates to a kind of method and apparatus that utilizes straw crushed material system inflammable gas, its principal character is straw pulverizing back to be mixed with a certain proportion of subsidiary stir evenly, under the state of basic secluding air, heat 300～500 ℃, carry out cracking, building-up reactions, make inflammable gas.This method is simple, reliable, gets material easily, and cost is low, the cleaning gas that makes.This equipment mechanism is simple, processing ease.Being particularly suitable for rural town applies.
Description
The present invention relates to a kind of method and apparatus that utilizes the pure thing system inflammable gas of plant stalk powder.
The preparation method of existing civilian and industrial inflammable gas mainly is with coal generating gas.For some scarce coal area, particularly rural town, utilize the coal generating gas investment big, the cost height, the peasant does not afford to do.At present, the main source of countryside and peasantry domestic energy is the plant straw, but burning the time had both been wasted the energy, had polluted environment again.
The objective of the invention is to propose a kind of method and production unit that utilizes the plant straw to produce inflammable gas at above-mentioned weak point, the combustible gas gas that this method is produced is inexpensive, and health, can be widely used as people's domestic energy.
Technical solution of the present invention:
One, analysis of experiments:
1, to the heat test of the pure thing of plant stalk powder under the secluding air state.
Put into Reaktionsofen after the pure thing of plant stalk powder (as wood sawdust, straw chaff, wheat straw chaff etc.) dries and make it secluding air, be placed on and be heated on the stove fire more than 300 ℃, then carry out scission reaction in the Reaktionsofen, generate inflammable gas, the main chemical reactions formula:
As seen from the above equation, inflammable gas is carbon monoxide and methane, calculates by theoretical value, and the inflammable gas after the generation accounts for 88.9% of reaction-ure mixture.
2, the pure thing of plant stalk powder is added the heat test of assisted reaction thing under the secluding air state.
The assisted reaction thing is coal or sulphur, considers the economy of coal in the practical application and does not produce obnoxious flavour, selects coal proper as the assisted reaction thing, bituminous coal, hard coal all can, behind the abundant crushing screening of coal, according to the mince ratio of weight of plant stalk powder be 12%-16%, admix plant stalk powder and stir evenly in mincing, drop in the Reaktionsofen then, make it secluding air, be heated to more than 300 ℃, mixture carries out cracking, closes and separate reaction, generate inflammable gas, its main chemical reactions formula is:
As seen from the above equation, inflammable gas is carbon monoxide, propane and butane, by theoretical value, the inflammable gas of generation be reactant summation 89.7～100%.
3, plant stalk powder is minced to mix add coal dust the heat test of little air under getting the hang of arranged.
Plant stalk powder is minced and coal dust mixes according to the above ratio, put into Reaktionsofen after, have little air to enter, be heated to more than 300 ℃, mixture carries out cracking, building-up reactions generates inflammable gas, the main chemical reactions formula is:
As seen from the above equation, inflammable gas is carbon monoxide, propane.Calculate by theoretical value, the inflammable gas of generation accounts for 92.1% of reaction-ure mixture, brings air not include input amount, and the combustible gas of generation is 107% of an actual input amount.
In the suitability for industrialized production of reality, plant stalk powder minces with after coal dust mixes, though handle through mechanically-sealing apparatus, but still unavoidably bring little air in the Reaktionsofen into, actual chemical equation mainly is the comprehensive of (2), (3), (4) three phases, and the ratio that three reactions are respectively estimated one's own ability depends on the ratio that adds coal dust and bring air capacity into, and the actual inflammable gas that generates mainly is carbon monoxide, propane, butane.Record carbon monoxide about 70% by experiment, propane, butane account for 30%, calculate by theoretical value, the air capacity that removal is brought into, it is 89.7～107% that the inflammable gas that produces accounts for the variation range that drops into reaction volume, record by experiment again, plant stalk powder mince and coal dust in the comprehensive ratio of impurities be 40%, so actual produce inflammable gas to account for the ratio variation range that drops into the raw material total amount be 54～64%.
So technical solution of the present invention is:
After the plant straw fully pulverized, add certain subsidiary, reacting by heating under the state of basic secluding air, temperature of reaction is 300～500 ℃, the add-on of subsidiary is the 12-26% of the weight that minces of plant stalk powder.Reaction times is 2.5 minutes to 3 minutes, and the subsidiary of adding is sulphur or coal dust, preferably coal dust.
Using the equipment of aforesaid method production inflammable gas is made up of feeder, Reaktionsofen, the water sealing device of slagging tap, cooling tank, purification pot, gas holder.Feeder by opening for feed, sealed materials device, the spiral follower arm is formed.The outlet of feeder links to each other with the import of Reaktionsofen, establish a roller in the Reaktionsofen, establish flight on the roller cylindrical, roller and Reaktionsofen shell spacing are 4cm, are rotated by motor, speed reduction unit driven roller, and roller rotation rate is 10-12 rev/min, the Reaktionsofen top sets out tracheae, the below of Reaktionsofen sets out cinder notch, and slag notch links to each other with the water sealing device of slagging tap, and the water sealing device of slagging tap is the big pond of dress water in one.The Reaktionsofen escape pipe links to each other with cooling tank, and the escape pipe on the cooling tank links to each other with compressor, and the escape pipe of compressor inserts in the scavenging solution of purification pot, and the escape pipe of purification pot links to each other with gas holder by compressor.
Sealing materials device is by cover plate, mistake feed bin about being located on the same Z-axis, drove the gear pair that feed bin rotates, motor, speed reduction unit is formed, it is cylindric crossing feed bin, and bottom surface has two and the symmetric through hole of medullary ray on it, and upper and lower cover plate is with the upper and lower bottom shape of feed bin is the same excessively, just be respectively equipped with one with cross the corresponding hole of feed bin lead to the hole site, and the position in the hole on the upper and lower cover differs 180 °.
The oral area of escape pipe is provided with filter mantle on the Reaktionsofen, in addition on the escape pipe of Reaktionsofen, cooling tank, on the escape pipe of purification pot, all establish tensimeter on the gas holder.Cooling tank bottom, purification pot bottom are established the high pressure flowing water Valve respectively.
Effect of the present invention and technical characterstic:
1, simple, the convenience of drawing materials of technology, low cost of manufacture is easy to promote.
2, production unit is simple in structure, and is easy to operate, reliable.
3, the inflammable gas health of producing, non-environmental-pollution.
Embodiment:
