The second section water-gas reaction

Because coal gangue temperature in pyrolysis vaporizer is higher, then pass into water vapor to coal gangue, the charcoal in coal gangue pyrolysis after product and superheated vapour meet and carry out water-gas reaction generation water-gas (carbon monoxide and hydrogen).

As shown in Fig. 1, Figure 10, Figure 11, water-gas reaction device 7 comprises pyrolysis vaporizer 61, material heat sink 70, steam generation device 75.

As shown in Figure 1, pyrolysis vaporizer 61 is positioned at center support and bends 65 tops, and material heat sink 70, steam generation device 75 are positioned at center support and bend 65 belows.

As shown in Figure 1, shown in Figure 11, material heat sink 70 is arranged on and stretches out body of heater 91 bottoms, comprises high temperature cooling chamber 701, low temperature cooling chamber 702, cooling chamber's bridge bow 703; The top of high temperature cooling chamber 701 communicates with pyrolysis vaporizer 61 bottoms; High temperature cooling chamber 701 and low temperature cooling chamber 702 are setting up and down, and cooling chamber's bridge bow 703 is arranged between high temperature cooling chamber 701 and low temperature cooling chamber 702, and cooling chamber's bridge bow 703 comprises that bridge bow 7031, steam chest 704, steam enter siphunculus 707; Article 4, bridge bow 7031 is partitioned into spoke shape layout at an angle with high temperature cooling chamber 701 and the 702Zhou of low temperature cooling chamber center, bridge bends 7031 middle parts and forms steam chest 704, steam chest 704 is a cylindrical chamber, the top of steam chest 704 is provided with semisphere blast cap 708, and the lower openings of steam chest 704 is towards low temperature cooling chamber 702; Steam enters siphunculus 707 and is arranged in bridge bow 7031, and steam enters siphunculus 707 1 ends and leads to steam chest 704, and the other end stretches out outside body of heater 91.

As Fig. 1, shown in Figure 12, steam generation device 75 comprises annular hollow metal casing 755, steam pockets 754 and drum input tube 751, drum output tube 752, annular hollow metal casing 755 is arranged on body of heater 91 bottoms, the interior annular space chamber 758 of annular hollow metal casing 755 is connected to low temperature cooling chamber 702 bottoms of material heat sink 70, the big up and small down funnel-form of interior annular space chamber 758 annular cavity, 755 casees interior formation of annular hollow metal casing seal the body of heater water bag 753 for storage of water relatively, body of heater water bag 753 is connected to water inlet pipe 756 and drum input tube 751, water inlet pipe 756 communicates with water tank 757, drum input tube 751 is connected with steam pockets 754, the drum output tube 752 of steam pockets 754 enters siphunculus 707 the other ends with the steam of material heat sink 70 and communicates.

Water-gas reaction Principle Method of the present utility model is:

(1), in steam pockets 754, water vapor enters siphunculus 707 by drum input tube 752 and steam and passes into water vapor to the low temperature cooling chamber 702 of material heat sink 70, water vapor blows to low temperature cooling chamber 702, except the cooling of the solid product to after pyrolytic gasification in low temperature cooling chamber 702, water vapor upwards seals in high temperature cooling chamber 701, give the cooling of the high-temp solid product after pyrolysis vaporizer 61 falls into a large amount of pyrolytic gasification of high temperature cooling chamber 701, when the solid of water vapor after giving pyrolytic gasification lowered the temperature, improve vapor temperature and form superheated vapour;

(2), superheated vapour enters pyrolysis vaporizer 61 through center support bow 65, and contact with the high-temperature coal spoil pyrolysis material of pyrolysis vaporizer 61, the charcoal after the coal gangue pyrolysis in solid product and superheated vapour meet and carry out water-gas reaction generation water-gas (carbon monoxide and hydrogen);

(3), solid product after the coal gangue pyrolytic gasification falls into high temperature cooling chamber 701 and the low temperature cooling chamber 702 of material heat sink 70 from pyrolysis vaporizer 61, the water vapor that upwards enters pyrolysis vaporizer 61 to passing through low temperature cooling chamber 702 and high temperature cooling chamber 701 is heated as overheated high-temperature water vapor again, again the solid product after the coal gangue pyrolytic gasification is lowered the temperature simultaneously, in recycling low temperature cooling chamber 702, the solid product waste heat adds the thermosetting water vapor to the water in body of heater water bag 753, water vapor enters in steam pockets 754 by drum input tube 751, give in steam pockets 754 and supplement a large amount of water vapors that consume because of water-gas reaction, make water-gas reaction uninterruptedly to carry out continuously.

The a large amount of generation of water-gas reaction of the present utility model is to carry out in pyrolysis vaporizer 61 middle and lower parts, this is because the pyrolysis of coal gangue in this section pyrolysis vaporizer is relatively abundant, temperature is also relatively high, now from the bottom of pyrolysis vaporizer 61, pass into the water vapor of hyperthermia and superheating, the charcoal in the solid product after overheated water vapor and coal gangue pyrolysis swashs and will produce a large amount of water-gas mutually; Certainly, water vapor is in giving high temperature cooling chamber 701 and low temperature cooling chamber 702 in the solid product temperature-fall period after the coal gangue pyrolytic gasification, also can produce water-gas with charcoal remaining in solid product after the coal gangue pyrolytic gasification, but the amount less produced, this height of charcoal remaining in solid product after this and coal gangue pyrolytic gasification is few, and steam temperature neither be too high relevant.

The waste heat of the solid product that the temperature of the utility model utilization after the coal gangue pyrolytic gasification is relatively low carries out heat transmission and produces water vapor, the recycling water vapor solid product higher with temperature directly contacts the generation superheated vapour, reach the temperature required of water-gas reaction, promote water-gas reaction more to fill part, both when reducing the solid product temperature, produce again water vapor and superheated vapour, this technological method that consumes additional energy source that do not need meets energy-saving and cost-reducing that we advocate today, the theory of Sustainable development.

The 3rd joint raw gas take-up gear

Coal gangue produces the gas containing a lot of useful compositions in the high temperature pyrolysis and gasification process, charcoal in coal gangue pyrolysis after product and superheated vapour carry out water-gas reaction and generate water-gas (carbon monoxide and hydrogen), above general designation raw gas, need to derive in order to utilize raw gas.
