The second water saving coal gas reaction
Because coal gangue temperature in pyrolysis vaporizer is higher, feed water vapor to coal gangue again, the charcoal in the coal gangue pyrolysis after product and superheated vapour meet and carry out water-gas reaction generation water-gas (carbon monoxide and hydrogen).
As Figure 11, Figure 20, shown in Figure 21, water-gas reaction device 7 comprises pyrolysis vaporizer 61, material heat sink 70, steam generation device 75.
As shown in figure 11, pyrolysis vaporizer 61 is positioned at central supported and bends 65 tops, and material heat sink 70, steam generation device 75 are positioned at central supported and bend 65 belows.
As Figure 11, shown in Figure 21, 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 upper and lower settings, cooling chamber's bridge bow 703 is arranged between high temperature cooling chamber 701 and the 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 702 centers of high temperature cooling chamber 701 and low temperature cooling chamber, 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 the bridge bow 7031, and steam enters siphunculus 707 1 ends and leads to steam chest 704, and the other end stretches out outside the body of heater 91.
As Figure 11, shown in Figure 22, 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 installed in 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 cavities, 755 casees interior formation of annular hollow metal casing seal the body of heater water bag 753 that is used 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, and 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), water vapor enters siphunculus 707 to the low temperature cooling chamber 702 feeding water vapors of material heat sink 70 by drum input tube 752 and steam in the steam pockets 754, water vapor blows to low temperature cooling chamber 702, the solid product cooling in giving low temperature cooling chamber 702 behind the pyrolytic gasification, water vapor upwards seals in high temperature cooling chamber 701, give the high-temp solid product cooling 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 passes central supported bow 65 and enters pyrolysis vaporizer 61, and contact with the high temperature coal gangue pyrolysis material of pyrolysis vaporizer 61, the charcoal after the coal gangue pyrolysis in the solid product and superheated vapour meet and carry out water-gas reaction and generate water-gas (carbon monoxide and hydrogen);
(3), solid product behind 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 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 behind the coal gangue pyrolytic gasification is lowered the temperature simultaneously, the solid product waste heat adds the thermosetting water vapor for the water in the body of heater water bag 753 in the recycling low temperature cooling chamber 702, water vapor enters in the steam pockets 754 by drum input tube 751, give and replenish a large amount of water vapors that consume because of water-gas reaction in the steam pockets 754, 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 coal gangue pyrolysis in this section pyrolysis vaporizer is abundant relatively, temperature is also higher relatively, feed the water vapor of hyperthermia and superheating this moment from the bottom of pyrolysis vaporizer 61, the charcoal in the solid product after overheated water vapor and the coal gangue pyrolysis is sharp mutually will to produce a large amount of water-gas; Certainly, water vapor is in giving high temperature cooling chamber 701 and low temperature cooling chamber 702 in the solid product temperature-fall period behind the coal gangue pyrolytic gasification, also can produce water-gas with charcoal remaining in the solid product behind the coal gangue pyrolytic gasification, but the amount that produces is less relatively, this height of charcoal remaining in the solid product behind this and the 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 behind the coal gangue pyrolytic gasification is relatively low carries out heat passage generation water vapor, the higher solid product of recycling water vapor and temperature directly contacts the generation superheated vapour, reach the temperature required of water-gas reaction, promote water-gas reaction to fill part more, both when reducing the solid product temperature, produce water vapor and superheated vapour again, this technological method that does not need to consume additional energy source 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 that contains a lot of useful compositions in the high temperature pyrolysis and gasification process, charcoal in the coal gangue pyrolysis after product and superheated vapour carry out water-gas reaction and generate water-gas (carbon monoxide and hydrogen), more than be referred to as raw gas, need derive in order to utilize raw gas.
As Figure 11, Figure 18, shown in Figure 19, raw gas take-up gear 8 comprises raw gas concentration chamber 81, interior derivation passage 82, derives passage 83 outward, derives main channel 84, derives circuit 85; It is integrally formed that raw gas concentration chamber 81 is arranged on top and the pyrolysis vaporizer 61 of pyrolysis vaporizer 61; As Figure 11, shown in Figure 180, article 6, deriving passage 82 in arranges in the quirk partition wall 635, pyrolysis vaporizer 61 was led at ringwall 612 middle parts in interior derivation feeder connection 821 passed, the raw gas concentration chamber 81 that ringwall 612 led to the pyrolysis vaporizer top in interior derivation channel outlet 822 was passed; As Figure 11, shown in Figure 180, article 6, the outer passage 83 of deriving arranges in the exterior wall of body of heater 91, derive feeder connection 831 down outward, go up the outer feeder connection 834 of deriving and pass outer ring wall 611 middle parts and lead to pyrolysis vaporizer 61, derive channel outlet 832 outward and pass the raw gas concentration chamber 81 that outer ring wall 611 leads to the pyrolysis vaporizer top.
