The second water saving coal gas reaction
Because gangue temperature in pyrolysis vaporizer is higher, feed water vapour to gangue again, the charcoal in the gangue pyrolysis afterproduct and superheated vapour meet and carry out water gas reaction generation water-gas (carbon monoxide and hydrogen).
As Fig. 1, Figure 10, shown in 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 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 Fig. 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 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 hemispherical 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 Fig. 1, shown in Figure 12, steam generation device 75 comprises annular hollow metal casing 755, steamdrum 754 and drum input pipe 751, drum efferent duct 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 toroidal 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 pipe 751, water inlet pipe 756 communicates with storage tank 757, drum input pipe 751 is connected with steamdrum 754, and the drum efferent duct 752 of steamdrum 754 enters siphunculus 707 other ends with the steam of material heat sink 70 and communicates.
Water gas reaction principle method of the present invention is:
(1), water vapour enters siphunculus 707 to the low temperature cooling chamber 702 feeding water vapours of material heat sink 70 by drum input pipe 752 and steam in the steamdrum 754, water vapour blows to low temperature cooling chamber 702, the solid product cooling in giving low temperature cooling chamber 702 behind the pyrolytic gasification, water vapour 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 vapour after giving pyrolytic gasification lowered the temperature, improve vapor (steam) temperature and form superheated vapour;
(2), superheated vapour passes central supported bow 65 and enters pyrolysis vaporizer 61, and contact with the high temperature gangue pyrolysis material of pyrolysis vaporizer 61, the charcoal after the 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 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 vapour 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 gangue pyrolytic gasification is lowered the temperature simultaneously, the solid product waste heat adds the thermosetting water vapour for the water in the body of heater water bag 753 in the recycling low temperature cooling chamber 702, water vapour enters in the steamdrum 754 by drum input pipe 751, give and replenish a large amount of water vapours that consume because of water gas reaction in the steamdrum 754, make water gas reaction uninterruptedly to carry out continuously.
The a large amount of generation of water gas reaction of the present invention is to carry out in pyrolysis vaporizer 61 middle and lower parts, this is because the gangue pyrolysis in this section pyrolysis vaporizer is abundant relatively, temperature is also higher relatively, feed the water vapour of hyperthermia and superheating this moment from the bottom of pyrolysis vaporizer 61, the charcoal in the solid product after overheated water vapour and the gangue pyrolysis is sharp mutually will to produce a large amount of water-gas; Certainly, water vapour is in giving high temperature cooling chamber 701 and low temperature cooling chamber 702 in the solid product temperature-fall period behind the gangue pyrolytic gasification, also can produce water-gas with charcoal remaining in the solid product behind the gangue pyrolytic gasification, but the amount that produces is less relatively, this height of charcoal remaining in the solid product behind this and the gangue pyrolytic gasification is few, and steam temperature neither be too high relevant.
The waste heat of the solid product that the temperature of utilization of the present invention behind the gangue pyrolytic gasification is relatively low carries out heat transmission and produces water vapour, the higher solid product of recycling water vapour 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 vapour and superheated steam again, this technical 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.
