Description

  The present invention relates to a water gas production apparatus for producing hydrogen gas and carbon monoxide gas by spraying superheated steam on a carbonaceous raw material, a water gas production method using this apparatus, and a waste treatment method using waste as a carbonaceous raw material. .

  The water gas is produced by reacting a carbonaceous raw material made of hydrocarbon such as petroleum, LNG (liquefied natural gas), coke and the like with water vapor at a high temperature. The water gas is used not only as a fuel but also as a synthetic chemical raw material such as methanol, formalin, and ammonia, and hydrogen gas is produced by purification. In particular, demand for hydrogen gas is increasing with the spread of fuel cells. However, carbonaceous raw materials such as petroleum, LNG, coke and the like are limited and are expected to be depleted in the future. On the other hand, combustible waste such as municipal waste is on the rise, and its disposal has become a major social problem. Therefore, if water gas can be produced efficiently, a finite carbonaceous raw material can be saved. If waste can be processed and used as energy, it not only contributes to environmental purification, but also helps to solve energy problems.

Under such circumstances, there have been proposals for an apparatus and a method for producing water gas from a carbonaceous raw material such as waste by using superheated steam. For example, an apparatus and method for efficiently producing a water gas by treating a liquid mainly containing a compound containing carbon with superheated steam (see Patent Document 1), an apparatus and method for gasifying organic waste with superheated steam ( (See Patent Document 2). There is also a proposal for an apparatus for generating superheated steam. For example, superheated steam is generated by an apparatus that generates superheated steam by heating steam with a heating heat source (see Patent Document 3), an exciting coil wound around the outer periphery of a cylindrical body, and a breathable heated body made of a conductive material. There are proposals for an apparatus that generates superheated steam (see Patent Document 4) and an apparatus that generates superheated steam using electromagnetic induction heating means (see Patent Document 5).

This is a superheated steam generating housing provided with an inlet 33. At the center of one side plate 31 of the casing 30 for generating superheated steam, a superheated steam discharge cylinder 34 is provided so as to constitute a superheated steam discharge section. Further, the other side plate 32 of the superheated steam generating housing 30 is provided with a mounting plate 35 having a mounting hole 35a having the same diameter as that of the superheated steam generating housing 30 to constitute a burner mounting portion.

It is a rectangular tube-shaped casing for gasification. The superheated steam generation tube B of the superheated steam generator B is inserted into the insertion port 42 and communicated therewith, and is further fixed to the gasification casing 40 by a mounting plate 44 to constitute a superheated steam generator mounting portion. . Moreover, the door 45 is formed in the carbonaceous raw material inlet 43 for charging a carbonaceous raw material, and it can be opened and closed.

Next, the operation of the water gas production apparatus 100 of the present invention configured as described above will be described.
FIG. 1 shows the operation in the continuous operation state of an aerothermal vaporization reburning burner A using backfired heat. The pressurized air supply device D is operated to supply an appropriate amount of pressurized air a to the air duct 4. , The pressurized air a passes between the air duct 4 and the air supply pipe 18, passes through the outer combustion cylinder 1, passes through the air supply pipe 18 and the auxiliary air supply pipe 20, and supplies the fuel supply holes 11 and the ignition supply holes 12. Through the inner combustion cylinder 15. If an appropriate amount of fluid fuel f is supplied from the fuel supply device F through the fuel supply pipe 24 into the inner combustion cylinder 15, the fuel f passes through the combustion air supply pipe 18 and the auxiliary air supply pipe 20 and the combustion air supply holes 11. Turbulent diffusion is caused by the pressurized air a jetted into the inner combustion cylinder 15 through the ignition air supply hole 12 to form a mist, and the ignition is ensured by replenishment of the pressurized air a flowing in from the ignition air supply hole 12. When the ignition device S is operated to ignite and burn the fuel f, the incomplete combustion gas g expands while heating the inner combustion cylinder 15 and increasing the internal pressure, and vaporizes into the peripheral wall cylinder 9 in a vaporized state. The gas is ejected into the outer combustion cylinder 1 from the gas ejection hole 10 provided and the gas discharge hole 13 provided in the cover plate 14.

  Since the rear part in the combustion cylinder 1 becomes a pressure reducing part by the pressurized air a supplied into the outer combustion cylinder 1 from the blower duct 4, the pressurized air a is along the outer periphery of the inner combustion cylinder 15. The gas flows backward, mixes with the incomplete combustion gas g ejected from the inner combustion cylinder 15 into the outer combustion cylinder 1, and repeatedly circulates in the outer combustion cylinder 1 to become a high-temperature gas. In the superheated steam generator B from the gas discharge cylinder 7, the incomplete combustion gas g ejected from the inner combustion cylinder 15 by the back-fire heat of the high-temperature gas that circulates by heating is promoted as the high-temperature complete combustion gas G. To erupt.

  When the overheated steam generating casing 30 of the superheated steam generator B is heated by the complete combustion gas G ejected from the gas discharge cylinder 7 by operating the backfired aerobic aerobic reburning burner A, The water supply device J is operated to supply water j into the superheated steam generating housing 30 through the water supply pipe 36.

  The water j supplied into the superheated steam generating housing 30 is directly heated by the complete combustion gas G, instantaneously becomes superheated steam h, and travels around the inner periphery of the superheated steam generating housing 30. The superheated steam h generated by direct heating in the superheated steam generation housing 30 turns into the superheated steam H at high temperature and high pressure while circulating in the direction of the gas discharge cylinder 7 while circulating in the superheated steam generation cylinder 30. It is discharged from the superheated steam discharge tube 34 into the gasifier C.

  The aerobic re-burning burner A using backfire heat emits a high-temperature, high-energy flame with an extremely high energy convergence rate, with an outlet temperature immediately after ignition of approximately 1500 ° C. Because it burns completely, it does not generate nitrogen oxides, and the fuel gasified at high temperature is swirled repeatedly inside the burner, and it is violently mixed with oxygen and becomes high temperature. Therefore, water can be sprayed or dripped onto the flame to instantaneously generate a superheated steam H having a high temperature of 600 ° C. or higher. In this case, the ratio between the combustion gas and the superheated steam H becomes harmless high-temperature superheated steam H reaching 60% or more depending on the ratio of spraying water. In addition, the scale is used to increase the heating efficiency by swirling or circulating in the superheated steam generation casing 30 by the complete combustion gas G from the aerothermal vaporization reburning burner A using backfired heat and to process it into high-temperature completely mixed steam. Generation | occurrence | production of this can be suppressed and a superheated steam production | generation capability can be maintained.

  The temperature of the superhydrothermal steam produced by a conventional burner is as low as about 300 to 500 ° C., and the steam must be reheated with a boiler or the like in order to make the water gasification reaction 600 to 1000 ° C. I needed a lot of energy. In addition, when superheated steam is produced by electromagnetic induction heating, energy efficiency is low due to electric energy, and large energy is still necessary. However, the reverse-fired aerobic re-burning burner A of the present invention is superior in energy efficiency because it generates a high-temperature flame with the above-described configuration, and instantly gasifies and produces high-temperature superheated steam at 600 ° C. or higher. It can be generated and used by the device itself.

The superheated steam H generated in the superheated steam generator B is sprayed onto the carbonaceous raw material charged into the gasifier C from the carbonaceous raw material inlet 43. Since the water gasification reaction occurs at 600 to 1000 ° C., the following water gasification reaction occurs in the gasifier C due to the high-temperature superheated steam H at 600 ° C. or higher, and carbon monoxide gas and hydrogen gas are generated.
Water gasification reaction: C + H ₂ O → CO + H ₂

The generated carbon monoxide gas and hydrogen gas are discharged from the gas discharge tube 41 and collected. The recovered water gas can be used as a fuel or for the production of methanol or the like. Moreover, hydrogen gas can be used for a fuel cell. Further, the monoxide gas can be used for producing hydrogen by the following water gas shift reaction.
Water gas shift reaction: CO + H ₂ O → CO ₂ + H ₂

  Further, the ash produced by reducing the volume of the carbonaceous raw material by the water gasification reaction is recovered. Although not shown, a hopper may be formed in the lower part of the gasifier C, and the hopper may be temporarily collected therein.

  The carbonaceous raw material mainly means carbonaceous or hydrocarbonaceous matter and also includes waste. Examples of the waste include carbonaceous or hydrocarbon waste such as coffee bean straw, industrial waste, demolished wood of abandoned house, pruning waste of trees, rice husk of agricultural waste, and the like. By using these wastes as the carbonaceous raw material, the waste can be used as an energy source, and the waste can be easily treated by volume reduction.
