Description

  The present invention relates to an apparatus and a manufacturing method for a melt, and more particularly to an apparatus and a manufacturing method for a melt that can be suitably used for manufacturing a cement clinker.

  To produce cement, powder raw material mainly composed of limestone is passed through a pre-heater and calcining furnace, and then fired at a high temperature of 1,450 ° C or higher in a rotary kiln to produce hydraulic cement clinker. Then add gypsum and mixed material to the cement clinker and pulverize. Therefore, a large amount of energy is consumed in the cement manufacturing process.

  Due to the growing interest in environmental issues such as global warming in recent years, the cement industry, which consumes a large amount of energy, is required to respond more than ever to the depletion of spatial resources and the suppression of carbon dioxide emissions. In cement production, various types of waste are used as fuel substitutes, contributing to waste treatment, and reducing the basic unit of fossil fuel, and so on. .

  As part of this, for example, Patent Document 1 discloses that low-grade coal is efficiently burned by utilizing the combustion performance, heat transfer performance, particle diffusion and granulation characteristics inherent to fluidized bed processes, and NOx emissions are reduced. A fluidized bed cement calcining kiln system has been proposed that can significantly reduce environmental impacts and improve the efficiency of heat recovery from materials and gases discharged from the process, and that can support global environmental conservation and energy saving.

JP-A-8-81245

  However, the fluidized bed cement calcined kiln system described in Patent Document 1 still uses fossil fuel and generates carbon dioxide from the burned fossil fuel, so there is room for improvement in terms of suppressing carbon dioxide emission. Further, in the fluidized bed process, it is necessary to supply air to the calcining furnace in order to fluidize the raw material, and thus it has been impossible to avoid a decrease in thermal efficiency due to heating of the air.

  Therefore, the present invention has been made in view of the problems in the above-described conventional technology, and an object thereof is to provide a melt production apparatus and a production method that are excellent in both carbon dioxide emission suppression and thermal efficiency. To do.

  In order to achieve the above object, the present invention provides an apparatus for producing a melt, which comprises an air-fuel mixture generating means for generating an air-fuel mixture of oxygen and hydrogen, and an air-fuel mixture from the air-fuel mixture generating means. A heating furnace that contacts and melts a flame generated by burning the gas, and a power generation means that generates power using the exhaust gas of the heating furnace and supplies the generated power to the mixture generation means . Here, the mixed gas of oxygen and hydrogen may be a mixture of oxygen and hydrogen generated separately, or may be a so-called oxyhydrogen gas obtained by electrolyzing water. In the case where oxygen and hydrogen are separately generated, the mixing ratio is preferably about 1: 2.

  Since the mixture of oxygen and hydrogen can locally generate a high temperature of 2000 ° C., the raw material can be rapidly melted by bringing this high-temperature flame into contact with the supplied raw material. Here, only the water vapor is generated by the combustion of the oxygen / hydrogen mixture itself, and there is no secondary adverse effect due to carbon dioxide or NOx, and it is not necessary to raise the temperature of these gases. Become. In addition, in the heating furnace, it is sufficient to provide a burner that emits a flame and a moving path of the melt, so that a compact and highly efficient apparatus can be configured. In addition, since the electric energy required to generate the mixture of oxygen and hydrogen is very small, the operating cost can be kept low.

  Moreover, since the exhaust gas from the heating furnace is guided to the power generation means, and heat is recovered and used for power generation, the thermal energy generated in the manufacturing apparatus can be effectively used. Furthermore, since the generated electric power is supplied to the air-fuel mixture generating means and used for the electric power required to generate the air-fuel mixture, a part of the electric power necessary for the operation can be covered inside the manufacturing apparatus. Thereby, the dependence on the received electric power from the outside can be reduced, and it becomes possible to further reduce the emission amount of carbon dioxide.

  In the melt production apparatus, the power generation means can generate power using exhaust gas discharged from a high temperature region on the melt outlet side of the heating furnace. Since power generation is performed using high-temperature exhaust gas existing in the high-temperature region, power generation efficiency can be improved, and thermal energy generated in the manufacturing apparatus can be efficiently reused.

  In the melt production apparatus, the heating furnace has a partition wall provided between a high temperature region on the melt outlet side and a low temperature region on the raw material inlet side, and the power generation means is discharged from the high temperature region. It is possible to generate electricity using the exhaust gas. The partition provided in the heating furnace can prevent contact between the high-temperature exhaust gas present in the high-temperature region and the low-temperature exhaust gas present in the low-temperature region, and can suppress the temperature of the high-temperature exhaust gas from decreasing. In addition, since the power generation means generates power using the exhaust gas discharged from the high temperature region, the exhaust gas from the heating furnace can be appropriately used for power generation.

  In the melt production apparatus, a bulk material can be supplied to the heating furnace, and the heating furnace can be brought into contact with the bulk material and melted. According to this, since the prior pulverization work becomes unnecessary or even when the pulverization work is performed, the degree of pulverization can be kept light, so that the equipment cost can be reduced and the work efficiency can be improved. Is possible.

  The melt production apparatus may further include a condenser that condenses moisture contained in the exhaust gas from the heating furnace to generate water, and supplies the water to the mixture generation means. According to this, water vapor generated in the heating furnace can be effectively used.

  In the melt production apparatus, the condenser includes a first condenser that generates water by condensing moisture contained in the exhaust gas after passing through the power generation means, and a raw material inlet side of the heating furnace. And a second condenser for generating water by condensing moisture contained in the exhaust gas discharged from the low temperature region.

  The melt manufacturing apparatus includes a cooling unit that injects and cools at least one of water, water-containing material, and water vapor to the melt discharged from the heating furnace, and the exhaust gas from the heating furnace is supplied to the cooling unit. In addition, the power generation means can be supplied together with the exhaust gas generated in the cooling means.

  In the melt production apparatus, the cooling means includes a pipe line having one end closed and the other end opened, and a nozzle inserted into the closed end part of the pipe line. While supplying the melt which melted by making the flame of a burner contact, at least one or more out of water, hydrated matter, and water vapor from the nozzle is injected into the melt, and the water is cooled while cooling the melt. The coolant can be crushed by at least one of explosion due to evaporation, explosion due to evaporation of water contained in the water-containing material, and expansion of the water vapor. As a result, the melt can be rapidly cooled and the rapidly crushed material can be crushed almost simultaneously using a single device, the crushed material of the rapidly cooled material can be obtained with a simple device configuration, and the operation of the device is easy. is there. In addition, since the melt can be finely crushed during the cooling process of the melt, a subsequent pulverization operation becomes unnecessary, or the degree of pulverization can be kept light, reducing equipment costs and improving work efficiency. Improvements can be made.

  In the melt production apparatus, the heating furnace includes a plurality of burners, and the air-fuel mixture can be burned only by the burner downstream of the raw material flow among the plurality of burners. In burners other than the most downstream burner, fuel obtained from waste, fossil fuel, etc. can be used. In this case, carbon dioxide is generated from these fuels, while oxygen and The amount of electric power for generating the hydrogen gas mixture can be reduced.

  In the melt production apparatus, the heating furnace may be a moving tank type, a rotary kiln type, a fluidized bed type, or a rotary hearth type.

  Further, the present invention is a method for producing a melt, wherein a mixture of oxygen and hydrogen is generated, a flame generated by burning the mixture is brought into contact with the supplied raw material, and the raw material is melted. It is characterized by generating electric power using the exhaust gas generated when melting the gas, and using the generated electric power for the electric power required to generate the air-fuel mixture. According to the present invention, similarly to the above-described invention, when producing a melt, it is possible to suppress the discharge of carbon dioxide and ensure high thermal efficiency.

  As described above, according to the present invention, it is possible to provide a melt production apparatus and a production method that are excellent in terms of both suppression of carbon dioxide emission and thermal efficiency.

In the process, the melt M is split while being blown off by explosion caused by evaporation of the water W1, and the melt M is split. Is put on the water vapor stream and moved to the left end side at high speed. Then, the rapidly cooled object Q discharged from the pipe 9a collides with the impact plate 9d, and is further crushed by the impact. The quenching device 9 can be provided not only in one unit as shown, but also in a plurality of stages depending on the cooling performance or the like.

  The power generation device 11 includes a water tube boiler 11a that generates steam S from the exhaust gas G3 discharged from the chamber 9c of the quenching device 9, a steam turbine 11b and a generator for generating power using the steam S generated in the water tube boiler 11a. 11c.

  The water tube boiler 11a is provided to generate steam S using the heat held by the exhaust gas G3, and the steam turbine 11b is rotated by the steam S generated by the water tube boiler 11a and generates electricity by the generator 11c. . The electric power generated by the generator 11 c is supplied to the oxyhydrogen production device 4 and the auxiliary heating device via the power lines 16 and 17, respectively, and can be used for producing the oxyhydrogen OH and heating the heating furnace 2.

  A condenser 12 is provided downstream of the water tube boiler 11a to condense moisture contained in the exhaust gas G4 that has passed through the water tube boiler 11a and return it to the water W1. The condenser 12 is connected with a pipe 13 for conveying the condensed water W1 to the oxyhydrogen production apparatus 4 and a pipe 14 for conveying the water W1 to the nozzle 9b of the quenching apparatus 9.

  The fan 15 is provided for attracting the exhaust gas G3 from the chamber 9c of the quenching device 9 and guiding it to the water tube boiler 11a and the condenser 12 and for attracting the low temperature exhaust gas G2 from the low temperature region 2L of the heating furnace 2 to the condenser 7. .

  Next, operation | movement of the manufacturing apparatus 1 of the melt which has the said structure is demonstrated, referring FIG.

  In addition to generating oxyhydrogen OH in the oxyhydrogen production apparatus 4, the auxiliary heating apparatus is operated to heat the heating furnace 2. After the fan 15 is operated, the bulk material R prepared in a predetermined composition is charged into the hopper 6a of the supply device 6 and supplied to the heating furnace 2 through the screw feeder 6b.

  Inside the heating furnace 2, the raw material R is moved in the lower left direction while being heated by the auxiliary heating device, and the high-temperature flame generated by burning the oxyhydrogen OH injected from the burner 3 into the raw material R that has become high temperature. And the raw material R is melted.

  At the time described above, steam is generated by the combustion of the oxyhydrogen OH, and carbon dioxide is generated from the heated raw material R. Therefore, the mixed gas stays in the heating furnace 2. Then, the exhaust gas G2 in the low temperature region 2L is extracted by the extraction duct 6c of the supply device 6, and the exhaust gas G2 is guided to the capacitor 7 while preheating the raw material R in the supply device 6. Next, the condenser 7 condenses moisture contained in the exhaust gas G2, and transports the generated water W2 to the oxyhydrogen production apparatus 4 for use in the production of oxyhydrogen OH.

  On the other hand, on the outlet side of the heating furnace 2, the melted raw material (melt) M is supplied to the quenching device 9, and in the quenching device 9, water W <b> 1 is injected into the melt M from the nozzle 9 b. Then, the melt M is rapidly cooled by the water W1, and the water W1 injected into the pipe line 9a is vaporized to become steam S1, and further expands.

  Here, since the right end portion side of the pipe line 9a is closed, the water vapor S1 generated by the vaporization and expansion of the water W1 moves at high speed in the left direction in the pipe line 9a. And the molten material M in the pipe line 9a moves at high speed in the left direction by the steam flow while being shredded by the explosion caused by the evaporation of the water W1. The rapidly cooled object Q discharged from the pipe line 9a collides with the collision plate 9d and is further finely crushed, and then discharged as a cement clinker CL from the discharge portion 9e of the chamber 9c.

  In parallel with the above processing, in the heating furnace 2, the exhaust gas G1 in the high temperature region 2H is guided to the chamber 9c of the quenching device 9 through the exhaust duct 2f. Then, the mixed gas G3 of the water vapor S1 and the exhaust gas G1 in the chamber 9c is attracted by the fan 15 and supplied to the water tube boiler 11a of the power generator 11.

  Next, the water pipe boiler 11a generates the steam S using the heat held by the exhaust gas G3, and the generated steam S is supplied to the steam turbine 11b and rotated to generate power by the generator 11c. At the same time, the exhaust gas G4 that has passed through the water tube boiler 11a is guided to the condenser 12, and the condenser 12 condenses the moisture contained in the exhaust gas G4. The condensed water W1 is conveyed to the oxyhydrogen production apparatus 4 and used for the production of oxyhydrogen OH, and is conveyed to the quenching apparatus 9 and utilized as the cooling water W1 for the melt M.

  In the state where the melt production apparatus 1 is continuously operated, the power P1 generated by the power generation apparatus 11 in addition to the received power P2 can be used by the oxyhydrogen production apparatus 4 and the auxiliary heating apparatus.

  As described above, according to the present embodiment, the raw material R is melted using a flame in which oxyhydrogen OH is burned without using fossil fuel for melting the raw material. Since only the water vapor is generated by the combustion of the oxyhydrogen OH, carbon dioxide from the fuel is not generated, and emission of carbon dioxide can be suppressed. Although carbon dioxide generated from the raw material R exists, there is no secondary adverse effect due to carbon dioxide and NOx from the conventional fuel, and there is no heat loss due to the temperature rise of these gases.

  In addition, since the exhaust gas G1 from the heating furnace 2 is guided to the power generation device 11 and recovered and used for power generation, the heat energy generated in the manufacturing device 1 can be used effectively. Furthermore, since the generated electric power is supplied to the oxyhydrogen production apparatus 4 and used for the electric power required to generate the oxyhydrogen OH, a part of the electric power necessary for the operation can be provided inside the production apparatus 1. Thereby, the dependence on the received power P2 from the outside can be reduced, and it becomes possible to further reduce the discharge amount of carbon dioxide.

  In addition, since the raw material R is melted in the heating furnace 2, a bulk raw material can be used as the raw material supplied to the heating furnace 2. This eliminates the need for prior pulverization work, or even when pulverization work is performed, the degree of pulverization can be kept light, thereby reducing equipment costs and improving work efficiency. become.

  Furthermore, by using the quenching device 9, the melt M can be rapidly cooled and the quenching product Q can be crushed almost simultaneously using one device, and the crushed product of the quenching product Q can be obtained with a simple device configuration. The operation of the device is easy. Further, since the melt M can be finely crushed during the cooling process of the melt M, a subsequent pulverization operation becomes unnecessary, or the degree of pulverization can be kept light, and the burden of the product pulverization mill is reduced. It becomes possible to reduce.

  Furthermore, since the melt production apparatus 1 can be made compact, it is possible to maintain a high temperature atmosphere by effectively insulating the heating furnace 2, the quenching apparatus 9, and the like, and a high thermal efficiency melt. The manufacturing apparatus can be realized.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above-described configuration, and various modifications can be made within the scope of the invention described in the claims.

  For example, in the above embodiment, the burner 3 and the auxiliary heating device are provided in the heating furnace 2, but the auxiliary heating device is provided as an auxiliary, and it is not always necessary to provide the auxiliary heating device. The raw material R can be melted by only 3.

  Moreover, in the said embodiment, although the exhaust gas G1 of the high temperature area | region 2H of the heating furnace 2 is guide | induced to the chamber 9c of the rapid cooling apparatus 9, the exhaust gas G1 is guide | induced to the gas pipe line 18 which connects the chamber 9c and the water pipe boiler 11a, and quenching is carried out. You may make it supply to the water pipe boiler 11a, without passing through the apparatus 9. FIG.

  Further, it is not always necessary to burn the oxyhydrogen OH in all of the burners 3A to 3D, but the oxyhydrogen OH is burned only by the burner 3A on the most downstream side as viewed from the flow of the raw material R, and in the other burners 3B to 3D The raw material R can also be heated using fuel obtained from waste, fossil fuel, or the like. When these fuels are burned, carbon dioxide and the like are generated. However, since carbon dioxide is also generated by heating the raw material R, the carbon dioxide discharged from the melt production apparatus 1 by the combustion of the fuel. Since the total amount of NO does not increase drastically and the oxyhydrogen OH is not burned by the burners 3B to 3D, which leads to a reduction in the amount of electric power, which one can be selected as appropriate according to the situation.

  In the above embodiment, the case where the cement raw material R is melted by the melt production apparatus 1 to produce the cement clinker CL has been described as an example. However, in addition to the cement clinker CL, various cement minerals and quick setting materials are used. When manufacturing materials other than hydraulic materials such as raw materials and glassy compositions, and hydraulic materials such as molten slag (for example, they can be used as aggregates), the melt manufacturing apparatus 1 can be suitably used. . Furthermore, harmful substances such as asbestos and asbestos-containing substances can be used as raw materials in the melt production apparatus 1 and can be rendered harmless by melting them.

  Furthermore, although the oxyhydrogen OH produced by the oxyhydrogen production apparatus 4 was used in the burner 3, oxygen and hydrogen were generated separately without using the oxyhydrogen production apparatus 4, and the mixed one was supplied to the burner 3. And may be burned.

  Moreover, although the case where the moving tank type heating furnace 2 was used was demonstrated in the said embodiment, the rotary kiln type, fluidized bed type, or rotary hearth furnace type heating furnace conventionally used for the cement manufacturing apparatus was used. It can also be used. Here, as an example of a rotary hearth-type heating furnace, a raw material (melted material) is introduced into an annular furnace body frame whose inside is hollowed, and from the side of the furnace body frame, Some radiate a flame toward the raw material and melt the raw material while rotating the furnace frame once.

  Further, instead of injecting water W from the nozzle 9b of the rapid cooling device 9, the water-containing material is injected into the melt M, while the melt M is cooled, It can also be crushed. Moreover, water vapor | steam can be sprayed on the melt M from the nozzle 9b, and the rapidly cooled thing Q can also be crushed by expansion | swelling of water vapor | steam. Further, the water W and the hydrated material may be simultaneously ejected from the nozzle 9b.

  In the above embodiment, the exhaust gas G3 from the chamber 9c of the quenching apparatus 9 is guided to the water tube boiler 11a and used as a heat source for generating the water vapor S. However, if there is no foreign matter in the exhaust gas G3, If it can be removed, the exhaust gas G3 may be guided to the steam turbine 11b, and the steam turbine 11b may be rotated by the exhaust gas G3.

  Furthermore, in the above embodiment, the exhaust gas G2 from the raw material inlet side of the heating furnace 2 is guided to the capacitor 7 to generate water W2. However, without providing the capacitor 7, the exhaust gas G2 is released into the atmosphere or reaches the dew point. It can also be used for preheating and drying the raw materials as long as they are not.
