(Points of interest)
With the recent increase in power demand, coal-fired power plants have been reviewed, and along with this, the amount of new ash generated has increased significantly. Due to the recent economic downturn and global warming problems, new ash has become a raw material for cement. In addition, it has been used effectively as an admixture for concrete, and the surplus ash that has not been effectively used has been disposed of in landfills as industrial waste. The total amount of these deposits is increasing, and in each municipality that properly disposes of such industrial waste, the issue of depletion of landfill sites is urgent. The development of new technology that enables more efficient and effective use of newly generated new ash is an urgent issue.

    Under these circumstances, the conventional coal-fired power plant, as shown in FIG. 2, is a dry ash NC (sinter fly ash mixture, which is generated as the coal boiler P0 that is in operation burns coal fuel. As shown by the broken line arrow in FIG. 2, high-temperature exhaust gas containing ash DC (hereinafter the same) passes through the economizer A1 and the air preheater A2 on the way through the exhaust pipe P1. While removing the heat, the sinter DC (new ash NC, hereinafter the same) is also separated and recovered, and most of the fly ash DC (new ash NC, hereinafter the same) contained in the exhaust gas by the electrostatic precipitator A3. .) Is removed and purified, and then discharged into the outside air. The fresh ash NC separated and recovered by the economizer A1, the air preheater A2, and the electrostatic precipitator A3 is once the first Accumulated in silo S1 After that, the accumulated new ash NC is partly humidified ash WC so that dust does not scatter in the humidifier S2, according to the treatment plan and transport plan, and is loaded on the dunk truck T1 and transported to the destination. Further, the other part is transported to the destination by appropriate transport means T such as a jet pack car T2 or a ship T3, and the other part of the new ash NC left in the first silo S1 is a classifier S3. Are distributed and accumulated in the second silo S4 and the third silo S5 for each particle size, and after passing through the humidifier S2 and the bagging machine S6, respectively, depending on the purpose. To be transported to.

After accumulating in S7, passing through the crusher S8 and dewatering tank S9 according to the shipping plan, and passing through the sieve S10 as necessary, it is transported to the destination by various transportation means T according to the purpose. These new ash NCs (dry ash DC, which is a mixture of sinter and fly ash. The same applies hereinafter) are shipped as so-called JIS ash according to Japanese Industrial Standards by the classification process as described above. The new ash NC that could not be exhausted must be landfilled as industrial waste at the final disposal site. Currently, there is a technology that can quickly solve the problem of depletion of the landfill disposal site. Because it is not did not get to say that the actual situation.

If the water content is less than 5%, it takes time to mix with the cement, resulting in inconvenience in the process. In addition, if the water content exceeds 50%, it takes a long time for the cement to harden and the strength after hardening decreases. Therefore, it is desirable to control the moisture content of the new ash to 25% ± 5 in order to obtain the new high density and high strength new ash recycled concrete product most efficiently. The automatic control device should be able to control the moisture content of the total amount of new ash charged into and mixed in the kneading device to 25% ± 5 with high accuracy.

(Points of interest)
With the recent increase in power demand, coal-fired power plants have been reviewed, and along with this, the amount of new ash generated has increased significantly. Due to the recent economic downturn and global warming problems, new ash has become a raw material for cement. In addition, it has been used effectively as an admixture for concrete, and the surplus ash that has not been effectively used has been disposed of in landfills as industrial waste. The total amount of these deposits is increasing, and in each municipality that properly disposes of such industrial waste, the issue of depletion of landfill sites is urgent. The development of new technology that enables more efficient and effective use of newly generated new ash is an urgent issue.

    Under these circumstances, the conventional coal-fired power plant, as shown in FIG. 2, is a dry ash NC (sinter fly ash mixture, which is generated as the coal boiler P0 that is in operation burns coal fuel. As shown by the broken line arrow in FIG. 2, high-temperature exhaust gas containing ash DC (hereinafter the same) passes through the economizer A1 and the air preheater A2 on the way through the exhaust pipe P1. While removing the heat, the sinter DC (new ash NC, hereinafter the same) is also separated and recovered, and most of the fly ash DC (new ash NC, hereinafter the same) contained in the exhaust gas by the electrostatic precipitator A3. .) Is removed and purified, and then discharged into the outside air. The fresh ash NC separated and recovered by the economizer A1, the air preheater A2, and the electrostatic precipitator A3 is once the first Accumulated in silo S1 After that, the accumulated new ash NC is partly humidified ash WC so that dust does not scatter in the humidifier S2, according to the treatment plan and transport plan, and is loaded on the dunk truck T1 and transported to the destination. Further, the other part is transported to the destination by appropriate transport means T such as a jet pack car T2 or a ship T3, and the other part of the new ash NC left in the first silo S1 is a classifier S3. Are distributed and accumulated in the second silo S4 and the third silo S5 for each particle size, and after passing through the humidifier S2 and the bagging machine S6, respectively, depending on the purpose. To be transported to.

After accumulating in S7, passing through the crusher S8 and dewatering tank S9 according to the shipping plan, and passing through the sieve S10 as necessary, it is transported to the destination by various transportation means T according to the purpose. These new ash NCs (dry ash DC, which is a mixture of sinter and fly ash. The same applies hereinafter) are shipped as so-called JIS ash according to Japanese Industrial Standards by the classification process as described above. The new ash NC that could not be exhausted must be landfilled as industrial waste at the final disposal site. Currently, there is a technology that can quickly solve the problem of depletion of the landfill disposal site. Because it is not did not get to say that the actual situation.

Granule manufacturing method, using coal ash granulated product Manufacturing methods of concrete products, high-density and high-strength concrete products manufactured by these manufacturing methods, methods of manufacturing recycled aggregates using the high-density and high-strength concrete products, and recycled bones manufactured by this manufacturing method According to the “materials” invention, it has already been developed that a technique for recovering and recycling the ready-made ash once disposed at the landfill site.

However, as disclosed in Patent Document 1 (1), “a method for producing a coal ash granulated product, a method for producing a concrete product using the coal ash granulated product, and a high density / high density produced by the production method.

After that, based on the shipping plan, it is still necessary to transport to the destination by various means of transportation T, and the sinter fly ash mixture and the clinker ash that the coal-fired power plant P continues to be generated every day. It has not been possible to solve the problem of requiring a great deal of labor and cost for the accumulation management and disposal of new ash.

It is intended to be shipped and transported from storage facilities to external factories and disposal sites, etc., such as new ash storage facilities, dump trucks that can handle long-distance transport of new ash, jet pack vehicles, transport vessels, etc. Although it required a great deal of labor and expense, it has eliminated the need for independent facilities for accumulating and storing new ash, such as dry ash receiving silos and clinker yards, which have been indispensable. In addition, the cement obtained in a predetermined ratio with respect to a predetermined amount of the new ash and mixing water having a predetermined ratio with respect to the new ash and the cement are pulverized, mixed, and kneaded to obtain a new ash kneaded product. As a result, the production cost of the new ash kneaded product can be greatly reduced, and the excellent feature that the new ash transported to the landfill site can be substantially eliminated can be obtained.

    In addition, there is a kneading plant installed in the FRC concrete manufacturing plant, which separates and isolates the material supply system to the kneading equipment into a total of three supply paths: a new ash supply path, an adhesive supply path, and a water supply path. By using it, fresh ash is supplied to the new ash supply path, cement is supplied to the solidification material supply path, and mixing water is supplied to the water supply path in an isolated state, thereby accurately controlling the amount of water when it is introduced into the kneader.

The manufacturing method of the new ash kneaded product according to the present invention includes a sinter / fly ash mixture, which is dry ash discharged from a coal boiler such as a coal-fired power plant, and a new ash such as clinker ash that has been crushed and adjusted in particle size. Is a new technology for producing new ash kneaded products and new ash kneaded products that can be effectively used as new ash artificial aggregates, etc., and is used for the material supply system of kneading plants in concrete manufacturing plants When using only a sinter fly ash mixture, it is not necessary to select the particle size, but whether the clinker ash having a large particle size is used alone or mixed with the sinter fly ash mixture. When either one is used, it is sorted into a predetermined particle size at an appropriate time before charging into the kneading apparatus, the particle size constitution is 0 to 40 mm, and 20 It is better to set the ratio of 80% for m-under and 90% for optimal value, and 90% for 5mm-under. The sorted and eliminated 40mm-over new ash is supplied to the crushing path, pulverized, and then sorted again. It is convenient to use it after performing.

    In addition, it is possible to produce a new ash kneaded product by introducing only a sinter / fly ash mixture into a kneader without using a clinker ash having a large particle size. When only one of the ash is put into the kneading apparatus to produce a new ash kneaded product, and all the new ash with a particle size under 40 mm is put into the kneading apparatus For example, the fresh ash can be directly added to the kneader without producing a sorting process to produce a fresh ash kneaded product, and when mixing clinker ash with a high water content. Is preferably mixed with an appropriate amount of at least one of sinter and fly ash so that the water content is controlled within the range of 5 to 50%, preferably 25% ± 5, From the beginning the raw ash supply path turned, when the water content of the clinker ash is in the range of 25% ± 5 may sometimes kneading without any mixing sintering and fly ash.

Ones that is desirable.

    The material supply system to the kneading apparatus of the kneading plant used in the method for producing the new ash kneaded product according to the present invention allows the new ash, cement, and mixing water to be supplied to the kneading apparatus while keeping the separated state of each other. For example, the clinker ash supply path is separated and separated into a total of four supply paths: a sinter / fly ash supply path, a clinker ash supply path, a solidified material supply path, and a water supply path. It is most desirable that a moisture meter for measuring the moisture content of clinker ash is provided at an appropriate location, and the kneading plant supplies fresh ash supplied by mixing and supplying a sinter fly ash mixture, clinker ash, etc. It is separated and separated into a total of three supply channels, a solidification material supply channel and a water supply channel. Moisture meter can be made by providing a for.

    The sinter fly ash supply channel makes it possible to efficiently supply the sinter fly ash mixture as dry ash from the new ash discharged from the coal-fired power plant to the kneading equipment. Responsible for preventing the sinter and fly ash mixture received in the supply path from leaking to the outside, and preventing water and foreign matter from entering the inside from the outside, more specifically, As shown in the examples to be described later, it is possible to receive, store and store a sinter / fly ash mixture collected from a coal boiler such as a coal-fired power plant and carried to the kneading plant by a transportation means such as a jet-back vehicle. The dry ash receiving silo, which is responsible for the function to perform, the appropriate amount of the sinter / fly ash mixture stored in the dry ash receiving silo, Weighed and weighed the amount of dry ash service silo that shared the functions that could be supplied to the sinter and the sinter / fly ash mixture supplied from the dry ash service silo to produce the new ash kneaded product. It is preferable to have a dry ash metering hopper capable of supplying a quantity of sinter and fly ash mixture to the kneading apparatus.

The water content of the total amount of fresh ash charged into the kneading apparatus must be controlled to 5 to 50%. If the water content is less than 5%, it takes time to mix with the cement, resulting in inconvenience in the process. In addition, if the water content exceeds 50%, it takes a long time for the cement to harden and the strength after hardening decreases. Therefore, it is desirable to control the moisture content of the new ash to 25% ± 5 in order to obtain the new high density and high strength new ash recycled concrete product most efficiently. The automatic control device should be able to control the moisture content of the total amount of new ash charged into and mixed in the kneading device to 25% ± 5 with high accuracy.
