``Method of generating electricity in the granulated slag manufacturing process'' Now, to briefly explain this prior art based on the description of the specification, molten slag discharged from a blast furnace or the like is cooled and crushed by blowing means that injects cooling water to the molten slag,
Using the hot water whose cooling water has reached a high temperature in this blowing process, heat exchange is performed between this hot water and a heat medium such as fluorocarbons, and the heat medium becomes high temperature and high pressure due to this heat exchange. The system is designed to inject K into a turbine and drive a generator to generate electricity, thereby significantly reducing the burden of cooling the hot water circulating within the system, which was previously released into the atmosphere as waste heat. Coupled with the fact that the thermal energy that would have been released in
It is said that effects such as being able to significantly reduce the manufacturing cost of granulated slag can be obtained.

唆するところがない。(Problems with the prior art) However, the above-mentioned prior art utilizes the retained energy of hot water, which was conventionally released into the atmosphere as waste heat, by using it as a heat medium such as fluorocarbons to drive a fluorocarbon turbine. It is possible to recover it as electricity sb, and if this is implemented, it will contribute to energy conservation. However, it discloses the principle theory that is very important6, and there is no gap in terms of practical configuration and practical operation, especially when this method is applied to granulated slag processing equipment such as a full blast furnace. There is no suggestion whatsoever regarding the following points.

デアを実施に移すことはきわめて困雌である。For this reason, even if the above-mentioned conventional technology is simply applied to the processing equipment, heat exchange with fluorocarbons or the like as a heat medium cannot be performed uniformly, making it impossible to use the equipment as a power source for a turbine. Furthermore, as a problem, it is not desirable to completely remove the dust contained in the cooling water pressure of the granulated slag with the device shown in the earlier application publication, and unless the above two problems are technically solved, It is extremely difficult to implement the ideas proposed by the prior art.

。(Means for Achieving the Object) As a means for achieving the above object, the present invention provides an apparatus for quenching molten slag discharged from a blast furnace with water to granulate it. CFCs are generated by taking hot water from the middle of the hot water pipeline until it is cooled in a cooling tower, installing a receiving storage tank to store the hot water, and introducing the hot water that is continuously taken out from the receiving storage tank. In a granulated slag waste heat power generation system equipped with a power generation turbine driven by steam, the flow rate of cooling water supplied to the blowing device can be adjusted or adjusted in advance according to the amount of molten slag from the blast furnace. The main feature is that a cooling water regulating valve that can change the flow rate according to the determined molten slag discharge pattern is installed in the cooling water pipe that circulates and supplies the blowing equipment.
Or, for each blowing device of a granulated slag treatment facility equipped with two or more blowing devices that operate alternately in response to the discharge of molten slag, install a cooling water VJ control valve and a flow thrust adjustment valve for each blowing device. The system is installed in each of the cooling water water pipes that branch to the blast furnace, and supplies cooling water only to the blowing equipment in operation. The configuration is linked to the selection of the manufacturing equipment 2 and the discharge amount or discharge pattern of molten slag.

The slag is removed separately as product slag, while the filtered hot water is directed to receiving tank/2. The flow rate of hot water introduced into the receiving tank/2 varies and is intermittent. The hot water pump is driven based on a flow basin that is pre-adjusted to provide an average hot water flow rate by integrating the temporal change in the amount of hot water. The cooling water supplied to the fluorocarbon heat exchanger/3 and subjected to heat exchange is returned to the front of the thickener 6 through the cooling water return pipe 2g.

である。In addition, if there is no other heat source for factory waste heat, such as surplus steam, the surplus steam is introduced into the 2-g pipe as shown in the figure, and is received by the receiving water tank/! It is extremely economical to have a device that can be introduced into the system. In this case, in order to prevent the hot water from boiling inside the receiving needle IA/2, a device is installed to detect the temperature of the hot water in the storage tank and adjust the control valve 26 provided at the inlet of the exhaust heat source accordingly. It is desirable to do so. By providing the above-mentioned receiving storage @/2, the intermittently generated hot water can be continuously used as a purified heating fluid to generate electricity, and there is also other surplus steam. In some cases, this can also be effectively used as a power generating capacity source.

6. θθθ1 (Effects of the Invention) The device of the present invention is constructed as described above, and includes a receiving storage tank for storing hot water discharged from the dewatering equipment and a cooling water regulating valve that supplies an appropriate amount of cooling water to the blowing equipment. Alternatively, for equipment equipped with two or more blowing devices, in addition to providing the above-mentioned receiving storage tank, a cooling water regulating valve may be installed in the middle of the water pipe that supplies cooling water to each blowing device to control the pressure during operation. Since the device is designed to supply an appropriate amount of cooling water only to the blowing equipment, the temperature rise of the cooling water is completely uniformized, and thermal energy is stably exchanged with the heat medium, thereby eliminating intermittent problems. It becomes possible to continuously generate electricity in a stable state using a supplied heat source, and it exhibits excellent effects that could not be expected with conventional devices.

１）項記載の水砕スラグ排熱利用発電装置。(1) In a device that quenches molten slag discharged from a blast furnace with water to granulate it, a receiving storage tank is provided to take out hot water after separating the quenched granulated slag and store the hot water, and a receiving storage tank is installed to continuously flow from the receiving storage tank. In a power generation system using granulated slag waste heat, which is equipped with a power generation turbine driven by fluorocarbon steam generated by introducing hot water extracted from The cooling water is circulated through the blowing equipment through a cooling water regulating valve that can adjust the flow rate according to the amount of molten slag or change the flow rate according to a predetermined molten slag discharge pattern. A power generation device that uses waste heat from granulated slag because it is installed in a cooling water pipe. (No. In a granulated slag treatment facility equipped with two or more blowing devices that operate alternately in response to the discharge of molten slag, a valve for switching cooling water and adjusting the flow rate shall be installed for each blowing device. A trap is installed in each of the cooling water water pipes that branch to the blowing equipment, and cooling water is supplied only to the blowing equipment in operation, and the amount of supplied cooling water can be adjusted by controlling the blowing water pipes when discharging molten slag from the furnace. Claim 4O(
The power generation device using granulated slag exhaust heat as described in item 1).
