Definitions
- the present invention relates to a circulating gas circulating system for a coke dry-type fire extinguishing system (herein, referred to as a CDQ).
- the present invention relates to a steam-driven CDQ circulating air blowing method and a system using the same.
- red hot coke is charged into the pre-chamber of the main body of the CDQ, lowered into the cooling chamber, and the inert gas, which is the cooling gas supplied to the cooling chamber, exchanges heat with the red hot coatas, and the high temperature where the heat of the red hot coatas is recovered
- the circulation gas is sent again to the cooling chamber by the circulation pro- cessor to circulate it. Steam obtained by heat exchange in the boiler is mainly sent to the generator and collected as electrical energy.
- a steam turbine using a part of steam generated in a poiler is used. I have. At the time of startup, steam for driving the steam turbine cannot be obtained, so the air is blown by an electric-driven small circulation pump driven by a separately provided small motor, and when a predetermined amount of steam is generated, the circulation turbine is driven by the steam turbine. And drive.
- the present invention simplifies the method and equipment for circulating CDQ that can be started up by a steam turbine driven circulating blower that is used in a steady lotus rotation without using an electrically driven small circulating pump at startup. It is to provide a generalized circulation ventilation system.
- the method for circulating and blowing a CDQ comprises: exchanging heat between an incandescent gas charged in a CDQ main body and an inert gas introduced from below the CDQ main body; Heat is recovered by the boiler, and the inert gas cooled by the sensible heat recovery of the pillars is again introduced into the CDQ body by the circulation blower and circulated.
- the drive source to be driven is steam, and when the CDQ is started up, steam is introduced from a separately provided steam supply source, and after the completion of CDQ startup, steam is introduced from the bypass pipe provided in the steam pipe from the boiler.
- the CDQ circulating air blowing system of the present invention exchanges heat between the glowing coke charged into the CDQ main body and the inert gas introduced from below the CDQ main body, and converts the inert gas after the heat exchange. Recovers sensible heat in the boiler and introduces the inert gas cooled by the boiler's sensible heat recovery into the main body of the CDQ again using a circulation system to circulate it.
- a steam supply pipe for supplying steam to a steam turbine for use with the steam pipe from the boiler, and a steam supply pipe for supplying steam from a separately provided steam supply source is connected to the steam pipe.
- FIG. 1 is a flowchart showing an example of the CDQ circulation ventilation system of the present invention.
- FIG. 2 is a graph showing the relationship between the temperature rise of the inert gas and time.
- FIG. 1 is a flowchart showing an example of the CDQ circulation ventilation system of the present invention.
- the upper part of the main body of the CDQ 1 in which a red-hot coater is charged and exchanges heat with an inert gas as a cooling gas for cooling is connected to the boiler 4 by an exhaust duct 3 having a dust remover 2.
- the boiler 4 is connected to the lower part of the CDQ main body 1 by circulation ducts 6 and 7 through a circulation program 5.
- the high-temperature inert gas heat-exchanged with the red hot coke in the CDQ main unit 1 is exhausted from the CDQ main unit 1, is introduced into the boiler 4 via the exhaust duct 2, and is cooled by the heat exchange.
- the circulation blower 5 forms an inert gas circulation path that is introduced into the CDQ main body 1 through the circulation ducts 6 and 7.
- a heat transfer tube 8 is provided in the boiler 4, and water is supplied to the heat transfer tube 8 from water supply pipes 10 and 11 connected to a tank 9 by a water supply pump 12.
- the water that has flowed into the heat transfer tubes 8 is discharged from the CDQ main unit 1 and heat-exchanged by the high-temperature inert gas introduced into the boiler 4 to become steam, and the steam is turned into steam tubes 13 connected to the heat transfer tubes 8.
- the steam is sent to the power generation facility 14 via the, and exits the power generation facility 14, is condensed by the condenser 15, and flows into the tank 9.
- the circulation blower 5 is driven by a steam turbine 16.
- the steam turbine 16 is driven by steam supplied through a bypass pipe 17 branched from the steam pipe 13.
- the steam pipe 13 is opened to another steam supply source 18 to supply steam to the steam turbine 16 that drives the circulation processor 5 when the CDQ body 1 is started up.
- a steam supply pipe 20 with a closing valve 19 is connected.
- the steam supply pipe 20 is connected to a switching valve 21 provided on the boiler 4 side of the steam pipe 13 and a shutoff valve 22 provided on the power generation equipment 14 side. Connect between.
- a radiation pipe 24 having a radiation valve 23 is connected to the steam pipe 13 between the switching valve 21 and the poiler 4 side in order to diffuse the steam.
- the low-pressure steam that has exited the steam turbine 16 that drives the circulation processor 5 is sent to a raw material drying device 26 by a low-pressure steam pipe 25 and used for drying the raw material, is cooled and becomes water, and the water is returned to the tank 9. .
- the operation of the CDQ of the present invention will be described.
- the switching valve 21 and the shutoff valve 22 of the steam pipe 13 are closed, and the emission valve 23 is opened.
- the on-off valve 19 of the steam supply pipe 20 is opened, the steam from the steam supply source 18 drives the steam turbine 16 through the steam supply pipe 20, the steam pipe 13, and the bypass pipe 17, and the steam turbine 16 is turned on.
- the low-pressure steam that has exited is cooled and converted into water and returned to the tank 9. Water introduced from the tank 9 to the heat transfer pipe 8 via the water pipes 10 and 11 becomes steam and diffused through the steam pipe 13. Dissipated from 24.
- the inert gas is sent to the CDQ main body 1 by driving the steam turbine 16 by supplying steam from the steam supply source 18 and rotating the circulation blower 5 to exchange heat with the red hot coater.
- the inert gas thus exhausted is discharged from the CDQ main unit 1, passes through the exhaust duct 3, is introduced into the poiler 4, is cooled by heat exchange, and is passed through the circulating ducts 6 and 7 by the circulating duct 5 to the CDQ main unit 1.
- Figure 2 is a graph showing the relationship between the temperature rise of the inert gas and time.
- the temperature of the inert gas rises, and the steam temperature also rises with time, as shown by the Darraf in Figure 2.
- the temperature of the inert gas reaches about 800 ° C
- the heat transfer tube 8 2003/008502 The temperature of the generated steam rises, and the amount of steam required for the steam turbine 16 and the power generation equipment 14 is generated.
- the switching valve 21 and the shutoff valve 22 of the steam pipe 13 are opened, the dissipation valve 23 is closed, and the on-off valve 19 of the steam supply pipe 20 is closed.
- the steam flows through the pipe 13 to the power generation equipment 14, and partly drives the steam turbine 16 through the pipe pipe 17, and rotates the circulation pump 5 to circulate the inert gas.
