Optionally, referring to fig. 1, the steam supplementing pipeline 100 is configured with a sintering waste heat boiler, and a steam outlet of the sintering waste heat boiler is communicated with a steam inlet of the steam supplementing pipeline 100. The technical scheme is compatible with the existing sintering waste heat boiler, and can also utilize the superheated steam of water produced by the newly-built sintering waste heat power generation system after the sintering waste heat boiler is built.
Because the low-pressure steam pressure and the temperature generated by the sintering waste heat boiler are low, the low-pressure steam can not be sent into a steam pipe network in a factory, and the utilization rate is low. The steam introduced into the seawater desalination device adopts low-pressure steam generated by a sintering waste heat boiler, and the utilization rate of the low-pressure steam can be increased after the low-pressure steam is sent into the seawater desalination device.

Through the temperature and pressure reducing device 400, the air pressure and temperature of the steam before entering the negative pressure steam expansion cylinder 200 are controlled, the defect that the volume of the cylinder cavity is too large due to large variation of the front and rear air pressure of the negative pressure steam expansion cylinder 200 is overcome, and a series of adverse factors caused by too large specification of the negative pressure steam expansion cylinder 200 are overcome.
In the matching of the temperature and pressure reducing device 400 and the negative pressure steam expansion cylinder 200, it should be understood that the temperature and pressure reducing device 400 can reduce the pressure of the low pressure steam from the pipe network to 0.1MPa at maximum and cannot reduce the pressure to a negative pressure state, and then the low pressure steam needs to be expanded and reduced again by the negative pressure steam expansion mixing cylinder to be fully mixed with the steam turbine exhaust.
Optionally, the desuperheating pressure reducing device 400 includes a reduced pressure conduit 410 and a desuperheating water conduit 420. The pressure reducing pipeline 410 is provided with a first pressure reducing valve group, a steam inlet of the pressure reducing pipeline 410 is communicated with a steam outlet of the steam supplementing pipeline 100, and a steam outlet of the pressure reducing pipeline 410 is communicated with a steam inlet of the negative pressure steam expansion cylinder 200. The water outlet of the temperature reduction water pipe 420 is communicated with the lumen of the pressure reduction pipeline 410.

Alternatively, the steam outlet of the negative pressure steam expansion cylinder 200 is composed of a plurality of steam injection ports. The negative pressure steam expansion cylinder 200 is made by using the principle of adiabatic isothermal expansion, and the steam outlet is formed by a plurality of steam nozzles to form a dense small hole form. The low-pressure steam enters the negative-pressure steam expansion cylinder 200 after being subjected to primary pressure reduction, is subjected to adiabatic expansion, is uniformly sprayed into a steam exhaust pipeline 21 of the steam turbine through dense small holes formed in the cylinder, and is uniformly mixed with the steam exhaust of the steam turbine.
On one hand, the negative pressure steam expansion cylinder 200 further reduces the pressure of the low pressure steam from the pipe network so as to reduce the pressure difference and the steam flow rate and reduce the vibration of the equipment; on the other hand, the two kinds of steam with different parameters are uniformly mixed and then enter the seawater desalination device, so that the temperature difference and the thermal stress of the device are reduced, the stable operation of the seawater desalination device is protected, and the device has outstanding advantages.
Optionally, the water inlet of the desuperheating water pipe 420 is communicated with the condensed water pump outlet of the steam exhaust device 20 of the steam turbine, and the related steam desuperheating is performed by using the condensed water as the desuperheating water.
Optionally, a temperature detection unit is configured at the steam inlet of the seawater desalination device, and the temperature detection unit is used for assisting the operation of the temperature reduction water pipe 420. Because the dryness of the steam discharged by the steam turbine is less than 100 percent, part of useless wet steam exists; and after low-pressure superheated steam is sprayed into the exhaust steam of the steam turbine, wet steam in the exhaust steam is vaporized again, latent heat of vaporization is absorbed, and the temperature is reduced. In the technical scheme, the steam entering the seawater desalination device does not need to be subjected to temperature control, and when the steam entering the seawater desalination device is over-temperature, desuperheating water is sprayed.
Therefore, in normal conditions, the desuperheating water is not sprayed, and the desuperheating and depressurizing device 400 is only put into a depressurizing valve in the depressurizing pipeline 410 to operate and relies on the wet steam in the exhaust steam of the steam turbine to desuperheat; if the temperature of the inlet of the seawater desalination device rises, the desuperheating water is added.
In the technical scheme, the vacuum degree of the exhaust steam of the steam turbine is controlled by the condensation temperature of the last effect of the seawater desalination device. The larger the steam inlet quantity of the seawater desalination device is, the lower the corresponding vacuum degree is. Under normal conditions, the newly added heat supplementing device does not perform pressure control, and when the vacuum degree of the seawater desalination device deviates from a design value, the amount of injected low-pressure steam can be reduced to perform vacuum degree regulation and protection.
Optionally, a pneumatic steam flow regulating valve and a pore plate flowmeter are provided, the steam outlet of the steam supplementing pipeline 100 is communicated with the steam inlet of the negative pressure steam expansion cylinder 200 through the pneumatic steam flow regulating valve, and the pore plate flowmeter is used for measuring the steam inlet of the negative pressure steam expansion cylinder 200.

Moreover, the system is provided with low-pressure steam flow, temperature and pressure detection; detecting the temperature and the pressure of the steam after temperature and pressure reduction; detecting the flow, temperature and pressure of the temperature-reducing water; and detecting mixed steam pressure and temperature, and acquiring detection data by using related detection units, thereby being beneficial to monitoring the operation condition of the system.
And moreover, a receiving stop valve is arranged on the system, so that the seawater desalination device can be guaranteed to be vacuumized and steam-tight when being started, and can be effectively separated from the CCPP during maintenance.
Supplementary note, in the seawater desalination concurrent heating system 10 of this technical solution, the diameter of the negative pressure steam expansion cylinder 200 is much smaller than the diameter of the cross section of the steam exhaust pipeline 21, and the steam turbine exhaust steam enters the steam inlet branch pipeline 30 of the seawater desalination apparatus through the cross section of the steam exhaust pipeline 21. Because the diameter of the transverse section of the steam exhaust pipeline 21 is larger, one steam exhaust pipeline 21 shown in figure 2 is provided with two steam inlet branch pipelines of the seawater desalination device, the steam flow of each side is only half of the outlet pipeline of the steam exhaust device, and the flow speed is lower; the flow area of the outlet pipeline of the steam exhaust device is 2 times of the flow area of the outlet pipeline of the steam exhaust device before the negative pressure steam expansion cylinder 200 is installed, and the concurrent flow area of the negative pressure steam expansion cylinder 200 is 1.9 times of the flow area of the outlet pipeline of the steam exhaust device, so the installation position is proper.
In the technical scheme, it is understood that the amount of steam entering the seawater desalination device is increased, the condensation temperature of the final sea fresh effect is increased, the back pressure of the steam turbine is correspondingly increased, and the steam exhaust temperature of the steam turbine is increased. The exhaust pressure of the steam turbine is improved, and the generated energy of the steam turbine is correspondingly reduced. It is therefore not desirable to increase both the power generation and the sea fresh water yield simultaneously.
