Description

[0002] In the prior art, the heat energy not used in the coking process is converted into electric energy by the thermal power generation system to achieve the purpose of energy saving and environmental protection. Specifically, in the box type coking process, air is sucked into the inside of the coking box and mixed with the raw coal gas separated from the "coal brick" to burn. The heat generated by the burning is partly used for the dry distillation of the "coal brick", and the other part will form high-temperature flue gas with a temperature of about 1100℃. The high-temperature flue gas enters the dry quenching boiler of the thermal power generation system through the flue, exchanges heat with the deoxygenated water of the dry quenching boiler, and the deoxygenated water absorbs part of the heat of the high-temperature flue gas to become steam with certain quality, and the high-temperature flue gas loses part of the heat to become low-temperature flue gas.

The coke oven chamber cover 122 is used to seal the top opening, and the tray 123 is used to seal the bottom opening so that the coal briquettes 126 are located in the carbonization chamber 124. The tray 123 is provided with a smoke exhaust hole 125 communicating with the carbonization chamber 124, and the smoke exhaust hole 125 communicates with the smoke inlet channel 110.

[0042] During the coking process, air is drawn into the carbonization chamber 124 through air introduction holes provided on the side wall of the coke oven chamber 121 shell, and is mixed with the raw coal gas generated by the "coal bricks" to burn. Part of the heat generated by the burning is used for dry distillation of the "coal bricks", and the remaining heat is carried by the flue gas through the smoke exhaust hole 125 into the smoke inlet channel 110, and finally into the heating chamber to exchange heat with the heat exchange pipes 230. The plurality of coke oven assemblies 120 simultaneously exhaust high-temperature flue gas into the heating chamber, so that the heating chamber can obtain stable high-temperature flue gas to stably heat the heat exchange pipes 230.

[0043] In the embodiment of the present application, as shown in Figure 1 The smoke inlet channel 110 comprises a first flue 111 and a second flue 112. The inlet of the first flue 111 communicates with the smoke exhaust hole 125. The second flue 112 has a plurality of first smoke inlets 113 and a plurality of first smoke outlets 114. The first smoke inlets 113 communicate with the outlets of the first flues 111 one by one, and the first smoke outlets 114 communicate with the flue gas inlets 210 one by one. Since there are a plurality of coke oven assemblies 120, each of which has a corresponding smoke exhaust hole 125, the smoke inlet channel has a plurality of first flues 111, which communicate with the corresponding smoke exhaust holes 125. The flue gas exhausted by the smoke exhaust hole 125 enters the second flue 112 through the corresponding first flue 111, and the high-temperature flue gas generated by the plurality of coke oven assemblies 120 converges in the second flue 112 and enters the corresponding dry quenching boiler 200 through the first smoke outlet 114 to exchange heat with the corresponding heat exchange pipes 230.

[0044] In the embodiment of the present application, a first gate valve (not shown in the figure) is arranged between the inlet of the first flue 111 and the smoke exhaust hole 125, and a second gate valve (not shown in the figure) is arranged between the first smoke outlet 114 and the flue gas inlet 210. By controlling the opening degree of the first gate valve, the flow of high-temperature flue gas entering the second flue 112 from the first flue 111 can be controlled, and by controlling the opening degree of the second gate valve, the flow of high-temperature flue gas entering the corresponding heating chamber from the second flue 112 can be controlled. That is, by controlling the opening degrees of the first gate valve and the second gate valve, the flow of high-temperature flue gas can be adjusted.

[0045] In the embodiments of the present application, as shown in Figure 1 The smoke outlet passage 310 includes a third flue 311 and a fourth flue 312. The third flue 311 has an inlet communicating with the smoke outlet 220. The fourth flue 312 has a second smoke outlet 313 and a plurality of second smoke inlets 314, the second smoke inlets 314 communicating with the outlets of the third flue 311 one by one, and the second smoke outlet 313 communicating with the chimney 300. The heating chamber can have a plurality of smoke outlets 220, and the plurality of third flues 311 communicate with the corresponding smoke outlets 220. The high-temperature flue gas is converted into low-temperature flue gas after heat exchange with the heat exchange pipes 230 in the heating chamber, and the low-temperature flue gas enters the fourth flue 312 through the corresponding third flue 311. The low-temperature flue gas discharged from the plurality of dry quenching boilers 200 converges in the fourth flue 312 and enters the chimney 300 through the second smoke outlet 313.

[0046] In the embodiments of the present application, a third gate valve (not shown in the figure) is arranged between the inlet of the third flue 311 and the smoke outlet 220, and a fourth gate valve (not shown in the figure) is arranged between the second smoke outlet 313 and the chimney 300. By controlling the opening degree of the third gate valve, the flow of the low-temperature flue gas in the third flue 311 entering the fourth flue 312 can be controlled, and by controlling the opening degree of the fourth gate valve, the flow of the low-temperature flue gas in the fourth flue 312 entering the chimney 300 can be controlled. That is, by controlling the opening degrees of the third gate valve and the fourth gate valve, the flow of the low-temperature flue gas can be adjusted.

[0047] In the embodiments of the present application, as shown in Figure 1 The third flue 311 is provided with a fan 315. The low-temperature flue gas in the third flue 311 can be accelerated to enter the fourth flue 312 by the fan 315, so as to improve the discharge speed of the low-temperature flue gas.

[0048] In the embodiments of the present application, the steam turbine power generation assembly 500 includes a steam turbine (not shown in the figure) and a generator (not shown in the figure). The steam inlet of the steam turbine communicates with the outlets of the plurality of heat exchange pipes 230, the steam outlet of the steam turbine communicates with the water inlet 420 of the water supply assembly 400 through a condenser, and the generator is connected with the steam turbine. The water supply assembly 400 inputs circulating water to the heat exchange pipes 230, and the circulating water in the heat exchange pipes 230 is heated to become high-temperature steam entering the steam inlet of the steam turbine, and the high-temperature steam does work in the steam turbine. Since the generator is connected with the steam turbine, the steam turbine drives the generator to generate electricity. The high-temperature steam is converted into exhaust steam after doing work, and the exhaust steam returns to the water supply assembly 400 through the condenser.

[0049] In the embodiment of the present application, the first port of the condenser is in communication with the steam outlet of the steam turbine, the second port of the condenser is in communication with the water inlet 420 of the water supply assembly 400, the third port of the condenser is in communication with the cooling water supply pipe, and the fourth port of the condenser is in communication with the cooling water return pipe. The cooling water enters the condenser from the cooling water supply pipe to exchange heat with the exhaust steam, and the cooling water after heat exchange flows out from the cooling water return pipe to take away the heat of the exhaust steam. The circulating water after heat exchange with the exhaust steam in the condenser returns to the water supply assembly 400 from the second port of the condenser, i.e. the condensed water returns to the water supply assembly 400 from the second port of the condenser.

[0050] In the embodiment of the present application, the water supply assembly 400 comprises a water supply tank (not shown in the figure), which has a water inlet 420 and a plurality of water outlets 410. The water outlets 410 are in one-to-one correspondence with the inlets of the plurality of heat exchange pipes 230, and the water inlet 420 is in communication with the outlet of the steam turbine generator assembly 500. The water supply tank stores a large amount of circulating water inside. When the thermal power generation system is working, the circulating water enters the corresponding heat exchange pipe 230 from the plurality of water outlets 410 of the water supply tank to start the heat exchange cycle, and then passes through the steam turbine and the condenser in turn, and finally returns to the water supply tank.

[0051] In the embodiment of the present application, the water supply tank is in communication with the desalted water pipeline of the plant. The water supply tank can be a desalted water tank, i.e. the water supply tank stores desalted water inside. During the operation of the thermal power generation system, the loss of circulating water will inevitably occur. The desalted water is supplied to the water supply tank through the desalted water pipeline of the plant to make up for the loss of circulating water during the operation of the thermal power generation system. It should be noted that the circulating water is desalted water. Since the circulating water does not contain various salt ions, scale will not be formed during the circulation of the circulating water, thereby prolonging the service life of the thermal power generation system.

[0052] In the embodiment of the present application, the water supply assembly 400 further comprises a deaerator (not shown in the figure), which is provided with a low-pressure steam inlet for receiving external low-pressure steam. The inlet of the deaerator is in communication with the water outlet 410 of the water supply tank through a water supply pump, and the outlet of the deaerator is in communication with the inlet of the heat exchange pipe 230. When the oxygen in the circulating water is dissolved, on the one hand, the metal in contact with the circulating water will be corroded; on the other hand, the presence of oxygen in the circulating water will increase the thermal resistance of heat transfer, thereby reducing the heat exchange efficiency of the flue gas heat recovery system. Therefore, by removing the oxygen in the circulating water through the deaerator, on the one hand, the corrosion of the heat exchange pipe 230 can be avoided, and on the other hand, the heat exchange efficiency of the flue gas heat recovery system can be improved. In addition, the deaerator can also serve as a heater to assist in heating the circulating water. Since the water supply pump is arranged between the inlet of the deaerator and the water outlet of the water supply tank, the water supply pump can transport the circulating water stored in the water supply tank to the deaerator.

[0053] The above merely describes preferred embodiments of the present application, and is not intended to limit the scope of protection of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
