[0027] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.
[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited to the specific embodiments disclosed below.
[0029] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor does it mean that the embodiment is mutually exclusive or selective with other embodiments.
[0030] Thirdly, the present application is described in detail in combination with the schematic diagram. In the detailed description of the embodiments of the present application, the cross-sectional view of the device structure is partially enlarged without the general proportion for the convenience of illustration, and the schematic diagram is only an example which should not limit the scope of protection of the present application. In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual production.
[0031] Embodiment 1, referring to Figures 1-3, is the first embodiment of the present application, which provides an intermediate cooling system control device. The device includes an intermediate cooling unit 100, an air inlet unit 200, and an air suction unit 300.
[0032] The air inlet unit 200 is arranged in the intermediate cooling unit 100. The air suction unit 300 includes a mounting bracket 302 arranged on the air inlet unit 200, a wind wheel 301 rotatably arranged on the mounting bracket 302, a bearing assembly 304 arranged on the mounting bracket 302, a connecting assembly 303 arranged on the bearing assembly 304 for supporting the wind wheel 301, and a driving motor 305 arranged on the mounting bracket 302 for driving the wind wheel 301 to rotate. The air inlet unit 200 guides the hot gas generated by the steam turbine into the interior of the intermediate cooling unit 100 through the air inlet shell 201 arranged on the shell. The air inlet shell 201 helps to evenly distribute the incoming airflow, ensuring that the airflow can efficiently pass through the heat exchange assembly 102 for heat exchange. The adjustment assembly 203 in the air inlet unit 200 allows the operator to adjust the airflow into the heat exchange assembly 102 as needed, thereby controlling the cooling speed and efficiency. By adjusting the adjustment plate 203a and the adjustment part 203b in the adjustment assembly 203, the flow direction and speed of the airflow can be adjusted to optimize the heat exchange effect. The air inlet unit 200 provides a mounting base for the air suction unit 300.
[0033] The intermediate cooling unit 100 includes a shell 101, a heat exchange assembly 102 arranged in the shell 101 and located at the output end of the air suction unit 300, an air inlet assembly 103 arranged on the shell 101 and having an output end located at the air inlet unit 200, and an air outlet assembly 104 arranged on the shell 101 and located at the heat exchange assembly 102. The heat exchange assembly 102 inside the intermediate cooling unit 100 is responsible for heat exchange with high-temperature flue gas, and transfers heat to the cooling medium through indirect contact, achieving the cooling process without directly using water resources. Through the design of the air inlet assembly 03 and the air outlet assembly 104, the intermediate cooling unit 100 can orderly organize the airflow, ensuring that the high-temperature flue gas uniformly passes through the heat exchange assembly 102, thereby improving the cooling efficiency.
[0034] In use, the hot gas generated by the steam turbine enters the air inlet assembly 103 into the air inlet shell 201, and is guided and separated by the air inlet shell 201. The driving motor 305 drives the wind wheel 301 to rotate, so that the wind wheel 301 sucks in the hot gas and then delivers it to the heat exchange assembly 102 for indirect cooling. The excess hot gas is discharged through the air outlet assembly 104, and the wind wheel 301 suspended at the bottom reduces the friction and support force of the driving motor 305, so that the wind wheel 301 moves more stably. The wind wheel 301 is supported by the bearing assembly 304 and the connecting assembly 303.
[0035] Embodiment 2, referring to FIGS. 1-5, is a second embodiment of the present application. The difference between this embodiment and the first embodiment is that the air inlet unit 200 includes an air inlet shell 201 arranged on the shell 101, a wind tunnel plate 202 arranged in the air inlet shell 201, and an adjusting assembly 203 arranged on the air inlet shell 201 below the wind tunnel plate 202.
[0036] Further, the adjusting assembly 203 includes an adjusting plate 203a rotatably arranged on the air inlet shell 201, and an adjusting part 203b arranged on the air inlet shell 201 for driving the adjusting plate 203a to rotate. The design of the multi-stage adjusting plate 203a allows more detailed air flow distribution, reduces energy waste, and improves overall energy efficiency.
[0037] In use, the wind tunnel plate 202 can make the hot gas entering the shell 101 at the air inlet assembly 103 more uniform, and then the hot gas is uniformly separated by the multiple adjusting plates 203a. The adjusting part 203b can drive the adjusting plate 203a to rotate, so that the inclination angle of the adjusting plate 203a can be adjusted. According to the different inclination angles, the air inlet amount can be controlled, so that the speed of indirect cooling can be controlled. The adjusting part 203b is a plurality of gear structures, and the plurality of gears are arranged on the plurality of adjusting plates 203a respectively. The rack is driven to move by the telescopic cylinder, and the rack is engaged with the gear to drive, so that the plurality of adjusting plates 203a can be flipped at the same time.
[0038] The wind tunnel plate 202 realizes uniform guiding and separation of air inlet, improving the heat exchange efficiency. The adjusting assembly 203 allows dynamic adjustment of the air inlet amount according to actual needs through the cooperation of the adjusting plate 203a and the adjusting part 203b, improving the flexibility and adaptability of the system.
[0039] The remaining structure is the same as that of embodiment 1.
[0040] Embodiment 3, referring to FIG. 1-5, is the third embodiment of the present application, which is different from the second embodiment in that: the mounting rack 302 is arranged on the air inlet shell 201; the wind wheel 301 comprises a mounting seat 301a rotatably arranged in the mounting rack 302, a rotating seat 301b, and blades 301c arranged on the mounting seat 301a and the rotating seat 301b; and the output end of the driving motor 305 is connected with the rotating seat 301b. The mounting seat 301a is provided with a mounting groove one 301a-1, and the rotating seat 301b is provided with a mounting groove two 301b-1; the two ends of the blades 301c are respectively embedded in the mounting groove one 301a-1 and the mounting groove two 301b-1; the mounting seat 301a and the rotating seat 301b are provided with a fixing assembly 306 for connection; the wind wheel 301 is driven by the driving motor 305 to generate power when rotating, promoting the circulation of hot air flow inside the intercooling system. The rotation of the wind wheel 301 helps the sufficient contact between the hot air flow and the heat exchange assembly 102, thereby improving the efficiency of heat exchange.
[0041] The fixing assembly 306 comprises a fixing column 306a arranged on the rotating seat 301b, a threaded part 306b arranged on the fixing column 306a, a connecting frame 306c arranged in the mounting seat 301a and in sliding connection with the threaded part 306b, and a threaded sleeve 306d in threaded connection with the threaded part 306b and in abutment with the connecting frame 306c; the blades 301c are arranged in plurality and inserted into the mounting groove one 301a-1 and the mounting groove two 301b-1 and supported by the mounting groove one 301a-1 and the mounting groove two 301b-1; the blades 301c of the wind wheel 301 are supported by the mounting groove one 301a-1 and the mounting groove two 301b-1, simplifying the installation process. The design of the fixing assembly 306 allows quick replacement of damaged blades 301c, improving the maintenance efficiency; since the weight of the wind wheel 301 is supported by the connecting assembly 303 and the bearing assembly 304, the dependence on the power of the driving motor 305 is reduced, thereby reducing energy consumption and being able to adapt to more motor models, thus reducing the cost.
[0042] The connecting frame 306c is sleeved on the threaded part 306b and supported by the fixing column 306a, the threaded sleeve 306d is screwed into the threaded part 306b, and the threaded sleeve 306d is in abutment with the connecting frame 306c, so that the mounting seat 301a presses the blades 301c on the rotating seat 301b, for fixation and connection.
[0043] Further, the bearing assembly 304 comprises a bearing seat 304a arranged on the mounting rack 302, two fixing sleeves 304b arranged on the bearing seat 304a, and a roller 304c arranged between the two fixing sleeves 304b and in sliding connection with the bearing seat 304a.
[0044] The connecting assembly 303 comprises a connecting sleeve 303a arranged on the mounting seat 301a and in sliding connection with the bearing seat 304a and the roller 304c, a pressing ring 303b arranged on the connecting sleeve 303a and in sliding connection with the roller 304c, a connecting block 303c arranged on the connecting sleeve 303a and in clamping connection with the mounting seat 301a, and a connecting bolt 303d arranged on the mounting seat 301a and in threaded connection with the connecting block 303c. The mounting seat 301a is provided with a connecting groove 301a-2 for embedding the connecting block 303c, and a bolt hole 301a-3 for embedding the connecting bolt 303d. The connecting assembly 303 is directly connected with the mounting seat 301a of the wind wheel 301, supports the weight of the wind wheel 301, and ensures the stability and balance of the wind wheel 301 during rotation. Through the design of the connecting assembly 303, the weight and rotating force of the wind wheel 301 do not directly act on the shaft of the driving motor 305, thereby reducing friction and wear, and prolonging the service life of the driving motor 305 and the wind wheel 301
[0045] The roller 304c is guided by the fixing sleeve 304b and installed and supported by the bearing seat 304a. The connecting sleeve 303a passes through the inside of the fixing sleeve 304b and is in sliding connection with the roller 304c. The pressing ring 303b is pressed on the roller 304c. The connecting block 303c is inserted into the connecting groove 301a-2 on the wind wheel 301. The connecting bolt 303d is inserted into the bolt hole 301a-3 and screwed into the connecting block 303c. Thus, the connection between the mounting seat 301a and the connecting sleeve 303a is completed. The installation and connection can be facilitated, and if one part is damaged, it can be easily removed and replaced.
[0046] The wind wheel 301 is supported by the bearing assembly 304 and the connecting assembly 303, which solves the problem of motor shaft deviation caused by the weight of the fan supported by the motor shaft in the prior art, thereby improving the stability and reliability of the fan. Since the movement of the wind wheel 301 is more stable, the wear caused by friction and supporting force is reduced, thereby prolonging the service life of the equipment and reducing the maintenance requirements.
[0047] In use, the mounting frame 302 supports the bearing assembly 304, the connecting assembly 303 is supported by the bearing assembly 304, the connecting assembly 303 is fixed to the mounting base 301a, the rotating base 301b is in a suspended state, so as to reduce the friction between the wind wheel 301 and the mounting frame 302, the weight of the wind wheel 301 is supported by the connecting assembly 303 and the bearing assembly 304, the rotating base 301b can be driven to rotate by the driving motor 305, the rotating base 301b drives the fixed assembly 306 to rotate, the fixed assembly 306 drives the mounting base 301a to rotate, so that the blade 301c rotates, and since the blade 301c has an arc-shaped structure and an inverted bevel structure on the inner side, the wind can be better sucked in and then sprayed out from the side, the hot gas is sprayed into the heat exchange assembly 102 to perform heat exchange, so as to perform indirect cooling.
