Secondly, replacing cleaning equipment with different flow rates requires additional time and human resources, which increases the complexity and cost of the operation. In addition, due to the different specifications and parameters of different cleaning equipment, the cleaning effect may be different and unstable. Summary of the invention

[0026] Below, the exemplary embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments of the present invention, and it should be understood that the present invention is not limited to the exemplary embodiments described here.

[0027] like Figure 1 and Figure 2 As shown, a steam turbine condenser tube bundle cleaning device comprises: a liquid storage tank body 1, at least two superchargers 2 with different powers, and a liquid outlet pipe 5. The superchargers 2 each have a liquid inlet 21 and a liquid outlet 22, each of the liquid inlet 21 is connected to the liquid storage tank body 1, and each of the liquid outlet 22 is connected to the liquid outlet pipe 5. The liquid in the liquid storage tank body 1 is suitable for being pressurized by the supercharger 2 and then sent to the liquid outlet pipe 5.

[0028] It should be noted that the liquid in the liquid storage cabinet body 1 is generally a mixture of water and detergent. The booster 2 pressurizes the liquid in the liquid storage cabinet body 1 and sends it to the liquid outlet pipe 5, which is equivalent to increasing the flow rate in the liquid outlet pipe 5 through the booster 2.

[0029] When the present steam turbine condenser tube bundle cleaning device is actually used, water and detergent can be added to the liquid storage tank body 1 in advance. Then the liquid in the liquid storage tank body 1 enters from the liquid inlet 21 of the supercharger 2, and after being pressurized by the supercharger 2, enters the liquid outlet pipe 5 from the liquid outlet 22, and then the liquid outlet pipe 5 is connected to one end of the pipeline to be cleaned. Since at least two superchargers 2 with different powers are provided, the maximum value of the pressure in the liquid outlet pipe 5 is the sum of the pressure values ​​of all superchargers 2, and the minimum value of the pressure in the liquid outlet pipe 5 is the pressure value of the supercharger 2 with the smallest power, so the pressure value in the liquid outlet pipe 5 can be adjusted by the cooperation of these superchargers 2, that is, the flow rate output by the liquid outlet pipe 5 is adjustable. Then, when cleaning pipelines with different flow rates, there is no need to replace cleaning devices with different flow rates. The combination of superchargers 2 can meet the cleaning of pipelines with different flow rates, which can reduce the workload and save manpower and material resources.

[0030] The steam turbine condenser tube bundle cleaning device of this embodiment can make the maximum value of the pressure in the liquid outlet pipe the sum of the pressure values ​​of all the superchargers by setting at least two superchargers with different powers, and the minimum value of the pressure in the liquid outlet pipe is the pressure value of the supercharger with the smallest power, so that the pressure value in the liquid outlet pipe can be adjusted by the cooperation of these superchargers, that is, the flow rate in the liquid outlet pipe is adjustable. Therefore, when cleaning pipelines with different flow rates, there is no need to replace cleaning equipment with different flow rates. The cooperation between the above-mentioned superchargers can meet the needs, that is, pipelines with different flow rates can be cleaned, which can reduce the workload and save manpower and material resources.

[0031] For example, Figure 1 and Figure 2 As shown, the steam turbine condenser tube bundle cleaning device also includes a liquid return pipeline 3 and a filter 4. The liquid return pipeline 3 is connected to the liquid storage tank body 1, and the filter 4 is installed on the liquid return pipeline 3. The liquid return pipeline 3 is connected to the other end of the pipeline to be cleaned, so that a cleaning loop is formed, and because the filter 4 is installed on the liquid return pipeline 3, the liquid flowing into the liquid storage tank body 1 through the filter 4 is a liquid without impurities and can be reused, which can save costs and improve efficiency.

[0032] For example, Figure 1 and Figure 2 As shown, the connection between the liquid inlet 21 and the liquid storage cabinet body 1 is provided with a check valve 6, which is suitable for allowing the liquid in the liquid storage cabinet body 1 to flow into the liquid inlet 21 in one direction. The first check valve 6 can prevent the pressure in the liquid outlet pipe 5 from leaking from the unopened supercharger 2 when the supercharger 2 is not fully opened, thereby ensuring the flow rate in the liquid outlet pipe 5 during cleaning.

[0033] For example, Figure 1 and Figure 2 As shown, a one-way valve 2 7 is arranged at the connection point between the return liquid pipeline 3 and the liquid storage cabinet body 1, and the one-way valve 2 7 is suitable for allowing the liquid in the return liquid pipeline 3 to flow into the liquid storage cabinet body 1 in one direction. The one-way valve 2 7 can prevent the liquid in the liquid storage cabinet body 1 from flowing back when the pressure in the return liquid pipeline 3 is insufficient.

[0034] For example, Figure 1 and Figure 2 As shown, the steam turbine condenser tube bundle cleaning device also includes an inner circulation pipe 81 and a third one-way valve 82. The first end of the inner circulation pipe 81 is connected to the liquid outlet pipe 5, and the second end of the inner circulation pipe 81 is connected to the liquid storage tank body 1. The third one-way valve 82 is arranged at the connection between the inner circulation pipe 81 and the liquid storage tank body 1, and the third one-way valve 82 is suitable for allowing the liquid in the inner circulation pipe 81 to flow into the liquid storage tank body 1 in one direction.

[0035] Specifically, Figure 1 and Figure 2 As shown, when the turbine condenser tube bundle cleaning device is working, the third one-way valve 82 is opened, and the liquid in the liquid storage tank body 1 can pass through the third one-way valve 82, the internal circulation pipe 81, the supercharger 2, and then return to the liquid storage tank body 1 in sequence, thus completing the internal circulation of the liquid in the liquid storage tank body 1, so that the detergent and water can be fully mixed, so that the cleaning effect is better.

[0036] For example, Figure 1 and Figure 2 As shown, a heating device 100 is arranged in the liquid storage cabinet body 1. The heating device 100 can heat the liquid in the liquid storage cabinet body 1, thereby preventing the liquid from freezing when the temperature is too low.

[0037] For example, Figure 1 and Figure 2 As shown, the liquid outlet pipe 5 is also provided with a pressure gauge 9. Through the provided pressure gauge 9, the liquid outlet pipe pressure of the liquid outlet pipe 5 can be monitored, so that the pressure of the two different boosters 2 can be easily controlled, and then the pressure value in the liquid outlet pipe 5 can be adjusted, that is, the output flow of the liquid outlet pipe 5 can be adjusted.

[0038] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
