Description

Technical Field

[0001] The utility model relates to the technical field of power generation devices, in particular to a steam turbine condensate recovery device. Background Art

[0002] Steam turbine condensate is the water produced when steam cools and condenses in the condenser during turbine operation. This condensate is primarily formed by cooling steam discharged from the turbine. The condensate recovery system is responsible for collecting this water for reuse or treatment.

[0003] Existing patent CN220250717U discloses a condensate recovery device for steam-driven turbine power generation, which includes an upper tank body and a lower tank body. The upper tank body surface and the lower tank body surface are connected by bolts. An exhaust mechanism and a filtering mechanism are provided above the upper tank body, and the filtering mechanism is located above the exhaust mechanism; the exhaust mechanism includes a rotating part and an exhaust part; the rotating part is located on the left side of the exhaust part.

[0004] In order to solve the problem that steam cannot be quickly sucked into the shell, resulting in low efficiency in condensate recovery, this patent uses an exhaust mechanism to speed up the efficiency of steam transportation to the lower tank and the upper through-hole, thereby speeding up the efficiency of condensate recovery operations.

[0005] However, in actual use, there are still the following deficiencies, for example: when the cleaning brush is brushing the filter back and forth, if the cleaning brush is brushed to one side of the collection box, the impurities on the other side will gradually accumulate on the other side of the cleaning brush. In this case, the filter cannot effectively achieve a comprehensive cleaning effect, and the cleaning brush cannot take into account the impurities on both sides at the same time. As time goes by, these accumulated impurities may further clog the filter, resulting in a decrease in the filtering effect.

[0006] Therefore, the utility model provides a steam turbine condensate recovery device. Utility Model Content

[0007] The purpose of the utility model is to solve the shortcomings of the prior art and provide a steam turbine condensate recovery device.

[0008] To achieve the above-mentioned object, the present invention adopts the following technical solution: a steam turbine condensate recovery device, comprising a condensate recovery tank, a top end of the condensate recovery tank being fixedly connected to a pipe assembly, a top end of the pipe assembly being fixedly connected to a cleaning assembly, a top end of the cleaning assembly being fixedly connected to a pressure assembly, and an interior of the pipe assembly being fixedly connected to an air intake assembly;

[0009] The pipeline assembly includes a filter tube, the bottom end of the filter tube is fixedly connected to the condensate recovery tank, and the top end of the filter tube is installed with a top cover;

[0010] The cleaning component includes a motor and an air suction device, the driving end of the motor is fixedly connected to a fan, the inside of the filter tube is fixedly connected to a filter screen, the suction end of the air suction device is fixedly connected to a suction tube, and the outside of the driving end of the motor is fixedly connected to a cleaning brush.

[0011] As a preferred embodiment, the pressure assembly includes a telescopic column, the bottom end of the telescopic column is fixedly connected to the top end of the cleaning brush, and a pressure spring is sleeved on the outer side of the telescopic column.

[0012] The technical effects of adopting the above technical solution are:

[0013] The filter can be cleaned regularly to avoid the accumulation of impurities on the filter, and the impurities on the filter can be sucked into the suction device through the suction pipe, further ensuring the cleanliness of the filter and ensuring that the cleaning brush is in close contact with the filter, thereby improving cleaning efficiency.

[0014] As a preferred embodiment, the air intake assembly includes an air intake pipe, the outer side of the air intake pipe is installed on the filter pipe, and one end of the air intake pipe away from the filter pipe is fixedly connected to a one-way valve.

[0015] The technical effect of adopting the above technical solution is: it can ensure that during the cleaning process, external air will not flow back into the filter tube, thereby maintaining a negative pressure state inside the filter tube, which is conducive to the suction of impurities and the cleaning of the filter screen.

[0016] As a preferred embodiment, the bottom end of the cleaning brush contacts the top end of the filter screen.

[0017] The technical effect of adopting the above technical solution is to ensure that the cleaning brush can more effectively remove impurities attached to the surface of the filter when cleaning the filter, while avoiding damage to the filter.

[0018] As a preferred embodiment, the outer side of the motor is mounted on the top end of the top cover.

[0019] The technical effect of adopting the above technical solution is: facilitating the heat dissipation and maintenance of the motor, while reducing the space occupied by the motor in the interior of the pipeline assembly, making the overall structure more compact.

[0020] As a preferred embodiment, one end of the pressure spring is fixedly connected to the top cover, and the other end of the pressure spring is fixedly connected to the cleaning brush.

[0021] The technical effect of adopting the above technical solution is: through the elastic force of the pressure spring, it can be ensured that the cleaning brush applies appropriate contact pressure to the filter screen during the cleaning process, thereby improving the cleaning effect.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are:

[0023] The utility model provides a cleaning component and a pressure component structure. The gas first enters the filter pipe through the intake pipe and is ensured to flow in one direction by a one-way valve. The condensed water then flows into the recovery tank. At the same time, the filter screen undergoes preliminary filtration to intercept impurities to ensure water quality. The filtered water enters the tank body under the action of gravity. As impurities accumulate on the filter screen, the cleaning component is started, the motor rotates in the reverse direction to generate air flow, driving the cleaning brush to scrub the filter screen and remove impurities. The telescopic column and pressure spring ensure that the cleaning brush is close to the filter screen, and the impurities are then discharged through the suction device and the suction pipe. This design enables the cleaning brush to effectively scrub the impurities on the surface of the filter screen, ensuring the cleaning effect of the filter screen, thereby extending the service life of the filter screen and improving the filtration efficiency. In addition, the cleaning brush can automatically adjust its position according to the unevenness of the filter screen surface to ensure good contact between the cleaning brush and the filter screen, thereby effectively solving the problem of impurity accumulation on both sides of the filter screen and avoiding further accumulation and blockage of impurities, thereby ensuring the comprehensive cleaning of the filter screen.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a steam turbine condensate recovery device, comprising a condensate recovery tank 1, a pipe assembly 2 fixedly connected to the top of the condensate recovery tank 1, a cleaning assembly 3 fixedly connected to the top of the pipe assembly 2, a pressure assembly 4 fixedly connected to the top of the cleaning assembly 3, and an air intake assembly 5 fixedly connected to the interior of the pipe assembly 2;

[0036] The pipe assembly 2 includes a filter tube 21, the bottom end of which is fixedly connected to the condensate recovery tank 1, and a top cover 22 is installed on the top of the filter tube 21. The filter tube 21 is the core component of the entire device and is responsible for preliminary filtering of the incoming condensate. The bottom end is fixedly connected to the condensate recovery tank 1 to ensure that the condensate can smoothly enter the tank body for collection under the action of gravity. The top cover 22 installed on the top not only protects the interior of the filter system from external pollutants, but also provides a stable installation foundation for the motor 31 and other components.

[0037] The cleaning assembly 3 includes a motor 31 and an air suction device 34. The outer side of the motor 31 is mounted on the top of the top cover 22. The driving end of the motor 31 is fixedly connected to the fan 32. The interior of the filter tube 21 is fixedly connected to the filter screen 33. The suction end of the air suction device 34 is fixedly connected to the suction pipe 35. The outer side of the driving end of the motor 31 is fixedly connected to a cleaning brush 36. The bottom end of the cleaning brush 36 contacts the top end of the filter screen 33.

[0038] The motor 31 is the core of the cleaning component 3. It drives the fan 32 to generate a rotating airflow to clean the filter 33. The motor 31 is externally mounted on the top of the top cover 22 to ensure the stable operation of the motor 31. The fan 32 driven by the motor 31 generates an airflow through rotation, which can effectively draw in air through the filter 33, so that the filtered condensate enters the recovery tank. The filter 33 is responsible for intercepting impurities carried in the condensate to ensure the purity of the water flowing into the tank. The air suction device 34 draws airflow and impurities from the filter pipe 21 through the air suction pipe 35, so that the condensate filtering process is not affected by blockage. The cleaning brush 36 contacts the filter 33 and brushes back and forth with the rotation of the motor 31, thereby preventing impurities from accumulating on the surface of the filter 33 during the cleaning process. Secondly, the reverse rotation of the motor 31 blows the wind upward, further discharging the impurities on the filter 33 from the system.

[0039] In order to ensure that the outer side of the cleaning brush 36 can be attached to the filter screen 33 during the cleaning process, Figure 1 - Figure 3 As shown: in this solution, the pressure assembly 4 includes a telescopic column 41, the bottom end of the telescopic column 41 is fixedly connected to the top end of the cleaning brush 36, and a pressure spring 42 is sleeved on the outer side of the telescopic column 41, one end of the pressure spring 42 is fixedly connected to the top cover 22, and the other end of the pressure spring 42 is fixedly connected to the cleaning brush 36. The design of the telescopic column 41 can automatically adjust the position of the cleaning brush 36 according to the degree of unevenness of the surface of the filter 33, and the pressure spring 42 is designed to provide continuous pressure so that the cleaning brush 36 is always pressed tightly against the filter 33. One end of the spring is fixed to the top cover 22, and the length of the telescopic column 41 is automatically adjusted during the cleaning process through elastic action, thereby maintaining good contact between the cleaning brush 36 and the filter 33. This design can prevent the cleaning brush 36 from gradually losing contact with the filter 33 due to long-term use, thereby ensuring the continuity of cleaning efficiency;

[0040] The air intake assembly 5 includes an air intake pipe 51, the outer side of the air intake pipe 51 is installed on the filter tube 21, and a one-way valve 52 is fixedly connected to the end of the air intake pipe 51 away from the filter tube 21. The air intake assembly 5 introduces external air into the filter tube 21 through the air intake pipe 51, and the outer side of the air intake pipe 51 is firmly installed on the filter tube 21 to ensure that the airflow can smoothly enter the filter system. This air intake design ensures the stability of the airflow in the filter system and provides sufficient airflow support for the cleaning assembly 3 and the condensate recovery process. In order to prevent backflow and reverse airflow from affecting the filtering effect, a one-way valve 52 is installed on the end of the air intake pipe 51 away from the filter tube 21. The one-way valve 52 ensures that the airflow can only enter the filter tube 21 in one direction, preventing pollutants from flowing into the system during cleaning.

[0041] Working principle:

[0042] like Figure 1- Figure 4 As shown:

[0043] During use: first, the gas is introduced into the filter tube 21 through the air inlet pipe 51, and then the one-way valve 52 is driven to ensure that the airflow enters the filter tube 21 in one direction. Then, the condensed water flows into the condensed water recovery tank 1 through the pipe component 2, and then the filter screen 33 in the filter tube 21 is driven for preliminary filtration. The filter screen 33 intercepts impurities in the condensed water to ensure that the water quality flowing into the tank body is pure. The filtered condensed water smoothly enters the tank body for collection under the action of gravity. As the condensed water continues to flow in, impurities gradually accumulate on the filter screen 33. At this time, the cleaning component 3 begins to work, the motor 31 is started in reverse, and the fan 32 at the drive end generates a rotating airflow. , and then drives the cleaning brush 36 to scrub back and forth. The cleaning brush 36 contacts the filter screen 33 and effectively scrubs the impurities on the surface of the filter screen 33 through the rotational motion of the motor 31, thereby driving the impurities to fall off the surface of the filter screen 33. At the same time, the telescopic column 41 automatically adjusts the position of the cleaning brush 36 according to the unevenness of the surface of the filter screen 33. The pressure spring 42 provides continuous pressure to keep the cleaning brush 36 pressed against the filter screen 33 at all times, ensuring good contact between the cleaning brush 36 and the filter screen 33, thereby driving the impurities on the filter screen 33 to further flow out of the filter tube 21 through the suction pipe 35 under the suction force of the suction device 34.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
