Description

Technical Field

[0001] The present disclosure relates to the technical field of steam turbine accessories, and in particular to a condensate filter. Background Art

[0002] The condensate of the power plant is composed of the condensate of the steam turbine condenser and the heater drain in the auxiliary thermal system of the steam turbine. The condensate is condensed from steam and the water quality should be extremely pure. However, in reality, these condensates often have a certain degree of pollution, containing suspended and colloidal metal corrosion products and trace organic matter. In the application process, the condensate is combined with the feed water to become the boiler feed water. Therefore, ensuring the water quality of the condensate and the feed water is the premise of making the feed water quality good. When the condensate is recycled, it needs to be filtered. During the initial filtration, it is often used. The filter screen filters out suspended and colloidal metal corrosion products, but after long-term use, some impurities will adhere to the filter screen, causing the filter screen to be blocked. The efficiency of condensate water passing through is greatly reduced and needs to be cleaned in time. The current cleaning method often involves taking out the filter screen and flushing it, which is cumbersome and affects the efficiency of filtering condensate water and is inconvenient to use. There are also some cleaning methods that clean the impurities attached to the filter screen, but after cleaning, the impurities will be re-attached to the filter screen in a short time because they are not discharged in time.

[0026] The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and understanding the present disclosure, and are not used to limit the present disclosure.

[0027] In the present disclosure, unless otherwise stated, the orientation terms such as "inside, outside" refer to the inside and outside relative to the contour of the component or structure itself. In addition, it should be noted that the terms such as "first, second" are used to distinguish one element from another, and do not have sequence and importance. In addition, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0028] The present disclosure provides a condensate filter screen, including: a frame body 1; a filter screen 3 fixedly installed in the frame body 1; and a cleaning component 2 movably arranged on the frame body 1 along the surface of the filter screen 3 in a reciprocating manner, and a sewage extraction port 202 is provided on one side of the cleaning component 2 in contact with the filter screen 3 to extract the attachments on the filter screen 3.

[0029] Through the above technical solution, the filter screen 3 is fixedly installed in the frame body 1 for filtering condensate. The cleaning component 2 is arranged on the frame body 1 and can move reciprocally along the surface of the filter screen 3 to clean the filter screen 3 comprehensively. A sewage extraction port 202 is provided on one side of the cleaning component 2 in contact with the filter screen 3 to extract the attachments on the filter screen 3, so as to discharge the attachments in time and separate them from the filter screen 3, and prevent the attachments from reattaching to the filter screen 3 and causing unclean cleaning.

[0030] As an alternative embodiment, as Figures 1-5As shown, the cleaning assembly 2 includes a cleaning plate 201, a first accommodating chamber 207 is provided inside the cleaning plate 201, a plurality of sewage suction ports 202 are provided, and the plurality of sewage suction ports 202 are arranged at intervals along the extension direction of the cleaning plate 201, the sewage suction ports 202 are communicated with the first accommodating chamber 207, the first accommodating chamber 207 is used to be connected to the sewage discharge device, and the plurality of sewage suction ports 202 are arranged along the extension direction of the cleaning plate 201 to expand the cleaning area, and the sewage suction ports 202 adsorb the attached matter on the filter screen 3 to the first accommodating chamber 207. The sewage in a accommodating chamber 207 is then sucked out through a sewage discharge device. The sewage discharge device is a power device with a suction function, such as a water pump. The water pump causes the sewage outlet 202 to generate suction to remove the attachments on the filter 3. Since multiple sewage outlets 202 are provided, a first accommodating chamber 207 is provided in the cleaning plate 201 to connect the multiple sewage outlets 202 so that each sewage outlet 202 has suction, and the attachments removed by the sewage outlet 202 are gathered in the first accommodating chamber 207 and sucked away uniformly.

[0031] Alternatively, if Figures 1-2 As shown, the cleaning assembly 2 is provided with at least one group, and the cleaning assembly 2 also includes a telescopic hose 204. The frame 1 is provided with a second accommodating chamber 102, and the first accommodating chamber 207 is communicated with the second accommodating chamber 102 through the telescopic hose 204. Because the cleaning plate 201 needs to reciprocate during cleaning, a telescopic hose 204 is provided to connect the first accommodating chamber 207 with the second accommodating chamber 102. The telescopic hose 204 can be deformed and retracted according to the movement of the cleaning plate 201, and does not affect the movement of the cleaning plate 201. The frame 1 is provided with a quick connector 103 for connecting with a sewage discharge device, and the quick connector 103 is communicated with the second accommodating chamber 102, that is, the sewage discharge device is connected to the frame 1. On the one hand, the frame 1 is fixedly arranged, which is convenient for connecting the sewage discharge device. On the other hand, impurities in multiple cleaning assemblies 2 can be uniformly summarized in the frame 1 and drawn away through the sewage discharge device, and each cleaning assembly 2 does not need to be provided with a sewage discharge device, so that the device is simpler and the cost is lower. Of course, in other embodiments, the sewage discharge device can also be directly connected to the cleaning plate 201 through the telescopic hose 204.

[0032] As an optional implementation, Figures 1-4 As shown, the first end of the cleaning plate 201 is rotatably connected to the frame 1, and the second end opposite to the first end extends into the range of the frame 1 and swings along the first end. The cleaning plate 201 is in a swinging state, and reciprocates along the first end to clean the filter 3. In other embodiments, the cleaning plate 201 can also be slidably connected to the frame 1, and its two ends are slidably connected to the two sides of the frame 1 to move along the frame 1.

[0033] In addition, if Figures 2-4As shown, the cleaning component 2 also includes a driving device 206 and a connecting shaft 205. The frame 1 is provided with an axial hole 101 for the connecting shaft 205 to pass through. One end of the connecting shaft 205 is fixedly connected to the first end, and the other end passes through the axial hole 101 and is connected to the driving device 206 to drive the cleaning plate 201 to swing. The driving device 206 is fixedly connected to the frame 1. For example, the driving device 206 is a miniature waterproof servo motor, which drives the cleaning plate 201 to swing back and forth through the reciprocating forward and reverse rotation of the servo motor.

[0034] Among them, Figures 1-2 As shown, the frame 1 is constructed as a rectangular frame, and two cleaning components 2 are provided. The first ends of the two cleaning plates 201 are respectively connected to the two opposite corners of the rectangular frame. The swing angle of the cleaning plate 201 is 90°. The cleaning plates 201 are installed on the two diagonal corners of the rectangular frame and the swing angle is 90°. While minimizing the overlapping area of ​​the two cleaning plates 201, the swing range of the two cleaning plates 201 can fully cover the filter 3, and being arranged at the corner can make the length of the cleaning plate 201 as long as possible to increase the cleaning area.

[0035] Alternatively, if Figure 1 As shown, the two cleaning plates 201 are arranged on the same side of the filter 3 and the side is the side of the filter 3 facing the object to be filtered. Most of the impurities are attached to the side of the filter 3 facing the object to be filtered, so it is sufficient to focus on cleaning this side. The sewage extraction port 202 will also extract a small amount of attachments on the back when extracting. Of course, the two cleaning plates 201 can also be respectively arranged on both sides of the filter 3, or two more cleaning plates 201 can be added and arranged on the other side of the filter 3 and on the other two corners.

[0036] Alternatively, if Figure 1 As shown, the length of the cleaning plate 201 is L1, the side length of the rectangular frame is L2, and 1 / 2L2<L1<L2, 1 / 2L2<L1 can ensure that the swing range of the two cleaning plates 201 can fully cover the filter 3. In order to increase the cleaning area of ​​the two cleaning plates 201, the length of the cleaning plate 201 should be extended as much as possible, L1<L2 to avoid the cleaning plate 201 extending out of the frame 1, and the two cleaning plates 201 swing intermittently and are in a swinging state at different times to avoid collision between the two cleaning plates 201.

[0037] As an optional implementation, Figures 3-5As shown, the cleaning component 2 also includes a cleaning brush 203, which is arranged on the side of the cleaning component 2 that contacts the filter 3. The condensate filter is used to filter the condensate generated by the steam turbine. The condensate generated by the steam turbine contains suspended and colloidal metal corrosion products and trace organic matter, and the attached matter after filtration has a certain viscosity and will adhere to the filter 3. The cleaning brush 203 cleans the surface of the filter 3 to remove impurities attached to the surface of the condensate. After cleaning, the condensate containing a large amount of impurities is extracted through the sewage extraction port 202 to avoid the impurities cleaned from re-attaching to the filter 3 during subsequent use, thereby improving the cleaning effect and stability during filtration.

[0038] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0039] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0040] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
