Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of open-loop condenser technology, specifically relating to an open-loop cooling water filtration device for condensers. Background Technology
[0002] In many industrial sectors such as power and chemical engineering, the condenser is a crucial piece of equipment. Its main function is to condense the exhaust steam from the turbine into water to maintain the turbine's vacuum and improve energy efficiency. The open-loop cooling water system, as a key component of the condenser, provides a continuous supply of cooling water to remove the heat released by the exhaust steam.
[0003] However, circulating cooling water often contains a large amount of impurities, such as silt and suspended solids. If these impurities are not effectively filtered and directly enter the condenser, they can cause blockages in the internal pipes of the condenser, reduce heat transfer efficiency, and thus affect the normal operation of the condenser, reduce the efficiency of the entire power generation or production system, and may even cause equipment failure, increasing maintenance costs and downtime. Therefore, efficient filtration of open-loop cooling water in condensers is of significant practical importance.
[0004] Some existing filtration devices use simple filter screens. These screens typically have a simple structure, usually consisting of one or more fixed-pore size screens installed in the pipe, relying on the physical interception effect of the screens to filter impurities. Other filtration devices use single-stage media filtration, such as using only a sand layer. Simple screen filtration devices usually lack a dedicated water distribution mechanism, resulting in uneven water flow through the screen. This leads to localized overburdening of the screen, further exacerbating clogging and reducing overall filtration efficiency. Another method involves directly introducing water into the sand layer, where impurities are intercepted through the pores. Some filtration devices have backwashing capabilities, but the backwashing methods are relatively traditional. They generally rely solely on reverse water flow to flush the filter media and remove accumulated impurities.
[0005] In view of this, we propose an open-loop circulating cooling water filtration device for condensers. Through multi-stage filtration, uniform water distribution, stable structural design and efficient cleaning method, it effectively overcomes many defects of the existing technology, and can provide higher quality circulating cooling water for condensers, ensuring the stable operation of condensers. Utility Model Content
[0006] The present invention aims to solve the technical problem in the prior art that the use of simple filter screens for filtration is inconvenient for water distribution and has poor filtration effect.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A condenser open-loop cooling water filtration device includes a filter tank, a water distributor, a media filter layer, a media fixing net, and a collection hopper.
[0009] The filter tank is formed by connecting an upper shell and a lower shell with flanges. The bottom of the lower shell is equipped with an inlet pipe, and the upper shell is equipped with an outlet pipe on one side of the upper end.
[0010] A water distributor is used to evenly distribute the flow rate. The water distributor includes a water distribution plate, several nozzles evenly distributed on the water distribution plate, and several annular rings fixed on the water distribution plate and arranged from the inside to the outside.
[0011] The media filter layer is located above the water distributor and is used for filtering impurities in the circulating cooling water. The media filter layer includes a fine sand layer, a coarse sand layer, and a gravel layer arranged sequentially from top to bottom. The media fixing net is used to separate the fine sand layer, the coarse sand layer, and the gravel layer to prevent them from mixing.
[0012] The collection hopper is located above the media fixing net and is connected to the outlet pipe, and is used to guide the filtered water to the outlet pipe.
[0013] Preferably, a lower flange ring is provided on the inner side of the bottom of the lower housing, and the water distributor is installed on the lower flange ring by flange bolts. A water inlet chamber for water intake is formed between the water distributor and the inner bottom wall of the lower housing.
[0014] Preferably, a sealing ring is provided between the lower flange ring and the water distribution pan, and a sealing block is provided on the sealing ring to be inserted into the through hole on the water distribution pan.
[0015] Preferably, the media fixing net includes a lower net placed on top of the annular ring, a partition net A above the gravel layer, a partition net B above the coarse sand layer, and an upper net above the fine sand layer.
[0016] Preferably, the annular ring is provided with a number of internally threaded cylinders. The lower mesh, partition A, partition B and the upper mesh are each provided with mounting holes that are vertically corresponding to the internally threaded cylinders. The media filter layer, the media fixing mesh and the water distributor are integrated and installed in the lower housing by a long screw that passes through the mounting holes of the lower mesh, partition A, partition B and the upper mesh and is threadedly connected to the internally threaded cylinders.
[0017] Preferably, the inner side of the upper shell is provided with an upper flange ring, and the connecting frames evenly distributed at the top of the collecting hopper are fixed to the upper flange ring by flange bolts.
[0018] Preferably, the water inlet pipe is connected to a sewage pipe, an air inlet pipe, and a flushing pipe, and each of the water inlet pipe, sewage pipe, air inlet pipe, and flushing pipe is equipped with a valve A.
[0019] Preferably, a backwash pipe is connected to the outlet pipe, and valves B are installed on both the outlet pipe and the backwash pipe.
[0020] Compared with the prior art, the technical effects and advantages of this utility model are:
[0021] The operation of this open-loop circulating cooling water filtration device for the condenser consists of two main stages: filtration and cleaning. In the filtration stage, circulating cooling water enters the inlet chamber formed by the water distributor and the inner wall of the lower shell through the inlet pipe at the bottom of the lower shell. The water is then evenly sprayed upwards through nozzles on the water distributor, distributing the water flow evenly to the upper media filter layer. The media filter layer comprises a fine sand layer, a coarse sand layer, and a gravel layer, which sequentially intercept impurities of different sizes, achieving multi-stage filtration. The filtered water is collected in a collection hopper and discharged through the outlet pipe. In the cleaning stage, backwashing is performed first. The inlet and outlet pipe valves are closed, and the backwash pipe valve is opened, allowing the reverse water flow to flush away impurities and discharge them through the drain pipe. Next, water-air cleaning is performed. The backwash pipe and outlet pipe valves are closed, and the flushing pipe and air inlet pipe valves are opened, creating a water-air mixed flow to further clean the media layer. Finally, the wastewater is discharged through the drain pipe.
[0022] The multi-stage filtration structure of this open-loop circulating cooling water filtration device for the condenser significantly improves filtration accuracy and efficiency. The combination of fine sand, coarse sand, and gravel layers effectively removes impurities of different sizes from the circulating cooling water, ensuring that the effluent water quality meets requirements. The water distributor design ensures that the water flow is evenly distributed across the media filter layer, avoiding excessively large or small local water flows, allowing the entire media filter layer to function fully, improving the stability of the filtration effect, and providing reliable water quality assurance for the normal operation of the condenser.
[0023] This open-loop cooling water filtration system for condensers boasts numerous structural advantages, facilitating maintenance and long-term stable operation. The filter tank utilizes upper and lower shell flange connections, simplifying installation and maintenance of internal components. The water distributor, media fixing mesh, and collection hopper are bolted together, ensuring fixed positions and easy disassembly and replacement. Sealing rings and blocks guarantee the system's airtightness, reducing the risk of water leakage. Furthermore, the combined backwashing and water-air cleaning method thoroughly removes impurities from the media layer, extending the filter media's lifespan and reducing operating costs.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0040] The following combination Figures 1 to 9 This application will be described in further detail.
[0041] This application discloses an open-loop cooling water filtration device for a condenser, comprising a filter tank 1, a water distributor 2, a media filter layer 3, a media fixing net 4, and a collection hopper 5.
[0042] The filter tank 1 is formed by flange connection of the upper shell 101 and the lower shell 102. The lower shell 102 is provided with a lower flange ring 105 on the inner side of the bottom, and the upper shell 101 is provided with an upper flange ring 107 on the inner side. The water distributor 2 is installed on the lower flange ring 105 by flange bolts. The water distributor 2 and the inner bottom wall of the lower shell 102 form a water inlet chamber 106 for water inlet.
[0043] The filter tank 1 is formed by flanged connection between the upper shell 101 and the lower shell 102. This flanged connection ensures a tight and reliable connection between the upper and lower shells 101 and 102. During installation, components can be easily placed into the lower shell 102 sequentially before being connected to the upper shell 101. When it is necessary to inspect, replace, or clean components such as the water distributor 2 and the media filter layer 3 inside the filter tank 1, simply removing the flange bolts easily separates the upper shell 101 and the lower shell 102, greatly improving maintenance convenience. Sealing gaskets can be installed on the flange connection to effectively prevent water leakage inside the filter tank 1, ensuring the normal operation of the filtration device and avoiding water waste and environmental impact.
[0044] Using flange bolts to install the water distributor 2 on the lower flange ring 105 ensures that the water distributor 2 is fixed in position within the filter tank 1, preventing displacement or shaking under water flow impact and ensuring the normal operation of the water distributor 2. The design of the inlet chamber 106 provides a buffer and diffusion space for the incoming water flow, which is conducive to the water flow entering the water distributor 2 more evenly, providing a foundation for subsequent uniform water distribution.
[0045] The water distributor 2 is used to evenly distribute the flow rate. The water distributor 2 includes a water distribution plate 202, a number of nozzles 203 evenly distributed on the water distribution plate 202, and a number of annular rings 204 fixed on the water distribution plate 202 and arranged from the inside to the outside.
[0046] Several evenly distributed nozzles 203 can spray water from the inlet chamber 106 upwards in a relatively uniform manner, so that the water flow is evenly distributed to the upper media filter layer 3, avoiding situations where the water flow is too large or too small in some areas, ensuring that the entire media filter layer 3 can fully perform its filtration function, and improving filtration efficiency and effect. The setting of the annular ring 204 enhances the structural strength of the water distribution plate 202, making it able to withstand the impact of water flow without being easily deformed, ensuring the long-term stable operation of the water distributor 2.
[0047] A sealing ring 6 is provided between the lower flange ring 105 and the water distribution tray 202. The sealing ring 6 has a sealing block 601 that inserts into the through hole 201 on the water distribution tray 202. The sealing ring 6 effectively fills the gap between the lower flange ring 105 and the water distribution tray 202, preventing water leakage from the connection point, ensuring the sealing of the water inlet chamber 106, and improving the working efficiency of the filtration device. The sealing block 601, inserted into the through hole 201 on the water distribution tray 202, serves a positioning function, ensuring the accurate installation position of the water distributor 2, and further enhancing the sealing effect.
[0048] The media filter layer 3 is located above the water distributor 2 and is used for filtering impurities from the circulating cooling water. The media filter layer 3 includes a fine sand layer 301, a coarse sand layer 302, and a gravel layer 303 arranged sequentially from top to bottom. The media fixing net 4 separates the fine sand layer 301, coarse sand layer 302, and gravel layer 303 to prevent them from mixing. The combination of the fine sand layer 301, coarse sand layer 302, and gravel layer 303 forms a multi-stage filtration structure. The fine sand layer 301 intercepts smaller impurities, the coarse sand layer 302 intercepts slightly larger impurities, and the gravel layer 303 intercepts even larger particles. This graded filtration can more effectively remove impurities of different sizes from the circulating cooling water, improving filtration accuracy. The media fixing net 4 separates the different media layers, preventing them from mixing under the impact of water flow, ensuring the independence and stability of each filtration layer, and thus maintaining consistent filtration performance.
[0049] The media fixing net 4 includes a lower net 401 placed on top of the annular ring 204, a partition net A402 located above the gravel layer 303, a partition net B403 located above the coarse sand layer 302, and an upper net 404 located above the fine sand layer 301. The nets at different positions fix each media layer, ensuring the stability of each layer and further preventing mixing between media layers. Simultaneously, these nets also provide some support to the media layers, ensuring uniform stress and preventing localized collapse or deformation. Each net layer is relatively independent, allowing for convenient operation during installation and replacement of media layers, thus improving maintenance efficiency.
[0050] The annular ring 204 has several internally threaded cylindrical columns 205 evenly distributed on it. The lower mesh 401, partition mesh A402, partition mesh B403, and upper mesh 404 are all provided with mounting holes 405 vertically corresponding to the internally threaded cylindrical columns 205. A long screw 7, passing through the mounting holes 405 in the lower mesh 401, partition mesh A402, partition mesh B403, and upper mesh 404 and threadedly connected to the internally threaded cylindrical columns 205, integrates the media filter layer 3, media fixing mesh 4, and water distributor 2 into the lower housing 102. This installation method connects the media filter layer 3, media fixing mesh 4, and water distributor 2 into a single unit, forming a stable structure within the filter tank 1. This not only facilitates overall installation and disassembly but also allows for better collaborative operation during operation, improving the overall performance of the filtration device. The threaded connection between the long screw 7 and the internally threaded cylinder 205 provides strong connection force, which can resist the impact and vibration of water flow, ensure the relative position of each component is fixed, and extend the service life of the filter device.
[0051] The collecting hopper 5 is located above the media fixing net 4 and is connected to the outlet pipe 104, serving to guide the filtered water to the outlet pipe 104. The shape and position design of the collecting hopper 5 effectively collects the water filtered through the media filter layer 3, converging the dispersed water flow for easy discharge through the outlet pipe 104. The well-designed collecting hopper 5 allows for smoother water flow into the outlet pipe 104, reducing flow resistance and improving drainage efficiency.
[0052] The connecting brackets 501, evenly distributed at the top of the collection hopper 5, are fixed to the upper flange ring 107 using flange bolts. Fixing the connecting brackets 501 of the collection hopper 5 to the upper flange ring 107 with flange bolts ensures the stability of the collection hopper 5 within the filter tank 1, preventing shaking or displacement under water flow impact and guaranteeing its normal collection and drainage functions. This connection method allows for easy and quick operation; simply remove the flange bolts when cleaning or replacing the collection hopper 5.
[0053] The lower housing 102 has a water inlet pipe 103 at its bottom, and the upper housing 101 has a water outlet pipe 104 on one side of its upper end. The water inlet pipe 103 is connected to a drain pipe 108, an air inlet pipe 109, and a flushing pipe 110, and valves A111 are respectively installed on the water inlet pipe 103, the drain pipe 108, the air inlet pipe 109, and the flushing pipe. The water outlet pipe 104 is connected to a backwash pipe 112, and valves B113 are respectively installed on the water outlet pipe 104 and the backwash pipe 112.
[0054] The inlet pipe 103 is used to introduce the circulating cooling water to be filtered, and the outlet pipe 104 is used to discharge the filtered water. The drain pipe 108 can discharge impurities and sewage during the cleaning process; the air inlet pipe 109 and the flushing pipe 110 can introduce gas and flushing water when needed to achieve water-air cleaning function; the backwash pipe 112 can perform reverse flushing to remove impurities from the media filter layer 3. The valves on each pipe can be controlled independently, and the on / off state and flow rate of water and air can be flexibly adjusted according to different working requirements and operating conditions, improving the operational flexibility and adaptability of the filtration device.
[0055] After water enters through inlet pipe 103, it is distributed sequentially by water distributor 2, filtered through fine sand layer 301, coarse sand layer 302, and gravel layer 303, and then collected by collection hopper 5 before being discharged through outlet pipe 104. This design forms a continuous and orderly filtration process. From water inlet to water distribution, multi-stage filtration, and water outlet, each link works closely together to efficiently remove impurities from the circulating cooling water, ensuring that the outlet water quality meets requirements. Through multi-stage filtration and uniform water distribution, the filtration effect is more stable, and the fluctuation of the outlet water quality is smaller, providing a reliable water quality guarantee for the normal operation of the condenser.
[0056] When the entire filter needs to be cleaned, backwashing can be performed through backwash pipe 112, and impurities can be discharged through drain pipe 108. In addition, after backwashing, water and air are introduced into the filter tank 1 through a combination of flushing pipe and air inlet pipe 109 for water and air cleaning. After water and air cleaning, the impurities are discharged through drain pipe 108.
[0057] This condenser open-loop circulating cooling water filtration device utilizes different media (fine sand layer 301, coarse sand layer 302, and gravel layer 303) in the media filter layer 3 to physically intercept and filter impurities in the circulating cooling water. Media of different particle sizes can sequentially intercept impurities of different sizes. The fine sand layer 301 intercepts smaller impurities, the coarse sand layer 302 intercepts slightly larger impurities, and the gravel layer 303 intercepts even larger particles, thus achieving multi-stage filtration of the circulating cooling water and purifying the water quality.
[0058] Circulating cooling water enters from the water inlet pipe 103 at the bottom of the lower housing 102. A valve A111 is provided on the water inlet pipe 103 to control the water flow rate. At this time, the valve A111 is opened, and water flows into the water inlet chamber 106 at the bottom of the lower housing 102. The water inlet chamber 106 is formed by the water distributor 2 and the inner bottom wall of the lower housing 102.
[0059] Water entering the inlet chamber 106 is evenly distributed through the water distributor 2. The water distributor 2 includes a water distribution plate 202, a plurality of nozzles 203 evenly distributed on the water distribution plate 202, and a plurality of annular rings 204 fixed on the water distribution plate 202 and arranged from the inside to the outside. Water is evenly sprayed upward through the nozzles 203, so that the water flow can enter the upper media filter layer 3 relatively evenly.
[0060] The water sprayed upwards passes sequentially through the gravel layer 303, coarse sand layer 302, and fine sand layer 301 of the media filter layer 3. The fine sand layer 301 first intercepts larger particles from the gravel layer 303, then the coarse sand layer 302 intercepts slightly larger impurities, and finally intercepts smaller impurities in the water. Through these three stages of filtration, impurities in the water are effectively removed.
[0061] After filtration and purification, the water continues to flow upwards and reaches the collection hopper 5 located above the media fixing net 4. The collection hopper 5 collects the filtered water and discharges it through the water outlet pipe 104 connected to the collection hopper 5. The water outlet pipe 104 is equipped with a valve B113 to control the water flow rate.
[0062] The cleaning principle and process are as follows:
[0063] The cleaning process mainly includes two stages: backwashing and water-air cleaning. Backwashing uses reverse water flow to flush out impurities intercepted in the media filter layer 3, allowing them to be discharged through the drain pipe 108 with the water flow. Water-air cleaning involves introducing water through the flushing pipe and air through the air inlet pipe 109, forming a water-air mixed flow to further clean the media filter layer 3. The agitation of the gas and the flushing action of the water flow more thoroughly remove impurities from the media layer. Finally, the cleaned wastewater is discharged through the drain pipe 108.
[0064] The backwashing process is as follows:
[0065] Close valve A111 on inlet pipe 103 and valve B113 on outlet pipe 104 to stop water intake.
[0066] Open valve B113 on backwash pipe 112 to allow water to enter filter tank 1 from backwash pipe 112. The water flows in reverse, down from collection hopper 5 through media filter layer 3, flushing up the impurities intercepted in media filter layer 3. Open valve A111 on drain pipe 108, and the flushed impurities are discharged from filter tank 1 with the water flow through drain pipe 108, completing the backwashing process.
[0067] Water and air cleaning stage
[0068] After backwashing is complete, close valve B113 on backwash pipe 112 and valve B113 on outlet pipe 104. Open valve A111 on flushing pipe and air inlet pipe 109 to simultaneously introduce water and air into filter tank 1. Water and air form a water-air mixture in filter tank 1. The agitation of the air makes it easier to loosen impurities in the filter media layer 3, while the water flow washes away the loosened impurities. Open valve A111 on drain pipe 108 to discharge the cleaned wastewater from filter tank 1 through drain pipe 108, completing the water-air cleaning process.
[0069] In summary, this filtration device, through its reasonable structural design and workflow, achieves effective filtration of circulating cooling water and its own cleaning and maintenance.
