Description

Technical Field

[0001] The present invention relates to the technical field of image processing, and in particular to an image processing system, method and device for froth flotation identification. Background Art

[0002] In an industrial production environment, froth flotation is a separation method that utilizes the difference in natural surface activity of the substances to be separated. During the flotation process, the camera is used to monitor and identify the flotation image in real time. Therefore, as a key imaging device in the froth flotation identification process, the installation and use environment of the camera lens is relatively complex and needs to adapt to different environments, so the camera function requirements are relatively high.

[0003] In the relevant prior art, factories deal with lens contamination by regularly cleaning camera lenses manually or automatically; although some industrial cameras are equipped with automatic cleaning mechanisms, such as fans or brushes, inappropriate cleaning frequency may result in waste of resources and deterioration of image quality.

[0004] Some factories use the powerful computing power of cloud computing to perform image restoration. However, cloud processing requires time to upload data to the cloud server, and then wait for the cloud server to complete processing and download the results. This round-trip process introduces delays, which may not be suitable for industrial production that requires a quick response. In addition, cloud computing services are usually charged based on usage, and processing a large number of images may incur high costs, especially for services that need to run for a long time. This results in low image processing efficiency in the image processing system and high long-term usage costs.

[0060] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0061] The invention provides a picture processing system.

[0062] Please refer to Figures 1 to 3 , the image processing system comprises:

[0063] An image acquisition module, an image analysis module, a picture defogging module and a physical defogging module; the image acquisition module acquires the picture image identified by foam flotation through a high-definition camera; the image analysis module and the picture defogging module are integrated and installed in an edge server, and the image analysis module is used to analyze the pollution degree of the picture image;

[0064] The image defogging module is used to remove water mist from the image through the system defogging function;

[0065] The physical defog module is used to physically defog the lens end of the high-definition camera.

[0066] The image analysis module is used to analyze and judge the degree of image pollution in the picture to determine whether there is fog in the picture taken by the camera, and to select automatic defogger or physical defogger according to the result of the judgment.

[0067] The image defogging module is used for automatic defogging, and uses an image defogging algorithm to achieve defogging of images with a low degree of pollution, thereby enhancing the clarity of the image and achieving an automatic defogging effect.

[0068] Automatically determine whether there is fog on the camera through the image captured by the camera.

[0069] If it is determined that fog exists, the density level of the fog is determined.

[0070] The density levels are divided into three categories: low, medium, and high. If the density level is medium or high, the camera will be wiped automatically.

[0071] If the density level is low, the image defogging algorithm is used to remove the water mist, and there is no need to wipe it, which reduces unnecessary operations and extends the service life of the equipment.

[0072] By processing data offline, complex data uploading steps are avoided, making the entire process more efficient and easier to manage; reducing dependence on high network bandwidth, and no longer needing to frequently upload large amounts of data to the cloud, saving network resources and significantly reducing data transmission costs; processing data instantly at the data source, with a faster response speed; edge computing solutions significantly reduce dependence on centralized cloud computing resources by deploying lightweight models near the data source, which not only reduces costs but also enhances system reliability and availability. Local data processing means less data transmission, which reduces the risk of privacy leaks.

[0073] In this embodiment, the system uses Resnet-18 to determine whether the imaging device is contaminated. If so, the device needs to be automatically wiped, otherwise it enters the image defogging part;

[0074] First, a batch of imaging data needs to be collected and marked by professionals to see whether it can be identified by naked eyes. If it can be identified, it will be marked as a classification category, otherwise it will be marked as a polluted image. The system uses resnet-18 to classify whether it is a polluted image.

[0075] For recognizable images, the image dehazing and restoration stage is entered. The system adopts the Transformer codec method of the U-Net architecture. This method can not only capture long-distance dependencies, but also reduce computational complexity. The overall framework diagram is as follows: Figure 2 shown.

[0076] Specifically, the components of the system are as follows:

[0077] Multi-head transposition attention module TC-Attention;

[0078] Linear complexity: In traditional self-attention mechanisms, since each pixel interacts with all other pixels, the computational complexity is often quadratic, which can lead to a huge computational burden when processing high-resolution images. The system's multi-head attention module significantly reduces computational complexity by applying self-attention on the feature dimension rather than on the spatial dimension; this design enables the model to more efficiently capture long-range pixel interactions in images; in addition, MDTA also uses TOP-K technology to achieve sparse attention, which not only further reduces the amount of computation, but also effectively alleviates the overfitting problem; for details, please refer to Figure 3; This linear complexity design enables TCformer to process larger and more complex image data while maintaining high performance; at the same time, through sparse attention, the model can focus more on the most important parts of the image, thereby improving the generalization ability of the model.

[0079] Attention in the feature dimension: Different from traditional multi-head self-attention, MDTA applies self-attention in the feature dimension; this enables TCtormer to process high-resolution images more effectively.

[0080] The specific formula of the multi-head transposed attention module is as follows:

[0081] ;

[0082] ;

[0083] Where Q, K, and V represent query, key, and value respectively.

[0084] In order to represent the features after the TC-Attention module, we use a feedforward neural network. A feedforward neural network (FFN) is a basic artificial neural network structure, mainly composed of an input layer, a hidden layer, and an output layer. In this network, information flows in only one direction, from the input layer through the hidden layer to the output layer, without reverse information flow or loops (unlike recursive neural networks and recurrent neural networks). Its mathematical description is as follows:

[0085] ;

[0086] The system generally adopts the U-Net architecture to realize feature extraction and enhance gradient flow. The specific advantages are as follows:

[0087] Symmetric encoder-decoder architecture: Tcformer uses a 4-level symmetric encoder-decoder architecture, which enables the model to capture image features at different scales;

[0088] Local-global balance: Thanks to the hierarchical multi-scale representation, Tcformer is able to consider both the local and global characteristics of the image, thus achieving better performance on image restoration tasks.

[0089] Model efficiency calculation table:

[0090] It can be seen that in actual applications, the processing speed of this patent solution reaches 35 frames per second (fps), which is significantly higher than the 22 frames per second of the FFANET solution. The image processing model parameters proposed in this patent are only 1.3M, which is significantly reduced compared to the 4.45M parameters of the traditional solution FFANET.

[0091] Edge computing is a distributed computing framework that moves data processing and storage from centralized data centers to near the data source by using fewer and more economical edge devices on the production line to process data instead of relying on expensive central servers as traditional solutions do.

[0092] The present invention also provides a picture processing method, which uses the picture processing system to process the pictures in the foam flotation identification process.

[0093] In this embodiment, the image processing method significantly reduces the data transmission time by processing the data instantly at the location where the data is generated, thereby improving the response speed, and the fps is 35;

[0094] Edge computing deploys lightweight models near data sources. Since data is processed locally, only necessary data is sent to central servers or cloud servers. This reduces the use of network bandwidth, especially in industrial applications with large amounts of data, which can significantly reduce network burden and data transmission costs.

[0095] By processing data locally, data transmission over the Internet is reduced, thereby reducing the risk of data leakage or interception.

[0096] The invention provides a froth flotation identification device for collecting screen images of froth flotation identification.

[0097] First embodiment:

[0098] Please refer to Figures 4 to 7 In a first embodiment of the present invention, a froth flotation identification device comprises:

[0099] The mounting mechanism 1 comprises a mounting frame 11, a first connection cover 12, a second connection cover 13, an isolation cover 14, a sealing ring 15 and a sealing cover plate 16. The two sides of the mounting frame 11 are respectively fixedly connected to the first connection cover 12 and the second connection cover 13. The isolation cover 14 is fixedly mounted on the first connection cover 12. The sealing ring 15 is fixedly mounted on the mounting frame 11. The sealing cover plate 16 is fixedly mounted on the sealing ring 15. The sealing cover plate 16 is a heat-conducting plate. The mounting frame 11 is provided with a mounting groove 111. The second connection cover 13 is provided with an air inlet 131, a drainage cavity 132 and an air outlet 133.

[0100] A control main board 2, wherein the control main board 2 is mounted on the mounting frame 11, and the control main board 2 is assembled within the range of the mounting slot 111;

[0101] A lens module 3, wherein the lens module 3 is assembled on the first connection cover 12, and the lens module 3 is plugged into the control main board 2;

[0102] A blowing device 4, the blowing device 4 is installed on the second connecting cover 13, the blowing device 4 is installed within the range of the air inlet 131, the air inlet 131 is aligned with the surface of the sealing cover plate 16, and the drainage cavity 132 is connected with the air inlet 131 and the air outlet 133;

[0103] Among them, when the lens module 3 is in a normal working state, the mounting frame 11, the first connecting cover 12, the lens module 3, the sealing ring 15 and the sealing cover plate 16 form a sealed space, which provides a sealed use environment for the connection part between the control main board 2 and the lens module 3; the blowing device 4 can blow air to cool the sealing cover plate 16 from the outside of the sealed space.

[0104] In this embodiment, the isolation cover 14 is a transparent explosion-proof glass, which provides support for normal image acquisition of the lens module 3.

[0105] In this embodiment, the connection between the lens module 3 and the first connection cover 12 is sealed; the sealing cover plate 16 is made of heat-conducting material, which can achieve heat conduction between the control mainboard 2 and the lens module 3.

[0106] When the lens module 3 is in normal use, the mounting frame 11, the first connection cover 12, the isolation cover 14, the sealing ring 15 and the sealing cover plate 16 form a sealed space, so that the lens module 3 and the control main board 2 are isolated from the external environment, reducing the range of water vapor in the air flowing into the sealed space, keeping the lens end of the lens module 3 dry, and extending the adaptability and stability of the lens module 3 and the control main board 2 to the use environment;

[0107] When the sealed space needs to be cooled, the blowing device 4 is started, and the blowing device 4 blows air toward the range of the drainage cavity 132 through the air inlet 131, so that the surface of the sealing cover plate 16 is affected by the blowing cooling to achieve the effect of cooling.

[0108] Ultimately, while ensuring that the blowing device 4 can normally blow air to cool the working environment of the control mainboard 2, the connection between the control mainboard 2 and the lens module 3 is maintained within a sealed space to prevent the external environment from interfering with the connection between the control mainboard 2 and the lens module 3.

[0109] In this embodiment, the mounting mechanism 1 further includes an elastic member 17, one end of which is fixedly connected to the sealing cover plate 16, and the other end of which is abutted between the mounting frame 11 and the control main board 2. The elastic member 17 is made of insulating material and is used to provide a limiting effect for the installation and locking of the control main board 2.

[0110] In an optional embodiment, the blowing device 4 may be an external blowing device, which is connected to the air inlet 131 via a connecting air duct, and the blowing device can transport a cooling air source into the air inlet 131 via the connecting air duct.

[0111] In another alternative embodiment, please refer again to Figure 7 The blowing device 4 includes a fixed shaft 41, a first motor 42 and a fan blade 43. The fixed shaft 41 is fixed on the second connection cover 13, the first motor 42 is fixed on the fixed shaft 41, and the fan blade 43 is fixed on the rotating shaft of the first motor 42. The fan blade 43 is driven to rotate by the first motor 42, so that when the fan blade 43 rotates, the cooling gas is drawn from the outside through the air inlet 131 and blown toward the sealing cover plate 16. After blowing, the cooling gas is transported toward the air outlet 133 through the drainage cavity 132, so that the heat exchanged gas is discharged from the air outlet 133.

[0112] In this embodiment, the first motor 42 provides a power source for the rotation adjustment of the fan blades 43 and provides a stable wind source for cooling the device.

[0113] Please refer again Figure 4 The froth flotation identification device further comprises a mounting cover 5, and the second connection cover 13 is movably mounted on the mounting cover 5; the movably connected means that when the second connection cover 13 is not subjected to external forces, the second connection cover 13 is stably mounted on the mounting cover 5; when the second connection cover 13 is manually twisted, the second connection cover 13 can be rotated and adjusted on the mounting cover 5. When the use angle of the lens module 3 needs to be adjusted, it is convenient to manually adjust the second connection cover 13 to rotate on the mounting cover 5.

[0114] In this embodiment, the outer surface of the second connecting cover 13 is rotatably mounted on the inner side of the mounting cover 5 via a rotating shaft; however, a rubber ring is sleeved on the connecting shaft, and the surface of the rubber ring abuts against the inner side of the mounting cover 5 to limit the position, so that the connection between the second connecting cover 13 and the mounting cover 5 is frictionally braked. Therefore, when the second connecting cover 13 is not manually twisted, the installation angle between the second connecting cover 13 and the mounting cover 5 is fixed and will not loosen.

[0115] Please refer again Figure 4The foam flotation identification device also includes a second motor 6, which is fixed on the mounting cover 5. The shaft end of the second motor 6 passes through the mounting cover 5 and is fixedly connected to the second connecting cover 13. The second motor 6 is used to drive the second connecting cover 13 to rotate and adjust relative to the mounting cover 5.

[0116] In the preferred embodiment of this invention, please refer to Figure 8 and Fig. 9 The froth flotation identification device further comprises a heat conducting device 7, one end of which is in contact with the control main board 2, and the other end of which passes through the mounting frame 11 and is inserted into the range of the drainage cavity 132. The heat conducting device 7 increases the range and efficiency of heat conduction cooling.

[0117] In an optional embodiment, the heat conducting device 7 may be an independent heat conducting rod, which directly passes through the mounting frame 11 and abuts against the control main board 2 , so that the heat source generated by the control main board 2 and the sealed environment can be exchanged and cooled through the heat conducting device 7 .

[0118] In another optional implementation, please refer to Figure 8 and Fig. 9 The heat-conducting device 7 includes a heat-conducting shaft 71, a heat-conducting ring 72 and a heat-conducting bar 73. The heat-conducting shaft 71 is in an L-shaped structure. One end of the heat-conducting shaft 71 passes through the mounting frame 11 and is inserted into the range of the drainage cavity 132. The other end of the heat-conducting shaft 71 is fixedly connected to the heat-conducting ring 72. The heat-conducting bar 73 is fixedly arranged on the heat-conducting ring 72, and the heat-conducting bar 73 abuts against the control main board 2.

[0119] In this embodiment, the heat-conducting shaft 71, the heat-conducting ring 72 and the heat-conducting strip 73 are all made of heat-conducting materials, such as copper, for conducting heat between the control main board 2 and the lens module 3, and then contacting with the cooling air source for heat exchange to improve the effect of air cooling.

[0120] By arranging the heat-conducting ring 72 between the control main board 2 and the lens module 3, and arranging it around the plug-in part, the normal plug-in and use of the lens module 3 are not affected; the heat generated by the control main board 2 and the lens module 3 is conveniently conducted to the drainage cavity 132 at the same time, and the heat is cooled by blowing through the blowing device 4, and the heat is quickly blown out from the air outlet 133, so as to facilitate the stable use of the lens module 3.

[0121] In this embodiment, the heat conducting strip 73 is separated from the electronic components on the control main board 2 and does not affect the normal installation and use of the control main board 2 .

[0122] Please refer again Fig. 9 At least nine groups of heat-conducting shafts 71 are provided, and the nine groups of heat-conducting shafts 71 are arranged around the heat-conducting ring 72. The heat exchange range inside the drainage cavity 132 is increased, and the heat exchange and cooling efficiency within the sealed space is improved.

[0123] The working principle of the froth flotation identification device provided in this embodiment is as follows:

[0124] A1 When the control mainboard 2 and the lens module 3 need to be ventilated and cooled, the first motor 42 is started, the first motor 42 drives the fan blades 43 to rotate, and the fan blades 43 transport cooling air from the air inlet 131 toward the range of the drainage cavity 132;

[0125] A2 When the cooling air source enters the drainage cavity 132, the cooling air source contacts the heat-conducting shaft 71 and exchanges heat, so that the cooling air source is converted into hot air.

[0126] A3 The hot air is quickly discharged through the air outlet 133, thereby discharging most of the heat generated by the control mainboard 2 and the lens module 3 during use, which helps to stabilize the operation and heat dissipation of the control mainboard 2 and the lens module 3.

[0127] Second embodiment:

[0128] In froth flotation processes, especially those involving high humidity, high temperature or liquid handling, cameras are often affected by water mist, which may come from a variety of sources such as steam, spray, condensation, etc. Water mist pollution may cause the camera image quality to drop by 30-50%, which is unacceptable for industrial applications that require high-precision image analysis and classification; therefore, the development of cameras with defogging capabilities has important application significance.

The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0132] The adjusting device 9 includes a third motor 91, a gear 92 and a toothed ring 93. The third motor 91 is fixed on the first connecting cover 12. The third motor 91 is installed inside the first connecting cover 12. The gear 92 is fixed on the rotating shaft of the third motor 91. The toothed ring 93 is fixed on the adjusting cover 8.

[0133] Among them, the toothless ring 93 is arranged within the range of the active cavity 121, the surface of the gear 92 passes through the connecting cavity 122 and penetrates into the range of the active cavity 121, and the gear 92 is meshed and connected with the toothless ring 93; when the gear 92 rotates, the toothless ring 93 drives the adjustment cover 8 to rotate and adjust around the first connecting cover 12, the mounting frame 11 and the second connecting cover 13 as a whole, so as to control the adaptive opening of the air inlet 802, which is used to guide the hot air from the air outlet 133 to the first air outlet 803 and the drainage port 123 for blowing, so as to realize the blowing, drying and cleaning of the inner side of the lens module 3 and the isolation cover 14.

[0134] In this embodiment, the two guide ports 123 are symmetrically arranged on the first connection cover 12 ; one guide port 123 is arranged corresponding to the first air outlet 803 ; the other guide port 123 is arranged corresponding to the exhaust port 804 .

[0135] In this embodiment, the rotating mouth 801 is not connected to the hollow structure of the adjusting cover 8. The rotating mouth 801 provides support for the stable rotation of the adjusting cover 8 relative to the first connecting cover 12, the mounting frame 11, and the second connecting cover 13, and will not conflict with the shaft end of the mounting cover 5 or the second motor 6, thereby ensuring the stable operation of the equipment.

[0136] In this embodiment, the movable cavity 121 provides a movable space for the rotation adjustment of the toothless ring 93 , and the toothless ring 93 will not contact or collide with the first connecting cover 12 when rotating.

[0137] In this embodiment, the adjustment cover 8 includes two usage modes:

[0138] Mode 1, closed mode, when the adjustment cover 8 is in closed mode, the air inlet 123 is closed, the camera end of the lens module 3 is sealed, the air outlet 133 is connected to the outside, and the air inlet 802, the first air outlet 803 and the exhaust port 804 are all closed, so as to facilitate the normal heat exchange and operation of the lens module 3 and the control main board 2:

[0139] Mode 2: Open mode. When the adjustment cover 8 is in the open mode, the drainage port 123 is opened, the camera end of the lens module 3 is opened for ventilation, the air outlet 133 is connected to the air inlet 802, and the air inlet 802, the first air outlet 803 and the exhaust port 804 are all opened, so that the hot air blown out from the air outlet 133 can be used to provide air blowing, demisting and cleaning for the isolation cover 14 and the lens module 3.

[0140] Please refer again Fig.15 In the present embodiment, one end of the adjusting cover 8 close to the second connecting cover 13 is a semicircular ring structure, and the cover is on the end of the second connecting cover 13 (the side facing the air outlet 133), and the air inlet 802 is arranged on the semicircular ring structure. When the adjusting cover 8 is in the closed mode, the semicircular ring structure and the air outlet 133 are staggered, and the air outlet 133 is connected with the outside; when the adjusting cover 8 is in the open mode, the semicircular ring structure completely blocks the air outlet 133, and the air inlet 802 is connected with the air outlet 133.

[0141] In this embodiment, the air inlet 802 is connected to the hollow structure of the adjusting cover 8; the first air outlet 803 is connected to the hollow structure of the adjusting cover 8, and the first air outlet 803 faces the inner side surface of the isolation cover 14 and the lens end of the lens module 3. When the first air outlet 803 blows air, the inner side surface of the isolation cover 14 and the lens end of the lens module 3 can be blown to defog and clean and maintain; the exhaust port 804 is connected to the hollow structure of the adjusting cover 8, and when the first air outlet 803 blows air, the exhaust port 804 can quickly discharge the blown-in gas.

[0142] In this embodiment, the connection between the lens module 3 and the first connection cover 12 is sealed, so that even if the drainage port 123 is opened, the control mainboard 2 is still within the range of the sealed space, thereby ensuring the sealing of the control mainboard 2.

[0143] When the lens module 3 is operating normally, the adjustment cover 8 is in the closed mode, the lens module 3 can be monitored and used normally, and the blowing device 4 can be used to blow air to cool the inside of the drainage cavity 132, and the heat-exchanged gas is blown out from the air outlet 133. During this period, the lens module 3 maintains a sealed use environment;

[0144] When the lens module 3 needs to be maintained by blowing, the third motor 91 is started, the third motor 91 drives the gear 92 to rotate, the gear 92 drives the toothed ring 93 to rotate, the toothed ring 93 drives the adjustment cover 8 to rotate and switch from the closed mode to the open mode, so that the air inlet 802 is connected to the air outlet 133, the first air outlet 803 is connected to one of the drainage ports 123, the exhaust port 804 is connected to another drainage port 123, and the heat exchange gas blown out of the air outlet 133 can be blown and dried through the hollow adjustment cover 8 to the inner side of the isolation cover 14 and the lens end of the lens module 3, so as to achieve the purpose of demisting and blowing cleaning;

[0145] Finally, the control mainboard 2 and the lens module 3 are cooled by air blowing, and the lens end of the lens module 3 and the inner side of the isolation cover 14 are demisted and cleaned by air blowing after heat exchange.

[0146] Please refer again Fig.14 The adjustment cover 8 is also provided with a second air outlet 805, which is aligned with the outer side of the isolation cover 14 and communicated with the hollow structure of the adjustment cover 8. When the adjustment cover 8 is in the open mode, the second air outlet 805 can blow air toward the outer side of the isolation cover 14 to perform demisting and dust removal, so that the equipment can perform synchronous cleaning and maintenance on both sides of the isolation cover 14.

[0147] In an optional implementation manner of the present application, a dust filter may be added to the input end of the air inlet 131 to reduce the entry of external dust and flying insects and extend the service life of the equipment.

[0148] The working principle of the froth flotation identification device provided in this embodiment is as follows:

[0149] like Fig.15 and Fig.18 As shown, when the adjustment cover 8 is in the closed mode, the air outlet 133 is connected to the outside, the first air outlet 803 is staggered with the air guide port 123, and the air outlet 804 is staggered with the air guide port 123;

[0150] Combination Fig.13 , Figure 15 to Figure 16 to Fig.17 and Figure 18 to Figure 19 to Fig. 20When the use mode of the adjustment cover 8 needs to be switched from the closed mode to the open mode, the third motor 91 is started, the third motor 91 drives the gear 92 to rotate, the gear 92 drives the toothed ring 93, and the toothed ring 93 drives the adjustment cover 8 to rotate around the first connection cover 12, the mounting frame 11 and the second connection cover 13;

[0151] When the adjusting cover 8 rotates, the adjusting cover 8 drives the air inlet 802 to rotate counterclockwise (such as Fig.15 The adjusting cover 8 is rotated in the direction shown in the figure, so that the adjusting cover 8 completely blocks the outside of the air outlet 133, so that the air outlet 133 is connected with the air inlet 802, and the hot air after heat exchange can be transported toward the inside of the air inlet 802 through the air outlet 133 and flow into the hollow structure of the adjusting cover 8;

[0152] When the adjustment cover 8 rotates, the adjustment cover 8 also drives the first air outlet 803 and the exhaust port 804 to rotate synchronously, so that the first air outlet 803 is connected with one of the drainage ports 123, and the exhaust port 804 is connected with another of the drainage ports 123, so that hot air is blown out through the first air outlet 803, and the isolation cover 14 and the lens module 3 are blown, demisted, cleaned and maintained, and the cleaned airflow carries the dried mist and is discharged through the other of the drainage ports 123 and the exhaust port 804;

[0153] While the first air outlet 803 is blowing air, the second air outlet 805 is simultaneously blowing air to remove mist and dust from the outside of the isolation cover 14;

[0154] like Fig.17 and Fig. 20 As shown, when the adjustment cover 8 is in the open mode, the air outlet 133 is connected to the outside, the first air outlet 803 and the air guide port 123 are staggered, and the exhaust port 804 and the air guide port 123 are staggered.

[0155] Finally, the control mainboard 2 and the lens module 3 are cooled by air blowing, and the lens end of the lens module 3 and the inner side of the isolation cover 14 are demisted and cleaned by air blowing after heat exchange.
