[0024] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0025] Reference below Figure 1-Figure 2 A gas filter according to an embodiment of the present application is described.

[0026] The gas filter 1 provided in the embodiment of the present application includes a device body 2 , a filter element 11 and an ultrasonic generator 12 .

[0027] The device body 2 has a filter cavity 8 and an exhaust cavity 9 which are connected to each other. The device body 2 is provided with an air inlet 3 which is connected to the filter cavity 8 and an air outlet 4 which is connected to the exhaust cavity 9 .

[0028] In this embodiment, the device body 2 is a container, and illustratively, the device body 2 can be a tank or a box, etc. The device body 2 is provided with a filter chamber 8 and an exhaust chamber 9 that are interconnected, the air inlet 3 passes the gas to be filtered into the filter chamber 8, and the air outlet 4 discharges and recycles the filtered gas in the exhaust chamber 9.

[0029] The filter element 11 is installed in the filter chamber 8 and is located at the connection point between the filter chamber 8 and the exhaust chamber 9. The device body 2 is also provided with a water inlet 5 and a water outlet 6 connected to the filter chamber 8. The water outlet 6 is provided at the lower end of the device body 2.

[0030] In this embodiment, the filter element 11 is installed in the filter chamber 8 and is located at the connection between the filter chamber 8 and the exhaust chamber 9, so that the gas to be filtered entering the filter chamber 8 needs to be filtered by the filter element 11 before entering the exhaust chamber 9. It can be understood that the gas passing through the filter element 11 and entering the exhaust chamber 9 is the clean gas after filtering. The water inlet 5 is connected to the filter chamber 8 to inject water into the filter chamber 8 through the water inlet 5 to clean the filter element 11 installed in the filter chamber 8. The water outlet 6 is connected to the filter chamber 8 to discharge the sewage from the gas filter 1 through the water outlet 6 after the filter element 11 is cleaned, which is convenient for subsequent gas filtering work.

[0031] The ultrasonic generator 12 is installed on the device body 2 and corresponds to the filter element 11 .

[0032] The ultrasonic generator 12 is installed on the device body 2. The ultrasonic generator 12 can emit ultrasonic waves to shake off the dirt adsorbed on the filter element 11 through the vibration caused by the ultrasonic waves, thereby achieving cleaning and regeneration of the filter element 11. The ultrasonic generator 12 is set corresponding to the filter element 11 to improve the effect of ultrasonic cleaning.

[0033] In actual implementation, after closing the air inlet 3, water is injected into the filter chamber 8 through the water inlet 5, and after the filter element 11 is immersed in water, the ultrasonic generator 12 is turned on to perform ultrasonic cleaning on the filter element 11. After cleaning, the water outlet 6 is opened to discharge the sewage. The cleaning is completed. The entire cleaning process does not require opening the gas filter 1 or disassembling the filter element 11, and the cleaning is convenient and efficient.

[0034] According to the gas filter 1 provided in the embodiment of the present application, a water inlet 5 and an ultrasonic generator 12 are arranged on the device body 2, water is injected into the filter chamber 8 equipped with the filter element 11 through the water inlet 5, and ultrasonic waves are emitted through the ultrasonic generator 12 corresponding to the filter element 11, so that ultrasonic cleaning of the filter element 11 is achieved without opening the gas filter 1 to remove the filter element 11, thereby facilitating cleaning, reducing the difficulty of cleaning the filter element 11, and improving cleaning efficiency.

[0035] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the filter chamber 8 and the exhaust chamber 9 can be distributed in the up-down direction, and the filter chamber 8 can be arranged at the lower side of the exhaust chamber 9, the filter element 11 can extend in the up-down direction, and the ultrasonic generator 12 can be installed on the side wall of the device body 2 and arranged in the up-down direction.

[0036] In this embodiment, the filter chamber 8 can be arranged at the lower side of the exhaust chamber 9, so that after water is injected into the filter chamber 8, the water is deposited in the filter chamber 8, and the impact on the exhaust chamber 9 is small. The filter element 11 is extended in the filter chamber 8 along the up and down directions to be better immersed in water. The ultrasonic generator 12 can be installed on the side wall of the device body 2, wherein the ultrasonic generator 12 can include a plurality of generating parts arranged in the filter chamber 8, and the plurality of generating parts are arranged on the inner side wall of the device body 2 and distributed along the up and down directions so that the ultrasonic generator 12 corresponds to the filter element 11 to improve the cleaning effect.

[0037] In some embodiments, the filter chamber 8 and the exhaust chamber 9 can be arranged in a horizontal direction, and a switchable seal is provided at the connection point between the filter chamber 8 and the exhaust chamber 9. When the filter element 11 is cleaned, the filter chamber 8 is sealed from the exhaust chamber 9 by the seal, so that the water is isolated in the filter chamber 8, thereby reducing the impact of the cleaning of the filter element 11 on the exhaust chamber 9.

[0038] It is understandable that the filter chamber 8 and the exhaust chamber 9 may also be arranged in other ways to adapt to various installation environments.

[0039] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the filter element 11 can be arranged in the middle of the filter chamber 8, and a flushing pipeline arranged around the filter element 11 can be provided in the filter chamber 8, the water inlet end of the flushing pipeline can be connected to the water inlet 5, and a plurality of water spray outlets arranged toward the filter element 11 can be provided on the flushing pipeline.

[0040] In this embodiment, the filter element 11 can be centrally arranged in the middle of the filter chamber 8, so that the filter element 11 is separated from the side wall of the device body 2. A flushing pipeline arranged around the filter element 11 can be provided in the filter chamber 8. The flushing pipeline can be installed on the side wall of the filter chamber 8. The water inlet end of the flushing pipeline can be connected to the water inlet 5 so that the water from the water inlet 5 enters the flushing pipeline first when entering the filter chamber 8, and then is sprayed out through the water spray port opened on the flushing pipeline. By setting the water spray port toward the filter element 11, flushing can be performed through the water spray port before ultrasonic cleaning, thereby improving the cleaning effect.

[0041] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, a liquid level gauge 13 may be provided at a position of the device body 2 corresponding to the filter cavity 8 .

[0042] In this embodiment, a liquid level meter 13 is provided to detect the liquid level height in the filter chamber 8, so that when the liquid level reaches a predetermined height, the water inlet 5 is controlled to be closed and water injection is stopped to prevent water from overflowing into the drainage chamber, and automatic control is facilitated to control the ultrasonic generator 12 to start when the liquid level reaches a predetermined height.

[0043] According to one embodiment of the present application, Figure 1 and Figure 2 As shown, the air inlet 3 can be arranged at the lower part of the filter cavity 8, and the air inlet 3 can be spaced apart from the lower end of the device body 2.

[0044] In this embodiment, the air inlet 3 can be arranged at the lower part of the filter chamber 8 to increase the air path between the air inlet 3 and the exhaust chamber 9 and improve the filtering effect. The air inlet 3 is spaced apart from the lower end of the device body 2 to facilitate water storage and drainage at the lower end of the filter chamber 8, and water is not easy to flow back into the air inlet 3.

[0045] According to one embodiment of the present application, Figure 1 and Figure 2As shown, the device body 2 may be provided with a hot air outlet 7 connected to the exhaust cavity 9 , and the hot air outlet 7 is used to introduce high-temperature gas into the device body 2 .

[0046] In this embodiment, the hot air outlet 7 can be connected to the exhaust chamber 9. After the hot air outlet 7 is opened, high-temperature gas can be rushed into the exhaust chamber 9 through the hot air outlet 7. The high-temperature gas enters the filter chamber 8 through the connection between the exhaust chamber 9 and the filter chamber 8 to dry the filter element 11 and the inner wall of the filter chamber 8 after ultrasonic cleaning, so as to facilitate the subsequent gas filtering work as soon as possible. In addition, the air pressure of the high-temperature gas can also be used to back-blow the filter element 11 in the reverse direction, thereby improving the regeneration rate of the filter element 11.

[0047] In actual implementation, after the ultrasonic cleaning is completed and the ultrasonic generator 12 is shut down, the water outlet 6 is opened to drain the water in the filter chamber 8, and then the hot air outlet 7 is opened to allow high-temperature gas to be passed into the exhaust chamber 9 and the filter chamber 8 for drying. The high-temperature gas is also discharged through the water outlet 6 to dry and back-blow the filter element 11 and the filter chamber 8. After the preset time, the drying is judged to be completed and the hot air outlet 7 is closed.

[0048] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, a partition plate 10 may be provided in the device body 2, and the partition plate 10 may be used to separate the filter chamber 8 and the exhaust chamber 9. A connecting hole connecting the exhaust chamber 9 and the filter chamber 8 may be provided on the partition plate 10, and the filter element 11 may be fixedly installed on the partition plate 10 and correspond to the connecting hole.

[0049] In this embodiment, by setting the partition plate 10, on the one hand, it plays the role of separating the filter chamber 8 and the exhaust chamber 9 to limit the gas path, and on the other hand, it plays the role of fixing and installing the filter element 11. The partition plate 10 is provided with a connecting hole that penetrates along the thickness direction, so that the exhaust chamber 9 and the filter chamber 8 are connected through the connecting hole. Exemplarily, when the filter chamber 8 and the exhaust chamber 9 are distributed in the up and down direction, the partition plate 10 is arranged in the horizontal direction, the upper end of the filter element 11 is fixedly connected to the partition plate 10, and the filter element 11 is installed at the position of the connecting hole correspondingly, so that the gas needs to be filtered by the filter element 11 before entering the connecting hole.

[0050] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the filter element 11 can be arranged in a hollow cylindrical shape, one end of the filter element 11 is fixedly connected to the partition plate 10, and the hollow part of the filter element 11 corresponds to the connecting hole.

[0051] In this embodiment, the filter element 11 can be arranged in a hollow cylindrical shape, so as to increase the filtering area of ​​the filter element 11, and the gas enters the hollow part of the filter element 11 through the side wall of the filter element 11 to achieve filtering, and by making the hollow part of the filter element 11 correspond to the communication hole, the filtered clean gas can enter the exhaust chamber 9 through the communication hole. The upper end of the filter element 11 can be fixedly connected to the partition plate 10 by bolts. It can be understood that the upper end of the filter element 11 is sealed with the peripheral side of the communication hole to improve the filtering effect.

[0052] In some embodiments, Figure 1 and Figure 2 As shown, the air inlet 3 can be arranged on the side wall of the device body 2, and the air inlet direction of the air inlet 3 is arranged to intersect with the extension direction of the filter element 11, thereby reducing the probability of the gas directly passing through the hollow part of the filter element 11 and entering the exhaust chamber 9 directly, so that most of the gas entering the filter chamber 8 through the air inlet 3 will be filtered by the filter element 11, thereby improving the filtering effect.

[0053] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, there may be a plurality of communicating holes, and the plurality of communicating holes may be distributed along the circumference of the partition plate 10 . There may be a plurality of filter elements 11 , and the plurality of filter elements 11 may correspond one-to-one to the plurality of communicating holes.

[0054] In this embodiment, multiple connecting holes and multiple filter elements 11 are provided to increase the total area of ​​the filter element 11, thereby improving the filtering effect and filtering efficiency. The multiple connecting holes are spaced apart from each other, and the multiple filter elements 11 are also spaced apart from each other to improve the filtering effect.

[0055] The number of filter elements 11 is not limited here, and can be two or more, determined according to design requirements. It is understandable that when there are multiple filter elements 11, the cleaning efficiency of the ultrasonic generator 12 in the present application can be improved.

[0056] According to some embodiments of the present application, a switch device may be provided on the partition plate 10, and the switch device may be used to control the opening and closing of the connecting hole.

[0057] In this embodiment, by arranging a switch device on the partition plate 10, when water is injected through the water inlet 5, the switch device can be remotely controlled to close the connecting hole to reduce the influence of water on the exhaust chamber 9, and automatic cleaning can be achieved. It should be noted that the body 2 can also be provided with an air hole, which is connected to the filter chamber 8 and is arranged at the upper part of the filter chamber 8, so that when the connecting hole is closed, the air hole is opened to avoid the influence of the sealing of the filter chamber 8 on the water injection.

[0058] In one example, the switch device may be a sealing plate, which can be opened and closed on the partition plate 10, and the sealing plate can cover the communication hole and seal the communication hole. In another example, the sealing plate can be attached to the partition plate 10 and can be rotatably arranged, and the communication hole is opened when it is rotated to a preset angle, and the sealing plate is closed and sealed when it is rotated to another preset angle.
