Description

Technical Field

[0001] This utility model relates to the field of gas filtration technology, specifically to a gas filter with a filter element that can be cleaned without disassembly. Background Technology

[0002] Gas filters are widely used in natural gas processing, petrochemicals, city gas, and power energy to remove particulate matter, droplets, and other impurities from gas, ensuring the safe operation of equipment. With the continuous expansion of urban gas usage, the safe and efficient operation of gas supply systems is becoming increasingly important. However, in practical applications, traditional gas filters suffer from numerous problems, such as easy clogging of the filter element, frequent maintenance, and a decline in filtration efficiency over time, severely impacting the normal operation and production efficiency of gas equipment. Furthermore, traditional filters require frequent shutdowns and opening of the filter cover during cleaning, increasing manual cleaning costs, posing safety risks, and failing to meet the requirements of modern production for automation, intelligence, and environmental protection. Utility Model Content

[0003] To address the technical problems in existing technologies, such as the need for frequent shutdowns and cleaning of filter elements, which affects production continuity; the high cost of manual cleaning and the requirement for special equipment operation certificates, which poses safety risks, this utility model provides a gas filter with a filter element that can be cleaned without disassembly.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A gas filter with a filter element that does not require disassembly for cleaning includes a steam generator, a first valve, a filter body, and a filter element disposed inside the filter body. The filter body is also provided with a nozzle, a drain hole, and a drain valve connected to the drain hole. The steam output port of the steam generator is connected to one end of the first valve, and the other end of the first valve is connected to the nozzle. The nozzle is used to spray the steam output by the steam generator onto the filter element when the first valve is opened.

[0005] The beneficial effects of this invention are as follows: By installing nozzles inside the filter element and connecting the steam generator to the nozzles via a first valve, when cleaning the filter element is required, the valves supplying gas to the inlet and outlet of the gas filter in the gas supply system are closed, and the drain valve is opened, allowing the high-pressure steam output from the steam generator to be sprayed onto the filter element through the nozzles. The cleaned dirt is then discharged through the drain valve, thus achieving the cleaning of the filter element. This invention allows for steam cleaning of the filter element without disassembling it, solving the problem of frequent shutdowns and opening of the filter cover for cleaning, improving production efficiency, and reducing cleaning costs and operational risks.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, it also includes a gas storage tank, the inlet of which is connected to the steam outlet of the steam generator, and the outlet of which is connected to one end of the first valve.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by setting up an air storage tank, steam can be stored in the air storage tank, and the steam pressure can also be increased by using the air storage tank, so as to improve the cleaning efficiency of the filter element.

[0009] Furthermore, the nozzle includes multiple spray pipes located inside the central hole of the filter element, and each spray pipe has multiple spray holes, with each spray hole facing the inner wall of the central hole of the filter element.

[0010] The advantage of adopting the above-mentioned further solution is that by setting multiple spray pipes, the filter element can be sprayed and cleaned from multiple directions, thereby improving the cleaning quality.

[0011] Furthermore, the plurality of spray pipes are evenly distributed circumferentially along the central hole of the filter element.

[0012] The advantage of adopting the above-mentioned further solution is that multiple spray pipes are evenly distributed along the inner wall, which allows the spray cleaning to cover the entire inner wall of the filter element, thereby further improving the cleaning efficiency.

[0013] Furthermore, among the multiple spray holes on each of the spray pipes, the orifices of two adjacent spray holes face different directions.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, since the orifices of two adjacent spray holes are oriented differently, the spray cleaning range of a single spray pipe can be increased, making the spray cleaning more thorough.

[0015] Furthermore, the nozzle includes a spray pipe located inside the central hole of the filter element, and the spray pipe has multiple spray holes, each of which faces the inner wall of the central hole of the filter element.

[0016] The beneficial effect of adopting the above-mentioned further solution is that when the central hole of the filter element is too small to accommodate multiple spray pipes, a single spray pipe can be used with multiple holes to achieve comprehensive cleaning of the filter element.

[0017] Furthermore, the multiple spray holes are divided into multiple groups, each group of spray holes includes multiple spray holes, the multiple groups of spray holes are distributed at intervals along the axial direction of the spray pipe, and the multiple spray holes in each group are evenly distributed along the circumference of the spray pipe.

[0018] The beneficial effect of adopting the above-mentioned further solution is that multiple spray holes are distributed in both the axial and circumferential directions of a single spray pipe, which enables more comprehensive and thorough spray cleaning.

[0019] Furthermore, it also includes an intelligent differential pressure transmitter, one end of which is connected to the air inlet of the filter body, and the other end of which is connected to the air outlet of the filter body.

[0020] The beneficial effect of adopting the above-mentioned further solution is that, by setting up an intelligent differential pressure transmitter, the pressure difference between the gas filter inlet and outlet can be automatically adjusted to ensure the normal supply of gas.

[0021] Furthermore, it also includes a second valve and a third valve. One end of the second valve is connected to the air inlet of the filter body, and the other end of the second valve is connected to one end of the intelligent differential pressure transmitter. One end of the third valve is connected to the air outlet of the filter body, and the other end of the third valve is connected to the other end of the intelligent differential pressure transmitter.

[0022] The beneficial effect of adopting the above-mentioned further solution is that, by setting the second valve and the third valve, the air pressure detection on both sides of the intelligent differential pressure transmitter can be controlled by opening and closing the second valve and the third valve.

[0023] Furthermore, it also includes a fourth valve, one end of which is connected to the air outlet of the filter body, the other end of which is connected to one end of the drain valve, and the other end of the drain valve is connected to the drain hole.

[0024] The advantage of adopting the above-mentioned further solution is that, by setting a fourth valve, the gas outlet of the gas filter can be manually depressurized through the fourth valve. Attached Figure Description

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] like Figure 1 As shown, this embodiment provides a gas filter with a filter element that does not require disassembly for cleaning. It includes a steam generator 1, a gas storage tank 2, a first valve 3, a filter body 4, and a filter element 5 disposed inside the filter body 4. The filter body 4 also has a nozzle 6, and a drain hole 14 at its bottom. A drain valve 15 is connected to the drain hole 14, and the drain hole 14 and drain valve 15 are connected via a pipe. The steam output port of the steam generator 1 is connected to the inlet of the gas storage tank 2 via a pipe, and the outlet of the gas storage tank 2 is connected to one end of the first valve 3 via a pipe. The other end of the first valve 3 is connected to the nozzle 6 via a pipe. The nozzle 6 is used to spray steam output by the steam generator 1 onto the filter element 5 when the first valve 3 is open. The filter element 5 is fixed inside the filter body 4 by a filter element bracket. The top opening of the filter body 4 is sealed with a cap 7, which is connected to the filter body 4 via a flange to improve its sealing performance. By setting up the air storage tank 2, steam can be stored in the air storage tank 2, and the steam pressure can also be increased by the air storage tank 2, so as to improve the cleaning efficiency of the filter element 5.

[0029] In some embodiments, the gas filter further includes a smart differential pressure transmitter 8. One end of the smart differential pressure transmitter 8 is connected to the air inlet of the filter body 4, and the other end of the smart differential pressure transmitter 8 is connected to the air outlet of the filter body 4. By setting the smart differential pressure transmitter 8, the pressure difference between the air inlet and outlet of the gas filter can be automatically adjusted to ensure a normal gas supply. It should be noted that the smart differential pressure transmitter 8 is a commonly used device on the market and can be purchased directly.

[0030] In some embodiments, the gas filter further includes an inlet pipe 11, an outlet pipe 12, a second valve 9, and a third valve 10. One end of the inlet pipe 11 is fixedly disposed at the inlet of the filter body 4 and connected to the inlet. One end of the outlet pipe 12 is fixedly disposed at the outlet of the filter body 4 and connected to the outlet. One end of the second valve 9 is connected to the inlet pipe 11, and the other end of the second valve 9 is connected to one end of the intelligent differential pressure transmitter 8. One end of the third valve 10 is connected to the outlet pipe 12, and the other end of the third valve 10 is connected to the other end of the intelligent differential pressure transmitter 8. The other end of the inlet pipe 11 is used to connect to an upstream gas pipeline, and the other end of the outlet pipe 12 is used to connect to a downstream gas pipeline. By setting the second valve 9 and the third valve 10, the gas pressure detection on both sides of the intelligent differential pressure transmitter 8 can be controlled by opening and closing the second valve 9 and the third valve 10.

[0031] In some embodiments, the gas filter further includes a fourth valve 13, one end of which is connected to the gas outlet of the filter body 4, and the other end of which is connected to one end of a vent valve 15, the other end of which is connected to a vent hole 14. By providing the fourth valve 13, the gas outlet of the gas filter can be manually depressurized.

[0032] This invention, through the installation of a nozzle 6 within the filter element 5 and the connection of a steam generator 1 to the nozzle 6 via a first valve 3, allows for thorough cleaning of the filter element 5. When cleaning is required, the valves supplying gas to the inlet and outlet of the gas filter in the gas supply system are closed, and the drain valve 15 is opened. This allows the high-pressure steam output from the steam generator 1 to be sprayed onto the filter element 5 through the nozzle 6, and the cleaned dirt is discharged through the drain valve 15. This invention eliminates the need to disassemble the filter element 5, enabling steam cleaning and solving the problem of frequent shutdowns and opening of the filter cover for cleaning. This improves production efficiency and reduces cleaning costs and operational risks.

[0033] like Figure 2As shown, in some embodiments, the nozzle 6 includes a spray head 601, a fixed post 603, and multiple spray pipes 602. The multiple spray pipes 602 are located inside the central hole of the filter element 5, and each spray pipe 602 has multiple spray holes 604, each spray hole 604 facing the inner wall of the central hole of the filter element 5. By setting multiple spray pipes 602, the filter element 5 can be sprayed and cleaned from multiple directions, thereby improving the cleaning quality. A first steam inlet hole is provided at the top of the spray head 601, and the steam inlet hole is equipped with a steam connecting pipe, which is integrally formed with or welded to the spray head 601. A second steam inlet hole is provided at the bottom of the nozzle 601. The diameter of the second steam inlet hole is larger than that of the first steam inlet hole. A sealing plate is provided at the bottom of the nozzle 601 to seal the second steam inlet hole. The sealing plate is connected to the flange of the nozzle 601. The sealing plate has multiple threaded holes, each of which communicates with the second steam inlet hole. The upper end of the spray pipe 602 has an external thread. The external thread at the upper end of the spray pipe 602 is threaded to match the threaded hole on the sealing plate, thereby achieving a fixed connection between the spray pipe 602 and the sealing plate. High-pressure steam enters the spray pipe 602 sequentially through the first steam inlet hole and the second steam inlet hole. It should be noted that the bottom end of the spray pipe 602 is sealed to ensure that the high-pressure steam is sprayed out from the spray hole 604 of the spray pipe 602. During installation, try to make the center line of the spray pipe 602 parallel to the center line of the center hole of the filter element 5. The top of the fixing post 603 is fixedly connected to the sealing disc or via a threaded connection. The spray head 601 is fixedly connected to the top of the filter element 5 via a filter element bracket. The bottom of the fixing post 603 is connected to the bottom of the filter element 5 via the filter element bracket. Specifically, an insertion hole can be made on the filter element bracket at the bottom of the filter element 5, allowing the bottom of the fixing post 603 to be inserted and matched with the insertion hole. Multiple spray pipes 602 are evenly distributed along the inner wall of the central hole of the filter element 5. The even circumferential distribution of multiple spray pipes 602 along the inner wall allows the spray cleaning to cover the entire inner wall of the filter element 5, further improving cleaning efficiency.

[0034] like Figure 3 As shown, in some embodiments, the nozzle 6 includes a spray head 601 and a spray pipe 602. The spray pipe 602 is located inside the central hole of the filter element 5, and multiple spray holes 604 are formed on the spray pipe 602, each spray hole 604 facing the inner wall of the central hole of the filter element 5. When there is only one spray pipe 602, there is only one threaded hole on the sealing plate. The threaded hole is located as close as possible to the center of the sealing plate. The top end of the spray pipe 602 is threadedly connected to the nozzle 6 and the sealing plate through the threaded hole. The bottom end of the spray pipe 602 is inserted and matched with the insertion hole. The spray pipe 602 is made of stainless steel to improve its rigidity. When the central hole of the filter element 5 is too small to accommodate multiple spray pipes 602, a single spray pipe can be used with multiple holes to achieve comprehensive cleaning of the filter element 5.

[0035] A central connecting steel pipe is welded to the side of the filter body 4. One end of the central connecting steel pipe is inserted into the filter body 4, and the other end of the central connecting steel pipe is located outside the filter body 4. The outer circle of the central connecting steel pipe is welded to the filter body 4. One end of the central connecting steel pipe is connected to the first steam inlet hole through a pipe, and the other end of the central connecting steel pipe is connected to the other end of the first valve 3 through a pipe.

[0036] like Figure 4 As shown, when the number of spray pipes 602 is 3, the 3 spray pipes 602 are evenly distributed around the fixed column 603.

[0037] like Figure 5 As shown, when the number of spray pipes 602 is 6, the 6 spray pipes 602 are evenly distributed around the fixed column 603.

[0038] like Figure 6 As shown, when there are multiple spray pipes 602, the orifices of adjacent spray holes 604 on each spray pipe 602 have different orientations. The centerlines of two adjacent spray holes 604 do not intersect, and after the centerlines of two adjacent spray holes 604 are projected onto the same projection plane, the included angle between the projections of the centerlines of the two adjacent spray holes 604 on the projection plane is 30° to 60°. Because the orifices of two adjacent spray holes 604 have different orientations, the spray cleaning range of a single spray pipe 602 can be increased, making the spray cleaning more thorough.

[0039] like Figure 7 As shown, when there is only one spray pipe 602, the spray pipe 602 is provided with multiple spray holes 604. The multiple spray holes 604 are divided into multiple groups, and each group of spray holes 604 includes multiple spray holes 604. The multiple groups of spray holes 604 are distributed at intervals along the axial direction of the spray pipe 602, and the spacing between adjacent groups of spray holes 604 is the same. The multiple spray holes 604 in each group of spray holes 604 are evenly distributed along the circumference of the spray pipe 602. The distribution of multiple spray holes 604 in both the axial and circumferential directions of a single spray pipe 602 allows for more comprehensive and thorough spray cleaning.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the concept and principles of the present utility model should be included within the protection scope of the present utility model.
