For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0025] The present invention provides a high efficiency catalyst filter. Figure 1-4As shown, it includes a filter body 1, a connecting component 2, a filter component 3 and a stopper 4; the connecting component 2 includes a first pipe 21, a first flange 22, a second pipe 23, a second flange 24 and a fifth flange 25; one end of the first pipe 21 is connected to the outer side surface of the filter body 1, and the other end of the first pipe 21 is connected to the first flange 22; the first flange 22 is connected to the catalyst dispersion tank; one end of the second pipe 23 is connected to the second flange 24, and the other end of the second pipe 23 is connected to the fifth flange 25, and the fifth flange 25 is connected to the catalyst dispersion tank; the filter component 3 is tiltedly arranged on the outer side surface of the filter body 1, and the filter component 3 is configured to communicate with the interior of the filter body 1, and the other end of the filter component 3 is connected to the second flange 24; the stopper 4 is arranged in the filter body 1, and the stopper 4 abuts against the filter component 3.

[0026] For example, the catalyst used in this application is a mixed catalyst of ZN118 and domestic CS-2-G, and the catalyst is a fine particle type.

[0027] Exemplarily, one end of the first pipe 21 is connected to the outer side of the filter body 1 , and the first pipe 21 is connected to the inner channel of the filter body 1 .

[0028] Exemplarily, the filter body 1 can be connected to the catalyst dispersion tank via the first pipe 21 and the first flange 22, allowing the filter body 1 to operate in the catalyst dispersion tank. The second pipe 23 can be connected to the catalyst dispersion tank via the fifth flange 25. The filter body 1 is also provided with a filter assembly 3 on the outer side, which is in communication with the interior of the filter body 1. The filter body 1 is provided with a stopper 4, which abuts the filter assembly 3, thereby connecting the interior of the filter body 1 with the interior of the filter assembly 3. The filter assembly 3 is connected to the second pipe 23 via the second flange 24, and the second pipe 23 is connected to the catalyst dispersion tank via the fifth flange 25. In other words, the filter body 1 is connected to the catalyst dispersion tank via the filter assembly 3 and the second pipe 23. This forms a passage from the catalyst body to the catalyst dispersion tank. Furthermore, the stopper 4 is provided inside the filter body 1 and abuts the filter assembly 3. When the catalyst enters the internal passage of the filter body 1, the close abutment between the stopper 4 and the filter assembly 3 enables the catalyst to be effectively filtered in the internal passage of the filter body 1.

[0029] In the embodiment of this application, Figure 1-4As shown, the filter assembly 3 includes a filter element 31, a sleeve 32 and a third flange 33; the filter element 31 is arranged in the sleeve 32, and the third flange 33 is connected to the end of the sleeve 32 away from the filter body 1; the sleeve 32 is obliquely arranged on the outer side of the filter body 1, and the sleeve 32 is configured to communicate with the interior of the filter body 1; the filter element 31 abuts against the block 4; the third flange 33 is connected to the second flange 24.

[0030] Exemplarily, the filter element 31 can filter the catalyst, and the sleeve 32 is fixedly connected to the outer side of the filter body 1 by threads. The sleeve 32 is configured to communicate with the interior of the filter body 1, and the sleeve 32 is tilted to the outer side of the filter body 1 at an angle of about 45°. The filter element 31 is arranged in the sleeve 32, so that the filter element 31 can filter the catalyst in the filter body 1.

[0031] Furthermore, the filter element 31 abuts against the block 4 , which is arranged inside the filter body 1 , and can position the filter element 31 and make the filter element 31 completely compact the filter, ensuring that the catalyst can be completely filtered through the filter element 31 .

[0032] In the embodiment of this application, Figure 3 As shown, the filter element 31 is provided with a plurality of filter holes 311 , which are evenly distributed on the outer wall of the filter element 31 , and the diameter of the filter holes 311 is 1.5 mm.

[0033] Exemplarily, the distance between the plurality of filter holes 311 is set to 2.5 mm.

[0034] In the embodiment of this application, Figure 3 As shown, the inner diameter of the filter element 31 is set to 49 mm.

[0035] In the embodiment of this application, Figure 3 As shown, the length of the filter element 31 is set to 133 mm.

[0036] For example, the specification of the filter element 31 is changed from the traditional 49 mm×131 mm×1 mm to 49 mm×133 mm×1.5 mm.

[0037] In the embodiment of this application, Figure 3 and Figure 4 As shown, the filter assembly 3 further includes two pads 35 ; the two pads 35 are respectively disposed at both ends of the filter element 31 .

[0038] Exemplarily, the pad 35 is made of polytetrafluoroethylene, which has the characteristics of high temperature resistance, chemical corrosion resistance, and insulation, and can ensure the service life of the pad 35.

[0039] In the embodiment of this application, Figure 2-4As shown, the gasket 35 includes a first mounting portion 351 and a second mounting portion 352; the outer diameter of the first mounting portion 351 is larger than the outer diameter of the second mounting portion 352; the first mounting portion 351 is fixedly connected to the second mounting portion 352; the second mounting portion 352 is arranged in the filter element 31, and the end of the first mounting portion 351 away from the filter element 31 abuts against the stopper 4.

[0040] Illustratively, the second mounting portion 352 is provided with a chamfer to facilitate replacement and installation of the filter element 31 .

[0041] For example, the gasket 35 close to the side of the filter body 1 will be blocked by the block 4, and the gasket 35 close to the side of the second pipe 23 will abut against the second flange 24. The filter element 31 can be stably installed between the second flange 24 and the block 4, thereby avoiding the formation of a gap between the filter element 31 and the filter body 1.

[0042] In the embodiment of this application, Figure 1 As shown, the filter body 1 includes two fourth flanges 11 ; the two fourth flanges 11 are respectively connected to both ends of the filter body 1 .

[0043] In the embodiment of this application, Figure 2 As shown, the stopper 4 is provided with an inclined surface 41 , which is parallel to the end surface of the cushion block 35 , and the cushion block 35 abuts against the inclined surface 41 .

[0044] For example, since the filter element 31 and the filter body 1 have a certain inclination angle, when positioning the filter body 1, it is necessary to set a plane that cooperates with the gasket 35 on the block 4 to ensure that the filter element 31 can be stably installed between the second flange 24 and the block 4, thereby avoiding the generation of a gap between the filter element 31 and the filter body 1.

[0045] In the embodiment of this application, Figure 1 As shown, the filter body 1 further includes a nameplate 5 , which is arranged on the outside of the filter body 1 .

[0046] The embodiment of the present utility model provides a high-efficiency catalyst filter, and the replacement process of the filter element 31 is as follows:

[0047] First, disassemble the second flange 24 and the third flange 33 by tightening the bolts. After disassembly, remove the old filter element 31 from the filter body 1; then, install gaskets 35 at both ends of the new filter element 31. After the gaskets 35 and the filter element 31 are installed, insert the installed filter element 31 into the sleeve 32 from the third flange 33; finally, fix the second flange 24 and the third flange 33 with bolts. After installation, the second flange 24 will support the gasket 35, and the other gasket 35 will be supported by the block 4 at the same time, so that the filter element 31 can be stably installed between the second flange 24 and the block 4, avoiding the formation of a gap between the filter element 31 and the filter body 1.

[0048] It should be noted that the specifications of the filter element 31 are changed from the traditional 49mm×131mm×1mm to 49mm×133mm×1.5mm, which makes the filtering effect of the irregular granular paste catalyst better, thereby avoiding the situation where the irregular granular paste catalyst causes pipeline obstruction or even blockage, ensuring the stability during filtration, and can reduce the frequency of replacing the filter element 31, thereby improving work efficiency.

[0049] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0050] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
