[0025] As Figure 1 and Figure 2 As shown in the figure, a pipeline filtering device for chemical engineering design, comprising an inlet pipe 1, characterized in that: one end of the inlet pipe 1 is externally sleeved with a transition pipe 11, the inside of the transition pipe 11 is provided with a filter structure 2 which is spatially perpendicular to and communicates with the inlet pipe 1, the filter structure 2 comprises a filter shell 21 placed on the inlet pipe 1, the inside of the filter shell 21 is connected with a plurality of uniformly distributed filter cores 23 through connecting rods 22, the upper part of the transition pipe 11 is connected with a corresponding cover 12 through fixing bolts, the side of the transition pipe 11 away from the inlet pipe 1 is provided with an overflow pipe 13 which communicates with itself, and the side of the transition pipe 11 away from the cover 12 is provided with an outlet pipe 14.

[0026] In this embodiment, the design of the filter housing 21 allows for quick access and replacement of the filter cartridge 23, greatly simplifying the maintenance process. The uniform distribution of the filter cartridge 23 ensures consistency in filtration efficiency while reducing resistance to fluid flow through the filter device. The design of the cover 12 takes into account the sealing, tightly connected with the transition pipe 11 by fixing bolts, preventing leakage that may occur under high pressure. The overflow pipe 13 provides additional safety for the filter device, which can automatically release pressure when the pressure in the filter housing 21 exceeds a certain threshold, avoiding damage to the equipment due to excessive pressure. The design of the water outlet pipe 14 allows the filtered clean fluid to flow smoothly to the downstream equipment, ensuring the continuity and stability of the chemical process. In addition, the overall structure of the filter device is compact, easy to install in the existing chemical pipeline system, without the need for large-scale modification of the existing system, with high practicality and economy.

[0028] In this embodiment, the design of the arc-shaped pipe body makes the connection between the inlet pipe 1 and the transition pipe 11 smoother, reducing the resistance and turbulence of fluid flow, thereby improving the flow efficiency of the fluid. The setting of the sleeve ring 24 not only enhances the stability of the connection between the filter housing 21 and the inlet pipe 1, but also facilitates quick installation and disassembly of the filter housing 21, facilitating maintenance and cleaning.
