[0002] A thermal power plant is a power plant that absorbs the heat energy generated by coal combustion through water to form steam to drive the turbine to rotate, thereby driving the generator to rotate and generate electricity. Since water is recycled in a thermal power plant, in order to ensure the quality of boiler feed water, high-parameter and large-capacity generator sets need to be equipped with condensate polishing and desalination equipment. By adding anion / cation resins to the condensate polishing and desalination equipment for water treatment, water waste can be reduced and costs can be saved. The resin in vitro regeneration system regenerates the adsorption saturated resin.

[0029] Please refer to Figure 1 , Figure 2 as well as Figure 6 In order to solve the problem that the resin is easily extracted from the regeneration tower 2000, the utility model proposes a filter element 1000, comprising:

[0030] The core body 1 has a peripheral wall formed with a plurality of filter gaps 11 , each filter gap 11 is used to allow water in the regeneration tower 2000 to flow into the core body 1 to be extracted from the regeneration tower 2000 ; the filter element 1000 is used to connect the tower body 4 of the regeneration tower 2000 .

[0031] In the technical solution of the present utility model, the resin will be blocked by the peripheral wall of the core 1 and remain on the outer wall of the core 1, and then be shuffled and regenerated in the regeneration tower 2000, while the water in the regeneration tower 2000 will flow into the core 1 from the filter gap 11 and be extracted. In this way, the separation of water and resin is achieved, and the resin is filtered so that the resin can be retained in the regeneration tower 2000, that is, the probability of the resin being extracted from the regeneration tower 2000 is reduced, saving resources.

[0032] Specifically, the core 1 is a filter cartridge 1a, and the filter gaps 11 are spaced apart on the peripheral wall of the filter cartridge 1a along the axial direction of the filter cartridge 1a; the peripheral edge of the cartridge mouth of the filter cartridge 1a is used to connect the tower body 4 of the regeneration tower 2000. The filter cartridge 1a is arranged in a cylindrical shape, so that the filter cartridge 1a has a stable structure and is not easily deformed; and the filter gaps 11 are provided on the peripheral wall of the filter cartridge 1a, and the width of the filter gaps 11 is not easily changed by external forces, so that the size of the resin that can be filtered is consistent, thereby facilitating the filtering of the resin.

[0033] Furthermore, the width of each filter gap 11 extending along the length direction of the core 1 is 0.25mm. Setting the width of each filter gap 11 to 0.25mm can not only filter the resin out of the water, but also screen the resin; the particle size of the damaged resin is less than 0.25mm, so it can also be drawn out of the regeneration tower 2000 with the water flow from the 0.25mm wide filter gap 11, while the particle size of the intact resin is greater than or equal to 0.25mm, so it cannot pass through the filter gap 11; in this way, the damaged resin is filtered out of the regeneration tower 2000 with the water flow, leaving only the intact resin for the next regeneration process, thereby improving the regeneration efficiency of the regeneration tower 2000.

[0034] Please refer to Figure 4 and Figure 5 In one embodiment, the core 1 includes a base 1b1, a winding wire and a plurality of winding posts 1b3, each winding post 1b3 is arranged on the base 1b1 and is distributed in a circumference, and the winding wire is spirally wound on the outer peripheral wall of each winding post 1b3; the winding wire forms a plurality of winding parts 1b21 arranged at intervals along the length direction of each winding post 1b3, and a filtering gap 11 is formed between two adjacent winding parts 1b21; and one end of each winding post 1b3 away from the base 1b1 is used to connect to the tower body 4 of the regeneration tower 2000. Such a setting can adjust the width of the filtering gap 11 by a special tool, so that the user can filter resins of different particle sizes according to actual production conditions, so that the filter element 1000 can be suitable for regeneration towers 2000 of different specifications.

[0035] In one embodiment, the filter element 1000 further includes a dredging assembly, which includes a dredging ring 31, and the inner peripheral wall of the dredging ring 31 is formed with bristles; the dredging ring 31 is movably connected to the mounting seat 2, and the core 1 is inserted into the dredging ring 31; the inner diameter of the dredging ring 31 is equal to the outer diameter of the core 1. The dredging ring 31 moves relative to the core 1, and the bristles on the inner peripheral wall of the dredging ring 31 clean the outer wall of the core 1, which can clean the resin blocked in the filter gap 11, so that the filter gap 11 is no longer blocked, thereby improving the filtering efficiency of the filter element 1000.

[0036] Specifically, the dredging ring 31 can be connected to the mounting base 2 through a telescopic rod 33, or can be connected to the mounting base 2 through a screw rod 35 and a screw rod nut 36. Figure 3 In one embodiment, the dredging assembly further includes a telescopic rod 33, which is disposed on the mounting seat 2, and a dredging ring 31 is disposed at one end of the telescopic rod 33 away from the mounting seat 2. The telescopic rod 33 is driven to extend and retract by the driving cylinder 32, so that the dredging ring 31 can move relative to the core body 1; thus, the outer wall of the core body 1 can be cleaned by the bristles on the inner wall of the dredging ring 31, and the resin blocked in the filter gap 11 can be cleaned, so that the filter gap 11 is no longer blocked, thereby improving the filtration efficiency of the filter element 1000. Please refer to Figure 1 In one embodiment, the dredging assembly further includes a driving motor 34, a screw 35 and a screw nut 36. The driving motor 34 is arranged on the mounting seat 2, the screw 35 is arranged on the output end of the driving motor 34, the screw nut 36 is connected to the screw 35, and the dredging ring 31 is arranged on the screw nut 36. The driving motor 34 drives the screw 35 to rotate and drives the screw nut 36 to reciprocate, so that the dredging ring 31 can move relative to the core body 1; the bristles on the inner wall of the dredging ring 31 clean the outer wall of the core body 1, and the resin blocked in the filter gap 11 can be cleaned, so that the filter gap 11 is no longer blocked, thereby improving the filtering efficiency of the filter element 1000.

[0037] In one embodiment, the dredging assembly further includes an infrared sensor, which is disposed on the inner wall of the core body 1 at one end close to the mounting seat 2, and the infrared sensor is electrically connected to the drive motor 34 through the single chip microcomputer. The infrared sensor is used to sense whether each filter gap 11 is blocked, and if blocked, a signal is sent to the single chip microcomputer, which controls the drive motor 34 to drive the screw rod 35 to rotate to drive the screw rod nut 36 to reciprocate, so that the dredging ring 31 can move relative to the core body 1 to clean the outer wall of the core body 1, thereby realizing automatic cleaning.

[0038] The utility model also proposes a regeneration tower 2000, which includes a filter element 1000. The specific structure of the filter element 1000 refers to the above embodiment. Since the regeneration tower 2000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0039] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
