[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Combination Figures 1 to 3 The high-flow nuclear filter cartridge device for water and air filtration described in this embodiment includes a cylinder, an upper end cover 1 at the top of the cylinder with a through hole in the middle of the upper end cover 1, and a lower end plate 6 at the bottom of the cylinder; multiple inner hoop rings 3 are arranged sequentially from top to bottom on the inner side of the cylinder; and a filter screen 2 is arranged on the outer side of the cylinder.

[0029] In this example, three inner hoop rings are set, namely the first inner hoop ring, the second inner hoop ring, and the inner hoop ring. The outer diameter of the inner hoop ring is the same as the inner diameter of the cylinder. The three inner hoop rings are evenly distributed along the vertical direction of the cylinder. The three inner hoop rings inside strengthen the overall strength of the cylinder, enabling it to withstand the ultimate pressure difference greater than 1034 kPa under accident conditions.

[0030] The cylinder body has a cylindrical internal skeleton 5 with uniformly distributed through holes on the surface, and the opening rate can be greater than 42%.

[0031] In this example, the inner skeleton 5 has a thickness of 1.5 mm, a skeleton hole diameter of 5 mm, a hole center distance of 7 mm, and an opening ratio of up to 45%.

[0032] Multiple support feet 4 are evenly distributed along the circumference on the lower surface of the lower end plate 6.

[0033] In this example, there are 3 support feet. These three support feet 4 are evenly distributed along the circumference on the lower surface of the lower end plate to support the filter element.

[0034] This nuclear filter element is made of stainless steel and features a fully welded structure. It can withstand a pressure drop of up to 1034 kPa without breaking, maintaining structural integrity. It can withstand temperatures up to 62.7°C and is corrosion-resistant. The filtration accuracy is 15 microns, with a filtration efficiency of 100%, and the filtration direction is from the outside in. Typically, this example allows for a filtration accuracy range of 5 to 15 microns, depending on the specific requirements.

[0035] The folding height typically ranges from 7 to 20 mm, depending on the application requirements.

[0036] In this example, filter screen 2 is made of sintered stainless steel metal fiber filter media with a fold height of 8mm and a fold count of 100±2. Filter screen 2 has a backwashing and regeneration function, eliminating the need for complete filter element replacement and reducing waste volume.

[0037] When the filter element is used to filter water, the through hole in the middle of the upper end cap 1 serves as the water inlet. Particles and suspended impurities larger than or equal to 5-15 micrometers in the water and gas are intercepted on the surface of the sintered stainless steel fibers, thus achieving the water filtration and purification effect. When filtering water, the flow rate is greater than 182 L / min.

[0038] When the filter element of this nuclear reactor filters air, when air enters the cylinder through the through-holes in the filter screen, particles and suspended impurities larger than or equal to 5 to 15 micrometers in the gas are intercepted on the surface of the stainless steel sintered fiber, achieving the effect of filtration, interception and purification, and ensuring that the air is effectively filtered.

[0039] This utility model provides a concept for a high-flow-rate nuclear filter cartridge device for water and air filtration. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
