Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a filtering device and a water treatment system. Background Art

[0002] As one of the most critical equipment in the water treatment system, the filter is widely used in various fields, such as industrial production, environmental protection, medical and health care, etc. The filter is mainly used to purify water in water treatment, that is, the filter physically filters the water, and the impurities in the water are trapped on the filter medium to remove impurities and suspended matter in the water. These impurities may include particulate matter, organic matter, microorganisms, etc., and the filtered water flows out through the filter. If the filtering performance of the filter is not good, it may cause the filtered water quality to be substandard. The water is not effectively purified before entering the subsequent equipment, resulting in impurities in the water that will damage the subsequent equipment or affect the product quality, thereby shortening the service life of the equipment and the product failing to meet the requirements. Therefore, the filtering performance of the filter is crucial. In the related art, a cylindrical filter is usually used, which is rolled and welded by carbon steel or stainless steel plates, and the top and bottom adopt a head structure, which has good filtering performance.

[0003] However, the filtering performance of the filter is affected by the filtering area. The actual filtering area of ​​the cylindrical filter is relatively small. If the filtering area is to be expanded, the overall size of the filter will also increase accordingly. In addition, when the cylindrical filter is integrated into a complete water treatment system, due to structural reasons, its floor space and overall size are too large, resulting in poor integration and compactness. Therefore, how to increase the filtering area of ​​the filter and the compactness of the filter integrated into the water treatment system is a problem that needs to be solved urgently.

[0021] The first thing you need to understand is that the filter is a key device for water purification and treatment. It plays an irreplaceable and important role in water treatment and is widely used. For example, it is used in industrial production to reduce industrial water consumption and increase water reuse rate; it is used in agricultural production to implement scientific irrigation and reduce agricultural water waste; it is used in environmental protection to recycle urban sewage and open up a second water source. When the filter is working, the water to be filtered enters the filter from the water inlet. After being filtered through the filter material, some substances that are not necessary for production and life in the water are removed, and then it is discharged to the required pipes through the water outlet. Filtration area is one of the two important indicators for evaluating filter performance. It refers to the surface area inside the filter used for filtration, usually measured in square meters (m 2 ) is used as a unit. The size of the filtration area directly affects the filtration performance of the filter. A larger filtration area can accommodate more filter media, thereby being able to handle a larger flow rate or accommodate more impurities. At the same time, the larger the filtration area, the longer the service life of the filter will be, because it can accommodate more impurities and is not easy to clog. Therefore, for applications that need to process large amounts of water, it is usually necessary to select a filter with a larger filtration area.

[0022] At present, the filter used in water treatment is usually a cylindrical filter, and its main structural feature is that it is a steel cylindrical device as a whole, with a water inlet device, a water distribution device and a drainage device installed inside, and corresponding auxiliary equipment such as pipes, instruments and valves are also equipped on the outside. In addition, the top and bottom of the filter are equipped with a head structure to prevent leakage of the filter medium and provide connection with pipes or equipment. The main application areas of cylindrical filters include pretreatment processes such as reverse osmosis, electrodialysis, ion exchange and softening desalination systems. It can also be used in industrial water supply coarse filtration, circulating cooling water, and sewage and reclaimed water reuse treatment processes. However, the cylindrical filter has the disadvantage of a small actual filtration area. If the filtration area is to be expanded, the overall size of the filter will also increase accordingly. The filter has a large footprint when assembled into a complete set of units, and the integration and compactness in the water treatment system are low; in addition, when the cylindrical filter is integrated into a complete set of water treatment systems, due to structural reasons, its footprint and overall size are too large, and there are problems of poor integration and compactness. To solve the above problems, the present application provides a filtering device and a water treatment system.

[0023] See also Figure 1 , is a schematic diagram of the structure of a filter device according to an exemplary embodiment of the present invention. The exemplary embodiment provides a filter device, which at least comprises: Figure 1 The rectangular body shown has a flat top design on the top and a flat bottom design on the bottom; water distributors are respectively provided at the top and bottom inside the rectangular body; filter material is filled in the rectangular body, and the filter material is distributed between the two water distributors; a water inlet A is provided on the side surface of the top of the rectangular body, and the water inlet A is connected to the water distributor at the top; a water outlet B is provided at the bottom of the rectangular body, and the water outlet B is connected to the water distributor at the bottom.

[0024] In one embodiment, the water inlet of the filtering device is an interface for supplying water to be filtered to the filtering device, and is the entrance for water to enter the filter; the water outlet is an interface for discharging filtered water from the filtering device, and is the outlet for filtered water to flow out of the filtering device; the water distributor at the bottom is used to distribute water evenly and stably to the entire bottom area of ​​the filter to achieve a uniform filtration process and prevent certain areas from having poor filtration effects or premature clogging due to excessive or insufficient water flow; the water distributor at the top is used to evenly flow water to the filter material, which helps to improve the filtration efficiency. At the same time, the water distributor at the top can also prevent the water flow from directly impacting the filter material, thereby protecting the shape of the filter material from damage.

[0025] In one embodiment, the water to be filtered enters the rectangular body through the water inlet A, and then is evenly distributed in the filter material through the water distributor at the top, filtered by the filter material, and finally the filtered water flows to the water outlet B through the water distributor at the bottom and is sent out of the filter device. The filter device is a square structure, that is, similar to a rectangular box. In this way, in the water treatment system, not only is the space occupied small, the integration and compactness are high, but also the filter area and the filter capacity are larger, which improves the filter efficiency of the filter device. In addition, the filter device adopts a flat top and a flat bottom setting, that is, the top and bottom of the filter device are both flat, without concave or protruding parts, which reduces the overall height of the filter device, further reduces the volume and size of the filter device, and the space utilization rate of the filter is high.

[0026] Specifically, the water distributor is a woven screen tube with a cross structure, and a partition is provided inside the rectangular body. The partition is located between the filter material and the water distributor at the bottom and is used to support the filter material so that the filter material is distributed between the two water distributors.

[0027] In one embodiment, when the water distributor is a braided screen tube, the structure of the braided screen tube is as follows: Figure 1The cross structure D shown is arranged at the top and the space at the top of the rectangular body, and the water inlet and the braided screen tube at the top, and the water outlet and the braided screen tube at the bottom are all connected through pipes. In addition, since the filter device is a square structure, the filter material as the filter layer also has a rectangular surface. Therefore, in order to ensure the uniform distribution of water in the filter device and improve the filtering efficiency, a braided screen tube with a cross-shaped cross structure is used. The water flow to be filtered enters the braided screen tube, and the water is distributed in a cross-shaped area, so that the water flow is evenly distributed to all areas of the filter material.

[0028] Specifically, the water distributor is a porous plate, and the through holes on the porous plate are equipped with water caps.

[0029] In one embodiment, when the water distributor is a porous plate, the position of the filter material is directly limited by the top and bottom porous plates, so that the filter material is distributed between the two porous plates. The bottom porous plate is often used as a supporting structure to fix and support the filter material inside the filter device, ensuring that the filter material maintains the correct position inside the filter to prevent it from moving or deforming; the top porous plate mainly plays the role of filtering and separation, usually located above the filter element, and intercepts and captures solid particles or impurities in the water through its through-hole structure. The size and arrangement shape of these holes can be customized according to the filtering requirements, so that the water can be evenly distributed on the entire porous plate and flow to the filter material through the through-holes, achieving uniform distribution of water in the filter device, thereby improving the performance and reliability of the filtering equipment.

[0030] In one embodiment, the number of water caps is set based on the filtered water flow rate, that is, the through holes of the porous plate are set according to the water flow rate, so that the water flow can flow smoothly through the filter device, which helps to reduce the impact of the water flow on the filter material.

[0031] Specifically, a loading port E is arranged on the top of the rectangular body, and a discharging port F is arranged on the bottom side.

[0032] In one embodiment, the discharge port is used to add filter material to the filter device or replace old filter material, to discharge old filter material from the filter device, and to discharge impurities accumulated after filtration. These impurities may include trapped suspended matter, particulate matter, and microorganisms. When the impurities accumulate to a certain extent, they need to be discharged through the discharge port to maintain the filtration efficiency of the filter device.

[0033] In one embodiment, the water inlet A and the discharge port F are located on the same side to ensure the convenience and compactness of the external pipeline connection of the filtering device.

[0034] Specifically, a side exhaust port C is provided at the bottom of the rectangular body, and the side exhaust port C is connected to a valve.

[0035] In one embodiment, the side drain port and the valve are used in conjunction. The side drain port is used to discharge impurities, residues or accumulated water inside the filter, which helps to maintain the cleanliness and filtering performance of the filtering device and prevent impurities from interfering with the filtering process. The valve can control the discharge rate of the side drain port, which helps to avoid excessive or insufficient pressure inside the filtering device, thereby protecting the filtering device from damage.

[0036] In one embodiment, the rectangular body is made of any one of glass fiber reinforced plastics, carbon steel and stainless steel.

[0037] Specifically, an anti-corrosion layer is provided on the inner wall of the rectangular body.

[0038] In one embodiment, if corrosion occurs inside the filter device, it may cause damage to the filter material, water distributor and other components inside the filter device. On the one hand, the filtering effect is reduced, and impurities and particulate matter in the medium cannot be effectively removed, thereby affecting the normal operation of the filter device and reducing the overall filtering efficiency; on the other hand, the damage and replacement frequency of various components inside the filter increase, thereby increasing the maintenance cost of the filter device, and in extreme cases, the filter may rupture due to corrosion, which may cause safety accidents. Therefore, an anti-corrosion layer is applied to the inner wall of the rectangular body to isolate corrosive substances such as chloride ions and sulfate ions that may be contained in the water. These ions come into contact with the internal materials of the filter to prevent corrosion.

[0039] An embodiment of the utility model further provides a water treatment system, which integrates the filtering device provided in each of the above embodiments.

[0040] Based on the above embodiments, the present application proposes a filter device and a water treatment system having the following characteristics: First, the filter device as a whole presents a square structure. Compared with a filter device with a cylindrical structure of the same volume, its filter area is larger. Without increasing the space occupied by the filter device, the filter efficiency is effectively improved, and the rectangular structure is conducive to integration. The filter device is integrated into the water treatment system with high compactness; Second, the filter device adopts a flat bottom and a flat top setting, which is compared with the cylindrical filter device with a head structure at the top and bottom, which can effectively reduce the overall height of the filter device, improve the space utilization of the filter device, and further enhance the compactness of the filter device integrated into the water treatment system; Third, the filter device has a simple structure and low manufacturing cost.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
