[0001] This utility model relates to the technical field of air separation equipment, and in particular to a cooling water circulation filtration device for air separation equipment. Background Technology

[0002] Air separation equipment is an important industrial device, mainly used to separate and purify components such as oxygen and nitrogen in the air. During the operation of air separation equipment, the circulation of cooling water is an essential link, and the quality of cooling water directly affects the operating efficiency and stability of air separation equipment. Traditional cooling water circulation systems often lack effective filtration devices, resulting in high impurity content in the cooling water. This not only affects the heat dissipation effect of air separation equipment, but may also cause corrosion and blockage inside the equipment, reducing its service life.

[0003] In industrial production, the purification and recycling of cooling water through filtration devices is a crucial step in ensuring stable equipment operation. However, as filtration continues, the filter media traps impurities in the water, gradually accumulating and causing blockages. When the blockage reaches a certain level, maintenance of the filtration device is necessary. This process not only requires significant manpower but is also time-consuming, inevitably interrupting the continuous operation of the production line, thus affecting production efficiency and causing additional production losses. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, the cooling water circulating filter device for air separation equipment of this utility model, through the setting of the flushing mechanism, can clean the filter media inside the filter device body, effectively preventing the filter media from clogging and reducing the maintenance frequency.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a cooling water circulating filtration device for air separation equipment, comprising: a filtration device body and a flushing mechanism, wherein the flushing mechanism includes a support base, a water pump, a first water supply pipe, a second water supply pipe, an outlet pipe, a first valve, a drain pipe, and a second valve, wherein the outlet pipe is connected to one end of the filtration device body, the first valve is connected to the other end of the outlet pipe, the second water supply pipe is connected to the other end of the outlet pipe, and the output end of the water pump is connected to the other end of the outlet pipe; the first water supply pipe is connected to the input end of the water pump; one end of the drain pipe is connected to the filtration device body, and the second valve is connected to the other end of the drain pipe.

[0007] In addition, the cooling water circulating filter device for air separation equipment proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the filtration mechanism includes a filter tube, multiple first filter screens, activated carbon, and quartz wool. The filter tube is installed on the outer wall of the main body of the filtration device. Multiple fixing grooves are opened on the inner surface of the filter tube. The multiple first filter screens are installed in their respective fixing grooves. The activated carbon and quartz wool are installed sequentially between the multiple first filter screens.

[0009] Specifically, the main body of the filtration device includes a base, multiple support feet, a tank, and a water inlet pipe. The multiple support feet are respectively mounted on the base; the tank is mounted on the support feet; and the water inlet pipe is mounted on the outer wall of the tank.

[0010] Specifically, a second filter screen is installed on the inner wall of the sewage pipe.

[0011] Specifically, one end of the filter tube has an installation groove, and a sealing ring is installed inside the installation groove.

[0012] Specifically, a support base is provided on the main body of the filter device.

[0013] Compared with existing technologies, the cooling water circulation filtration device for air separation equipment of this invention, through the setting of a flushing mechanism, can periodically clean the filter media inside the main body of the filtration device, effectively preventing clogging of the filter media, extending the service life of the filter media, and reducing maintenance frequency.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] The following describes a cooling water circulating filter device for an air separation unit according to an embodiment of the present invention, with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, the cooling water circulating filter device for air separation equipment according to this utility model embodiment includes: filter device body 1 and rinsing mechanism 2.

[0024] The flushing mechanism 2 includes a support base 21, a water pump 22, a first water supply pipe 23, a second water supply pipe 24, a water outlet pipe 25, a first valve 26, a sewage discharge pipe 27, and a second valve 28.

[0025] Among them, the water outlet pipe 25 is connected to one end of the filter device body 1, the first valve 26 is connected to the other end of the water outlet pipe 25, the second water supply pipe 24 is connected to the other end of the water outlet pipe 25, the output end of the water pump 22 is connected to the other end of the water outlet pipe 25, the first water supply pipe 23 is connected to the input end of the water pump 22, one end of the sewage pipe 27 is connected to the filter device body 1, and the second valve 28 is connected to the other end of the sewage pipe 27.

[0026] Specifically, when it is necessary to clean the filter media inside the filter device body 1, firstly close the first valve 26 and the second valve 28, then start the water pump 22. The water pump 22 draws clean water from the outside through the first water supply pipe 23, pressurizes the clean water, and delivers it to the outlet pipe 25 through the second water supply pipe 24. The clean water enters the filter device body 1 through the outlet pipe 25 to backwash the internal filter media. During the rinsing process, impurities and dirt attached to the filter media are washed off by the water flow. Then, the second valve 28 is opened to discharge the impurities and dirt through the drain pipe 27, completing the entire rinsing process. This is used to clean the filter media regularly, prevent clogging, extend the service life of the filter media, and reduce the maintenance frequency. After rinsing is completed, the first valve 26 is opened and the second valve 28 is closed, allowing the filter device body 1 to resume normal filtration operation.

[0027] In one embodiment of this application, such as Figure 3 As shown, a filter mechanism 3 is provided on the outer wall of the main body 1 of the filter device.

[0028] The filtration mechanism 3 includes a filter tube 31, multiple first filter screens 33, activated carbon 34, and quartz wool 35.

[0029] The filter tube 31 is installed on the outer wall of the filter device body 1. Multiple fixing grooves 32 are opened on the inner surface of the filter tube 31. Multiple first filter screens 33 are installed in the corresponding fixing grooves 32. Activated carbon 34 and quartz wool 35 are installed between the multiple first filter screens 33 in sequence.

[0030] Specifically, the filter mechanism 3 achieves preliminary filtration. First, when water flows through the filter pipe 31, it encounters the first filter screen 33, which blocks larger particles and impurities, thus performing preliminary filtration. Next, the water flows through the activated carbon layer 34. Due to its strong adsorption capacity, the activated carbon 34 effectively adsorbs organic matter, residual chlorine, odors, and other impurities in the water, further improving water quality. Finally, the water flows through the quartz wool layer 35. The quartz wool 35, with its fine fiber structure, further blocks tiny particles, ensuring water purity. Through this multi-layered filtration design, the filter mechanism 3 efficiently purifies the water, providing higher-quality inlet water for subsequent filtration, thereby improving the overall efficiency and filtration effect of the cooling water circulation filtration device. Furthermore, both ends of the filter pipe 31 are threaded, facilitating connection to other pipes. This not only makes installation and disassembly convenient but also facilitates cleaning and maintenance of the filter mechanism 3, ensuring its continuous and efficient operation.

[0031] In one embodiment of this application, such as Figure 1 As shown, the main body 1 of the filter device includes a base 11, multiple support feet 12, a tank 13, and a water inlet pipe 14.

[0032] Multiple support feet 12 are respectively set on the base 11, the tank body 13 is set on the support feet 12, and the water inlet pipe 14 is set on the outer wall of the tank body 13.

[0033] Specifically, one end of the inlet pipe 14 is connected to the water source, and the other end extends into the tank 13 so that the water to be filtered is introduced into the tank 13. The tank 13 is the main part of the filtration device. The design of the tank 13 has a certain pressure bearing capacity to ensure that it can withstand a certain water pressure during the filtration process and ensure the stable operation of the filtration work. The base 11 and the support feet 12 play the role of supporting and stabilizing the tank 13, ensuring that the entire filtration device will not shake or tilt during operation, further improving the stability and safety of the filtration work.

[0034] In one embodiment of this application, such as Figure 4 As shown, a second filter screen 4 is installed on the inner wall of the drain pipe 27.

[0035] Understandably, the second filter screen 4 is designed to prevent larger filter media from being discharged with the wastewater.

[0036] In one embodiment of this application, such as Figure 3 As shown, a mounting groove 5 is provided at one end of the filter tube 31, and a sealing ring 6 is installed inside the mounting groove 5.

[0037] Understandably, the installation groove 5 allows the sealing ring 6 to be better fixed at one end of the filter tube 31, preventing water from seeping out from the gap between the filter tube 31 and the installation position, thus improving the sealing performance of the entire device.

[0038] In one embodiment of this application, such as Figure 2 As shown, a support base 21 is provided on the main body 1 of the filter device.

[0039] Understandably, the support base 21 is configured to provide stable support for the water pump 22.

[0040] In summary, the cooling water circulation filtration device for air separation equipment of this utility model, through the flushing mechanism 2, can periodically clean the filter media inside the main body 1 of the filtration device, effectively preventing clogging of the filter media, extending the service life of the filter media, and reducing the maintenance frequency. Simultaneously, through the filtration mechanism 3, a multi-level filtration design is achieved, which can efficiently purify water quality and provide higher-quality inlet water for subsequent filtration work, thereby improving the overall working efficiency and filtration effect of the cooling water circulation filtration device.
