Description

Technical Field

[0001] This utility model belongs to the field of evaporative cold descaling technology, and more specifically, it relates to a split-type evaporative cold descaling device. Background Technology

[0002] Central air conditioning water systems and evaporative cooling systems require spraying cooling water onto the pipes for cooling during operation. The sprayed water then falls into the evaporative cooling water tank for recycling. Because the cooling water contains calcium and magnesium ions, acidic carbonates, sand, silt, algae, and other particulate matter, hydrocarbons are formed on the surface of the high-temperature metal pipes after spraying, resulting in hard scale. Evaporative cooling systems, being open structures, are particularly susceptible to scale formation due to airborne dust and bacteria. Severe scale buildup significantly affects the heat exchange efficiency of the equipment, reducing its heat transfer capacity and increasing power consumption. Furthermore, scale corrodes the pipes, shortening the equipment's lifespan. Therefore, regular descaling is necessary.

[0003] Currently, descaling is mainly achieved by adding a strong magnetic scale inhibitor or descaling device to the spray water inlet of the central air conditioning water system and evaporative cooling equipment. However, in actual operation, the following problems exist: 1. The descaling effect is not ideal, and there is a lot of soft scale in the water that falls into the evaporative cooling water tank after spraying, which makes it impossible to recycle the water in the tank, resulting in serious waste of water resources and affecting the heat exchange efficiency of the equipment, increasing electricity consumption; 2. Each central air conditioning water system or evaporative cooling equipment needs to be equipped with a descaling device, which cannot achieve the working mode of one device acting on multiple evaporative cooling or central air conditioning units at the same time.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figures 1 to 7As shown, the split-type evaporative cooling descaling equipment includes a first descaling mechanism and a second descaling mechanism, which are set separately. The first descaling mechanism is usually installed at a high position, located on one side of the central air conditioning water system or evaporative cooling system. It is used to directly spray the purified and descaled water onto the pipes of the central air conditioning water system or evaporative cooling system to reduce the scale generated on the pipes. The second descaling mechanism is usually installed on the ground, forming a staggered layer with the first descaling mechanism. The second descaling mechanism is used to filter and purify the water that falls into the evaporative cooling water tank 18 after spraying, thereby removing soft scale and other impurities in the water. This allows the water in the evaporative cooling water tank 18 to be recycled, realizing multiple spraying uses, saving purified water resources, and greatly reducing the formation of scale on the pipes.

[0030] Specifically, the first descaling mechanism includes a first support 9, on which a first hydrocyclone 1, a second hydrocyclone 2, and an upper filter water tank 10 are fixedly installed. The first hydrocyclone 1 and the second hydrocyclone 2 adopt existing hydrocyclone separators. The first hydrocyclone 1 serves as the starting point of the entire first descaling mechanism. The inlet of the first hydrocyclone 1 is connected to the water supply system or the underground water tank 19 through the water pump 17, which allows cooling water to enter the mechanism smoothly. The cooling water enters the first hydrocyclone 1 tangentially. Utilizing the principle of vortex, during the high-speed rotation of the cooling water, larger particles of impurities and sand are thrown towards the wall of the device due to centrifugal force, thus initially separating from the cooling water.

[0031] The outlet of the first hydrocyclone 1 is equipped with a strong magnetic scale inhibitor 103. This strong magnetic scale inhibitor is existing technology; it uses a magnetic field to alter the form of calcium and magnesium ions in the cooling water, making them less prone to forming hard scale and effectively preventing scaling problems in subsequent pipes and equipment. The drain outlet of the first hydrocyclone 1 is equipped with a first sand storage filter 101, which is connected to the inlet of the second hydrocyclone 2 via a first control valve 102. The pre-treated cooling water continues to enter the second hydrocyclone 2 for further separation and purification. The second hydrocyclone 2 again utilizes cyclone technology to separate the remaining smaller particulate impurities in the cooling water. The drain outlet of the second hydrocyclone 2 is equipped with a second sand storage filter 201, which is connected to the upper filter tank 10. The separated impurities can enter the upper filter tank 10 for solid-liquid separation, and the solid impurities are removed.

[0032] All the sand filters mentioned in this case, including the first sand filter 101, the second sand filter 201, and the subsequent third sand filter 401 and fourth sand filter 308, have the same structure. They all include a sand storage tank, which is used to settle sand and scale impurities. Electromagnets are installed at both ends of the sand storage tank. When the electromagnets are energized, they can use magnetic force to attract rust stains. When the electromagnets are de-energized and are used in conjunction with a control valve, the aforementioned impurities can be discharged periodically. A heating element is wrapped around the middle of the sand storage tank to prevent the sand storage tank from freezing in cold environments.

[0033] The first descaling mechanism is also equipped with a descaling liquid tank 8, which is filled with descaling liquid. The bottom of the descaling liquid tank 8 is equipped with a descaling liquid outlet pipe, and a descaling liquid control valve 801 and a descaling liquid pump 802 are installed on the descaling liquid outlet pipe. When in use, the descaling liquid outlet pipe is connected to the central air conditioning water system and the spray pipe of the evaporative cooling system. When the hard scale on the pipe is not removed, spraying the descaling liquid helps to dissolve the hard scale into soft scale, thereby improving the descaling efficiency.

[0034] The upper end of the second hydrocyclone 2 is connected to a second hydrocyclone outlet pipe, which is connected to the descaling solution outlet pipe. An activator 203 and a one-way valve 204 are installed on the second hydrocyclone outlet pipe. The activator 203 activates the liquid, enhancing the descaling effect, while the one-way valve 204 prevents backflow and ensures normal system operation. During operation, the second hydrocyclone outlet pipe is connected to the spray pipe, allowing the filtered water to continue to be used for spray cooling.

[0035] The second descaling mechanism includes a second support 13, on which a third hydrocyclone 4, a hydrocyclone purification drain 3, and a lower filter water tank 14 are fixedly installed. Both the third hydrocyclone 4 and the hydrocyclone purification drain 3 are hydrocyclone separators. The inlet of the third hydrocyclone 4 is connected to the upper filter water tank 10 or the evaporative cooling water tank 18. In this embodiment, the upper filter water tank 10 is connected to the evaporative cooling water tank 18. The water in the evaporative cooling water tank 18 enters the third hydrocyclone 4 for further separation. Under the action of cyclone, impurities and particles in the cooling water are further separated. The outlet of the third hydrocyclone 4 is connected to the inlet pipe 302 of the hydrocyclone purification drain 3. The liquid treated by the third hydrocyclone 4 enters the hydrocyclone purification drain 3 for further purification. The drain outlets of both the third hydrocyclone 4 and the hydrocyclone purification drain 3 are connected to the lower filter water tank 14 through a sand storage filter. The sand storage filter can effectively collect and filter out the separated rust and impurities, ensuring that the discharged liquid reaches a certain purity. The outlet 304 of the cyclone purifier / sewage drainer 3 is sequentially connected to an algae remover / sterilizer 11 and a scale inhibitor 12. Both the algae remover / sterilizer 11 and the scale inhibitor 12 are existing technologies. The scale inhibitor 12 includes a second strong magnetic scale inhibitor 1201, an activator 1202, and a carbon filter 1203 connected in sequence. The algae remover / sterilizer 11 can effectively kill algae and bacteria and other microorganisms in the liquid, ensuring the hygiene and safety of the liquid. The scale inhibitor 12 further refines the cooling water by filtering it, removing residual microparticles and scale components, so that the treated liquid achieves a higher purity.

[0036] The second descaling mechanism is equipped with a scale inhibitor tank 5. The bottom of the scale inhibitor tank 5 is connected to the underground water tank 19 through a regulating valve. The flow rate of the scale inhibitor can be controlled by the regulating valve. When an appropriate amount of scale inhibitor is injected into the underground water tank 19, it can prevent scale formation when the cooling water is circulated and sprayed.

[0037] In this embodiment, liquid outlet filter screens 21 are fixedly connected to the first hydrocyclone 1, the second hydrocyclone 2, the third hydrocyclone 4, and the hydrocyclone purification and sewage discharge device 3 near the liquid outlet. The cross-section of the liquid outlet filter screen 21 is arc-shaped, with the middle part of the arc bending away from the liquid outlet. This arc-shaped structure design can increase the filtration area of ​​the filter screen, improve the filtration efficiency, and also facilitate the flow of liquid and the interception of impurities.

[0038] The cyclone purification drainer 3 is a key purification component in the second descaling mechanism. Specifically, the cyclone purification drainer 3 includes a cyclone tank body 301. At least two layers of metal filter screens 306 are fixedly connected to the upper part of the cyclone tank body 301. A carbon filter layer 305 is filled between adjacent metal filter screens 306. The metal filter screens 306 can intercept larger particles of impurities, while the carbon filter layer 305 can remove odors, pigments, and some harmful substances from the liquid through adsorption. Below the metal filter screens 306 is an arc-shaped filter screen 307. A rotating cleaning mechanism 20 is provided between the arc-shaped filter screen 307 and the bottom metal filter screen 306. A cleaning pipe 303 is connected to the rotating cleaning mechanism 20 and is fixedly connected to the cyclone tank body 301. The rotating cleaning mechanism 20 can clean the arc-shaped filter screen 307, allowing impurities adhering to the bottom of the arc-shaped filter screen 307 to be washed away.

[0039] The rotary cleaning mechanism 20 includes a rotary head 2001, which is rotatably connected to the end of a cleaning pipe 303. Multiple evenly distributed flushing pipes 2002 are connected to the circumference of the rotary head 2001. The end of the flushing pipe 2002 away from the rotary head 2001 is bent downwards at an angle. When the arc-shaped filter screen 307 inside the cyclone tank body 301 needs to be cleaned, water is injected into the rotary head 2001 through the cleaning pipe 303. The water flows out from the flushing pipe 2002 and impacts the arc-shaped filter screen 307. Under the reaction force of the water flow, the rotary head 2001 drives the flushing pipe 2002 to rotate at high speed, achieving all-round flushing and ensuring that impurities at the bottom of the arc-shaped filter screen 307 are thoroughly cleaned.

[0040] A water supply pipe 15 is connected to the cyclone tank body 301. An activator and a check valve are installed on the water supply pipe 15. The water supply pipe 15 is connected to the water supply system through a pump. When the liquid volume in the evaporative cooling system and the cyclone tank body 301 is insufficient, the liquid can be replenished in time through the water supply pipe 15.

[0041] The upper filter tank 10 and the lower filter tank 14 have the same structure, both including a tank body 1001. A front baffle 1003 is rotatably connected to the upper part of one side of the tank body 1001. A handle is fixed on the front baffle 1003. A pull-out filter basket 1002 is provided inside the tank body 1001. The front baffle 1003 can be opened by the handle, making it convenient for staff to pull out the filter basket 1002 to clean solid impurities. The bottom of the filter basket 1002 is provided with two or more layers of metal filter mesh 1004. The metal filter mesh 1004 is fixedly connected to the inner wall of the tank body 1001. A carbon filter layer 1005 is filled between adjacent metal filter meshes 1004. This structure can further filter and purify the cooling water entering the tank body 1001, thereby improving the purification quality of the cooling water. A drain pipe 1006 runs through the bottom of the water tank body 1001. The upper end of the drain pipe 1006 is located inside the water tank body 1001 and is located below the metal filter screen 1004. An umbrella-shaped filter screen 1007 is fixedly connected to the upper end of the drain pipe 1006. The umbrella-shaped filter screen 1007 can further effectively intercept impurities in the water and prevent them from entering the underground water tank 19 through the drain pipe 1006.

[0042] The first descaling mechanism is equipped with a solar photovoltaic panel 7 on its top, and the second descaling mechanism is equipped with a hydraulic generator 16. The hydraulic generator 16 is connected to the liquid outlet of the scale inhibitor 12. A battery 6 is installed on either the first or second descaling mechanism, or both the first and second descaling mechanisms may be equipped with batteries 6. Based on existing technology, the solar photovoltaic panel 7 and the hydraulic generator 16 are connected to the battery 6 via a rectifier and a charging controller. During equipment operation, the battery 6 is charged by solar energy, and during the evaporative cooling water circulation descaling process, the water circulation drives the hydraulic generator 16 to charge the battery 6, enabling the entire equipment to operate normally without an external power source.

[0043] Working principle: This utility model can be used for multiple evaporative coolers connected in series or in parallel to achieve a one-to-many working mode.

[0044] like Figure 2As shown, during installation, the outlets of the first hydrocyclone 1 and the second hydrocyclone 2 are connected to the central air conditioning water system or the spray pipe of the evaporative cooling system; the drain pipe of the upper filter water tank 10 is connected to the evaporative cooling water tank 18; the inlet of the third hydrocyclone 4 is connected to the evaporative cooling water tank 18; and the drain pipe of the lower filter water tank 14 is connected to the underground water tank 19. During operation, the inlet pump 17 is started, and the inlet pump 17 supplies cooling water to the first hydrocyclone 1. The cooling water is filtered by the first hydrocyclone 1 through swirling, and impurities are separated under the action of centrifugal force. The impurities fall downward into the first sand storage filter 101 for temporary storage under the action of gravity. After filtration, the filtered cooling water is filtered through the outlet filter screen 21 and enters the first strong magnetic scale inhibitor 103 to cut large water molecule clusters into small water molecule clusters and change their chemical bond angles. Then, it is passed into the spray pipe to spray and cool the pipeline. When the first control valve 102 is opened, impurities in the first sand storage filter 101 can periodically enter the second hydrocyclone 2 along with the filtered wastewater for further hydrocyclone separation. The filtered cooling water, after being filtered through the outlet filter screen 21, enters the activator 203 for activation treatment, and then flows into the spray pipe to spray and cool the pipeline. The impurities separated by the second hydrocyclone 2 fall into the second sand storage filter 201 under gravity for temporary storage. Opening the second control valve 202 can periodically send the impurities into the filter basket 1002 for filtration and separation. After being filtered by the metal filter screen 1004 and adsorbed and purified by the carbon filter layer 1005, the wastewater is filtered again through the umbrella-shaped filter screen 1007 and then sent to the evaporative cooling water tank 18. Water in the evaporative cooling water tank 18 enters the third hydrocyclone 4 for hydrocyclone filtration. Impurities separated under centrifugal force fall into the third sand storage filter 401 for temporary storage. By opening the third control valve 402, the water is periodically discharged into the lower filter water tank 14 for the separation of solid impurities. The separated water is filtered by the lower filter water tank 14 and then sent to the underground water tank 19 for recycling.

[0045] The water purified by the third hydrocyclone 4 enters the hydrocyclone tank body 301. First, it is filtered by hydrocyclone filtration to separate some impurities. These impurities are temporarily stored in the fourth sand storage filter 308 and periodically discharged into the lower filter water tank 14 through the fourth control valve 309. The filtered water is then filtered upward through the arc-shaped filter screen 307 for secondary filtration to remove fine impurities. Then, it is filtered sequentially through the metal filter screen 306, the carbon filter layer 305 for adsorption and purification, and the metal filter screen 306 again. After being filtered through the liquid outlet filter screen 21, it enters the algae removal and sterilization device 11 for sterilization and algae removal, and the scale inhibitor 12 for deep filtration and scale removal. Finally, it enters the lower filter water tank 14 through the hydraulic generator 16 and is then sent to the underground water tank 19 for recycling.

[0046] Through the above multiple cycles, impurities in the evaporative cooling water tank 18 and the underground water tank 19 can be separated and purified, making the cooling water purer and less prone to scaling during subsequent spray cooling.

[0047] When the arc-shaped filter screen 307 needs automatic cleaning, the pump is started, and water in the underground water tank 19 is pumped into the cleaning pipe 303. Water is then injected into the rotating head 2001 through the cleaning pipe 303. The water flows out from the flushing pipe 2002 and impacts the arc-shaped filter screen 307. Under the reaction of the water flow, the rotating head 2001 drives the flushing pipe 2002 to rotate at high speed, realizing all-round flushing of the arc-shaped filter screen 307 and ensuring that the impurities at the bottom of the arc-shaped filter screen 307 can be washed clean.

[0048] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
