[0002] During the pipe network transportation process, tap water will inevitably be polluted by rust, sediment, organic matter and microorganisms, and the water purification system with purification function can play a good role in removing impurities and purifying tap water. The water purification system of the water purification system usually includes a pre-filter element, a precision filter element, and a post-treatment filter element. The pre-filter element is used to remove organic matter, colloids, heavy metals and sediment particles, etc. The precision filter element is extremely accurate, such as the reverse osmosis membrane filter element (RO filter element), which is the core treatment filter element of the water purification system. The post-treatment filter element is used to remove trace elements, adjust pH and drinking taste, etc.

[0003] The activated carbon component in the pre-filter can effectively remove oxidizing substances such as residual chlorine, so the activated carbon component is an indispensable and important component of the pre-filter. However, the activated carbon component of the pre-filter has a shorter lifespan than other filter elements, resulting in frequent replacement of the pre-filter, high cost and limiting the nominal value of the rated water purification volume of the entire machine.

[0006] Beneficial effect: The water purification system of the present application, when the water purification system is in a regeneration state, injects regenerated water into the pre-filter element, and the regenerated water can break the balance between the activated carbon of the pre-filter element and the pollutant adsorbent, so that the pollutants are analyzed and desorbed, thereby restoring part of the adsorption capacity of the activated carbon component and realizing the active regeneration of the pre-filter element. The regenerated water after thermal regeneration is discharged from the pre-filter element from the water outlet of the pre-filter element, and then the microwave generator is used to send microwaves to regenerate the pre-filter element.

[0076] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0077] Combine the following Figures 1 to 5 , describing an embodiment of the present invention.

[0078] like Figure 1 or Figure 2As shown, according to an embodiment of the present invention, on the one hand, a water purification system is disclosed, including a pre-filter element 1 and a microwave generator 2, wherein the pre-filter element 1 contains an activated carbon component, the pre-filter element 1 has a pre-filter element water outlet 12, the microwave generator 2 is connected to the pre-filter element 1, based on the water purification system being in a regeneration state, regenerated water is injected into the pre-filter element 1, the regenerated water thermally regenerates the pre-filter element 1, and the regenerated water after thermal regeneration is discharged from the pre-filter element 1 from the pre-filter element water outlet 12, and the microwave generator 2 sends microwaves to perform microwave regeneration on the pre-filter element 1.

[0079] The water purification system of the present application, when the water purification system is in a regeneration state, injects regenerated water into the pre-filter element 1, and the regenerated water can break the balance between the activated carbon of the pre-filter element 1 and the pollutant adsorbent, so that the pollutants are analyzed and desorbed, thereby restoring part of the adsorption capacity of the activated carbon component and realizing the active regeneration of the pre-filter element 1, and the regenerated water after thermal regeneration is discharged from the pre-filter element 1 from the pre-filter element water outlet 12, and then the microwave generator 2 is used to send microwaves to regenerate the pre-filter element 1, and the microwaves can further regenerate the activated carbon inside the pre-filter element 1. The microwave regeneration technology has the advantages of not introducing secondary pollution, fast heating speed, high regeneration efficiency and low exhaust gas generation. The present application combines thermal regeneration and microwave regeneration to achieve the purpose of increasing the service life of the pre-filter element 1 and extending the element replacement cycle, thereby removing restrictions on the increase of the nominal value of the rated water purification volume of the whole machine and improving the product competitiveness.

[0080] The microwave regeneration principle is that the microwave energy generated by the microwave generator 2 induces the substance molecules adsorbed by the activated carbon of the pre-filter 1 to produce dipole steering polarization in the microwave field, and quickly converts the microwave energy into heat energy, thereby restoring the adsorption performance of the activated carbon and improving the service life of the pre-filter 1.

[0081] Optionally, the pre-filter 1 can be set as a carbon composite filter composed of a first-level PP cotton, ultrafiltration and activated carbon in series, which can filter colloids, heavy metals and sediment particles, etc., and can remove oxidizing substances such as residual chlorine.

[0082] like Figure 3 As shown, in some embodiments, the regenerated water is hot water of a preset temperature, and the pre-filter element 1 has a water injection port 13 , through which the regenerated water is injected into the pre-filter element 1 .

[0083] By providing a water injection port 13 on the pre-filter element 1 , when the water purification system is in a regeneration state, hot water of a preset temperature is injected into the pre-filter element 1 through the water injection port 13 , thereby achieving thermal regeneration of the pre-filter element 1 .

[0084] It should be noted here that the water inlet 13 is provided with a sealing cover, and the water inlet 13 is opened only when the water purification system is in a regeneration state, and is closed when the water purification system is in a water purification state, so as to ensure the normal filtering function of the pre-filter 1.

[0085] like Figure 1 or Figure 2 As shown, in some embodiments, the pre-filter element 1 has a pre-filter element water inlet 11 , and the regenerated water is injected into the pre-filter element 1 through the pre-filter element water inlet 11 .

[0086] In this scheme, recycled water is injected into the pre-filter element 1 through the pre-filter element water inlet 11 to achieve thermal regeneration of the pre-filter element 1. There is no need to open an additional water injection hole on the pre-filter element 1, which reduces the processing steps and can also ensure the sealing of the pre-filter element 1.

[0087] In some embodiments, the water purification system further includes a heating device 3, and the heating device 3 is used to heat the regenerated water to a preset temperature.

[0088] The heating device 3 provided can heat the regenerated water to a preset temperature to ensure that the temperature of the regenerated water is within an appropriate range, thereby ensuring the thermal regeneration effect of the pre-filter element 1 .

[0089] like Figure 2 As shown, in some embodiments, the heating device 3 is disposed inside the pre-filter element 1, and the heating device 3 can heat the regenerated water flowing into the pre-filter element 1 to a preset temperature.

[0090] After the regenerated water flows into the pre-filter element 1 , it can be heated to a preset temperature by the heating device 3 . The regenerated water at the preset temperature can perform thermal regeneration on the pre-filter element 1 .

[0091] like Figure 1 As shown, in some embodiments, the water purification system also includes a water inlet pipeline 200, which is connected to the water inlet 11 of the pre-filter element, and the regenerated water flows into the pre-filter element 1 through the water inlet pipeline 200, and the heating device 3 is arranged in the water inlet pipeline 200.

[0092] Under this scheme, when the regenerated water flows through the clean water pipeline, it is heated to a preset temperature by the heating device 3, and the regenerated water at the preset temperature then flows into the pre-filter element 1 for thermal regeneration. The regenerated water under this scheme flows into the pre-filter element 1 and can be directly thermally regenerated without a heating process, thereby improving the thermal regeneration efficiency.

[0093] It should be noted that the regenerated water may specifically be tap water, well water, etc. For ease of explanation, this embodiment uses the regenerated water as tap water for illustrative purposes.

[0094] Optionally, the heating device 3 can be a stainless steel heating tube, an electric heating wire, etc., which can be selected and set according to specific needs. This embodiment does not make specific restrictions. The heat generated by the stainless steel heating tube, the electric heating wire, etc. can quickly heat the recycled water to a preset temperature.

[0095] In some embodiments, the preset temperature is 80°C to 100°C.

[0096] The regenerated water at 80°C to 100°C has a good analytical desorption effect on the adsorbate of the activated carbon component of the pre-filter element 1, and can enhance the desorption effect of the adsorbate.

[0097] Exemplarily, the preset temperature may be 80° C., 85° C., 90° C., 95° C., 100° C., etc., and may be set as required, and this embodiment does not impose any specific limitation.

[0098] In some embodiments, the water inlet pipeline 200 is provided with a water inlet valve 201 , and the water inlet valve 201 is located upstream of the heating device 3 .

[0099] When the water purification system is in a regeneration state, the water inlet valve 201 is started, and the regenerated water flows from the water inlet pipe 200 through the water inlet valve 201 and the heating device 3 and then flows into the pre-filter element 1 to perform thermal regeneration on the pre-filter element 1. The water inlet valve 201 is arranged upstream of the heating device 3 to avoid high temperature damage to the water inlet valve 201, thereby ensuring the service life of the water inlet valve 201.

[0100] In some embodiments, the microwave generating device 2 is disposed at the bottom of the pre-filter element 1 .

[0101] By arranging the microwave generating device 2 at the bottom of the pre-filter element 1, the interference between the microwave generating device 2 and components such as pipelines and valves on the pre-filter element 1 can be reduced, thereby ensuring the independent use of each.

[0102] Specifically, an end cover is provided at the bottom of the pre-filter element 1 , the microwave generating device 2 is embedded in the end cover, and the microwave emitting end of the microwave generating device 2 extends into the interior of the pre-filter element 1 through the end cover to transmit microwaves to the interior of the pre-filter element 1 .

[0103] The microwave generator 2 is used to emit microwaves to the interior of the pre-filter element 1. The microwave energy is converted into heat energy to further heat and regenerate the pre-filter element 1. The high temperature generated by the microwave generator 2 can be higher than the temperature of the regenerated water. Therefore, the pre-filter element 1 can be further regenerated through the microwave generator 2.

[0104] Since the technology and principle of the microwave generating device 2 are prior art, they will not be described in detail in this embodiment.

[0105] like Figure 1 or Figure 2 As shown, in some embodiments, the water purification system also includes a fine filter element 4 and a wastewater discharge pipeline 400, wherein the fine filter element 4 has a fine filter element water inlet 41, a wastewater outlet 43 and a pure water outlet 42, the fine filter element water inlet 41 and the pre-filter element water outlet 12 are connected by a first pipeline 300, the first pipeline 300 is provided with a pressure-stabilizing pump 301, the wastewater discharge pipeline 400 is connected to the wastewater outlet 43, and the wastewater discharge pipeline 400 is provided with a wastewater valve 401.

[0106] When the water purification system is in a regeneration state, the regenerated water in the pre-filter element 1 is discharged to the first pipeline 300 through the pre-filter element outlet 12, and then discharged into the fine filter element 4 through the first pipeline 300 and then discharged through the wastewater discharge pipeline 400 and the pure water outlet 42.

[0107] Of course, when the water purification system is purifying water normally, the fine filter element 4 is used to perform high-precision filtration on tap water. The tap water flows into the fine filter element 4 through the fine filter element water inlet 41. The pure water produced after filtration is discharged through the pure water outlet 42, and the waste water produced is discharged to the waste water discharge pipeline 400 through the waste water outlet 43.

[0108] The fine filter element 4 has higher filtering accuracy than the pre-filter element 1 and can further purify the tap water with high precision. It is the core processing filter element of the water purification system.

[0109] The fine filter element 4 can specifically be a reverse osmosis membrane filter element (RO filter element), a ceramic filter element, etc., which is selected according to the filtering requirements and is not specifically limited in this embodiment.

[0110] like Figure 1 or Figure 2 As shown, in some embodiments, the water purification system also includes a post-filter element 5, which has a post-filter element water inlet 51 and a post-filter element water outlet 52, the post-filter element water inlet 51 and the pure water port 42 are connected by a second pipeline 500, and the post-filter element water outlet 52 is connected to the pure water pipeline 600.

[0111] When the water purification system is purifying water normally, the post-filter element 5 can filter the pure water flowing out of the fine filter element 4 again to improve the taste of pure water. When the water purification system is in a regeneration state, the regenerated water in the pre-filter element 1 is discharged into the fine filter element 4 through the first pipeline 300 and then discharged through the pure water port 42, the second pipeline 500, the post-filter element 5, the pure water pipeline 600, and the waste water discharge pipeline 400.

[0112] Specifically, the post-filter element 5 may be a post-activated carbon filter element containing activated carbon components.

[0113] The second pipeline 500 is provided with a check valve 501 , which can prevent the pure water in the post-filter element 5 from flowing back into the fine filter element 4 .

[0114] In order to improve the compactness of the structure and reduce the volume of the whole machine, in some embodiments, the pre-filter element 1 and the post-filter element 5 can be integrated to form a composite filter element. For example, the pre-filter element 1 and the post-filter element 5 can be independently separated and arranged in the inner cavity of the same filter bottle, and the pre-filter element water inlet 11, the pre-filter element water outlet 12, the post-filter element water inlet 51 and the post-filter element water outlet 52 are all arranged at the top of the filter bottle, and the microwave generating device 2 can be arranged at the bottom of the filter bottle.

[0115] Preferably, the filter bottle of the composite filter element and the filter bottle of the pre-filter element 1 are made of stainless steel, which is resistant to high temperatures and can withstand the high temperature generated when the microwave generator 2 is working. Specifically, the stainless steel material can be 304 stainless steel or 316 stainless steel, etc., and this embodiment does not make specific restrictions.

[0116] In some embodiments, the water purification system also includes a pre-treatment filter element 6, which has a pre-treatment filter element water inlet and a pre-treatment filter element water outlet, the pre-treatment filter element water inlet is connected to the raw water pipeline 100, and the pre-treatment filter element water outlet and the pre-filter element water inlet 11 of the pre-filter element 1 are connected through the water inlet pipeline 200.

[0117] When the water purification system is purifying water normally, the pre-treatment filter element 6 can pre-filter the raw water flowing into the raw water pipeline 100 to filter out large particles of impurities such as mud, rust, etc. in the raw water to ensure the service life of the rear filter element. When the water purification system is in a regeneration state, the regenerated water flows through the raw water pipeline 100 in sequence through the pre-treatment filter element 6, the water inlet pipeline 200, the water inlet valve 201, and flows into the pre-filter element 1 to perform thermal regeneration on the pre-filter element 1.

[0118] In this embodiment, the raw water pipeline 100 is connected to the tap water inlet so as to facilitate the long-distance transportation of the tap water to the water purification system.

[0119] The raw water pipeline 100 is provided with a raw water inlet switch 101, which is used to control the on-off of the raw water pipeline 100. When the raw water inlet switch 101 is turned on, the raw water pipeline 100 is turned on, and tap water can flow into the pre-treatment filter element 6 through the raw water pipeline 100. When the raw water inlet switch 101 is turned off, the raw water pipeline 100 is disconnected, and tap water cannot flow through the raw water pipeline 100 into the pre-treatment filter element 6.

[0120] In order to facilitate the understanding of the water purification system of this application, Figure 1 , the working process of the water purification system is introduced as follows:

[0121] It should be noted that the heating device 3 is disposed on the water inlet pipe 200 for the purpose of explanation.

[0122] The water purification system is in the water purification working state: the raw water inlet opening, the water inlet valve 201, the pressure regulating pump 301 and the waste water valve 401 are opened, the heating device 3 and the microwave generating device 2 are both in the closed state, the raw water (tap water) flows into the pre-treatment filter element 6 through the raw water inlet opening and the raw water pipeline 100, the pre-treatment filter element 6 pre-filters the raw water to filter out large particles of impurities such as sand and rust in the raw water, the filtered raw water flows through the water inlet pipeline 200 and flows into the pre-filter element 1, the pre-filter element 1 filters the colloids and heavy metals in the raw water The raw water after filtration flows into the fine filter element 4 through the first pipeline 300 and the fine filter element water inlet 41. The fine filter element 4 performs high-precision filtration on the raw water. The waste water generated by filtration is discharged to the waste water discharge pipeline 400 through the waste water outlet 43. The pure water generated after filtration flows into the post-filter element 5 through the pure water outlet 42 and the second pipeline 500. The sense and pH value of the pure water outlet 42 are adjusted by the post-filter element 5. Then the pure water flows out through the pure water pipeline 600 for users to use.

[0123] The water purification system is in the regeneration state. The operation steps for regeneration are as follows:

[0124] (1) Open the raw water inlet, the water inlet valve 201, the pressure regulating pump 301, the wastewater valve 401 and the heating device 3, and the microwave generator 2 is in the closed state. The regenerated water (tap water) flows through the raw water inlet switch 101, the pre-treatment filter element 6, the water inlet pipeline 200, the water inlet valve 201, the heating device 3, the pre-filter element water inlet 11 and flows into the pre-filter element 1. When the regenerated water fills the pre-filter element 1, the regenerated water overflows through the pre-filter element water outlet 12 and is discharged through the first pipeline 300, the fine filter element 4, the wastewater discharge pipeline 400 and the second pipeline 500, the post-filter element 5, and the pure water pipeline 600. The regenerated water injection time lasts for 1 minute to 10 minutes;

[0125] (2) closing the raw water inlet opening, the water inlet valve 201, the pressure regulating pump 301, the waste water valve 401 and the heating device 3, and soaking the pre-filter element 1 with the filled recycled water for 1 hour to 10 hours, so as to better desorb the adsorbent of the activated carbon in the pre-filter element 1;

[0126] (3) Open the pressure-stabilizing pump 301 and the wastewater valve 401 to drain the regenerated water inside the pre-filter element 1;

[0127] (4) The pressure regulating pump 301 and the wastewater valve 401 are closed, and then the microwave generator 2 is turned on. The microwave generator 2 emits microwaves to regenerate the pre-filter element 1. The working time of the microwave generator 2 is 60 minutes to 120 minutes;

[0128] (5) Repeat the above steps 1 to 10 times.

[0129] Of course, it is understandable that in the above step (1), the regenerated water can also be injected into the pre-filter element 1 through the water injection port 13 of the pre-filter element 1; the regenerated water can also be heated by the heating device 3 inside the pre-filter element 1.

[0130] It should be noted that the regeneration triggering condition of the water purification system can be controlled by setting the total amount of purified water. For example, when the total amount of purified water in the water purification system reaches 1000L or 1500L, the water purification system is triggered to enter the regeneration state, and the pre-filter element 1 is actively regenerated, but it is not limited to this. In other embodiments, the regeneration triggering condition of the water purification system can also be controlled by setting the water purification time.

[0147] In some embodiments, in the step of controlling the microwave generating device 2 to send microwaves to perform microwave regeneration on the pre-filter element 1 , the working time of the microwave generating device 2 is 60 minutes to 120 minutes.

[0148] By reasonably setting the working time of the microwave generating device 2 , the microwave regeneration effect of the microwave generating device 2 on the pre-filter element 1 can be improved.

[0149] Specifically, the working time of the microwave generating device 2 can be 60 minutes, 70 minutes, 80 minutes, 90 minutes, 100 minutes, 110 minutes, 120 minutes, etc., which can be set according to specific needs and is not specifically limited in this embodiment.

[0150] In some embodiments, in the step of repeating the above steps n times, the value of n is 1-10.

[0151] By setting the value range of n reasonably and making the thermal regeneration and microwave regeneration alternately cycle for a reasonable number of times, the active regeneration effect of the pre-filter element 1 can be ensured.

[0152] Specifically, the value of n can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc., which can be set according to specific needs and is not specifically limited in this embodiment.
