技术领域technical field
本发明属于净化处理技术领域，具体公开了一种家用净水系统。The invention belongs to the technical field of purification treatment, and specifically discloses a household water purification system.
背景技术Background technique
现有的家用净水设备大多都是安装在厨房里面，以超滤膜净水设备和反渗透净水设备居多。上述净水设备能够过滤掉水中的杂质、部分微生物和部分有毒有害物质，净化处理后的水品质高。但是上述净水设备仍然还存在一些问题，一台净水设备无法对全家所有的用水进行净化，想要对厨房、卫生间、洗衣槽和阳台用水进行净化就必须购买多台净水设备，但是购买多台净水设备并不经济实用，所以大多数用户只会对厨房用水进行净化，而卫生间、洗衣槽和阳台用水则无法得到净化。同时，现有的净水设备多是针对水中的有毒有害物质进行净化，往往会忽略水中的镁离子和钙离子，实际上，我国部分地区的自来水的水质硬，水中的钙、镁离子多，直接使用自来水洗衣会导致衣服晾干后产生衣服硬的现象，长期使用自来水洗澡，水中的钙镁离子以及水中残留的氯会对皮肤造成一定损伤。同时部分用户家里使用的是电热水器，电热水器对水质硬的自来水加热会产生水垢，水垢不便清洗，而且降低电热水器的使用寿命。Most of the existing household water purification equipment is installed in the kitchen, most of which are ultrafiltration membrane water purification equipment and reverse osmosis water purification equipment. The above-mentioned water purification equipment can filter out impurities, some microorganisms and some toxic and harmful substances in the water, and the quality of the purified water is high. However, there are still some problems with the above-mentioned water purification equipment. One water purification equipment cannot purify all the water in the whole family. If you want to purify the water in the kitchen, bathroom, laundry tank and balcony, you must buy multiple water purification equipment. Multiple water purification equipment is not economical and practical, so most users only purify the kitchen water, but the toilet, laundry tank and balcony water cannot be purified. At the same time, most of the existing water purification equipment is aimed at purifying toxic and harmful substances in water, and magnesium ions and calcium ions in water are often ignored. In fact, the tap water in some areas of our country is hard, and there are many calcium and magnesium ions in water Directly using tap water for laundry will cause the clothes to become hard after drying. If you take a bath with tap water for a long time, the calcium and magnesium ions in the water and the residual chlorine in the water will cause certain damage to the skin. At the same time, some users use electric water heaters at home. Electric water heaters will produce scale when heated by hard tap water. The scale is inconvenient to clean and reduces the service life of the electric water heater.
发明内容Contents of the invention
本发明的目的在提供一种家用净水系统，以解决现有技术中净水设备无法对全家用水同时进行净化，以及无法去除钙镁离子和水中残留的氯而造成皮肤损伤的问题。The purpose of the present invention is to provide a household water purification system to solve the problem that the water purification equipment in the prior art cannot purify the whole household water at the same time, and cannot remove calcium and magnesium ions and residual chlorine in the water, causing skin damage.
为了达到上述目的，本发明的基础方案为：家用净水系统，包括控制柜和依次用管道连通连的预处理单元、软水单元、净水单元和储水器，所述预处理单元与家用自来水的总进水管连通，所述预处理单元和软水单元之间的管道上设有第一电磁阀，所述净水单元和储水器之间的管道上设有第二电磁阀，所述第一电磁阀和第二电磁阀分别与控制柜电连接，所述软水单元设有第一出水口和第二出水口，所述第一出水口与净水单元连通，所述第二出水口连通到卫生间和洗衣槽的进水管，还包括杀菌增压单元，所述杀菌增压单元并联设置在软水单元和储水器之间的连接管道上，所述杀菌增压单元包括输气管、出气管、进气管、高压储气装置、加热装置和紫外线灯，所述输气管的一端连通到软水单元，另一端连通到储水器，所述输气管的另一端设有第三电磁阀，所述第三电磁阀与控制柜电连接，所述出气管的一端连通到软水单元，另一端连通到高压储气装置，所述进气管的一端连通到高压储气装置，另一端连通到储水器，所述进气管的另一端设有第四电磁阀，所述第四电磁阀与控制柜电连接，所述加热装置设置在出气管上，所述紫外线灯设置在软水单元内，所述加热装置和紫外线灯分别与控制柜电连接，所述高压储气装置中充有氧气。In order to achieve the above object, the basic solution of the present invention is: a household water purification system, including a control cabinet and a pretreatment unit, a soft water unit, a water purification unit and a water storage device connected with a pipeline in sequence, and the said pretreatment unit is connected to the household tap water The main water inlet pipe is connected, the pipeline between the pretreatment unit and the soft water unit is provided with a first solenoid valve, the pipeline between the water purification unit and the water storage is provided with a second solenoid valve, and the first solenoid valve is provided on the pipeline between the water purification unit and the water storage A solenoid valve and a second solenoid valve are respectively electrically connected to the control cabinet, the soft water unit is provided with a first water outlet and a second water outlet, the first water outlet is connected to the water purification unit, and the second water outlet is connected to The water inlet pipe to the toilet and the laundry tank also includes a sterilizing supercharging unit, which is arranged in parallel on the connecting pipeline between the soft water unit and the water storage, and the sterilizing supercharging unit includes an air delivery pipe and an air outlet pipe , air intake pipe, high-pressure gas storage device, heating device and ultraviolet lamp, one end of the air pipe is connected to the soft water unit, the other end is connected to the water storage, the other end of the air pipe is provided with a third electromagnetic valve, the The third electromagnetic valve is electrically connected to the control cabinet, one end of the air outlet pipe is connected to the soft water unit, the other end is connected to the high-pressure gas storage device, one end of the air inlet pipe is connected to the high-pressure gas storage device, and the other end is connected to the water storage device , the other end of the air intake pipe is provided with a fourth electromagnetic valve, the fourth electromagnetic valve is electrically connected to the control cabinet, the heating device is arranged on the air outlet pipe, the ultraviolet lamp is arranged in the soft water unit, the heating The device and the ultraviolet lamp are respectively electrically connected to the control cabinet, and the high-pressure gas storage device is filled with oxygen.
本基础方案的工作原理在于：自来水先通过预处理单元进行初步净化，再进入到软水单元中。自来水进入到软水单元后，水中的镁离子和钙离子被去除，同时氧气从杀菌增压单元中进入到软水单元，经过紫外线灯的照射生成臭氧，臭氧对自来水进行杀菌处理，杀菌之后的自来水一部分进入到净水单元进行下一步的净化水处理，另一部分进入到卫生间和洗衣槽直接使用。臭氧在软水单元中对自来水消毒杀菌后，通过出气管流入到高压储气装置中，由于臭氧极其不稳定，在常温下20分钟内会转化为氧气，当臭氧在经过加热装置加热后更容易转化为氧气，所以当臭氧进入高压储气装置后绝大部分已经转化为氧气了。在用户需要使用厨房的水龙头时，高压储气装置中的氧气流动到储水器中，形成高压，达到用户所需的出水压力。当用户不需要使用厨房的水时，氧气再通过输气管流动到软水单元中，氧气经过紫外线灯的照射后形成臭氧，臭氧再对自来水进行杀菌处理。The working principle of this basic scheme is that the tap water is initially purified through the pretreatment unit, and then enters the soft water unit. After the tap water enters the soft water unit, the magnesium ions and calcium ions in the water are removed, and at the same time, oxygen enters the soft water unit from the sterilizing booster unit, and ozone is generated by the irradiation of ultraviolet lamps, and the ozone sterilizes the tap water, and a part of the tap water after sterilization Enter the water purification unit for the next step of purified water treatment, and the other part enters the toilet and laundry tank for direct use. After the ozone sterilizes the tap water in the soft water unit, it flows into the high-pressure gas storage device through the outlet pipe. Because the ozone is extremely unstable, it will be converted into oxygen within 20 minutes at room temperature. When the ozone is heated by the heating device, it is easier to convert It is oxygen, so when the ozone enters the high-pressure gas storage device, most of it has been converted into oxygen. When the user needs to use the faucet in the kitchen, the oxygen in the high-pressure gas storage device flows into the water storage to form a high pressure to reach the water outlet pressure required by the user. When the user does not need to use the water in the kitchen, the oxygen flows into the soft water unit through the air pipe, and the oxygen forms ozone after being irradiated by the ultraviolet lamp, and then the ozone sterilizes the tap water.
本基础方案的有益效果在于：与现有技术相比，从家庭用水的源头对自来水进行净化，解决了现有技术中无法对所有家庭用水进行净化的问题。同时，本方案还实现了自来水软化的目的，将自来水中的钙、镁离子去除，使用软化后的水清洗衣物不会产生衣物晾干后硬的现象，同时家中电热水器加热软化后的水不会产生水垢，延长了电热水器的使用寿命。本方案还设置有杀菌增压单元，既可以通过臭氧来实现对自来水进行消毒杀菌的功能，还可以通过臭氧转化而成的氧气来实现对储水器内的水进行加压的功能，而现有技术中加压都是采用增压泵，本基础方案无需采用增压泵即可达到增压的目的。本方案杀菌增压单元还能实现臭氧、氧气的循环使用，氧气在对储水器中的水增压后还可通过输气管进入到软水单元中继续进行消毒杀菌。The beneficial effect of this basic scheme is that compared with the prior art, the tap water is purified from the source of domestic water, which solves the problem that all domestic water cannot be purified in the prior art. At the same time, this scheme also achieves the purpose of softening tap water, removing calcium and magnesium ions in tap water, and using softened water to wash clothes will not cause the clothes to become hard after drying. Scale will be generated, which prolongs the service life of the electric water heater. This solution is also equipped with a sterilization pressurization unit, which can not only realize the function of disinfecting tap water through ozone, but also realize the function of pressurizing the water in the water storage device through the oxygen converted from ozone. In the prior art, a booster pump is used for pressurization, but this basic scheme can achieve the purpose of boosting without using a booster pump. The sterilizing supercharging unit of this scheme can also realize the cyclic use of ozone and oxygen, and the oxygen can also enter the soft water unit through the air pipe to continue to sterilize after the water in the water storage is pressurized.

The water inlet of the PP cotton filter 1 is connected to the tap water main water pipe at home, and the tap water flows into the activated carbon filter 2 after preliminary purification by the PP cotton filter 1, and the activated carbon KDF filter 3 further purifies the tap water, Then it flows into the KDF filter 3, and the KDF filter 3 can remove some heavy metal ions and some bacteria in the water. The above three kinds of KDF filters 3 not only purify tap water, but also reduce the purification difficulty of the subsequent water softening unit and water purification unit, and improve the service life of the water softening unit and water purification unit. The tap water flows into the ion exchange resin water softening device 4 after passing through the KDF filter 3 to remove calcium ions and magnesium ions in the tap water. A first electromagnetic valve 16 is also arranged between the ion exchange resin water softening device 4 and the KDF filter 3 , and an ultraviolet lamp 9 and a liquid level sensor 8 are also arranged inside it. The ion-exchange resin water softening device 4 is provided with a first water outlet 10 and a second water outlet 11, the first water outlet 10 is connected to the ultrafiltration membrane water purifier 5, and the second water outlet 11 is connected to the home water heater, toilet and laundry grooved pipes. The tap water flows from the first water outlet 10 into the ultrafiltration membrane water purifier 5 for further purification treatment, and finally flows into the water reservoir 6 for storage. A second solenoid valve 17 is provided between the water storage 6 and the ultrafiltration membrane water purifier 5 . A sterilizing booster unit is also arranged in parallel on the pipeline between the ion exchange resin water softening device 4 and the water storage 6 .

The high-pressure gas storage device 7 is communicated with the ion exchange resin water softening device 4 through the air outlet pipe 14, and is communicated with the water reservoir 6 through the air inlet pipe 15. The air outlet pipe 14 is provided with a heating device 12, and the heating device It is a gas heating wire, and the air intake pipe 15 is provided with a fourth solenoid valve 19 . The high-pressure gas storage device 7 is also filled with oxygen. The first electromagnetic valve 16, the second electromagnetic valve 17, the third electromagnetic valve 18, the fourth electromagnetic valve 19, the gas heating wire, the ultraviolet lamp 9 and the signal collector are electrically connected with the control device respectively, and the signal collector can The signal sent by the liquid level sensor 8 is sensed.
具体实施时，先在高压储气装置7中充满高压氧气，同时第一电磁阀16、第二电磁阀17、第三电磁阀18和第四电磁阀19全部处于阀门开启状态。自来水经过PP棉过滤器1、活性炭过滤器2和KDF过滤器3，再流动到离子交换树脂软化水装置4中进行钙镁离子的去除。高压储气装置7中的氧气无法从出气管进入到离子交换树脂软化水装置4中，只能通过进气管15进入到储水器6中，再通过输气管13进入到离子交换树脂软化水装置4中。氧气经过紫外线灯9的照射形成臭氧，臭氧对离子交换树脂软化水装置4中的自来水进行杀菌消毒，臭氧在进行消毒杀菌之后进入出气管14，经过出气管14上的气体电热丝加热后逐渐分解为氧气，再进入到高压储气装置7中，臭氧分解为氧气会增大气体体积，对后续加压有增强的作用。经过预处理、钙镁离子去除和消毒杀菌的自来水一部分通过第一出水口10流动到超滤膜净水器5中进行下一步净化，另一部分通过第二出水口11流动到家中热水器、卫生间和洗衣槽的水管中。日常洗衣、洗漱对水质的要求相比厨房对水质的要求而言要低一些，经过上述步骤的净水后，自来水就可以直接用于洗衣、洗漱，洗出的衣服不会产生硬化的现象、电热水器也不会产生水垢，用于洗漱也不会对人体产生不良影响。自来水通过第一出水口10后进入到超滤膜净水器5中再净化，最后流入到储水器6中储存起来，储水器6的出水端连通到厨房用水的水管。用户在使用厨房用水时，由于自来水通过超滤膜后压力下降，导致自来水的流量下降，会产生水流变小的问题，此时通过控制柜关闭第三电磁阀18，大量氧气进入储水器6中，对储水器6中的水加压，增大厨房用水的流量，便于洗菜做饭。本方案为了防止自来水进入到输气管13，出气管14中，还在离子交换树脂软化水装置4中设置有液位传感器8，当自来水液位达到警戒线，液位传感器8会发出信号，与之匹配的信号收集器采收到信号后传输给控制柜，控制柜会关闭第一电磁阀16防止自来水进入到输气管13和出气管14中。During specific implementation, the high-pressure gas storage device 7 is first filled with high-pressure oxygen, and at the same time, the first solenoid valve 16, the second solenoid valve 17, the third solenoid valve 18 and the fourth solenoid valve 19 are all in the valve open state. The tap water passes through the PP cotton filter 1, the activated carbon filter 2 and the KDF filter 3, and then flows into the ion exchange resin water softening device 4 to remove calcium and magnesium ions. The oxygen in the high-pressure gas storage device 7 cannot enter the ion exchange resin water softening device 4 from the air outlet pipe, but can only enter the water storage device 6 through the air inlet pipe 15, and then enter the ion exchange resin water softening device through the gas delivery pipe 13 4 in. Oxygen is irradiated by the ultraviolet lamp 9 to form ozone, and the ozone sterilizes the tap water in the ion exchange resin water softening device 4, and the ozone enters the air outlet pipe 14 after being sterilized, and gradually decomposes after being heated by the gas heating wire on the air outlet pipe 14 It is oxygen, and then enters the high-pressure gas storage device 7, and the decomposition of ozone into oxygen will increase the volume of the gas, which will enhance the subsequent pressurization. Part of the tap water through pretreatment, calcium and magnesium ion removal and disinfection flows into the ultrafiltration membrane water purifier 5 through the first water outlet 10 for further purification, and the other part flows through the second water outlet 11 to the water heater, toilet and In the water pipe of the laundry trough. The water quality requirements for daily laundry and washing are lower than those for kitchens. After the above steps of water purification, tap water can be used directly for laundry and washing, and the washed clothes will not harden. The electric water heater will not produce scale, and it will not have adverse effects on the human body when used for washing. The tap water enters the ultrafiltration membrane water purifier 5 for further purification after passing through the first water outlet 10, and finally flows into the water storage device 6 for storage, and the water outlet end of the water storage device 6 is connected to the water pipe for kitchen water. When the user uses water for the kitchen, the pressure of the tap water drops after passing through the ultrafiltration membrane, resulting in a drop in the flow rate of the tap water, which will cause the problem that the water flow becomes smaller. At this time, the third electromagnetic valve 18 is closed through the control cabinet, and a large amount of oxygen enters the water storage 6 In, pressurize the water in the water reservoir 6 to increase the flow of kitchen water, which is convenient for washing vegetables and cooking. In order to prevent tap water from entering the gas delivery pipe 13 and the gas outlet pipe 14, a liquid level sensor 8 is also arranged in the ion exchange resin water softening device 4 in this program. When the tap water liquid level reaches the warning line, the liquid level sensor 8 will send a signal to communicate with The matched signal collector transmits the signal to the control cabinet after receiving the signal, and the control cabinet will close the first electromagnetic valve 16 to prevent tap water from entering the gas delivery pipe 13 and the gas outlet pipe 14 .
