Description
技术领域technical field
本发明涉及一种净水机，尤其涉及了一种密闭承压式RO反渗透净水机及其浓缩水回收存储装置。The invention relates to a water purifier, in particular to a closed pressure-bearing RO reverse osmosis water purifier and a concentrated water recovery and storage device thereof.
背景技术Background technique
我国是水资源贫乏的国家，我国人口占世界的22％，淡水仅占世界的6％，人均水资源2200立方米，约为世界人均水平的1/4，因此节水对我国来说有着特别重要的意义。my country is a country with poor water resources. my country's population accounts for 22% of the world's total, fresh water accounts for only 6% of the world's total, and the per capita water resource is 2,200 cubic meters, which is about 1/4 of the world's per capita level. Therefore, water conservation has special significance for our country Significance.
然而目前，市场上所有正在使用及正在销售的密闭承压式RO反渗透净水机在制纯水的同时会产生浓缩水，即所谓的“废水”，而浓缩水就是市政自来水经过密闭承压式RO反渗透净水机前三级后，在RO反渗透膜过滤掉的透过水，密闭承压式RO反渗透净水机的浓缩水由于已经经过三道处理，因此，除了含盐量比自来水略高(约为自来水的1.3倍)，其他大多数指标，如浊度、色度、余氯、嗅和味、有机物、悬浊物、胶体等等，所以将浓缩水排放造成了水资源的严重浪费。However, at present, all the closed pressurized RO reverse osmosis water purifiers currently being used and sold on the market will produce concentrated water, the so-called "waste water", while producing pure water, and the concentrated water is municipal tap water that is sealed and pressurized. After the first three stages of the RO reverse osmosis water purifier, the permeated water filtered by the RO reverse osmosis membrane, and the concentrated water of the sealed pressure-bearing RO reverse osmosis water purifier have been treated in three ways. Therefore, in addition to the salt content Slightly higher than tap water (about 1.3 times that of tap water), most other indicators, such as turbidity, chromaticity, residual chlorine, smell and taste, organic matter, suspended solids, colloids, etc., so the discharge of concentrated water causes water pollution Serious waste of resources.
现阶段随着人们生活质量的进一步提高及改善，节约及环保意识的增强和提高，以及人们对环境及水资源有了充份的认知和理解，因而对节能减排及水资源的综合利用提出了更高的要求。而目前市场上存在的微废水RO反渗透净水机，只是在某种程度上降低了RO反渗透净水机浓缩水的排放量，并没有严格意义上的真正做到浓缩水的综合利用，没有做到真正的零排放。At this stage, with the further improvement and improvement of people's quality of life, the enhancement and improvement of conservation and environmental protection awareness, and people's full awareness and understanding of the environment and water resources, so the comprehensive utilization of energy saving and emission reduction and water resources put forward higher requirements. However, the micro-wastewater RO reverse osmosis water purifiers currently on the market only reduce the discharge of concentrated water from RO reverse osmosis water purifiers to a certain extent, and do not really achieve comprehensive utilization of concentrated water in a strict sense. No real zero emissions.

自来水进水管2与压力感应开关8的出水口连接的管路上设有逆止阀10，水流只能从自来水进水管2流向浓缩水水龙头4，压力感应开关8的出水口与浓缩水出水管15连接的管路上设有逆止阀10，水流只能从压力感应开关8流向浓缩水水龙头4。与自来水进水管2连接的自来水总管路上通过第二三通13分别连接两根分水管，其中一根为自来水出水管16，其与滤芯1的进水口连接，另一根与与压力感应开关6的出水口连接，逆止阀10设置在与压力感应开关6的出水口连接的分水管上。A non-return valve 10 is provided on the pipeline connecting the tap water inlet pipe 2 and the outlet of the pressure sensor switch 8, the water flow can only flow from the tap water inlet pipe 2 to the concentrated water faucet 4, and the outlet of the pressure sensor switch 8 is connected to the concentrated water outlet pipe 15 A check valve 10 is provided on the connected pipeline, and the water flow can only flow from the pressure sensing switch 8 to the concentrated water faucet 4 . On the tap water main pipeline connected with the tap water inlet pipe 2, two water distribution pipes are respectively connected through the second tee 13, one of which is a tap water outlet pipe 16, which is connected with the water inlet of the filter element 1, and the other is connected with the pressure sensor switch 6 The water outlet is connected, and the check valve 10 is arranged on the water distribution pipe connected with the water outlet of the pressure sensor switch 6 .
水泵6的出水口与储水桶7的入水口连接的管路上设有逆止阀10。该逆止阀10可防止抽入储水桶7内的水回流，以保证储水桶7内的压力值。A non-return valve 10 is provided on the pipeline connecting the water outlet of the water pump 6 with the water inlet of the water storage bucket 7 . The non-return valve 10 can prevent the water pumped into the water storage barrel 7 from flowing back, so as to ensure the pressure value in the water storage barrel 7 .
本实施例在具体操作时，自来水通过自来水进水管2到第二三通13，第二三通13将自来水总管路分成两根分管路，经过电磁阀9的水流入滤芯1的进水口、经过逆止阀10的水连接至浓缩水水龙头4；经滤芯1净化后的纯水经纯水出水口流至纯水水龙头3，滤芯1产生的浓缩水通过水流开关，经水泵6抽入储水桶7。In the specific operation of this embodiment, the tap water passes through the tap water inlet pipe 2 to the second three-way 13, and the second three-way 13 divides the main tap water pipeline into two sub-pipelines, and the water through the electromagnetic valve 9 flows into the water inlet of the filter element 1, passes through The water from the check valve 10 is connected to the concentrated water faucet 4; the pure water purified by the filter element 1 flows to the pure water faucet 3 through the pure water outlet, and the concentrated water generated by the filter element 1 passes through the water flow switch and is pumped into the water storage tank by the water pump 6 7.
当储水桶7内浓缩水的水位逐渐上升的过程中，水位上升，压缩储水桶7内的空气，当压力达到压力感应开关8所设定的上限值后，压力感应开关8断开，水泵6停止工作，因为压力感应开关8与电磁阀9为串联连接，所以电磁阀9同时断开停止给滤芯2供水，并使滤芯1停止工作；当储水桶7内压力低于压力感应开关8设定的上限值时，电磁阀9打开，滤芯1可开始正常制纯水；当储水桶7水满无法制纯水时，打开打开浓缩水水龙头4处的龙头阀门使用至水压降至压力感应开关8设定值以下时，电磁阀9打开，滤芯1正常工作。When the water level of the concentrated water in the water storage tank 7 gradually rises, the water level rises and compresses the air in the water storage tank 7. When the pressure reaches the upper limit set by the pressure sensor switch 8, the pressure sensor switch 8 is disconnected, and the water pump 6 stop working, because the pressure sensing switch 8 and the solenoid valve 9 are connected in series, so the solenoid valve 9 is disconnected at the same time to stop the water supply to the filter element 2, and the filter element 1 stops working; when the pressure in the water storage tank 7 is lower than the pressure sensing switch 8 When the upper limit value is set, the solenoid valve 9 is opened, and the filter element 1 can start to make pure water normally; when the water storage tank 7 is full and cannot make pure water, open the faucet valve at the 4 place of the concentrated water faucet and use it until the water pressure drops to pressure When the set value of the induction switch 8 is below, the electromagnetic valve 9 is opened, and the filter element 1 works normally.
当打开浓缩水水龙头4处的龙头阀门时，储水桶7靠压缩空气将水反压至浓缩水水龙头4，而当储水桶7水无法供应时，其中自来水通过自来水进口2经过逆止阀10补充至浓缩水水龙头4。When the faucet valve at the concentrated water faucet 4 is opened, the water storage tank 7 backpressures the water to the concentrated water faucet 4 by compressed air, and when the water in the water storage tank 7 cannot be supplied, the tap water is replenished through the tap water inlet 2 through the check valve 10 To concentrated water tap 4.
由于在自来水进水管2与浓缩水水龙头4连接的管路以及自来水进水管2与压力感应开关8的出水口连接的管路上均设有逆止阀10，所以浓缩水不会进入自来水管道，自来水也不会进入储水桶7。Owing to being provided with check valve 10 on the pipeline that tap water inlet pipe 2 is connected with concentrated water faucet 4 and the pipeline that tap water inlet pipe 2 is connected with the water outlet of pressure sensor switch 8, so concentrated water can not enter tap water pipeline, tap water Can not enter water storage bucket 7 either.
当储水桶7出现压力过高时，打开储水桶7底部的泄压阀11，泄压阀11的压力值大于压力感应开关8设定的上限值，以达到对储水桶7的保护功能。When the pressure of the water storage tank 7 is too high, the pressure relief valve 11 at the bottom of the water storage tank 7 is opened.
总之，以上所述仅为本发明的较佳实施例，凡依本发明申请专利范围所作的均等变化与修饰，皆应属本发明专利的涵盖范围。In a word, the above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the patent of the present invention.
