Embodiment
As Fig. 2, Fig. 3, shown in Figure 4, a kind of water-saving pure water making system includes reverse osmosis membrane filt, pure water outlet pipeline, condensed water discharge pipe and former water suction culvert that blowdown system is controlled in the pure water water quality detection.Former water suction culvert, pure water outlet pipeline, condensed water discharge pipe are connected with import, outlet and the condensed water discharge outlet of reverse osmosis membrane filt respectively.Former water suction culvert includes former water inlet control device, former water prefilter, former water water sending device serial connection forms.Former water inlet control device and water sending device in the present embodiment are selected booster water pump and entering water electromagnetic valve respectively for use.Former water suction culvert in the present embodiment is formed through the water pipe serial connection successively by one-level prefilter, pressure switch, entering water electromagnetic valve, secondary prefilter, three grades of prefilters, booster water pumps.Certain former water suction culvert each several part order of connection is not unique, can adopt different serial connection modes as required yet, and the prefilter number also can be provided with as required.The pure water outlet pipeline is divided into two, and one the tunnel connects water butt, and another road is through the outlet of a post-filter as pure water.
The condensed water discharge pipe is divided into two, and a branch road is that check valve is connected with former water suction culvert with throttling valve or its one-way throttle valve of forming one, and another branch road is provided with a discharge solenoid valve.Condensed water return line one end is connected with the condensed water discharge outlet of reverse osmosis membrane filt in the present embodiment, and the other end inserts the booster water pump entrance end through the one-way throttle valve of check valve and throttling valve or its composition one.Certainly condensed water return line and former water suction culvert link position are not unique, can be connected between secondary prefilter and three grades of prefilters yet and wait other positions.In order to guarantee that condensed water can only flow back to former water suction culvert by return line, present embodiment is provided with a check valve on return line.Described water quality detection control blowdown system includes discharge solenoid valve, discharge solenoid valve pilot circuit and water quality detection probe, and the water quality detection probe is located on the pure water outlet pipeline.The water quality detection probe is two metal electrodes.Discharge solenoid valve is located on branch road of condensed water discharge pipe, and two metal electrodes of water quality detection probe insert pure water outlet pipeline the inside.For easy to use, two metal electrodes being arranged in parallel and being fixed on one is on the "T"-shaped pure water thrust-augmenting nozzle, and an end of metal electrode passes the thrust-augmenting nozzle sidewall and stretches in the thrust-augmenting nozzle, and the other end is electrically connected with the discharge solenoid valve pilot circuit.
The schematic circuit of discharge solenoid valve pilot circuit as shown in Figure 3, this discharge solenoid valve pilot circuit includes booster water pump high-low level sampling unit, the discharge solenoid valve power supply amplifies driver element and main control chip.Two metal electrodes of water quality detection probe are connected with main control chip respectively.Booster water pump high-low level sampling unit is serially connected between booster water pump positive source and the main control chip pin.Main control chip in the present embodiment is a programmable cpu.Two pressure switches of serial connection on the supply lead of booster water pump, entering water electromagnetic valve is in parallel with booster water pump.These two pressure switches are located at respectively on former water suction culvert and the pure water outlet pipeline.Former water suction culvert pressure switch has only when pressure is enough, just conducting.Just conducting when the pressure switch on the pure water outlet pipeline has only pressure not enough.Have only two pressure switches so all during conducting, booster water pump and entering water electromagnetic valve could works better.Booster water pump high-low level sampling unit is given main control chip with booster water pump power level feedback of status, and main control chip detects booster water pump and is in charged working order, and promptly during booster water pump positive source high level, entire circuit is in running order.The discharge solenoid valve power supply amplifies driver element and is connected between the supply lead and main control chip of discharge solenoid valve.The resistance value of pure water can reduce along with the raising of foreign matter content, and condensed water is through after the recycled for multiple times, and its foreign matter content will reach certain value and become concentrated waste water.The water quality detection probe detects the resistance value of pure water in real time, and the resistance value signal is delivered to main control chip, main control chip compares pop one's head in detected resistance value and preset value of water quality detection, if resistance value is less than preset value, the foreign matter content that pure water is described is above standard, this moment, main control chip was powered to discharge solenoid valve by discharge solenoid valve power supply amplification driver element, will cross concentrated waste water and in time emit.Cross and concentrate discharge of wastewater after for some time, prepared pure water foreign matter content reduces again, and main control chip stops to the discharge solenoid valve power supply, and discharge solenoid valve is closed.The time that discharge solenoid valve is opened can be set.
Workflow of the present invention as shown in Figure 4, during lack of water, i.e. during the pressure switch conducting on the pure water outlet pipeline, the energising of pure water water manufacturing system is in running order in the water butt.Former water washed reverse osmosis membrane 10 seconds through booster water pump, and the waste water after the flushing emits through discharge solenoid valve.After flushing finished, discharge solenoid valve was closed, and the pure water water manufacturing system begins to make pure water.Make when the water is just on the boil begins, the TDS value of pure water can be lower than set(ting)value, and at this moment, discharge solenoid valve is in closing condition, and condensed water flows back to the reverse osmosis membrane entrance end through return line and utilizes again.After after a while, the TDS value of pure water will meet or exceed set(ting)value, and discharge solenoid valve pilot circuit control this moment discharge solenoid valve is opened to discharge in 5～7 seconds and concentrated waste water.The present invention makes after the water time is added to 8 hours, flushing reverse osmosis membrane 60 seconds, cumulative time zero clearing.After water butt water was full, pressure switch was closed, and the outage of pure water water manufacturing system stops to make water.
Time set in the workflow diagram of the present invention is not unique, specifically can do necessary adjustment according to practical situation.
