Detailed description of the invention
The present invention is described further below in conjunction with the accompanying drawings.
Accompanying drawing is a kind of specific embodiment of the present invention: the built-in system cleaning sterilizing device of ultrapure water machine, including passing through
The tap water inlet valve 1 that pipeline is sequentially connected with, activated carbon cartridge filter 2, high-pressure pump 3, reverse osmosis unit 4, in order to hold
The pure water tank 5 of pure water is prepared through reverse osmosis unit 4.Dense water during reverse osmosis unit 4 Pure-water Making, i.e. waste water is via dense water
The output of discharge loop.
Arrange pure water tank floor drain valve 12 in the bottom of pure water tank 5, pure water tank floor drain valve 12 is after discharging sterilization
Waste water；Be sequentially connected with pure water circulating pump 6 and check valve 7 in pure water tank 5 rear class, the rear class of check valve 7 respectively and connect press packet 8,
Ultra-pure water valve 9 and wash-out valve 10.Pure water circulating pump 6 is for the pressurization at rear class water, and a portion pure water is through adding
Pressure enters into press packet 8, and press packet 8 is in order to assist output High Pressure Pure Water, it is possible to reduce the start-stop frequency of water-circulating pump 6.
Ultra-pure water valve 9 enters into the pipeline of rear class for controlling ultra-pure water, and in accompanying drawing, ultra-pure water is through ultra-pure water valve
9 enter mixed bed 11, water quality testing meter, and then arrive ultra-pure water use point.
The output of wash-out valve 10 is connected between tap water inlet valve 1 and activated carbon cartridge filter 2, wash-out valve
10 together with activated carbon cartridge filter 2, high-pressure pump 3, reverse osmosis unit 4, pure water tank 5 and pure water circulating pump 6, check valve 7 shape
Become an airtight closed circuit, beneficially disinfectant solution circulation wherein.
Said structure parts can use PU to carry out socket connection, it would however also be possible to employ rustless steel welds.
Preferably, between reverse osmosis unit 4 and pure water tank 5, setting can detect water intermediate ion concentration or organic concentration
Water quality probe.So control device and can make various control, it is achieved disinfecting process according to the detection data of water quality probe
Automatization.
Further, pressure transducer is set between high-pressure pump 3 and reverse osmosis unit 4, in order to detect the water outlet of high-pressure pump 3
Pressure.
Between pure water tank 5 and pure water circulating pump 6, pressure transducer is set, in order to detect the pure water pressure of pure water tank 5.
Between tap water inlet valve 1 and activated carbon cartridge filter 2, pressure transducer is set, in order to detect former water
Pressure.
Pressure transducer is in order to the pressure signal of signal piping, it is provided that to control unit, in order to realizes corresponding control and moves
Make.
Convenient control, described pure water tank floor drain valve 12 and wash-out valve 10 are electromagnetic valve.After using electromagnetic valve, can
To be controlled by electric signal, reduce participating in of people.
Concrete operations are explained in detail below as follows:
When controlling the water circulation is to certain time, or after detection poor water quality, need the built-in system to ultrapure water machine to clean and disappear
Poison.
First, tap water inlet valve 1, ultra-pure water valve 9 being closed, high-pressure pump 3 power-off is out of service.At pure water tank 5
Interior addition disinfectant solution, opens wash-out valve 10, starts pure water circulating pump 6 and starts working, and disinfectant enters press packet 8, and passes through
Wash-out valve 10, enters activated carbon cartridge filter 2, enters reverse osmosis unit 4, pure water tank afterwards through the space of high-pressure pump 3
5, through the sterilization of about 10-30 minute, pure water tank floor drain valve 12 and tap water inlet valve 1 to be opened, high-pressure pump 3 is energized
Running, now, on the one hand the waste water in disinfecting process is got rid of via pure water tank floor drain valve 12, and on the other hand, ultrapure water machine is opened
Begin normally to produce ultra-pure water, the waste water in ultra-pure water mixing disinfecting process, participate in wash-out valve 10 and filter together with activated carbon security personnel
Device 2, high-pressure pump 3, reverse osmosis unit 4, pure water tank 5 and pure water circulating pump 6, check valve 7 form an airtight closed circuit
In.
Because of the addition of ultra-pure water, the disinfectant solution in above-mentioned closed circuit is constantly diluted, and through pure water tank floor drain
Valve 12 is constantly got rid of.Through a period of time, after water quality detection is qualified, then wash-out valve 10 is closed, by 9 dozens, ultra-pure water valve
Opening, ultra-pure water can enter next stage and use, and now a disinfecting process completes.
Whether in disinfecting process, staff takes off pure water tank 5 lid, is positioned over home, observe in pure water tank 5
There is enough liquid, need to be more than or equal to the 2/3 of pure water tank 5 total height, if after the equipment product full water such as liquid level is less than this value, need
It is carried out disinfection again.There is no enough liquid in pure water tank 5, influence whether the properly functioning of pure water circulating pump 6, can shadow
Ring the quality and quantity to disinfectant solution, directly influence this cleaning and sterilizing effect, ultimately result in overproof water quality.
By a certain percentage disinfectant solution is put in solvent pure water case 5, when throwing in disinfectant solution, should be noted the distance with liquid level, no
Preferably away from too far away, in order to avoid liquid splashes the place beyond pure water tank 5, dry with the article cleaning of neat and tidy the most in time if any spilling
Only, normally work with exempt from customs examination and be negatively affected.
Being above being described in detail a kind of specific embodiment structure provided by the present invention, the present embodiment is simply used
In helping to understand method for designing and the core concept of the present invention, to those skilled in the art, set according to the thought of the present invention meanwhile
The essence of meter is identical, all within scope.
