Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1, a kind of ultrapure water production system, comprise the preprocessing subsystem 1, reverse osmosis subsystem 2 and the mixed bed subsystem 3 that connect successively, wherein preprocessing subsystem 1 comprises the raw water box 11, raw water pump 12, more medium filter 13, activated charcoal filter 14 and the cartridge filter 16 that connect successively; Wherein, raw water box 11 comprises inner bag 112, base 114 and is set in the shell 111 be connected on inner bag 112 and with base 114, the base 114 of raw water box 11 is also provided with and can limits the sheath 113 that inner bag 112 touches shell 111, sheath 113 is between shell 111 with inner bag 112 and be connected with base 114, such sheath 113 just limits the distortion of inner bag 112, avoid inner bag 112 to extrude shell 111 and produce noise, there is extraordinary effect.Sheath 113 welds with base 114 or is screwed, and sheath 113 is iron net or steel mesh, can reduce the weight of raw water box 11 like this, sheath 113 is provided with some stiffening webs 1131, ensure that the structural strength of sheath 113.
Reverse osmosis subsystem 2 comprises the one-level high-pressure pump 21, first-stage reverse osmosis device 22, secondary high-pressure pump 23 and the second level reverse osmosis apparatus 24 that connect successively, the setting of one-level high-pressure pump 21 and secondary high-pressure pump 23 is the pressure in order to make the water inlet of reverse osmosis reach certain, allow reverse osmosis process be carried out, in first-stage reverse osmosis device 22 and second level reverse osmosis apparatus 24, include multilayer reverse osmosis membrane; Mixed bed subsystem 3 comprises the mixed bed device 31, ultraviolet sterilizer 32 and the raw water box 11 that connect successively.In order to strengthen the pretreating effect of former water, namely the impurity in the former water of further filtering, be provided with between raw water pump 12 and more medium filter 13 and add flocculation agent device 121, be also disposed with between activated charcoal filter 14 and softening agent and add reductive agent device 141 and add Scale inhibitors device 142.
Containing plurality of impurities in former water, as suspended substance, colloid, organism and inorganics, in use, former water before being extracted out by raw water pump 12 and entering more medium filter 13 from raw water box 11, in former water, polymeric flocculant is added or composite flocculation agent (such as quaternary amine type polyacrylamide) is hydrolyzed in water from adding flocculation agent device 121, charged molecule long-chain can be formed like this, and at long-chain two ends absorption colloid, thus formation large granular impurity is beneficial to filtering, to ensure that more medium filter 13 more effectively removes the colloid in water.In addition, in the process of flocculation, partial organic substances can be flocculated thing and absorb.
The former water entering more medium filter 13 can be filtered for the first time, and the filtrate in more medium filter 13 comprises the quartz sand of five kinds of specifications, for remove suspended substance in former water and de-steady after colloid.
Former water can enter activated charcoal filter 14 after more medium filter 13, refining shell mould gac is filled with in activated charcoal filter 14, for adsorbing chlorine residue in former water, organism, partial pigment and objectionable impurities, prevent reverse osmosis subsystem 2 from being polluted.
Then before Yuan Shui enters cartridge filter 16, in former water, reductive agent and Scale inhibitors is added successively by adding reductive agent device and adding Scale inhibitors device 142, because reverse osmosis membrane is made up of aromatic polyamides composite membrane, not resistance to oxidation, reductive agent by the Reduction of Oxide in water, can run to ensure that reverse osmosis unit is steady in a long-term; Scale inhibitors can stop the fouling of vitriol, and to prevent the materials such as calcium sulfate to the harm of reverse osmosis unit, particularly barium sulfate crystallographic is to the harm of reverse osmosis unit.
Cartridge filter 16 belongs to microfiltration equipment, safety effect is played in preprocessing subsystem 1, check on when more medium filter 13 working state abnormal, for ensureing can both to provide qualified water supply in any case, cartridge filter 16 as last filtration unit, in anti-sealing and ducted particulate enter reverse osmosis subsystem 2.
In addition, by being provided with PH setting device 221 between first-stage reverse osmosis device 22 and secondary high-pressure pump 23, realize the pH value (being generally pH=8.3) regulating first-stage reverse osmosis device 22 to intake, CO2 is converted into HCO3-, in first-stage reverse osmosis device 22, remove HCO3-, thus reach reduction CO2 content.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
