Accompanying drawing explanation
Figure 1 shows that structural representation of not shutting down medical purification of water device of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, of the present utility modelly do not shut down medical purification of water device and comprise successively the raw water box 1 being communicated with, raw water pump 2, the plate-type heat exchanger 3 that the Boiler Steam of take is thermal source, more medium filter 4, activated charcoal filter 5, accurate filter 6, one-level frequency conversion high-pressure pump 7, one-level RO device 8, intermediate water tank 9, the second high-pressure pump 10, secondary RO device 11, and pure water tank 12, the water inlet of described raw water box connects tap water, on the pipeline of described raw water pump water outlet, draw and be connected to flocculation chemicals dosing plant 13, on the pipeline of described accurate filter water-in side, draw and be connected to Scale inhibitors chemicals dosing plant 14, on the pipeline of the second described high-pressure pump water-in side, draw and be connected to pH regulator device 15, also comprise the backwashing pump 16 being communicated with described raw water box, the water outlet of described backwashing pump is connected to the backwash mouth of more medium filter and activated charcoal filter, the sterilization water port of described activated charcoal filter is communicated to raw water box and is provided with valve on the first described return line through the first return line, the backwash of more medium filter and activated charcoal filter when normal operation, the wash water discharge, only have activated charcoal filter just through a return line 17, to be back to raw water box when utilizing pasteurized water to carry out disinfection.Effectively save the use of medicine, improved producing water ratio.The product water side of described one-level RO device is connected to intermediate water tank after one-level T-valve, described and the dense water side of RO device and another valve port of one-level T-valve are connected to respectively return line 18 by the road, the product water side of described secondary RO device is through secondary T-valve access pure water tank, the dense water side of described secondary RO device is connected to raw water box through the second return line 19, and another valve port of described secondary T-valve is connected to intermediate water tank through pressure relief pipe 20.After raw water pump, adding plate-type heat exchanger can guarantee: 1, in normal operation, by controlling vapour source, former water is being heated to 25 ℃, because reverse osmosis water production rate and ratio of desalinization in 25 ℃ are best; 2, in pharmaceutical industries, activated charcoal filter is using certain all after dates need to carry out pasteurization, at this time needs water to be heated to 85 ℃ to gac sterilization, the activity of activity recovery charcoal.
The other discharge branch road 21 that is connected on the second described return line, and be provided with bleed valve thereon, one-level frequency conversion high-pressure pump of the present utility model and secondary frequency conversion high-pressure pump have all adopted with variable frequency starting, can reduce like this high-pressure pump pressure when moment starts and cross conference to RO film is caused to permanent destruction.When in system, pure water tank arrives a high position simultaneously, secondary frequency conversion high-pressure pump is produced water with 25Hz operation and secondary RO device and is got back to intermediate water tank, concentrated water discharge is to raw water box, when secondary being detected, produces water or dense water power and leads and produce the defective bleed valve of water when defective and open discharge; When intermediate water tank arrives when high-order, one-level frequency conversion high-pressure pump is produced water with 25Hz operation and one-level RO device and is all got back to raw water box with concentrated water discharge, when one-level product water power being detected, leads and produces the defective bleed valve of water when defective and open discharge.In system, carry out not shutting down for 24 hours in service, in pipeline, do not have stagnant water, in water body flow, be not easy to produce water bacteria and pollute pipeline and membrane element.
Described flocculation agent chemicals dosing plant, Scale inhibitors chemicals dosing plant and pH regulator device, all similarly to the prior art, the pencil that it comprises respectively tank body, volume pump and access pipeline, no longer specifically describes at this.Specifically, quartz filter is mainly in order to remove impurity in sewage, absorption wet goods, water quality is met the requirement recycling.Activated charcoal filter, for adsorbing the chlorine residue that more medium filter cannot be removed, can effectively guarantee rear class service life of equipment, improves effluent quality, prevents from polluting, and particularly prevents rear class reverse osmosis membrane, and the remaining oxygen intoxication of free state of ion exchange resin etc. is polluted.Also adsorb from prime simultaneously and leak the pollutants such as small organic molecule of coming, peculiar smell, colloid and pigment, heavy metal ion etc. in water are had to obvious Adsorption effect, also there is the effect that reduces COD, can further reduce the SDI value of RO water inlet, guarantee SDI<5, TOC<2.Oppm.Charcoal filter adopts the design of hydraulic simulation major diameter, and adopts particle diameter reasonable, and specific surface area is greater than the highly effective active carbon of 1000 ㎡/g.Accurate filter is used for holding back molecule; the RO device of protection rear class; the filter core material of accurate filter has poly-tetrem alkene, polysulfones, nylon, polypropylene, cellulose acetate; pore size filter has: 0.1 μ m, 0.22 μ m, 1 μ m, 3 μ m, 5 μ m, 10 μ m etc., it is the polypropylene of 5 μ m that the utility model is selected pore size filter.RO device, it is reverse osmosis unit using membrane separating technology, adopting aperture is the reverse osmosis membrane (RO film) of 1/10000 μ m, make the water of higher concentration become low concentration of water, can effectively remove charged ion, inorganics, colloidal particle, bacterium and the organic substance etc. in water, thereby reach physical and chemical index and the hygienic standard of drinking regulation simultaneously.The ratio of desalinization of reverse osmosis membrane improves, and the rate of recovery is high, in desalination, also by the organic matter removal of most of bacterium, colloid and macromolecule, makes effluent quality meet GB.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
