Description
Technical field
The present invention relates to a kind of reusable accurate filter and reverse osmosis system take reverse osmosis concentrated water as wash-down water.
Background technology
Seawater is very high owing to its saltiness, and can not directly be used, and two kinds of methods of main employing desalinize seawater at present, i.e. distillation method and reverse osmosis method.Distillation method mainly is used to super-huge sea water desaltination and processes place upper and that heat energy is abundant, very wide of reverse osmosis membrane applicable surface, and ratio of desalinization is very high, therefore be widely used, reverse osmosis membrane at first is that seawater is extracted up, carry out preliminary treatment, reduce turbidity of sea water, prevent bacterium, the microbial growths such as algae, then use the supercharging of Special high-voltage pump, make seawater enter reverse osmosis membrane, because the seawater saltiness is high, so seawater reverse osmosis membrane must have equipment with high desalinization, corrosion-resistant, high pressure resistant, the characteristics such as antipollution, through the seawater after the reverse osmosis membrane processing, its saltiness reduces greatly, and TDS content is down to about 700 mg/litre from 36000 mg/litre.Water quality after the desalination even be better than tap water so just can be for industry, commercial, resident and boats and ships, naval vessels.Reverse osmosis system is through fine filter with former water; the seed activity carbon filter; compression charcoal filter etc.; pressurize by pump again; utilize reverse osmosis membrane; make the water of higher concentration become low concentration of water; simultaneously with industrial pollutants; heavy metal; bacterium; the impurity that virus etc. is sneaked in the water is in a large number all isolated; thereby reach physical and chemical index and the hygienic standard of drinking regulation; output is to clear to pure water; the optimal selection that human body in time replenishes high-quality moisture content. because the water purity of RO reverse osmosis technology production is the highest in the cutting water technology that the mankind grasp at present; cleanliness factor almost reaches 100%, so people claim that this machine for producing water device is the reverse-osmosis pure water machine.The reverse osmosis system using membrane separating technology can be removed charged ion, inorganics, colloidal particle, bacterium and organic substance etc. in the water effectively.And at present, existing accurate filter is owing to after the long-term work, make easily filter core stop up and cisco unity malfunction, renew cartridge more after needing like this to shut down, and the time that this just need to be long, to dismantle and install cumbersome, this just exists certain inconvenience.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provides a kind of and need not repeatedly more renew cartridge and reusable accurate filter and reverse osmosis system take reverse osmosis concentrated water as wash-down water easy to use.
A kind of technical scheme that reusable accurate filter was adopted take reverse osmosis concentrated water as wash-down water of the present invention is: described accurate filter comprises the accurate filter I that is arranged in parallel, accurate filter II, the water-in I of described accurate filter I is connected with the first water inlet pipe and first row water pipe, the water outlet I of described accurate filter I is connected with the first rising pipe and the 3rd water inlet pipe, the water-in II of described accurate filter II is connected with the second water inlet pipe and second row water pipe, the water outlet II of described accurate filter II is connected with the second rising pipe and the 4th water inlet pipe, be connected with main water inlet tube after described the first water inlet pipe and described the second water inlet pipe parallel connection, be connected with delivery pipe after described first row water pipe and the parallel connection of described second row water pipe, be provided with pressure controlled valve on the described delivery pipe, be connected with primary flow pipe after described the first rising pipe and described the second rising pipe parallel connection, be connected described the first water inlet pipe with secondary water inlet pipe after described the 3rd water inlet pipe and described the 4th rising pipe parallel connection, described first row water pipe, described the first rising pipe, described the 3rd water inlet pipe, described the second water inlet pipe, described second row water pipe, be provided with described control valve on described the second rising pipe and described the 4th rising pipe.
Further, the withstand voltage automatically controlled valve of described control valve, described accurate filter are the pressure-resistant precision strainer, and what adopt in the described accurate filter is reusable pressure-resistant precision filter core.
The technical scheme that a kind of reverse osmosis system of the present invention adopts is: described reverse osmosis system comprises described accurate filter, working shaft, more medium filter, high-pressure pump, reverse osmosis unit, described working shaft is connected with described more medium filter, described more medium filter is connected with described main water inlet tube, described primary flow pipe is connected with described high-pressure pump, described high-pressure pump is connected with described reverse osmosis unit, and the water outlet of described reverse osmosis unit is connected with described secondary water inlet pipe.
Further, described reverse osmosis system also comprises energy recycle device, the water-in of described energy recycle device is connected with the water outlet of described reverse osmosis unit, the water outlet of described energy recycle device is connected with the water-in of described high-pressure pump by circulating line on the one hand, and another is conveniently discharged by water shoot.
The invention has the beneficial effects as follows: owing to the present invention includes the accurate filter I that is arranged in parallel, accurate filter II, the water-in I of described accurate filter I is connected with the first water inlet pipe and first row water pipe, the water outlet I of described accurate filter I is connected with the first rising pipe and the 3rd water inlet pipe, the water-in II of described accurate filter II is connected with the second water inlet pipe and second row water pipe, the water outlet II of described accurate filter II is connected with the second rising pipe and the 4th water inlet pipe, be connected with main water inlet tube after described the first water inlet pipe and described the second water inlet pipe parallel connection, be connected with delivery pipe after described first row water pipe and the parallel connection of described second row water pipe, be connected with primary flow pipe after described the first rising pipe and described the second rising pipe parallel connection, be connected with secondary water inlet pipe after described the 3rd water inlet pipe and described the 4th rising pipe parallel connection, described the first water inlet pipe, described first row water pipe, described the first rising pipe, described the 3rd water inlet pipe, described the second water inlet pipe, described second row water pipe, be provided with described control valve on described the second rising pipe and described the 4th rising pipe, when normal filtration, one of them filter core stops the particulate matter in the former water in filter core one side, allow and enter described reverse osmosis unit through the former water after filtering, the desalting treatment of pressurizeing, another filter is for subsequent use, when the filter core of work cuts dirty when saturated, conversion through described control valve, allow filter for subsequent use start working, and passed into described reverse osmosis unit strong brine out after the conversion of dirty stifled filter core process valve, because this strong brine is clean and with high pressure, these high-pressure thick water build the pressure under described control valve effect and reach setting pressure, with than the high a lot of pressure moment release of normal filtration, form larger pressure difference, comparatively thoroughly the stifled thing back flushing of the dirt in the filter core is gone out, thereby two filter cores are taken turns to operate, so the present invention need not more renew cartridge and easy to use.
