DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0023] Example 1:

[0024] This utility model provides a self-circulating ultrapure water equipment, please refer to Figure 1 , including a raw water tank 1, the raw water tank 1 is connected to a quartz sand filter 3 through a conduit, the quartz sand filter 3 uses quartz sand as a filter medium, and filters water with high turbidity through granular or non-granular quartz sand of a certain thickness, effectively intercepting and removing suspended matter, organic matter, colloid particles, microorganisms, chlorine, odor and some heavy metal ions in the water, and finally achieving the effect of reducing water turbidity and purifying water quality. The quartz sand filter 3 is connected to an activated carbon filter 4 through a conduit, and the activated carbon filter cylinder adopts a hydraulic simulation long-diameter design, and adopts high-efficiency activated carbon with a reasonable particle size and a specific surface area greater than 1000㎡ / g, so that it has both upper-layer special-effect filtration and lower-layer high-efficiency adsorption functions. The residual chlorine content of the water after treatment is excellent, and it has outstanding performance on odor, organic matter, colloid, iron and residual chlorine in the water body, and is effective in reducing the turbidity and color of the water body. Improve water quality and reduce pollution to subsequent systems (reverse osmosis, ultrafiltration, ion exchanger). The activated carbon filter 4 is connected to a precision filter 6 through a conduit. The precision filter 6 uses tubular filter elements such as PP melt-blown, wire-sintered, folded, titanium filter element, activated carbon filter element, etc. as filter elements to separate solids and liquids from various suspensions. The precision filter 6 is connected to a reverse osmosis device 8 through a conduit. The reverse osmosis device 8 is connected to a CO2 degassing tower 9 through a conduit. The CO2 degassing tower 9 uses the wind power of the fan to blow off free CO2 in the water. The CO2 degassing tower 9 is connected to an intermediate water tank 10 through a conduit. The intermediate water tank 10 is connected to an intermediate water pump 11 through a conduit. The intermediate water pump 11 is connected to an ion exchange mixed bed 14 and an EDI water tank 15 through a conduit. The ion exchange mixed bed 14 is used to further purify the water quality.

[0025] The ion exchange mixed bed 14 is connected to the terminal filter 12 via a conduit.

[0026] The system also includes a first booster pump 2, installed in the pipeline connecting the outlet of the raw water tank 1 and the inlet of the quartz sand filter 3. It also includes an antiscalant dosing device 5, installed in the pipeline connecting the outlet of the activated carbon filter 4 and the inlet of the precision filter 6. It also includes a second booster pump 7, installed in the pipeline connecting the outlet of the precision filter 6 and the inlet of the reverse osmosis device 8. It also includes a third booster pump 13, installed in the pipeline connecting the output end of the intermediate water pump 11 and the inlet of the ion exchange mixed bed 14.

[0027] During actual use, the water in the raw water tank 1 is pumped into the quartz sand filter 3 by the first booster pump 2 for filtration. The quartz sand filter 3 uses quartz sand as a filter medium to filter the water with high turbidity through a certain thickness of granular or non-granular quartz sand, effectively intercepting and removing suspended matter, organic matter, colloidal particles, microorganisms, chlorine, odor and some heavy metal ions in the water, ultimately achieving the effect of reducing water turbidity and purifying water quality.

[0028] After that, the water enters the activated carbon filter 4. The activated carbon filter cylinder adopts a hydraulic simulation long-diameter design and uses high-efficiency activated carbon with reasonable particle size and specific surface area greater than 1000 m2 / g, so that it has both upper-layer special-effect filtration and lower-layer high-efficiency adsorption functions. The residual chlorine content in the treated water is excellent, and it has excellent performance on odor, organic matter, colloid, iron and residual chlorine in the water body. It can reduce the turbidity and color of the water body, purify the water quality, and reduce the pollution to the subsequent systems (reverse osmosis, ultrafiltration, ion exchanger).

[0029] After that, the water enters the precision filter 6 for filtration. The precision filter 6 uses tubular filter elements such as PP melt-blown, wire-sintered, folded, titanium filter element, activated carbon filter element, etc. as filter elements to separate the solid and liquid of various suspensions.

[0030] The water is then pumped into the reverse osmosis equipment 8 by the second booster pump 7 for treatment, and then passes through the CO2 degassing tower 9 to remove free CO2 from the water; the pure water can then enter the EDI water tank 15 for storage, or enter the ion exchange mixed bed 14 for further water purification.

[0032] Refer to the attached Figure 2 , which is different from Example 1 in that it further includes an air filter 16, a pre-treatment filter element 17 and a fourth booster pump 18;

[0033] The water outlet of the air filter 16 is connected to the water inlet of the raw water tank 1 through a conduit, the pretreatment filter element 17 and the air filter 16 are connected through a conduit, and the water inlet of the pretreatment filter element 17 is connected to the fourth booster pump 18 through a conduit; the air filter 16 captures dust from the gas-solid two-phase flow through the action of the porous filter material and purifies the gas; at this time, the air filter 16 and the pretreatment filter element 17 first treat the water.

[0034] Example 3:

[0035] Refer to the attached Figure 3 , which is different from Example 1: it also includes a polishing resin filter element 19, which is arranged between the activated carbon filter 4 and the scale inhibitor dosing device 5; after being filtered by the quartz sand filter 3 and the activated carbon filter 4, the water enters the polishing resin filter element 1 for filtration, and then is filtered in the precision filter 6.
