Description

The development of core treatment technology alone is not enough to meet the current wide range of requirements in the application field of pure water, especially ultrapure water. The process mainly consists of three parts: pretreatment + core treatment + auxiliary treatment. With the continuous development of current water treatment technology, the following phenomena are occurring: Pretreatment: New pretreatment processes represented by ultrafiltration / microfiltration are competing and cooperating with traditional sand filtration and carbon filtration; Core treatment: With the widespread application of EDI technology and equipment, the application scope of traditional ion exchange cation and cation bed processes is becoming less and less; The application of softening resin and polishing resin processes remains strong, and the development of special resins is becoming more and more diverse; Auxiliary treatment: With the semiconductor industry's increasingly stringent requirements on ultrapure water quality, technologies such as degassing membrane systems and terminal ultrafiltration are developing rapidly.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The present invention provides Figure 1A pure water preparation device shown includes a raw water storage tank 1, a softening filter 2, a water diversion pump 3, a reverse osmosis mechanism 4, a deionization filter tank 5 and a pure water storage tank 6, and the various components are connected by a water supply pipe 7, and each section of the pipe is provided with a valve for water flow control. The raw water storage tank 1 stores raw water for preparing pure water, and the pure water storage tank 6 stores the final pure water.

[0043] Specifically, Figure 3 As shown, the softening filter 2 includes an outer tank body 21, and an upper top cover 22 and a lower bottom cover 23 are respectively provided at both ends of the outer tank body 21. The upper top cover 22 and the lower bottom cover 23 are connected to the outer tank body 21 by fixing bolts, and the connection is also provided with a sealing strip. An anti-reverse resistance filter element mechanism 24 is provided inside the outer tank body 21, and a water collecting bucket 25 is provided at the bottom of the anti-reverse resistance filter element mechanism 24. Through the operation of the water diversion pump 3 and the diversion of the water supply pipeline 7, the raw water in the raw water storage tank 1 is transported from the upper top cover 22 to the inner cavity of the outer tank body 21, and the granular impurities in the raw water are removed through the pretreatment of the anti-reverse resistance filter element mechanism 24. When the softening filter 2 is set, the number thereof can be set to multiple groups, and the filter core materials in the multiple groups of softening filters 2 are respectively selected from quartz sand filter materials, activated carbon filter materials or iron and manganese removal filter materials, so as to achieve the pretreatment effect of the raw water.

[0044] like Figure 3-7 As shown, the upper top cover 22 and the lower bottom cover 23 both include a supporting circular plate 221, and fixing holes 222 are provided in a circular array at the connection between the supporting circular plate 221 and the fixing bolts; a through hole is provided at the center of the supporting circular plate 221 corresponding to the lower bottom cover 23 and at the position corresponding to the water supply pipe 7; a water inlet pipe 223 is provided at the center of the supporting circular plate 221 corresponding to the upper top cover 22 and at the position corresponding to the water supply pipe 7, an electronic flow meter I 224 is connected to one side of the water inlet pipe 223, and a transmission motor 225 is also provided at one side of the water inlet pipe 223.

[0045] The anti-reverse resistance filter element mechanism 24 includes an upper loading plate 241 and a lower loading plate 242, and a plurality of filter columns 244 are evenly arranged between the upper loading plate 241 and the lower loading plate 242. A plurality of fixed screws 243 are evenly arranged in a circular array at the edges of the upper loading plate 241 and the lower loading plate 242. A rod-shaped lifting paddle 245 is provided inside each filter column 244, and a transmission gear 246 is fixed on the top of the rod-shaped lifting paddle 245, and adjacent transmission gears 246 are meshed for transmission.

[0046] The upper loading plate 241 and the lower loading plate 242 both include a bearing plate 2411 . The bearing plate 2411 and both ends of the filter column 244 are connected with locking grooves 2412 . The edge of the bearing plate 2411 and the fixing screw 243 are connected with locking holes 2413 .

[0047] Handle handles 2414 are fixedly provided on both sides of the top surface of the carrying plate 2411 corresponding to the upper carrying plate 241 .

[0048] The raw water in the raw water storage tank 1 is guided by the water diversion pump 3 and the water delivery pipe 7, and enters the inner cavity of the outer tank body 21 through the water inlet pipe 223. During this period, the water flow passing through the water inlet pipe 223 is measured by the electronic flow meter I 224, and then enters the filter column 244 from the position of the fixing groove 2412 corresponding to the upper loading plate 241 for pre-treatment filtration, so that the suspended debris solids in the raw water are discharged from the anti-reverse filter element mechanism 24 through the fixing groove 2412 corresponding to the downloading plate 242, thereby completing the initial filtration of the pre-treatment of the raw water.

[0049] like Figure 3 and 8 As shown, the water collecting bucket 25 includes a curved bucket 251, a conductive tube 252 is fixedly provided at the bottom end of the curved bucket 251, and the conductive tube 252 is externally connected to an electronic flow meter II 253, and the display meter of the electronic flow meter II 253 is arranged at the outer wall of the outer tank body 21; the bottom end of the conductive tube 252 is connected to the water supply pipe 7, and the outer diameter of the top of the curved bucket 251 and the outer diameter of the download plate 242 are equal to the inner diameter of the outer tank body 21, and the curved bucket 251 and the download plate 242 are fixedly connected to the inner wall of the outer tank body 21, the outer diameter of the upper loading plate 241 is equal to the inner diameter of the outer tank body 21, and the upper loading plate 241 is movably connected to the outer tank body 21.

[0050] The filtered water discharged from the anti-reverse resistance filter element mechanism 24 is collected by the arc-surface bucket 251, and then transported to the reverse osmosis mechanism 4 or another softening filter 2 through the conduction pipe 252 via the water supply pipeline 7. During this period, the water flow rate flowing through the conduction pipe 252 is measured by the electronic flow meter II 253.

[0051] like Figure 2 As shown, the reverse osmosis mechanism 4 includes a mounting frame 41 , on which a control box 44 and a plurality of reverse osmosis membrane filter components 45 are also provided.

[0052] The control box 44 sets the detection flow ratio value of the electronic flow meter I 224 and the electronic flow meter II 253. Since there will be a proportional difference in the water flow filtered by the anti-reverse resistance filter element mechanism 24, the measurement value of the electronic flow meter II 253 is set to 20%-30% of the measurement value of the electronic flow meter I 224. If it is lower than the ratio value, the control box 44 controls the transmission motor 225 to work, thereby driving the anti-reverse resistance filter element mechanism 24 to perform the reverse membrane layer barrier generation work, thereby ensuring the smooth filtering work of the anti-reverse resistance filter element mechanism 24.

[0053] like Figure 9-10As shown, the filter column 244 includes a bearing column shell 2441, and an upper connecting convex cover 2442 and a lower connecting convex cover 2443 are respectively provided at both ends of the bearing column shell 2441. A mounting through hole is opened at the center of the upper connecting convex cover 2442 and the connection place where it is connected to the rod-shaped lifting paddle 245, and a plurality of water seepage holes are evenly arranged on the upper connecting convex cover 2442; a water through hole is also opened on the lower connecting convex cover 2443, and the filter column 244 is respectively fixed by the upper connecting convex cover 2442 and the lower connecting convex cover 2443 with the fixing grooves 2412 corresponding to the upper loading plate 241 and the downloading plate 242, so that the water entering the outer tank body 21 enters the bearing column shell 2441 through the water seepage hole, and is discharged from the water through hole after being filtered by the filter core material, thereby completing the pre-treatment filtration.

[0054] A filter core material is also provided in the inner cavity of the bearing column shell 2441. The filter core material is made of quartz sand filter material, activated carbon filter material or iron and manganese removal filter material. The filter core material is in crushed granular form to ensure that the water flow entering the bearing column shell 2441 is in full contact with the filter core material.

[0055] like Fig.10 As shown, the rod-shaped lifting paddle 245 includes a conductive rod 2451, and a lifting paddle 2452 is provided on the outer wall of the conductive rod 2451. The conductive rod 2451 and the lifting paddle 2452 are integrally formed, and the lifting paddle 2452 is arranged in a sheet-like spiral shape, so that when the rod-shaped lifting paddle 245 is rotated, the lifting paddle 2452 drives the granular filter core material to loosen and lift, and a disc-shaped chassis is fixed at the bottom end of the lifting paddle 2452.

[0056] The water diversion pump 3, the booster pump 42, the electronic flow meter I 224, the transmission motor 225 and the electronic flow meter II 253 are all electrically connected to the control box 44. When the control box 44 detects that the detection values ​​of the two flow meters corresponding to the softening filter 2 during operation are lower than the proportional value, the control box 44 controls the transmission motor 225 to work. Since the output shaft of the transmission motor 225 is connected to the top of a rod-shaped lifting paddle 245, and the transmission gears 246 are meshed and driven, the rod-shaped lifting paddles 245 work synchronously. During this period, the sheet-shaped spiral lifting paddle 2452 rotates continuously, so that the granular filter core material at this height is loosened and disturbed, thereby avoiding the formation of a blocking film / layer in the filter core material due to the blocking residue during operation, and the lifting The disc-shaped chassis at the bottom of the lifting paddle 2452 follows the rotation of the conduction rod 2451 to limit the height and level the lifted loose material, effectively avoiding the failure of the filtration work due to the synchronous loosening of the granular filter core material (due to the loosening of the core material, the gap between the granular materials increases and the filtering effect is lost). Under the premise of ensuring the filtering effect, the film layer generation state inside the core material is released, that is, the granular material changes its position due to disturbance, thereby driving the accumulation of impurities at the core material at this position to form a film layer (reverse membrane layer barrier generation work), ensuring the smooth filtration work of the anti-reverse resistance filter element mechanism 24, so as to ensure the processing efficiency of the pretreatment work.

[0057] like Figure 2 As shown, a booster pump 42 and a precision filter 43 are also installed on the mounting frame 41, wherein the booster pump 42, the precision filter 43 and the reverse osmosis membrane filter component 45 are arranged along the conveying direction of the water supply pipe 7, and the pre-treated water in the softening filter 2 is pumped to the precision filter 43 by the booster pump 42, and the solid particles and bacteria in the liquid are retained on the surface of the filter bag by utilizing the microporous structure of the filter bag, thereby achieving liquid purification, and the water flow after precision filtration enters the reverse osmosis membrane filter component 45, and small molecular weight particles, bacteria and organic matter in the water flow are removed, thereby obtaining pure water, which is transported to the deionization filter tank 5 by the water supply pipe 7, and high-purity deionized pure water is obtained by utilizing ion exchange or reverse osmosis technology, and is concentrated and stored in the pure water storage tank 6.

[0058] like Figure 11-15 The reverse osmosis membrane filter component 45 includes a main pipe shell 451, both ends of the main pipe shell 451 are fixed with connecting columns 452, the connecting columns 452 include a water inlet column and a water outlet column, a central pipe 453 is provided inside the main pipe shell 451, a reverse osmosis membrane filter element 454 is provided outside the central pipe 453, and water permeable holes are evenly opened on the central pipe 453. The reverse osmosis membrane filter element 454 is configured as a permeate collection network, an RO membrane and a flow channel network are stacked and wound outside the central pipe 453, wherein the RO membrane is configured as a hole The RO membrane has a diameter of 1 / 10000 μm; a water storage cavity is provided inside the water inlet column and the water outlet column, and a connecting pipe 456 connected to the water storage cavity is provided at the port position of the water inlet column and the water outlet column, and a speed resistance component 455 is also provided in the water storage cavity corresponding to the water inlet column, and the two ends of the speed resistance component 455 are respectively connected to the connecting pipe 456 corresponding to the water inlet column and the central pipe 453, and a guide pipe 457 is provided between adjacent speed resistance components 455 and between the speed resistance component 455 and the central pipe 453.

[0059] The speed-blocking assembly 455 includes a water-blocking cylinder 4551, which has a water inlet 4552 and a water outlet 4553 at both ends. A partition plate 4554 is fixedly provided in the inner cavity of the water-blocking cylinder 4551, and the inner cavity of the water-blocking cylinder 4551 is divided into a liquid collecting chamber I 4555 and a liquid collecting chamber II 4556 by the partition plate 4554.

[0060] The partition plate 4554 is composed of a V-shaped ring plate at the edge and a partition plate at the center. Impact hole I 4557 and impact hole II 4558 are respectively opened on the two side walls of the V-shaped ring plate.

[0061] The specific implementation method is as follows: water flows through the water delivery pipe 7, enters the speed-resistance component 455 through the connecting pipe 456 corresponding to the water inlet column, enters the liquid collecting chamber I 4555 through the water inlet 4552, and enters the large-diameter liquid collecting chamber I 4555 through the small-diameter connecting pipe 456 to reduce the water flow speed. The gathered water flows are respectively sent to the liquid collecting chamber II through the impact hole I 4557 and the impact hole II 4558. 4556, the impact of water flow in different directions forms a disturbance, reducing the water flow value, and then enters the central tube 453 through the outlet 4553, and is sent to the reverse osmosis membrane filter element 454 through the water permeable holes on the central tube 453, so that a large number of impurities such as bacteria and viruses in the water flow are completely isolated, and then discharged from the reverse osmosis membrane filter component 45 through the water outlet column, and pure water that meets the requirements of fertilizer production is produced, reducing the damage of the reverse osmosis membrane filter element 454 caused by excessive water pressure or insufficient quality of generated pure water caused by excessive water flow when the high-pressure water flow generated by the heating of the high-pressure water pump in the prior art enters the reverse osmosis device, and effectively avoiding the quality of the centralized pure water storage tank 6 from being affected, so as to ensure that the discharged pure water meets the standards.
