Description

Technical Field

[0001] The invention relates to the technical field of reverse osmosis systems, and in particular to a device for improving water production rate of a reverse osmosis system. Background Art

[0002] According to general industry data and actual operating experience, the water production rate of the reverse osmosis system is generally between 50% and 75%, which means that when processing a certain amount of raw water, approximately 50% to 75% of the water can pass through the reverse osmosis membrane to become pure water. If 1 ton of pure water is produced, 1.4 to 3 tons of raw water may be consumed. However, this range is not absolute, because the actual water production rate and water consumption will be affected by many factors.

[0003] In the prior art, the newly added ultraviolet mobile skid device can destroy and change the DNA or RNA molecular structure of microorganisms through ultraviolet irradiation, causing growth cell death and regenerative cell death to achieve the purpose of sterilization, thereby improving the purity of water purification at the first-level water outlet of the reverse osmosis device, and delivering it to the inlet of the secondary reverse osmosis device through the booster pump group, which not only provides a stable water supply pressure for the secondary reverse osmosis device, but also can sterilize according to ultraviolet rays with a wavelength of 254nm, thereby increasing the water production rate and reducing the water consumption required for producing 1 ton of pure water. However, it usually takes a certain amount of time to achieve the ideal sterilization effect when ultraviolet rays sterilize water. At present, when sterilizing water, the water flow passes through the pressurized flow rate at a faster rate, so that when it is sterilized by ultraviolet rays, the sterilization effect is limited due to the short irradiation time, resulting in the subsequent secondary reverse osmosis equipment taking more time to purify the water, further reducing the service life of the secondary reverse osmosis equipment.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0018] Example like Figures 1 to 9 As shown, a device for improving water production rate of a reverse osmosis system comprises: a base plate 1 placed on the ground, a support frame 2 is fixedly installed at the rear end of the top of the base plate 1, a first ultraviolet sterilization tube 3 and a second ultraviolet sterilization tube 4 are fixedly installed at the left and right ends of the top of the support frame 2 respectively, a water inlet pipe 5 is fixedly installed on the outer side of the right end of the second ultraviolet sterilization tube 4, a first ball valve 6 is fixedly installed below the first ultraviolet sterilization tube 3, a filter 7 is fixedly installed at the bottom end of the first ball valve 6, a booster pump 8 is fixedly installed at the left end of the top of the base plate 1 and on the right side of the filter 7, a check valve 9 is fixedly installed at the right end of the booster pump 8, a second ball valve 10 is fixedly installed at the front end of the check valve 9, a needle valve 11 is fixedly installed at the front end of the second ball valve 10, and a water outlet pipe 12 is fixedly installed at the front end of the needle valve 11.

[0019] The raw water passes through a series of pre-filtrations and enters the primary reverse osmosis device, and then enters the first ultraviolet sterilization cylinder 3 and the second ultraviolet sterilization cylinder 4 through the water inlet pipe 5. Through the irradiation of ultraviolet rays, the DNA or RNA molecular structure of the microorganisms is destroyed and changed, causing the death of growth cells and regenerative cells to achieve the purpose of sterilization. Subsequently, it passes through the filter 7 for secondary filtration, which improves the purity of the purified water discharged from the final outlet pipe 12. The outlet pipe 12 is connected to the inlet of the secondary reverse osmosis device and is transported to the inlet of the secondary reverse osmosis device through the booster pump 8, which not only provides a stable water supply pressure to the secondary reverse osmosis device, but also can sterilize according to ultraviolet rays with a wavelength of 254nm, thereby improving the water production rate and reducing the water consumption required for producing 1 ton of pure water.

[0020] In this embodiment, the specific structures inside the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4 are as follows: A protective cover 401 is fixedly installed on the opposite end of the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4, a lamp holder 402 is movably installed on the opposite end of the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4 and located on the inner side of the protective cover 401, a plurality of groups of ultraviolet lamp tubes 403 are fixedly installed inside the lamp holder 402, a stabilizing frame 404 is fixedly installed on the left and right ends inside the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4 and located on the outer side of the ultraviolet lamp tube 403, a plurality of groups of mounting sleeves 405 are fixedly installed on the outer side of the ultraviolet lamp tube 403 and located between the two groups of stabilizing frames 404, and a plurality of groups of baffles 406 are fixedly connected to the upper and lower sides of the plurality of mounting sleeves 405.

[0021] The ultraviolet lamp tube 403 is equipped with a quartz sleeve with high penetration and a corresponding electrical controller. After the raw water is introduced into the second ultraviolet sterilization tube 4 through the water inlet pipe 5, the flow rate of the water flow is reduced by multiple groups of baffles 406, so that the water flow is fully irradiated by the ultraviolet lamp tube 403, thereby ensuring the effect of ultraviolet sterilization, and then introduced into the interior of the first ultraviolet sterilization tube 3 for secondary sterilization, thereby greatly improving the effect of ultraviolet sterilization to increase the water production rate. At the same time, there is no need for the secondary reverse osmosis equipment to spend more time to purify the water, which further improves the service life of the secondary reverse osmosis equipment.

[0022] A wiring tube 407 is fixedly connected to the outside of the protective cover 401, and a sealing sleeve 408 is fixedly provided on the outside of the lamp holder 402, and the outside of the sealing sleeve 408 is snap-fitted with the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4. The lamp holder 402 is installed and positioned by the sealing sleeve 408, while ensuring the sealing of the connection with the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4 after installation. Subsequently, the protective cover 401 is installed and fixed on the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4 to protect the outside of the lamp holder 402, and the ultraviolet lamp tube 403 is connected and conductive through the wiring tube 407.

[0023] The stabilizing frame 404 is composed of a first half frame 409 and a second half frame 410. The first half frame 409 and the second half frame 410 are respectively sleeved on the upper and lower sides of the left and right ends of the plurality of groups of ultraviolet lamp tubes 403. The first half frame 409 and the second half frame 410 are fixedly connected by a first fixing screw 411. The inner sides of the first half frame 409 and the second half frame 410 and the outer sides of the ultraviolet lamp tubes 403 are fixedly connected with rubber positioning sleeves 412. The left and right ends of the first half frame 409 and the second half frame 410 are rotatably connected with rollers 413, and the plurality of groups of rollers 413 are all in contact with the inner side walls of the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4. When the ultraviolet lamp tubes 403 are installed When installing into the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4, firstly, the first half frame 409 and the second half frame 410 are respectively sleeved on the upper and lower sides of the left and right ends of the multiple groups of ultraviolet lamp tubes 403, and then the first half frame 409 and the second half frame 410 are fixed by the first fixing screw 411. Then, with the assistance of the roller 413, the ultraviolet lamp tube 403 is conveniently and stably inserted into the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4 for auxiliary installation, which not only improves the installation convenience of the ultraviolet lamp tube 403, but also uses the rubber positioning sleeve 412 to position and protect the ultraviolet lamp tube 403, and ensures the stability of the ultraviolet lamp tube 403 after installation.

[0024] The installation sleeve 405 is composed of a first half sleeve 414 and a second half sleeve 415. The first half sleeve 414 and the second half sleeve 415 are respectively sleeved on the upper and lower sides of the middle of the multiple groups of ultraviolet lamp tubes 403. The first half sleeve 414 and the second half sleeve 415 are fixedly connected by multiple groups of second fixing screws 416. The inner sides of the first half sleeve 414 and the second half sleeve 415 and the outside of the ultraviolet lamp tube 403 are fixedly connected with a rubber protective sleeve 417, so that the stabilizing frame 404 is installed and fixed on the outside of the ultraviolet lamp tube 403. When installing the stabilizing frame 404 at the right end on the outside of the ultraviolet lamp tube 403, first install the installation sleeve 405, and install the installation sleeve 405 on the outside of the ultraviolet lamp tube 403 layer by layer by sliding from left to right, then tighten the second fixing screw 416 to lock it, and protect the outside of the ultraviolet lamp tube 403 with the rubber protective sleeve 417. After all the installation sleeves 405 are installed and fixed, the stabilizing frame 404 at the left end is installed and fixed on the outside of the ultraviolet lamp tube 403.

[0025] A plurality of groups of baffles 406 are staggeredly distributed on the outside of the first half sleeve 414 and the second half sleeve 415, respectively. A plurality of groups of light-transmitting holes 418 are provided at positions on the outside of the first half sleeve 414 and the second half sleeve 415 corresponding to the ultraviolet lamp tube 403. The surfaces of the first half sleeve 414, the second half sleeve 415 and the baffles 406 are coated with a reflective coating. When the ultraviolet lamp tube 403 is located inside the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4, the ultraviolet rays emitted by the ultraviolet lamp tube 403 irradiate the water flow through the plurality of groups of light-transmitting holes 418, and the ultraviolet rays are reflected by the reflective coating so as to fully irradiate the water flow. At the same time, when the water flow flows in the plurality of groups of staggered baffles 406, the flow rate of the water flow can be reduced so that the water flow can fully stay inside the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4, thereby allowing the ultraviolet rays to fully irradiate and sterilize the water flow.

[0026] The first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4 are fixedly connected via a connecting tube 301. The front and rear ends of the bottoms of the first ultraviolet sterilization tube 3 and the second ultraviolet sterilization tube 4 are fixedly connected to the support frame 2 via a mounting seat 302. A sampling tube 303 is fixedly installed on the outer side of the left end of the second ultraviolet sterilization tube 4. After water flows into the interior of the first ultraviolet sterilization tube 3 for irradiation and sterilization, it is introduced into the interior of the second ultraviolet sterilization tube 4 through the connecting tube 301 for a second irradiation and sterilization, thereby greatly improving the ultraviolet sterilization effect to increase the water production rate. Water samples can be taken out through the sampling tube 303 to detect the sterilization effect.

[0027] The filter 7 consists of a connector 701 and a quick-release sleeve 702. The connector 701 is fixedly installed at the bottom end of the first ball valve 6. The quick-release sleeve 702 is threadedly connected to the outer side of the connector 701. A filter element 703 is fixedly installed inside the quick-release sleeve 702. A positioning mechanism 704 is installed inside the quick-release sleeve 702 and at the left end of the filter element 703. A slow-flow sleeve 705 is fixedly installed inside the quick-release sleeve 702 and at the outer side of the filter element 703. A waste discharge head 706 is threadedly connected to the outer side of the quick-release sleeve 702. A waste discharge groove 707 is provided at a position corresponding to the waste discharge head 706 inside the quick-release sleeve 702. After being sterilized by ultraviolet irradiation, the raw water is introduced into the interior of the quick-release sleeve 702 through the connector 701, and the raw water is filtered again through the filter element 703 for a second time, thereby improving the purity of subsequent discharged water purification. The waste discharge head 706 can be unscrewed to clean the filtered impurities.

[0028] The positioning mechanism 704 includes a spring 708 fixedly connected to the inside of the quick-release sleeve 702, and a positioning block 709 is fixedly connected to one end of the spring 708 close to the filter element 703. A first sealing ring 710 is sleeved between the positioning block 709 and the filter element 703. After the quick-release sleeve 702 is installed on the outside of the connecting head 701, the positioning block 709 is pushed by the action of the spring 708, so that the filter element 703 is firmly installed in the inside of the quick-release sleeve 702. At the same time, the sealing is guaranteed by the first sealing ring 710, and the subsequent unscrewing of the quick-release sleeve 702 also facilitates the quick release of the fixation of the filter element 703, and facilitates the disassembly and maintenance of the filter element 703.

[0029] The upper and lower ends of the filter element 703 are both sleeved with a second sealing ring 711, and the interior of the slow flow sleeve 705 is provided with a spiral slow flow channel 712. The spiral slow flow channel 712 is located on the side of the slow flow sleeve 705 close to the filter element 703 and has multiple sets of drainage holes 713. The second sealing ring 711 can ensure the sealing of the upper and lower ends of the filter element 703 after installation. After the raw water enters the interior of the quick release sleeve 702, it is introduced into the spiral slow flow channel 712 in the slow flow sleeve 705, so as to reduce the flow rate of the water so that it can fully stay in the quick release sleeve 702. When the raw water flows, it is discharged from the filter element 703 through the drainage holes 713 for filtration, thereby greatly improving the filtering effect of the raw water, and then improving the purity of the subsequent discharged water purification.

[0030] An electric control box 201 is fixedly installed on the front of the support frame 2, and the booster pump 8 is fixedly connected to the filter 7 through a connecting pipe 801. The bottom of the booster pump 8 and the needle valve 11 are fixedly connected to the bottom plate 1 through a mounting frame 802. A pressure gauge 1101 is installed on the needle valve 11. The start and stop of the entire device is controlled by the electric control box 201. After sterilization and filtration, the raw water is introduced into the booster pump 8 through the connecting pipe 801 and transported to the inlet of the secondary reverse osmosis equipment through the booster pump 8, which not only provides a stable water supply pressure to the secondary reverse osmosis equipment, but also can effectively increase the water output. The water supply pressure can be observed through the pressure gauge 1101.

[0031] Implementation scheme: The raw water is filtered through a series of pre-filters and enters the primary reverse osmosis equipment, and then enters the first ultraviolet sterilization cylinder 3 and the second ultraviolet sterilization cylinder 4 through the water inlet pipe 5. The flow rate of the water flow is reduced by multiple groups of baffles 406, so that the water flow is fully irradiated by the ultraviolet lamp 403, thereby ensuring the effect of ultraviolet sterilization. Subsequently, the water is introduced into the first ultraviolet sterilization cylinder 3 for secondary sterilization, thereby greatly improving the effect of ultraviolet sterilization to increase the water production rate. At the same time, the subsequent secondary reverse osmosis equipment does not need to spend more time to purify the water, which further improves the service life of the secondary reverse osmosis equipment. Through ultraviolet irradiation, the DNA or RNA molecular structure of microorganisms is destroyed and changed, causing the death of growth cells and regenerative cells to achieve the purpose of sterilization. Subsequently, the water is filtered for the second time through the filter 7 to improve the purity of the purified water discharged from the final outlet pipe 12. The outlet pipe 12 is connected to the inlet of the secondary reverse osmosis equipment and is transported to the inlet of the secondary reverse osmosis equipment through the booster pump 8. It not only provides a stable water supply pressure to the secondary reverse osmosis equipment, but also can sterilize according to ultraviolet rays with a wavelength of 254nm, thereby improving the water production rate and reducing the water consumption required for producing 1 ton of pure water.
