Description

Technical Field

[0001] The utility model relates to the technical field of seawater desalination, in particular to a multi-stage seawater desalination circulation device. Background Art

[0002] Seawater desalination is an important way to solve the problem of freshwater shortage, especially for arid areas or island countries. Traditional seawater desalination methods mainly include distillation and reverse osmosis. Although these methods can achieve seawater desalination to a certain extent, there are problems such as high energy consumption, large equipment size, and high operating costs.

[0003] Disadvantages of existing seawater desalination devices:

[0004] High energy consumption: Traditional desalination devices usually require a lot of energy to operate. In particular, the distillation method requires a lot of fuel or electricity to generate steam, and the reverse osmosis method also requires a high-pressure pump to push water through the semi-permeable membrane, which leads to high energy consumption and high costs.

[0005] High maintenance costs: Traditional devices have high maintenance and operating costs. Due to the complex structure of the equipment, the cost and time of repair and replacement of parts are high, especially when downtime for maintenance is required, which will cause inconvenience and interruption to water supply.

[0006] Inflexible operation: Traditional desalination plants are usually single-channel, single-process structures. Once one of the channels fails or requires maintenance, the entire plant will stop operating, lacking flexibility and reliability.

[0007] Therefore, this invention proposes a multi-stage seawater desalination circulation device to solve the above problems. Utility Model Content

[0008] In order to overcome the defects of the prior art, the utility model aims to provide a multi-stage seawater desalination circulation device.

A chamber connected to one end of the inner side of the 6 liquid inlet channels is arranged at the center of the interior of the desalination machine base, and a central conversion liquid guide chassis is rotatably installed inside the chamber. The central conversion liquid guide chassis is cylindrical and has a liquid inlet connected to one end of the inner side of the liquid inlet channel on the side. A transposition mechanism that can drive the central conversion liquid guide chassis to rotate to a specific angle is installed at the top center of the desalination machine base.

[0014] A reverse osmosis membrane distributed inside each of the fixing frames;

[0015] A connecting column is provided between each of the fixing frames and the filter grid plate.

[0016] Preferably, a permeation component export mechanism that can drive the multi-stage permeation component to be exported from the desalination machine base is provided at the bottom of each liquid inlet channel. The permeation component export mechanism is specifically installed in an installation groove at the bottom of each liquid inlet channel and distributed along the channel direction.

[0026] Preferably, a channel end hatch is installed at one end of the outer side of each of the liquid inlet channels, and a liquid inlet pipe is installed at the center of the channel end hatch.

[0027] The beneficial effects of the utility model are embodied in:

[0028] Continuous operation: The six radial inlet channels and their matching permeation components in the equipment can achieve continuous and uninterrupted seawater desalination operation. Through the transposition function of the central conversion liquid guide chassis, it is easy to switch to the next inlet channel, while the permeation component in the previous channel is repaired or replaced, ensuring the continuous operation of the equipment.

[0029] Efficient cleaning: The design of the desalination base allows the desalination structure in multiple liquid inlet channels to be cleaned or replaced without affecting the operation of other channels. This structure makes the maintenance of the equipment more efficient, reducing downtime and maintenance costs.

[0051] Please refer to the instruction manual Figure 1-Figure 7 The utility model provides a multi-stage seawater desalination circulation device:

[0052] Overall structure of the equipment

[0053] Desalination machine base structure:

[0054] The desalination machine base 1 is designed as a disc-shaped structure, which provides structural integrity and convenience of operation.

[0055] A chamber is arranged at the center of the desalination machine base 1, which is connected to six radially distributed liquid inlet channels 2. This design allows the desalination structures in other liquid inlet channels 2 to be cleaned or replaced while one of the liquid inlet channels 2 is being desalinated, which is more efficient.

[0056] The central conversion liquid guiding box is located in the central chamber of the desalination base 1 and is cylindrical.

[0057] A liquid inlet 61 is provided on the side surface and communicated with one end of the inner side of the liquid inlet channel 2 .

[0058] The transposition mechanism 7 can be driven to achieve a specific angle of rotation so as to align with different liquid inlet channels 2 to perform seawater desalination operations.

[0059] Transposition mechanism:

[0060] It includes a driving shaft 71 , a transmission gear 72 , a driving gear 73 and a reduction motor 74 .

[0061] The driving gear 73 is controlled to rotate by the reduction motor 74, thereby driving the transmission gear 72 and the driving shaft 71 to rotate to a specific angle, and then accurately adjusting the rotation angle of the center conversion liquid guide chassis 6 to rotate and align it with the inner end of the next liquid inlet channel 2. At this time, the liquid inlet pipe 3 at the outer end of this liquid inlet channel 2 can be connected, and the seawater desalination operation can be performed through the multi-stage osmosis component 5 inside the liquid inlet channel 2. At this time, the multi-stage osmosis component 5 inside the previous liquid inlet channel 2 can be cleaned, repaired or replaced.

[0062] Multi-stage penetration kit

[0063] Structure composition:

[0064] The filter grid plate 51 is located at one end of each liquid inlet channel 2 close to the outer side.

[0065] A plurality of fixing frames 52 are equidistantly distributed on the inner side of the filter grid plate 51 .

[0066] A reverse osmosis membrane 53 is installed in each fixing frame 52 .

[0067] The connecting column 54 connects the fixing frame 52 and the filter grid plate 51 .

[0068] Function and effect:

[0069] The filter grid 51 first filters larger particles and impurities in the seawater.

[0070] The reverse osmosis membrane 53 is used for further filtration and desalination and is a core desalination component. By selecting multiple reverse osmosis membranes, multi-stage osmosis can be achieved to ensure the quality of seawater desalination.

[0071] Component construction of the penetration component export mechanism:

[0072] The driving motor 41 is installed at one end inside the bottom mounting groove 12 of each liquid inlet channel 2 .

[0073] The driving screw rod 42 is connected to the output end of the driving motor 41 .

[0074] The screw sleeve 43 is threadedly sleeved on the driving screw 42 and fixedly connected to the bottom center of one inner end of the multi-stage permeation component 5 inside the liquid inlet channel 2.

[0075] Functions and effects of the penetration component export mechanism:

[0076] By driving the motor 41 to rotate, the screw rod 42 and the screw rod sleeve 43 work together to push the multi-stage permeation component 5 to move along the liquid inlet channel 2. At this time, the channel end hatch 11 at the outer end of the liquid inlet channel 2 is opened to allow it to be guided out, and then the multi-stage permeation component 5 inside the liquid inlet channel 2 can be cleaned, inspected or replaced.

[0077] Other structural components

[0078] Desalinated liquid outlet pipe 31: It is installed at the bottom center of the desalination machine base 1 and is connected to the inside of the central conversion liquid guide box 6 for exporting the treated desalinated water.

[0079] Liquid inlet pipe 3 and channel end hatch 11:

[0080] A channel end hatch 11 is installed at one end of the outer side of each liquid inlet channel 2, and a liquid inlet pipe 3 is installed in the center for introducing seawater into the liquid inlet channel.

[0081] How it works

[0082] Equipment operation process

[0083] Startup and water filling:

[0084] After the device is started, seawater is introduced into the interior of the liquid inlet channel 2 through the liquid inlet pipe 3 at the front end of one of the liquid inlet channels 2 .

[0085] Desalination process:

[0086] The seawater is first filtered through the filter grid 51 inside the liquid inlet channel 2 to remove large particles of impurities.

[0087] The water molecules pass through the reverse osmosis membranes 53 in the plurality of fixed frames 52 , and the salt is intercepted by the membranes. The water molecules are introduced into the interior of the central conversion liquid guide box 6 through the liquid inlet 61 , and are discharged at the desalinated liquid outlet pipe 31 .

[0088] Adjustment and optimization:

[0089] When the multi-stage permeation assembly 5 inside the liquid inlet channel 2 has been working for a long time, the central conversion liquid guide chassis 6 can be rotated by the transposition mechanism 7 so that its liquid inlet 61 is aligned with the inside of the next liquid inlet channel 2 to continue the desalination operation, and the multi-stage permeation assembly 5 inside the previous liquid inlet channel 2 can be inspected and replaced.

[0090] The osmotic assembly outlet mechanism 4 can adjust the position of the multi-stage osmotic assembly 5 by driving the motor 41 and adjust the operating parameters according to the dilution effect.

[0091] Desalinated water collection and export:

[0092] The osmosis assembly outlet mechanism 4 inside the previous liquid inlet channel 2 is started, and the channel end hatch 11 at one end outside the liquid inlet channel 2 is opened. At this time, the multi-stage osmosis assembly 5 is pushed out, and the filter grid plate 51 and the reverse osmosis membrane 53 can be checked to ensure that there is no serious blockage or damage. According to the usage and water quality, the reverse osmosis membrane is replaced in time to maintain the best desalination effect.
