Description

Technical Field

[0001] This utility model relates to the field of electro-desalination technology, and in particular to an EDI electro-desalination device. Background Technology

[0002] Electrodialysis (EDI) is an advanced water treatment technology that combines electrodialysis and ion exchange technologies. EDI achieves the directional migration of ions in water under the action of an electric field by selectively permeating cation and anion membranes and exchanging ions in water with ion exchange resins. Under the action of an electric field, water molecules generate hydrogen ions and hydroxide ions, which continuously regenerate the ion exchange resins. This allows the EDI water treatment process to continuously produce high-quality ultrapure water without the need for acid or alkali chemical regeneration.

[0003] Existing electrostatic desalination devices have a relatively simple structure, in which the anion and cation membranes are usually fixedly installed on both sides of the water flow channel. This results in faster ion adsorption near the sides of the water flow and slower ion adsorption near the center. This undoubtedly increases the water flow processing time, reduces the device's efficiency, and makes it impractical. Therefore, we propose an EDI electrostatic desalination device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Existing electro-desalination devices have a relatively simple structure, in which the anion and cation membranes are usually fixedly installed on both sides of the water flow channel. This results in faster ion adsorption near the sides of the water flow and slower ion adsorption near the center, which undoubtedly increases the water flow processing time, reduces the device's efficiency, and makes it impractical.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An EDI (Electro-Deionization) device includes a tank, wherein adsorption mechanisms are symmetrically installed inside the tank near the front and back sides.

[0007] The adsorption mechanism includes a motor, the output end of which is mounted at the top of the tank facing the bottom. The output end of the motor extends into the interior of the tank and is fixedly connected to a connecting shaft. Several adsorption components are mounted around the periphery of the connecting shaft.

[0008] As a preferred embodiment of this utility model, the back of the tank is provided with a water inlet and the front of the tank is provided with a water outlet, and the tank, the water inlet and the water outlet are connected.

[0009] The technical effect of adopting the above-mentioned further solution is that the water flows into the tank 1 through the inlet, and after being adsorbed by the anion membrane and the cation membrane, it flows out through the outlet to complete the treatment process.

[0010] As a preferred embodiment of this utility model, a discharge pipe is installed at the bottom of the tank corresponding to the connecting shaft. The connecting shaft is a hollow structure, which is inserted into the top of the discharge pipe and connected to the discharge pipe. A sealing ring is bonded to the end of the connecting shaft near the bottom where it contacts the discharge pipe.

[0011] The technical effect of adopting the above-mentioned further solution is that the concentrated water produced after decomposition enters the interior of the connecting shaft and is discharged through the discharge pipe. The sealing ring can improve the sealing effect, prevent water inside the tank from flowing out from the joint between the connecting shaft and the discharge pipe, and improve the stability of use.

[0012] As a preferred embodiment of this utility model, the bottom of the tank is welded with support feet near the four corners.

[0013] The technical advantage of adopting the above-mentioned further solution is that the distance between the tank and the ground can be increased by the support feet, thereby improving practicality.

[0014] As a preferred embodiment of this utility model, a dust cover is installed around the motor and at the top of the tank.

[0015] The technical effect of adopting the above-mentioned further solution is that the dust cover can prevent dust from entering the motor, thereby improving the service life of the motor.

[0016] As a preferred embodiment of this utility model, a plurality of limiting rods are welded around the contact point between the top end of the connecting shaft and the top end of the tank body, and the limiting rods are slidably connected to the tank body.

[0017] The technical effect of adopting the above-mentioned further solution is that the limiting rod can limit the rotating connecting shaft, prevent it from deviating, and improve the stability of use.

[0018] As a preferred embodiment of this utility model, the adsorption component includes a partition, a membrane is installed inside the partition, and the partition is connected to a connecting shaft.

[0019] The technical effect of adopting the above-mentioned further solution is that, under the action of the electrode, ions in the water can be adsorbed through the membrane, and the concentrated ion water is discharged into the connecting shaft through the partition, and finally flows out of the tank through the discharge pipe.

[0020] As a preferred embodiment of this utility model, the membrane is divided into an anion membrane and an ion membrane, and they are installed alternately inside adjacent partitions.

[0021] The technical advantage of adopting the above-mentioned further solution is that the alternating installation of anion and cation membranes allows for better and more uniform adsorption of anions and cations in the water, thereby improving the adsorption effect and working efficiency.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] In this invention, through the design of the tank and the adsorption mechanism, the motor can drive the connecting shaft to rotate, causing the adsorption component to rotate at a uniform speed inside the tank. This allows the adsorption component to have more uniform contact with the water flow, increasing the processing speed of ions in the water flow. Compared with traditional equipment, this shortens the processing time, greatly improves work efficiency, and effectively enhances practicality. Attached Figure Description

[0034] like Figure 1-4 As shown, this utility model provides a technical solution: an EDI electro-desalination treatment device, including a tank 1. Adsorption mechanisms 2 are symmetrically installed near the front and back of the tank 1. The adsorption mechanism 2 includes a motor 201. The output end of the motor 201 is installed at the top of the tank 1 facing the bottom. The output end of the motor 201 extends into the tank 1 and is fixedly connected to a connecting shaft 202. Several adsorption components 203 are installed around the periphery of the connecting shaft 202. The rotation of the motor 201 can drive the connecting shaft 202 to rotate, thereby causing the connecting shaft 202 to drive the adsorption components 203 to rotate at a uniform speed inside the tank 1.

[0035] Example 2

[0036] like Figure 1-4As shown, a water inlet 101 is provided on the back of the tank 1, and a water outlet 102 is provided on the front of the tank 1. The tank 1, the water inlet 101, and the water outlet 102 are connected. Water flows into the tank 1 through the water inlet 101. After being adsorbed by the anion membrane and the cation membrane, it flows out through the water outlet 102, completing the treatment process. A discharge pipe 103 is installed at the bottom of the tank 1 corresponding to the connecting shaft 202. The connecting shaft 202 is a hollow structure and is inserted into the top of the discharge pipe 103 and connected to the discharge pipe 103. The connecting shaft 202 is close to the... A sealing ring is bonded to the end near the bottom where it contacts the discharge pipe 103. The concentrated water produced after decomposition enters the connecting shaft 202 and is discharged through the discharge pipe 103. The sealing ring improves the sealing effect, preventing water inside the tank 1 from flowing out from the joint between the connecting shaft 202 and the discharge pipe 103, thus improving operational stability. Support feet 104 are welded to the bottom of the tank 1 near the four corners. These support feet 104 raise the distance between the tank 1 and the ground, improving practicality. The motor 201 is located around... A dust cover 2011 is installed at the top of the tank 1. The dust cover 2011 can prevent dust from entering the motor 201, thereby improving the service life of the motor 201. Several limiting rods 2021 are welded around the contact point between the top of the connecting shaft 202 and the top of the inner part of the tank 1. The limiting rods 2021 are slidably connected to the tank 1. The limiting rods 2021 can limit the rotation of the connecting shaft 202 to prevent it from deviating and improve the stability of use. The adsorption component 203 includes a partition 2031. The inner part of the partition 2031... The unit is equipped with a membrane 2032, and the partition 2031 is connected to the connecting shaft 202. Under the action of the electrodes, the membrane 2032 can adsorb ions in the water, and the concentrated ion water is discharged into the connecting shaft 202 through the partition 2031, and finally flows out of the tank 1 through the discharge pipe 103. The membrane 2032 is divided into anion membrane and cation membrane, and is installed alternately inside the adjacent partition 2031. The alternating installation of anion membrane and cation membrane can better and more uniformly adsorb anions and cations in the water, thereby improving the adsorption effect and working efficiency.

[0037] The working process of this utility model is as follows: When using an EDI electro-desalination device for ion adsorption treatment, firstly, an external water supply device injects water into the tank 1 through the inlet 101. The motor 201 drives the connecting shaft to rotate at a constant speed, causing the connecting shaft to drive the adsorption component 203 to rotate inside the tank 1. This allows the adsorption component 203 to contact the water flow more evenly, thereby adsorbing anions and cations under the action of the electrodes and allowing them to pass through the corresponding anion and cation membranes into the partition 2031. The water then flows through the connecting shaft 202 and is discharged through the discharge pipe 103. Compared with the treatment method of traditional equipment, this method shortens the treatment time, greatly improves the work efficiency, and effectively enhances practicality. Finally, the treated water is discharged through the outlet 102, completing the entire treatment process.
