Abstract
Description
Technical Field
[0001] This utility model relates to the field of electro-adsorption desalination technology, and in particular to an electrode plate and desalination device for electro-adsorption. Background Technology
[0002] Electroadsorption desalination technology uses a direct current voltage to create an electrostatic field. When wastewater flows through electrode plates, charged particles in the water migrate towards the electrode plates with opposite charges, are adsorbed onto the surface of the plates, and become concentrated. This ultimately separates charged salts and colloidal particles from the water, resulting in desalinated reclaimed water. To improve the adsorption efficiency of the electrode plates for charged particles, metal mesh is usually placed on both sides of the electrode plates. However, in existing technologies, the metal mesh is typically placed in a closed metal grid cylinder, which is inconvenient for disassembly and deep cleaning. Therefore, developing a novel desalination device has become an urgent problem for those skilled in the art. Utility Model Content

[0023] like Figures 1 to 6 As shown, a desalination device includes a housing 1, an electrode plate body 2, a first fixing frame 203, a second fixing frame 204, and a metal wire mesh 205. The housing 1 is made of insulating material.
[0024] The housing 1 contains several electrode plate bodies 2, and clamping plates 201 are fixedly mounted on the electrode plate bodies 2. An insulating base 202 is fixedly mounted at the bottom of the housing 1, and the top of the insulating base 202 is connected to the clamping plates 201 on the electrode plate bodies 2 by bolts.
[0025] The electrode plate body 2 of the desalination device of this utility model is detachably mounted on the insulating base 202 by bolts, and each electrode plate body 2 can be disassembled independently.
[0026] The front end of the clamping plate 201 is bolted to a second fixing frame 204, and the rear end of the clamping plate 201 is bolted to a first fixing frame 203. Several layers of metal wire mesh 205 are fixedly arranged between the second fixing frame 204 and the first fixing frame 203. The design of multiple layers of metal wire mesh 205 can increase the contact area between the metal wire mesh 205 and the raw water.
[0027] The electrode plate body 2 has clamping plates 201 on both its left and right ends, and metal wire mesh 205 on both ends. The clamping plates 201 are made of metal to facilitate the conduction of electricity to the metal wire mesh 205. The metal wire mesh 205 of this desalination device is mounted on the clamping plates 201 of the electrode plate body 2 via a fixing frame, and the two are connected by bolts, facilitating the maintenance and replacement of the metal wire mesh 205.
[0028] The first fixing frame 203 and the second fixing frame 204 are vertically arranged on the clamping plate 201, and the first fixing frame 203 and the second fixing frame 204 are arranged in parallel.
[0029] The top of the electrode plate body 2 is connected to a DC power supply via a wire, and adjacent electrode plate bodies 2 are connected to different electrodes of the DC power supply.
[0030] A raw water inlet pipe 4 is located at the lower left corner of the housing 1, and an insulating perforated plate 3 that mates with the raw water inlet pipe 4 is located at the left end of the housing 1. A first conductivity meter 401 is installed on the raw water inlet pipe 4, and a raw water outlet pipe 5 is located at the upper right corner of the housing 1. A second conductivity meter 501 is installed on the raw water outlet pipe 5. The first conductivity meter 401 and the second conductivity meter 501 are used to perform online detection of the raw water and the treated raw water, respectively, to determine the electro-adsorption effect of the electro-adsorption unit.
[0031] A backwashing mechanism 6 is provided at the top of the housing 1. The backwashing mechanism 6 includes a nozzle 601 and a water supply pipe 602. The nozzle 601 cooperates with the metal wire mesh 205 on the electrode plate body 2, and the top of the nozzle 601 is connected to the water supply pipe 602. A drain pipe 603 is provided at the lower right corner of the housing 1. The desalination device of this utility model has a nozzle 601 at the top that cooperates with the metal wire mesh 205. During backwashing, the liquid flows along the fixed frame and clamp 201 from the top to the bottom of the metal wire mesh 205, resulting in high cleaning efficiency.
[0032] After being powered by DC power, the electrode plate body 2 is charged with positive and negative charges respectively. Raw water flows in from the raw water inlet pipe 4 in the lower left corner of the tank 1. After passing through the insulating sieve plate 3, it slowly flows through the channel formed by the electrode plate body 2. The ions and charged particles in the raw water move towards the electrode plate body 2 with opposite charges in the electric field. They are then adsorbed on the electrode plate body 2 and stored in the dual electric field. The desalinated water flows out from the raw water outlet pipe 5 in the upper right corner of the tank 1.
[0033] As the number of adsorbed ions increases, the conductivity of the effluent after electro-adsorption treatment also gradually increases. When the conductivity of the effluent is 80% of that of the influent, it indicates that the adsorption capacity of the electrode plate body 2 is approaching saturation. At this time, close the raw water inlet pipe 4 and the raw water outlet pipe 5, disconnect the DC power supply, and short-circuit the adjacent electrode plate bodies 2 with a wire.
[0034] When the nozzle 601 of the backwashing mechanism 6 is opened, the electric field between the electrode plate bodies 2 is eliminated, and the ions stored in the dual electric field return to the channel and are discharged with the water flow, thus regenerating the electrode plate bodies 2.
[0035] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
