Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a self-cleaning electroadsorption treatment device. Background Technology

[0002] Electro-adsorption deionization technology is a novel water treatment method that has been developed in recent years. Its principle is to apply an electrostatic field to a saline aqueous solution, forcing the ions in it to move toward the charged electrode and be bound in the double electric layer formed on the electrode surface, thereby achieving the effect of removing ions.

[0003] However, in the application of traditional electro-adsorption deionization technology, electricity is usually applied to each electrode plate, and the water flows parallel to the electrode plate, with water entering and exiting in a horizontal flow. This results in the water flowing directly through the electrode plate unit in the entire electro-adsorption device, with short adsorption time and low effective contact area, which limits the treatment effect on high-concentration saline wastewater.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a self-cleaning electro-adsorption treatment device. Utility Model Content

[0005] The purpose of this invention is to provide a self-cleaning electro-adsorption treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning electro-adsorption treatment device, comprising a housing and a continuous flow electro-adsorption assembly. The housing is equipped with the continuous flow electro-adsorption assembly, which includes a unidirectional electrode plate, a double-sided electrode plate, a water channel, terminals, a water baffle, wires, and an automatic phase-reversing power supply. The unidirectional electrode plate is fixed to the inner walls of opposite sides of the housing, and double-sided electrode plates are spaced apart inside the unidirectional electrode plates on both sides. The double-sided electrode plate has a water channel on its side, and terminals are provided on the top of both the double-sided electrode plate and the unidirectional electrode plate. A water baffle is fitted over the terminals, and wires are connected between adjacent terminals, and the wires are connected to the positive and negative output terminals of the automatic phase-reversing power supply.

[0007] Furthermore, each unidirectional electrode plate has a terminal block on both sides of its top, and each double-sided electrode plate has a terminal block on only one side. The water passage and terminal block between adjacent double-sided electrode plates are located on different sides.

[0008] Furthermore, the unidirectional electrode plate is connected to the negative terminal of an automatic phase-commutation power supply via a terminal at one end, and is also connected to the negative terminal of an automatic phase-commutation power supply via a terminal at the other end, and is connected to the positive terminal of an automatic phase-commutation power supply via a terminal at the other end.

[0009] Furthermore, the leftmost unidirectional electrode plate is connected to the side end of the gap between it and the adjacent double-sided electrode plate by a water inlet pipe, and a filter screen is provided at the inlet of the water inlet pipe.

[0010] Furthermore, the rightmost unidirectional electrode plate is connected to the side end of the gap between it and the adjacent double-sided electrode plate by a water outlet pipe, and a conductivity meter is installed at the water outlet pipe.

[0011] Furthermore, symmetrical limit plates are fixed to the inner walls of the opposite sides of the housing, and the "U"-shaped openings of the limit plates are inserted into and limited by the corresponding double-sided electrode plates.

[0012] Furthermore, a notch is provided at the bottom end of the gap between the opposing surfaces of the adjacent double-sided electrode plates, and the notch is connected to the slag discharge pipe, which is connected to the slag discharge pump.

[0013] Furthermore, a water tank is fixed to the side wall of the box, and a water pump is connected to the top of the water tank. The output end of the water pump is connected to a spray pipe that spans the opening at the top of the box.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In use, the unidirectional electrode plate is electrically connected to a group of spaced-apart double-sided electrode plates via a terminal at one end, and then connected to the negative terminal of the automatic phase-switching power supply. The unidirectional electrode plate is also electrically connected to another group of spaced-apart double-sided electrode plates via a terminal at the other end, and then connected to the positive terminal of the automatic phase-switching power supply. This forms multiple adsorption units between the unidirectional electrode plate and adjacent double-sided electrode plates, as well as between adjacent double-sided electrode plates. Ions in the water are adsorbed onto the electrode plates by an electrostatic field. In addition, the water passage between adjacent double-sided electrode plates is designed on different sides, so that the water flows in an S-shaped path to achieve multi-stage adsorption and achieve a better desalination effect.

[0016] 2. When this utility model is in use, when the conductivity meter installed at the water outlet pipe detects that the adsorption capacity of the electrode plate has reached saturation, the automatic phase-switching power supply automatically switches the power polarity, and the pure water spray from the spray pipe causes the ions adsorbed on the electrode plate to be desorbed and washed away. Furthermore, through the notch opened at the bottom of the gap between the opposite surfaces of the adjacent double-sided electrode plates, the impurities are discharged by the slag discharge pump connected to the slag discharge pipe, thus completing the regeneration of the electrode.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 3 As shown, a self-cleaning electro-adsorption treatment device includes a housing 1 and a continuous flow electro-adsorption assembly 2. The continuous flow electro-adsorption assembly 2 is installed inside the housing 1. The continuous flow electro-adsorption assembly 2 includes a unidirectional electrode plate 201, a double-sided electrode plate 202, a water channel 203, a terminal block 204, a water baffle 205, a wire 206, and an automatic phase-reversing power supply 207. The unidirectional electrode plates 201 are fixed to the inner walls of opposite sides of the housing 1, and the double-sided electrode plates 202 are spaced apart inside the unidirectional electrode plates 201. The double-sided electrode plates 202 have water channels 203 on their sides, and the tops of both the double-sided electrode plates 202 and the unidirectional electrode plates 201 are provided with terminal blocks 204. The terminal blocks 204 are covered with water baffles 205, and adjacent terminal blocks are connected to each other. A wire 206 is connected between the posts 204, and the wire 206 is connected to the positive and negative output terminals of the automatic phase-commutation power supply 207. The top of the unidirectional electrode plate 201 is provided with terminals 204 on both sides, and each double-sided electrode plate 202 is provided with terminals 204 on only one side. The water passage trough 203 and terminals 204 between adjacent double-sided electrode plates 202 are located on different sides. The unidirectional electrode plate 201 is electrically connected to one of the spaced double-sided electrode plates 202 through the terminals 204 at one end, and then connected to the negative terminal of the automatic phase-commutation power supply 207. The unidirectional electrode plate 201 is electrically connected to another spaced double-sided electrode plate 202 through the terminals 204 at the other end, and then connected to the positive terminal of the automatic phase-commutation power supply 207.

[0023] The specific operation is as follows: The unidirectional electrode plate 201 is connected to one of the spaced-apart double-sided electrode plates 202 via the terminal 204 at one end, and then connected to the negative terminal of the automatic phase-switching and reversing power supply 207. The unidirectional electrode plate 201 is connected to another spaced-apart double-sided electrode plate 202 via the terminal 204 at the other end, and then connected to the positive terminal of the automatic phase-switching and reversing power supply 207. In this way, multiple adsorption units are formed between the unidirectional electrode plate 201 and the adjacent double-sided electrode plate 202, and between the adjacent double-sided electrode plates 202. Ions in the water are adsorbed onto the electrode plates by the electrostatic field. In addition, the water passage trough 203 between the adjacent double-sided electrode plates 202 is designed on different sides, so that the water flows in an S-shaped route to achieve multi-stage adsorption and achieve better desalination effect.

[0024] like Figures 1 to 2 As shown, the leftmost unidirectional electrode plate 201 and the adjacent double-sided electrode plate 202 are connected to the side end of the gap between them by a water inlet pipe 3, and a filter screen is provided at the inlet of the water inlet pipe 3. The rightmost unidirectional electrode plate 201 and the adjacent double-sided electrode plate 202 are connected to the side end of the gap between them by a water outlet pipe 4, and a conductivity meter 5 is installed at the water outlet pipe 4. Limiting plates 6 are symmetrically fixed on the inner walls of the opposite sides of the box 1, and the "U"-shaped openings of the limiting plates 6 are inserted into and limited by the corresponding double-sided electrode plates 202. The bottom end of the gap between the opposite surfaces of the adjacent double-sided electrode plates 202 is provided with a notch 7, and the notch 7 is connected to the slag discharge pipe 8. The slag discharge pipe 8 is connected to the slag discharge pump 9. A water tank 10 is fixed on the side wall of the box 1, and a water supply pump 11 is connected to the top of the water tank 10. The output end of the water supply pump 11 is connected to a spray pipe 12 that spans the top opening of the box 1.

[0025] The specific operation is as follows: When the conductivity meter 5 installed at the outlet pipe 4 detects that the adsorption capacity of the electrode plate has reached saturation, the automatic phase-switching power supply 207 automatically switches the power polarity, and the pure water spray from the spray pipe 12 causes the ions adsorbed on the electrode plate to be desorbed and washed away. Furthermore, through the notch 7 at the bottom of the gap between the opposite surfaces of the adjacent double-sided electrode plates 202, the impurities are discharged by the slag discharge pump 9 connected to the slag discharge pipe 8, thus completing the regeneration of the electrode.

[0026] Working principle: When using this self-cleaning electroadsorption treatment device, the unidirectional electrode plate 201 is electrically connected to a group of spaced-apart double-sided electrode plates 202 via one end terminal 204, and then connected to the negative terminal of the automatic phase-commutation power supply 207. The unidirectional electrode plate 201 is also electrically connected to another group of spaced-apart double-sided electrode plates 202 via the other end terminal 204, and then connected to the positive terminal of the automatic phase-commutation power supply 207. This creates multiple adsorption units between the unidirectional electrode plate 201 and adjacent double-sided electrode plates 202, and between adjacent double-sided electrode plates 202. The electrostatic field adsorbs ions from the water onto the electrode. Furthermore, this application also designs the water passage trough 203 between adjacent double-sided electrode plates 202 on different sides, so that the water flows in an S-shaped route to achieve multi-stage adsorption and achieve better desalination effect. When the conductivity meter 5 installed at the outlet pipe 4 detects that the adsorption capacity of the electrode plate has reached saturation, the automatic phase-switching reverse power supply 207 automatically switches the power polarity, and the pure water spray from the spray pipe 12 makes the ions adsorbed on the electrode plate desorbed and washed away. In addition, the impurities are discharged by the slag discharge pump 9 connected to the slag discharge pipe 8 through the notch 7 at the bottom of the gap between the opposite surfaces of the adjacent double-sided electrode plates 202, thus completing the regeneration of the electrode.
