Detailed Description

The following detailed description of embodiments of the utility model refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the utility model, are given by way of illustration and explanation only, not limitation.

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

In embodiments of the utility model, where the context requires otherwise, the use of directional terms such as "upper, lower, top and bottom" is generally intended in the orientation shown in the drawings or the positional relationship of the various components in a vertical, vertical or gravitational orientation.

The utility model will be described in detail below with reference to exemplary embodiments and with reference to the accompanying drawings.

As shown in fig. 1 to 14, an exemplary embodiment of the present invention provides an electrolysis apparatus including a water flow passage 1, a plurality of electrodes, and an acid-base separator. Wherein the plurality of electrodes are capable of electrolyzing a water flow in the water flow channel 1 and comprise a plurality of anodes and a plurality of cathodes arranged in pairs. The acid-base membrane is used for separating the electrolyzed water flow in the water flow channel 1 by acid-base, and can be a proton membrane, an ultrafiltration membrane and the like. The water passing channel 1 extends in a winding way in the electrolysis device, and under the electrolysis action of the electrode and the acid-base separation action of the acid-base membrane, an acidic water channel and an alkaline water channel are formed in the water passing channel 1, namely the acidic water channel and the alkaline water channel respectively extend in a winding way at two sides of the acid-base membrane.

When the electrolysis device in the exemplary embodiment is adopted, the water flowing channel extends in a roundabout manner, so that the whole length of the channel is greatly prolonged, and when water flows in the channel in a roundabout manner, even if the water flows at a high speed, the water can be ensured to stay in the channel for a long time, namely, the electrolysis time is effectively prolonged, and the electrolysis effect is remarkably improved. The electrolysis apparatus of the present exemplary embodiment has a smaller volume under the same electrolysis effect as compared to the conventional electrolysis apparatus, thereby having advantages of space saving, cost saving, and the like.

In one embodiment, the electrolyzer comprises a plurality of flow-path walls 2, at least part of the wall body area of the flow-path walls 2 is formed as an electrode, i.e. the flow-path walls 2 can be integrally formed as electrodes, or can be partially formed as electrodes, and can be partially made of other materials to realize the supporting function and reduce the cost.

The polarity of the electrode portions on the same flow path wall 2 is the same, so that the flow path wall 2 includes a plurality of anode flow path walls formed with anodes and a plurality of cathode flow path walls formed with cathodes. In order to ensure more disposable electrolyzed water, a plurality of anode runner walls and a plurality of cathode runner walls can be arranged in turn, and acid-base diaphragms are arranged between the adjacent anode runner walls and cathode runner walls so as to limit a plurality of acidic water runners and a plurality of alkaline water runners which are arranged in turn among the plurality of runner walls. In other words, by arranging the anode runner walls and the cathode runner walls in turn and alternately, a multi-runner structure can be formed in the electrolysis device, and the runners are compactly arranged, which is beneficial to reducing the volume of the device.

To simplify the apparatus structure, it is preferable that only a single apparatus water inlet, a single apparatus acidic water outlet and a single apparatus basic water outlet be provided, each acidic water flow passage communicating the apparatus water inlet and the apparatus acidic water outlet, and each basic water flow passage communicating the apparatus water inlet and the apparatus basic water outlet. During electrolysis, water flows firstly flow from the water inlet of the device to the plurality of water passing flow channels 1, under the action of electrolysis and acid-base separation, the plurality of water passing flow channels 1 are formed into a plurality of acidic water flow channels and a plurality of alkaline water flow channels which are alternately arranged in sequence, acidic water flowing out of the plurality of acidic water flow channels passes through the acidic water outlet of the device and is discharged out of the device, and alkaline water flowing out of the alkaline water flow channels passes through the alkaline water outlet of the device and is discharged out of the device.

In an embodiment in which a multi-channel structure is formed by the channel wall 2, referring to fig. 1 to 9, the channel wall 2 has a plate shape and includes a first wall surface 21, a second wall surface 22, a channel inlet 11, and a boundary wall portion 23. The first wall surface 21 and the second wall surface 22 are flat surfaces, the flow channel inlet 11 penetrates through the first wall surface 21 and the second wall surface 22, the boundary wall portion 23 protrudes from the second wall surface 22 and is coiled and extended from the outer edge portion of the flow channel inlet 11 to the outer edge portion of the second wall surface 22, for example, the boundary wall portion is circular, square or triangular in spiral extension, and correspondingly, the flow channel wall 2 can be in a circular plate shape, a square plate shape, a triangular plate shape and the like.

By arranging the plurality of flow path walls 2 in the above-described structure in a stacked manner in order (i.e., a plurality of anode flow path walls and a plurality of cathode flow path walls are alternately arranged in a stacked manner in order), the water passing flow path 1 can be formed between the adjacent flow path walls 2. Specifically, the second wall surface 22 and the boundary wall portion 23 of one of the adjacent flow channel walls 2 and the first wall surface 21 of the other define the water passing flow channel 1, the flow channel outlet 12 of the water passing flow channel 1 is formed at the coiled outer end of the corresponding boundary wall portion 23, the plurality of flow channel inlets 11 are communicated with each other, and each flow channel inlet 11 is covered with an acid-base diaphragm.

The water flow flows in through the flow channel inlets 11 on the outermost flow channel wall 2 and then is divided into the water passing flow channels 1 through the plurality of flow channel inlets 11 which are communicated with each other, the water flow in each water passing flow channel 1 flows in a circuitous way under the flow guiding action of the boundary wall part 23, is fully electrolyzed in the circuitous way, is formed into acid water or alkaline water under the action of the acid-base diaphragm, and finally flows out from the corresponding flow channel outlets 12.

More specifically, the flow channel outlet 12 includes an acid water flow channel outlet of the acid water flow channel and a basic water flow channel outlet of the basic water flow channel. In order to ensure that the acidic water and the alkaline water are isolated from each other when flowing out, the outlets of the acidic water flow passage and the alkaline water flow passage are arranged at intervals along the circumferential direction of the flow passage wall 2. For example, since the acid water flow passage and the alkaline water flow passage are adjacently disposed, the winding directions of the adjacent boundary wall portions 23 may be oppositely disposed (refer to fig. 8), thereby facilitating the separation of the acid water flow passage outlet and the alkaline water flow passage outlet in the circumferential direction.

Further, referring to fig. 5 and 6, along the circumferential direction of the flow path wall 2, the plurality of acid water flow path outlets are aligned and the plurality of alkaline water flow path outlets are aligned, so that the acid water and the alkaline water are discharged from the acid water outlet of the same apparatus and the alkaline water outlet of the same apparatus, respectively. In addition, the plurality of flow channel inlets 11 are arranged in an aligned manner along the stacking direction of the plurality of flow channel walls 2, so that water flows into the flow channel walls 2 at the outermost layer and then is quickly divided into the water passing flow channels 1. Preferably, the flow channel inlet 11 of each flow channel wall 2 is located at the center position, and the boundary wall portion 23 is coiled from the middle position to the edge position of the flow channel wall 2, so that a longer circuitous path is provided, and the electrolysis effect on the water flow is further improved.

In addition to the above configuration, a cylindrical case is further provided in the electrolysis apparatus. Referring to fig. 2, the peripheral wall of the cylindrical housing is formed with a device acidic water outlet and a device alkaline water outlet which are circumferentially spaced, and at this time, each acidic water flow passage outlet is communicated to the device acidic water outlet, and each alkaline water flow passage outlet is communicated to the device alkaline water outlet. Therefore, the plurality of acid water flow passage outlets are arranged in an aligned mode and are communicated to the acid water outlet of the single device, and the plurality of alkaline water flow passage outlets are arranged in an aligned mode and are communicated to the alkaline water outlet of the single device, so that the electrolysis device has a simple water outlet structure, the size of the device is reduced, the processing cost is reduced, the installation space is saved, and the like.

Further, the cylindrical shell may include the sleeve peripheral wall portion 4, the first end plate portion 5, and the second end plate portion 6, which are formed separately from each other. Referring to fig. 3, the sleeve peripheral wall portion 4 is open at both axial ends and is sealingly closed by the first end plate portion 5 and the second end plate portion 6, respectively, the inner end surface of the first end plate portion 5 and the second wall surface 22 and the boundary wall portion 23 of the adjacent flow passage wall 2 define the water passage 1 at the end, and the second end plate portion 6 is formed with a device water inlet which communicates with the flow passage inlet 11 in the adjacent flow passage wall 2. When the flow channel inlet 11 in the flow channel wall 2 is arranged in a central position, the device water inlet is arranged in a central position in the second end plate portion 6 so as to be aligned with the flow channel inlet 11.

The mutual isolation of the acid water outlet of the device and the alkaline water outlet of the device can be realized in different ways. For example, a water retaining rib 41 may be provided between the acidic water outlet and the alkaline water outlet, specifically, referring to fig. 4 and 9, the inner peripheral wall of the cylindrical housing is formed with a first water retaining rib, a second water retaining rib and a third water retaining rib which extend along the axial direction and are sequentially arranged at intervals along the circumferential direction, the first water retaining rib, the second water retaining rib and the third water retaining rib all seal the outer peripheral wall of the flow channel wall 2, and at this time, a circulation gap 3 between the adjacent water retaining ribs 41 is formed between the outer peripheral wall of the flow channel wall 2 and the inner peripheral wall of the cylindrical housing. Specifically, in the circumferential interval area of the first water retaining rib and the second water retaining rib, an acidic water circulation gap is formed between the flow channel wall 2 and the cylindrical shell, and the acidic water flow channel outlet, the acidic water circulation gap and the device acidic water outlet are communicated in an aligned mode. In the circumferential interval area of the second water retaining rib and the third water retaining rib, an alkaline water circulation gap is formed between the flow channel wall 2 and the cylindrical shell, and an alkaline water flow channel outlet, the alkaline water circulation gap and the alkaline water outlet of the device are communicated in an aligned mode. It can be seen that the mutual isolation of the acid water outlet and the alkaline water outlet of the device can be realized by arranging the water retaining rib 41.

In order to ensure the stable installation of the flow passage wall 2 and the cylindrical shell, a limiting structure for limiting the relative displacement generated between the flow passage wall 2 and the cylindrical shell is arranged in the electrolysis device. For example, referring to fig. 4 and 9, a plurality of positioning grooves 42 which are outwardly concave and are sequentially arranged at intervals in the circumferential direction are formed on the inner circumferential wall of the cylindrical housing, positioning protrusions 24 which are outwardly convex are formed on the outer circumferential wall of the flow passage wall 2, at least two positioning protrusions 24 which are circumferentially arranged at intervals are formed in the same flow passage wall 2, and when the flow passage wall 2 is installed in the cylindrical housing, the positioning protrusions 24 can be inserted into the positioning grooves 42 which are oppositely arranged, thereby preventing relative displacement between the flow passage wall 2 and the cylindrical housing.

When a cylindrical case is provided, the flow path wall 2 can be electrically connected to an external power supply by providing the through groove 43 in the cylindrical case. For example, referring to fig. 1 and 3, a through groove 43 is formed in the peripheral wall of the cylindrical case, a terminal 25 protruding outward is connected to the peripheral wall of the flow path wall 2, and when the flow path wall 2 is fitted into the cylindrical case, the terminal 25 is passed out of the cylindrical case through the through groove 43, and can be connected to an external power supply. Preferably, in order to simplify the structure, the terminals 25 include a plurality of anode terminals connected to the outer peripheral walls of the plurality of anode flow path walls in a one-to-one correspondence, and a plurality of cathode terminals connected to the outer peripheral walls of the plurality of cathode flow path walls in a one-to-one correspondence, first through grooves and second through grooves extending in the axial direction and arranged at intervals in the circumferential direction are formed on the peripheral walls of the cylindrical housing, the plurality of anode terminals are aligned in the circumferential direction and penetrate the first through grooves outwards, and the plurality of cathode terminals are aligned in the circumferential direction and penetrate the second through grooves outwards.

In another embodiment of forming a multi-channel structure by the channel walls 2, referring to fig. 10 to 14, the channel walls 2 include a central channel wall 26 having a cylindrical shape and a plurality of outer channel walls having a cylindrical shape, the outer channel walls include a peripheral channel wall 29 and a plurality of peripheral channel walls, and each of the central channel wall 26 and the peripheral channel walls is formed with a boundary protrusion 210 extending circumferentially around the outer peripheral wall of the channel wall. For example, the center runner wall 26 is cylindrical, the peripheral runner wall is cylindrical, and the boundary protrusion 210 extends in a spiral shape. The central flow channel wall 26, the plurality of peripheral flow channel walls and the edge flow channel wall 29 are sequentially sleeved from inside to outside, and the peripheral wall of one of the adjacent flow channel walls 2 and the boundary protrusion 210 define the water flow channel 1 together with the inner peripheral wall of the other flow channel wall. As can be seen from the foregoing, due to the different polarities of the two adjacent flow passage walls 2 and the effect of the acid-base diaphragm, a plurality of acidic water flow passages and a plurality of alkaline water flow passages alternately arranged in sequence can also be formed in the plurality of flow passage walls 2 forming the sleeving structure, and the specific arrangement manner of the acid-base diaphragm will be described below.

In order to prolong the stay time of the water flow in the water flowing channel 1 as much as possible, the axial two ends of the channel wall 2 are respectively set as the water inlet end of the channel wall and the water outlet end of the channel wall, and at the moment, the boundary bulge part 210 extends in the whole axial length range of the channel wall 2, so that the channel has a longer length.

If the acidic water in each acidic water flow passage is to be discharged through the same acidic water outlet of the device and the alkaline water in each alkaline water flow passage is to be discharged through the same alkaline water outlet of the device, the following embodiments can be implemented.

Specifically, in this embodiment, the flow channel wall outlet ends of all the outer flow channel walls are closed by forming flow channel wall end walls 211, the flow channel wall end walls 211 are connected to flow channel outlet pipes 212 extending axially outwardly on the outer flow channel walls adjacent to the center flow channel wall 26, and the flow channel wall end walls 211 are connected to flow channel outlet pipes 212 extending axially outwardly on the remaining outer flow channel walls and are formed with outlet pipe passing holes 213 disposed spaced from the flow channel outlet pipes 212.

Among any three external flow channel walls which are continuously sleeved from inside to outside, the flow channel water outlet pipe 212 on the innermost external flow channel wall penetrates through the water outlet pipe penetrating hole 213 on the middle external flow channel wall outwards and penetrates into the flow channel water outlet pipe 212 on the outermost external flow channel wall. The water outlet pipe 212 of the flow channel on the middle external flow channel wall passes through the water outlet pipe through hole 213 on the outermost external flow channel wall, and a flow gap 3 between the water passing flow channel 1 and the water outlet pipe 212 is formed between the adjacent flow channel walls 2.

To facilitate an understanding of the above principles, reference is made to the following illustrative embodiments.

In the illustrated embodiment, the runner wall 2 includes a central runner wall 26, a first peripheral runner wall 27, a second peripheral runner wall 28, and an edge runner wall 29, which are sequentially connected from inside to outside. Wherein, the runner outlet pipe 212 on the first peripheral runner wall 27 passes through the outlet pipe passing hole 213 on the second peripheral runner wall 28 and passes through the runner outlet pipe 212 on the edge runner wall 29. The outlet pipe 212 of the second peripheral channel wall 28 passes through the outlet pipe passing hole 213 of the edge channel wall 29.

A first flow gap is formed between the central flow path wall 26 and the first peripheral flow path wall 27, a second flow gap is formed between the first peripheral flow path wall 27 and the second peripheral flow path wall 28, and a third flow gap is formed between the second peripheral flow path wall 28 and the edge flow path wall 29. The water in the first flow-through gap is of the same type as the water in the third flow-through gap, i.e. either being acidic water or being alkaline water, whereas the water in the first flow-through gap is of a different type than the water in the second flow-through gap, e.g. alkaline water when the water in the first flow-through gap is acidic water.

More specifically, the water in the first circulation gap flows out from the flow channel outlet pipe 212 on the first peripheral flow channel wall 27, the water in the third circulation gap flows out from the flow channel outlet pipe 212 on the edge flow channel wall 29, and since the flow channel outlet pipe 212 on the first peripheral flow channel wall 27 penetrates into the flow channel outlet pipe 212 on the edge flow channel wall 29, the two flow channel outlet pipes 212 can be sleeved at intervals, so that it can be ensured that the water in the first circulation gap and the water in the third circulation gap both flow out from the flow channel outlet pipes 212 on the edge flow channel wall 29 from the appearance. While the water in the second flow gap flows out of the channel outlet pipe 212 of the second surrounding channel wall 28.

In other words, when the outer nozzle of one of the runner outlet pipe 212 on the edge runner wall 29 and the runner outlet pipe 212 on the second surrounding runner wall 28 is formed as the device acidic water outlet, the outer nozzle of the other is formed as the device alkaline water outlet.

It can be seen that, since the flow channel outlet pipe 212 on the second peripheral flow channel wall 28 and the flow channel outlet pipe 212 on the edge flow channel wall 29 are isolated from each other, it can be ensured that the acidic water and the alkaline water flow out of the apparatus are isolated from each other, and it is ensured that the acidic water in each acidic water flow channel flows out from the acidic water outlet of the same apparatus, and the alkaline water in each alkaline water flow channel flows out from the alkaline water outlet of the same apparatus.

Referring to fig. 13 and 14, the bottom ends of the central flow path wall 26, the first peripheral flow path wall 27 and the second peripheral flow path wall 28 are respectively formed with a support portion 214, the support portion 214 of the central flow path wall 26 abuts against the flow path wall end wall 211 of the first peripheral flow path wall 27, the support portion 214 of the first peripheral flow path wall 27 abuts against the flow path wall end wall 211 of the second peripheral flow path wall 28, and the support portion 214 of the second peripheral flow path wall 28 abuts against the flow path wall end wall 211 of the edge flow path wall 29, so as to respectively form the first flow gap, the second flow gap and the third flow gap, thereby ensuring the conduction between each water passing flow path 1 and the corresponding flow path outlet pipe 212.

As described above, since one axial end of the flow channel wall 2 is formed as the flow channel wall water inlet end, referring to fig. 11 and 12, the flow channel wall water inlet end of the outer flow channel wall is axially opened, and the flow channel inlet 11 is formed between the adjacent flow channel wall water outlet ends. Under the structure, in order to form a plurality of acidic water flow channels and a plurality of alkaline water flow channels which are alternately arranged in sequence, an acid-base diaphragm can be covered on each flow channel inlet 11.
