Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electrolytic cell optimization, and particularly relates to an AEM electrolytic cell device based on flow channel optimization. BACKGROUND

[0002] AEM electrolytic cell: an anion exchange membrane electrolytic cell, membrane electrode type: using pure water or low-concentration alkaline electrolyte, water molecules are electro-reduced into hydrogen gas at the cathode of the membrane electrode, and hydroxyl is generated, then the hydroxyl is transmitted to the anode through the AEM membrane, and finally oxidized into oxygen at the anode;

[0003] Analysis of the actual working condition of the AEM electrolytic cell in the high-concentration dust environment:

[0004] Dust particles exist in the deposition phenomenon between the bipolar plate, the cathode electrode, the anode electrode, the gasket and the diaphragm, and then cause the local flow rate of the electrolyte flow field to decrease or even stop, in addition, the downstream of the blocked area will form a vortex or dead volume, until the electrolyte is retained, the local hydroxyl concentration gradient is unbalanced, and the ion conduction efficiency is affected;

[0005] The dust is adsorbed on the surface of the foregoing components or in the overlapping gap, which hinders the contact between the electrolyte and the catalyst layer, and causes the mass transfer resistance of the reactant (H2O) and the product (H2, O2) to increase; at the same time, the dust is deposited on the membrane surface to form a "pollution layer", which increases the diffusion path of ions through the membrane, and causes the concentration polarization voltage to rise;

[0006] When the high-concentration dust flows at a high speed with the electrolyte, erosion and wear are caused on the flow field plate groove or the surface of the current collector, which causes the roughness of the flow channel to increase, the pressure drop to rise, and hard dust particles to scratch the membrane surface under the action of the flow field pressure, thereby forming micro-cracks or holes, and causing the electrolyte to flow between the cathode and the anode.

[0038] The dust cleaning method of the outer wall of the electrolytic cell electrode assembly adopts the AEM electrolytic cell device based on the flow channel optimization for cleaning, and the specific steps are as follows:

[0039] S1: first, the connecting rod is pushed through the one-side fitting seat, the corresponding position ring is rotated by a specified angle, at this time, the support is guided and limited in the slot, the movable telescopic column drives the tool holder to move to the dial axis direction as a whole, until the sponge pad is distributed opposite to the first electrode assembly in the same line during the process;

[0040] S2: then, the sponge pad is controlled to move to the dial axis direction through the electric telescopic rod, until the sponge pad contacts the electrode assembly, before this, the external cleaning liquid can be sprayed to the working surface of the sponge pad in the form of atomization through the water hole in the water tank through the water valve, and the quantitative and uniform spraying of the working surface of the sponge pad is realized by changing the aperture size of the water hole in a gradient manner;

[0041] During the process, the continuous operation of the sponge pad in different areas is changed by intermittent rotation of the rotating wheel, and the dust particles on the working surface of the sponge pad after adsorption are dried and separated in the cleaning chamber through the heating of the electric heating sheet and the interaction between the flexible roller brush and the working surface of the sponge pad, and the dust particles are pumped into the dust cylinder through the air pipe and the guide pipe, so that the adsorption between the sponge pad and the dust particles on the surface of the electrode assembly is ensured, and the pre-treatment of removing the dust on the surface of the electrode assembly is completed;

[0042] S3: finally, the shovel plate moving synchronously with the dial is used to interact with the dust on the surface of the electrode assembly during movement, and the dust between the end surface of the shovel plate and the area between the shovel plate and the vertical fixed rod is guided and adsorbed through the double-open bin, so as to reduce the accumulation of dust on the surface of the electrode assembly;

[0043] In addition, during specific implementation, the interaction degree between the shovel plate and the surface of the electrode assembly is adjusted synchronously through the fine adjustment of the rotation angle of the ring, so that the shovel plate sequentially and gradually cleans the dust deposited on the outer surface of the electrode assembly, the friction between the dust particles and the shovel plate is uniformized during single cleaning, the excessive rigid contact between the dust particles and the electrode assembly is avoided, the scratches are reduced, and the service life of the electrode assembly is improved.

[0044] The present application has the following beneficial effects:

[0045] 1. The present application changes the contact integrity between the dust particles on the external end face of the electrode assembly and the sponge pad in different positions by the rotating wheel, and through the heating of the electric heating sheet and the equivalent interaction between the flexible roller brush and the working surface of the sponge pad, the dust particles on the surface of the sponge pad in the adsorption state are processed to dry and separate inside the cleaning chamber, ensuring the adsorption of the sponge pad in contact with the external surface of the electrode assembly at a single time, and through the atomization of the cleaning liquid on the working surface of the sponge pad, the interfacial tension between the dust cylinder electrode assembly is reduced, the hydrophobic dust or charged dust is accelerated to separate from the surface, and the "micro-infiltration" of the sponge pad can dissolve and infiltrate the dust particles, avoiding secondary dust caused by dry cleaning, which helps to protect the surface of the electrode assembly and reduce the probability of rigid contact scratches between the dust and the surface of the electrode assembly.

[0046] 2. The present application promotes the relative motion between the shovel plate and the dust on the surface of the electrode through the consistency of the motion between the shovel plate and the graduated disc, and through the expansion of the solid contact area of the dust groove, the interception and guiding effect of the shovel plate on the dust particles is strengthened, ensuring that the dust flows along the shovel plate arc surface to the double-opening bin area, and finally through the suction effect of the air pipe, the dust on the shovel plate arc surface and the dust between the double-opening bin and the vertical fixed rod are pumped to the dust cylinder through the duct, further improving the collection degree of the dust on the surface of the electrode assembly, reducing the risk of dust filling and penetrating into the overlapping gap of the electrode assembly, and improving the stability of the flow field between the electrode assemblies.

[0072] Referring to Figure 3 and Figure 6 It can be seen that the adjusting unit 4 comprises: an annular guide rail 41 which is symmetrically rotationally fitted on the outer walls of both sides of the dial 1, and the inner wall diameter of the annular guide rail 41 is greater than the inner diameter of the dial 1; a fitting seat 42 which is slidingly and detachably fitted on the end faces of both sides of the dial 1; a connecting rod 43 which is circumferentially and detachably fitted on the end face of one side of the annular guide rail 41 close to the dial 1, and the connecting rod 43 is slidingly and detachably fitted with the dial 1 at the same time, and is detachably fitted with the fitting seat 42; a ring 44 which is detachably fitted on the end face of one side of the annular guide rail 41 away from the dial 1; a slot 45 which is circumferentially and uniformly provided on the outer wall of the ring 44, and is slidingly and detachably fitted with the support 316; an angle steel frame 46 which is symmetrically and detachably fitted on the outer wall of the dial 1, and is slidingly and detachably fitted between the angle steel frame 46 and the strip rail 14.

[0073] The adhesion unit 2 and the gradient cleaning unit 3 reciprocate along the axis of the vertical fixing rod 18, and the adhesion unit 2 and the gradient cleaning unit 3 move simply:

[0074] Firstly, the angle steel frame 46 drives the dial 1 to move along the vertical fixed rod 18 axis under the support and guidance of the rail 14, and in the process, the base shaft 15 and the bracket 16 assist the case 11 to move to the angle steel frame 46 to provide a stable working environment, and ensure the same frequency between the dial 1 and the electronic components during the movement of the dial 1, and in the specific implementation, the angle steel frame 46 can be driven to move by the electric sliding block;

[0075] It is hereby stated that in the specific implementation, the adhesion unit 2, the gradient cleaning unit 3 and the cleaning unit in the present application can be symmetrically distributed by adding the dial 1, so as to realize the consistency of the work on the surface of the electrode assembly 19 under the reciprocating motion state of the adhesion unit 2 and the gradient cleaning unit 3;

[0076] Then, through the interaction between the fitting seat 42 and the connecting rod 43, the connecting rod 43 is driven to rotate a certain angle under the guidance of the dial 1, and in the specific implementation, the fitting seat 42 can be driven to move by the electric sliding block;

[0077] Finally, through the rotation of the mouth ring 44, the interaction (see the subsequent introduction) between the mouth groove 45 and the internal components of the adhesion unit 2 or the gradient cleaning unit 3 promotes the whole adhesion unit 2 and the gradient cleaning unit 3 to move radially along the dial 1 to the designated position;

[0079] The angle bar 13: on the one hand, it increases the heat dissipation path inside the case 11, optimizes the heat dissipation mode, helps to suppress the thermal degradation and expansion of the membrane, and at the same time, to a certain extent, can prevent electrode corrosion and active site inactivation; on the other hand, it can provide a stable installation point for external connecting components, improve the transportation or operation stability, and ensure the safety of the equipment.

[0080] Referring to Figure 7 , Figure 8 and Figure 9It can be known that the adhesion unit 2 comprises: a top arc seat 21, which is uniformly and circumferentially clamped and installed on one side of the inner wall of the dial 1; two movable telescopic columns 22, which are symmetrically clamped and installed on the end face of the top arc seat 21 close to the axis of the dial 1; a tool holder 23, which is clamped and installed on the ends of the two movable telescopic columns 22 away from the top arc seat 21; a guard plate 24, which is clamped and installed on the outer walls of the vertical sections of the tool holder 23; an electric telescopic rod 25, which is symmetrically clamped and installed on the end face of the horizontal section of the tool holder 23 away from the top arc seat 21; an end plate 26, which is clamped and installed on the end of the electric telescopic rod 25 away from the top arc seat 21; an ear seat 27, which is clamped and installed on the end face of the end plate 26 away from the top arc seat 21; a rotating wheel 28, which is rotationally fitted between the two ear seats 27; and four groups of support plates 29, which are circumferentially clamped and installed on the outer wall of the rotating wheel 28.

[0081] With reference to Figure 8 And Figure 10 It can be known that the end face of the support plate 29 away from the axis of the rotating wheel 28 is clamped and installed with a sponge pad 211, the middle position of the end face of the horizontal section of the tool holder 23 away from the top arc seat 21 is clamped and installed with a cleaning chamber 212, the opposite inner walls of the cleaning chamber 212 are clamped and installed with electric heating sheets 213, the opposite inner walls of the cleaning chamber 212 are rotationally fitted with flexible rolling brushes 214, the outer walls of one side of the cleaning chamber 212 are symmetrically inserted and installed with air pipes 215, one side of the horizontal section of the tool holder 23 is clamped and installed with a dust cylinder 216, and the outer walls of one side of the dust cylinder 216 are symmetrically inserted and installed with guide pipes 217.

[0082] With reference to Figure 8 And Figure 9 It can be known that the inner wall of one side of the guard plate 24 is clamped and installed with a water tank 221, the length and width of the water tank 221 are greater than those of the sponge pad 211, the cross-sectional shape of the water tank 221 is a right trapezoid, the end face of one side of the water tank 221 close to the sponge pad 211 is uniformly provided with water holes 222, the diameter of the water holes 222 decreases along the gravity direction, and the end face of one side of the water tank 221 away from the sponge pad 211 is inserted and installed with a water valve 223 penetrating through the guard plate 24; the side of the sponge pad 211 close to the axis of the dial 1 is an arc surface, and the inner diameter of the arc surface is equal to the outer diameter of the electrode assembly 19; and the bristles of the flexible rolling brush 214 are in contact with one end of the sponge pad 211.

[0083] It is hereby stated that the width of the sponge pad 211 is at least equal to the vertical distance between the opposite outer walls of the guard plate 24, and the vertical height difference between the sponge pad 211 and the guard plate 24 along the radial direction of the dial 1 is at least equal to the difference between the outer diameters of the electrode assembly 19 and the electrolytic cell frame 17.

[0084] The adsorption process of the sponge pad 211 on the dust on the surface of the electrode assembly 19 (the area between adjacent vertical fixed rods 18):

[0085] Firstly, the sponge pad 211 is tangent to the intersection surface between the electrode assembly 19 and the electrolytic cell frame 17 at the beginning of the movement, and the adhesive unit 2 is attached to the front end of the gradient cleaning unit 3 in the direction of movement.

[0086] In specific implementation, the aforementioned angle steel frame 46 can drive the dial plate 1 to move the adhesive unit 2 along the vertical rod 18 axis under the support and guidance of the strip rail 14, so as to adjust the tangent of the intersection surface between the one side end surface of the sponge pad 211, the electrode assembly 19 and the electrolytic cell frame 17.

[0087] Then, the mouth ring 44 rotates by a specified angle, and the support 316 is extruded under the limiting action of the mouth groove 45 (the engagement degree between the mouth groove 45 and the support 316 is the maximum distance (extension or contraction) that the tool holder 23 can move, and at this time the sponge pad 211 is not in contact with the surface of the electrode assembly 19), which synchronously drives the tool holder 23 to move towards the axis of the dial plate 1 (and when the tool holder 23 moves towards the axis of the dial plate 1, the rotation direction of the mouth ring 44 is positive), and in this process, the sponge pad 211 is limited between adjacent vertical rods 18 by the top arc seat 21, and further stable support and guidance is provided to the movement of the tool holder 23 by the movable telescopic column 22.

[0088] Finally, the ear seat 27 is synchronously driven to move towards the axis of the dial plate 1 by the end plate 26 under the extension control of the electric telescopic rod 25, until the sponge pad 211 is in contact with the surface of the electrode assembly 19 (before this, the water valve 223 and the cleaning liquid are connected by an external hose, and then the cleaning liquid is stably pumped into the water tank 221 by an external water pump, and then the spray cleaning liquid is sprayed to the working surface of the sponge pad 211 in the current area through the water hole 222, and the relative angle between the slope of the water tank 221 and the sponge pad 211 is changed to linearly adjust the diameter of the water hole 222, so as to reduce the uniformity of different areas under the action of centrifugal force and gravity when the sponge pad 211 rotates, and the excessive accumulation of cleaning liquid in the sponge pad 211 is reduced by the spray cleaning liquid, and the penetration of cleaning liquid into the overlapping gap between the electrode assembly 19 is reduced (in specific implementation, the electrolytic reaction of the electrolytic cell can continuously emit heat to the outside, which can implement thermal decomposition of the aforementioned cleaning liquid in the sponge pad 211));

[0089] At the same time, the position of the sponge pad 211 can be alternately changed by intermittent rotation of the rotating wheel 28, and when the sponge pad 211 is opposite to the cleaning chamber 212 after the adsorption operation is completed, the rotating wheel 28 is driven by the electric telescopic rod 25 to move reversely to the top arc seat 21 as a whole until the sponge pad 211 is in the same degree of interaction with the flexible roller brush 214 (the vertical distance between any point on the arc surface of the sponge pad 211 and the corresponding bristles of the flexible roller brush 214 is equal, so as to avoid different degrees of interaction and excessive damage to the bristles of the flexible roller brush 214 and the sponge pad 211), and the sponge pad 211 and the flexible roller brush 214 inside the cleaning chamber 212 are subjected to drying treatment by the heating effect of the electric heating sheet 213 (in specific implementation, a sealing ring can be additionally arranged at the opening end of the cleaning chamber 212 to prevent dry dust particles from splashing outside), and in specific implementation, the rotating wheel 28 or the flexible roller brush 214 can be driven to rotate by an external motor or a micro motor;

[0090] The wind pipe 215 and the conduit 217 are connected by an external hose, and the dust inside the cleaning chamber 212 in the relative motion state is pumped to the inside of the dust cylinder 216 by an external centrifugal fan, so as to realize the self-cleaning process of the surface of the sponge pad 211 and ensure the adsorption effectiveness of the working surface of the sponge pad 211 at the moment;

[0091] The working surface of the sponge pad 211 in the wet state can effectively avoid mechanical damage and inhibit electrochemical pollution residues (chelating agents (such as EDTA) or corrosion inhibitors in the cleaning liquid can be combined with harmful ions and removed synchronously with sponge wiping to avoid secondary pollution).

[0092] Referring to Figure 7 , Figure 11 and Figure 12 , the gradient cleaning unit 3 comprises: a wall plate 31, which is peripherally clamped and installed in the space on the other side of the inner wall of the bezel 1 and corresponds to the top arc seat 21 one by one; in addition, the wall plate 31 has the same appearance as the top arc seat 21; a telescopic rod 32, which is symmetrically clamped and installed on the end face of the wall plate 31 close to the axis of the bezel 1; a face plate 33, which is one in number and is clamped and installed at one end of the telescopic rod 32 away from the wall plate 31; a mouth frame 34, which is clamped and installed on the outer wall of the face plate 33; a stand column 35, which is slidingly clamped and cooperatively installed between the horizontal section of the mouth frame 34 and the face plate 33; a reset spring 36, which is sleeved and installed on the outer wall of the stand column 35 and located between the horizontal section of the mouth frame 34 and the face plate 33; and a shovel plate 37, which is symmetrically clamped and installed at one end of the two stand columns 35 away from the wall plate 31;

[0093] Referring to Figure 5 , Figure 7 and Figure 11It can be known that the dust groove 311 is arranged on the end surface of the shovel plate 37 away from the axis of the stand 35, and the number of the dust groove 311 is at least two, the double-opening bin 312 is connected to the two ends of the shovel plate 37, the angle valve 313 is connected to the end surface of the double-opening bin 312 close to the wall plate 31, the dust-reducing cylinder 314 is connected to one end of the panel 33, and the dust-reducing cylinder 314 has the same appearance as the dust cylinder 216, the angle pipe 315 is connected to the outer wall of the dust-reducing cylinder 314 in a symmetrical manner, and the vertical section of one side of the opening frame 34 and the tool frame 23 is connected to the support 316.

[0094] The longitudinal section of the shovel plate 37 is in the shape of an open ring 44, and the number of the vertical fixing rods 18 is equally divided into the open ring 44, the position between the shovel plate 37 and the double-opening bin 312 is tangent, in addition, the cross section of the shovel plate 37 is isosceles trapezoidal, and the shovel plate 37 is subjected to a parting process.

[0095] It is hereby stated that the height of the shovel plate 37 is at least equal to the difference between the outer diameter of the electrode assembly 19 and the electrolytic cell frame 17, and the width between the symmetrically distributed shovel plates 37 is at least equal to the width of the opening frame 34.

[0096] The shovel plate 37 complements the cleaning process of the surface of the electrode assembly 19 (compared to the sponge pad 211).

[0097] Similarly, the motion cooperation between the angle steel frame 46 and the rail 14 can promote the dial 1 to control the motion of the shovel plate 37 synchronously, until the end surface of the shovel plate 37 away from the adhesion unit 2 is tangent to the intersection surface of the electrode assembly 19 and the electrolytic cell frame 17.

[0098] By rotating the mouth ring 44, the support 316 is limited in the mouth groove 45, the opening frame 34 is controlled to be supported and guided by the telescopic rod 32, the stand 35 is driven to move the shovel plate 37 to the direction of the electrode assembly 19, and in specific implementation, the relative distance between the shovel plate 37 and the surface of the electrode assembly 19 can be adjusted by the rotation angle of the mouth ring 44 (the interaction between the shovel plate 37 and the electrode assembly 19 is changed by the elastic recovery of the reset spring 36), so as to control the equal cutting of the dust layer in the single shovel plate 37 motion process, and realize the gradual scraping and shearing.

[0099] On the one hand, the dust accumulation is avoided (the segmented shovel plate 37 can further reduce the dust accumulation), and the probability of excessive rigid contact between the dust and the surface of the shovel plate 37 and the electrode assembly 19 is reduced; on the other hand, the sponge pad 211 can be dissolved to adhere to a layer of dust, and the shovel plate 37 can scrape a layer, so as to ensure the scraping precision and improve the softness of the contact between the shovel plate 37 and the electrode assembly 19.

[0100] Double opening bin 312, dust groove 311, angle valve 313, angle pipe 315 and dust falling cylinder 314: connect angle valve 313 and angle pipe 315 through external hose, and through external centrifugal fan, so that the opening end of double opening bin 312 forms a certain negative pressure area with the external space, so that the dust on the arc surface of shovel plate 37 and the dead angle dust between double opening bin 312 (symmetrical) and vertical fixed rod 18 continuously flow to the inside of dust falling cylinder 314 under the action of negative pressure;

[0101] By effectively unifying the consistency of the arc surface between double opening bin 312 and shovel plate 37, cooperating with dust groove 311 to strengthen the drainage and guide of the dust in the passing process, optimizing the flow field of the dust flowing to double opening bin 312, and reducing the retention amount of the dust on the surface of electrode assembly 19 (for details, refer to).

[0102] The working principle of the AEM electrolytic cell device based on flow channel optimization provided by the application is as follows: first step: first push connecting rod 43 through one side of embedded seat 42, so that corresponding position ring 44 rotates by a specified angle, at this time, under the guidance and limiting action of slot 45, control movable telescopic column 22 to drive tool holder 23 to move to the axis direction of dial 1 as a whole until sponge pad 211 is distributed opposite to the “first” electrode assembly 19 in the passing process;

[0103] Second step: then control sponge pad 211 to move to the axis direction of dial 1 through electric telescopic rod 25 until sponge pad 211 is in contact with electrode assembly 19, before this, external cleaning liquid can be sprayed to the working surface of sponge pad 211 in the form of atomization through water hole 222 in water bin 221 through water valve 223, and the quantitative and uniform spraying of the working surface of sponge pad 211 is realized by changing the aperture size of water hole 222 in a gradient manner;

[0104] In this process, the continuous operation of sponge pad 211 in different areas is changed by intermittent rotation of rotating wheel 28, and the dust particles existing on the working surface of sponge pad 211 after adsorption are dried and separated in cleaning chamber 212 through the heating of electric heating sheet 213 and the interaction between flexible roller brush 214 and the working surface of sponge pad 211, and are pumped into dust cylinder 216 through air pipe 215 and conduit 217, so as to ensure the adsorption between sponge pad 211 and the dust particles on the surface of electrode assembly 19 in a single time, and complete the pre-treatment of removing the dust on the surface of electrode assembly 19;

[0105] Third step: finally, shovel plate 37 moves synchronously with dial 1, and continuously interacts with the dust on the surface of electrode assembly 19 during movement, and at the same time, double opening bin 312 guides and adsorbs the dust between the end surface of shovel plate 37 and the region between shovel plate 37 and vertical fixed rod 18, so as to reduce the accumulation of dust on the surface of electrode assembly 19;

[0106] In addition, in the implementation, the interaction between the shovel plate 37 and the surface of the electrode assembly 19 is adjusted synchronously by fine-tuning the rotation angle of the mouth ring 44, so that the shovel plate 37 sequentially and gradually cleans the dust layer deposited on the outer surface of the electrode assembly 19, the friction between the dust particles and the shovel plate 37 is uniformed in a single cleaning, the excessive rigid contact between the dust particles and the electrode assembly 19 is avoided, the scratches are reduced, and the service life of the electrode assembly 19 is improved.
