Example 1
In order to solve the problems of excessively complex structure, excessive energy loss and unbalanced power balance of the electrolytic device in the prior art, referring to fig. 1 to 5, in an embodiment of the present invention, there is provided a motor-powered electrolytic device, which includes a transmission part 03 connected to a rotary motor 01, an electrolytic unit and a dc interface 02; the electrolysis unit comprises a rotatable magnetic circuit 11 and an annular electrolysis cell 12;
electrolyte is injected into the annular electrolytic cell 12; the annular electrolytic cell 12 includes a cell membrane 121; the electrolytic cell diaphragm 121 is used for dividing the electrolyte into a cathode chamber and an anode chamber; the cathode chamber and the anode chamber are respectively provided with a cathode plate 122 and an anode plate 123; the cathode plate 122 and the anode plate 123 lead out a direct current interface 02;
the rotatable magnetic circuit 11 includes a rotation shaft 111 passing through an annular ring of the annular electrolytic cell 12 (i.e., the annular ring of the annular electrolytic cell 12), and one or more pairs of pole pieces (e.g., a first pole piece 112 and a second pole piece 113) located on both sides of the electrolytic cell diaphragm 121 and perpendicular to the electrolytic cell diaphragm 121, respectively;
one end of the transmission part 03 is in transmission connection with the rotary prime mover 01, and the other end of the transmission part 03 is in transmission connection with the rotating shaft 111 and is used for driving the rotating shaft 11;
the driven rotating shaft 11 can drive the pole shoe pairs to rotate on two sides of the annular electrolytic cell 12; the rotation causes an induced potential and an induced current to be generated between the electrolytes on both sides of the cell membrane 121;
the direct current interface 02 is connected to the grid via an inverter-rectifier for outputting electrical energy to the grid or for receiving electrical energy from the grid according to a first predetermined rule.
In the embodiment of the invention, electrolysis is realized by adopting a method of generating induced current by driving a magnet to rotate by a rotary prime motor 01; the rotary prime mover 01 is affected by natural conditions, and the energy supply of the rotary prime mover is easy to fluctuate, so that the electric energy induced by the annular electrolytic cell 12 also has larger fluctuation, and accordingly, the stability of the electrolytic process of the rotary prime mover is negatively affected. For example, taking the rotary prime mover 01 as a wind motor as an example, the output of the wind motor fluctuates along with the fluctuation of the magnitude of the natural wind, and for the annular electrolytic cell 12, a relatively balanced power supply is beneficial to the normal operation of the electrolytic process.
For this purpose, in the exemplary embodiment of the invention, a direct-current interface 02 is also provided for connection to the grid and 05 via the inverter-rectifier 04 in order to output electrical energy to the grid or to receive electrical energy from the grid. The basic principle is that when the output force of a rotary prime motor 01 such as a wind turbine or a hydraulic engine is overlarge (larger than the maximum reasonable requirement of an electrolysis unit), the surplus partial electric energy is output through a direct current interface 02, and the direct current is converted into alternating current matched with a power grid 05 through an inverter-rectifier 04 to realize the power supply to the power grid 05, so that the electric energy is saved on one hand, and the electrolysis unit is prevented from being impacted by overlarge current on the other hand; in addition, when the energy supply of the rotary prime motor 01 is too small to meet the minimum requirement of the electrolysis unit, the alternating current of the power grid 05 is converted into the direct current available by the electrolysis unit through the inverter-rectifier 04, so that the energy supply gap of the rotary prime motor 01 is supplemented, and the requirement of the normal electrolysis process of the electrolysis unit is ensured.
In addition, similar to the DC interface 02 being connected to the grid through an inverter-rectifier, as shown in fig. 2, in the embodiment of the present invention, the DC interface 02 may be further electrically connected to the energy storage device 07 (e.g., a battery) through the DC/DC converter 06, for outputting electric energy to the energy storage device 07 or receiving electric energy from the energy storage device 07. Specifically, it may be: when the output force of the rotary prime motor 01 such as a wind turbine or a water conservancy engine is too large (larger than the maximum reasonable requirement of the electrolysis unit), the surplus partial electric energy is output through the direct current interface 02, and the direct current is converted into the direct current matched with the energy storage device 07 through the DC/DC converter 06 to realize the energy supply to the energy storage device 07, so that the electric energy is saved on one hand, and the electrolysis unit can be prevented from being impacted by the excessive current on the other hand; in addition, when the energy supply of the rotary prime motor 01 is too small to meet the minimum requirement of the electrolysis unit, the DC/DC converter 06 converts the DC of the energy storage device 07 into the available DC of the electrolysis unit, thereby supplementing the energy supply gap of the rotary prime motor 01 and ensuring the requirement of the normal electrolysis process of the electrolysis unit.
Preferably, in order to achieve automatic power balance of the cell power supply, as shown in fig. 2 or 3, in an embodiment of the present invention, a processing unit (not shown in the drawings) and a monitoring unit 08 may be further included;
the monitoring unit 08 (such as a voltmeter) is used for collecting voltage data between the cathode plate 122 and the anode plate 123 in real time; the processing unit is configured to generate a control instruction of the power transmission direction of the inverter-rectifier 08 according to a first preset rule or generate a control instruction of the power transmission direction of the DC/DC converter 06 according to a second preset rule by using the voltage data as a parameter.
In practical applications, the first preset rule and the second preset rule may respectively include a set threshold range (the threshold range may be determined according to the maximum reasonable requirement and the minimum requirement of the electrolysis unit), so as to generate a control instruction to output the surplus electric energy of the electrolysis unit through the dc interface 02 after the voltage between the cathode plate 122 and the anode plate 123 exceeds the corresponding threshold range, or input the electric energy to the electrolysis unit through the dc interface 02, so as to realize the power balance of the electrolysis unit.
It should be noted that, in the embodiment of the present invention, the inverter-rectifier or the DC/DC converter should have a bidirectional power function.
As shown in fig. 1, in the embodiment of the present invention, an induced potential and an induced current are directly generated between electrolytes on both sides of an electrolytic cell membrane 121, so that the electrolytes are electrolyzed; the working principle of the embodiment of the invention is that when the rotary prime mover 01 outputs mechanical energy, the transmission part 13 can drive the rotating shaft of the rotary magnetic circuit 11 to rotate, and at the moment, the rotary magnetic circuit 11 drives the two pole shoes respectively adjacent to the cathode chamber and the anode chamber of the annular electrolytic cell 12 to rotate; since the annular electrolytic cell 12 is stationary, when the pole shoe pair rotates, the rotating magnetic field between the pole shoe pair will be cut by the electrolyte in the annular electrolytic cell 12, thereby generating induced potential and induced current in the electrolyte, and causing electrochemical reaction of the electrolyte.
In practical use, as shown in fig. 4, the cross section of the annular electrolytic cell 12 may be rectangular; in addition, the cross section of the annular electrolytic cell 12 may be annular.
In the embodiment of the present invention, the electrolyte in the annular electrolytic cell 12 needs to be partitioned into a cathode chamber and an anode chamber by the cell membrane 121; the direction of the electrolyte membrane 121 needs to be adapted to two pole shoes of the pole shoe pair in the rotatable magnetic circuit 11, that is, after the electrolyte membrane 121 separates the annular electrolyte tank 12 into an anode chamber and a cathode chamber, two opposite pole shoes of the pole shoe pair are respectively positioned at one side of the anode chamber and one side of the cathode chamber, so that when the pole shoe pair rotates, the purpose that magnetic force lines of a magnetic field between the pole shoe pair can be cut by electrolyte in the annular electrolyte tank 12 is achieved, specifically:
as shown in FIG. 5, when the pole shoe pair rotates, the electrolyte in the annular electrolytic cell 12 moves relative to the magnetic field (magnetic induction B) between the two pole shoes, the relative velocity is v, and perpendicular to the magnetic lines, and the electrolyte is conductive, so that an induced potential E is generated in the electrolyte i ：
In induced electric field E i Under the action of the electrolyte, cations migrate to the cathode direction and anions migrate to the anode direction, resulting inThe current density J is:
J＝γE i
the electrolyte in the annular electrolytic cell 12 undergoes electrolytic reactions at the cathode and the anode, respectively. Unlike the prior art, which relies on a dc power supply to be applied externally, the electric field in the embodiments of the present invention occurs in the electrolyte.
It should be noted that, the magnet in the embodiment of the present invention may be a permanent magnet or an electromagnet; wherein the permanent magnets are preferably high energy storage permanent magnets.
Further, as shown in fig. 6, the inner cavity of the annular electrolytic cell 12 in the embodiment of the present invention may further include a plurality of mutually independent subchambers 201 (i.e., a plurality of electrolytic cells or groups of electrolytic cells are formed by the plurality of subchambers 201); each subchamber 201 is provided with a cell membrane 121, a cathode plate 122 and an anode plate 123; so that each subchamber can be used individually as a subchamber. It should be noted that, the number and the size of the sub-cavities in the embodiments of the present invention may be set by those skilled in the art according to needs, and are not limited herein.
Further, in the embodiment of the present invention, the transmission component further includes a speed change mechanism (not shown in the figure); the rotating speed change mechanism is arranged between the rotating prime motor and the rotating shaft and is used for controlling the rotating speed of the rotating shaft.
In summary, in the embodiment of the invention, in the electrolysis device powered by the prime mover, the electrolysis unit comprises the rotatable magnetic circuit and the annular electrolysis cell, and the rotatable magnetic circuit can generate induced potential and induced current in the electrolyte between the cathode chamber and the anode chamber of the annular electrolysis cell when rotating, so that after the transmission component connected with the rotary prime mover in a transmission way is arranged, the mechanical energy of the rotary prime mover can be used for driving the generation of the induced potential and the induced current for electrolyzing the electrolyte in the electrolyte, and the mechanical energy is directly converted into chemical energy, thereby realizing electrolysis.
The electrolytic cell of the invention does not need to be provided with a direct current power supply, can directly convert the mechanical energy of the rotary prime motor into electrolytic energy, and reduces the links of energy conversion, thereby effectively simplifying the structure of the electrolytic cell and reducing the energy loss caused by energy conversion.
In addition, since the embodiment of the invention is also provided with the direct current interface, the direct current interface can be connected with an external power grid or an energy storage device so as to realize that when the energy supply of the rotary prime motor fluctuates, the surplus electric energy is transmitted to the external power grid or the energy storage device according to the electric energy demand of the electrolysis unit, or the power balance of the electrolysis unit is realized through the auxiliary energy supply of the external power grid or the energy storage device when the energy supply of the rotary prime motor is insufficient, thereby effectively improving the stability of the electrolysis process of the electrolysis device.
Example two
On the basis of the first embodiment, preferably, in the embodiment of the present invention, as shown in fig. 1, the cell membrane 121 may be provided in parallel with the axial direction of the rotation shaft 111, so that the cell may be divided into an anode chamber on one side of the annular inner wall of the annular electrolytic cell 12 and a cathode chamber on one side of the annular outer wall of the annular electrolytic cell 12 (as shown in fig. 1); further, depending on the rotation direction of the rotatable magnetic circuit 11, the electrolytic cell may be divided into a cathode chamber on one side of the inner ring wall of the annular electrolytic cell 12 and an anode chamber on one side of the outer ring wall of the annular electrolytic cell 12; at this time, in order to fit the pole shoe with the cell membrane 121, the structure of the rotatable magnetic circuit 11 may be set as follows:
the rotating shaft 111 as a magnet passes through an annular hole surrounded by the annular electrolytic cell 12, and the upper and lower ends of the rotating shaft 111 are respectively provided with one or more pairs of pole shoes (e.g., disk-shaped first pole shoe 112 and second pole shoe 113); an annular electrolytic cell 12 is located between the pole shoe pairs. Preferably, the outer edges of the disc-shaped pole pieces are adapted to the outer edges of the annular electrolytic cell 12.
The magnetic field B applied by the rotatable magnetic circuit 11 is perpendicular to the annular electrolytic cell 12, and its rotation can achieve a magnetic field rotation. The magnetic induction intensity of the rotatable magnetic circuit 11 in the annular electrolytic cell 12 is B, and the rotation linear velocity is v; since the electrolyte is relatively stationary and the magnetic field is relatively moving, the v direction in the induced electric field calculation formula is opposite to the direction of magnetic field movement. Taking fig. 1 as an example, the induced electric field is directed from the inner ring to the outer ring, so that one side of the inner ring wall of the annular electrolytic cell 12 is the anode chamber of the electrolytic cell, and one side of the outer ring wall is the cathode chamber of the electrolytic cell; that is, in the annular electrolytic cell 12, as shown in fig. 5, an anode reaction occurs on the inner side and a cathode reaction occurs on the outer side.
It should be noted that, in the embodiment of the present invention, specific implementation and technical effects of the power-supplied electrolysis system of the prime mover may refer to the power-supplied electrolysis device of the prime mover corresponding to the first embodiment, and will not be described herein.

On the basis of the first embodiment, preferably, in the embodiment of the present invention, as shown in fig. 7, the cell diaphragm 121 may be provided perpendicularly to the axial direction of the rotation shaft 111, so that the cell may be divided into an anode chamber on the side of the upper end of the annular cell 12 and a cathode chamber on the side of the lower end of the annular cell 12; further, depending on the rotation direction of the rotatable magnetic circuit 11, the electrolytic cell may be divided into a cathode chamber on the side of the upper end of the annular electrolytic cell 12 and an anode chamber on the side of the lower end of the annular electrolytic cell 12; at this time, in order to adapt the pole shoe pair to the cell membrane 121, the structure of the rotatable magnetic circuit 11 may be set as follows:
the rotating shaft 111 as one pole shoe of the pair of pole shoes of the rotatable magnetic circuit passes through a circular hole surrounded by the annular electrolytic cell 12 and an annular magnet is sleeved at the upper end of the rotating shaft; the outer edge of the annular magnet is sleeved with a pipe-shaped other pole shoe; an annular electrolytic cell 12 is located between the two pole pieces.
Unlike the second embodiment, in the embodiment of the present invention, when the rotatable magnetic circuit rotates counterclockwise, the direction of magnetic force lines is horizontally inward, the direction of an induced electric field generated in the electrolyte (for example, electrolyzed water) is from top to bottom, the upper side of the electrolytic cell is an anode chamber, and the lower side is a cathode chamber; the intermediate annular electrolyte membrane 121 isolates the generated gas and establishes an internal electric field.
Example IV
In another aspect of the embodiments of the present invention, there is also provided a prime mover powered electrolysis system, as shown in fig. 2 or 3, comprising a rotary prime mover and the prime mover powered electrolysis device described in the above embodiments;
in the embodiment of the invention, the electrolysis device is directly linked with the rotary prime motor 01, so that induced potential and induced current are directly generated between the electrolyte at two sides of the electrolytic cell diaphragm 121, and the electrolyte is electrolyzed; the working principle of the embodiment of the invention is that when the rotary prime mover 01 outputs mechanical energy, the transmission part 13 can drive the rotating shaft of the rotary magnetic circuit 11 to rotate, and at the moment, the rotatable magnetic circuit 11 drives the pole shoe pairs respectively adjacent to the cathode chamber and the anode chamber of the annular electrolytic cell 12 to rotate; since the annular electrolytic cell 12 is stationary, when the pole shoe pair rotates, the rotating magnetic field between the pole shoe pair will be cut by the electrolyte in the annular electrolytic cell 12, thereby generating induced potential and induced current in the electrolyte, and causing electrochemical reaction of the electrolyte.
In the embodiment of the invention, electrolysis is realized by adopting a method of generating induced current by driving a magnet to rotate by a rotary prime motor 01; the rotary prime mover 01 is affected by natural conditions, and the energy supply of the rotary prime mover is easy to fluctuate, so that the electric energy induced by the annular electrolytic cell 12 also has larger fluctuation, and accordingly, the stability of the electrolytic process of the rotary prime mover is negatively affected. For this purpose, in the embodiment of the invention, a direct-current interface 02 is also provided for connection to the grid and 05 via the inverter-rectifier 04 in order to achieve the output of electrical energy to the grid or the reception of electrical energy from the grid 05. The basic principle is that when the output force of a rotary prime motor 01 such as a wind turbine or a hydraulic engine is overlarge (larger than the maximum reasonable requirement of an electrolysis unit), the surplus partial electric energy is output through a direct current interface 02, and the direct current is converted into alternating current matched with a power grid 05 through an inverter-rectifier 04 to realize the power supply to the power grid 05, so that the electric energy is saved on one hand, and the electrolysis unit is prevented from being impacted by overlarge current on the other hand; in addition, when the energy supply of the rotary prime motor 01 is too small to meet the minimum requirement of the electrolysis unit, the alternating current of the power grid 05 is converted into the direct current available by the electrolysis unit through the inverter-rectifier 04, so that the energy supply gap of the rotary prime motor 01 is supplemented, and the requirement of the normal electrolysis process of the electrolysis unit is ensured.
In addition, in embodiments of the present invention, the DC interface 02 may be electrically connected to the energy storage device 07 (e.g., a battery) via the DC/DC converter 06 for outputting electrical energy to the energy storage device 07 or receiving electrical energy from the energy storage device 07, similar to the connection to the grid 05 via the DC interface 02 and the grid-connected via the inverter-rectifier 04. Specifically, it may be: when the output force of the rotary prime motor 01 such as a wind turbine or a water conservancy engine is too large (larger than the maximum reasonable requirement of the electrolysis unit), the surplus partial electric energy is output through the direct current interface 02, and the direct current is converted into the direct current matched with the energy storage device 07 through the DC/DC converter 06 to realize the energy supply to the energy storage device 07, so that the electric energy is saved on one hand, and the electrolysis unit can be prevented from being impacted by the excessive current on the other hand; in addition, when the energy supply of the rotary prime motor 01 is too small to meet the minimum requirement of the electrolysis unit, the DC/DC converter 06 converts the DC of the energy storage device 07 into the available DC of the electrolysis unit, thereby supplementing the energy supply gap of the rotary prime motor 01 and ensuring the requirement of the normal electrolysis process of the electrolysis unit.
Preferably, in order to achieve automatic power balance of the electrolytic power supply, in an embodiment of the present invention, a processing unit (not shown in the figure) and a monitoring unit 08 may be further included;
the monitoring unit 08 (such as a voltmeter) is used for collecting voltage data between the cathode plate 122 and the anode plate 123 in real time;
the processing unit is configured to generate a control instruction of the power transmission direction of the inverter-rectifier 04 according to a first preset rule or generate a control instruction of the power transmission direction of the DC/DC converter 06 according to a second preset rule with the voltage data as a parameter.
In practical applications, the first preset rule and the second preset rule may respectively include a set threshold range (the threshold range may be determined according to the maximum reasonable requirement and the minimum requirement of the electrolysis unit), so as to generate a control instruction to output the surplus electric energy of the electrolysis unit through the dc interface 02 after the voltage between the cathode plate 122 and the anode plate 123 exceeds the corresponding threshold range, or input the electric energy to the electrolysis unit through the dc interface 02, so as to realize the power balance of the electrolysis unit.
It should be noted that, in the embodiment of the present invention, specific implementation and technical effects of the power-supplied electrolysis system of the prime mover may refer to the power-supplied electrolysis device of the prime mover corresponding to any one of the first to third embodiments, and will not be described herein.
The above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
