Example 1
In order to eliminate the defects of excessively complex structure or excessive energy loss in the energy conversion process of the electrolysis unit of the power supply balance device in the prior art, referring to fig. 1 to 7, a power balance prime mover electrolysis device is provided in an embodiment of the present invention, and the power balance prime mover electrolysis device comprises a power generation-motor 02 connected with a rotary prime mover 01, a transmission component 03 and an electrolysis unit; the electrolysis unit comprises a rotatable magnetic circuit 11 and an annular electrolysis cell 12;
the annular electrolytic cell 12 is filled with electrolyte; the annular electrolytic cell 12 includes a cell membrane 121; the cell membrane 121 serves to divide 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; a short circuit between the cathode plate 122 and the anode plate 123;
the rotatable magnetic circuit 11 includes a rotating 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 pole shoe pairs (e.g., first pole shoe 112 and second pole shoe 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 motor 01, and two torque output ends of the other end of the transmission part 03 are respectively in transmission connection with the generator-motor 02 and the rotating shaft 111 and are used for alternatively or simultaneously driving the generator-motor 02 and the rotating shaft 111; in practical applications, the transmission connection between the transmission member 03 and the generator-motor 02 and the rotation shaft 111 may be referred to as a clutch connection or a gear engagement.
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 generator-motor 02 is connected to an external power grid 04 in a grid-connected manner, and is used for outputting power to the power grid 04 or receiving power from the power grid 04 according to a first preset rule; when the generator-motor 02 receives power from the power grid 04, torque is generated to the rotating shaft 111 via the transmission 03.
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 reason, in the embodiment of the present invention, as shown in fig. 2, a generator-motor 02 having a bi-directional power function is employed to output surplus power of the rotary prime mover 01 to the outside or input power as a motor to the rotating shaft 111; specifically, when the output force of the rotating prime mover 01 such as a wind turbine or a hydraulic engine is too large (larger than the maximum reasonable requirement of the electrolysis unit), the generator-motor 02 is used as a generator to generate electricity by using the surplus power of the rotating prime mover 01, and surplus partial power is output to the power grid 04, so that on one hand, electric energy is saved, and on the other hand, the electrolysis unit can be prevented from being impacted by excessive current; when the output of the rotary prime motor 01 is insufficient, the generator-motor 02 is used as a motor to supplement a power gap of the rotary prime motor 01 by using the electric energy transmitted by the power grid 04 to assist in driving the rotating shaft 111 so as to meet the power requirement of the electrolysis unit; thereby ensuring the requirements of the normal electrolysis process of the electrolysis unit.
In addition, similar to the grid-connected connection of the generator-motor 02 to the external power grid 04, as shown in fig. 3, in the embodiment of the present invention, the generator-motor 02 may be electrically connected to the energy storage device 05 (e.g., a battery) for outputting electric energy to the energy storage device 05 or receiving electric energy from the energy storage device 05. Specifically, when the output force of the rotating prime mover 01 such as a wind turbine or a hydraulic engine is too large (larger than the maximum reasonable requirement of the electrolysis unit), the generator-motor 02 is used as a generator to generate electricity by using the excessive power of the rotating prime mover 01, and the excessive partial power is output to the energy storage device 05, so that on one hand, the electric energy is saved, and on the other hand, the electrolysis unit can be prevented from being impacted by excessive current; when the output of the rotary prime motor 01 is insufficient, the generator-motor 02 is used as a motor to assist in driving the rotating shaft 111 by utilizing the electric energy transmitted by the energy storage device 05 to complement the power gap of the rotary prime motor 01 so as to meet the power requirement of the electrolysis unit; thereby ensuring the requirements 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 figures) and a monitoring unit 06 may be further included;
the monitoring unit 06 (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 command of the power transmission direction of the generator-motor 02 (i.e. using it as a generator or a motor) according to the first preset rule or according to the second preset rule, with the voltage data as a parameter.
In practical applications, the first preset rule and the second preset rule may 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) respectively, so as to generate a control instruction to output the surplus electric energy of the electrolysis unit through the generator-motor 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 generator-motor 02, so as to realize the power balance of the electrolysis unit.
In practical applications, the transmission member 03 drivingly connected to the rotary prime mover 01, the generator-motor 02 and the rotation shaft 111, respectively, may be configured as shown in fig. 4, including a driving shaft 31 connected to the rotary prime mover 01, a driven shaft 32 connected to the rotation shaft 111, and an auxiliary shaft 33 connected to the generator-motor 02; the driving shaft 31, the driven shaft 32 and the auxiliary shaft 33 are connected in a meshed manner; when the rotary prime mover 01 drives the driving shaft 31 to rotate, the driven shaft 32 is driven to rotate, and the auxiliary shaft 33 is detachably engaged; the engaged auxiliary shaft 33 may be driven by the generator-motor 02 to generate power, or may be driven by the generator-motor 02 to output torque to the driven shaft 32 to perform auxiliary work.
As shown in fig. 2 and 3, in the embodiment of the invention, a direct current power supply is not required to be arranged for the electrolytic cell, and induced potential and induced current are directly generated between the electrolyte at two sides of the diaphragm of the electrolytic cell, so that the electrolyte is electrolyzed; the working principle of the embodiment of the invention is that when the rotary prime motor outputs mechanical energy, the transmission part 13 can drive the rotation 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. 5, 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. 6, 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 ：
Figure BDA0003327591210000091
In induced electric field E i Under the action, cations in the electrolyte migrate to the cathode direction, anions migrate to the anode direction, and the generated current density J is as follows:
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, when the magnet is an electromagnet, in the embodiment of the present invention, an electromagnetic control unit (not shown in the figure) may be further provided, and the electromagnetic control unit controls the electrolysis rate of the electrolyte by adjusting the electromagnetic strength of the magnet.
Preferably, in the embodiment of the present invention, the anode plate and the cathode plate may also be provided with an external voltage monitoring unit (not shown in the figure) to monitor the voltage of the electrolytic cell, so as to reflect the charging degree.
Further, as shown in fig. 7, 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 storage batteries or storage battery groups 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.
Further, in the embodiment of the present invention, an inverter (not shown in the figure) may be further connected to the dc output interface, so that ac power output to the power grid may be achieved.
In summary, in the embodiment of the present invention, the power-balanced prime mover electrolytic device is provided, in which the electrolytic cell is provided in a ring shape, and a rotatable magnetic circuit capable of generating an induced potential and an induced current in the electrolyte between the cathode chamber and the anode chamber of the ring-shaped electrolytic cell when rotated is provided, so that the induced potential and the induced current for electrolytically storing the electrolyte can be generated in the electrolyte by the mechanical energy driving of the rotating prime mover after the transmission member is provided in transmission connection with the rotating prime mover.
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 device and reducing the energy loss caused by energy conversion.
In addition, since the power generation-motor can be connected with an external power grid or an energy storage device, 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, so that the stability of the electrolysis process is effectively improved.
Example two
On the basis of the first embodiment, it is preferable that 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, 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 electrolytic cell and its rotation allows for magnetic field rotation. The magnetic induction intensity of the rotatable magnetic circuit 11 in the electrolytic cell 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. 6, an anode reaction occurs on the inside and a cathode reaction occurs on the outside.
It should be noted that, the specific implementation manner and the technical effect of the power-balanced prime mover electrolysis system in the embodiment of the present invention may refer to the power-balanced prime mover electrolysis device corresponding to the first embodiment, and will not be described herein.

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.

Example IV
In another aspect of the embodiments of the present invention, there is further provided a power-balanced prime mover electrolysis system, as shown in fig. 2 or 3, including a rotary prime mover and the power-balanced prime mover electrolysis apparatus described in the above embodiments;
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 reason, in the embodiment of the present invention, as shown in fig. 2, a generator-motor 02 having a bi-directional power function is employed to output surplus power of the rotary prime mover 01 to the outside or input power as a motor to the rotating shaft 111; specifically, when the output force of the rotating prime mover 01 such as a wind turbine or a hydraulic engine is too large (larger than the maximum reasonable requirement of the electrolysis unit), the generator-motor 02 is used as a generator to generate electricity by using the surplus power of the rotating prime mover 01, and surplus partial power is output to the power grid 04, so that on one hand, electric energy is saved, and on the other hand, the electrolysis unit can be prevented from being impacted by excessive current; when the output of the rotary prime motor 01 is insufficient, the generator-motor 02 is used as a motor to supplement a power gap of the rotary prime motor 01 by using the electric energy transmitted by the power grid 04 to assist in driving the rotating shaft 111 so as to meet the power requirement of the electrolysis unit; thereby ensuring the requirements of the normal electrolysis process of the electrolysis unit.
In addition, similar to the grid-connected connection of the generator-motor 02 to the external power grid 04, as shown in fig. 3, in the embodiment of the present invention, the generator-motor 02 may be electrically connected to the energy storage device 05 (e.g., a battery) for outputting electric energy to the energy storage device 05 or receiving electric energy from the energy storage device 05. Specifically, when the output force of the rotating prime mover 01 such as a wind turbine or a hydraulic engine is too large (larger than the maximum reasonable requirement of the electrolysis unit), the generator-motor 02 is used as a generator to generate electricity by using the excessive power of the rotating prime mover 01, and the excessive partial power is output to the energy storage device 05, so that on one hand, the electric energy is saved, and on the other hand, the electrolysis unit can be prevented from being impacted by excessive current; when the output of the rotary prime motor 01 is insufficient, the generator-motor 02 is used as a motor to assist in driving the rotating shaft 111 by utilizing the electric energy transmitted by the energy storage device 05 to complement the power gap of the rotary prime motor 01 so as to meet the power requirement of the electrolysis unit; thereby ensuring the requirements 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 figures) and a monitoring unit 06 may be further included;
the monitoring unit 06 (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 command of the power transmission direction of the generator-motor 02 (i.e. using it as a generator or a motor) according to the first preset rule or according to the second preset rule, with the voltage data as a parameter.
In practical applications, the first preset rule and the second preset rule may 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) respectively, so as to generate a control instruction to output the surplus electric energy of the electrolysis unit through the generator-motor 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 generator-motor 02, so as to realize the power balance of the electrolysis unit.
In the embodiment of the present invention, two torque output ends at the other end of the transmission component 03 are respectively connected with the generator-motor 02 and the rotation shaft 111 in a transmission manner, and are used for alternatively or simultaneously driving the generator-motor 02 and the rotation shaft 111, and in addition, when the generator-motor 02 is used as a motor, the rotation motor 01 can be rotated to drive the rotation shaft 111 and simultaneously output torque to the rotation shaft 111 as auxiliary driving to apply work.
In practical applications, the transmission member 03 drivingly connected to the rotary prime mover 01, the generator-motor 02 and the rotation shaft 111, respectively, may be configured as shown in fig. 4, including a driving shaft 31 connected to the rotary prime mover 01, a driven shaft 32 connected to the rotation shaft 111, and an auxiliary shaft 33 connected to the generator-motor 02; the driving shaft 31, the driven shaft 32 and the auxiliary shaft 33 are in meshed connection; when the rotary prime mover 01 drives the driving shaft 31 to rotate, the driven shaft 32 is driven to rotate, and the auxiliary shaft 33 is detachably engaged; the engaged auxiliary shaft 33 may be driven by the generator-motor 02 to generate power, or may be driven by the generator-motor 02 to output torque to the driven shaft 32 to perform auxiliary work.
It should be noted that, the specific implementation manner and the technical effect of the power-balanced prime mover electrolysis system in the embodiment of the present invention may refer to the power-balanced prime mover electrolysis device corresponding to the first embodiment, 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.
