Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more+clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Embodiments of the present application are described in further detail below with reference to the accompanying drawings.
The embodiment of the application provides an electrolytic hydrogen production device, which is used for adjusting and controlling the working parameters of electrolytic hydrogen production in a water bath heating mode on the basis of keeping stability in the process of producing hydrogen by using electrolytic water so as to improve the hydrogen production efficiency.
In order to achieve the technical effects, the general idea of the application is as follows:
an electrolytic hydrogen production apparatus, the apparatus comprising:
a first container 1, wherein the first container 1 is used for carrying out electrolytic hydrogen production;
a second container 2 for containing a first liquid for carrying out electrolytic hydrogen production, the second container 2 being in communication with the first container 1;
a third vessel 3 for heating the second vessel 2 by means of water bath heating;
a temperature controller 4 for controlling an electric heater 30 provided in the third tank 3 to heat water in the third tank 3 according to the water temperature in the third tank 3; wherein,
the second container 2 is arranged in the third container 3.
Embodiments of the present application are described in further detail below with reference to the accompanying drawings.
In a first aspect, referring to fig. 1 to 3, an embodiment of the present application provides an electrolytic hydrogen production apparatus, the apparatus comprising:
A first container 1, wherein the first container 1 is used for carrying out electrolytic hydrogen production;
a second container 2 for containing a first liquid for carrying out electrolytic hydrogen production, the second container 2 being in communication with the first container 1;
a third vessel 3 for heating the second vessel 2 by means of water bath heating;
a temperature controller 4 for controlling an electric heater 30 provided in the third tank 3 to heat water in the third tank 3 according to the water temperature in the third tank 3; wherein,
the second container 2 is arranged in the third container 3.
In the embodiment of the present application, the first liquid may specifically be deionized water, where the purity of the pure water in the embodiment of the present application may refer to the pure water used in the electric power system, and the impurity content may be required to be as low as "micrograms/liter", specifically, may be according to the first grade of industrial pure water, that is, the conductivity is less than or equal to 0.1 μs/cm.
The first container 1 is a main functional component, in particular to a hydrogen production electrolytic cell, which comprises an electrolytic cell cathode A, an electrolytic cell anode B and a proton exchange membrane C, and also comprises a waterway pipeline communicated with the second container 2, and is mainly used for carrying out the working condition of electrolytic hydrogen production, so that the volt-ampere characteristic and hydrogen production efficiency in the electrolytic hydrogen production process can be known in the simulation process;
The temperature controller 4 is used for controlling the electric heater 30 to heat the water in the third container 3, so that the pure water temperature in the second container 2 is adjusted in a water bath heating mode, and then the pure water temperature when the first container 1 performs electrolytic hydrogen production is adjusted, so that the temperature environment of the electrolytic hydrogen production is adjusted, and the water bath heating mode ensures the ion content of the pure water in the second container 2 and discharges the interference of metal ions because the heat source of the water bath heating is not in direct contact with the pure water in the second container 2.
The water bath heating means that the electric heater 30 directly heats the water in the third container 3 to raise the temperature of the water in the third container 3, and as the temperature of the water in the third container 3 increases, the water in the third container 3 can transfer heat to the pure water through the side wall of the second container 2, thereby raising the temperature of the pure water in the second container 2, that is, heating the pure water in the second container 2; wherein,
according to the heating requirement of the actual electrolysis operation, materials with proper heat conduction performance are selected to manufacture the second container 2 and the third container 3.
In the embodiment of the application, in the process of producing hydrogen by electrolyzing water, the working parameters of the hydrogen production are regulated and controlled in a water bath heating mode on the basis of keeping stability so as to improve the hydrogen production efficiency; wherein,
The specifically adjusted electrolytic hydrogen production operating parameters include the operating voltage or operating current of the cathode and anode in the first vessel 1, the temperatures of the cathode and anode in the first vessel 1, the internal temperatures of the first vessel 1, the second vessel 2, and the third vessel 3, the flow rate of the first liquid into the first vessel 1, and the flow rate of the hydrogen produced.
According to the technical scheme provided by the embodiment of the application, when the electrolytic hydrogen production device is used for electrolytic hydrogen production, the electrolytic hydrogen production device comprises the following operation parts:
first part, flow control:
according to the working requirement of the hydrogen production electrolytic cell, corresponding flow values are input into the upper computer, and the electric control system can change the magnitude of a control current signal input into the micropump according to the input values, so that the rotating speed is changed, the required flow output is achieved, and the first liquid in the second container 2 is controlled to enter the first container 1.
Second part, temperature control:
according to the working requirement of the hydrogen production electrolytic cell, a corresponding target temperature value is input into an upper computer, and an electric control system changes the control current of the electric heater 30 in the third container 3 according to the input target temperature value, so that the heating power of the electric heater 30 is changed, the temperature of water in the third container 3 is changed, and the temperature of the first liquid in the second container 2 is changed in a water bath heating mode;
Meanwhile, the corresponding thermocouple feeds back the temperature monitored in real time to the temperature control system, and controls the starting and stopping of the electric heater 30 according to the set target temperature value, so that the water temperature in the third container 3 deviates up and down at the set value, and the water temperature is not excessively high due to continuous heating of the electric heater 30.
When necessary, because the heat is dissipated from the pipeline, the heat can reach the first container 1, namely after the hydrogen production electrolytic cell, the actual temperature is lower than the temperature required by the test, and an auxiliary heating system is needed;
the auxiliary heating rod is inserted into the first container 1, namely the end plate of the electrolytic cell, and is combined with the thermocouple and the temperature control system to control the temperature, and the principle is the same as that described above, the electric heater 30 is used as the main control temperature, and the main control temperature and the auxiliary control temperature work together to achieve accurate temperature control;
wherein the electric heater 30 may be an electric heating rod.
Third part, power control:
according to the working requirement of the hydrogen production electrolytic cell, a corresponding current and voltage value is input into the upper computer, the direct current power supply module can supply power to the first container 1, namely the hydrogen production electrolytic cell, specifically controls the cathode and the anode in the first container 1, namely the cathode and the anode of the electrolytic cell, and simultaneously feeds back the real-time voltage and current of the electrolytic cell to the upper computer to form a current and voltage real-time curve.
Fourth part, hydrogen production flow monitoring:
after the electrolytic hydrogen production, hydrogen is produced in the hydrogen discharge pipeline, the working efficiency of the electrolytic cell can be judged according to the flow of hydrogen produced in unit current time, and the working power of the cathode and the anode in the first container 1 can be adjusted;
if necessary, in order to ensure the monitoring precision, the hydrogen flowmeter used for flow monitoring can be replaced by a hydrogen flow sensor.
Further, the electrolytic hydrogen production device further comprises:
a cell cathode heater chip 10 disposed on the cathode of the first container 1;
an electrolytic cell anode heating plate 11 provided on the anode of the first container 1;
the temperature controller 4 is also used for controlling the cathode heating plate 10 of the electrolytic cell and the anode heating plate 11 of the electrolytic cell to respectively regulate the temperature of the cathode and the anode according to the temperature of the cathode and the anode of the first container 1.

the temperature controller 4 is further configured to control the auxiliary heater 14 to heat the interior of the first container 1 according to the second heating cycle based on the temperature of the interior of the first container 1 and the second target temperature.
Here, the operation flow of the electric heater 30 and the auxiliary heater 14 will be specifically described:
when the electrolytic hydrogen production starts, the electric heater 30 is controlled to work firstly, preheating operation is carried out, so that water in the third container 3 reaches a corresponding preset temperature, and then the second container 2 is heated in a water bath heating mode, so that the temperature of the first liquid in the second container 2 reaches a corresponding preset temperature;
further, the electrolytic hydrogen production is performed while monitoring the temperature of the first liquid in the second container 2 and the temperature inside the first container 1,
since heat loss may occur in the process of transferring the first liquid from the second container 2 to the first container 1, it is necessary to provide an insulation layer on a pipe for transferring the first liquid from the second container 2 to the first container 1, and also to perform combined temperature control by using the electric heater 30 and the auxiliary heater 14.
When the temperature difference between the temperature of the first liquid in the second container 2 and the corresponding preset temperature exceeds the corresponding temperature difference threshold in the joint temperature control, the electric heater 30 is controlled to heat the water in the third container 3 according to the first heating period, so that the temperature difference between the temperature of the first liquid in the second container 2 and the corresponding preset temperature is smaller than the corresponding temperature difference threshold,
when the temperature difference between the temperature of the first liquid in the first container 1 and the corresponding preset temperature exceeds the corresponding temperature difference threshold, controlling the auxiliary heater 14 to heat the interior of the first container 1 according to the second heating period, wherein the temperature difference between the temperature of the first liquid in the first container 1 and the corresponding preset temperature is smaller than the corresponding temperature difference threshold;
it should be noted that, the periodic heating mode is adopted to slowly raise the temperature to a certain extent in a controllable manner, so as to achieve the effect of combined temperature control and avoid heat dissipation caused by the problem of hardware structure.
When the combined temperature control is implemented in particular, the preset temperature can be 60 ℃, and the temperature difference threshold can be 1 ℃;
the first heating period and the second heating period may be 1 second or 2 seconds or other values, and each of the first heating period and the second heating period may be separated by a preset interval time, for example, 1 second or 2 seconds;
That is, when the temperature difference between the temperature of the first liquid in the first container 1 and the corresponding preset temperature exceeds the corresponding temperature difference threshold, the auxiliary heater 14 heats for 1 second, then stops for 1 second, and then stops for 1 second, until the temperature difference between the temperature of the first liquid in the first container 1 and the corresponding preset temperature is smaller than the corresponding temperature difference threshold, the operation mode of the electric heater 30 is similar.
