Description

Technical Field

[0001] This invention relates to the field of RV accessory technology, specifically a new energy hydrogen stove. Background Technology

[0002] With the improvement of living standards, more and more families are choosing to travel in RVs. RVs integrate clothing, food, accommodation, and transportation, realizing the concept of living while traveling and traveling while living. As a platform for outdoor and camping life, energy is naturally very important. Because RVs are highly mobile, it is essential to carry, store, and generate energy on their own when it is inconvenient to connect to external energy networks (electricity, gas, etc.). Many RVs are equipped with induction cookers, which have high power and high energy consumption. Therefore, they need to be equipped with high-power batteries or generators. However, high-power batteries are expensive, and generators are highly dependent on gasoline or diesel, and their noise and exhaust fumes make them unsuitable for long-term use. Therefore, some RVs are equipped with gas stoves, which are quiet, energy-efficient, clean, and hygienic, making them popular among RV enthusiasts.

[0003] However, existing RV gas stoves are usually equipped with gas cylinders, which need to be filled at the gas processing point and placed on the vehicle.

Detailed Implementation

[0022] Please see Figures 1-4In this embodiment of the invention, a new energy hydrogen stove includes a photovoltaic power generation system, an electrolytic hydrogen production system, a primary dehydration system, a hydrogen storage system, and a hydrogen stove system. The electrolytic hydrogen production system includes a water tank 1, a water purification tank 2, a water exhaust fan 3, an electrolytic cell 5, a resin tank 6, and a water pump 7. The inlet of the water purification tank 2 is connected to the external municipal tap water supply, and the outlet of the water purification tank 2 is connected to the inlet of the water tank 1. The water purification tank 2 is filled with activated carbon filter media. After removing impurities from the municipal tap water, the purified water is sent to the water tank 1. The outlet of the water tank 1 is connected to the water... The inlet of pump 7 is connected to the outlet of the water pump 7 and the inlet of resin tank 6. The resin tank 6 is filled with ion exchange resin to remove hardness ions such as calcium and magnesium from the water. A water tank level gauge 102 is installed inside the water tank 1. The water level in the water tank 1 can be monitored by the water tank level gauge 102. When the water in the water tank 1 is insufficient, water can be added to the water tank 1. A manual drain valve 101 is installed at the lower end of the outside of the water tank 1. When the water in the water tank 1 is too much, the manual drain valve 101 can be opened to drain the water in the water tank 1.

[0023] The hydrogen stove system includes a hydrogen burner head 9. The input end of the hydrogen burner head 9 is connected to a pressure regulating valve 902 via a gas pipe. The input end of the pressure regulating valve 902 is connected to a pressure transmitter 901 via a gas pipe. The input end of the pressure transmitter 901 is connected to the output end of the hydrogen storage tank 10 via a gas pipe. The pressure transmitter 901 transmits the hydrogen pressure signal to the pressure regulating valve 902 and displays the pressure. The pressure regulating valve 902 adjusts the hydrogen output pressure of the hydrogen storage tank 10 to meet the gas flow required for combustion of the hydrogen burner head 9, thus enabling boiling water, cooking rice, and other cooking activities.

[0024] exist Figure 3 In the photovoltaic power generation system, there are solar panels 4 and voltage regulator 401. The solar panels 4 are electrically connected to a solar controller, a battery and an inverter. The inverter and voltage regulator 401 are electrically connected. The voltage regulator 401 supplies electrical energy to the electrolytic cell 5 through a circuit. The electrical energy generated by the solar panels 4 under sunlight is used to charge the battery through the solar controller. Then, the inverter converts the direct current from the battery into alternating current. Alternatively, the solar controller can directly convert the electrical energy generated by the solar panels 4 into alternating current through the inverter. Then, the voltage regulator 401 adjusts the voltage of the alternating current to a set value, which can then energize the cathode rod 504 and anode rod 505 inside the electrolytic cell 5, electrolyzing the water in the electrolytic cell 5 into oxygen and hydrogen.

[0025] exist Figure 3In the electrolytic cell 5, cathode rods 504 and anode rods 505 are located on the left and right sides inside. Diaphragms 503 are respectively installed on the outer sides of the cathode rods 504 and anode rods 505 inside the electrolytic cell 5. Oxygen outlets 507 and hydrogen outlets 502 are respectively installed on the upper side of the corresponding diaphragms 503 on the outer sides of the cathode rods 504 and anode rods 505. A water inlet connector 506 is installed at one end of the outer side of the electrolytic cell 5. The positive and negative terminals of the voltage regulator 401 are electrically connected to the anode rods 505 and cathode rods 504, respectively. The water inlet connector 506 is connected to the outlet of the resin tank 6, and a TDS water quality sensor 501 is installed between them to monitor whether the water quality after purification by the resin tank 6 meets the standards. The oxygen outlet 507 is connected to the inlet of the water exhaust fan 3, and a water flow temperature sensor 302 is installed between them to monitor whether the water quality meets the standards. 2. Monitor whether the temperature of the return water exceeds the standard. Gas cannot pass through the diaphragm 503, while water can pass through the diaphragm 503 freely. Therefore, the diaphragm 503 can prevent oxygen and hydrogen from mixing. When the purified water flowing in from the water inlet 506 enters the electrolytic cell 5, the purified water seeps into the diaphragm 503. Connect the cathode rod 504 to the negative terminal of the voltage regulator 401 and connect the anode rod 505 to the positive terminal of the voltage regulator 401. After power is applied, hydrogen can be generated around the cathode rod 504. The generated hydrogen enters the buffer tank 8 from the hydrogen outlet 502. At the same time, oxygen is generated around the anode rod 505. The generated oxygen can be directly discharged into the air. The temperature of the return water in the electrolytic cell 5 is monitored by the water flow temperature sensor 302. When the temperature exceeds the set value, the water exhaust fan 3 and the water flow switch 301 are turned on. The water exhaust fan 3 cools down the return water. The cooled return water then enters the water tank 1.

[0026] exist Figure 4The primary dehydration system includes a buffer tank 8. An inlet 804 for inputting wet hydrogen is located at the middle of the left end of the buffer tank 8, and an outlet 806 for outputting dry hydrogen is located at the upper end of the buffer tank 8. A condensate tank 803 is located at the bottom of the interior of the buffer tank 8. An ultrasonic level sensor 801 for monitoring the condensate level is installed at the lower inner side of the condensate tank 803. A condensate return water connector 802 for discharging condensate is located on the left side of the condensate tank 803. The inlet 804 is connected to the hydrogen outlet 502 via a gas pipe, and the outlet 806 is connected to the gas inlet of the hydrogen storage tank 10 via a gas pipe. The condensate return water connector 802 is connected to the water tank 1 via a water pipe, and a solenoid valve 103 is installed between the two. The minimum water level in the condensate tank 803 is higher than that in the water tank 1. The water level in the condensate tank 803 is monitored by an ultrasonic level sensor 801. When the water level exceeds the set value, the solenoid valve 103 is opened, and the condensate in the condensate tank 803 automatically flows into the water tank 1. An evaporator 805 is installed inside the buffer tank 8 at the top of the condensate tank 803. A condenser 807 is installed on one side of the evaporator 805. A compressor 808 is installed between the evaporator 805 and the condenser 807. The compressor 808 lowers the surface of the evaporator 805 to below the dew point. After the humid hydrogen enters the evaporator 805 through the inlet 804, the water in the hydrogen condenses into liquid water through heat exchange. The liquid water falls into the condensate tank 803 under the action of gravity. The dried hydrogen, after the water has been removed, enters the hydrogen storage tank 10 through the outlet 806.

[0027] exist Figure 1 In the process, the hydrogen storage system is a hydrogen storage tank 10. The output end of the buffer tank 8 is connected to the input end of the hydrogen storage tank 10. The hydrogen gas, after being dehydrated and dried by the electrolysis cell 5, is stored in the hydrogen storage tank 10 to ensure stable gas pressure in the pipeline and reduce the unevenness of pipeline flow.

[0028] The working principle of this invention is as follows: When hydrogen needs to be produced and a hydrogen stove is used, firstly, the solar panel 4 is installed on the roof of the RV. The electrical energy generated by the solar panel 4 under sunlight is used to charge the battery through the solar controller and store the electrical energy in the battery.

[0029] Next, municipal tap water is added to the water purification tank 2. The activated carbon filter in the water purification tank 2 removes impurities from the municipal tap water before it is fed into the water tank 1. Then, the water pump 7 is turned on, pumping water from the water tank 1 into the resin tank 6. The ion exchange resin in the resin tank 6 removes hardness ions such as calcium and magnesium from the water, and the TDS water quality sensor 501 checks whether the water quality meets the standards. Once the purified water meets the standards, it enters the electrolysis cell 5 through the inlet connector 506 and then permeates into the diaphragm 503. Next, the cathode rod 504 is connected to the negative terminal of the voltage regulator 401, and the anode rod 505 is connected to the voltage regulator 401. The positive electrode of 1 converts the DC power from the battery into AC power through an inverter, and then the voltage of the AC power is adjusted to the set value through a voltage regulator 401. After power is applied, hydrogen gas is generated around the cathode rod 504. The generated hydrogen gas enters the buffer tank 8 through the hydrogen gas outlet 502. At the same time, oxygen gas is generated around the anode rod 505. The generated oxygen gas can be directly discharged into the air. The temperature of the return water in the electrolytic cell 5 is monitored by the water flow temperature sensor 302. When the temperature exceeds the set value, the water exhaust fan 3 and the water flow switch 301 are turned on. The water exhaust fan 3 cools down the return water. The cooled return water then enters the water tank 1.

[0030] Before hydrogen enters the buffer tank 8, the compressor 808 is turned on. The compressor 808 lowers the surface of the evaporator 805 below the dew point. When the moist hydrogen enters the evaporator 805 through the inlet 804, the water in the hydrogen condenses into liquid water through heat exchange. The liquid water falls into the condensate tank 803 under the action of gravity. The dried hydrogen, after the water has been removed, enters the hydrogen storage tank 10 through the outlet 806.

[0031] When the hydrogen stove head 9 is needed, the pressure signal of the hydrogen is transmitted to the pressure regulating valve 902 through the pressure transmitter 901 and the pressure is displayed. The hydrogen output pressure of the hydrogen storage tank 10 is adjusted by the pressure regulating valve 902 to meet the gas flow required for combustion of the hydrogen stove head 9, so that it can be used for boiling water, cooking rice, cooking dishes, etc.

[0032] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
