The construction of the solid-state hydrogen storage reaction subsystem is described in detail below.
The appearance of the hydrogen storage container 103 is shown in fig. 3. The hydrogen storage container 103 is a sealed casing, generally shaped as a cube or rounded cube, made of a high-strength and high-temperature resistant material, such as an aluminum alloy. A hydrogen storage container gas inlet 104 is provided at the lower part of one side surface of the hydrogen storage container 103, and a hydrogen storage container gas outlet 105 is provided at the upper part of the other side surface opposite to the one side surface. The above-described hydrogen storage container gas inlet 104 and hydrogen storage container gas outlet 105 are not shown in fig. 3, but can be referred to as shown in fig. 1. The gas flowing through the inside of the hydrogen storage container 103 is mainly a hot gas, and the hot gas flows in from the lower part of the hydrogen storage container 103 and then flows out from the upper part, which contributes to smooth flow of the hot gas. In order to prevent heat loss, the outer wall of the hydrogen storage container grid 103 can be wrapped with a heat insulation material.
A plurality of hydrogen storage reaction units 101 are fixedly arranged in the hydrogen storage container grid 103, and each hydrogen storage reaction unit 101 comprises an independent solid hydrogen storage container and a hydrogen conveying pipe. Each solid-state hydrogen storage vessel is provided with a hydrogen delivery pipe, and each hydrogen delivery pipe is connected to the same hydrogen manifold 102. The hydrogen collecting pipe 102 is mainly used for collecting hydrogen released from a single hydrogen storage reaction unit, so that hydrogen collection processing is facilitated, and the hydrogen collecting pipe 102 can balance the pressure in the reaction hydrogen storage unit 101. The high temperature hydrogen in the hydrogen manifold 102 is connected to the hydrogen filtration unit 301 in the hydrogen collection processing subsystem.
The solid state hydrogen storage vessel is cylindrical and is fabricated from a single layer of thin walled stainless steel, preferably 316 stainless steel. The wall thickness of the solid hydrogen storage container is 3-5 mm, so that the solid hydrogen storage container has higher strength and is beneficial to heat conduction. The hydrogen storage reaction units 101 are mainly used for storing solid metal hydride and enabling the stored metal hydride to generate chemical decomposition reaction to release hydrogen under the condition that the heating temperature is higher than 300 ℃. The hydrogen storage reaction units 101 are vertically installed and fixed in the hydrogen storage container lattices 103, the gas inlets 104 of the hydrogen storage container lattices are connected with gas pipelines 205 in the circulating heating subsystem, and the gas outlets 105 of the hydrogen storage container lattices are connected with gas pipelines 210 in the circulating heating subsystem.
Preferably, the length and width of the bottom surface of each hydrogen storage container cell 103 are about 1 meter, and the outer diameter of each solid hydrogen storage container is 30 cm, so that nine solid hydrogen storage containers are vertically arranged on each hydrogen storage container cell 103, and a gap is reserved between the nine solid hydrogen storage containers for gas circulation. The lower part and the middle part of the hydrogen storage container grid 103 are respectively provided with a partition plate 106, each partition plate is provided with nine big holes, and the solid hydrogen storage container is arranged in each big hole and is fixed. The rest positions on the clapboard are provided with vent holes 107.
(II) circulation heating subsystem
The hydronic heating subsystem shown in fig. 1 includes: the structure of the circulation heating subsystem is described in detail below, namely an electric heater 202, a high-temperature gas heat exchanger 201, a high-temperature circulation fan 211, gas pipelines 205, 210 and 213, a cold gas pipeline 207, temperature sensors 206, 209 and 212 and an electromagnetic valve 208.
The electric heater 202 is installed inside the high-temperature gas heat exchanger 201. The high-temperature gas heat exchanger 201 is mainly used for enabling the gas medium to absorb energy emitted by the electric heater 202 and enabling the gas medium to reach a certain temperature; the high temperature gas heat exchanger 201 also plays a fixed role for the electric heater 202. The electric heater 202 provides the required energy for the high-temperature gas heat exchanger 201 through heat conduction, convection and radiation. The high-temperature gas heat exchanger 201 receives the energy of the electric heater 202, and then heats the fluid on the gas side of the heat exchanger to reach a desired temperature. The air inlet of the high-temperature circulating fan 211 is connected with the hydrogen storage container grid 103 through the hydrogen storage container grid gas outlet 105, and the air outlet of the high-temperature circulating fan 211 is connected with the high-temperature gas heat exchanger 201 through the high-temperature gas heat exchanger inlet 204. The high temperature circulating fan 211 provides corresponding power for the circulation of the high temperature gas, so that the heat generated by the electric heater 202 is conducted to each hydrogen storage reaction unit 101 through the heat-conducting gas, and the temperature requirement of the hydrogen storage reaction units 101 is met.
The outlet 203 of the high-temperature gas heat exchanger is connected with a gas pipeline 205, and two temperature heat transmitters are installed on the gas pipeline 205: a temperature transmitter 206 and a temperature transmitter 209, which are used to monitor the temperature of the gas lines. The gas line 205 is further connected to a cold gas line 207 and an electromagnetic valve 208, the cold gas line 207 and the electromagnetic valve 208 are mainly used for adjusting the gas temperature in the pipeline system, and the electromagnetic valve 208 reduces the temperature by controlling the flow rate of the cold gas in the pipeline system. When the gas temperature in the circulation heating subsystem needs to be reduced, that is, the hydrogen storage units in the hydrogen storage container cells 103 need to dissipate heat, the electromagnetic valve 208 is opened to a certain degree according to signals fed back by the temperature sensor 206 and the temperature sensor 209, so as to supplement cooling gas, and adjust the gas temperature in the circulation heating subsystem.
One end of the gas pipeline 205 is connected with the gas inlet 104 of the hydrogen storage container, and the circulating gas exchanges heat with the solid hydrogen storage container when flowing through the outer wall of the solid hydrogen storage container, is used for heating or cooling the solid hydrogen storage material in the solid hydrogen storage container, and then flows out from the gas outlet 105 of the hydrogen storage container. The hydrogen storage container gas outlet 105 is connected with a gas pipeline 210, then the circulating gas enters a high-temperature circulating fan 211, and the high-temperature circulating fan 211 mainly provides power for the gas in the system to overcome the resistance in the system pipeline. Circulating gas enters a gas pipeline 213 after passing through a high-temperature circulating fan 211, a temperature sensor 212 is mounted on the gas pipeline 213, and one end of the gas pipeline 213 is connected with an inlet 204 of the high-temperature gas heat exchanger.
The gas medium can be selected from various gases such as air, steam, high-temperature waste gas and the like, and the gases need to have stable properties under normal working conditions and cannot cause pipeline corrosion or other damages. In addition to using gas as the heat transfer medium, the present invention can also use liquid substance as the heat transfer medium, such as high temperature heat transfer oil. In the scheme of using the liquid heat-conducting medium, the high-temperature circulating fan 211 is replaced by a high-temperature circulating pump.
(III) hydrogen collecting and processing subsystem
The hydrogen collection processing subsystem comprises a hydrogen filtering device 301, a primary cooling device 303 for hydrogen cooling, a secondary cooling device 307, a hydrogen pressurizing device 305, a hydrogen storage device 309, hydrogen pipelines 312, 313, 315, 316, 317 and 318, temperature sensors 302, 304 and 308, pressure sensors 306, 310 and 314, a high-pressure hydrogen using end 311 and a low-pressure hydrogen using end 319.
The temperature of the hydrogen generated by the decomposition of the solid metal hydride is high, and the high-temperature hydrogen in the hydrogen collecting pipe 102 enters a hydrogen collecting and processing subsystem for post-processing, and the structure of the hydrogen collecting and processing subsystem is described in detail below.
The hydrogen filtering device 301 is connected with the hydrogen collecting pipe 102, and hydrogen entering the hydrogen collecting and processing subsystem firstly needs to enter the hydrogen filtering device 301 to filter and separate metal dust particles in hydrogen flow, so that all components in the following system are prevented from being influenced by dust and cannot work normally. The hydrogen passing through the hydrogen filtering device 301 is normal-pressure high-temperature hydrogen, and the temperature can reach 320 ℃. Because the temperature resistance of the components such as the installation joint, the valve and the like in the system is only 80 ℃ at most, the temperature of the hydrogen gas flow needs to be reduced, so that the hydrogen gas flows in the pipeline in a safe temperature range.
Firstly, making high-temperature hydrogen flow enter a primary cooling device 303, and adjusting the cooling power of the primary cooling device 303 according to a temperature sensor 302; then, it is determined whether the pressure of the hydrogen gas cooled by the primary cooling device 303 is normal pressure or normal temperature based on the temperature sensor 304 and the pressure sensor 314. The cooled hydrogen can meet the requirement of the low pressure hydrogen using end 319, and directly enters the low pressure hydrogen using end 319 through the branched hydrogen pipeline 318. The other branched hydrogen gas flows to the high pressure hydrogen gas using terminal 311.
After the hydrogen gas flows through the primary cooling device 303, the requirement of the high-pressure hydrogen gas using end 311 cannot be met, and the normal-pressure hydrogen gas needs to be pressurized to be changed into the high-pressure hydrogen gas. The hydrogen gas flow first enters the hydrogen pressurizing device 305, and the hydrogen pressurizing device 305 is used for pressurizing the hydrogen stored in order to reduce the volume of the hydrogen and meet the requirement of the high-pressure hydrogen using end 311 for the high-pressure hydrogen. Pressure sensors (the pressure sensor 314 and the pressure sensor 306) before and after the hydrogen pressurizing device 305 judge whether the pressurized hydrogen gas satisfies the required pressure, and the maximum pressure after pressurization can reach 70MPa.
The pressurized hydrogen flow is high-temperature and high-pressure hydrogen, so that the pressurized hydrogen needs to be cooled to enable the hydrogen to flow in a safe temperature range in a pipeline. The high-temperature and high-pressure hydrogen gas flow enters a secondary cooling device 307, and the secondary cooling device 307 adjusts the cooling power according to the temperature sensor on the hydrogen pipeline 306. After passing through the secondary cooling device 307, the hydrogen is in a normal temperature and high pressure state, and then enters the hydrogen storage device 309, which can store a large amount of high pressure and normal temperature hydrogen in a centralized manner, and after being centralized, can supply hydrogen for the rear end high pressure hydrogen using end 311 in a centralized manner.
Referring to fig. 5, the present invention also provides a method for providing high and low pressure hydrogen gas to a user using end by using the above system, comprising the following steps:
in the first step, the temperature of the gas in the whole circulation heating subsystem is gradually raised and circularly flows through the electric heater 202, the high-temperature gas heat exchanger 201 and the high-temperature circulating fan 211, and finally reaches more than 300 ℃.
In the second step, when the circulation temperature in the hydrogen storage container 103 reaches 300 ℃, the metal hydride in the hydrogen storage reaction unit 101 starts the hydrogen discharge reaction.
And thirdly, after the hydrogen storage reaction unit 101 discharges hydrogen, all hydrogen is gathered to the hydrogen collecting pipe 102.
Fourthly, the hydrogen from the hydrogen collecting pipe 102 passes through the hydrogen filtering device 301 and the primary cooling device 303 in sequence, one branch of the hydrogen directly enters the low-pressure hydrogen using end 319, and the other branch of the hydrogen directly enters the hydrogen pressurizing device 305, the hydrogen secondary cooling device 307 and the hydrogen storage device 309, and finally reaches the high-pressure hydrogen using end 311.
And step five, after all hydrogen is released by the hydrogen storage reaction unit 101, closing the electric heater 202, opening a cooling gas electromagnetic valve 208 in the cyclic heating subsystem, cooling the system, and turning off the power supply after the whole system reaches normal temperature, thus finishing the operation.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
