The microwave power supply is connected with the magnetron through a high-voltage wire, and the microwave power supply and the gradually-changed rectangular waveguide are grounded (grounded); the catalytic cooling sleeve part is connected with the surface of the gradually-changed rectangular waveguide through a flange; the magnetron, the vortex air inlet conversion device and the gradually-changed rectangular waveguide are connected through screws; the discharge vessel is fixed to the gas inlet device by means of a ferrule and a gasket, which are mechanically designed to be connected.

The gas source is connected with the gas flow controllers through a conduit.
The hydrogen production device is divided into a microwave plasma part, a catalytic quenching part and a gas supply part. The microwave plasma part consists of a microwave power supply, a magnetron, a gradually-changed rectangular waveguide, a vortex air inlet device and a discharge tube. Generally, microwave plasma can operate at two operating frequencies, one being 2450MHz and the other being 915 MHz; when the vortex gas inlet device works at 2450MHz, the type of the gradually-changed rectangular waveguide is WR-340, the power range of a microwave power supply is 400W-4000W, and the flow range of a vortex gas inlet is 2lpm-20lpm, wherein lpm is lithium per minute and represents liter per minute; working in a 915MHz mode, the gradual change type rectangular waveguide type is WR-975, the microwave power range is 2-50 kW, and the flow range of the vortex air inlet is 15-150 lpm. The vortex gas inlet device converts the gas flow which is axially led into the discharge tube into vortex gas flow. The microwave power supply can be a power supply with stable output voltage, and can also be a microwave power supply with the output voltage waveform changing in a pulse period form. The maximum evaporator power is 1.5 kW.
The catalytic quenching part consists of a catalyst, a cooling water jacket and an air outlet. The catalyst can enable the hot gas flowing out of the plasma torch to be continuously cracked at a preset temperature (the preset temperature is lower than the temperature of the hot gas flowing out of the plasma torch) so as to further generate hydrogen, improve the generation amount of the hydrogen and fully utilize the energy in the waste heat of the gas. The discharge tube (including quartz tube or ceramic tube) is surrounded by water cooling jacket, one is to cool the quartz tube to avoid overheating, the other is to create proper temperature environment for the catalyst, and the third is to achieve the purpose of quenching and force the gas temperature to drop rapidly (because the reaction involved in the hydrogen conversion process is a reversible reaction, the rapid cooling can force the gas temperature to stay as short as possible in the temperature section of the reversible reaction, thereby obtaining higher hydrogen yield and raw material conversion rate). The catalyst is filled in the inner and outer water cooling sleeves. The gas such as hydrogen formed by conversion is led out by the gas outlet.
The gas supply part consists of a gas source, a liquid source, a gas flow controller, a liquid flow controller and an evaporator. The gas source can be selected from argon, helium, nitrogen, gaseous alkane, etc.; the liquid source is usually selected from H2And alcohols such as O, methanol and ethanol with high hydrogen content. The evaporator is used for heating and evaporating the liquid into a gaseous state, simultaneously mixing gas input by the gas source with steam converted from the liquid, and finally outputting the gas to the vortex gas inlet device. The gas flow controller can control the flow rate and the flow rate of the inlet gas, and the liquid flow controller can control the flow rate and the flow rate of the liquid。
The discharge tube is not necessarily cylindrical, and may have other shapes such as a rectangular parallelepiped shape and a special shape. The center of the discharge tube is preferably located at the wavelength of 1/4 wave-guide distance from the short-circuit end face of the wave-guide and is vertical to the center of the wide face of the wave-guide, so as to obtain the maximum microwave electric field and be beneficial to the excitation and formation of microwave plasma. The discharge vessel may also be slightly tilted or not exactly at the 1/4 wavelength waveguide.
The gradually-changed rectangular waveguide has changeable models, and can be made of metal materials such as stainless steel, metal copper and the like; the catalyst can be in the shape of sphere, rod, sheet and the like according to specific situations, and is preferably a porous catalyst with high surface roughness, and the material can be iron-cobalt-nickel, aluminum-based and the like (the catalyst material is not limited, and the material needs to be matched with specific working temperature and cooling water temperature).
The principle of the gas supply part is as follows: the evaporator can control the heating temperature (the maximum heating temperature is 250 degrees centigrade), and can heat and evaporate most of the liquid into a gaseous vapor form. In actual operation, 3 working conditions can be selected: the first is only liquid source, the second is only gas source, and the third is that gas source and liquid source supply simultaneously. When the gas source supplies gas independently, the gas source is alkane such as methane. When the gas source and the liquid source work simultaneously, the gas can be alkane or argon, helium, nitrogen and other gases as carrier gas. Liquid sources are all selected from H2O or alcohol liquid such as methanol, ethanol and the like, and particularly the ethanol can be obtained by fermenting straw grain because the alcohol liquid is obtained and has higher hydrogen content.
Microwave plasma principle: the microwaves are generated by a magnetron microwave source and have a frequency of 2.45GHz or 915 MHz. The microwaves propagate in a tapered rectangular waveguide. The waveguide thickness near the discharge tube is gradually reduced to increase the power density of the microwave transmission, thereby enhancing the microwave electric field, which does not change the conduction mode of the microwave, but facilitates the excitation and maintenance of the plasma. In order to prevent the plasma excited in the reaction cavity from contacting the cavity wall, a fused quartz tube or a ceramic tube is used as a microwave plasma discharge tube to limit the plasma inside. The center of the discharge tube is perpendicular to the center of the broad face of the waveguide at a wavelength 1/4 from the short-circuited end face of the waveguide where the maximum microwave electric field is obtained. The quartz tube is communicated with the atmospheric environment, and the airflow output from the evaporator is tangentially introduced into the vortex air inlet device to convert the airflow in the axial direction into vortex airflow and then enters the discharge tube. One of the functions of the vortex air flow is to stabilize the microwave plasma and restrain the microwave plasma in the discharge tube, and the other function of the vortex air flow is convenient for the wall of the discharge tube to dissipate heat, so that the wall of the discharge tube is prevented from being damaged due to high temperature.
The principle of efficient hydrogen production by microwave plasma is as follows: under atmospheric pressure, the temperature of the microwave plasma gas ranges from 1000K to 9000K, wherein K represents Kelvin, the electron temperature is more than 1eV, the particle density in the plasma is high, and a large number of active particles exist. After the working gas with high hydrogen content enters the plasma, the working gas is subjected to cracking reaction under the collision of a plurality of electrons and active particles in the plasma, so that micromolecular hydrogen molecules and a plurality of other atoms, ions, electrons and other molecules are formed. Taking microwave plasma cracking of ethanol as an example, the reaction principle can be described as follows:
taking microwave plasma cracking methane as an example, the reaction principle can be briefly described as follows:
during hydrogen production, liquid is heated into steam through an evaporator and is introduced into a microwave plasma torch as working gas, so that raw material liquid and a large number of active particles in the plasma are in full contact reaction, and the method has high conversion rate and energy utilization efficiency, and high hydrogen yield and output; and the liquid raw material and the gaseous raw material are compatible at the same time, so that the condition that the raw material is in a gaseous state or a liquid state is not limited.
The gas after coming out of the plasma torch can be fully utilized to generate hydrogen through cracking with the help of the catalyst by combining with the measures of catalysis and quenching, wherein the first purpose of quenching and cooling is to provide the optimal reaction temperature for the catalyst, and the second purpose of quenching and cooling is to force the temperature to be rapidly reduced, skip the reversible reaction temperature interval of the cracking reaction and reduce the occurrence of reverse reaction (the hydrogen reacts with other substances to be combined into other substances).
Examples of hydrogen plants of the present disclosure have the following advantages:
1. the hydrogen production device can work under the atmospheric pressure environment, is easy for industrial application, and can omit complicated additional devices such as pressurization or decompression and the like.
2. Liquid is heated into a steam form through an evaporator and is used as working gas of microwave plasma in a gaseous form, so that liquid substances can fully react in the plasma, the efficiency of producing hydrogen by the microwave plasma can be improved to the greatest extent, and high efficiency is achieved.
3. The large-volume torch-shaped plasma is adopted, so that the method is stable, the treatment efficiency is high, the treatment capacity is large, and the cracking reaction of the raw materials is sufficient.
4. Can be combined with a catalyst to greatly improve the energy conversion efficiency and the gas conversion rate.
5. The catalyst reaction cavity with a quenching measure is adopted, so that the gas conversion rate and the energy conversion rate can be further improved.
6. The microwave plasma device with the structure type has no electrode, pollution reaction and final gas purity degree caused by contact of electrode materials and plasma do not exist, and side reaction caused by the electrode materials does not exist.
7. Each component is modularized, and the evaporator, the catalyst and the condensing part can be selectively used according to specific working conditions.
8. The adopted plasma is waveguide microwave plasma, and the plasma can generate large-volume torch-shaped plasma under atmospheric pressure, thereby being very beneficial to energy conversion application such as gas treatment, hydrogen production, greenhouse gas emission reduction and the like.
9. Gaseous or liquid raw materials can be compatible at the same time.
10. Compared to sliding arc, arc plasma, and similar thermal plasmas, microwave plasma is particularly advantageous in that it does not corrode, contaminate, and require additional energy to cool the electrodes. Low-temperature plasmas such as dielectric barrier discharge plasmas and glow discharge plasmas have low raw material conversion rate and low energy efficiency, and the device has complex process flow operation and is difficult to industrially apply.
