[Technical field]

[0001] The invention relates to the field of microwave technology, in particular to a microwave heating device for heating an energy storage medium and an adsorption medium for heating a hydrogen storage medium and an oxygen storage medium. [Background technology]

[0002] Microwave ovens are well-known heating devices and are widely used as household cooking devices. Traditional microwave ovens convert electrical energy into microwave energy through magnetrons. When the magnetron emits microwave energy at a frequency of about 2450MHZ, the water molecules placed in the microwave oven cavity oscillate at a frequency of 2.45 billion times per second and generate a high-frequency electromagnetic field. Food molecules vibrate in the high-frequency magnetic field, and the molecules collide and rub against each other to generate heat energy, resulting in the heating of food. Traditional microwave ovens have a specific frequency when working, and their operating frequency is relatively low. In addition, traditional microwave ovens are only used to heat a certain amount of food, and their volume is limited to a certain range and cannot be too large or too small. These all limit the application of microwave ovens. [Summary of the invention]

[0003] The present invention aims to solve the above problems and provides a microwave heating device for energy storage medium and adsorption medium, which can select different working frequencies according to different media, increase or decrease the volume according to the processing volume, and can be used either stand-alone or online.

[0004] To achieve the above-mentioned purpose, the present invention provides a microwave heating device for energy storage medium and adsorption medium, which comprises a sealed metal pressure vessel, in which the energy storage medium or adsorption medium to be heated is placed, and the metal pressure vessel is provided with a gas inlet and a gas outlet, respectively, and the metal pressure vessel is connected to a microwave heating component, and the microwave heating component comprises a multi-frequency microwave signal source, a signal amplifier, a ring isolator and an antenna, the ring isolator is respectively connected to the signal amplifier, the antenna and the load, and the antenna is placed in the metal pressure vessel, and the microwave signal generated by the microwave heating component enters the metal pressure vessel through the signal amplifier, the ring isolator and the antenna, and microwave heating is performed on the energy storage medium or adsorption medium therein.

[0005] The energy storage medium is a hydrogen storage medium or an oxygen storage medium, and the adsorption medium includes a physical or chemical adsorption medium between a solid and a gas or a steam.

[0006] Pipe joints are respectively arranged at the gas inlet and the gas outlet of the metal pressure container, and valves for controlling the inlet and outlet of gas and the pressure in the metal pressure container are arranged on the pipe joints.

[0007] A movable material box for containing energy storage medium or adsorption medium is arranged in the metal pressure container, and the material box can be taken out of or put into the metal pressure container.

[0008] The microwave frequency of the multi-frequency microwave signal source is 900MHZ-30GHZ.

[0009] The signal amplifier is a magnetron vacuum amplifier, a solid-state amplifier or an amplifier chip.

[0010] The annular isolator is connected to the antenna and is used to absorb or utilize the microwave energy reflected back by the antenna.

[0011] The load is a microwave resistor.

[0012] A microwave switch is provided between the multi-frequency microwave signal source and the signal amplifier.

[0014] The positive effect of the present invention is that it effectively solves the problems that traditional microwave ovens can only be used for food heating, and the equipment volume and heating frequency are single.

[0019] The following examples are provided to further explain and illustrate the present invention and do not constitute any limitation to the present invention.

[0020] See also Figure 1 The microwave heating device of the energy storage medium and the adsorption medium of the present invention comprises a metal pressure vessel 10 , an energy storage medium or an adsorption medium 20 , a microwave heating component 30 and a load 40 .

[0021] like Figure 2 As shown, the metal pressure vessel 10 is a cylindrical hollow container made of aluminum alloy, stainless steel or other alloy materials. The metal pressure vessel 10 is open at the top, and an upper end cover 17 is bolted to the upper end, and the joint between the upper end cover 17 and the metal pressure vessel 10 is sealed by a sealing ring. When putting in or taking out the energy storage medium or the adsorption medium material, the upper end cover 17 can be opened and put in. The upper end cover 17 is respectively provided with a gas inlet 11 and a gas outlet 12. The gas inlet 11 is used to inject hydrogen, oxygen to be stored and an inert gas such as argon gas for pre-discharging the residual gas in the metal pressure vessel 10, as well as a gas for adsorption medium into the metal pressure vessel 10. The gas outlet 12 is used to extract the residual gas to form a vacuum and discharge the stored gas. Pipe joints 13 and 14 are respectively provided at the gas inlet 11 and the gas outlet 12, and the pipe joints 13 and 14 are respectively connected to the air inlet pipe and the air outlet pipe. The pipe joints 13 and 14 are provided with valves 15 and 16 for controlling the inlet and outlet of gas and the pressure in the metal pressure vessel 10. A movable material box 50 for containing energy storage medium or adsorption medium is provided in the metal pressure vessel 10, and its outer diameter is slightly smaller than the inner diameter of the metal pressure vessel 10. The material box 50 can be taken out of or put into the metal pressure vessel 10. The heated energy storage medium or adsorption medium 20 is pre-placed in the material box 50, and then the material box 50 is placed in the metal pressure vessel 10 for heating.

[0022] The energy storage medium is a hydrogen storage medium or an oxygen storage medium, which can be a known hydrogen storage medium or an oxygen storage medium. The adsorption medium includes a physical or chemical adsorption medium between a solid and a gas or a steam, which can be a known solid and a gas or a known physical or chemical adsorption medium.

[0023] like Figure 3As shown, the metal pressure vessel 10 is connected with a microwave heating assembly 30 for performing microwave heating on the energy storage medium or adsorption medium 20 in the metal pressure vessel 10. The microwave heating assembly 30 includes a multi-frequency microwave signal source 31, a signal amplifier 32, a ring isolator 33 and an antenna 34. The microwave frequency of the multi-frequency microwave signal source 31 is 900MHZ-30GHZ, and the selection of the microwave frequency depends on the material of the energy storage medium or adsorption medium and the volume of the metal pressure vessel 10. When the volume of the metal pressure vessel 10 is small, for example, when its diameter is 20mm, a 10GHZ microwave frequency can be selected for heating. In this embodiment, the preferred microwave frequency is 5.45GHZ. The signal amplifier 32 is a magnetron vacuum amplifier, a solid-state amplifier or an amplifier chip. When the volume of the metal pressure vessel 10 is large, a magnetron vacuum amplifier or a solid-state amplifier can be selected, and when the volume of the metal pressure vessel 10 is small, an amplifier chip can be selected. In this embodiment, a magnetron vacuum amplifier is preferred. A microwave switch 35 is provided between the multi-frequency microwave signal source 31 and the signal amplifier 32. The annular isolator 33 is a microwave isolation device, which is connected to the signal amplifier 32, the antenna 34 and the load 40 respectively. When part of the microwave entering the metal pressure vessel 10 is reflected back by the antenna, the microwave energy is absorbed by the annular isolator 33, and the absorbed microwave energy can also be used, for example, as energy for heating other objects. The antenna 34 is a microwave transmitting and receiving device, and its lower end is inserted into the insulating sleeve 36, and its lower end is electrically connected to the annular isolator 33. The insulating sleeve 36 is fixed by a gland 37, and the gland 37 is fixed to the bottom of the metal pressure vessel 10 by screws, and the joint part between the gland 37 and the metal pressure vessel 10 and the insulating sleeve 36 is sealed by a sealing ring. The upper end of the antenna 34 extends into the metal pressure vessel 10 and is inserted into the antenna sleeve 51 protruding upward from the bottom of the material box 50. In other embodiments, the antenna 34 can also be placed flat on the bottom of the metal pressure vessel 10. The load 40 is a microwave resistor, which is electrically connected to the annular isolator 33 and is used to receive the microwave power absorbed by the annular isolator 33 .

[0024] The above device of the present invention can be used alone or in conjunction with an array of energy storage medium and adsorption medium microwave heating devices. The structure of the array of energy storage medium and adsorption medium microwave heating devices is as follows: Figure 4 shown. Figure 4 In the illustrated embodiment, the air inlet pipes of a plurality of single machines 100 are connected in parallel with each other, and the air outlet pipes are connected in parallel with each other, so as to form a microwave heating device 200 with an array-type energy storage medium and an adsorption medium. The number of the above-mentioned single machines for online connection can be infinitely expanded according to the material processing requirements, thereby greatly improving the processing capacity of the microwave heating device.

[0025] like Figure 1As shown, the microwave signal generated by the microwave heating assembly 30 enters the metal pressure vessel 10 through the signal amplifier 32, the annular isolator 33 and the antenna 34, and performs microwave heating on the energy storage medium or the adsorption medium 20 therein. The volume of the metal pressure vessel 10 and the frequency of the microwave signal are selected according to the different energy storage medium and adsorption medium to be heated.
