Detailed Description
The present invention will be described in further detail below with reference to the drawings, wherein like parts are designated by like reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower", "bottom" and "top" used in the following description refer to directions in the drawings, and the words "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.
The microwave plasma furnace device, as shown in connection with fig. 1 and 2, comprises a stove top plate 1, a torch generator 2 arranged below the stove top plate 1, and a management control module 3 and an air supply module 4 which are connected with the torch generator 2, wherein in use, the torch generator 2 generates ion flame by adjusting the management control module 3, and meanwhile, working gas is supplied into the torch generator 2 by the air supply module 4, so that the flame is kept stable.
As shown in fig. 2 and 3, the torch generator 2 includes a microwave cavity 21, a microwave generator 22 disposed at the lower side of the microwave cavity 21, and a discharge tube 23 disposed in the microwave cavity 21, wherein the discharge tube 23 vertically penetrates through the microwave cavity 21, the upper end is provided with a fire outlet 231, and the lower end is provided with an air inlet 232. An ignition conductor 24 is mounted in the inner cavity of the discharge tube 23, and the ignition conductor 24 is positioned in a tube section adjacent to the inside of the microwave cavity 21, and in use, the microwave generator 22 is adjusted to generate an electromagnetic field in the microwave cavity 21 so that the internal ignition conductor 24 generates an ion flame.
Microwaves propagate within the microwave cavity 21 such that the spatial electromagnetic field is enhanced, inducing intense gas ionization to generate a plasma. The microwave plasma is generated without electrodes, so that air can be working gas, corrosion of the electrodes is prevented, and the electrodes used in the arc plasma furnace are not required to be replaced. The microwave plasma has higher electrothermal conversion efficiency, particularly, fossil fuel is not needed for generating high-temperature flame, only electric energy is needed to be provided, gas pollution at a user terminal is avoided, and the microwave plasma has great application potential in the aspect of a miniaturized high-temperature plasma cooking range.
Wherein the microwave cavity 21 is fixed at the lower side of the cooktop plate 1, the microwave generator 22 is fixed at one side of the microwave cavity 21 at the level, and a microwave electric field is provided to the microwave cavity 21 through the microwave generator 22.
The microwave cavity 21 is thicker near the microwave generator 22 and thinner at a side far from the microwave generator 22 in the horizontal direction, and the position is a contracted section 211 of the microwave cavity 21, and in the contracted section 211, the amplitude of the microwave electric field in the microwave cavity 21 is the largest, so that the flame can be generated more smoothly in the discharge tube 23, and the discharge tube 23 is arranged in the contracted section 211.
In use, microwaves pass through the microwave cavity 21, so that the electromagnetic field in the space is enhanced, and a microwave plasma flame can be released at the position of the discharge tube 23.
In order to make it easier for the ignition conductor 24 to excite the microwave plasma, the discharge tube 23 is provided at a position whose axis is distant from the rear end face (1/4λ+kλ) of the microwave cavity 21, where λ is the wavelength of the microwave in the system and k is an integer of 0 or more, wherein the above-mentioned rear end face of the microwave cavity 21 refers to the end of the microwave cavity 21 horizontally distant from the microwave generator 22. The microwave electric field amplitude of the position is maximum, so that microwave plasma is easy to excite.
The ignition conductor 24 is made of a high temperature resistant material, such as tungsten, iron, copper, etc., and is annular, and the ignition conductor 24 is embedded in the discharge tube 23 during installation, wherein the side wall of the ignition conductor 24 can be in a thread shape or a grid shape, and is tubular, so that the ignition conductor 24 is not in direct contact with plasma during use, thereby preventing the ignition conductor 24 from being ablated, and prolonging the service life of the ignition conductor 24. In order to better excite the plasma, a discharge tip 241 is formed on the ignition conductor 24 so as to extend to one side of the middle, and the discharge tip 241 is made of a high-temperature resistant conductive material.
It should be noted that, the discharge tube 23 is a quartz microwave discharge tube 23, and the discharge tube 23 has better heat resistance and longer service life.
In use of the device, the plenum module 4 may provide air into the discharge tube 23 to cause the internal plasma flame to operate steadily. The air supply module 4 includes an air inlet pipe 43 fixed to the microwave cavity 21 and communicating with the discharge tube 23, an air pump 41, and an air guide pipe 42 having one end communicating with the air pump 41 and the other end communicating with the air inlet pipe 43, and can control the flame temperature by adjusting the air supply amount of the air pump 41.
One end of the air duct 42 passes through the air inlet pipe 43 and is communicated with the inner cavity of the air inlet pipe 43. Wherein the air duct 42 is flush with the inner wall of the air inlet pipe 43, and the included angle a between the axial line of the pipe section at the joint of the air duct and the air inlet pipe and the axial line of the air inlet pipe is 10-80 degrees. By the above-described angle setting of the air jet direction, the air flow of the sheet injected into the discharge tube 23 is made to be a swirling air flow. Therefore, when the plasma flame is sprayed out from the flame outlet 231, the flame can better contact with a heating object, and the heat transfer efficiency is improved. The composition of the working gas introduced through the gas guide tube 42 may be air, oxygen, nitrogen, argon, or the like.
Through the air inlet pipe 43, when in use, the conductor absorbs microwave energy and the air inlet pipe 43 generates instant flashover, seed electrons are provided, so that microwave plasma is easy to excite; after microwave plasma excitation, microwave energy is transferred into the plasma, the ignition conductor 24 does not absorb energy, and the flashover time is very short; the working gas swirls into the core region of the microwave plasma, so that a certain distance exists between the microwave plasma and the inner wall of the discharge tube 23, and the working gas also plays a role in cooling. Combining the above two effects, the ignition conductor 24 life is greatly extended. After the microwave plasma is accidentally extinguished, the conductor absorbs the microwave energy and ignites again, which can re-ignite the plasma.
As shown in connection with fig. 1 and 4, the stove top plate 1 is provided with a stove support 11, wherein the fire outlet 231 of the discharge tube 23 is located at the center of the stove support 11, so that flames can be conveniently and well ejected from the stove support 11.
For convenience of use, buttons 12 for adjusting the size of the microwaves and the air flow are provided on the cooking top plate 1, and the two buttons 12 control the management control module 3 and the air pump 41, respectively.
According to the application, the microwave plasma furnace is used for ignition without an electrode, so that the ablation of flame on the electrode is reduced, and the service life of the furnace is longer. In addition, the microwave plasma furnace does not need larger transformer equipment to provide high voltage when in use, and occupies smaller volume space and is convenient to carry. The microwave plasma furnace can realize ignition by only 1kW-3kW, can rapidly generate high-temperature (about 2000 ℃) flame, has small energy consumption, and is more energy-saving and environment-friendly.
