Description
Technical Field
The invention belongs to the technical field of radio frequency generators, and relates to a high-power radio frequency resonance generating device.
Background
The radio frequency is a high-frequency alternating electromagnetic wave with a frequency range of 3-300 MHz. The radio frequency bands permitted in the industry are 13.56,27.12 and 40.68 MHz. The frequency is relatively lower than that of the microwave, so that the microwave oven has a deeper penetrating effect on materials. The radio frequency heating is rapid and uniform, and does not require a temperature differential to force heating. The wet area will absorb more rf power than the dry area and excess moisture will be automatically drained from the wet area, thereby making the moisture distribution more uniform. And the rf power is mainly consumed in the load and does not require long warm-up or cool-down times. Power is consumed only when a load is present and is only proportional to the load. The conventional microwave technology has a short wavelength, and thus the industrial application of the microwave is limited to the application of small-sized products. The radio frequency has longer wavelength, so that the radio frequency can penetrate deep into and even penetrate through compact large-size materials, and the radio frequency can be widely applied to large-size products. At higher frequencies (microwaves), the difference between the loss factors of the various products is generally much smaller than at lower frequencies (radio frequencies). Radio frequency has a higher selectivity when heating products with different chemical, physical and morphological characteristics, so that the heat treatment of different materials is easier to control. Although radio frequency and microwave are energy efficient (about 70%), the operating mode and energy reflection phenomena of microwave devices make their overall energy efficiency about 55%, while radio frequency devices are 60-65%. Thus, energy savings of about 10-15% can be achieved using radio frequency devices compared to corresponding microwave devices. In the prior art, the chinese patent application of side output type rf resonance generator and insecticidal and bactericidal device, having an application publication number of CN109921745A of 21/6/2019, discloses a side output type rf resonance generator, comprising: a high-frequency resonant cavity and a vacuum electronic tube box; the vacuum electron tube box is formed by fixing and sealing a vacuum electron tube by adopting an insulating support and an insulating plate and is positioned in the center of the high-frequency resonant cavity; the high-frequency resonant cavity comprises a box body metal shell, a resonant cavity output polar plate, a resonant regulation capacitor polar plate and an output coupling polar plate. Although this document discloses a radio frequency device, it has the disadvantages of low output power, unstable output frequency, and being not applicable to large-sized material products.
