Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.
The embodiment of the invention provides a high-frequency sterilization system, which is characterized by comprising: a material inlet, a sterilizing device and a material outlet; wherein, the sterilizing device comprises a high-temperature heater and an ultraviolet sterilizing lamp for high-temperature sterilization.
The high-frequency sterilization system provided by the embodiment of the invention improves the sterilization efficiency.
Another high-frequency sterilization system provided in an embodiment of the present invention includes: a pulsed magnetic field device 1 and a laser light source device 2; the pulsed magnetic field device 1 is used for generating a pulsed magnetic field; the laser light source device 2 is used for generating pulsed laser light.
The pulse magnetic field and the pulse laser used for sterilization generate a new superposition effect, when the pulse laser passes through the pulse magnetic field, the pulse laser is interfered by the pulse magnetic field, the reflection, the refraction and the scattering of the laser are strengthened, the strong dispersion of the laser is caused, the action range of the laser is expanded, and the inside of the whole sterilization area is filled with magnetic, optical and electric effects. Meanwhile, the laser action accelerates and aggravates the destruction and explosion degree of the cavitation bubbles, the superposition of two kinds of energy is formed, and higher energy is generated, so that the energy is increased compared with the energy of a single magnetic field or the laser action, and the sterilization rate is greatly improved.
The high-frequency sterilization system provided by the embodiment of the invention adopts a mode of sterilizing by combining laser scattering and high-frequency pulse electromagnetic field irradiation, improves the sterilization rate, and is particularly suitable for sterilizing circulating air or flowing liquid; harmful substances are not used in the whole sterilization process, so that the use safety is improved; in addition, the sterilization area is wide, and bacteria in the action area can be thoroughly killed without dead angles.
There are various implementations of the pulsed magnetic field device 1. In order to ensure that the embodiment of the present invention can be applied to various narrow spaces, the embodiment of the present invention provides a preferred implementation manner of the pulsed magnetic field device 1, which includes a control circuit and an RLC circuit, wherein the control circuit is configured to generate a switching signal, and the switching signal is configured to control the RLC circuit to perform charging and discharging, and the control circuit can generate the switching signal meeting the requirement by using a general digital circuit or an analog circuit. Specifically, as shown in fig. 1, the RLC circuit of the pulsed magnetic field device 1 includes a charging circuit and a discharging circuit; the charging circuit is formed by connecting a high-voltage direct-current power supply VCC1, a capacitor C1, a MOS tube Q1 and a resistor R1 in series; the discharge circuit is formed by serially connecting a capacitor C1, a MOS tube Q2, a coil L1 and a resistor R2; the control circuit outputs two switching signals, one signal is input to a grid G1 of a MOS transistor Q1, and the other signal is input to a grid G2 of a MOS transistor Q2.
The operation of the pulsed magnetic field device 1 will now be described. The control circuit sends a high level to the terminal G1, the Q1 is turned on, and the high-voltage direct-current power supply VCC1 charges the capacitor C1 through the R1 current-limiting resistor until the voltage across the C1 is VCC 1. Then, the control circuit sends a high level to the terminal G2, at which time Q2 is turned on and the capacitor C1 is discharged through the coil L0 and the resistor R2 of the transformer T. Because the resistance in the whole discharge circuit is very small, the discharge circuit has strong current, a large magnetic field is generated in the coil L0, and a corresponding magnetic field is generated at the end of the coil L2. The current in coil L0 then charges capacitor C1 again to a value close to voltage VCC1, whereupon the capacitor discharges again in the opposite direction to resistor R2 and coil L0, generating a strong magnetic field in the opposite direction in coil L0 and coil L2. This cycle results in an alternating pulsed magnetic field in coil L2. The pulsed magnetic field device 1 with the structure has the advantages of simple structure and small volume, and is particularly suitable for being applied to places with narrow space.
The principle of sterilization using a pulsed magnetic field is explained below. The inside and outside of each cell membrane have a certain potential difference, under the action of an external magnetic field, the potential difference between the inside and the outside of the membrane is increased, the permeability is increased, the cell permeates, and when the magnetic field reaches a certain value, the cell membrane is irreparably broken. Because the magnetic field generated by the device of the embodiment of the invention is changed, the frequency and the strength of the magnetic field can be greatly changed in a very short time, and an oscillation effect is generated on cell membranes. Irreversible electroporation and intense agitation can cause cell membrane rupture, which leads to disorganization of the cell structure, thereby killing the cells and, in turn, the bacteria.
Table 1 shows the effect of the time interval of the pulsed magnetic field on the sterilization efficiency. As shown in table 1, the shorter the interval time of the pulsed magnetic field, the higher the sterilization efficiency, but the shorter the interval time of the generated pulsed magnetic field, the higher the demand for the pulsed magnetic field device 1, and the larger the volume of the pulsed magnetic field device 1. In order to reduce the volume of the pulsed magnetic field device 1, the interval time of the pulsed magnetic field generated by the pulsed magnetic field device 1 according to the embodiment of the present invention is 0.5 to 5 milliseconds, preferably 1 millisecond.

The operation of the laser light source device 1 will be described below. When the Q3 is turned on, a high-voltage direct-current power supply VCC2 charges a capacitor C2 through R3 until the voltage across C2 is VCC 2; then, when Q4 is turned on, C2 discharges, and a large current is instantaneously generated in the discharge circuit due to a small resistance in the discharge circuit, exciting the LD to generate a pulse laser. In the actual circuit, the existence of inductance is still considered, and L0 is the equivalent inductance of the circuit, so that the discharge circuit forms an RLC oscillation loop, and then a pulse current is generated in the discharge circuit to excite LD to continuously generate pulse laser. The laser light source device 2 with the structure has the advantages of simple structure and small volume, and is particularly suitable for being applied to narrow spaces.
The laser source device 2 generates laser in an infrared band, the preferable wavelength range is 25000-40000 nm, the laser energy in the band is high, and the laser source device can provide higher energy by matching with a pulsed magnetic field, so that the sterilization efficiency is improved.
