Detailed Description
The embodiments are described in detail in connection with the above drawings,
the embodiment of the invention is as follows: a low-temperature plasma atomization double killing device comprises a frame 1 and a conveying roller 2, wherein the frame is positioned above the conveying roller, an inlet 3 and an outlet 4 are respectively arranged at two ends of the frame, an atomization area 5 is arranged at the inlet of the frame, and an atomization device 6 and a spray head communicated with the atomization device are arranged in the atomization area; a low-temperature plasma discharge region 7 is arranged in the position, adjacent to the atomization region, in the rack, a low-temperature plasma discharge device is arranged in the low-temperature plasma discharge region, and an outlet region in the rack is adjacent to the low-temperature plasma discharge region; a control panel 8 and a control button 9 are arranged on the outer side of the frame, and the running speed of the conveying roller, the atomizing device and the low-temperature plasma discharging device are respectively controlled by a PLC circuit;
the atomization device is an ultrasonic atomization device;
a water tank and an oxygen generator 10 are arranged in the frame, the water tank is communicated with a first water pump through a pipeline, the first water pump is communicated with a plasma generator through a pipeline, the plasma generator is communicated with a gas-liquid mixing device through a pipeline, the gas-liquid mixing device is communicated with an ultrasonic atomization device through a pipeline, and the ultrasonic atomization device is communicated with a spray head through a pipeline; the ultrasonic atomization device is additionally provided with a pipeline for collecting residual liquid, and the residual liquid is returned to the water tank through a return pipeline;
the first flow valve is communicated with the plasma discharge device through a pipeline; the oxygen generator is communicated with a second flow valve through a pipeline, and the second flow valve is communicated with the plasma generator through a pipeline;
the structure of the low-temperature plasma discharge device is as follows: a high-voltage driving circuit 17 is arranged in the shell 11, a heat radiating fin 16 is arranged below the high-voltage driving circuit, a boosting coil 12 is arranged above the high-voltage driving circuit, a high-voltage discharging spring 13 is arranged at the top of the shell, a high-voltage discharging needle 14 is arranged at the top of the high-voltage discharging spring, and an oxygen tube 15 is communicated in the high-voltage discharging spring;
and spraying three-proofing paint outside the high-voltage driving circuit.
The working principle of the invention is as follows: the high-concentration oxygen generated by the oxygen generator is adjusted to the required flow through the pipeline flow valve, enters the plasma generator and is ionized through high-voltage discharge to form high-concentration ozone gas. Ozone gas enters a gas-liquid mixing device through a pipeline, and the ozone gas is sprayed into micro bubbles by a gas stone with countless micropores and is fully mixed with tap water to generate ozone water solution with strong oxidizing property. The ozone water solution enters the ultrasonic atomization device through a pipeline to generate water mist, and the water mist is mixed with air and is sprayed out through the spray pipe. Because the quartz tube of the plasma generator needs water cooling for heat dissipation, water of the small water pump needs to absorb heat through the plasma generator and then enters the gas-liquid mixing device.
The sprayed ozone water mist has strong oxidizing property and good killing effect on various bacteria and viruses. The water mist has good adhesive force to the surface of an object, can achieve a continuous killing effect after being attached to the surface of the object, and has obvious superiority compared with the ozone gas killing. And the fog is not left after being volatilized, and the surface of an object cannot be damaged or injured.
And the other path of oxygen from the oxygen generator enters the low-temperature plasma discharge device after being regulated by the flow valve. The discharge device discharges in oxygen with higher concentration to generate low-temperature plasma gas, and has good sterilization and disinfection effects.
The goods box body which is sterilized by ozone water spraying is sterilized for the second time by low-temperature plasma, and the discharge heat of the low-temperature plasma can also accelerate the drying speed of the wet box body. After two times of sterilization, all bacteria and viruses on the surface of the box body are basically killed, and no medicine residue is left.
The sterilizing effect of the ozone water is also acknowledged, and according to the found data, the ozone concentration in the water is kept between 0.1 and 0.5mg/L for 5 to 10 minutes to achieve the aim of disinfection. The ozone water disinfection and sterilization are rapid, and the disinfection effect is generated instantly. Once the concentration of ozone in the clear water is reached, bacteria can be killed within 0.5-1 minute, the concentration reaches 4mg/L, and the inactivation rate of hepatitis B virus within 1 minute is 100%. Herbold reports: under the condition of 20 ℃, when the ozone concentration in water reaches 0.43mg/L, the escherichia coli can be killed by 100 percent, and only 0.36mg/L can be completely killed at 10 ℃. When the concentration of the ozone is 0.25-38 mg/L, the Hepatitis A Virus (HAV) can be completely inactivated in only a few seconds or a few minutes. The ozone solubility in mineral water is 0.4-0.5 mg/L, so that the sterilization and quality guarantee requirements can be met. The reasonable ozone adding amount is 1.5-2.0 mg/L. Considering that ozone itself is easily decomposed, the higher the concentration of ozone water is, the longer the active sterilization can be maintained, and the better the sterilization effect is. According to the data found, at a temperature of 20 ℃ (for example, ozone concentration of 3mg/l in water, half-life of 5-30 min, decomposition speed in pure water is slow, and half-life of 20min in distilled water or tap water.
In order to ensure a good disinfection effect, the ozone concentration in the ozone water, especially the spray, should be increased as much as possible. It was therefore decided to use a method of supersaturation with ozone, i.e. to ensure that the continuous supply of ozone gas is above its maximum saturation in water. Ozone dissolved in water is removed, and the excessive ozone gas and mist are mixed and sprayed to the surface of the object to be killed together, so as to achieve the maximum killing effect.
According to the published information, the ozone density is 2.14g/L (0 ℃, 0.1MPa), the ozone can dissolve 0.494 volume of ozone in a body of water under the standard condition, and the saturation capacity is 1.05g/L after conversion. The water flow of the small water pump entering the gas-liquid mixing tank is 5.8L/min. The oxygen amount of the ozone generator reserved by the oxygen generator is 0.5L/min. Through conversion, if the gas and the liquid can be fully mixed, the concentration reaches 180mg/L which is far higher than the required value, and the killing effect can meet the required value. And part of the un-mixed ozone gas enters the atomization water tank from the gas-liquid mixing tank, and then is mixed with the water mist and sprayed to the surface of the sterilizing object together, so as to ensure the effect.
And two flow regulating valves can be added on the gas path in consideration of the oxygen consumption and the concentration regulation problem of ozone water. One corresponding to the low-temperature plasma discharge coil and the other corresponding to the plasma generator (ozone gas generating device).
The low-temperature plasma discharge part utilizes the high-voltage coil to discharge, ionizes oxygen in the air, generates low-temperature plasma gas with strong oxidizing property, and carries out sterilization treatment on the surface of an object.
The invention adopts two disinfection modes to disinfect and sterilize the surface of the outer package of the article in a double-pipe way. The equipment adopts an industrial oxygen generator to provide pure oxygen of not less than 90 percent for the plasma generator, and active groups such as oxygen atoms and the like ionized by the plasma generator can quickly inactivate viruses and bacteria within 5 to 10 seconds.
The above examples are merely illustrative for clarity and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. It is not necessary or necessary to exhaustively enumerate all embodiments herein, and obvious variations or modifications can be made without departing from the scope of the invention.
