Description
Technical Field
The invention relates to the technical field of air sterilization, in particular to a hydrated plasma generator, an air sterilization device, an air sterilization control system and a control method.
Background
Along with the improvement of living standard, people pay more and more attention to health, and respiratory diseases caused by viruses, bacteria and the like seriously affect the health of human bodies and further influence social development, so that more and more attention is paid to how to kill or purify the viruses and the bacteria in the air. The existing air purification or disinfection technologies mainly comprise:
HEPA technology
HEPA is an abbreviation of High Efficiency Particulate air Filter, is the best High Efficiency Filter material internationally recognized, and is widely applied to places requiring High cleanliness, such as precision laboratories, medicine production, yard research, surgical operations and the like. HEPA is formed by interweaving very fine organic fibers, has strong capture capacity on particles, small pore diameter, large adsorption capacity and high purification efficiency, and has the advantages of good physical stability, wide application, good environmental adaptability, simple module, easy processing, easy installation and the like. However, as the service time of the filter element increases, a large amount of live viruses and germs are attached to the channel of the filter element, the energy consumption is increased when the pore diameter is reduced, and secondary pollution is caused by the attachments; the filter element made of glass fiber can not be degraded, is not environment-friendly, and needs to be replaced regularly, and has large material consumption and high cost.
2. Spraying sterilizing factor into air
The disinfectant or the aerosol is sprayed into the air in a spraying mode, and the disinfectant or the aerosol needs to be sprayed regularly, but people cannot be in the sprayed air environment during spraying, and the man-machine safety can not be achieved.
3. Ozone air sterilizer
The ozone is obtained by simulating a natural ozone generation method, and the strong oxidation characteristic of the ozone can remove toxic substances released by decoration, synthetic boards and paint, kill bacteria and viruses in the air, kill microorganisms bred in carpets, eliminate cold germs and prevent flu. However, ozone also has adverse effects on human bodies, can stimulate mucous membranes of eyes, noses and throats, and has influence on respiratory systems such as bronchus and lungs, and the concentration of ozone is not easy to control, so that the coexistence of human and machine safety cannot be realized.
4. Ultraviolet air disinfection
Ultraviolet rays with proper wavelength can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial organism cells to cause death of growing cells and death of regenerative cells, thereby achieving the effects of sterilization and disinfection. However, excessive ultraviolet rays may cause damage to the skin, eyes, immune system, etc. of the human body, and since the amount of ultraviolet radiation, particularly the amount of radiation at each radiation point, is not easily controlled precisely, coexistence of man-machine safety cannot be achieved.
5. Anion air purification technology
Air is purified and disinfected by utilizing air anions with certain concentration, because the anions are easily adsorbed with tiny pollution particles (the particles are usually positively charged) in the air to form charged large particles which sink on the surface of the ground and the like, so that the air is purified. The negative ions are usually obtained by a high-pressure air ionization technology, but the air ionization voltage is higher and reaches over 10KV, by-products harmful to human bodies, such as nitride, ozone and the like, are easily generated under high pressure, and the coexistence of man-machine safety cannot be realized.
In summary, no air sterilization technology exists at present, which can coexist in man-machine environment, actively sterilize, consume less energy, and have no or less harmful byproducts.
Plasma (plasma), also called plasma, is an ionized gaseous substance consisting of atoms after part of electrons are deprived and positive and negative ions generated after radicals are ionized, and is a macroscopic electrically neutral ionized gas, when the plasma is propagated in air, positive and negative ions or ion groups in the plasma can be kept for a period of time (within a period of several seconds to several minutes) without recombination, and when the positive and negative ions or ion groups of the plasma are compounded, binding energy can be released.

The voltage amplitude of the high-voltage electric signal output by the high-voltage power supply is set to be larger than or equal to 1KV, and the value range of part of the high-voltage electric signal is smaller than the existing air ionization voltage from 7KV to 10KV, so that the generation of hydrated plasma by low-voltage ionization is realized, the energy is saved, and the generation of harmful byproducts can be reduced due to the reduction of the voltage.
The ionization potential interface is changed by the electrode with water attached to the surface, compared with the existing air ionization technology, the ionization voltage is greatly reduced, the cost is reduced, the energy is saved, and meanwhile, harmful byproducts such as ozone, nitride and the like are not generated or are generated less due to the reduction of the ionization voltage; positive and negative ions generated by ionization in the water are brought out through the diffusion effect of the bubbles, and then plasma is formed on the surface of the electrode attached with the water; the output hydrated plasma takes the nano-scale small molecular water mass as a carrier, can reduce the static accumulation of a use environment, prolongs the compounding time of positive and negative ions or ion groups in the plasma, and can inhibit the generation of harmful byproducts such as ozone, nitride and the like.

Specifically, when the high-voltage power supply is a high-voltage pulse power supply, the operation parameter includes at least one of a water replenishing amount of the water replenishing mechanism, a plasma flow rate at the plasma outlet, a plasma concentration at the plasma outlet, a current of the high-voltage pulse, a power of the high-voltage pulse, and a voltage of the high-voltage pulse.
In this embodiment, it is preferable that a parameter boundary that is not allowed to be exceeded is set for each operating parameter, and the adjustment range of each operating parameter is restricted according to the respective parameter boundary.
In a preferred embodiment, in order to improve environmental and climate adaptability, the method for acquiring corresponding control information by combining environmental information and operating parameters comprises the following steps:
step A, if the air temperature and/or the air humidity are/is reduced, the output power of a high-voltage power supply is reduced, the wind speed of a fan is reduced, and/or the water replenishing quantity of a water replenishing mechanism is increased; it is preferable, but not limited to, adjusting the output voltage or current or frequency of the high voltage power supply to adjust the output power of the high voltage power supply. When the air temperature and/or the air humidity are reduced, the air changes to be dry, harmful byproducts are more easily produced in a dry environment, and therefore the harmful byproducts can be reduced by reducing the output power of the high-voltage power supply. The water replenishing amount of the water replenishing mechanism is increased, so that the static accumulation can be reduced, byproducts in compounding can be reduced, and the compounding time of positive and negative ions and ion clusters can be prolonged. The wind speed of the fan 6 is reduced to avoid the increase of static accumulation caused by the over-fast evaporation of water in the hydrated plasma, so that the generation of harmful byproducts and the reduction of the static accumulation can be reduced, and in a low-temperature and dry environment, the air has less water and more dust, and the plasma is more easily compounded, so that the hydrated plasma with lower concentration can also achieve the aim of killing dust, viruses, suspended matters and bacteria.
And step B, if the concentration of ozone and/or the concentration of nitride in the air are increased, the output power of the high-voltage power supply is reduced, the wind speed of the fan is reduced, and/or the water replenishing amount of a water replenishing mechanism is increased. When the concentration of ozone and/or the concentration of nitrides in the air increases, the output power of the high voltage power supply can be adjusted down to reduce the generation of harmful byproducts. The wind speed of the fan can be reduced to reduce the water loss in the hydration plasma, and the water replenishing amount of the water replenishing mechanism is increased, so that the water in the output hydration plasma is increased, because the water molecule groups can inhibit the generation of ozone and nitride and inhibit the accumulation of static electricity.
And step C, if the air temperature and/or the air humidity are increased, adjusting the output power of the high-voltage power supply and/or increasing the wind speed of the fan and/or reducing the water replenishing amount of the water replenishing mechanism. When the air temperature and/or the air humidity rise, the air humidity increases, the difficulty of generating byproducts increases, and a higher plasma concentration is needed to achieve a good killing effect, so that the output power of a high-voltage power supply needs to be adjusted, the plasma concentration needs to be increased, and the conveying distance of hydration plasma needs to be increased. The wind speed of the fan is increased, the moisture content in the hydrated plasma can be reduced, the water replenishing quantity of the water replenishing mechanism is reduced, and the plasma concentration can be improved.
And D, if the concentration of carbon dioxide or VOC or particulate matter in the air is increased, adjusting the output power of the high-voltage power supply and/or increasing the wind speed of the fan and/or reducing the water replenishing amount of the water replenishing mechanism. When the concentration of carbon dioxide or VOC or particulate matter in the air is increased, the resistance of the hydrated plasma in the air is increased, the hydrated plasma can be conveyed farther by increasing the wind speed of the fan, the output power of the high-voltage power supply is increased, the concentration of the plasma can be increased, the water replenishing amount of the water replenishing mechanism is reduced, the concentration of the plasma can be increased, and a better air killing effect is achieved.
In a preferred embodiment, when the high voltage power supply is a high voltage pulse power supply, the pulse frequency control of the high voltage pulse power supply is increased, because the pulse frequency can adjust the mixing degree of positive and negative ions and ion clusters, the killing effect is improved, and corresponding control information is obtained by combining environmental information and operating parameters, including:
if the air temperature and/or the air humidity are/is reduced, all or part of the frequency, the peak voltage and the power of the high-voltage pulse are/is reduced, and/or the wind speed of the fan is reduced, and/or the water replenishing quantity of the water replenishing mechanism is increased.
If the concentration of ozone and/or the concentration of nitride in the air are increased, all or part of the frequency, the peak voltage and the power of the high-voltage pulse is reduced, and/or the wind speed of the fan is reduced, and/or the water replenishing quantity of the water replenishing mechanism is increased.
If the air temperature and/or the air humidity are increased, all or part of the frequency, the peak voltage and the power of the high-voltage pulse are increased, and/or the wind speed of the fan is increased, and/or the water replenishing quantity of the water replenishing mechanism is reduced.
If the concentration of carbon dioxide or VOC or particulate matter in the air is increased, all or part of the frequency, peak voltage and power of the high-voltage pulse is increased, and/or the wind speed of the fan is increased, and/or the water replenishing amount of the water replenishing mechanism is reduced.
If the air temperature and/or the air humidity are reduced or the ozone concentration and/or the nitride concentration are increased, part or all of the frequency, the peak voltage and the power of the high-voltage pulse are reduced, and byproducts are more easily generated in a drying environment, so that the byproducts can be reduced; and/or the water replenishing amount of the water replenishing mechanism is increased, so that the static accumulation can be reduced, byproducts in compounding can be reduced, and the compounding time of positive and negative ions and ion clusters can be prolonged; and/or the wind speed of the fan 6 is reduced to avoid the increase of static accumulation caused by the too fast evaporation of water in the hydrated plasma, so that the generation of byproducts can be reduced, the static accumulation can be reduced, and in a low-temperature and dry environment, the air has less water and more dust, and the plasma is more easily compounded, so that the hydrated plasma with lower concentration can also achieve the aim of killing dust, viruses, suspended matters and bacteria. If the temperature and/or the humidity rises and/or the concentration of the carbon dioxide or the VOC or the concentration of the particulate matters increases, part or all of the frequency, the peak voltage and the power of the high-voltage pulse are increased, and/or the water replenishing amount of a water replenishing mechanism is reduced, and/or the wind speed of the fan 6 is increased. The temperature and/or humidity rise, the air humidity increases, the difficulty of byproduct generation increases, and a good killing effect can be achieved only by using higher plasma concentration, so that part or all of the frequency, peak voltage and power of high-voltage pulse need to be increased.
In this embodiment, to realize the overall effective control, the specific process may be:
step one, a target value is set for the environmental information, the human body is considered to be the safest or the most comfortable in the air environment corresponding to the target value, and the target value of the environmental information can be set artificially.

The operation parameter target value comprises all or part of a water replenishing flow target value of the water replenishing mechanism for the water 2 attached to the electrode 1, a plasma flow velocity target value and a plasma concentration target value of a plasma outlet, a current target value of the high-voltage pulse, a voltage target value of the high-voltage pulse and a power target value of the high-voltage pulse.
Step two, in the whole control system operation process, the following steps are executed in a circulating way: judging the difference between the current environmental information and the target value of the environmental information, and executing the following steps according to the judgment result:
if the current air temperature is lower than the target value of air temperature, and/or the current air humidity is lower than the target value of air humidity, and/or the ozone concentration is greater than the target value of ozone concentration, and/or the nitride concentration is greater than the target value of nitride concentration, then:
the frequency, the peak voltage and the power of the high-voltage pulse are partially or completely reduced, and harmful byproducts are more easily generated in a drying environment, so that the generation of the harmful byproducts can be reduced, and the byproducts are reduced by reducing the frequency, the peak voltage and the power of the high-voltage pulse when the harmful byproducts are excessive;
and/or the water replenishing amount of the water replenishing mechanism is increased, so that the static accumulation can be reduced, the by-products generated during plasma compounding can be reduced, and the compounding time of positive and negative ions and ion clusters can be prolonged;
and/or, the wind speed of the fan 6 is reduced to avoid the phenomenon that the moisture in the hydrated plasma is evaporated too fast to cause the increase of static accumulation, so that the generation of byproducts can be reduced, the static accumulation can be reduced, in a low-temperature and dry environment, the moisture in the air is less, the dust is more, and the plasma is more easily subjected to combined utilization and can kill dust, viruses, suspended matters, bacteria and the like.

adjusting the frequency, peak voltage and power of high-voltage pulse to increase plasma concentration;
and/or reducing the water replenishing amount of the water replenishing mechanism to reduce the water content of the plasma;
and/or increasing the wind speed of the fan 6 increases the kinetic energy of the plasma.
The temperature and/or humidity rise, the air humidity increases, the difficulty of byproduct generation increases, and a good killing effect can be achieved only by using higher plasma concentration, so that part or all of the frequency, peak voltage and power of high-voltage pulse need to be increased.

The wind speed of the fan 6 is changed periodically, and the product of the maximum wind speed and the recombination time of the positive ions, the negative ions and the ion clusters of the hydrated plasma is larger than the distance between the farthest point of the target killing area and the air killing device. The recombination time of the positive ions, the negative ions and the ion clusters of the hydration plasma participating in the calculation can be selected from the average value of a plurality of experiments.
