Description

Discharge plasma air sterilization clearing machine
This utility model belongs to disinfection apparatus, particularly a kind of plasma air sterilization clearing machine.
Along with the continuous progress of China's medical skill means, also more and more higher to indoor air quality requirement such as hospital operating room and nursing units.The air ambient of pure and fresh cleaning not only for preventing the postoperative sequela and reducing cross infection and played the important leverage effect, has improved the quality of operation and medical treatment, has improved medical personnel's working environment and patient's treatment environment simultaneously again.
At present, the method and apparatus of domestic operating room sterilization mainly contains: 1, the method for using herbal sprinkling and ultraviolet radiation to combine is carried out sterilization, and the shortcoming of this method is conspicuous.At first be that chemicals has penetrating odor; Secondly, this sterilization method can only be used for terminal disinfection, and can not lasting use the under people's situation arranged.Like this, in operation process, the indoor microorganism concn that has reduced is difficult to keep, and the activity of indoor occupant can make the microorganism concn bounce-back raise, even reaches the level before the sterilization; This besides method is used inconvenience, and duration of efficacy is short.2, adopt ozone machine to sterilize, the shortcoming of this method also is to have people's occasion to use, and ozone can cause corrosion and aging to the rubber position of medical apparatus and instruments in the operating room simultaneously.3, adopt dynamic germicidal machine, its principle be adopt the ozone ultraviolet tube in casing to the air sterilization that circulates.In addition, the minority electrons sterilization machine is arranged also on the domestic market, but these sterilization machines, its sterilization effect can only reach 500cfu/m under current intelligence 3, considerably beyond the 200cfu/m of national Specification 3Following requirement.The Laminar Flow Room cleaning method has overcome above defective, and air purification effect is better, but the disposable input of equipment is very huge, is not suitable for China's national situation.Therefore, have people's occasion how economy save and the control total number of bacteria of continuous and effective, be the focus place of improving the hospital operating room air quality.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides that a kind of germicidal efficiency height, good dedusting effect, cost are low, conveniently moving, the electronic sterilizing device that can use under current intelligence.
For achieving the above object, the technical solution adopted in the utility model is: cabinet of the present utility model surface is provided with air inlet and air outlet, top in cabinet be provided with anion generator and with the corresponding layer that eliminates the unusual smell of air outlet, bottom at the layer that eliminates the unusual smell is provided with heat exchanger and filtering device for filtering extremely fine dust, middle part at cabinet is provided with bactericidal unit, is provided with in the bottom of cabinet and corresponding quiet circulating fan of air inlet and high frequency positive pulse high voltage power supply.
Bactericidal unit of the present utility model is made up of the insulating lid that is arranged on the horizontal multiple formula wire discharge anode in the insulation column, wavy meander formula negative electrode and be arranged on the insulation column.
Horizontal multiple formula wire discharge anode of the present utility model links by negative wire and high frequency positive pulse high voltage power supply by positive wire, wavy meander formula negative electrode.
This utility model utilizes high-frequency and high-voltage positive pulse voltage to produce large-scale stable discharging plasma around wire electrode, forms the plasma immersion effect with killing bacteria.Utilize wavy negative electrode and combined type multistage filtering device to carry out dedusting simultaneously, thereby reach the purpose of high efficiency sterilization and udst separation.
Fig. 1 is a schematic appearance of the present utility model.
Fig. 2 is an internal structure sketch map of the present utility model.
Fig. 3 is the structure chart of discharge plasma bactericidal unit of the present utility model.
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are elaborated.
Referring to Fig. 1,2, bottom at the cabinet 1 that has air inlet and air outlet is provided with universal wheel 9, be provided with and the corresponding quiet circulating fan 7 of air inlet in the bottom of cabinet 1, air enters this utility model by air inlet under the drive of blower fan 7, be provided with high frequency positive pulse high voltage power supply 8 in the bottom of quiet circulating fan 7.Be provided with bactericidal unit 6 at the middle part of cabinet 1, bactericidal unit 6 is provided with filtering device for filtering extremely fine dust 5, the top in cabinet 1 be provided with anion generator 2 and with air outlet corresponding eliminate the unusual smell the layer 3, anion generator 2 can discharge concentration greater than 10 6Individual/cm 3Anion; The layer 3 of eliminating the unusual smell is adsorbable to fall the stink of operating room and the smell of blood etc.; The air of the pure and fresh cleaning after sterilization of process discharge plasma and defecator 5 filter feeds indoor by air outlet, be provided with heat exchanger 4 in the bottom of the layer 3 that eliminates the unusual smell, the inside and outside heat of its energy balance sterilizing machine; Bactericidal unit 6 is made up of wavy meander formula negative electrode 11 and horizontal multiple formula wire discharge electrode 10, wavy meander formula negative electrode 11 has formed the electrostatic precipitation structure, it and filtering device for filtering extremely fine dust 5 and be contained in primary filter device on the air inlet and form combined type three-stage filtration of the present utility model system, thus make efficiency of dust collection improve; On the other hand, horizontal multiple formula wire discharge anode 10 unique on the discharge plasma bactericidal unit is under the effect of high frequency positive pulse high voltage power supply 8, can around electrode, produce large-scale stable discharging plasma, can be caused death by the plasma thorough impregnation by this regional antibacterial, thereby make germicidal efficiency of the present utility model also greatly improve.
Referring to Fig. 3, bactericidal unit 6 is by insulation column 12 and be arranged on wavy meander formula negative electrode 11, horizontal multiple formula wire discharge anode 10, positive wire 14, the negative wire 15 in the insulation column 12 and the insulating lid 13 that is arranged on the insulation column 12 is formed.The both positive and negative polarity of wavy meander formula negative electrode 11, horizontal multiple formula wire discharge anode 12 links with high frequency positive pulse high voltage power supply 8 by positive wire 14 and negative wire 15.Form the plasma discharging tagma and kill bacteria around the horizontal multiple formula wire anode 10.Wavy meander formula negative electrode 11 can be kept discharge, can change airflow direction and absorption fine particle again.The air of band antibacterial is forced to rise from the bactericidal unit bottom under the effect of blower fan, makes sterilizing efficiency improve; Adopt wavy meander formula negative electrode, make ascending air be obstructed, change its airflow direction, grit is adsorbed, and therefore effectively raises sterilization and efficiency of dust collection.
This utility model can improve the air quality in places such as hospital operating room, delivery room, burn ward, asthma ward, lazaretto ward greatly, reduces the malpractice that causes because of bacterial infection.It will be improve China's level of medical and health, guarantees that people are healthy, improves medical institutions' economic benefit and social benefit and produces great influence.
