Description
Technical field
The utility model relates to field of disinfecting equipment, is specifically related to a kind of ozone disinfection system.
Background technology
The 55 article, " GMP " (98 years) regulation: " toilet (district) should regularly sterilize ".Wherein disinfectant must not pollute production machine and product.In usual design, the normal method adopting Ultraviolet radiation and chemical agent to fumigate carries out sterilization to workspace.But actual use in exist Ultraviolet radiation less than " dead angle ", and increase with service time, its sterilization capability is constantly decayed; The chemical reagent suffocating sterilization time is relatively long, also needs again to clean clean area and equipment after having fumigated, and easily forms residual and secondary pollution.
Ozone (0
3) be a kind of light blue gas having off-odor, be universally acknowledged highly effective bactericide with broad spectrum, this mainly has very strong oxidability due to ozone, and under finite concentration, ozone can kill rapidly the bacterium in water and air.The more important thing is that ozone is reduced into oxygen after sterilization, without any residual and secondary pollution, this is also the prime advantage of ozone technology application.But ozone at normal temperatures and pressures, less stable, can disintegrate be oxygen.Ozone has strong impulse, and sucking excessively has certain harm (non-combustible, pure substance) to health.
Existing ozonizer, mostly is uniset, is not suitable for large-sized workshop and uses.Simultaneously due to after factory building sterilization, remaining ozone concentration is still higher, needs to carry out process and discharges in time, otherwise can cause healthy hidden danger to the follow-up workman entering factory building work.

Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model;
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, 2, specific embodiment described in the utility model is a kind of ozone disinfection system, comprise air-conditioner set 1, ozone generator 2, air draft unit 3, fresh air pipeline 6 is connected with outside described air-conditioner set, described air-conditioner set 3 side is connected with wind pipe 8, and described wind pipe 8 branch is connected with ozone generator 2, is also connected with return air duct 7 above described air-conditioner set 1, described return air duct 7 branch is connected with air draft unit 3, and described air draft unit 3 side is connected with exhaust duct 9;
Described fresh air pipeline 6, return air duct 4 are respectively arranged with control valve, and described ozone generator 2, junction, air draft unit 3 front end are respectively arranged with control valve;
Described air draft unit 3 front end is provided with holey catalysis box 5, and described fresh air pipeline 6 tail end is provided with screen pack 4, and the described return air duct mouth of pipe 7 is provided with screen pack 4.
Due to ozone, there is strong impulse, sucking excessively has certain harm to health, if so in the gas got rid of, ozone content is higher have harm to crowd movable around plant area, being placed with catalyst in described catalysis box 5 is manganese dioxide, lead oxide and platinum.Ozone stable is poor, can resolve into rapidly tasteless nontoxic oxygen under the promotion of catalyst, can harm reduction risk.
As shown in Figure 1, better automatically run for the ease of ozone disinfection system, described air-conditioner set 1, ozone generator 2, air draft unit 3, control valve are also electrically connected with control module respectively.The operation of each unit can be coordinated by control module, control control valve simultaneously, form different gas flow loop.
Because ozonization process is comparatively slow, in order to fully carry out disinfection, need within 1-3 hour in advance, start ozonization work, described control module is also electrically connected with timer.Operator on duty can set disinfecting time section by timer, completes sterilization and air draft work before workman enters factory.
Due to factory building sterilize time, ozone content is very high, can shine into injury to human body, so during sterilization, plant area must strict control, and when having avoided people, carry out disinfection operation, so described control module is also electrically connected with infrared module.Can be given a warning to having the situation of people by infrared module, if alarm is not eliminated, then suspending disinfecting process, start air draft unit and carry out air draft.
Because plant area's area is comparatively large, in order to improve the ozone of high concentration, described ozone generator is high voltage discharge type generator.Such ozone generator uses the high-tension current of certain frequency to manufacture high-voltage corona electric field, makes the oxygen molecule generation electrochemical reaction in electric field or around electric field, thus manufacture ozone.This ozone generator possesses skills the advantages such as maturation, working stability, long service life, ozone output large (unit can reach 1Kg/h)
During use, open Xingfeng capsule valve 10, close return air control valve 11, close air draft control valve 12, open ozone control valve 13, start to pass into ozone in factory building, open return air control valve 11 and the logical ozone loop of part air draft control valve 12 formation subsequently; Enough thick Deng ozone concentration, namely during ozonization, answer 90% and whole air draft control valves 12 of corresponding closedown Xingfeng capsule valve 10, make the whole clean room air be sterilized form inner loop by purification air-conditioning air channel; After 1-2 to be sterilized hour, open whole Xingfeng capsule valve 10 and whole air draft control valves 12, close ozone control valve 13, the row of being formed ozone loop, all discharges the ozone of on-site.
According to the standard of " disinfection technology standard ", for flcating germ in air, ozone sterilization concentration is 2-4ppm, and for the sedimentation bacterium colony of body surface, ozone sterilization concentration is 10-15ppm, (1ppm=2mgm-
3).After other conditions are determined, sterilizing concentration just determines required ozone generating capacity per hour, also affects the time reached needed for ozone sterilization concentration.In addition, the natural half-life of ozone is about 20min, therefore, show that ozone 30-60min reaches desired concn in the design, continue to keep 1-1.51 to carry out disinfection, after adding shutdown 30min, personnel are allowed for access, therefore, ozone generator should open use by 2-31 before per tour work, guarantees its Disinfection Effect and personnel's hygienic requirements.Be used in combination with ozone generator and air-conditioner set in medical plant designing.First suitable ozone generator is selected according to better purifying space and clean level calculation, be placed in the air supply section of air-conditioner set, utilize clean air as the carrier of ozone, make ozone be diffused into each place of toilet rapidly, equably, thus reach the microorganism of clean area is effectively controlled.Meanwhile, air cleaning and conditioning system is played to the effect killing miscellaneous bacteria and mould.Find in practice, ozone can also play to high efficiency particulate air filter the effect that bacteriolyze dredges, and extends its service life.Because density of ozone is greater than air, so wind pipe is positioned at plant area higher position; And return air duct needs to carry out air circulation and waste gas discharge, so exhaust duct is arranged on lower.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
