Description

Ozone vacuum sterilizing bag

Technical Field

The utility model relates to the technical field of disinfection, in particular to an ozone vacuum disinfection bag.

Background

Ozone is a strong oxidant, and its strong oxidizing property makes it have broad-spectrum sterilization and disinfection performance. Ozone disinfection is generally divided into gas phase and liquid phase disinfection. It is now common in the industry to aerate water with high concentrations of ozone to treat drinking water. The killing action of gas-phase ozone on object surfaces is less studied than liquid-phase, but several studies have demonstrated (gas-phase ozone can have a good killing action on a variety of pathogens on the surfaces of a variety of materials under certain conditions, ozone as a gaseous disinfectant has attracted much attention during new corona conditions, before the research on the feasibility of regular ozone disinfection, people have independently tried to introduce the gas of an ozone generator into a container (a heat-proof plastic bag or a storage box) to disinfect objects such as a mask in the container, but the ozone concentration in the whole process cannot be guaranteed, in addition, large-area fabrics are generally folded and placed to save space during ozone disinfection, and the ozone concentration in the folded fabrics (rolled towels) is slowly increased, so that incomplete disinfection in the fabrics is possible.

The prior art discloses the application numbers as: 201710531264.3A vacuum ozone disinfection system for treating exhaust gases. A disadvantage of the prior art is that there is no control of the temperature and humidity during the sterilization process, which may directly result in a significant increase of the CT-value required for reliable sterilization. Sterilization may also be completely ineffective in dry conditions (ambient temperature, humidity < 40%). The prior art also directly relies on ozone generators within its own structure, however there are already a large number of separate ozone generators on the market designed for water treatment/air disinfection, and there is also a need in the market for separate ozone generators to disinfect goods. The ozone generator inside the prior art structure cannot disinfect objects in other devices, which is a bad influence on the cost performance of the ozone generator. Compared with the gas preheating and catalytic decomposition technology, the energy consumption of the thermal decomposer in the prior art is much higher. In addition, the flow rate of ozone rushing into the vacuum bag in the prior art directly affects the flow rate of air in the ozone generator, which causes the concentration of ozone to be reduced when the flow rate of gas in the ozone generator is high, thereby having an adverse effect on the sterilization effect

In summary, the absence of temperature and humidity control during the prior art sterilization process may directly result in a significant increase in CT values required for reliable sterilization, and in dry conditions (room temperature, humidity < 40%) sterilization may be completely ineffective, and furthermore the internal ozone generator may not be able to sterilize the articles in other devices, and the flow rate of ozone into the vacuum bag directly affects the flow rate of air in the ozone generator, which may result in a decrease in ozone concentration when the gas flow rate in the ozone generator is high, thereby adversely affecting the sterilization effect.

2) starting a heating sheet 1203 of the ozone-resistant storage bag 12, and then starting to raise the temperature of the fabric in the vacuum bag 1202; 3) starting all preheating and drying pipes 7 and reaching a preset temperature; 4) ensuring that the air valve 9 between the air storage bag 4 and the ozone-resistant storage bag 12 is closed, starting the ozone generator, and at the moment, because the air valve 9 is in a closed state, ozone gas does not enter the vacuum bag 1202 but gradually fills the air storage bag, and redundant gas after the air storage bag is filled can be automatically treated by the ozone destruction container 8 and then is discharged; 5) starting a vacuum pump 11 to vacuumize the vacuum bag 1202; 6) observing the barometer 10, when the negative pressure reaches the target air pressure and the gas storage bag has enough ozone gas, closing the vacuum pump 11 and opening the gas valve 9, and at the moment, the ozone can quickly flow into the fabric in the vacuum bag 1202 from the gas storage bag under the pressure difference; 7) Repeating the steps 4) and 6) after the vacuum bag 1202 is completely aspirated until the required number of steps is reached, the pre-heated drying tube being set at a temperature of 30 ℃ to 110 ℃.

In use, it is assumed that a cotton towel is to be sterilized, the cotton towel having an area of 70cm by 140cm and a volume of 9792cm³. When the air valve 9 is opened, ozone quickly flows into the vacuum bag 1202, the ozone is fully contacted with the fabric in the vacuum bag 1202 and decomposed on the surface of the fabric, redundant gas enters the ozone destruction container 8 after being heated by the drying pipe 7 and is decomposed into oxygen under the catalytic action of the catalyst, the environment is prevented from being polluted after being exhausted, the check valve 13 can prevent the gas pumped by the vacuum pump 11 from flowing back into the gas storage bag 4 to influence the concentration of the ozone in the gas storage bag 4, and when the attenuation constant (K) of the original cotton cloth is 0.214 (ft) and³/ft²min) we can calculate the time required for the vacuum bag 1202 to consume 90% of the ozone dose according to the following equation:

in the formula, A is the area of the towel, and the actual area is larger than the product of twice the length and the width of the towel considering the internal structure of the towel fiber. We introduce a constant α into the formula, when the actual area equals 2 α times the product of the towel length and width. In the above calculation we assume that α is equal to 4.

The decay constant decreases to 0.029 (ft) after the cotton cloth contacts ozone for a certain time³/ft²Min) we can calculate according to the following formula:

meanwhile, we can also roughly calculate the CT value (CT) caused by ozone flowing into the vacuum bag 1202 each time under different attenuation constants_perRound)。

When the attenuation constant (K) of the cotton cloth is 0.214 (ft)³/ft²-min) we can calculate according to the following formula:

when the decay constant drops to 0.029(ft3/ft2-min) after the cotton is contacted with ozone for a certain time, we can obtain by the same calculation:

CT_perRound≈89.0(ppm*min)

from the rough calculation, it can be estimated that in the first several cycles of vacuum-suction of ozone, the next vacuum-suction operation can be performed only by waiting about 3 seconds after ozone is put into the vacuum-suction device, and the ozone decay constant of the cotton surface is greatly reduced. After the ozone is put into the vacuum-pumping device, the next vacuum-pumping can be carried out after more than 20 seconds, so that the utilization efficiency of the ozone is increased.

In summary, within vacuum bag 1202, the ozone decay constant K for the cotton surface is assumed to be 0.214(ft3/ft2-min) at the onset of ozone contact, to drop and stabilize to 0.029(ft3/ft2-min) after a certain time of exposure to the ozone environment. We can roughly calculate the time (t) required to reach 90% of the total CT value per time in the vacuum bag 1202_90％)。

Assuming that we require that the CT value of the sterilized towel must reach a certain value X (ppm min), the specific operation is as follows with reference to the above calculation results:

1) placing the fabric to be sterilized into the vacuum bag 1202 in the sterilization bag 12, spraying a small amount of water mist, and connecting one end of the air inlet pipe (2) with the air outlet of the ozone generator

2) The internal heating panel 1203 of the sterilization bag 12 is opened, at which time the temperature of the fabric inside the vacuum bag begins to rise;

3) starting all preheating drying pipes 7 and reaching a preset temperature;

4) ensuring that the air valve 9 between the air storage bag 4 and the disinfection bag 12 is closed, and starting the ozone generator, wherein at the moment, because the air valve 9 is in a closed state, ozone gas does not enter the vacuum bag (1202), but gradually fills the air storage bag 4, and redundant gas after the air storage bag 4 is filled can be automatically discharged after being treated by the ozone destruction container 8;

5) starting a vacuum pump 11 to vacuumize the vacuum bag 1202;

6) observing the barometer 10, when the negative pressure reaches the target air pressure and the gas storage bag 4 has enough ozone gas, closing the vacuum pump 11 and opening the gas valve 9, and at the moment, the ozone can quickly flow into the fabric in the vacuum bag 1202 from the gas storage bag 4 under the pressure difference;

7) after the air valve 9 is opened, ozone is flushed into the vacuum bag 1202, meanwhile, the air pressure in the vacuum bag 1202 is rapidly increased to the normal pressure from the vacuumized air pressure, and after the air pressure reaches the normal pressure, the air valve 9 is closed and the vacuum pump 11 is opened to vacuumize the storage bag 4 again after two to three seconds.

8. Step 5 to step 7 are a disinfection cycle. The time during which ozone is retained in the vacuum bag 1202 for each of the first ten cycles (i.e., the time between opening the air valve 9 to return the vacuum bag 1202 to atmospheric pressure and re-evacuation) may be controlled to be 2-3 seconds, and the subsequent sterilization cycle may extend the ozone retention time to 20 seconds. The disinfection cycle was repeated n times, at which time:

12.1(ppm*min)*10+89.0(ppm*min)*n≥X(ppm*min)

during this process the towels within the vacuum bag 1202 are subjected to some moisture and heat, so the absolute humidity per sterilization cycle is greatly increased compared to the ambient temperature. The CT value required to achieve the same sterilization effect as that of the normal temperature environment may be greatly reduced.

To sum up, this ozone vacuum disinfection bag, through the cooperation setting of humidification box 1, intake pipe 2 and outlet duct 3, can guarantee that ozone is in a moist state after humidification box 1 in the in-process of using to guarantee the humidity of ozone in disinfection process, it is poor to avoid humidity low to lead to the fact the disinfection effect, through the setting of heating plate 1203, can heat in the in-process of using, thereby further increase gaseous absolute humidity in order to improve the disinfection effect. This ozone vacuum disinfection bag, it is unrestricted at the entering vacuum bag 1202 in-process flow rate to guarantee ozone through the setting of gas storage bag 4, and can be simultaneously to filling into ozone in the gas storage bag 4 when disinfecting in the vacuum bag 1202 and improve sterile efficiency, more high-efficient reliable, destroy the setting of container 8 through preheating drying tube 7 and ozone, moisture after the drying in-process that can guarantee ozone in the use destroys the catalyst in the container 8 with ozone and contacts, thereby make ozone carry out abundant reaction, it causes environmental pollution to contain ozone in the gas to avoid the combustion.
