The process can avoid the problems of excessive purification and insufficient purification, and stops purification operation when purification is not needed, thereby saving energy consumption and reducing cost.
(4) Air purification:
a. the central controller starts the air pump 8, the air extractor 6 extracts the original air in the operating room, and the air speed is controlled within 20-35L/min;
b. the central controller opens the electromagnetic valve 13, the air discharging device 14 discharges the purified air, and the air discharging speed is controlled within 20-35L/min by controlling the opening degree of the electromagnetic valve 13; pumping and deflating for 20-35min according to the space volume of the operating room;
c. the extracted air is led into an air purifier 9 in sequence and purified for 12-24h according to the volume of the extracted air to obtain purified air;
d. the purified air is delivered into an air compressor 11, compressed and then delivered into a storage 12 for standby.
And (4) circularly and repeatedly purifying the air according to the step (4).
The invention is further illustrated by the following specific examples:
example 1
According to the method, air in an operating room is purified, and various air indexes before air purification are shown in the table 2:
TABLE 2
| Indexes in air | The result of the detection | Each index standard (the critical value is a threshold) |
| Concentration of carbon monoxide | 1346ppm | ≤1000ppm |
| Concentration of carbon dioxide | 78ppm | ≤50ppm |
| Concentration of Formaldehyde | 0.071mg/m3 | ≤0.08mg/m3 |
| Oxygen content | 21.25％ | ≥21.15％ |
| Content of pathogenic bacteria | 2358 pieces/m3 | Not more than 2085 pieces/m3 |
| Humidity | 58％ | 55-60％ |
| Dust particle content | 0.412ml/L | ≤0.348ml/L |
The air indexes after air replacement are shown in table 3:
TABLE 3
It can be seen from table 3 that the air quality of the air purified by the air purifier 9 is significantly improved.
