What is the disinfection effect of a spray air shower?
What is the disinfection effect of a spray air shower?The disinfection effect of spray disinfection air shower is usually relatively significant, and it can play a good killing effect on a variety of microorganisms. The following aspects are analyzed:Advantage of the disinfection principle The sterilization effect of disinfectant: The disinfectant used in spray disinfection air showers generally has broad-spectrum sterilization characteristics, such as chlorine disinfectant, hydrogen peroxide, and so on. Chlorine-containing disinfectant can denature bacterial protein and destroy bacterial enzyme systems, to achieve the purpose of sterilization. Hydrogen peroxide can attack the cell membrane and nucleic acid of microorganisms by decomposing hydroxyl free radicals, making them inactive. These disinfectants can effectively kill bacteria, viruses, fungi, and other microorganisms. Spray uniformity: The spray system is well designed, and the nozzle can atomize the disinfectant evenly into small particles, forming a uniform disinfection fog field in the air shower room. Taking the air shower room volume of 10 cubic meters as an example, under the normal spray pressure and flow rate, the disinfectant can be evenly distributed in the entire space within 1 minute, ensuring that the surface of the sterilized object can be exposed to the disinfectant, thus improving the comprehensiveness and effectiveness of disinfection. The synergistic effect of air shower and spray Enhance the contact effect: The high-speed air flow generated by the air shower system, on the one hand, can make the atomized disinfectant better contact with the surface of the object, and on the other hand, can promote the disinfectant to penetrate the hidden parts such as crevices and corners more quickly. For example, when disinfecting goods with gaps, the airflow of the air shower can blow the disinfectant into the gaps and kill the microorganisms hidden in them, which is difficult to achieve such an effect with simple spray disinfection. Improve the efficiency of air purification and disinfection: in the process of air shower, the air is filtered by the initial effect and high efficiency filter, remove the dust particles in the air, reduce the carrier of microbial attachment, and spray disinfection and kill the microorganisms in the air, the combination of the two greatly improves the purification and disinfection effect of the air. In general, after spray disinfection air shower treatment, the number of microorganisms in the air can be reduced by more than 90%. Practical application effect verification Microbial test data: In the practical application of pharmaceutical, medical, and other industries, the surface microbial test results of people and items treated by spray disinfection air shower show that the total number of bacteria, mold yeast, and other indicators are significantly reduced. For example, after the spray disinfection air shower is installed at the entrance of the clean workshop of a pharmaceutical factory, the hands of the personnel entering the workshop are tested for microorganisms. The average bacterial count per square centimeter before disinfection is 100CFU (colony forming unit). After the spray disinfection air shower treatment, the average bacterial count per square centimeter is reduced to less than 10CFU, and the disinfection effect is significant. Infection control effect: In hospitals and other places, the use of spray disinfection air showers to disinfect people and items entering high-risk areas such as operating rooms and intensive care units can effectively reduce the incidence of cross-infection. According to statistics, the postoperative infection rate in a hospital operating room was 3% when the spray disinfection air shower was not used, and the postoperative infection rate was reduced to less than 1% after the spray disinfection air shower. Factors influencing disinfection effect Disinfectant concentration: Disinfectant concentration is too low to effectively kill microorganisms; If the concentration is too high, the object to be disinfected may be damaged, and security risks exist. Different microorganisms have different degrees of tolerance to the concentration of disinfectant. For example, killing Bacillus requires a relatively high concentration of chlorine-containing disinfectant, and the effective chlorine content should generally reach 1000 mg/L or more. Disinfection time: The disinfection time is too short, the contact time between disinfectant and microorganisms is insufficient, and it is difficult to achieve the ideal disinfection effect. Usually, the disinfection time of the spray disinfection air shower room is set between 30 seconds and 2 minutes, and the specific time needs to be adjusted according to the actual situation. Ambient temperature and humidity: Ambient temperature and humidity also have a certain impact on the disinfection effect. In general, when the temperature is 20 ° C to 40 ° C and the humidity is 60% to 80%, the disinfection effect of the disinfectant is better. The temperature is too low or the humidity is too high, which may affect the volatilization and penetration of the disinfectant, reducing the disinfection effect. |
