Pharmaceutical plant application Zhan Kun ozone generator sterilization configuration plan
According to the process characteristics of central air conditioning, it can be divided into centralized centralized air conditioning system, inducer air conditioning system and fan coil air conditioning system. The specific ozone dosing and disinfection method can be selected according to different types of central air conditioners. The central air-conditioning air supply device is used to diffuse the ozone gas produced by the ozone generator through the air supply device of the air-conditioning system (including the fresh air blower) to the entire controlled area, and the ozone gas is mixed into the system by using the air-conditioning duct of the central air conditioner. In the air, the inner circulation is used at the same time to make the ozone concentration in the air uniform. By mixing with the system air, the bacteria, infectious viruses and microorganisms in the ambient air are killed, the quality of the ambient air is improved, and the survival is changed. The health of the person. In the environment where the area to be disinfected is not added any other disinfection equipment, the purpose of sterilization can be achieved, and various viruses and germs can be effectively killed. In practice, it has been found that ozone can also act as a bacteriostatic agent for high-efficiency filters, prolonging their use of odor.
In the purification system of the pharmaceutical industry, the ozone concentration can be used to achieve the concentration requirement in one hour. If it is kept for 0.5-1 hour, the mechanical equipment and the surface sedimentation colony of the building body can be completely killed, completely replacing the chemical fumigation. disinfection.
The pharmaceutical factory, food factory, cosmetics factory and other industries should clearly understand the following articles when selecting the ozone generator of Qinhuangdao Zhankun Disinfection Equipment Co., Ltd .;
How to choose the ozone generator, you must know the evaluation index of the ozone generator. General evaluation of an ozone generator Zui basic indicators are: ozone production, ozone concentration, reliability, service life, power consumption. The ozone generator used in the pharmaceutical factory is relatively small in power, and the power consumption is a secondary condition.
Ozone concentration unit: Internationally used volume percent concentration nominal ozone concentration.
The sanitation and disinfection community is accustomed to use ppm as a unit, that is, one millionth of a volume. For ozone in the air, 1 ppm = 2.14 mg/m3 .
When using the HVAC system for centralized dosing, the ozone generator is selected as follows:
First calculate the actual ozone disinfection volume, the implementation volume consists of three parts V = V1 + V2 + V3 ,
V1 : the total volume of the clean area space,
V2 : the total volume of the air supply duct,
V3 : the volume of the new air volume added to maintain the positive pressure in the clean zone
Determination of each volume:
Qinhuangdao Zhankun Disinfection Equipment Co., Ltd. based on a number of manufacturers using ozone generators to sterilize and sterilize, the more reliable empirical formula is as follows:
V2 is negligible
V3≈HVAC system circulating total air volume m3/h*1.2%
Then determine the cleanliness level of the entire clean plant
According to 2012 zui's new "Disinfection Technical Specifications" and practical application experience
300,000 grades take C=10ppm
100,000 grades take C=20ppm
Take C=30-50ppm
Hundred grades take C=100-200ppm
Floating bacteria in the air: 30-50ppm
Settling colonies on the surface of the object: 100-150ppm
