Problems solved by technology

[0012] The purpose of the present invention is to overcome the problems of the prior art disinfectants that have adverse consequences and poor disinfection effect of "static disinfection", and provide a microbial control system for clean work areas, through which an ozone generator is introduced into the air outlet duct of a clean air conditioner. Ozone, the concentration of ozone in the work area is monitored by the ozone concentration detector, and the operation of the system is controlled by the controller, which has the advantages of good disinfection effect and convenient use.

Embodiment 1

[0049] 1) After cleaning the equipment and facilities in the clean area, close the fresh air inlet 11 of the clean air conditioner 1, stop the fresh air supply, turn on the ozone generator 2, and send ozone into the air in the clean operation area 6 through the air outlet duct 7 of the clean air conditioner 1 , when the detected value of the ozone concentration detector 4 in each operation area reaches 25ppm, start counting.

[0050] 2) The CT value of ozone disinfection reaches 12000mg / m 3 When min, the ozone generator 2 is stopped, and the fresh air inlet 11 of the clean air conditioner 1 is opened to supplement the clean air processed by the clean air conditioner 1 .

[0051] 3) Through the constant temperature and humidity function of the cleaning air conditioner, the temperature in the cleaning work area is controlled at 25°C and the relative humidity is controlled at 30%.

Embodiment 2

[0053] 1) After cleaning the equipment and facilities in the clean area, close the fresh air inlet 11 of the clean air conditioner 1, stop the fresh air supply, turn on the ozone generator 2, and send ozone into the air in the clean operation area 6 through the air outlet duct 7 of the clean air conditioner 1 , when the detected value of the ozone concentration detector 4 in each operation area reaches 20ppm, start counting.

[0054] 2) The CT value of ozone disinfection reaches 9000mg / m 3 When min, the ozone generator 2 is stopped, and the fresh air inlet 11 of the clean air conditioner 1 is opened to supplement the clean air processed by the clean air conditioner 1 .

[0055] 3) Through the constant temperature and humidity function of the cleaning air conditioner, the temperature in the cleaning work area is controlled at 24°C and the relative humidity is controlled at 15%.

Embodiment 3

[0057] 1) After cleaning the equipment and facilities in the clean area, close the fresh air inlet 11 of the clean air conditioner 1, stop the fresh air supply, turn on the ozone generator 2, and send ozone into the air in the clean operation area 6 through the air outlet duct 7 of the clean air conditioner 1 , when the detected value of the ozone concentration detector 4 in each operation area reaches 30ppm, start counting.

[0058] 2) The CT value of ozone disinfection reaches 14400mg / m 3 When min, the ozone generator 2 is stopped, and the fresh air inlet 11 of the clean air conditioner 1 is opened to supplement the clean air processed by the clean air conditioner 1 .

[0059] 3) Through the constant temperature and humidity function of the cleaning air conditioner, the temperature in the cleaning work area is controlled at 26°C and the relative humidity is controlled at 45%.

Abstract

The invention relates to the technical field of clean production, and discloses a microbial control system of a cleaning operation area. The system comprises a clean air conditioner, an ozone generator, ozone concentration detectors and a controller; the ozone generator feeds ozone into an air outlet pipeline of the clean air conditioner, the ozone concentration detector is arranged in the cleaning operation area, and the controller is in signal connection with the clean air conditioner, the ozone generator and the ozone concentration detector; the invention further discloses a using method ofthe system. The method comprises the following steps that 1), fresh air supplement of the clean air conditioner is closed, the ozone is sent into the cleaning operation area for disinfection throughthe air outlet pipeline, the ozone concentration is kept not less than 10 ppm, and the keeping time is not shorter than 0.5 hour; and 2), the fresh air supplement of the clean air conditioner is started, clean air is sent to the cleaning operation area, the temperature is maintained to be less than or equal to 30 DEG C, and the relative humidity is maintained to be less than or equal to 65%. According to the system, the ozone can be used for carrying out dynamic disinfection on the cleaning operation area, the method is good in disinfection effect, the disinfection condition can be monitored in real time, and the cleanliness requirement of the cleaning operation area can be met.

Description

technical field [0001] The invention relates to the technical field of clean production, in particular to a microbial control system in a cleaning work area and a method for controlling microorganisms in a cleaning work area. Background technique [0002] In GB14881-2013 "General Hygienic Standards for Food Production", based on food quality and safety, the food production environment is standardized, and the food production area is divided into "clean operation area", "quasi-clean operation area" and "general operation area". ", and set clear normative requirements for the microbial conditions in various operating areas. [0003] In the GMP2010 version, based on the characteristics of the drug, the production area is classified into four grades: A, B, C, and D, and the requirements for microbial conditions in each grade are specified. See Table 1 for the sanitation requirements of corresponding grades: [0004] Table 1: Dynamic standards for microbial monitoring in clean ...
