One embodiment of the present application discloses a method of disinfection. Referring to fig. 1, as an embodiment of the sterilization method, the sterilization method may include the steps of S110-S180:
s110, receiving a disinfection instruction sent by a disinfector;
for example, when a restaurant is disinfected by taking a space to be disinfected as a restaurant and a disinfector as a restaurant manager, the restaurant manager sends a disinfection instruction to the disinfection system, and the disinfector at this moment is the restaurant manager.
S120, preparing chlorine dioxide aerosol for disinfection based on the disinfection instruction;
and after the disinfection system receives the disinfection instruction, chlorine dioxide aerosol for disinfection is prepared, and after the preparation is finished, the chlorine dioxide aerosol is conveyed to a ventilation device which is installed in a restaurant and used for realizing ventilation inside and outside the restaurant, such as a fresh air system or an air conditioning system.
S130, conveying chlorine dioxide aerosol to the space to be disinfected through a ventilation device in the space to be disinfected so as to disinfect the space to be disinfected;
after the chlorine dioxide aerosol enters the air interchanger, the chlorine dioxide aerosol is conveyed into a restaurant by the air interchanger along with the working operation of the air interchanger so as to disinfect the interior of the restaurant.
S140, detecting the concentration of chlorine dioxide gas in the space to be disinfected in real time, and obtaining a first concentration value;
after the chlorine dioxide aerosol enters the restaurant, the concentration of the chlorine dioxide gas in the restaurant is detected in real time, for example, once every second, and the concentration value of the chlorine dioxide gas every second is obtained. In addition, the real-time detection can be carried out when the disinfection system runs, or can be carried out after the chlorine dioxide aerosol enters a restaurant.
S150, judging whether the first concentration value reaches a preset first concentration threshold value, and if so, outputting timing information;
for example, the first concentration threshold may be set to 20ppm, and 20 seconds after the chlorine dioxide aerosol enters the restaurant, the first concentration value reaches 20ppm, and then the timing information is output.
S160, acquiring a first duration of the first concentration threshold value based on the timing information;
and after receiving the timing information, the disinfection system starts timing and acquires the duration of 20 ppm.
S170, judging whether the first time length is larger than a preset first time length threshold value or not, and if so, outputting a stop instruction;
for example, the first time threshold is set to 30min, and when the first time is greater than 30min, the stop instruction is output.
S180, stopping preparing the chlorine dioxide aerosol based on the stopping instruction;
the disinfection system stops dispensing the chlorine dioxide aerosol based on the stop instruction.
Referring to fig. 2, as one embodiment of the step of preparing the chlorine dioxide aerosol for sterilization, steps S121 to S125 may be included:
s121, conveying the chlorine dioxide mother liquor, the chlorine dioxide activating agent and the clear water to a chlorine dioxide activating tank according to a preset ratio to realize the ratio of the chlorine dioxide disinfection liquid;
s122, aerating the proportioned chlorine dioxide disinfection liquid to generate chlorine dioxide gas;
s123, atomizing a pure sodium chloride solution to obtain atomized gas in the process of aerating the chlorine dioxide disinfection liquid;
s124, sequentially carrying out gas-liquid separation and drying on the atomized gas to obtain sodium chloride particles;
and S125, mixing the sodium chloride particles with chlorine dioxide gas to obtain chlorine dioxide aerosol.
In addition, referring to fig. 3, as another embodiment of the sterilization method, the sterilization method may include the steps of S210-S230:
s210, detecting the air intake of fresh air in the ventilation device in real time;
s220, detecting the concentration of the chlorine dioxide disinfection liquid in real time to obtain a second concentration value;
and S230, dynamically adjusting the second concentration value based on the change of the intake air and the change of the first concentration value, so that the dynamic change of the first concentration value is within the range specified by the preset national standard.
When the chlorine dioxide aerosol is used for disinfecting a restaurant, the concentration of chlorine dioxide gas is required and must meet the national standard, so that the concentration of the chlorine dioxide gas in the restaurant is regulated by regulating two parameters, namely the air intake and the concentration of the chlorine dioxide disinfection liquid, so that the change of the concentration of the chlorine dioxide gas is always in the range specified by the national standard. It should be noted that the first concentration threshold is also within the range specified by the national standard.
In addition, referring to fig. 4, a step before step S110 may include steps S101 to S102:
s101, collecting a first face image of a disinfector;
for example, when a restaurant needs to be disinfected, the disinfection system may collect a first facial image of the restaurant manager.
S102, judging whether the first face image is matched with a second face image in a preset face image library or not, and if yes, sending a disinfection command.
The facial image library includes a second facial image of a sterilizer registered in advance, for example, of a restaurant manager, a subway station manager, a hospital manager, or the like. After the first face image of the restaurant manager is collected by the disinfection system, the first face image is compared with all second face images in the face image library one by one, and if the first face image is matched with all second face images in the face image library, the restaurant manager can send a disinfection instruction, so that the disinfection system can receive the disinfection instruction.
Referring to fig. 5, another step before step S110 may include steps S103-S104:
s103, collecting first fingerprint information of a disinfector;
for example, when a restaurant needs to be disinfected, the disinfection system collects first fingerprint information of restaurant managers.
And S104, judging whether the first fingerprint information is matched with second fingerprint information in a preset fingerprint information base, and if so, sending a disinfection instruction.
The fingerprint information base includes second fingerprint information of a sterilizer, such as restaurant managers, subway station managers, hospital managers, and the like, which is previously recorded. After the first fingerprint information of the restaurant management personnel is collected by the disinfection system, the first fingerprint information is compared with all the second fingerprint information in the fingerprint library one by one, and if one fingerprint information is matched with the second fingerprint information, the restaurant management personnel can send a disinfection instruction, so that the disinfection system can receive the disinfection instruction.
In addition, another step before step S110 may further include:
and receiving a disinfection instruction sent by a disinfector through the mobile terminal. The mobile terminal can be an intelligent terminal such as a smart phone, a tablet, a notebook computer and the like. For example, install the APP that is used for controlling disinfection system on the mobile terminal, after mobile terminal passes through modes such as bluetooth and is connected with the controller in the disinfection system, can control disinfection system.
In addition, referring to fig. 6, as another embodiment of the sterilization method, the sterilization method may include the steps of S310-S320:
s310, under the condition that the chlorine dioxide aerosol is input into the space to be disinfected, obtaining a second time length of the first concentration dynamic change;
s320, judging whether the second time length is greater than a preset second time length threshold value or not, and if so, outputting prompt information; wherein the second duration threshold is greater than the first duration threshold.
For example, the second time period threshold may be set to 40min, and if the second time period is longer than 40min, but the first concentration does not tend to be stable yet and still dynamically changes, it indicates that a problem occurs in the disinfection system or the ventilation device; therefore, prompt information is output to prompt restaurant management personnel to check.
The implementation principle of the embodiment of the application is as follows:
under the condition that a space to be disinfected needs to be disinfected, a disinfector sends a disinfection command, a disinfection system receives the disinfection command, then chlorine dioxide aerosol is prepared, and the chlorine dioxide aerosol is conveyed into the space to be disinfected through a ventilation device in the space to be disinfected, so that the space to be disinfected is disinfected;
