Description

Technical Field

[0001] The present invention relates to the technical field of chlorine dioxide disinfection, and in particular to a chlorine dioxide disinfection method with human-machine coexistence. Background Art

[0002] During the food production and processing process, it is necessary to inhibit bacterial growth on a daily basis and maintain a sterile environment. At present, most food production workshops use ozone or ultraviolet rays for daily disinfection. Ozone or ultraviolet rays have excellent bactericidal properties, but long-term use of ozone or ultraviolet rays for disinfection may have the following problems: (1) Ozone has extremely strong oxidizing properties. Long-term inhalation may irritate the human respiratory tract and cause certain harm to the human body. Ultraviolet rays generally cannot directly irradiate the human body. Therefore, when using ozone or ultraviolet rays for disinfection, the production space should be unmanned. Since the production space needs to be disinfected regularly or continuously, the sustainable and stable operation of the production workshop cannot be guaranteed; (2) The production workshop is not a static space. During the food production process, there will be dynamic activities such as personnel flow and material transfer. In these scenarios, dynamic flow will inevitably affect the air quality of the production space. Therefore, specific spaces in the production workshop need to be disinfected frequently. Disinfection methods such as ozone disinfection are difficult to use when there are people present. Therefore, traditional disinfection methods reduce production efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0017] In order to make the technical problems, technical solutions and beneficial effects solved by the invention more clearly understood, the invention is further described below with reference to the accompanying drawings and embodiments.

[0018] The present invention provides a chlorine dioxide disinfection method with human-machine coexistence. In an unmanned state, a chlorine dioxide disinfection system is used to perform high-concentration disinfection on a production workshop. At this time, the concentration of chlorine dioxide in the production workshop is 1.5-2ppm; in a manned state, a chlorine dioxide disinfection system is used to perform low-concentration disinfection on the production workshop. At this time, the concentration of chlorine dioxide in the production workshop is 0.3-0.8ppm.

[0019] Chlorine dioxide can achieve coexistence of humans and machines at a concentration of 1ppm. Under low-concentration chlorine dioxide conditions of 0.3-0.8ppm, workers can work in this low-concentration environment for a long time without adverse effects on the human body. In the food production process, especially in dynamic work involving personnel flow, material transfer, etc., low-concentration chlorine dioxide can continuously disinfect the workshop air when people are present without affecting the normal work of personnel. Compared with traditional ozone or ultraviolet disinfection methods, it will not affect production efficiency and is safer.

[0020] During shift changes or breaks, the production workshop can be disinfected at high concentrations, which can not only disinfect the air in the workshop, but also carry out large-scale disinfection of items in the production workshop, which is safe and reliable.

[0021] like Figure 1 As shown, the chlorine dioxide disinfection system includes a controller 1, several sensors 2 for detecting chlorine dioxide concentration, and several movable chlorine dioxide disinfection equipment 3. The controller 1 is electrically connected to the sensors 2 and the chlorine dioxide disinfection equipment 3, dividing the production workshop into multiple production areas. Each production area is equipped with a sensor 2 and a chlorine dioxide disinfection equipment 3. The controller 1 can receive and analyze the data detected by the sensors 2 and promptly transmit the analyzed work instructions to the chlorine dioxide disinfection equipment 3.

[0022] like Figure 2 As shown, the chlorine dioxide disinfection system also includes a chlorine dioxide atomizing spraying system 4, which includes a chlorine dioxide generator 41, an aeration device 42, a vacuum pump device 43, a gas pipeline 44 and an atomizing head 45. The chlorine dioxide generator 41 is used to prepare chlorine dioxide liquid, the aeration device 42 converts the chlorine dioxide liquid into chlorine dioxide gas, the vacuum pump device 43 is arranged between the aeration device 42 and the gas pipeline 44 and is used to deliver the chlorine dioxide gas to the gas pipeline 44, the gas pipeline 44 is arranged on the ceiling of the production workshop, and the atomizing head 45 is arranged on the gas pipeline 44 and is used to spray chlorine dioxide gas downward by atomizing.

[0023] When the production workshop is unoccupied, the chlorine dioxide atomizing spray system 4 performs high-concentration disinfection, while the chlorine dioxide disinfection equipment 3 is idle. When the production workshop is occupied, the chlorine dioxide atomizing spray system 4 is idle, while the chlorine dioxide disinfection equipment 3 performs continuous or intermittent low-concentration disinfection. The chlorine dioxide atomizing spray system 4 is capable of large-scale disinfection of the production workshop, making it more suitable for high-concentration chlorine dioxide disinfection scenarios and facilitating comprehensive disinfection of production spaces and production items. The chlorine dioxide disinfection equipment 3 is mobile, facilitating disinfection of specific areas, providing greater precision and making it more suitable for low-concentration disinfection scenarios.

[0024] like Figure 3-5 As shown, the chlorine dioxide disinfection equipment 3 includes a box body 31 and a feeding box 313. The top of the box body 31 is provided with an air outlet disk 32 and the bottom is provided with an air inlet 33. A blowing device 34 and a chlorine dioxide generating box 35 are fixedly provided in the box body 31. The blowing device 34 is provided below the chlorine dioxide generating box 35 and above the air inlet 33. The chlorine dioxide generating box 35 includes an outer box 36 and a chlorine dioxide reactor 37 fixed in the outer box 36. The top of the outer box 36 is provided with an air outlet 38 and the bottom is provided with an air inlet 39. The blowing device 34 blows air toward the air inlet 39. There are two feeding boxes 313 and they are respectively used to hold chlorine dioxide AB reaction liquids. The feeding box 313 is provided outside the box body 31. The feeding box 313 and the chlorine dioxide reactor 37 are connected by a conveying pipe 314. The conveying pipe 314 is provided with a feeding pump 310 and a solenoid valve 311.

[0025] Specifically, the lower portion of the housing 31 defines an air inlet cavity 316, with an air inlet plate 317 fixed to its top. An air inlet port 33 is located on this plate. The feed pump 310 and solenoid valve 311 are activated, and the chlorine dioxide and chlorine dioxide reaction liquids A and B are fed into the chlorine dioxide reactor 37 to react and produce chlorine dioxide gas. Air enters the housing 31 through the air inlet 33, and a blower 34 blows air toward the air inlet 39. This air enters the outer housing 36, carrying the chlorine dioxide gas out of the air outlet 38 and ultimately out of the air outlet plate 32, where it is dispersed into the production area.

[0026] An outer box 36 is fixed within the housing 31, and a chlorine dioxide reactor 37 is fixed within the outer box 36. A chlorine dioxide gas outlet valve is provided at the top outlet of the chlorine dioxide reactor 37. A gap 318 is provided between the side walls of the chlorine dioxide reactor 37 and the side walls of the outer box 36. A gap 318 is also provided between the bottom wall of the chlorine dioxide reactor 37 and the bottom wall of the outer box 36. An air outlet 312 is provided on the top surface of the outer box 36, and the air outlet 312 is located at the top of the side wall gap 318.

[0027] Chlorine dioxide gas is released from the air outlet 38, while the wind blown into the air inlet 39 from the blowing device 34 passes through the gap 318 and is blown out of the air outlet 312. Due to the narrow space of the gap 318, the air flow increases when it is blown out of the top air outlet 312. This part of the air flow merges with the chlorine dioxide gas at the top in the intersection chamber 315. The two winds have different flow rates, and when they merge, the gas is agitated, which makes it easier for the chlorine dioxide gas to flow out of the air outlet plate 32 and be sprayed near the box body 31.

[0028] A convergence cavity 315 is provided at the top of the box body 31, and the convergence cavity 315 is provided between the top of the outer box 36 and the air outlet plate 32. The air outlet plate 32 includes a plate seat 321 and a plurality of air outlet holes 322. The plate seat 321 is fixed to the top of the box body 31, and the plurality of air outlet holes 322 are scattered outward along the center of the plate seat 321.

[0029] When the production workshop is occupied, the chlorine dioxide atomizing spray system 4 is at rest, and the sensor 2 monitors the chlorine dioxide concentration in the production area in real time and transmits the concentration data to the controller 1. The controller 1 thereby controls the supply of the chlorine dioxide AB reaction liquid into the chlorine dioxide reactor 37 and further controls the release rate of chlorine dioxide by controlling the chlorine dioxide gas outlet valve. A concentration sensor 2 can be set in the intersection chamber 315 to monitor the release concentration of chlorine dioxide gas in real time.

[0030] Since the work content of each production area is different, the air quality of the space also changes differently under dynamic influences. Therefore, a predetermined concentration range needs to be set for each production area to adapt to different disinfection scenarios. When the concentration sensor 2 detects that the actual concentration of chlorine dioxide is less than the predetermined minimum concentration, the chlorine dioxide reactor 37 starts working. The chlorine dioxide reactor 37 generates a pulsed chlorine dioxide reaction. By controlling the supply of the AB reaction liquid in the chlorine dioxide reactor 37, the amount of chlorine dioxide generated is controlled. When the concentration sensor 2 detects that the actual concentration of chlorine dioxide is within the predetermined concentration range, the chlorine dioxide reactor 37 stops working.

[0031] The controller 1 determines the consumption of chlorine dioxide by analyzing the total reaction time of the chlorine dioxide reactor 37. The controller 1 can be equipped with a display screen and an alarm, etc., to display the gas indicators of each production area in real time, and to alarm when the chlorine dioxide is consumed or about to be consumed, to remind the staff. At the same time, when the actual concentration value detected by the concentration sensor 2 is continuously lower than the predetermined minimum concentration value within a specific period of time, the controller (1) will sound an alarm.

[0032] The present invention realizes differentiated disinfection of production workshops by setting up a chlorine dioxide disinfection system. When there is no one, the chlorine dioxide disinfection system is used to perform high-concentration disinfection on the production workshop. When there are people, the chlorine dioxide disinfection system is used to perform low-concentration disinfection on the production workshop. The low-concentration chlorine dioxide can continuously disinfect the workshop air when there are people, without affecting the normal work of personnel. Compared with traditional ozone or ultraviolet disinfection methods, it realizes the coexistence of man and machine, does not affect production efficiency, and is safer.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should fall within the scope of protection of the present invention.
