Description

Technical Field

[0001] The utility model relates to the technical field of disinfection and sterilization equipment, in particular to a gas chlorine dioxide disinfection device used for disinfecting equipment and utensils in a certain space. Background Art

[0002] Chlorine dioxide gas is internationally recognized as an efficient and safe oxidant that can be used for sterilization, preservation, bleaching, etc. The World Health Organization classifies it as sanitary safety level A1. It can kill most microorganisms, including bacteria, fungi, mycobacteria, viruses and bacterial spores, achieving high-level disinfection to sterilization. The disinfection activity is not affected by pH value, and these microorganisms are not easy to develop resistance.

[0003] Chlorine dioxide gas is unstable and easily reduced, exploded, and photolyzed, so it is mostly obtained by on-site preparation before being used for disinfection. Heating reaction reagents can produce chlorine dioxide gas, which can be used to disinfect equipment and appliances within a certain space. Many chlorine dioxide gas disinfection devices currently on the market use a single beaker-type reaction chamber. Due to the limitations of reaction conditions, the amount of reagents involved in a single reaction cannot be too large, resulting in a limited total amount of chlorine dioxide gas produced. The reaction chambers of most existing disinfection devices are only suitable for room temperature reaction reagents, do not support heating reactions, and do not have a matching gas circulation system and reaction residue cleaning system, making it impossible to achieve continuous and automatic disinfection of the disinfection space.

[0053] The working principle of a gas chlorine dioxide disinfection device of the utility model for disinfecting equipment in a disinfection space is as follows:

[0054] First, unscrew the reaction chamber cover 25 above the first glass 19 or the second glass 20, pour the reaction reagent into it, and then operate the corresponding button on the touch screen when the device is turned on to start the reaction program, and the heating sleeve 18 of the corresponding first glass 19 or the second glass 20 starts to heat. The fan 28 starts to start, and when the temperature sensor 26 feedbacks that the heating reaches a certain temperature, the reaction reagent reacts, and gaseous chlorine dioxide begins to be generated, and enters the disinfection space along the wind flow formed by the fan 28 for disinfection for a certain period of time. The reaction of the first glass 19 and the second glass 20 can be carried out separately or simultaneously.

[0055] In the above reaction, the wind flow direction is as follows:

[0056] When the fan 28 is started, the generated air flows through: the air outlet of the fan 28 is connected to the air inlet 24 through a hose, then passes through the reaction chamber air duct 27 and the 3 air outlets of the reaction chamber assembly, reaches the ventilation flange connector 36, and the bellows 30, and is connected to the disinfection space through the air outlet connector 31 of the bellows 30 and the hose. The disinfection space is not shown in the drawings, and the air outlet connector 31 is directly connected to the disinfection space through a corrugated hose.

[0057] The direction of the return air generated is as follows:

[0058] The return air generated in the sterilization space flows back to the return air connector 32 through the hose. The sterilization space is not shown in the drawings, and the return air connector 32 is directly connected to the sterilization space through the corrugated hose. The return air connector 32 is connected to the bellows 30, and returns to the fan 28 through the bellows 30 and the fan return air duct 29, so as to generate internal and external circulation of the entire air path.

[0059] The cleaning working principle of a gas chlorine dioxide disinfection device of the utility model is as follows:

[0060] First, open the clean water tank cover 12 and inject enough water into the clean water storage tank 14. If the clean water storage tank 14 is short of water, the clean water tank liquid level sensor 15 will feedback a low liquid level alarm, and the buzzer will sound an alarm to prompt. When the corresponding button is clicked on the touch screen, the process of flushing and cleaning the remaining reactants in the first glass 19 or the second glass 20 is carried out. When the water level of the first glass 19 or the second glass 20 reaches a certain height, the reaction chamber liquid level sensor 21 will provide liquid level feedback and stop injecting. The heating sleeve 18 is heated to a certain temperature and maintained for a certain dissolution time, and then all the waste water in the first glass 19 or the second glass 20 is discharged into the waste liquid tank 45. When the waste liquid tank liquid level sensor 35 detects that the waste liquid tank 45 is full, the buzzer will prompt, and the touch screen interface will give a prompt message that the waste liquid tank 45 is full, and the waste liquid is stopped. Only after the waste liquid tank 45 is emptied, the drainage work can be continued after clicking the corresponding button on the touch screen. After the drainage is completed, the cleaning process is completed.
