[0002] One existing method for preparing hypochlorous acid disinfectant involves delivering a stock solution, water, and carbon dioxide to a gas-liquid mixing module. The stock solution, water, and carbon dioxide are mixed in the gas-liquid mixing module to prepare hypochlorous acid disinfectant. CN2021108459985 discloses a liquid-gas mixing device and its mixing method, in which water enters through a water inlet channel, and the stock solution enters through a stock solution channel. After the water and stock solution are mixed, they are mixed with carbon dioxide entering the gas channel to prepare hypochlorous acid disinfectant.

Detailed Implementation

[0024] The present invention will now be described in conjunction with the accompanying drawings and embodiments.

[0025] As shown in the attached figure, a hypochlorous acid disinfectant generating device includes a generating tank 1. The generating tank 1 has a raw liquid inlet 1011, a gas inlet 1012, a water inlet 1021, a liquid outlet 1013, and a vent 1022. In this embodiment, the generating tank 1 includes a tank body 101 and a tank cover 102. The tank cover 102 is placed on the tank body 101 and is detachably fixed to the tank body 101 by fasteners. A sealing ring is installed at the connection between the tank cover 102 and the tank body 101 to ensure the airtightness of the generating tank 1. In this embodiment, the detachable connection between the tank body and the tank cover is achieved by bolts and nuts. Alternatively, the connection between the tank body and the tank cover can be achieved by welding and then further tightened by bolts and nuts.

[0026] The gas inlet 1012, the raw liquid inlet 1011, and the liquid outlet 1013 are located at the bottom of the tank 101. The gas inlet 1012 is located at the bottom of the tank 101 so that carbon dioxide can dissolve better in the generating tank, resulting in higher carbon dioxide solubility and ensuring a good sterilization and disinfection effect of the hypochlorous acid disinfectant. The liquid outlet 1013 is located at the bottom of the generating tank for easy drainage. Alternatively, the gas inlet 1012 and the raw liquid inlet 1011 can be located on the lower side of the tank 101 as needed.

[0027] A liquid outlet solenoid valve 302 is installed at the liquid outlet 1013. The liquid outlet solenoid valve 302 is connected to the controller and is used to control the liquid outlet flow. The generating tank is equipped with a liquid inlet check valve 401 at the raw liquid inlet 1011, an air inlet check valve 402 at the gas inlet 1012, and a water inlet check valve to prevent the backflow of raw liquid, water, and gas. In this embodiment, the gas inlet 1012 is connected to the carbon dioxide cylinder via the air inlet pipe 902. The carbon dioxide cylinder is equipped with a drive mechanism for controlling the gas flow, and the drive mechanism is connected to the controller. The raw liquid inlet 1011 is connected to the outlet of the raw liquid injection pump via the raw liquid inlet pipe 901. The inlet of the raw liquid injection pump is connected to the raw liquid storage tank. The injection pump is connected to the controller.

[0028] In this embodiment, the gas flow is controlled by installing a solenoid valve on the carbon dioxide cylinder, but the method of implementation is not limited to this.

[0029] A water inlet 1021 and an exhaust vent 1022 are located on the top of the tank cover 102. An exhaust solenoid valve 303 is installed at the exhaust vent 1022 and is connected to the controller. In this embodiment, a silencer is also installed at the exhaust vent 1022 to eliminate exhaust noise. A water inlet solenoid valve 301 is installed at the water inlet 1021 and is connected to the controller. The cooperation of the exhaust vent 1022 and the exhaust solenoid valve 303 allows the generator tank to discharge gas when water or raw liquid is introduced.

[0030] A pressure sensor is installed on the generating tank; the pressure sensor is used to detect the pressure in the generating tank. When the pressure in the generating tank reaches the set value, the controller controls the stop supply of gas to the generating tank; in this embodiment, the pressure sensor 7 is installed on the top of the tank cover 102 and is connected to the controller.

[0031] A safety valve 8 is installed on the top of the generating tank. In this embodiment, the safety valve 8 is installed on the tank cover 102. When the pressure sensor 7 fails, the pressure in the generating tank is too high and can be released through the safety valve 8 to ensure the safety of the equipment.

[0032] In this embodiment, the position of the water inlet hole 1021 on the tank cover 102 corresponds vertically to the position of the raw liquid inlet hole 1011 at the bottom of the tank body 101. A water inlet pipe 104 is connected to the water inlet hole 1021. The water outlet end of the water inlet pipe 104 extends to the bottom of the generating tank and is located above the position of the raw liquid inlet hole 1011. The vertical correspondence between the position of the water inlet hole 1021 and the position of the raw liquid inlet hole 1011 allows the water inlet pipe 104 to be a simple straight pipe, enabling water to reach the position of the raw liquid inlet hole 1011 along the water inlet pipe 104. The matching of the position of the water outlet end of the water inlet pipe 104 and the position of the raw liquid inlet hole 1011 ensures that the water entering the generating tank can be directly and fully mixed with the raw liquid entering the generating tank, ensuring a good preparation effect of hypochlorous acid disinfectant.

[0033] The bottom of the tank 101 is fixed with spaced-apart partitions 103 along the circumference of the raw liquid inlet 1011. A water outlet channel 105 is formed between adjacent partitions 103. The water outlet end of the water inlet pipe 104 extends into the space enclosed by the partitions 103. The partitions 103 facilitate better mixing of water and raw liquid.

[0034] In this embodiment, the enclosure 103 is an arc-shaped plate with its opening facing the original liquid inlet 1011, and the spaced enclosures 103 form a cylindrical structure that wraps around the water outlet of the water inlet pipe 104.

[0035] The generating tank is equipped with a liquid level detection sensor, which includes an upper limit liquid level sensor 201, an upper liquid level sensor 202, and a lower liquid level sensor 203. The upper limit liquid level sensor and the upper liquid level sensor are installed on the upper side wall of the tank body, with the upper limit liquid level sensor positioned above the upper liquid level sensor. The lower liquid level sensor is installed at the bottom of the tank body. The upper limit liquid level sensor 201, the upper liquid level sensor 202, and the lower liquid level sensor 203 are respectively connected to a controller for detecting the liquid level in the generating tank. In this embodiment, the upper limit liquid level sensor 201, the upper liquid level sensor 202, and the lower liquid level sensor 203 are photoelectric sensors.

[0036] The generating tank 101 is equipped with a pH meter 5 and an available chlorine sensor 6. The pH meter 5 and the available chlorine sensor 6 are respectively connected to the controller. The pH meter 5 is used to detect the pH value of the hypochlorous acid disinfectant prepared in the generating tank, and the available chlorine sensor 6 is used to detect the available chlorine content of the hypochlorous acid disinfectant prepared in the generating tank.

[0037] In this embodiment, the controller is either an MCU-based controller or a PLC controller.

[0038] In this embodiment, the size and capacity of the generated tank can be flexibly selected according to usage requirements.

[0039] When using this utility model: 1. When preparing hypochlorous acid disinfectant, the controller closes the outlet solenoid valve 302, opens the exhaust solenoid valve 303, opens the water inlet solenoid valve 301, and starts the injection pump. Water flows into the generating tank 1 through the water inlet 1021, the water inlet check valve, and the water inlet pipe 104. The injection pump draws the original liquid from the storage tank and pushes it into the generating tank 1 through the original liquid inlet pipe 901, the water inlet check valve 401, and the original liquid inlet 1011. The water at the outlet of the water inlet pipe 104 mixes with the original liquid at the bottom of the generating tank 1. The gas in the generating tank 1 is discharged through the exhaust port 1022. When the liquid level in the generating tank reaches the position of the upper liquid level sensor 202, the controller closes the water inlet solenoid valve 301, closes the exhaust solenoid valve 303, and stops the injection pump. 2. The controller controls the drive mechanism on the carbon dioxide cylinder to open the carbon dioxide cylinder. High-pressure carbon dioxide enters the generating tank 1 through the inlet pipe 902, the inlet check valve 402, and the gas inlet port 1012. The high-pressure carbon dioxide dissolves in the liquid mixture of water and the original liquid. When the pressure sensor 7 detects that the pressure in the generating tank 1 reaches the set value, it feeds the signal back to the controller. The controller controls the drive mechanism on the carbon dioxide cylinder to close the carbon dioxide cylinder and stop the gas supply. The pH meter 5 detects the pH value of the liquid in the generating tank 1 and feeds it back to the controller. The available chlorine sensor 6 detects the available chlorine content in the generating tank 1 and feeds it back to the controller. 3. When liquid needs to be collected, the controller controls the liquid outlet solenoid valve 302 to open, and the prepared hypochlorous acid disinfectant solution flows out from the liquid outlet hole 1013; 4. When the liquid level sensor 203 detects no liquid, the controller controls the generating device to start liquid production again.
