[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] Combined with Figure 1-3 The utility model provides a safe hydrogen discharge system for a sodium hypochlorite generator, comprising an electrolytic cell 1 and a tank body 2. The electrolytic cell 1 is connected to the tank body 2 through a drain pipe 11. A blast mechanism 3 is provided on one side of the tank body 2. A flow guide mechanism 4 matched with the blast mechanism 3 is provided inside the tank body 2. An exhaust mechanism 5 is connected to the top of the tank body 2. The blast mechanism 3 comprises a blower 31, a large air duct 32, and a small air duct 33. The lower ends of the large air duct 32 and the small air duct 33 are both connected to the blower 31. The upper ends of the large air duct 32 and the small air duct 33 are respectively connected to one side of the tank body 2 and are distributed up and down. The flow guide mechanism 4 comprises a flow guide plate 41 and a flow guide groove 42. The flow guide groove 42 is located on one side of the tank body 2 and is connected to the small air duct 33. The flow guide plate 41 It is located above the guide groove 42 in the tank body 2 and is connected to the large air duct 32. The guide plate 41 and the guide groove 42 are both located on the opposite side of the drain pipe 11. When in use, the electrolytic cell 1 sends the gas-liquid mixture into the tank body 2 through the drain pipe 11, and the blower 31 sends air to the tank body 2 through the large air duct 32 and the small air duct 33. The air supply volume of the small air duct 33 is small. Since the weight of the solution is greater than that of hydrogen, the air volume flowing out through the guide groove 42 can easily lift the hydrogen, and the solution falls to the bottom of the tank body 2 due to gravity. The lifted hydrogen is quickly discharged from the exhaust mechanism 5 under the influence of the air sent from the guide plate 41 by the large air duct 32. Before the hydrogen is discharged from the exhaust pipe 51, the solution and hydrogen can be effectively separated to avoid waste of resources.

[0024] Embodiment 2

[0025] Combined with Figure 1-3 On the basis of the first embodiment, the exhaust mechanism 5 includes an exhaust pipe 51 and a return pipe 52. The exhaust pipe 51 is connected to one side of the air guide mechanism at the upper end of the tank body 2. The two ends of the return pipe 52 are respectively connected to the exhaust pipe 51 and the tank body 2. The hydrogen is discharged upward through the exhaust pipe 51 under the influence of wind. The influence of wind is weakened at the upper end of the exhaust pipe 51. The solution in the hydrogen will flow back into the tank body 2 from the return pipe 52 under gravity, effectively avoiding the waste of the solution. The exhaust pipe 51 is inclined, and the return pipe 52 is vertically arranged and located at On the opposite side of the guide mechanism 4, the solution in the reflux pipe 52 is less affected by wind. The guide groove 42 includes a ventilation pipe 43 and an air outlet 44. The ventilation pipe 43 is connected to the small air pipe 33. The air outlet 44 is evenly distributed on the inner side of the ventilation pipe 43, so that the wind force supporting the hydrogen is evenly distributed in the tank body 2. The guide plate 41 is inclined toward the upper end of the tank body 2 to facilitate the delivery of hydrogen into the exhaust pipe 51. The upper end height of the drain pipe 11 is lower than the upper end height of the small air pipe 33 to avoid the wind from affecting the normal discharge of the drain pipe 11.

[0026] The working principle of this application is:

[0027] When in use, the electrolytic cell 1 delivers the gas-liquid mixture into the tank body 2 through the drain pipe 11, and the blower 31 delivers air to the tank body 2 through the large air duct 32 and the small air duct 33. The air supply volume of the small air duct 33 is small. Since the weight of the solution is greater than that of the hydrogen, the air volume flowing out through the guide groove 42 can easily lift the hydrogen, and the solution falls to the bottom of the tank body 2 due to gravity. The lifted hydrogen is quickly discharged from the exhaust mechanism 5 under the influence of the air delivered from the guide plate 41 by the large air duct 32. Before the hydrogen is discharged from the exhaust pipe 51, the solution and the hydrogen can be effectively separated. Then, the hydrogen is discharged by rising through the exhaust pipe 51 under the influence of wind. The influence of wind is weakened at the upper end of the exhaust pipe 51, and a small part of the solution still existing in the hydrogen will flow back to the tank body 2 from the reflux pipe 52 due to gravity. The patent effectively reduces the outflow of the sodium hypochlorite solution and the hydrogen mixture during hydrogen discharge, thereby avoiding the waste of resources.

[0028] The above describes the utility model and its implementation methods, which are not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
