The principle of the specific sterilization device is that firstly, the water outlet nozzle 801 is connected with the water discharge pipe 5, water leaving from the water outlet nozzle 801 enters the inner sleeve 803, because the water outlet nozzle 801 is positioned outside the inner sleeve 803, and a gap exists between the water outlet nozzle 801 and the inner sleeve 803, a negative pressure is formed near water flow, nearby gas is continuously pressed near the water flow, part of the gas is mixed with the water, in the process, part of oxygen is converted into ozone due to the irradiation of an ultraviolet lamp, so that part of ozone is dissolved in the water, and because the ozone can kill bacteria in the water, the bacteria content of the discharged water is reduced.
The sterilization device is equivalent to a circle of airflow (airflow has the trend of flowing water columns) coated outside the water columns, and a layer of ultraviolet rays is coated outside the airflow, so that the sterilization device can sterilize flowing water at 360 degrees without dead angles, and the sterilization is more comprehensive.
In particular, the inner sleeve 803 is made of glass and the outer sleeve is made of metal, so that exposure of ultraviolet rays can be prevented.
As shown in fig. 5 and 6, the inner sleeve 803 is horn-shaped, and the water outlet nozzle 801 is located at one side of the narrow end of the inner sleeve 803, and the outer sleeve is truncated cone-shaped.
Specifically, the inner sleeve 803 is trumpet-shaped, and the water outlet nozzle 801 is located at one side of the narrow end of the inner sleeve 803, so that the water flow (including the air flow) flows from narrow to wide, and the splashing phenomenon generated when the water flow flows out is reduced. The outer sleeve is in a circular truncated cone shape, so that a plurality of water pipes can be connected conveniently.
As shown in fig. 5 and 6, the narrow end of the inner sleeve 803 is provided with a funnel-shaped arc surface.
The funnel-shaped arc surface is arranged to play a role in guiding gas, so that gas can be mixed with water flow, and meanwhile, the dissipation phenomenon of the water flow can be reduced.
As shown in the figure, the denitrification tank 2 is connected with a vacuum pump through a pipeline (the pipeline is positioned above the liquid level).
The vacuum pump is arranged at the top of the denitrification tank 2, so that the denitrification tank 2 is vacuumized at regular time, negative pressure is formed in the denitrification tank 2, nitrogen generated in the reaction process can escape from water conveniently, and the denitrification reaction can be accelerated.
As shown in fig. 1, the dip tube 301 is a ceramic dip tube 301.
The inclined sinking tank is made of pottery clay, so that the inclined sinking pipe 301 has the characteristic of being porous, particles are adsorbed as much as possible, the weight of the whole tank body can be reduced, and the assembly is convenient.
It should be further noted that the arrows in fig. 1 and fig. 4 are schematic flow directions of the water flow.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, which is defined by the claims, and all the modifications and equivalents of the claims, which can be directly or indirectly applied to other related fields, are also included in the scope of the present invention.
