In order to solve the above problems, referring to fig. 1, the present invention provides a sterilizing apparatus including: a liquid storage container 1, a first disinfection pipeline 2 and a second disinfection pipeline 3. The first disinfection pipeline 2 is connected with the liquid inlet 11 of the liquid storage container 1, a first water injector 21 is arranged on the first disinfection pipeline 2, and the first water injector 21 is used for mixing external disinfection gas with liquid flowing along with the first disinfection pipeline 2. The second disinfection pipeline 3 passes through the outer wall of the liquid storage container 1 and extends to the inner cavity of the liquid storage container 1, the second disinfection pipeline 3 is provided with a second water injector 31, and the second water injector 31 is used for mixing disinfection gas in the liquid storage container 1 with liquid flowing along with the second disinfection pipeline 3.
In detail, the water jet used in the invention can be of a common water jet type, for example, a negative pressure cavity is arranged in the water jet, and the water jet also comprises a liquid inlet, a liquid outlet and a gas inlet, wherein when pressure liquid sequentially flows through the liquid inlet, the negative pressure cavity and the liquid outlet, negative pressure is formed in the negative pressure cavity, and gas can enter the negative pressure cavity through the gas inlet and be mixed with the liquid to flow out through the liquid outlet together. The "first" and "second" in the first water jet 21 and the second water jet 31 are for convenience of distinguishing the setting positions of the two water jets, and the working principles thereof are identical.
The first water jet 21 of the present invention is disposed on the first sterilizing line 2, and the liquid sequentially passes through the liquid inlet and the liquid outlet of the first water jet 21, and the air inlet of the first water jet 21 may communicate with an external device for supplying sterilizing gas, such as an air tank, a gas pipe, etc. The second water jet 31 is arranged on the second disinfection pipeline 3, liquid sequentially passes through a liquid inlet and a liquid outlet of the second water jet 31, a gas inlet of the second water jet 31 is open, and disinfection gas can be supplied by the disinfection gas in the liquid storage container 1.
In operation, the first water jet 21 mixes the external sterilizing gas with the liquid in the first sterilizing line 2, and the mixed liquid continues to flow along the first sterilizing line 2 and enters the liquid storage container 1 through the liquid inlet 11. Since the sterilizing gas is not completely dissolved in the liquid, a small portion of the sterilizing gas is diffused to the top of the liquid storage container 1, the second water jet 31 is located in the liquid storage container 1, and the sterilizing gas diffused in the liquid storage container 1 can be mixed with the liquid in the second sterilizing line 3, and the mixed liquid continues to flow along the second sterilizing line 3 and is discharged into the liquid storage container 1.
According to the disinfection device provided by the invention, the two water ejectors are used for mixing the disinfection gas and the liquid twice, so that undissolved disinfection gas can be reused in time, the dissolution amount of the disinfection gas in water is increased, the filling amount of the disinfection gas at the front end can be reduced, the discharge amount of the unused disinfection gas can be reduced, the utilization rate of the disinfection gas is increased, and the resource waste is reduced.
The above liquid may be water, and the sterilizing gas may be ozone, or a sterilizing gas commonly used in the field of water treatment such as chlorine dioxide and chlorine. Of course, one skilled in the art can also derive from the above description that the disinfection device provided by the present invention is applied to other applications where liquid and disinfection gas are mixed, and the present invention is not limited to the examples.
In one embodiment of the present invention, the flow rates of the first water jet 21 and the second water jet 31 may be 0.1 ton/hr to 1 ton/hr.
Referring to fig. 2, in one embodiment of the present invention, the liquid inlet 11 is located at the bottom of the liquid storage container 1, and the second water injector 31 is disposed at the top of the liquid storage container 1 at a position corresponding to the liquid inlet 11. For example, the second water injector 31 may be disposed above the liquid inlet 11, so that the distance of the sterilizing gas flowing from the liquid inlet 11 to the second water injector 31 may be shortened, so that the second water injector 31 may timely suck and mix the sterilizing gas with the liquid, and the efficiency of sucking the sterilizing gas into the second water injector 31 is improved.
Referring to fig. 2, in one embodiment of the present invention, a flow guide cover 12 is disposed at the bottom of the liquid storage container 1, the liquid inlet 11 is located in the flow guide cover 12, a gas collecting cover 13 is disposed at the top of the liquid storage container 1, and an opening of the gas collecting cover 13 faces to an opening of the flow guide cover 12.
In detail, the air guide sleeve 12 and the air collection sleeve 13 may be made of plastic, stainless steel, aluminum alloy, and the like, and connected to the inner wall of the corresponding liquid storage container 1 through a connection structure, which may be injection molded, welded, or fixed by screws, so that the air guide sleeve 12 and the air collection sleeve 13 are tightly connected to the inner wall of the liquid storage container 1, thereby improving air tightness. Of course, a sealing structure, such as a sealing ring, can be added between the air guide sleeve 12 and the air collection sleeve 13 and the inner wall of the corresponding liquid storage container 1.
In operation, liquid and sterilizing gas enter the pod 12 through the inlet 11 and are exhausted through the opening at the top of the pod 12, after which the sterilizing gas rises to enter from the opening at the bottom of the gas-collecting hood 13. The air guide sleeve 12 has a guiding effect on the sterilizing gas flowing out from the liquid inlet 11, and the opening of the air guide sleeve 12 is opposite to the opening of the gas collecting sleeve 13, so that the sterilizing gas can flow in a concentrated manner to the opening direction of the gas collecting sleeve 13 under the guiding effect of the air guide sleeve 12 and enter the gas collecting sleeve 13, undissolved sterilizing gas can be effectively collected by the cooperation of the air guide sleeve 12 and the gas collecting sleeve 13, and the sterilizing gas can be conveniently and efficiently sucked by the second water ejector 31.
Referring to fig. 2, in one embodiment of the present invention, the flow area of the air guide sleeve 12 gradually decreases in the bottom-up direction, and the flow area of the air collection sleeve 13 gradually decreases. The flow area refers to the cross-sectional area of the air guide sleeve 12 and the air collecting sleeve 13 for liquid or gas to flow from bottom to top. The gradual decrease of the flow area of the air guide sleeve 12 indicates that the cross-sectional area of the air guide sleeve 12 gradually decreases from the bottom to the top of the air guide sleeve 12, for example, the air guide sleeve 12 may be a hollow truncated cone shape, the opening at the larger end of the bottom is connected to the bottom of the liquid storage container 1, and the opening at the smaller end faces the gas collecting sleeve 13. The gradual decrease of the flow area of the gas collecting hood 13 indicates that the cross-sectional area of the gas collecting hood 13 gradually decreases from the bottom to the top of the gas collecting hood 13, for example, the gas collecting hood 13 may be a hollow truncated cone shape, the opening at the smaller end is connected to the top of the liquid storage container 1, and the opening at the larger end faces the air guide hood 12. That is, the size of the bottom opening of the gas-collecting hood 13 is at least larger than the size of the top opening of the air-guiding hood 12,
the small size above the air guide sleeve 12 and the large size below the air guide sleeve are beneficial to intensively discharging the sterilizing gas through the opening, and the large size below the air collection sleeve 13 is beneficial to fully receiving the sterilizing gas flowing out of the opening of the air guide sleeve.
