Background

The harm of water pollution to human beings is self-evident, and a lot of water bodies are destroyed at present, and great investment is made in water body treatment in various places. At present, the important step of water body treatment is water body oxygenation, however, the existing water body oxygenation has high cost and low dissolved oxygen. And because the gas above the water body mostly contains miscellaneous gas, therefore need introduce fresh gas from the periphery, but based on prior art, the gas utilization ratio is low, and most gas is wasted.

Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

Fig. 1 and 2 show an embodiment of the water oxygenation device of the present invention, and the dotted line in fig. 1 shows the flow direction of the gas after being sprayed from the aeration pipe. The oxygen increasing device comprises a gas cylinder 1, a vent pipe 3 and an aeration pipe 4, wherein the aeration pipe 4 is positioned in water and is connected with the gas cylinder 1 through the vent pipe 3. A gas-collecting hood 5 is arranged above the aeration pipe 4, and the gas-collecting hood 5 is conical; an air bleed pipe 7 is arranged at the top of the gas collecting hood 5, the air bleed pipe 7 is connected with the vent pipe 3, a branch pipe electromagnetic valve 8 is arranged on the air bleed pipe 7, and a main pipe electromagnetic valve 9 is arranged on the vent pipe 3 between the air bleed pipe 7 and the gas bottle 1; the device is further provided with a main control box 10, which comprises a control unit therein for controlling the power consumption components, and which also provides electric energy for the power consumption components.

In the embodiment, a part of the gas sprayed from the aeration pipe 4 is dissolved in water, a part of the gas floats out of the water surface, and a part of the gas is gathered in the gas collecting hood 5 in the rising process of the water, so that the detention time of the gas in the water is increased, the lower part of the gas is contacted with the water, and the part of the gas can still be dissolved in the water, thereby improving the oxygen dissolving efficiency of the water body; after the gas in the gas collecting hood 5 is gathered to a certain degree, the gas enters the vent pipe 3 and is sprayed out of the aeration pipe again, so that the gas is recycled, the gas waste can be avoided, the oxygenation cost is reduced, and the device can be prevented from absorbing miscellaneous gas.

In order to reasonably control the gas in the gas collecting hood 5, an air pressure sensor 13 is arranged at the inner top of the gas collecting hood 5, the air pressure sensor 13 is used for detecting the gas pressure converged at the top of the gas collecting hood 5, and when the detected value reaches the upper limit of a preset value, the main control box 10 controls the main pipe electromagnetic valve 9 to be closed and simultaneously opens the branch pipe electromagnetic valve 8; when the detected numerical value reaches the lower limit of the preset value, the main control box 10 controls the main pipe electromagnetic valve 9 to be opened, and simultaneously closes the branch pipe electromagnetic valve 8. The pressure of the gas in the gas collecting hood 5 can be accurately measured by the gas pressure sensor 13, the work of the device is accurately controlled, and meanwhile, the branch pipe electromagnetic valve 8 is closed when part of the gas is still available, so that water can be prevented from entering the gas release pipe 7.

The optimal use condition of the device is that the water body is in a non-flowing or slow-flowing state, because the gas sprayed by the aeration pipe can be directly washed away by the fast water flow, so that the gas-collecting hood 5 cannot play a role in collecting the gas. For this purpose, a flow rate meter 12 is arranged near the aeration pipe 4, the flow rate meter 12 transmits the measured data to the main control box 10, when the flow rate is lower than the preset value, the main control box 10 controls the device to start oxygenation, and when the flow rate is higher than the preset value, the whole device stops oxygenation. The flow rate meter 12 can accurately know the flow rate of water and surely perform the pressurization operation.

The dissolution rate of gas in water is limited, and the energy consumption of the system can be increased only by injecting excessive gas once, in order to keep the device in the optimal working state, the pressure stabilizing valve 2 is arranged on the vent pipe 3, the gas entering the vent pipe 3 from the gas release pipe 7 and the gas cylinder 1 passes through the pressure stabilizing valve 2, so that the gas can be stably injected from the aeration pipe 4, the ratio of the gas dissolution amount to the injection amount can be maximized, and the condition of gas flow disorder can be avoided.

In addition, the gas that aerator pipe 1 spouts may appear the fusion phenomenon in aqueous, and this can reduce the area of contact of gas and water, for this reason, set up deflector 6 between aerator pipe 4 and gas collecting channel 5, this deflector 6 wholly appears lou hopper-shaped, and the gas that spouts from aerator pipe 4 is followed deflector 6 outer wall and is spread to the periphery, can break up gas on the one hand, and on the other hand, under the condition that aerator pipe 4 and gas collecting channel 5 interval are fixed, this kind of mode can increase the detention time of gas in aqueous, thereby improves dissolved oxygen efficiency.

The water oxygen deficiency makes the important reason that leads to the water to deteriorate, to the waters that the hydrosol oxygen seriously reduced, need lay oxygenation device more, for convenient laying in unified management, make gas collecting channel 5 and aeration pipe 4 suspend in aqueous through increasing flotation tank 11, consequently can lay the device in each region of water, and the device floats and sets up management and the maintenance that can make things convenient for the later stage.

It should be noted that when the device is put into water, part of the gas should be collected in the gas-collecting hood 5, which can prevent water from entering the gas-releasing pipe 7. In case of water entering the gas discharge pipe 7, the branch solenoid valve 8 is opened to allow a part of the gas to flow to the gas discharge pipe 7 at the time of starting aeration, thereby discharging the gas inside the pipe. Because the device can obviously reduce the waste amount of gas, the gas with high oxygen content can be selected.
