Description

TECHNICAL FIELD

[0001] The present application relates to a water-sealed kinetic bubble generator for aquaculture water treatment and sewage treatment. BACKGROUND

[0002] At present, small bubbles are often used in aquaculture and sewage treatment projects for oxygenation, degassing and water treatment, such as using small bubble bottom to oxygenate and change the bottom, using a large number of small bubbles for aeration to degas, using a large number of small bubbles for aeration to oxygenate in the nitrification tank while making the filter material roll and self-clean, etc. Due to the insufficient kinetic energy of the small bubbles, the effect in each application scenario is not good. For example, when the small bubble bottom is used to oxygenate and change the bottom, due to the insufficient kinetic energy, the water flows slowly up and down, the influence range is small, the up and down convection is not complete, and organic matter accumulates at the bottom, so the effect of changing the bottom is poor; when the water is degassed, due to the insufficient kinetic energy, the water is not stirred quickly and fully enough, and negative pressure cannot be generated, so the water cannot be degassed by using negative pressure; and in the nitrification tank, when the MBBR fluidized bed is used for nitrification reaction, due to the insufficient kinetic energy, the filter material cannot be filled in a large amount, and once the filling rate of the filter material exceeds 60%, the small bubbles are difficult to fully stir the filter material, which limits the filling rate of the filter material. And if larger bubbles are used, the required air volume will increase exponentially, and the energy consumption will be too large. The existing air explosion type large bubble oxygenation device on the market is very prone to failure in the sewage environment due to the use of movable valve accessories, is easily affected by foreign matter, and cannot produce large bubbles due to the loose closing of the valve, or the valve itself is damaged due to frequent starting and stopping. SUMMARY

[0003] In order to overcome the shortcomings of the prior art, such as insufficient kinetic energy, high power consumption, low efficiency and high failure rate, the present application provides a low-energy kinetic bubble generating device with a new structure and no movable parts. A water seal is generated by using a simple water pipe structure to form a gas storage chamber. When the air pump continuously compresses air into the gas storage chamber and breaks the water seal, the air in the gas storage chamber is released instantly, generating a large amount of kinetic energy to push the water, thereby generating intermittent kinetic bubbles. The present application uses water as a valve, and the entire device has no movable parts and is almost not damaged; there is no requirement for the air volume of the air pump, and the larger the air volume, the faster the frequency, and the smaller the air volume, the slower the frequency.

[0004] The present application is a water-sealed kinetic bubble generator, which comprises a gas storage chamber, a water seal device, an air outlet, an air inlet, a base, a water inlet, and a counterweight chamber. The gas storage chamber is a container with a water inlet at the lower end and an air inlet and an air outlet at the upper end. The air outlet itself can generate a water seal to become a water seal pipe by using a water pipe structure, or an independent water seal device can be installed. It is worth mentioning that the water seal device does not necessarily have the shape of a water pipe, but can also be a container with an open end in any shape. Any structure that can generate a water seal cannot be excluded from the scope of the water seal device. The counterweight bin outside the gas storage bin is used to fill the counterweight material to make the device sink in water. The base is located at the bottom of the gas storage bin and is used to prevent the device from sinking into sludge and support the counterweight bin. The water inlet is provided on the base. The filter screen can be selectively installed according to the working condition. The water inlet can also be selectively arranged according to the working condition, for example, the bottom water inlet is selected when the sludge on the bottom needs to be stirred, and the top water inlet is selected when the sludge is not desired to be stirred.

[0005] When in use, the counterweight bin is filled with counterweight material, and the device sinks to the bottom of the water. At this time, water flows into the gas storage bin through the water inlet. The air pump pressurizes the high-pressure gas into the gas storage bin through the gas inlet. At this time, the water level in the gas storage bin slowly decreases, but the gas cannot be discharged due to the existence of the water seal. When the water level continues to decrease, the water in the water seal is discharged, the gas outlet is opened, and the gas is instantaneously discharged from the gas outlet. A large amount of kinetic energy is generated by the huge gas bubbles, which pushes the bottom water upwards. After the gas is discharged, water enters from the water inlet and again floods the gas storage bin to submerge the water seal, and the cycle is repeated to continuously and intermittently release the kinetic energy bubbles.
