Description
Technical Field
The utility model relates to an aeration equipment field, concretely relates to high-efficient integration air of large capacity oxygenates platform.
Background
China is a country with serious environmental pollution. Large area of polluted water, high content of rich nutrient substances and diversified pollution forms. There are a large number of rivers, lakes, ponds, black and odorous ditches, fish ponds, wastewater ponds of large-scale farms, etc. that have appeared in recent years, and most of these waters are in a eutrophic state. In order to solve the problem of eutrophication of rivers and lakes and improve water quality, one of the important measures is to oxygenate water.
The existing oxygenation equipment and technology in China comprise an impeller type aerator, a blower, a micropore air distribution pipe aeration system, a pure oxygen-micropore air distribution pipe aeration system, an impeller air suction plug flow type aerator, an underwater jet aerator and the like. The oxygenation technologies and equipment are difficult to realize the problems of high-power, high-efficiency and low-cost oxygenation of natural water bodies such as rivers, lakes, pool weirs, ditches and the like.
The impeller type aerator is a mechanical aeration mode, and water splash is splashed by stirring to increase the contact area for aeration. However, the oxygen increasing machine does not directly charge air into water, but converts most of electric energy into mechanical energy for indirect oxygen charging, so that the oxygen charging efficiency is not high.
The air blower-micropore air distribution pipe aeration system is a blast aeration system consisting of an air blower and an air distribution pipe. This is a highly efficient oxygenation system widely used in sewage treatment plants. However, the installation of the aeration pipe in the system needs to be operated in different processes, and simultaneously, an aeration tank needs to be additionally built, and a pipeline system is independently installed, so that the system cannot be installed in the tank as a whole at one time, especially in a naturally formed water area, and the aeration system is difficult to install in a natural water area because the ground is uneven, the terrain is complex, the cost of the system is high, the application range is limited, and the aeration system is difficult to install in the natural water area.
The impeller air suction plug-flow aerator sucks air for oxygenation through the mechanical rotation of an impeller. The negative pressure inhaled air is also mechanical oxygenated in nature, the inhaled air quantity and the aeration quantity are limited, the device can only inhale oxygen on the surface of the water body, and the aeration depth is shallow, so the oxygen dissolution rate is low.
The underwater jet aerator uses a submersible pump to suck water, pressurize the water, push the water out of a pump body at a high speed, uses a water ejector arranged on a water outlet guide pipe to suck air, and makes a gas-water mixed solution enter a water body after hydraulic mixing and cutting. But the pump is easily blocked. Once the water pump is blocked or has other faults, the equipment needs to be lifted out of the water surface for maintenance, and the maintenance is troublesome. Similarly, because the jet flow inspiration capacity is very limited, the oxygenation of large-capacity water bodies cannot be realized.
In summary, in the existing underwater air oxygenation pipeline system for sewage treatment, each part of the system is separated, and an aeration tank needs to be specially constructed, and a pipeline system is specially constructed and installed in the tank, so that an aeration system cannot be directly installed underwater as a whole in one step, the cost is high, the installation and maintenance difficulty is high, and the use condition is limited by the water area environment. In addition, the existing oxygenator realizes the purpose of oxygenating by mechanically stirring, splashing water and increasing the contact surface of a water body and air, which is indirect oxygenating and surface oxygenating, cannot realize deep oxygenating and has low oxygenating efficiency. Deep oxygenation cannot be performed.

wherein F is the resistance (Newton) of the fluid section, A is the maximum cross-sectional area of the damping valve (square meter), and rho is the density of the water body (kg/m)3) ζ is a damping coefficient, and v is an air flow rate (m/s).
The thrust in the air flow direction is proportional to the flow velocity squared, so the damper valve is sensitive to the flow velocity. When the river channel is uneven, the aeration depth of some aeration heads is reduced due to water flow impact, the flow rate of the aeration heads is increased, the air self-balancing damping valve 10 is upwards supported, the area of an air passage is greatly reduced, and the flow rate is reduced. Conversely, if the flow rate of a certain aeration head 9 is reduced, the resistance of the air self-balancing damping valve 10 is also reduced, so that the flow rate is increased. By this design, the air flow rate of each aeration head 9 of the whole air oxygenation platform can be basically consistent.
