Description
Technical Field
The invention relates to the field of aeration, in particular to an intelligent mobile underwater aeration system and method.
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, pond weirs, rivers 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 blower-microporous gas distribution pipe aeration system is an oxygenation technology widely used in sewage treatment at home and abroad due to high oxygenation efficiency and large oxygen charging amount. It consists of a blower, an air distribution pipeline and an aeration head. However, the installation of the aeration pipe in the system requires the operation of the separate process, and meanwhile, an aeration tank needs to be additionally built, and a pipeline system needs to be separately installed, so that the aeration tank needs to be separately built. Especially in the naturally formed water area, the uneven ground, the complex terrain, the great water level change, the high cost of the system and the limited application range make it difficult to install the aeration system 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.
The high-speed aerodynamic aeration ship disclosed in application number CN201721126005.4 adopts a fan to provide an air source, and uses two air injection pipes to perform underwater air injection aeration. The design has no aeration head, the air quantity is highly concentrated, the air concentration around the air pipe is very high, the contact surface of air and water is very small, and the aeration effect is very poor. In addition, the patent has baffles on the duct that are inflexible to turn and cannot be reversed. The system has no direction control device, and the aeration ship can not turn. The air oxygenating vessel disclosed in application No. 201521103484.9, although capable of underwater aeration, relies on manual driving, propelled by mechanical impellers, and is costly to operate and manage and energy consuming.
In conclusion, the conventional aeration device can not realize deep oxygenation and has low oxygenation efficiency. The movable oxygenation technology has small aeration area and small aeration quantity. Especially, the functions are single, manual driving and operation are needed, and more efficient full-water-area oxygenation and real-time monitoring of water bodies, fish schools and the like cannot be achieved.

The blower is usually a vortex blower, or roots blower. The pressure head of the fan is determined according to the aeration depth. When the aeration depth is within the range of 0.5-3.5m, a vortex fan is adopted, and when the aeration depth is within the range of 3.5-8m, a Roots fan is adopted.
The aeration pipeline system mainly comprises an aeration main pipe 16 and aeration branch pipes 15, wherein the aeration main pipe 16 is connected with an air outlet of the fan and supplies air; the branch aeration pipes 15 mainly divide the supply air, and send the divided air or oxygen to the aeration head 13, and perform dispersed aeration through the aeration head 13. The aeration pipeline system is horizontally arranged on the aeration support platform through welding or bolts, so that the pipeline system is ensured not to displace.
The blower fan directly enters the air distribution box 18 through the air duct 11, the aeration main pipe 16 is connected to the air distribution box 18, and distributes air to the aeration main pipe 16 and then to the aeration branch pipes 15 through the aeration main pipe 16. A fan outer cover 3 is arranged outside the fan. The air distribution header mainly enables pressurized air generated by the fan to be uniformly distributed on the aeration main pipe, and then the air is filled into water through the aeration branch pipe and the aeration head.
The platform support 17 mainly plays a supporting role and is used for supporting the aeration pipeline system and the aeration head 13. The platform support 17 mainly comprises a horizontal support and an inclined strut support below the aeration pipeline system, the horizontal support comprises a transverse horizontal support and a longitudinal horizontal support, and the transverse horizontal support and the longitudinal horizontal support are mutually staggered to form an interpenetrating network structure. The bracing support is fixedly connected below the end part of the horizontal support. An inverted ladder shape is formed between the horizontal support and the inclined support, the stability of the whole integrated structure platform in water can be improved due to the inverted ladder shape, the installation space of the upper aeration head can be enlarged, and the aeration water area is enlarged. The platform support 17 is a whole body, which is convenient for installation, movement and placement, and in the using process, the whole device suspends the aeration platform in water bodies needing aeration and oxygenation, such as rivers, lakes and the like through the air buoyancy tanks 10, the buoyancy tank connecting plates 9 and the aeration device lifting conduits 6.

And a part of the box body floats on the water surface through calculation of gravity load and buoyancy. The gravity load of the air flotation tank 10 includes the weight of the entire aeration platform and the weight of 2-3 operators.
