Technical field
The invention belongs to the method that the dissolution of contaminated water oxygen in the sewage treatment area improves, relate in particular to the method and apparatus of a kind of wind-force from pneumatic aeration.
Background technology
The highest processing means of frequency of utilization when existing aerobic sewage treatment process is sewage disposal for keeping dissolved oxygen concentration in the reactor, must adopt certain method oxygen supply in reactor, promptly common alleged aeration.Aeration mode at present commonly used has two kinds of blast aeration and mechanical aerations.These two kinds of methods are power with the electric energy all, drive some mechanical rotation, and the mode of air or oxygen with bubble is delivered in the water, and the oxygen in the micro-bubble is by in the dissolving entry of aqueous vapor interface, thus raising water body dissolved oxygen concentration.Also some aerating apparatus is thrown into the form of water with the globule in the air, improves oxygen in water concentration by the globule with contacting of air.
Above-mentioned aeration mode is a power with the electric energy all, need expend a large amount of electric energy during aeration, is the key link that sewage disposal device produces working cost.Obviously, developing a kind of is the aeration mode of power with the renewable energy source, will reduce the energy consumption of sewage treatment process greatly, meets country's " energy-saving and emission-reduction " requirement.
Summary of the invention
The purpose of this invention is to provide a kind of is the automatic aeration method and the device of power with the wind energy---water body wind-force is from the method and apparatus of pneumatic aeration, to solve the existing high defective of aeration mode energy consumption.
The present invention is an existing patent of utilizing the vertical shaft type blower fan structure of being made up of fan blade, transmission rod, i.e. " the unidirectional board-like wind power apparatus that keeps out the wind " (2005200799720), it be a kind of be the unidirectional board-like wind power apparatus that keeps out the wind of vertical axes of mechanical energy with wind energy transformation, the wind comes from of any direction all there is corresponding windsheild, and can both export torque to various wind directions, and do not need to be provided with specially device and speed limiting device to wind direction.And it is simple and reasonable, and swinging moment is big, and serviceability is strong, the wind energy utilization height, and manufacturing and installation and maintenance expense are low, applied widely.Construct power set of the present invention on this basis.
The invention is characterized in: it comprises fan blade, transmission rod, air compression plant, pipeline and aeration head, the transmission rod upper end is connected with the fan blade rotating shaft, the transmission rod lower end is connected with air compression plant, the other end of the pipeline that the air compression plant air outlet connects is installed micro porous aeration head, and micro porous aeration head evenly is arranged in the water body of sewage lagoon bottom.
Above-mentioned aeration head is a micro porous aeration head.
Method of the present invention: earlier micro porous aeration head evenly is arranged at the sewage lagoon bottom in water body, with pipeline aeration head is connected with the air compression plant air outlet then, the transmission rod that is connected with air compression plant is under the drive of fan blade, the compression of air in the air compression plant is entered aeration head, form micro-bubble and enter water body, airborne oxygen is fully contacted with water and dissolve and realize aeration in the water inlet.
The present invention does not need to be provided with specially device and the speed limiting device to wind direction, and it is simple and reasonable, and it is low to consume energy, make and the installation and maintenance expense low, the wind energy utilization height is effectively realized the dissolved oxygen in aeration, the raising water body and is reached the treatment effect of water body.
Further specify the present invention below in conjunction with accompanying drawing and by specific embodiment.
Description of drawings
Fig. 1, basic structure synoptic diagram of the present invention.
Wherein, 1 fan blade, 2 transmission rods, 3 air compression plants, 4, pipeline, 5 aeration heads, 6 sewage lagoons.
Embodiment
As Fig. 1, the invention is characterized in: it comprises fan blade 1, transmission rod 2, air compression plant 3, pipeline 4 and aeration head 5, transmission rod 2 upper ends are connected with fan blade 1 rotating shaft, transmission rod 2 lower ends are connected with air compression plant 3, the other end of the pipeline 4 that air compression plant 3 air outlets connect is installed aeration head 5, and aeration head 5 evenly is positioned in the water body of sewage lagoon 6 bottoms.
Above-mentioned aeration head 5 of the present invention is micro porous aeration heads.
Above-mentioned air compression plant 3 adopts commercial device, and the simplest is the pedal inflator.When transmission rod 2 moved downward under the driving of fan blade 1, extruding air compression plant 3 was emerged the air in the air compression plant 3 by aeration head.
Above-mentioned aeration head 5 is the husky aeration head of micropore.Its function is a micro-bubble for being compressed air dispersion, increases the contact area of air and water, improves the water body dissolved oxygen concentration.
Move fan blade 1 when wind and rotate, drive transmission rod 2 and move up and down, pressurized air compression set 3 when transmission rod 2 moves downward makes the air pressures increase in the air compression plant 3 and enters in the intravital aeration head 5 of water the formation tiny bubble.Oxygen dissolution in the bubble, thereby the dissolved oxygen of raising water body.
Embodiment 1
Make above-mentioned wind powered aerating apparatus one cover, it is characterized by: fan blade length 50cm, every fan blade area is 750cm, totally 3 fan blades.The air compression plant volume is 20L.Utilize it in the active sludge waste disposal plant of volume, to carry out aeration for 1m3.When wind speed was 3.2m/s (light breeze), this device aeration rate was 60L/min.When wind speed was 9.0m/s (fresh breeze), this device aeration rate was 140L/min.
