Abstract
The invention relates to a guide vane type submersible aerator. The guide vane type submersible aerator is fixed at the bottom of an aeration reaction pool through a bracket, and is composed of an aerator main body, a shaft, a guide bearing, impellers, a mixing chamber, guide vanes, and a nozzle. The two impellers are connected to the aerator shaft, each of the impellers has a three-vane structure, and the guide vanes are arranged in the nozzle. The guide vane type submersible aerator provided by the invention has the advantages of simple structure, convenient use, good denitrification effect, and low production cost. By releasing air, on the one hand the guide vane type submersible aerator can make activated sludge in the reaction pool get oxygen, and on the other hand the guide vane type submersible aerator can perform gas scouring on membrane components.
Description
Technical field
The present invention relates to a kind of guide-vane submersible aerator.
Background technology
Membrane separation technique combines with active sludge technology and the membrane bioreactor (MBR that forms, membrane bioreactor), there is the features such as effluent quality is good, floor space is little, in sewage recycling process, have and extremely lure human potential, be considered to one of tool prospect technique of processing of 21 century recycling of water resource.But product in the market, Nitrogen/Phosphorus Removal is not ideal, and especially the technique of half-reaction district and anaerobic zone is not too perfect, also has aeration efficiency to have much room for improvement.
Product in the market, Nitrogen/Phosphorus Removal is not ideal, and numerous domestic sewage work is to the situation of this core link open loop of aeration, extensive control the various negative impact waste of energy that bring thus etc.
Summary of the invention
The present invention provides a kind of simple in structure, easy to use, denitrification effect is good, production cost is low guide-vane submersible aerator in order to overcome the above problems.
Technical scheme of the present invention is: described guide-vane submersible aerator is fixed on bottom, aerated reaction pond by support, this guide-vane submersible aerator is made up of aerator main body, axle, guide bearing, impeller, mixing section, guide vane and nozzle, two described impellers are connected on aeration arbor, described each impeller is three blade constructions, and described guide vane is arranged in nozzle.
The present invention is simple in structure, easy to use, denitrification effect is good, production cost is low, and guide-vane submersible aerator release air makes active sludge in aerated reaction pond obtain oxygen on the one hand, on the other hand membrane module is carried out to air scour.
Submersible aerator effectively utilizes fluid jet and impeller pump principle of work, adopt the direct drives impeller high speed rotating of submersible machine, be full of water in impeller along with impeller high speed rotating, under the effect of centrifugal force, throw away impeller, thereby make to be formed centrally vacuum with air amount in impeller, air mixes through impeller, mixing section with water, ejection at a high speed under centrifugal action.Water flow jet is extremely strong, causes effective convection cell disturbance, makes air filled cavity further be divided into numerous tiny bubbles.Because bubble diameter is little, lift velocity is slow, at the bottom of submersible aerator is generally installed on pond, it is far away that bubble arrives water surface distance, thereby increased atmospheric oxygen and be dissolved in the time of water, and bubble is through repeatedly cutting, spray after disturbance, become countless tiny bubbles, its surface-area is very large, makes in air oxygen more soluble in water.Short its sewage fully mixes and contacts with oxygen, completes biological process, and then reaches the object of purifying waste water.Submersible aerator, is applied in sewage recycling biochemical processing process, greatly improves aeration operational efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure, 1 is inlet pipe, the 2nd, and guide-vane submersible aerator, the 3rd, axle, the 4th, guide bearing, the 5th, impeller, the 6th, guide vane, the 7th, nozzle, the 8th, support.
