Abstract
The utility model relates to a guide vane type submerged aerator which is fixed at the bottom of an aeration reaction tank by a bracket. The guide vane type submerged aerator consists of an aerator body, a shaft, a guide bearing, impellers, a mixing chamber, a guide vane and a spray nozzle, wherein the two impellers are connected to an aerator shaft; each impeller is of a three-blade structure; and the guide vane is arranged in the spray nozzle. The guide vane type submerged aerator is simple in structure, convenient to use, good in denitrification effect and low in production cost; and on one hand, the guide vane type submerged aerator can be used for releasing air, so that oxygen gas is obtained by the active sludge in the aeration reaction tank, and on the other hand, air scouring is carried out onto a membrane assembly.
Description
Technical field
The utility model relates to a kind of stator formula underwater jet aeration machine.
Background technology
Membrane separation technique combines with the active sludge technology and the membrane bioreactor (MBR that forms, membrane bioreactor), have characteristics such as effluent quality is good, floor space is little, in sewage recycling process, have very tempting potentiality, be considered to one of tool prospect technology of processing of 21 century recycling of water resource.But product in the market, the denitrogenation dephosphorizing effect is not ideal, and especially the technology of half-reaction district and anaerobic zone is not too perfect, also has aeration efficient to have much room for improvement.
Product in the market, the various negative impact waste of energy that the denitrogenation dephosphorizing effect is not ideal and numerous domestic sewage work also brings thus to the situation of this core link open loop of aeration, extensive control etc.
The utility model content
The utility model is for a kind of simple in structure, easy to use, denitrification effect is good, production cost is low stator formula underwater jet aeration machine that provides is provided.
The technical solution of the utility model is: described stator formula underwater jet aeration machine is fixed on bottom, aerated reaction pond by support, this stator formula underwater jet aeration machine is made of aerator main body, axle, guide bearing, impeller, mixing section, guide vane and nozzle, described two impellers are connected on the aeration arbor, described each impeller is three blade constructions, and described guide vane is arranged in the nozzle.
The utility model is simple in structure, easy to use, denitrification effect is good, production cost is low, and stator formula underwater jet aeration machine release air makes on the one hand that active sludge obtains oxygen in the aerated reaction pond, on the other hand membrane module is carried out air scour.
The underwater jet aeration machine 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 the impeller along with the impeller high speed rotating, under action of centrifugal force, throw away impeller, be formed centrally vacuum in the impeller to suck air thereby make, 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, the underwater jet aeration machine generally is installed at the bottom of the pond, it is far away that bubble arrives water surface distance, and oxygen dissolution is in the time of water in the atmosphere thereby increased, and bubble is through repeatedly cutting, after spraying disturbance, become countless tiny bubbles, its surface-area is very big, makes that oxygen is easier in the air is dissolved in the water.Short its sewage fully mixes with oxygen and contacts, and finishes biological process, and then reaches the purpose of purifying waste water.The underwater jet aeration machine is applied to improve the aeration operational efficiency greatly in the sewage recycling biochemical processing process.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 is inlet pipe among the figure, the 2nd, and stator formula underwater jet aeration machine, the 3rd, axle, the 4th, guide bearing, the 5th, impeller, the 6th, guide vane, the 7th, nozzle, the 8th, support.
Embodiment
A kind of stator formula underwater jet aeration machine, described stator formula underwater jet aeration machine 2 is fixed on bottom, aerated reaction pond by support 8, this stator formula underwater jet aeration machine 2 is made of aerator main body, axle 3, guide bearing 4, impeller 5, mixing section, guide vane 6 and nozzle 8, described two impellers 5 are connected on the aeration arbor 3, described each impeller 5 is three blade constructions, and described guide vane 6 is arranged in the nozzle 7.
