Abstract
An aerator comprises an air distributor and an air diffusing cover fixedly connected with the air distributor. The air diffusing cover is in the shape of an inverted umbrella, a guiding partition board is arranged at the end, which is connected with the air distributor, of the air diffusing cover, a sealing cover is disposed at the other end of the air diffusing cover, air distributing holes are arranged at a combination portion of the air distributor with the air diffusing cover, and air diffusing teeth are arranged on the outer surface of the air diffusing cover. The aerator is simple in structure, uniform in air distribution, high in oxygenation and excellent in aeration performance.
Description
Technical field
The utility model relates to waste disposal plant, is specially a kind of aerator that is used for sewage biochemical treatment engineering.
Background technology
Development along with environmental protection cause, the sewage biochemical treatment comes into one's own day by day, and treatment process also is on the increase, except that activated sludge process, biomembrance process, biological contact oxidation process also is widely used among the processing of municipal effluent and trade effluent in recent years, especially to some trade effluents, for fear of the expansion of active sludge, be convenient to treatment plant's station operational management, adopt biological contact oxidation process.But, no matter be activated sludge process, or contact oxidation method, aeration aerating all is indispensable important component part.
Aerator is exactly very important a kind of aerator, a kind of aerator that a plurality of sawtooth are set at the stream cover periphery that looses has appearred at present, sawtooth can be realized the cutting to air inlet, the defective of this structure is: only rely on periphery sawtooth few in number that air inlet is cut, air inlet can not be cut into more tiny bubble, cause the performance of aerator to reduce; Also have a kind of aerator that is provided with the diffusing stream cover of multilayer, the aeration performance of equipment promotes to some extent, but the structure more complicated, and it is also very inconvenient to keep in repair.
The utility model content
The technical problem that the utility model solved is: guarantee to realize the simplification of aerator structure under the prerequisite of aerator premium properties, a kind of aerator of simple in structure, excellent property is provided.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of aerator, comprise air distribution head, the diffusing stream cover affixed with air distribution head, the stream cover that should loose is inversed umbrella type, the coupling end of stream cover and air distribution head of loosing is provided with diaphragm, and the other end of stream cover that looses is provided with sealing cover, is with the remarkable difference of traditional aerator, described air distribution head is offered qi-emitting hole with the joint portion of the stream cover that looses, and described diffusing stream cover outer surface is provided with the gas dispersion tooth.
As further optimization, described qi-emitting hole is a grid type.
As further optimization, described gas dispersion tooth is the pyramid type projection.
As further optimization, described diaphragm is a shaped form.
Adopted the turbulent flow type aerator of above technical scheme to have following beneficial effect:
1, aeration performance is good: gas is imported air distribution head from inlet pipe, and at first the grid-like ventilating pit that can be provided with on the air distribution head carries out the cutting first time; The diaphragm of flowing through then be dispersed into gas-vapor mix liquid, and the shaped form diaphragm can be so that gas-vapor mix liquid dispersive be more even; Next utilize the pyramid type gas dispersion tooth of the stream cover outer surface setting of loosing that gas is further disperseed, thereby increased the gas-to-liquid contact area greatly, improved the utilization ratio of oxygen, gas distribution is even, the oxygen-transfer efficiency height;
2, simple in structure: the utility model mainly comprises air distribution head and two parts of stream cover that loose, in maintenance, also very convenient when changing.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a diaphragm structural representation in the utility model;
Embodiment
For technique means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, Fig. 2, a kind of aerator comprises the air distribution head 2 that is communicated with inlet pipe 1, and this air distribution head 2 is affixed with the stream cover 3 that looses.
Described air distribution head 2 is provided with the qi-emitting hole 21 of grid type, and described diffusing stream cover 3 is an inversed umbrella type, and the coupling end of loose stream cover 3 and air distribution head 2 is provided with shaped form diaphragm 31, and in addition, the outside surface of the stream cover 3 that looses is provided with conical gas dispersion tooth 32.
Principle of work of the present utility model is:
Gas at first can be carried out the cutting first time by the grid type qi-emitting hole 21 that is provided with on the air distribution head 2 from inlet pipe 1 input air distribution head 2; The shaped form diaphragm 31 of flowing through then is dispersed into gas-vapor mix liquid; Next the pyramid type gas dispersion tooth 32 of stream cover 3 outside surface settings of utilize loosing further disperses gas, thereby has increased the gas-to-liquid contact area greatly, has improved the utilization ratio of oxygen, and gas distribution is even, and the oxygen-transfer efficiency height.
The utility model is not limited to above-mentioned embodiment, and all are based on technical conceive of the present utility model, and the structural improvement of having done all falls among the protection domain of the present utility model.
