Description

Eddy flow oxygenator

Technical field

The utility model belongs to municipal wastewater pre-processing device technical field, and in particular to a kind of eddy flow oxygenator.

Background technique

With China's expanding economy, the demand of one side China water resource is being sharply increased, another aspect China water Pollution condition is still very serious, and municipal wastewater handles total amount and is continuously improved, with the general trend of new countryside construction, to life in the countryside The process demand of sewage is increasing, and cities and towns, the black smelly problem in rural area river are still generally existing, it would be highly desirable to solve.

These sewage treatment conventional process usually will first pre-process sewage, typical primary treatment processes and second level The pretreatment for the treatment of process generallys use raw water and removes the susceptible to plugging sundries such as pipeline water pump through grid, then pump promoted raw water into Enter setting pot, then through sedimentation basin/primary sedimentation pond, subsequent biochemical etc. is gone to handle.The effect of setting pot mainly removes in decontaminated water Inorganic particulate matter, protective conduit and pump mitigate the load of sedimentation basin from wearing and block, by inorganic particle and organic matter point It does not separate, improves the containing ratio and utility value of sludge organic components.

The type of setting pot is more, but exists mostly and such as take up a large area, and structures are complicated, and cost is high, and treatment effeciency is low, Sediment outflow is more difficult or mechanical equipment is complicated, and maintenance capacity increase leads to fluctuation of service.Currently, sewage treatment is used more Setting pot has rotational flow grit chamber and aerated grit chamber.Rotational flow grit chamber is to be vortexed to separate sand grains with organic matter using waterpower, is arranged Sand mode is bottom sand pump sediment outflow or airlift sediment outflow；Aerated grit chamber is to transport pool inner water stream helically It is dynamic, it generates centrifugal force and throws out the inorganic particulate matters such as sand grains and separation of sinking, sediment outflow mode sand pump or mechanical sediment outflow. Rotational flow grit chamber and the comparison of aerated grit chamber disadvantage are as follows.

Rotational flow grit chamber needs to grasp water flow when in use, should be in good condition, otherwise treatment effeciency declines；Aerated grit chamber To master aeration intensity when in use, otherwise treatment effeciency declines, and energy consumption is high, and operating cost is high.

Utility model content

The purpose of this utility model is to provide a kind of eddy flow oxygenators, to solve mentioned above in the background art ask Topic.

To achieve the above object, the utility model provides the following technical solutions: a kind of eddy flow oxygenator, including cylinder and into Gas blowout emitter, the lower part of the cylinder connect the taper bucket, and the cylinder top connects end socket, the jet port of the air inlet injector The eddy flow water inlet pipe tangentially connected with eddy flow oxygenator cylinder is connected, and the air inlet injector is equipped with original water inlet and air Import, the top position of the barrel upper seal head are equipped with water outlet, and the taper bucket bottom is equipped with sand export.

Preferably, the cylinder internal pressure control is in 0.15-0.25MPa, and air inlet injector outlet pressure is not less than 0.3Mpa。

The technical effect and advantage of the utility model: air inlet injector and eddy flow is ideally utilized in the eddy flow oxygenator The combination of oxygenator apparatus body, pre-processes sewage, while removing raw water sand grains, has carried out pre-exposure to raw water Gas disposal, the organic matter in sewage of degrading, is conducive to subsequent biochemical treatment, the eddy flow oxygenator is for substituting the prior art Setting pot, the setting pot in the form of any one before compare, and treatment effeciency and treatment effect are well very much, and should Device is steel systeming equipment, simple and compact for structure, applied widely, is not required to separately set sediment outflow equipment, greatly reduce equipment investment with Occupation area of equipment, equipment operation is easy to operate, easy to maintain, other than raw water intake pump, is not required to other power sources, saves Energy consumption, operating cost are low.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the structure top view of A-A at the utility model Fig. 1.

In figure: 1 cylinder, 2 the taper buckets, 3 end sockets, 4 air inlet injectors, 5 former water inlets, 6 air intlets, 7 eddy flow water inlet pipes, 8 water outlets, 9 sand exports.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

The utility model provides a kind of eddy flow oxygenator as shown in Figs. 1-2, including cylinder 1 and air inlet injector 4, institute The lower part connection the taper bucket 2 of cylinder 1 is stated, 1 top of cylinder connects end socket 3, the jet port and eddy flow of the air inlet injector 4 The tangentially connected eddy flow water inlet pipe 7 of oxygenator cylinder 1 is connected, the air inlet injector 4 be equipped with original water inlet 5 and air into Mouth 6, the top position of 1 upper cover 3 of cylinder are equipped with water outlet 8, and 2 bottom of the taper bucket is equipped with sand export 9.

Specifically, pressure is controlled in 0.15-0.25MPa in the cylinder 1, and 4 outlet pressure of air inlet injector is not less than 0.3Mpa, to ensure the efficient process of eddy flow oxygenation.
