Abstract

The utility model relates to an efficient oxygen-increasing aerating apparatus which belongs to the technical field of sewage treatment and mainly comprises a shell and an inner core located in a middle area, wherein an air inlet is arranged at one end of the upper part of the shell; a pressurizing bin, a nozzle, a mixing bin and a diffusion flow guide pipe are sequentially communicated and formed in the inner core; the pressurizing bin is approximately of a V-shaped structure with caliber gradually increasing from bottom to top; the lower end of the pressurizing bin is communicated with the mixing bin through the nozzle; the air inlet is communicated with the mixing bin through a pipeline; and the diffusion flow guide pipe is arranged at the lower part of the apparatus and is communicated with the mixing bin. The efficient oxygen-increasing aerating apparatus has high sewage treatment and aeration process efficiency, stable running and better effect.

Description

Efficient oxygenation aerating apparatus

Technical field

The utility model relates to a kind of efficient oxygenation aerating apparatus, belongs to technical field of sewage.

Background technology

In the sewage treatment technology field, the aerobe method of purification has vital status, and in the aerobe decontamination process, aeration system is again a core technology.In the existing sewage treatment industry, adopt traditional air blast aeration mostly in the aerobe purification process mode of active sludge oxygen supply, this technology oxygen transfer rate is about 20%, the pond degree of depth has limitation, should be controlled in 5 meters, blower power is selected bigger, and 1 cubic metre of sewage of every processing needs air demand more than 4 cubic metres, existing aerating apparatus complicated layout, cost height, noise are big, remain improvement in fact.

Summary of the invention

Therefore, the purpose of this utility model is to provide a kind of novel efficient oxygenation aerating apparatus, and it is simple in structure, cost is low, noise is low, effective.

For achieving the above object, the utility model provides following technical scheme:

Efficient oxygenation aerating apparatus comprises housing and is positioned at the inner core of central region that inlet mouth is positioned at an end on housing top.Supercharging storehouse, nozzle, mixing bunker and diffusion thrust-augmenting nozzle breakthrough form successively are formed among the inner core.Wherein, the supercharging storehouse roughly forms the v type structure that bore from top to bottom progressively enlarges, and communicates with mixing bunker by nozzle in its lower end.Inlet mouth also is communicated with mixing bunker by pipeline.The bottom that the diffusion thrust-augmenting nozzle is positioned at device communicates with mixing bunker.

According to the further setting to technique scheme, mixing bunker forms rectangular configuration.

The development of the efficient oxygenation aerating apparatus of the utility model and the practical application in sewage treatment project have substituted traditional ancient customs aeration system equipment, make that the aeration in sewage treatment process efficiency is higher, move more stable, better effects if.

Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.

Fig. 1 is the utility model structural representation.

1 inner core; 2 housings; 3 inlet mouths; 4 supercharging storehouses; 5 nozzles;

6 mixing bunkers; 7 diffusion thrust-augmenting nozzles.

Embodiment

As shown in Figure 1: efficient oxygenation aerating apparatus comprises housing 2 and is positioned at the inner core 1 of central region that inlet mouth 3 is positioned at an end on housing top; Supercharging storehouse 4, nozzle 5, mixing bunker 6 and diffusion thrust-augmenting nozzle 7 breakthrough form successively are formed among the inner core; Wherein, supercharging storehouse 4 roughly forms the v type structure that bore from top to bottom progressively enlarges, and communicates with mixing bunker 6 by nozzle 5 in its lower end; Inlet mouth 3 also is communicated with mixing bunker 6 by pipeline; The bottom that diffusion thrust-augmenting nozzle 7 is positioned at device communicates with mixing bunker 6.

Efficient oxygenation aerating apparatus power source is from the recycle pump that is complementary with it, power is controlled at about 15Kw, sewage and air vibrated in the device hybrid chamber smash, and the mixing of pressure is arranged after the diffusion thrust-augmenting nozzle is delivered to basin bottom, discharge by processing requirement, this kind processing method oxygen transfer rate can reach 45%, and available depth can reach more than the 10M, and every processing 1M3 sewage air demand is about 2M3.With fluidics rationally, innovate, be successfully applied in the sewage treatment process, it is combined by a kind of high-efficiency jet flow aeration device and the recycle pump that is complementary.Sewage is by being pumped into device supercharging storehouse 4, penetrate at a high speed through nozzle 5, this moment is under the effect of high velocity liquid stream, jet hole forms negative pressuren zone, and air is just sucked from suction port 3, then in 6 vibrations of device mixing bunker, broken pressurization is fused, produce continuous liquid-gas two-phase flow, after diffusion thrust-augmenting nozzle 7 send, according to processing requirement discharge.When quality is upwards overflowed at the bottom of the pond than the light air of sewage, mix contact again with sewage, realize transmitting to sewage oxygen the second time.

This device uses in the sewage with animal's excrement treatment project, fields such as city domestic sewage treatment project and dyeing and printing sewage treatment project.

More than the utility model has been done detailed description; can not think that protection domain of the present utility model only is confined to above-mentioned embodiment; if do not have to produce in essence difference, the deduction or replace of above-mentioned embodiment still are regarded as within protection domain of the present utility model with the technical scheme of the utility model claim.

Claims

1. efficient oxygenation aerating apparatus, comprise housing and be positioned at the inner core of central region, inlet mouth is positioned at an end on housing top, it is characterized in that also comprising supercharging storehouse, nozzle, mixing bunker and diffusion thrust-augmenting nozzle, aforementioned supercharging storehouse, nozzle, mixing bunker and diffusion thrust-augmenting nozzle breakthrough form successively are formed among the inner core; Wherein, the supercharging storehouse roughly forms the v type structure that bore from top to bottom progressively enlarges, and communicates with mixing bunker by nozzle in its lower end; Described inlet mouth also is communicated with mixing bunker by pipeline; The bottom that described diffusion thrust-augmenting nozzle is positioned at device communicates with mixing bunker.

2. according to claim 1, it is characterized in that described mixing bunker forms rectangular configuration.
