Abstract

The utility model discloses a shock wave mass transfer jet aerator, and relates to sewage or wastewater treatment equipment. The shock wave mass transfer jet aerator comprises a liquid suction inlet, a nozzle, an air suction pipe, a first suction chamber, a first mixing chamber, liquid suction holes, a second suction chamber, a second mixing chamber and a diffusion pipe, wherein the liquid suction inlet is formed in the center on the top of the first mixing chamber; the nozzle is arranged in the first suction chamber; two sides of the first suction chamber are respectively communicated with the air suction pipe; the first mixing chamber is connected with the second suction chamber; two sides of the second suction chamber are correspondingly provided with the liquid suction holes; and one end of the second mixing chamber is communicated with the second suction chamber, and the other end of the second mixing chamber is communicated with the diffusion pipe. The shock wave mass transfer jet aerator has the characteristics of high mass transfer efficiency of oxygen, uniform mixing, low possibility of blockage, low energy consumption, wear resistance and the like.

Description

The mass transfer by shock wave jet aerator
Technical field:
The utility model relates to the sewage or waste water treatment facility, is specifically related to a kind of mass transfer by shock wave jet aerator.
Background technology:
At the traditional aeration mode of sewage treatment area is blast aeration, and there are shortcomings such as dissolved oxygen efficiency is low, the mixing mixing effect is poor, device structure complicacy, electric energy consumption height in this aeration mode.Another kind of aeration mode is a jet aerator, and equipment is simpler comparatively speaking, and oxygen transfer efficient is than characteristics such as height, but mostly on the market jet aerator is single step arrangement at present, still exists dissolved oxygen insufficient, mixes problems such as inhomogeneous.
The utility model content:
The purpose of the utility model provides the mass transfer by shock wave jet aerator, it have oxygen transfer efficient high, mix more evenly, be difficult for stopping up, characteristics such as power consumption is low, wear-resistant.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises fluid intake 1, nozzle 2, air suction pipe 3, first suction chamber 4, first mixing section 5, liquid sucting port 6, second suction chamber 7, second mixing section 8, diffuser tube 9; Fluid intake 1 is arranged on the central position, top of first mixing section 5; Nozzle 2 is arranged on the inside of first suction chamber 4; The both sides of first suction chamber 4 are communicated with air suction pipe 3 respectively, and first mixing section 5 is connected with second suction chamber 7, and the both sides correspondence of second suction chamber 7 is provided with liquid sucting port 6; One end of second mixing section 8 is communicated with second suction chamber 7, and the other end is communicated with diffuser tube 9.
The utlity model has following beneficial effect: have oxygen transfer efficient high, mix more evenly, be difficult for stopping up, characteristics such as power consumption is low, wear-resistant.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1, this embodiment adopts following technical scheme: it comprises fluid intake 1, nozzle 2, air suction pipe 3, first suction chamber 4, first mixing section 5, liquid sucting port 6, second suction chamber 7, second mixing section 8, diffuser tube 9; Fluid intake 1 is arranged on the central position, top of first mixing section 5; Nozzle 2 is arranged on the inside of first suction chamber 4; The both sides of first suction chamber 4 are communicated with air suction pipe 3 respectively, and first mixing section 5 is connected with second suction chamber 7, and the both sides correspondence of second suction chamber 7 is provided with liquid sucting port 6; One end of second mixing section 8 is communicated with second suction chamber 7, and the other end is communicated with diffuser tube 9.
This embodiment in use; Except air suction pipe 3 tops; All be immersed in (the pending combined sewage that contains pollutent, biological bacteria) in the working liquid, make working liquid through power-equipments such as water pumps from fluid intake 1 entering and by the ejection of nozzle 2 high speeds, because the result of high-velocity jet with certain pressure; Preceding half section at first mixing section 5 forms the tight jet of high speed; Entrainment the air that flows in first suction chamber 4 by air suction pipe 3 simultaneously and converge,, the mikrobe flco is carried out the cutting first time the flow generation intense impact of low flow velocity in the downstream tube.The second half section of first mixing section 5, the mixed solution that ejects was lower slightly than first step nozzle flow velocity again as partial nozzle.Equally, the working liquid that liquid sucting port 6 inhalation devices are outer, the working liquid of second stage ejection mixes and turbulent flow with the liquid generation intensive that is got into by water sucking mouth 6, and impacts flow in the downstream tube, thereby makes biological floe carry out the cutting second time; In the first step and second stage mixing section, because this intensive mixes and action of turbulent flow, make and carry out liquid-solid two alternate mass transfer and reactions in the mixing section rapidly, this is a biological respinse fast that takes place under given conditions and two combined processes of mass transfer mutually.Because impact and turbulent acting in conjunction, the different in flow rate flow produces the intensive momentum-exchange in the mass transfer by shock wave jet aerator, forms intensive mixing shock wave each other.Shock wave results from the stage casing of first mixing section and the second half section of second mixing section.Shock wave transmits rapidly in mixing section, when wave amplitude during greater than the mixing section radial dimension, produces intensive turbulent fluctuation shear-stress between stream unit; This stress has produced strong cutting to biological floe; It is shredded, and particle diameter reduces greatly, and inner bacterium is exposed in the liquid former flco; Oxygen can be fused with it better, strengthened mass transfer process.
This embodiment have oxygen transfer efficient high, mix more evenly, be difficult for stopping up, characteristics such as power consumption is low, wear-resistant.
