Abstract

The invention discloses a deepwater aerator. The deepwater aerator is composed of two major parts, namely a submersible pump and a jet pump; the jet pump is composed of a nozzle, a muffler, an air inlet pipe, an air mixing chamber, a diffusing pipe and the like; the submersible aerator is based on the principle of the jet pump; a liquid-air jet pump is adopted; two phases in the liquid-air jet pump flow from the outlet of the nozzle to the outlet of a throat pipe; at first, the air and liquid phases both are continuous phases; then the liquid is jetted out and broken, and the air is kept as the continuous phase, while the liquid is formed into a dispersed phase; next, liquid drops are mixed together continuously, and then the liquid is changed into the continuous phase again, while the air is changed into the dispersed phase; under the water pressure of 9m, the water and the air are mixed evenly, the jet flow is powerful, and generated bubbles are fine and even and long in time of staying underwater, therefore, the dissolution efficiency of oxygen is greatly improved; an aeration tank can be deepened appropriately so that the floor area needed by a sewage treatment plant can be saved, and the deepened aeration tank can certainly play a role in promoting the improvement of the sewage treatment process.

Description

A kind of deep water aeration machine
Technical field
The present invention relates to sewage treatment area, be specifically related to a kind of deep water aeration machine and principle of work thereof.
Background technology
Aerator is the key equipment of feedwater Biological Pretreatment, biological sewage treatment, and its function is that airborne oxygen is transferred in the liquid of aeration tank, to supply with the needed oxygen amount of aerobic microbiological, reaches the object of biological treatment.In sewage disposal, particularly, in denitrification dephosphorization technique, the aerator of high efficient and reliable plays an important role.Over nearly 5 years, external aerator has obtained develop rapidly, and for the aeration of different modes, researchist furthers investigate aeration effect.Aeration machinery is of a great variety; configurations; especially submersible aerator; with its working service simply, efficiently, feature cheaply, obtained the attention of many external famous environmental protection machinery production firms and research institution, this has been dropped into larger development research strength; research is divided into experimental study and Computational Fluid Dynamic Analysis both direction; its product just also enters in a large number in developing Chinese market, but for concrete submersible aerator method of design, the less discussion of foreign literature is arrived.At present, country is more and more higher to the requirement of sewage discharge.The development of domestic following aerator, will pay much attention to the research of submersible aerator at the aspect such as structure formation, technical indicator.Along with diving depth increases, pressure will increase thereupon, and bubble will be finer and closely woven, and the time of being detained under water will be longer, dissolved oxygen is also more abundant, and same sewage load, aeration tank is darker, and the shared land area in aeration tank is less, general pond can be increased to 5~7m deeply, maximum can reach 9m, and therefore, the aeration degree of depth becomes the focus of concern.
Summary of the invention
A kind of deep water aeration machine and principle of work thereof involved in the present invention, submersible aerator has adopted the principle of jet-pump, liquid-gas jet pump, two-phase flow wherein exports from jet exit to trunnion, originally gas-liquid two-phase is all external phase, then hydrofluidic fragmentation, gas remains external phase and liquid becomes disperse phase, and then drop constantly merges, liquid has become again external phase, and gas has become disperse phase.
In order to realize object of the present invention, technical scheme provided by the invention: a kind of deep water aeration machine, formed by submersible pump and jet-pump two parts, jet-pump parts are made up of parts such as nozzle, sourdine, inlet pipe, mixing chamber, diffuser tubes again.
Preferably, submersible aerator has adopted the principle of jet-pump, liquid-gas jet pump, two-phase flow wherein exports from jet exit to trunnion, originally gas-liquid two-phase is all external phase, then hydrofluidic fragmentation, gas remains external phase and liquid becomes disperse phase, and then drop constantly merges, liquid has become again external phase, and gas has become disperse phase.
Preferably, measure the air input under different water depth by under meter, measured electric current I and the operating pressure p of the submersible pump under respective water depth.
Beneficial effect of the present invention: under the hydraulic pressure of 9m, gas-vapor mix is even, and jet is strong, the bubble of generation is fine and closely woven, even, and the time of being detained is under water long, has greatly improved the dissolved efficiency of oxygen.Submersible aerator can adapt to deep water requirement, and high-speed camera and photographic camera are clear has shown that the gas-vapor mix under 9m hydraulic pressure is even, and jet is strong, and the bubble of generation is fine and closely woven, even, and the time of being detained is under water long, has greatly improved the dissolved efficiency of oxygen.Suitably deepen aeration tank, can save the required floor space of sewage work, to the process modification of sewage disposal, will play a good promoter action.
Brief description of the drawings
Fig. 1 is submersible aerator structural representation.
Wherein: 1-sourdine, 2-inlet pipe, 3-diffuser tube, 4-mixing section, 5-submersible pump, 6-shower nozzle.
Embodiment
Describe the preferred embodiment of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of deep water aeration machine and principle of work thereof, formed by submersible pump and jet-pump two parts, jet-pump parts are again by nozzle, sourdine, inlet pipe, mixing chamber, the part compositions such as diffuser tube, submersible aerator has adopted the principle of jet-pump, liquid-gas jet pump, two-phase flow wherein, from jet exit to trunnion, export, originally gas-liquid two-phase is all external phase, then hydrofluidic fragmentation, gas remains external phase and liquid becomes disperse phase, then drop constantly merges, liquid has become again external phase, gas has become disperse phase, measure the air input under different water depth by under meter, electric current I and the operating pressure p of the submersible pump under respective water depth are measured, the Experiment Data Records of each depth of water deep water aeration machine is as follows:
Wherein: Q is air flow quantity, H wfor depth of immersion.
Under the hydraulic pressure of 9m, gas-vapor mix is even, and jet is strong, and the bubble of generation is fine and closely woven, even, and the time of being detained is under water long, has greatly improved the dissolved efficiency of oxygen.Submersible aerator can adapt to deep water requirement, and high-speed camera and photographic camera are clear has shown that the gas-vapor mix under 10m hydraulic pressure is even, and jet is strong, and the bubble of generation is fine and closely woven, even, and the time of being detained is under water long, has greatly improved the dissolved efficiency of oxygen.Suitably deepen aeration tank, can save the required floor space of sewage work, to the process modification of sewage disposal, will play a good promoter action.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
