Abstract

The utility model provides a dual -purpose aerator, belongs to environmental protection technology field, characterized by: airtight cover has air conduit outside the fluid pipeline, and the gas -liquid mixture nozzle is installed in extending to the mixing chamber to the fluid pipeline nozzle outside the mixing chamber. The beneficial effects are that: JAS dual -purpose aerator is than traditional method aeration energy -saving 20 percent - 50 percent. It is that micropore aeration of tradition is first 30 times big singly to chew the oxygen service area. The betting contest can not take place for 12h yet in the downlap of blowing -out machine state, and traditional aeration shut down 1h has the jam probably. Can realize the water conservancy stirring under the blowing -out machine condition, prevent that the anaerobism from producing marsh gas, the danger of blasting, catch fire.

Description

Dual-purpose aerator
Technical field
The invention belongs to environmental technology field, relate to a kind of improvement for the treatment of all kinds of stain disease equipment.
Background technology
Along with the enforcement of " the 2000 in China water and wastewater industry strategy of sustainable development ", it is imperative in Water utility that sewage popularizes secondary advanced treatment, activated sludge process wastewater processing technology obtains application and development more and more widely, be used successfully to sanitary sewage, food wastewater, each field such as each trade effluent, but traditional aeration oxygen system cannot realize intermittent type, single groove anaerobism, the aerobic requirement waiting novel active sludge technique, namely in a biological treating tank, realize intermittent aeration and be beneficial to dephosphorization, denitrogenate, the organism of degraded difficult for biological degradation, prevent sludge bulking etc.
Summary of the invention
The object of the invention is: provide a kind of dual-purpose aerator, it integrates aeration and stirs, and anaerobism and stain disease treatment facility that is aerobic and the whole body, can realize anaerobism and stir and aerobic aeration dual-use function.
Technical scheme of the present invention is: have air line at the outer airtight cover of fluid pipeline, fluid pipeline nozzle extends in mixing section, is provided with gas-liquid mixed nozzle outside mixing section.
The invention has the beneficial effects as follows:
The dual-purpose aerator of 1.JAS can save energy 20%-50% than Traditional Method aeration.
2. singly chewing oxygen service area is large 30 times of tradition micro porous aeration head.
3. also betting contest can not occur stopping super 12h under fan condition, and traditional aeration is shut down 1h and is just had blocking may.
Can hydraulic mixing be realized in blowing-out machine situation, prevent anaerobism from producing biogas, to blast, fire hazard.
Accompanying drawing explanation
Fig. 1 is the utility model front view;
Fig. 2 is the utility model side-view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, 1 be gas-liquid mixed nozzle, 2 are air lines, 3 are fluid pipelines, 4 are air line entrances, 5 are fluid pipeline entrances, 6 are fluid pipeline nozzles, 7 is mixing sections.
The double sleeve pipe of gas-liquid arranges the single or multiple corresponding jet nozzle be made up of gas, the two nozzle of liquid, and internal layer nozzle and water pipe are connected, and outer nozzle and tracheae are connected, and double-deck nozzle and mixing section form this device.Dual-purpose aerating system is formed by the dual-purpose aerator of JAS, pump, blower fan.
The dual-purpose aerator of JAS is the function turn increasing homophase jet on the basis of out-phase (water-gas) aerator (tradition), JAS aerator in water without drive disk assembly, during aeration, in running order the while of pump and blower fan, spray from outer nozzle after the current that internal layer nozzle sprays fully mix with air in mixing section, release micro-bubble, reach aeration and mixing object, close blower fan and only start little pump, now only have water from the ejection of internal layer nozzle, carry out water-water jet and reach stirring action.Its operation result:
1, the transfer of oxygen
Gas-liquid mixed in 1.1 aeration heads, mixing section forms blending phenomenon, air wave shearing-crushing becomes micro-bubble to complete oxygen instantaneously to shift in water, especially water inlet or mud is adopted to be Jetstream fluid, water (organism), mud (microorganism), gas (oxygen) triangular mass transfer carry out rapidly in mixing section with reaction, and this is the quick biochemical reaction and three-phase mass transfer process that occur under given conditions.
The shear effect that 1.2 horizontal-jet miscarriages are raw large forms negative pressure, and the air-flow of surrounding is involved in.
1.3 vapour-liquids of vertically spraying fluid section contact.
Be detained in 1.4 these grooves of microbubble.
1-1,1-2 two functions are unique functions of this aerating system, and therefore this system can obtain higher oxygen dissolved efficiency compared with the aeration mode of routine, energy-conservation nearly 30-50%.
2, be uniformly mixed (conventional aeration mode is unexistent)
2.1 carry out anaerobism with recycle pump is uniformly mixed, injection stream sprays in low velocity fluid, at a high speed with velocity contrast and the energy difference of around low velocity fluid, cause adjacent new liq border and surrounding liquid that violent blending, shearing occur, carry out momentum exchange, the some of the low-yield fluid of border low speed joins sprays in main flow, and is absorbed in the jet expanded, and accelerates.And mix the mixing that the turbulent eddy caused can cause microcosmic
What 2.2 air caused is uniformly mixed, and the air that nozzle sprays into its air-flow gas stripping that rises makes liquid in a large amount of grooves be moved upward, and makes only to need smaller power just can reach Homogeneous phase mixing, the active sludge in aerator tank is not precipitated and maintains floating state.
The dual-purpose aeration of 3.JAS is through Beijing Urban Engineering Design Inst.'s oxygenated clean water test
Oxygenation capacity table
Note: (1) service area 9m 2/ nozzle
(2) air demand: table: flowmeter survey
Mark: tolerance under standard state
As can be seen from test result
The dual-purpose aerator of 5.JAS can save energy 20%-50% than Traditional Method aeration.
6. singly chewing oxygen service area is large 30 times of tradition micro porous aeration head.
7. also betting contest can not occur stopping super 12h under fan condition, and traditional aeration is shut down 1h and is just had blocking may.
8. can realize hydraulic mixing in blowing-out machine situation, prevent anaerobism from producing biogas, to blast, fire hazard.
