A kind of adjustable jet aeration device
(1) technical field
The present invention relates to water technology, is exactly a kind of adjustable jet aeration device specifically.
(2) background technology
Jet-flow aeration is as a kind of aeration aerating method; Its effect is not only as a kind of bubble diffusion oxygenate apparatus (like the various air-diffusers in the blast aeration); Can not regard a kind of mechanical aeration equipment merely as; But fall between, utilize bubble diffusion and two effects of hydraulic shear to reach the purpose of aeration and mixing.In fact, in the activated sludge process Waste Water Treatment, because the mixture that adopts waste water and activated sludge usually as working media, quite violent immixture takes place in the trunnion at ejector after sucking air.This immixture is being carried out turbulent fluctuation diffusion and energy exchange and the gas-liquid-solid three alternate transfer processes between gas-liquid-solid (activated sludge) on the one hand, and also having outstanding more is to occur in the effect biologically between this three of organic matter in the molecule that " cut " very tricklely by at a high speed violent turbulent fluctuation bubble, activated sludge and the waste water (liquid phase).Increase the Surface Renewal rate and the adsorption surface area of activated sludge greatly, thereby make the tiny cotton-shaped physical efficiency of activated sludge the sufficient suction-operated that contacts arranged, adsorption capacity is improved greatly with oxygen and the organic matter in the waste water in the bubble.This is that other type aerator institute is inaccessiable.
In the organic wastewater aerobe treating apparatus, will use jet aerator usually and realize gas-liquid mixed, traditional jet aerator needs devices such as air chamber, mixing chamber, anemostat, complex structure, and it is not high to hold tolerance, mixing efficiency under the arm, and cost is high.
(3) summary of the invention
The object of the present invention is to provide a kind of simple structure, good seal performance, gas-liquid mixed is effective, and is stable, with low cost, regulates flexible adjustable jet aeration device.
The objective of the invention is to realize like this: it is made up of jet units 14 and suction unit 15, and suction unit 15 is arranged on the vertical part of jet units 14.
The present invention also has following technical characterictic:
(1) described jet units 14 comprises jet pipe 3, Pressure gauge 10, adjustable nozzle 8 and vent valve 11; The horizontal component of jet pipe 3 is provided with dress Pressure gauge 10 and vent valve 11; Jet pipe 3 one ends are installed adjustable nozzle 8, between jet pipe 3 and the adjustable nozzle 8 for being threaded or clamp connection.
(2) described suction unit 15 comprises air intake duct 2, regulating handle 1, flange chassis 4, adjustable shower nozzle 8, scale 9, rigidity packing ring 12, blind flange 6 and mounting platform 13; Air intake duct 2 passes jet pipe 3 and mounting platform 13 is set at the place of passing and is provided with in the accent and installs; Air intake duct 2 tops are provided with regulating handle 1 and scale 9; Supporting different size rigidity packing ring 12 and blind flange 6, sealing between blind flange 6 and the air intake duct 2.
A kind of adjustable jet aeration device of the present invention; Compare with traditional ejector; Not only saved devices such as air chamber, mixing tube, anemostat, and simple in structure, can change adjusting flexibly; In actual installation and operation are debugged, can be according to ruuning situation and each spot size of needs adjusting device.Installation and Debugging are convenient, can effectively avoid unexpected waste.
(4) description of drawings
Fig. 1 is the view of installing and using of the present invention;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is a partial enlarged drawing of the present invention;
Fig. 4 is a nozzle cutaway view of the present invention.
(5) specific embodiment
For example the present invention is further specified below in conjunction with accompanying drawing.
Embodiment 1.In conjunction with Fig. 2, a kind of adjustable jet aeration device of the present invention, it is made up of jet units (14) and suction unit (15), and suction unit (15) is arranged on the vertical part of jet units (14).
The present invention also has following technical characterictic:
Described jet units (14) comprises jet pipe (3), Pressure gauge (10), adjustable nozzle (8) and vent valve (11); The horizontal component of jet pipe (3) is provided with dress Pressure gauge (10) and vent valve (11); Jet pipe (3) one ends are installed adjustable nozzle (8), between jet pipe (3) and the adjustable nozzle (8) for being threaded or clamp connection.
Described suction unit (15) comprises air intake duct (2), regulating handle (1), flange chassis (4), adjustable shower nozzle (8), scale (9), rigidity packing ring (12), blind flange (6) and mounting platform (13); Air intake duct (2) passes jet pipe (3) and mounting platform (13) is set at the place of passing and is provided with in the accent and installs; Air intake duct (2) top is provided with regulating handle (1) and scale (9); Supporting different size rigidity packing ring (12) and blind flange (6), sealing between blind flange (6) and the air intake duct (2).
Embodiment 2, in conjunction with Fig. 2, and a kind of adjustable jet aeration device of the present invention; Described jet pipe (3) one termination feed tubes, liquid is gone into jet pipe by the feed tube high velocity stream, at jet pipe air intake duct (2) is housed partly vertically; Air intake duct (2) passes jet pipe (3) and is provided with air intake duct mounting platform (13) at the place of passing; And be provided with in the accent and install, air intake duct (2) top is provided with regulating handle (1), can contrast scale (9) and accurately regulate the air intake duct height up and down.Can regulate the air intake duct bore according to different size rigidity packing ring (12) and blind flange (6); Packing (5) with spunyarn, asbestos material between blind flange (6) and the air intake duct (2) twines sealing; Jet pipe (3) other end is equipped with adjustable nozzle (8), through install the different size nozzle can adjust nozzle diameter and and air intake duct between spacing e.During use this device is installed in the injection circulation reactor top, like the structure of expression among the figure, liquid is gone into jet pipe by the feed tube high velocity stream, quickens to inject reactor at the nozzle place, produces negative pressure by the current high velocity jet, and a large amount of air are sucked by air intake duct.Under the acting in conjunction of current and air-flow, make nozzle form high speed turbulent shear district, be to suck air dispersion to become minute bubbles.But lean out nozzle length through regulating handle up-down adjustment air intake duct.Air intake duct is by the common fixing seal of flange base (4), blind flange (6) and packing (5).The adjustment centralising device makes air intake duct centering, guarantees good air-breathing and dispersion effect.
