Description
Technical field
The utility model relates to a kind of sewage disposal accessory, particularly a kind of dry type ejector.
Background technology
The aeration mode that in sewage disposal, the aerobic treatment stage adopts is modal is dish (pipe) aeration and two kinds of modes of jet-flow aeration, and the aerator that its mid-game (pipe) aeration adopts comprises plate-type aerator, tube aerator, boring aeration pipe etc.; The jet-flow aeration mode mainly be take submersible type aerator mode as main; The aerator that blast aeration adopts generally adopts ethylene propylene diene rubber (EPDM) diaphragm and supporting check-valves, retainer plate, aerator pallet and air blast to form; Provide origin by air blast, utilize opening of a large amount of spaces on the elastic reaction of aerator diaphragm and diaphragm, produce the micro-bubble of 1 ~ 3mm in sewage, sewage is carried out to oxygenic aeration.The submersible type aerator divide do not need supporting air blast with two kinds of forms of the supporting air blast of needs, aerator and motor or immersible pump integral structure, the negative pressure produced in pipeline by jet at a high speed, then aspirated air formation aeration process by the pipeline directly contacted with atmosphere.
Plate-type aerator, tube aerator generally all adopts bottom being fixed on aerobic biochemical pool after aerated conduit is connected, for conventional municipal sewage and low-concentration industrial wastewater treatment, because the upper space of aeration plate (pipe) is very little, in sewage, easily stop up, aging, come off so that the inhomogeneous situation of aeration, need periodic maintenance to change, and each the replacing generally all needs sewage in biochemistry pool and activated sludge are carried out to emptying, the Maintenance and Repair workload is large, operating environment is disliked slightly, also can waste the activated sludge that system cultivates out simultaneously, need to again be cultivated and be tamed.Although the mode of boring aeration pipe does not exist serious obstruction and aging situation, but because the aeration eyelet is larger, aeration efficiency is lower, can waste the more energy, so general only for the occasion of pretreatment aeration and mix and blend, be not suitable for aerobic treatment.Conventional efflux aerator is due to aerator and electric (immersible pump) integral structure, in general sewage without long fibre shape material, not there will be the puzzlement of stopping up and coming off, be applicable to the aeration oxygen supply of high sludge concentration occasion, but generally between 150 ~ 1000kg, install and safeguard comparatively difficulty due to motor and aerator, the general applicable depth of water of this aerator is between 0 ~ 6m simultaneously, be not suitable for the biochemistry pool Air Exposure of the higher depth of water, and price is comparatively expensive.
The utility model content
Goal of the invention: for the deficiencies in the prior art, the utility model discloses a kind of simply lightly, long service life, safeguard to be easy to the dry type ejector
Technical scheme: the utility model discloses a kind of dry type ejector, comprise, the hydraulic cyclone section be communicated with successively, acceleration jet segment and jet diversion section; Described acceleration jet segment sidewall is provided with the mixing wastewater with air section; Between described acceleration jet segment and jet diversion section, by internal-screw ball valve, be communicated with.
Wherein, between described hydraulic cyclone section, acceleration jet segment and jet diversion section, be threaded connection; Safeguard that simply, accessory is replaced convenient.
Wherein, between described acceleration jet segment and jet diversion section, by internal-screw ball valve, be communicated with, can be in the situation that ball valve to be blocked current, dismounting dry type ejector is safeguarded or is worse; Can not overhaul aerator because of replacing needs emptying tank body (pond body) to cause the biochemical system activated sludge blow-down pit body that runs off even to process.
Wherein, establish the stream helical accelerator in the hydraulic cyclone section, reasonably accelerate jet, helical structure and can form efficient jet-flow aeration effect in conjunction with rational air water ratio, bubble diameter is between 1 ~ 2mm; 8m depth of water oxygen-transfer efficiency can reach 35% ~ 40%.
Hydraulic cyclone section flange end is connected with external water circulating pump, for the jet-flow aeration process provides enough quantity of circulating water, built-in 4 spinning disks, can carry out the eddy flow acceleration to water inlet, velocity in pipes is generally at 3 ~ 6m/s, the other end is connected with the acceleration jet segment by external screw thread, accelerate to form high-speed jet and enlarge aperture at outlet section by the convergent bore in ejector, the micro-bubble that the negative pressuren zone of formation and eddy flow state can form 1 ~ 2mm by the effect of entrainmenting, shear, rotating by the air that comes from mixing wastewater with air section flange port mixes with water.By the jet diversion section, import in tank (case) body again; Jet diversion section and tank (case) body adopts downward 30 ° of inclinations to be welded and fixed; Each intermodule of dry type ejector all is threaded connection, and mixing wastewater with air section flange is connected with air blast.Internal-screw ball valve can by opening and closing be used for cutting off with tank (case) body between be connected.
Beneficial effect: the disclosed dry type ejector of the utility model, simple in structure, easy to maintenance, long service life.
The accompanying drawing explanation
The structural representation that accompanying drawing 1 is the dry type ejector.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further explained.
The utility model discloses a kind of dry type ejector, comprise, the hydraulic cyclone section 1 be communicated with successively, acceleration jet segment 2 and jet diversion section 5; Described acceleration jet segment 2 sidewalls are provided with mixing wastewater with air section 3; Between described acceleration jet segment 2 and jet diversion section 5, by internal-screw ball valve 4, be communicated with.
