A kind of jet stirs anaerobic reactor, and it comprises, anaerobic reaction-pot, and its tank skin top and the bottom are provided with venting hole and posticum respectively; Ejector, in a tubular form, it passes the anaerobic reaction upper end and stretches in the anaerobic reaction-pot, and the ejector lower end is provided with nozzle; The jet recycle pump is arranged in the pipeline that is communicated with ejector; Intake pump is arranged in the pipeline of said jet pump inlet end; A pipeline is also established on anaerobic reaction-pot tank skin top, and this pipeline is connected in the pipeline between said jet recycle pump and the intake pump.
Further, the jet of the utility model stirs anaerobic reactor and also comprises a pair of opening circulating pipe, is arranged in the anaerobic reaction-pot, establishes two opening circulation pipe fixing devices in the anaerobic reaction-pot.
Said stationary installation is to be fixed in some legs of anaerobic reaction pot bottom and to be convexly set in the support on the tank skin.
Said ejector is suspended from said pair of opening circulating pipe top.
Again, said anaerobic reaction-pot tank skin top is provided with vision slit.
Said anaerobic reaction-pot tank skin bottom is provided with drain.
Said nozzle is a tapered hole, and said anaerobic reaction-pot is cylindrical.
Because in the anaerobic reaction process, organic pollutant can produce biogas and nitrogen through decomposing in the sewage mixture, therefore establishes venting hole on anaerobic reaction-pot tank skin top, and gases such as biogas and nitrogen are discharged from venting hole, to guarantee the safety of equipment.Simultaneously, said anaerobic reaction pot bottom is provided with drain, and evacuated tube is connected to this drain, can the sewage emptying in the anaerobic reactor be helped maintenance and maintenance of the equipment.
Said anaerobic reaction-pot possesses performances such as preservative property are good, firm, and can reach more than 20 years its work-ing life.It is anticorrosion to adopt epoxy resin and pitch coal asphalt mixture material to carry out in the anaerobic reaction-pot, and anaerobic reaction-pot takes chlorosulphonation anticorrosion outward.
The utility model is under the centrifugation of intake pump; The sewage mixture is transported to ejector; Ejector passes two opening circulating pipes through nozzle with reaction mixture and vertically is ejected into the anaerobic reaction pot bottom, under the stopping of anaerobic reaction pot bottom, and the reaction mixture anaerobic reaction-pot top of backflowing from two opening circulating pipes periphery; Refluxing gets in two opening circulating pipes again, forms vertical circulation in the jar.In addition, jet recycle pump suction sewage mixture (solidliquid mixture, solid content is not more than 4%) in the anaerobic reaction-pot is given ejector through pipeline transmission, makes the sewage mixture constantly mix repeatedly, mixes more abundant.
The utility model can make the vertically interior circulation in the sewage mixture formation anaerobic reaction-pot, if even the layout overlapped ejectors more in an anaerobic reaction-pot, can form a plurality of vertical interior circulation.The utility model also can be controlled the mixing stirring extent of sewage mixture in the anaerobic reaction-pot through regulating the flow size of jet recycle pump.
The said jet of the utility model stirs anaerobic reactor and can be widely used in the WWT anaerobic stages, can reach more than 98% the removal of nitrogen compound in the sewage.
The beneficial effect of the utility model:
1. the sewage mixture goes out from the nozzle ejection of injector, forms a jar interior vertical interior circulation, has improved anaerobic reaction speed, thereby has improved the clearance to total nitrogen.
2. the mechanical shear stress that produces of the huge turbulent flow that causes from injection stream of sewage mixture; Producing the liquid mixing formula flows; Increased solid-liquid two-phase contacted specific surface area in the anaerobic reaction-pot greatly; Thereby increased the mixing stirring extent, improved anaerobic reaction speed, prevented the generation of deposition of solids simultaneously.
3. can extensively apply to city refuse landfill or incineration plant percolate and handle biochemical stage, the removal of ammonia nitrogen and total nitrogen is all had good effect.
