Description

A kind of energy-conservation blast aeration biochemical sewage treatment device

The utility model relates to a kind of blast aeration biochemical sewage treatment device.

The blast aeration device has good operation, equipment characteristics few, easy to maintenance at present, has been widely used in sewage biochemical treatment aspect.But biochemistry pool pucking wind aeration pipe network mostly is and is arranged in parallel usually, with the joining aerator of pipe network is to adopt the duplex pattern, easily rapids shake, wastes energy, the biochemical sludge load-carrying capacity is poor, coefficient of oxygen utilization is low, the equipment vibrations are big, easily loosening, middle micropore easily stops up, work-ing life weak point.

The purpose of this utility model is to improve at the shortcoming of aforesaid device structure, the shake of a kind of elimination rapids is provided, reduce resistance, increase load-carrying capacity, raising coefficient of oxygen utilization, minimizing equipment shake, avoid stopping up, saving the energy-conservation blast aeration biochemical sewage treatment device of the energy.

The utility model adopts following technical scheme to realize: energy-conservation blast aeration biochemical sewage treatment device is by linking with total inlet pipe and being positioned at the blast aeration pipe network at the bottom of the biochemistry pool and forming with joining several aerators of its pipe network.Be characterized in the joining blast aeration pipe network of total inlet pipe be that concentric(al) circles annular arm or center are the loop network that the regular polygon annular arm of same point constitutes, with the joining aerator of its pipe network be water conservancy diversion three cut aerators.

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1--Fig. 4 is the structural representation of blast aeration loop network of the present utility model;

Fig. 5 is the structural representation of water conservancy diversion three cut aerators of the present utility model.

Blast aeration pipe network of the present utility model is that concentric circles annular arm 2 or center are same The loop network that the regular polygon annular arm 2 of point consists of. Link with loop network Total inlet pipe 4 passes with its dimidiation gas main 4 and concentric circles in the middle of loop network The horizontal bent angle of the loop network that annular arm or regular polygon annular arm consist of is less than 90 Degree has radiation perpendicular with its pipe network plane and that link with it at its loop network The property equally distributed, the branched pipe 16 that stretches to the below, this branched pipe 16 and water conservancy diversion three cuts The air inlet pipe 12 of aerator 3 is joined. Total inlet pipe 4 in the loop network, annular arm 2 Increase successively with the caliber of branched pipe 16. The water conservancy diversion three cut aerations that the utility model adopts The cover 11 of device 3 is for partially circular, and its edge is sawtooth. Its cover 11 and deflector 10, air inlet Pipe 12 is fixing. The annular arm 2 (or branched pipe) of one end of air inlet pipe 12 and pipe network passes through Flange 15 links, its other end establish nozzle 14 and be provided with successively gulleting 9, Secondary cut sawtooth 8, three gulletings 13, and lead outer being arranged with of gulleting Stream tube 7 is provided with supporting leg 6 in the bottom of guide shell 7, and fixes with foundation bolt at the bottom of the pond. Whole loop network is also supported with 1 fixing at the bottom of the aeration tank by several supports 5. Like this, Wind enters from total inlet pipe, enters aerator 3 by annular each branched pipe 16 of arm 2 flow paths Air inlet pipe 12, from nozzle 14 ejection, guide shell 7 usefulness supporting legs 6 are fixed at the bottom of the aeration tank 1, Activated sludge is raised up, fully contact backward with the bubble of aerator nozzle 14 ejections On, successively through three saw cut, activated sludge mixes very even with bubble, Rear bubble is raised to the pond face, and so biochemical effect is fine. If the aeration tank floor space is excessive, Can arrange with the unit of a plurality of this structures.

The utility model adopts the loop network structure of concentric circles or regular polygon can eliminate rapids Shake, bent angle is less than the branch vertically downward of equidistant uniform setting on 90 degree and the loop network Pipe can make wind be evenly distributed, and three saw cut of aerator make bubble become more in small, broken bits, Air utilization ratio is increased, and the branched pipe that increased radioactivity is set in addition can be eliminated the aeration life Change the dead angle, the guide shell that arranges has simultaneously increased the hoisting power of activated sludge. Like this, In the constant situation for the treatment of capacity, compare with original blast aerator, can save sky The gas consumption amount, air blast can satisfy production requirement under smaller power. So this practicality is new Type is rational in infrastructure, can eliminate the rapids shake, saves the energy, the service life of extension device. Can Be widely used in industry, sanitary sewage disposal.

Embodiment of the present utility model is as follows:

At the bottom of the circular aeration tank of 7 meters of diameters, total inlet pipe 2 crosses three concentric(al) circles arms for DN200 pipe level and connects successively, at the bottom of being fixed on the pond by bearing, the ring pipe center is all at same horizontal plane, at the bottom of the pond 840 millimeters, interior ring diameter is 2 meters, and interior ring arm is DN50, uniform 2 take-off pipes of its vertical lower; Interior ring diameter is 4 meters, middle ring arm is DN100, uniform 4 take-off pipes of its vertical lower, 6 meters of outer ring diameters, the outer shroud arm is DN150, its uniform 6 take-off pipes in below, take-off pipe is DN32 and communicates with arm, and take-off pipe is provided with DN32, the Pg10 standard flange apart from 240 millimeters places of arm plan range, connect fixing with the aerator inlet flange, the aerator inlet pipe is DN32, and aerator comprises and its connection fixed guide shell and supporting leg that height overall is 600 millimeters, at the bottom of the anchoring bolt fixed spool, thereby finish assembling.Wind is mixed three times by saw cut with the mixed solution that guide shell elevates by the nozzle ejection by the steady unobstructed ground warp arm of total inlet pipe, take-off pipe, aerator inlet pipe, and up-flow is to the pond face.
