Description
Technical field
The utility model relates to a kind of draft tube, especially a kind of sewage treatment plant tail water power generation corner bevelling pipe discharge structure.
Background technique
Tail water energy recovery system is as hydraulic generator machine equipment spin-off, when designing tail water, traditional design be from
Diffusion process of the circle cross section to rectangular cross section gradual change.Traditional design scheme is all relatively time-consuming in production and installation process to take
Power, duration are longer；The abundant recycling that cannot guarantee the tail water energy well during use leads to a part of energy wave
Take.Therefore it needs that existing traditional draft tube design scheme is improved and optimized, reaches Dual high-efficiency energy conservation.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of sewage treatment plant tail water power generation herein
Corner bevelling pipe discharge structure can overcome the existing most of existing circle cross section side of crossfading into sections using corner bevelling pipe drainage pattern
Draft tube problem encountered can solve the problem that energy recovery is insufficient, water flow is not smooth.With high efficiency, good
Good head and changes in flow rate adaptability and operation stability, finally realize energy-efficient purpose.
The corner bevelling pipe discharge structure the utility model is realized in this way a kind of sewage treatment plant tail water generates electricity, feature exist
In：With Taper Pipe A, elbow, Taper Pipe B, telescopic joint, valve and Taper Pipe C；The discharge structure is installed using sectional making, cone
Pipe A, elbow, Taper Pipe B, telescopic joint, valve and Taper Pipe C are sequentially connected and any section is circle；Cross-sectional area is from water
Start at machine, constantly becomes larger；Intermediate connecting bend, until as by-pass line cross-sectional area；What is directly connect with water dispenser is
Taper Pipe A after connecting bend, and connects Taper Pipe B, and circle cross section area constantly becomes larger, until close to by-pass line section.Round drainpipe
Not only forming, beauty, convenient for by-pass line abutting joint, but also in energy utilization, recycling be better than the rectangular tail water of gradual change
Pipe.Higher tail water utilization rate can be reached.
According to sewage treatment plant tail water described in the utility model power generation corner bevelling pipe discharge structure, it is characterised in that：The cone
Pipe A import size is 650mm；The center radius of the elbow is 1297.2mm to 1317.2mm；The Taper Pipe C center line
With valve, telescopic joint center line at 7.88o to 8.08o.
What is directly connect with water dispenser is tail water taper straight tube, after connecting bend, and connects conical pipe, circle cross section area is continuous
Become larger, until close to by-pass line section.It is advanced by the application world based on existing most of generating equipment draft tubes
Fluid flow analysis technology CFD, which flows the tail water of dedicated energy recovery system, to be analyzed and is optimized and in real machine test
It is verified, final optimization pass goes out a kind of new energy recovery system draft tube.This practical feature is any section of draft tube
It is circle, cross-sectional area constantly becomes larger since at water dispenser, until as by-pass line cross-sectional area.The utility model
Its improvement is that, to the drainage pattern of the diffusion process of rectangular cross section gradual change, the row of conical bend pipe will be optimized for from circle cross section
Water form.
The utility model has the advantage of：By improving and optimizating, most of existing tail water energy recovery systems are overcome
Tail water energy utilization rate it is low, flow obstructed problem.It is more logical convenient for Tail water reuse that gradual change square tube is improved to gradual change round tube
Freely；Convenient for more preferably recycling unused energy.It is verified by using computer fluid flow analysis technology CFD and real machine test,
Develop the tail water form of tubes for most adapting to head size and variation, changes in flow rate that energy recovery system is faced.Guarantee
High efficiency, the stability of source recovery system, the final purpose for realizing high efficient energy sources recycling.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram
Wherein：Taper Pipe A1, elbow 2, Taper Pipe B3, telescopic joint 4, valve 5, Taper Pipe C6.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing 1, technical solution in the embodiment of the present invention into
