Description
Technical field
A kind of pipeline water energy recovery device, relates to the recoverable device of piping liquid pressure.
Background technique
At present, in disclosed documents and materials, that waterpipe is installed water energy recovery device generate electricity is a lot, and the critical piece of this water energy recovery device is runner, is rotated by water impact runner, thus drive electrical generators generating.The pipeline that such device is higher for some pressure, flow is larger, energy recovery efficiency is higher, is proper.But when pipe diameter less (caliber 50 ~ 100mm), fluid pressure can less (head 20 ~ 80m), can lose more energy, reuse efficiency is lower, is generally less than 50%.
Summary of the invention
Problem to be solved in the utility model is exactly for above not enough and provide a kind of pressure piping for pipe with small pipe diameter, low water head, can effectively reduce pressure, device that energy recovery rate is high.Its technological scheme is as follows:
A kind of pipeline water energy recovery device, its key technology is to comprise volute room and diversion chamber, and the spiral case of volute room fixes diversion chamber, casing installs rotating shaft, rotating shaft one end connects runner, and the other end drives generator, along the circumferential direction uniform some drainage lumens in diversion chamber, namely drainage lumens is the runner that fluid flows through, runner is divided into leading portion runner and back segment runner, and leading portion Flow area convergent, communicates with volute room, back segment Flow area is constant, communicates with runner; The water outlet of runner connects drain pipe.
Compared with prior art, the utility model has following beneficial effect:
1, this decompressor is provided with volute room and diversion chamber, and during work, high-pressure liquid is entered in the volute room that an area reduces by pipeline, can make to enter the fluid distrbution of diversion chamber like this evenly.Utilize volute room and diversion chamber that the pressure energy that liquid has is converted to swiftly flowing speed energy.After liquid leaves diversion chamber, flow into runner channel, according to Theories of Cascades, the high speed kinetic energy of current is converted to the rotating mechanical energy of runner, while effectively reducing pipeline pressure, can the pressure energy of fluid in high efficiente callback pipeline, with synchronous generator direct connection, generated electricity by rotating shaft drive electrical generators.Experiment is normal runs generating about 300 days, energy recovery efficiency >=65%.If adopt induction generator generating, work runner rotating speed is reduced to 1530r/min or lower time, energy recovery efficiency can further improve, and can reach about 70%.
2, diversion chamber inner flow passage is divided into two sections, and leading portion is area convergent runner, and when fluid is by this section of runner, along with the continuous reduction of Flow area, according to D.Bernolli equation, fluid-flow rate constantly increases; Back segment Flow area is constant, and width direction is parallel structure, main current stabilization and drainage, ensures that liquid enters in runner with correct angle.
3, the utility model is mainly applicable to the recovery that the heating of tall building etc. supplies water return pipeline upward pressure energy, but is not limited thereto.Device internal flow working medium is heating water return or clear water.The utility model is applicable to head ratio lower (20 ~ 120m is preferably 60m, 80m, 100m and 120m), pipe diameter smaller (50 ~ 150mm), the smaller (50 ~ 150m of flow
3/ h, preferred flow section mainly contains 50m
3/ h, 100m
3/ h and 150m
3/ h), range of flow is wider, the occasion of generated output little (about 10kW).
4, the utility model compact structure (size of whole decompressor is about 500mm × 500mm × 300mm, does not comprise master section), simply, volume is little, and machining is convenient, and mounting or dismounting are convenient, and installation and maintenance are easy.
5, when blade is ruled surface, non-distorted type blade, easy to process; When blade is curved surface, processing is slightly complicated, but Flow Field Distribution evenly, pressure pulsation is less.
6, when the operating conditions such as flow, head changes greatly, only need adjust the parameter such as diversion chamber reference angle, drainage lumens sectional area and drainage lumens number, runner bucket number, blade angle (as shown in table 1, table 2), coming of new of laying equal stress on diversion chamber and runner, volute room and drain pipe do not need to do any change, thus reduction manufacture cost, and facilitate producing in serial form, and distributed networking generating can be carried out.

Embodiment
See Fig. 1 ~ Figure 11, the utility model comprises volute room 1 and diversion chamber 2, and the spiral case of volute room 1 is bolted diversion chamber 2, casing is installed rotating shaft 6, rotating shaft 6 one end connects runner 3, and the other end drives generator, along the circumferential direction uniform some drainage lumens 7 in diversion chamber 2, namely drainage lumens is the runner that fluid flows through, runner is divided into leading portion runner 8 and back segment runner 9, and leading portion runner 8 area convergent, communicates with volute room 1, back segment runner 9 area is constant, communicates with runner; The water outlet of runner 3 connects drain pipe 5.Bolt Connection together with cast inblock, can be passed through after also can casting separately in drain pipe 5 and volute room 1.
During use, volute room 1 is by Flange joint intake pipe, and drain pipe 5 is by Flange joint outlet pipe.
The circumferential cross-section of described drainage lumens 7 chamber is rectangle (as shown in Figure 4), conveniently carries out Milling Process.
Described drainage lumens 7 is the distribution in circular row palisade in diversion chamber.
Described drainage lumens 7 aligned fashion (as shown in Figure 5) or be interspersed (as shown in Figure 6) in diversion chamber.
Described runner 3 comprises wheel hub 10, blade 11 and wheel cap 12, and wheel hub 10 and wheel cap 12 install blade 11 by axle or screw.
The sectional shape 15 of described blade 11 is illustrated in figure 9 the class crescent shape of front blunt metacone.No matter blade surface is ruled surface or curved surface, and its sectional shape is identical, is all the class crescent shape of front blunt metacone.
Blade 11 comprises into water limit 13, outlet edge 16, working surface 17 and the back side 14.The each surface of blade (water inlet limit 13, outlet edge 16, working surface 17 and the back side 14) can be processed as ruled surface as shown in Figure 10, but not meander configuration blade, easy to process like this; The each surface of blade (water inlet limit 13, outlet edge 16, working surface 17 and the back side 14) also can be processed as curved surface as shown in figure 11, like this processing slightly complexity, but Flow Field Distribution evenly, pressure pulsation is less.
