Embodiment
Below in conjunction with instantiation and accompanying drawing, the utility model is described further.
The utility model provides a kind of decompression electricity generating device being applied to hydraulic tubing, comprise reduction valve, an electricity generation module is connected in the front end of reduction valve, described electricity generation module principle as shown in Figure 1, structure as shown in Figure 2, comprises body 1, is provided with turbine 3 and the permanent magnet 4 rotated with turbine in body 1, tube wall is wound with for rotate in permanent magnet produce the coil winding of electromagnetic induction, coil winding is connected with rectification module and charging module successively.Preferably, be provided with pilot blade 2 in body 1 front end, rear end is provided with rear guide vane 5.
Reduction valve is connected by stuffing box bearing 6 with body.As shown in Figure 3, reduction valve comprises valve body, is provided with damping hole 7 and guiding valve main valve plug 9 in valve body successively, and the upper end of guiding valve main valve plug 9 is connected with mitre velve 8.
The power resources of turbine are the pressure energies of liquid.Owing to there is pressure p everywhere in body, the p so the crude oil flow through can press to any point on turbine flabellum, the calculating formula according to fluid acting:
W＝Q·p·T·η
In formula: the converting crude oil in W-section of time T is the pressure energy of mechanical energy, the intraday mean flowrate of Q-crude oil, the middle pressure of reduction valve ingress in p-crude oil pipeline, the time of the acting needed for T-calculates, η-pressure energy is converted into the efficiency of mechanical energy.
Then in a period of time, the pressure energy of total W is converted into mechanical energy and is further converted to electric energy.Axial flow generating flabellum will make generating efficiency be guaranteed; Can labyrinth-type excluder be set up before electricity generation module, can prevent there is excessive crude oil leakage between the pipeline of rotation and fixing pipeline.
According to Bernoulli's equation, through the Conversion of Energy of electricity generation module, the pressure energy of crude oil has been utilized a part, but flow is substantially constant.Pressure is now very difficult controlled, and for considering safety and practical application, we need to carry out secondary step-down to crude oil.
Reduction valve is secondary pressure function module, and its principle of work and power is as follows:
If the crude oil pressure after electricity generation module is p
1, the crude oil pressure flowing through damping hole is p
2, the crude oil pressure entering pilot valve oil pocket is p
3, pilot valve set pressure is p
l(can artificially set up).
Pressure is p
1crude oil through damping hole stop after, pressure is reduced to p
2.If now work as p
2≤ p
ltime, the pressure p in pilot valve (guiding valve main valve plug 9 forms pilot valve together with mitre velve 8) oil pocket
3=p
2≤ p
l, show that whole reduction valve outlet pressure meets safety standard, without the need to secondary step-down; Work as p
2>p
ltime, have p equally
3=p
2>p
l, at this moment pilot valve will by p
3back down off-load, afterwards, the crude oil pressure p of guiding valve main valve plug upper-end surface
3the pressure p of lower end surface can be less than
2, therefore guiding valve main valve plug moves, blocks part damping empty, make p
2reduce, reach effect of easing stress.Such leading type pressure reducing circuit control accuracy and the precision of voltage regulation high, be applicable to the large pressure piping that crude oil pipeline is such.It has supplied the uncontrollable shortcoming of crude oil pressure after electricity generation module simultaneously.
Through experiment, generating Be very effective of the present utility model.For Sino-Kazakhstan petroleum transportation pipeline, at least transport crude oil 4,000 ten thousand tons every year, circuit is about 1200km, is a huge engineering.Because fortune oil-piping circuit is long, 1,2 grade of ladder of approach China, different physical features also result in the maintenance problem for oil pressure in pipe in transportation process.If can be by the Conversion of Energy consumed in decompression process electric energy and in addition Appropriate application, will change traditional carried of crude oil mode, the transport volume that crude oil own is huge determines huge generated energy.
In addition, if after carrying out modularization, standardization, systematized design to device, turbine flabellum type selecting is installed, can also be used in gas pipeline; Because this device is that pressure energy is converted into electric energy, namely non-electrical amount is converted into the process of electrical quantities, utilizes this feature, power generation pipeline it can be made the detecting instrument of flow or pressure by us, develops another kind of use.
