Background technique
Stirling engine is to be invented in 1816 by the pastor Luo Bate Stirling (RobertetirIing) in London, so called after " Stirling engine ".Stirling engine is a kind of circulation piston type heat engine of closing, and the meaning of closing circulation is that Working medium gas is kept in cylinder always, by not determining the conversion of hot-cool environment, makes its circular work of expanding with heat and contract with cold.It is a kind of outer combustion-ing engine.
Its advantage of system of application Stirling engine generating is: it does not have the quick-fried acting problem of shake of traditional combustion engine, thereby realized high efficiency, the plurality of advantages such as low noise, low pollution and low operating cost, in addition, it can utilize solar energy, underground heat, chemical energy, nuclear energy equal energy source to make its operation, and, the ambient temperature of equipment is lower, generating efficiency is higher, also has, and power and the efficiency of its output are not affected by altitude.
Its shortcoming of system of application Stirling engine generating is: the sealing area that the dynamic seal (packing) part in its cylinder slides large (seal ring reciprocatingly slides on cylinder wall area), cylinder and each obturator bear High Temperature High Pressure, manufacture it and need very high machining accuracy and expensive manufacture cost, the requirement of its lubrication technology is also quite high, it often occurs because of piston ring scuffing gas leakage phenomenon out of service, so, the system that the Stirling engine of application prior art generates electricity, because also having problems in reliability and working life of its Stirling engine, cause failing extensively universal.
Summary of the invention
Purpose of the present invention, be to overcome the deficiencies in the prior art, a kind of dynamic seal (packing) parts such as conventional piston and piston ring that do not have are provided, and reliability is high, long service life, manufacture cost and the low sound-driving power generation system of the solar heat that includes the liquid piston technology of operating cost.
To achieve these goals, the sound-driving power generation system of solar heat that includes the liquid piston technology provided by the invention is comprised of energy integration system and this two major part of power generation system; Wherein, energy integration system by parabolic reflector, solar tracking transmission device, heat pipe, cold pipe, form; Power generation system is comprised of U-shaped cylinder, float, permanent magnet, positioning resistance plate, retaining spring, coil, rear air pipe, high pressure tank; Energy integration system is by front air pipe, both to be communicated with power generation system, and the Working medium gas in cold pipe, heat pipe, high pressure tank can be hydrogen, nitrogen, helium or air etc., and the worker quality liquid in U-shaped cylinder can be water, oils etc.Be that the liquid of Working medium gas or working medium all is enclosed in above-described member container and moves, be hedged off from the outer world.Unlike the prior art, the present invention includes the sound-driving power generation system of solar heat of liquid piston technology, the dynamic seal (packing) parts such as conventional piston and piston ring are not set in cylinder, the substitute is the liquid piston (being worker quality liquid) be provided with in U-shaped cylinder and cylinder, its tightness is better than prior art, can also long-time non-maintaining operation, its machining accuracy is not high, the cost of manufacturing and the cost of operation are not high yet, the requirement of its lubrication technology is not high yet, because its liquid piston itself is exactly lubricity worker quality liquid preferably, are better than prior art in reliability of the present invention and working life.It is operation like this, the solar tracking transmission device is from the line trace solar direction, the synchronous parabolic reflector that drives is in best reflection angle constantly, the sunlight directive heat pipe focused on, make the Working medium gas temperature fast rise in heat pipe, when temperature rises to 500 ℃, the inside of heat pipe forms between an effective hot-zone, give the of short duration energising of coil of U-shaped cylinder periphery, permanent magnet in float is moved up and down, the liquid promoted in U-shaped cylinder moves up and down, started Working medium gas in cold pipe (between cold-zone), heat pipe (between hot-zone), U-shaped cylinder inner top (between cold-zone), reciprocating in these three intervals, Working medium gas to-and-fro motion output work are come, the liquid piston (worker quality liquid) promoted in U-shaped cylinder is done fluctuation up and down, thereby the permanent magnet driven in float also moves up and down, the motional induction that it is upper and lower the coil generating of U-shaped cylinder periphery, if continue, keep the opposite heat tube heating, it just moves always.
The sound-driving power generation system of solar heat that the present invention includes the liquid piston technology can be applicable to the large-sized solar generating field of MW level, the Stirling engine power generation system of it and prior art is made comparisons, the reliability that can obviously give prominence to present technique is high, low cost of manufacture, operating cost is lower, obturator is almost non-maintaining, extends 3 times working life.In addition, the photovoltaic generation PV system of it and prior art is made comparisons, the more outstanding high advantage of efficiency of the present invention, efficiency of the present invention is 30%, is 2 times of PV system, the cost of operation is 1/3 of PV system.
