The present invention is a kind of method and device thereof of capacitance type electricity generation, can be applicable to the field of superhigh voltage DC generating, thermo-electric generation and wave power generation.
Present conventional power generation usage mode is electromagnetic induction generating (is motor rotate its conductor cutting magnetic line generate electricity), but this generation mode is difficult to utilization in special dimensions such as superhigh voltage DC generating, thermo-electric generation and wave power generation.
The invention provides a kind of being easy at superhigh voltage DC generating, the method and the device thereof of the capacitance type electricity generation that special dimensions such as thermo-electric generation and wave power generation use.
The present invention be utilize distance between capacitor plate move or the variation of medium (or dielectric system) realizes generating electricity.The variation of medium and dielectric coefficient can realize with mechanical movement means, is electric energy with other power conversion directly.

The d-polar plate spacing is from m;
In C=(ε s)/(d) formula: s-pole plate area m

ε-capacitor dielectric dielectric constant.
By following formula as seen, when changing polar plate spacing from d(or ε) time, its capacity changes thereupon.Before Blast Furnace Top Gas Recovery Turbine Unit (TRT) is started working, C

Max, show in the formula that the energy storage of C has increased K doubly.At this moment with the K switch closure, capacitor C discharges electric energy by load resistance R, and discharging current is shown in solid line among Fig. 1.
Therefore the electric energy that capacitor C discharges is compared with the electric energy that encourages to C and has been increased K doubly, has realized that promptly mechanical energy (d is increased) has converted electric energy to.Said process carries out continuously, and then load obtains continuous electric energy.
See its basic principle of Fig. 2 as described in Figure 1, wherein capacitor C ' with C " (the replace variable capacitance C) excitation that hockets, release can, make the continuous electric energy of acquisition in the load.
See Fig. 3, capacitor C ', " be made up of moving plate 2,3, stator 4,5, stator all applies bag with the dielectric material to C, and is fixed on the support (shell).Moving plate is tightened up each sheet stack by fixed axis, and axle is made horizontal (axle) to returning toward moving with moving plate, and displacement driven disc both sides gap width is the limit.Prime mover drives concavo-convex 1 rotation of taking turns, and concavo-convexly takes turns effect and makes moving plate and fixed axis do axial motion, realizes that electric capacity is moving, stator spacing d changes.
Thermo-electric generation
Fig. 4 is the structural representation of a group capacitor, it is to utilize the variation of medium dielectric coefficient to generate electricity, pole plate 1, adopt between the pole plate 2 the very sensitive dielectric material of temperature, and structurally be convenient to whole dielectric material and be easy to change, press the connection of Fig. 1 circuit with ambient temperature, when temperature equals a certain high temperature values, dielectric material ε increases to maximum, and this moment, capacity also reached maximum, at this moment with C
oEnergy storage by the D energy storage of charging.Reduce ambient temperature after energy storage reaches maximum, dielectric material ε reduces, and capacitance reduces thereupon, and capacitance energy storage increases, and when increase reached maximum, the K switch closure discharged electric energy to load resistance R.
The process that said temperature changes can be put into the high-temperature region (as warm water with energization electric capacity by mechanical device, be generally less than 100 ℃), go out to place low-temperature space (as air, cold water etc. after the energy storage again, below 30 ℃), ε diminishes to hour, the K switch closure is released energy, and this has just finished the energization exoergic process of one-period.The energization process also can be considered to realize in temperature-rise period.
Thermally sensitive dielectric material adopts barium titanate to make after (mixing with additive) rationally handles, and makes it to have suitable temperature dielectric property, satisfies the requirement of ambient temperature.
Wave power generation
Among Fig. 5, capacitor plate scribbles insulating material, and it is to utilize the variation of medium to generate electricity, and 1,2 on pole plate has a fixed gap 3, places the wave zone with certain device, and when not having wave, electric capacity is made medium with air, and electric capacity was done medium with water when wave was arranged.When water entered between pole plate, the dielectric constant of water was about tens of, and at this moment capacitance reaches maximum, the charging energy storage, circuit such as Fig. 1 are when wave is gone over, water between capacitor plate flows out, at this moment medium becomes air, and the dielectric constant of air is about 1, and at this moment capacitance is minimum, energization reaches maximum, connect K, release energy, promptly realized sending the purpose of electric energy to load resistance R.
