Fig. 4 is the schematic diagram of voltage switching device.

Among the figure, 1-atmospheric discharge device, 2-voltage switching device, 3-capacitance type electricity generation machine, 4-load.

Five, embodiment:

The present invention is converted into the device of electric energy for a kind of Wave energy with atmospheric pressure, referring to Fig. 1, comprise atmospheric discharge device 1, voltage switching device 2 and 3 three parts of capacitance type electricity generation machine, the input of voltage switching device 2 links to each other with the earth with atmospheric discharge device 1, the output of voltage switching device 2 links to each other with the input of capacitance type electricity generation machine 3, and the output of capacitance type electricity generation machine 3 links to each other with load 4.Atmospheric discharge device 1 is wanted and negative electrical charge can be discharged into the atmosphere, and obtains positive charge simultaneously from atmosphere; Voltage switching device 2 is one group of switching circuit, its function is to be implemented in the Δ T time to give that to provide voltage difference to capacitance type electricity generation be the voltage input of V, provide voltage to be-the voltage difference input of V and give to capacitance type electricity generation in the next Δ T time, so circulation, thus make capacitance type electricity generation machine 3 obtain the voltage of alternation; Capacitance type electricity generation machine 3 is used for the voltage of alternation is converted into electric current output.This Blast Furnace Top Gas Recovery Turbine Unit (TRT) need obtain energy from the voltage difference between atmosphere and the earth, should be accompanied by the strong electric discharge phenomena of appearance in atmosphere in this process, as the corona discharge phenomenon;

The most basic equivalent schematic diagram of capacitance type electricity generation machine as shown in Figure 2, the capacitance type electricity generation machine is made up of two electric capacity and a rectification circuit, the voltage that this circuit just can be finished alternation is converted into electric current output.

If the voltage between two inputs is V, the voltage in the capacitor C is u, and the resistance of external circuit is R, and then the electric weight Q in the capacitor C is

Q＝C×u

Thereby the electric current I in the circuit is

$I=\frac{\mathrm{dQ}}{\mathrm{dt}}=C\frac{\mathrm{du}}{\mathrm{dt}}$

Wherein u should satisfy

2u+IR＝V

Solve thus

$u=\frac{V}{2}+\mathrm{aexp}(-\frac{2t}{\mathrm{CR}})$

Wherein a is a certain constant.Solve by following formula

$I=C(\frac{1}{2}\frac{\mathrm{dV}}{\mathrm{dt}}-\frac{2a}{\mathrm{CR}}\exp (-\frac{2t}{\mathrm{CR}}))$

Can see that after a period of time, output current is

$I=\frac{\mathrm{<figure-callout\; id="2"\; label="C"\; filenames="A20081015045800111.png"\; state="\{\{state\}\}">C</figure-callout>}}{2}\frac{\mathrm{dV}}{\mathrm{dt}}$

Power output is

$P=\mathrm{IV}=\frac{\mathrm{<figure-callout\; id="2"\; label="CV"\; filenames="A20081015045800111.png"\; state="\{\{state\}\}">CV</figure-callout>}}{2}\frac{\mathrm{dV}}{\mathrm{dt}}$

As seen as long as voltage has fluctuation, this engine just has electric current output, and the voltage in the atmospheric electric field is constant basically, and it is bigger therefore to need voltage switching device to obtain

The circuit theory diagrams of voltage switching device as shown in Figure 4, K switch in the Δ T time with the conducting of A end points, and in the next Δ T time with the conducting of B end points, the rest may be inferred, the voltage of an alternation will appear in output.In the present invention, an end of voltage switching device should link to each other with the earth, provides negative electrical charge by the earth, and the other end should link to each other with the atmospheric discharge device.The output of voltage switching device should be connected with the input of capacitance type electricity generation machine.

The atmospheric discharge device is made up of a row or multi-row pin, link to each other by conductor between each pin, then by lead and voltage switching device input+end or-end links to each other, the pin end of atmospheric discharge device should be placed on high aerial, high more good more, should be able to guarantee to produce the atmospheric electricity halo effect highly at least.Can take some measures as increasing humidity, employing ultraviolet irradiation, use radioactive source etc. and reduce the difficulty that produces corona effects.

Under ideal case, the power output of this Blast Furnace Top Gas Recovery Turbine Unit (TRT) has two kinds of situations:

1. work as the atmospheric discharge device and corona effect occurred, this moment, atmosphere electric capacity was breakdown, and theoretical generated output is

$P=\frac{{\mathrm{<figure-callout\; id="2"\; label="CV"\; filenames="A20081015045800111.png"\; state="\{\{state\}\}">CV</figure-callout>}}^2}{2\mathrm{\&Delta;T}}$

Wherein V is the voltage difference before and after the discharge of atmospheric discharge device, the situation when this situation is the Blast Furnace Top Gas Recovery Turbine Unit (TRT) operate as normal.

If 2. corona effect does not appear in the atmospheric discharge device, just must consider the influence of atmosphere electric capacity, because atmosphere electric capacity has only several pF, it is regarded as an electric capacity of connecting with the capacitance type electricity generation machine, so theoretical generated output is

$P\&ap;\frac{C_0{\mathrm{<figure-callout\; id="2"\; label="V"\; filenames="A20081015045800111.png"\; state="\{\{state\}\}">V</figure-callout>}}^2}{\mathrm{\&Delta;T}}$

Wherein V is the voltage difference between atmospheric discharge device and the earth, C ₀Being atmosphere electric capacity, because this value is very little, is 10 ^-12The F magnitude causes the power output of this moment very little, and this situation is the situation that should avoid in the design.

After corona effect appears in sparking electrode, charge neutrality has taken place in some negative electrical charges on the electrode and the positive charge in the atmosphere, cause electrode and atmospheric electricity pressure reduction to descend, corona effect stops, and after the Δ T time, sparking electrode is connected with another one electric capacity, this electric capacity is owing to be connected with the earth in the last Δ T time, have more negative electrical charge, this moment, these negative electrical charges will add to sparking electrode, made sparking electrode the pulsed discharge phenomenon occur.
