Embodiment
Consult shown in the accompanying drawing 1,3: fibre bundle (1) is " solar fibre-optical conduction energy collection array " patent No.: 200510100654.2 light energy output block, it can put together large-area solar radiant energy with the form of cumulative light beam (2) and be radiated on the coal dust (6) of Reaktionsofen (3) the inside by the light inlet window (4) that is arranged on Reaktionsofen housing top.Reaktionsofen (3) can be higher than operation under the atmospheric pressure state, also can move under the normal atmospheric pressure condition, adopts the normal atmospheric pressure condition in the present embodiment.Light inlet window (4) is that the luminous energy of projection is absorbed in a large number by coal dust with optics glass one-tenth, because its good light transmission and coal dust (6) are similar to the character of perfect black body.
According to the straying quatity of the quantity of coal dust and water vapour, suitably select the condensing apparatus quantity and the condensing apparatus total area of " solar fibre-optical conduction energy collection array ", fibre bundle (1) that enough solar radiation energy just can be provided, make the temperature of coal dust rise to 1273k and satisfy the required absorption of reaction of carbon reduction water vapour heat, make to react and proceed.
Consult shown in the accompanying drawing 5, XP be thermopair (7) it with the temperature transition of impression become electromotive force, through sending into the differentiating amplifier that BG1, BG2 form after the electric bridge compensation, regulate the resistance of RT and select the differentiating amplifier trim point.The unbalance BG4 conducting of differentiating amplifier, rly. M adhesive, contact m when the XP temperature reaches 1273k
1, m
2Closed steam valve (26) is that the D energising is opened, and water vapour just sprays from nozzle (6) through steam valve (26) from boiler (24); When the carbon in the coal dust during by the only remaining impurity of reaction consumes, because of reaction stop in the stove that temperature rises and when surpassing the 1273kk certain limit, so voltage comparator LM108 just has voltage output rly. P adhesive, contact P1 closure, the running of MD fire door motor (10) forward to open fire door (9).Removal of contamination, add close a switch after the coal dust K, its normally closed contact k again
1, k
2Disconnection, normally opened contact k
3, k
4Closed fire door motor antiport is closed fire door (9) and is proceeded said process then.L1, L2 are the wiring scheme of fire door motor.L3, L4 are the wiring scheme of piston motor.
Because the reaction of carbon reduction water vapour need absorb heat, when being reduced to 1273k under the temperature of coal dust, from the above rly. M will cut off the power supply, contact m
1, m
2Disconnection, controller (25) are closed the just continuation rising of temperature that stops to spray into water vapour, coal dust so stop to export control current steam valve (26).So the reaction in the Reaktionsofen (3) maintains on this temperature, reaction will continue.Coal dust in the Reaktionsofen (3) is generated as H under this temperature and from the reaction that nozzle (6) sprays into water vapour
2, its reaction formula of CO is as follows:
C
Red-hot+ H
2O=H
2+ CO (1)
(be heated to 1273K
)
Because of so the resultant of reaction in the Reaktionsofen is increase, the resultant of reaction H of gas along with gas volume
2, CO and the part remainder water steam venting hole (5) that can be provided with from Reaktionsofen top flows into condenser (11).
Normal temperature, water vapour can condense into water condenser and the water shoot (13) that is provided with below the condenser flows in the pond (14) because temperature will drop to from the high temperature of hundreds of degree in condenser.So because the gas that water shoot stretches in the underwater condenser of pond can not flow in the atmosphere H
2, CO can only flow into knockout tower (15) from inlet mouth (21).
The working process of knockout tower is as following: consult shown in the accompanying drawing 4, upper piston (18), lower piston (28) structure is identical, it is provided with pore (27), pore is provided with and closes the valve of opening as the time spent as external force (23) usually under spring action; The centre of last lower piston is provided with the screw that matches with rib-loop on the screw mandrel (19).The starting position of lower piston is in knockout tower: the both sides and the thimble (22) that lay respectively at thimble (22) are opened valve (23) one by one.So the space of two portions up and down of piston (18), (28) communicates at this moment.Be moving sets between piston and the knockout tower inwall.
Because the molecular weight of carbon monoxide, hydrogen is respectively 28 and 2 to differ 14 times, so their proportion also differ 14 times at normal temperatures and pressures these two kinds of gases can natural separation under action of gravity hold, lighter hydrogen can be stayed the upper strata, heavier carbon monoxide will accumulate in lower floor.By reaction formula (1) as can be known, hydrogen and carbon monoxide have identical mole number in resultant of reaction, they have identical volume so both line of delimitation roughly in the mid-way of tower under standard state.
So when closed piston motor (20) the forward running of Closing Switch J, contact j1, drive by screw mandrel (19) stop near the mobile round about simultaneously T﹠B that moves to knockout tower up to last lower piston of upper and lower piston, piston has left thimble (22) so valve (23) is closed automatically during this, last lower piston will be got rid of hydrogen and carbon monoxide respectively from hydrogen pipe (16), carbon monoxide pipe (17), inlet mouth (21) continues to flow into hydrogen and carbon monoxide in tower simultaneously; Closed then reverser Z, piston motor (20) antiport, by lower piston in screw mandrel (19) drive move in opposite directions simultaneously, go up lower piston will get back to starting position, valve (23) again by thimble (22) reopen, stopcock J and Z piston motor (20) shut down.
Along with the hydrogen of motion repeatedly of going up lower piston in the knockout tower and carbon monoxide are constantly got rid of from hydrogen pipe (16), carbon monoxide pipe (17).The effect of backstay is to prevent that piston from rotating, guaranteeing that the relative position of pore on the piston and thimble (22) is constant in the process that moves up and down.
Carbon monoxide be byproduct of the present invention, it be a kind of geseous fuel of high combustion value be again the important chemical starting material.
Consult shown in the accompanying drawing 2: the difference of it and accompanying drawing 1 is cancellation knockout tower (15), directly draws the water-gas of being made up of hydrogen and carbon monoxide from the other end of condenser (11).
See that from energy point of view hydrogen and oxygen combustion and carbon monoxide and oxygen combustion all are thermopositive reaction:
2H
2+O
2＝2H
2O
2CO+O
2＝2CO
2 
(2), their heat release total amounts of the oxidizing reaction of (3) two formulas reach 1043k/mol and heat that carbon reduction water vapour reaction is absorbed to have only 131.3kj/mol, ratio between two be 7.96 times.So the present invention has very high energy input-output ratio.
