Abstract

The invention discloses a method and a device for preparing hydrogen by an industrial method. The method and the device for preparing the hydrogen by the industrial method are high efficient, simple and used widely and directly perform reaction under the conditions of high temperature, iron, carbon monoxide, carbon and water. Theoretical equations, all in the conditions of the high temperature, comprise that: 3Fe+2H2O(g)= Fe3O4+4H2(g), Fe3O4+2C=3Fe+2CO2<(g)>, Fe3O4+ 4CO (g) = 3Fe+ 4CO2 (g); and auxiliary equations include: C+ H2O(g) = CO(g)+H2 (g), CO2 (g)+ C= 2CO(g). The reactions are all performed at the high temperature; the iron and the water react to generate ferroferric oxide and the hydrogen; the ferroferric oxide and the carbon react to generate the iron and carbon dioxide; or theferroferric oxide and the carbon monoxide react to generate the iron and the carbon dioxide; the carbon and the water react to generate the hydrogen and the carbon monoxide; and the carbon and the carbon dioxide react to generate the carbon monoxide. In the presence of the theory and the conditions, the water can perform the operations of injecting, spraying and atomizing.

Description

Industry law hydrogen and device

Affiliated technical field:

Patent industry law hydrogen of the present invention and device are method and the devices that directly reacts under the condition with high temperature, iron, carbon monoxide, carbon, water.Theoretical equation: 3Fe+2H under hot conditions all ₂O (g)==Fe ₃O ₄+ 4H ₂(g), Fe ₃O ₄+ 2C==3Fe+2CO ₂(g) ↑, Fe ₃O ₄+ 4CO (g)==3Fe+4CO (g) subsidiary equation: C+H ₂O (g)==CO (g)+H ₂(g), CO ₂(g)+C==2CO (g).

Background technology:

At present, known industrial hydrogen production gas method has six kinds:

Sequence number application number title

The preparation method of 1 91110738 high-purity hydrogens

2 02156024 utilize the method for industrial organic waste water biological hydrogen production

The preparation method of 3 03,118,846 one kinds of hydrogen and device

4 200510010383 industrial biological hydrogen preparing bacterial classification Continuous Flow are cultivated and biological hydrogen production gas reinforcement

The method and system of the pure hydrogen of 5 200610015115 preparations

The method of 6 200710070638 preparing hydrogen by sodium borohydride-hydrazine mixed fuel

But six kinds of above method for making requirement condition height, complex process, practical range is little, and abundant inadequately to the utilization of resource, limitation is also bigger.

Summary of the invention:

In order to overcome the high problem of the high waste of current energy present situation more in short supply and industrial energy consumption.This industry law hydrogen and device are a kind of novel simple effectively hydrogen method for makings, and this hydrogen method for making use range is wide, and speed of reaction is fast, continuously direct characteristics.Can directly reduce consumption, and fossil energy is fully used, make the energy structure of fossil obtain better optimize and adjustment fossil energy.

Patent of the present invention solves its technical problem, and the technical scheme that is adopted is: (one) theoretical scheme: 3Fe+2H under hot conditions all ₂O (g)==Fe ₃O ₄+ 4H ₂(g), Fe ₃O ₄+ 2C==3Fe+2CO ₂(g) ↑, Fe ₃O ₄+ 4CO (g)==3Fe+4CO (g) subsidiary equation: C+H ₂O (g)==CO (g)+H ₂(g), CO ₂(g)+C==2CO (g).

(2) embodiment: produce in device according to reaction principle having under the condition that can make iron burn red temperature, iron, coal dust or carbon monoxide, water.(1) in life, uses: device tool using, the whole cooking stove of Sweet natural gas.Automatic horizontal swing waterworks is made a call to an interface on water supply pipe, connect a device that utilizes current to produce kinetic energy.Embodiment: light cooking stove placement level and with it earlier, again the water jet of automatic horizontal swing waterworks is aimed at cooking stove and cooking stove pot supporter, the water speed of ejection is at 0.2m/s-0.4m/s, being the cylindricality diameter is 0.5mm-1.5mm, the scope of swing is according to the drop point of water, the combustion zone that drop point is dropped on the cooking stove gets final product, and water speed is unsuitable too fast, and the water yield is also unsuitable excessive.Behaviour does step: open cooking stove during use earlier, open water valve again, first shutoff valve closes cooking stove again after using up.(2) in industrial use: can utilize the high temperature of industrial generation, the ironware of red heat, the oven-fresh iron blast furnace slag that contains, broken coal dust and carbon monoxide, water or waste water.On the slag of pyritous ironware or iron, spread coal dust or charge into CO (carbon monoxide converter) gas, spray water smoke simultaneously, under different situations, can adjust the sprinkling of water and the ratio of coal dust or carbon monoxide, can produce hydrogen.The hydrogen that produces can be directly used in production also can carry out filtration treatment to the gas that produces, and gas is fed in the aqua calcis carbonic acid gas is removed, and can produce purified hydrogen.

Use range:

Can on the Sweet natural gas cooking stove, use, also can under condition, produce and use, under boiler house, gas furnace, vitriol works, steelworks, coke factory or the like situation, use with high temperature, iron, coal dust or carbon monoxide, water.

Description of drawings:

Fig. 1 contains iron blast furnace slag gas figure processed; Wherein 1. air pressure valve 2. the gas outlet 3. water inlet 4. advance 5. 6. coal dust of waterfog head of coal dust mouth Shower nozzle is 8. 9. 10. iron content high temperature furnace slag or red-hot iron and steel 11 lifting ropes of slag ware of air packing of refractory seals cover 7..

Step: fill earlier iron content high temperature furnace slag or red-hot iron and steel and again the punching of the coal dust high pressure of drying is spilt into. And then the watering mist, between Ratio adjust because of the difference of reactant.

Points for attention: 1. air pressure valve effect: when refractory seals cover on aerial mobile, can enter a small amount of air, a small amount of air exists Fully react in the cover and gases at high pressure that slag produces force air pressure valve to be opened, again the gas extraction that produces has been gone to carry out drying Purified treatment.

Fig. 2 is boiler cooking stove system gas figure; 1. 2. 3. 4. 5. waterfog head of iron and steel net of high pressure intake of coal fire furnace wall of coal fire wherein.

Precaution: spray water with high pressure again when making the iron and steel net red when coal fire is burned to.
