The system that a kind of refuse pyrolysis plasma gasification prepares hydrogen fuel
Technical field
The utility model relates generally to a kind of technology of refuse pyrolysis, and in particular to a kind of refuse pyrolysis plasma gasification system
The system of standby hydrogen fuel.
Background technology
Garbage disposal problem has become China after institute face after energy crisis, water pollution control, industrial waste treatment at present
The environmental problem of the another item sternness faced.Current China about 2.5 hundred million tons of yield of domestic waste year, surrounding city accumulation heap
Rubbish being deposited up to 7,000,000,000 tons, being taken up an area ten thousand mu about more than 80, the city that 2/3 is there are about in 661 cities is surrounded by rubbish, annual economic damage
Lose up to 30,000,000,000 yuans.
The conventional processing mode of house refuse has landfill, burns and compost, wherein landfill, compost have been absorbed in, occupancy is a large amount of to be used
Ground, product marketing be not smooth, the low predicament of resource level, although and burning the mesh that can reach volume reduction decrement and recycling
, its treatment cannot but break away from the problem of bioxin pollution all the time.Refuse pyrolysis treatment be at present generally acknowledge burnt relative to rubbish
More preferable processing mode is burnt, the minimizing treatment for realizing rubbish can not only be cleaned, environment friendly is strong, and can be worth
Oil higher, gas and solid carbon, avoid the generation of bioxin, while most heavy metal is in pyrolytic process from principle
Lime-ash is incorporated, discharge capacity is reduced.
Plasma gasification technology is that material is heated using plasma flare, and local temperature can be to 5500 DEG C of left sides
The right side, and the temperature of reative cell can be made to maintain more than 1000 DEG C, the materials such as pyrolysis oil, bioxin can be rapidly decomposed, and produce big
Amount CO, H2Deng synthesis gas.With secondary pollution it is small, energy recovery utilization rate is high the features such as.
But there is number of drawbacks in prior art.For example, some rubbish rotary kiln pyrogenation techniques, its tar yield is more,
Easily blocking pipeline, etching apparatus etc., frequent parking maintenance, and rear end needs complicated water-oil separating and purifier, leads
Investment is caused to greatly increase.Some rubbish shaft furnace plasma gasification technologies, are directly gasified with plasma torch to rubbish, at place
During reason large scale rubbish, the power of the technique greatly, consumption rate it is very high, therefore cause operating cost to increase, it is difficult to realize work
Industry application.Also some garbage treating process realize that refuse pyrolysis gasify in a stove, although can generate a large amount of synthesis
Gas, but lime-ash has also been carried out melt process simultaneously, and most of material is inorganic matter in lime-ash, is wasted in gasification
Big energy, the heat utilization efficiency of system is relatively low, and operating cost is higher, therefore does not possess comercial operation value.
It is conceived to the big potential energy source of current one --- hydrogen, because it has energy density high, it burns only produce completely
Unboiled water, so there is no any pollution to environment, and burning does not produce carbon dioxide, this has for solving Global Climate Changes
There is very important meaning, it is considered to be most potential vehicle alternative fuel, hydrogen has extremely to changing future source of energy general layout
Close important meaning.
There is expert to point out, if hydrogen is stored in the in-car fuel as engine using compressed gaseous, its efficiency will compare vapour
Oil is higher by 25%.Than conventional gasoline locomotive, its efficiency increases significantly electric automobile with hydrogen as fuel.With traditional vapour
Oil machine car is compared, and has efficiency higher on power chemical energy is changed into.Produced after fuel combustion in conventional gasoline locomotive
Heat and to air work, promotes piston and crank rotation.And fossil energy that fuel cell car will be then stored in hydrogen is straight
Switch through chemical conversion electric energy, then travelled by electrical motor driven vehicle, this is a kind of more direct electrochemical process, thus than tradition
Diesel locomotive has energy conversion efficiency higher, and accessory substance only has water.Due in the electric automobile with hydrogen as fuel
There is no piston and bent axle, largely simplified the parts of transmission system, thus system capacity loss be reduced to it is minimum.
Although hydrogen has the incomparable advantage of many fossil fuels really.But maximum difficulty is exactly hydrogen at present
Prepare.The minimum method of most main flow, cost is hydrogen making by natural gas reformation at this stage, and the hydrogen in the U.S. 95% is obtained by this method.
Basically, natural gas is necessarily accompanied with the generation of oxycarbide during the course of the reaction as the raw material of hydrogen manufacturing, and this is allowed for
Hydrogen is queried as the slogan of vehicle fuel zero-emission.Although hydrogen only produces water, hydrogen really in use
Preparation but have to face the problem of environmental pollution.
In view of the shortcomings of the prior art, with reference to garbage disposal problem of the present utility model and the system of above-mentioned hydrogen as energy source
Standby problem, how environmentally friendly, saving, energy recycling ground treatment rubbish, as the utility model side to be expanded
To.
