Experimental result
The water retting characteristic
(1) rate of expansion is illustrated among Fig. 1.Compare at garbage fuel that is mixed with brown coal and the sample of not sneaking into brown coal as seen from Figure 1, it is very strong to water resisting dipping power.
(2) stripping composition
Table 5
*-big ▲-few zero-nothing
By using brown coal to a certain degree, the stripping composition has just disappeared as can be seen from Table 5.
In addition, because the effect of the sulphur in the brown coal, the generation of hydrogenchloride in the time of can reducing burning improves efficiency of combustion.
The deodorization characteristic
(1) for the deodorization characteristic (function test) of rubbish
Pass through as can be seen to use a certain amount of above brown coal by table 6 and table 7, can obtain the good smelly property that disappears.
Moreover, in Fig. 2, represented to use the fine pore distribution curve of brown coal.
Reference example 2
Moist in order to measure detesting of comminuted coal different water-contents, below the particle diameter 2.5mm, sample is put into the beaker that water is housed, and stir several times, then, measure the sample weight (as shown in Figure 3) that is positioned at water surface top.
Here, detesting moist (%) calculates { water surface upper sample (g)/sample full weight amount (g) } * 100 in such a way.
As can be seen from Figure 3 water-content before about 20%, can obtain good detest moist.
Can find out significantly from above, according to the present invention, can utilize little brown coal and the reluctant rubbish of purposes in the world, perhaps apply flexibly the characteristic that coal had, by with the hybrid shaping of rubbish, can remove stink, obtain being easy to the carrying storage, and can reduce the generation of hydrogenchloride during burning, increase heat recovery efficiency, can obtain roughly the necessarily fuel of the generating of combustion conditions usefulness or other usefulness, and then can solve the landfill problem, therefore can bring into play very big effect for refuse treatment.Can bring into play following effect.
1. because the adsorptivity of brown coal or coal can make rubbish eliminate stink.
2. because the water-absorbent of coal can reduce the drying process that rubbish is pulverized product.
3. because detesting of brown coal or coal is moist, thus can long storage, and can be used as and specially use with fuel.
4. owing in brown coal or coal, sneak into rubbish, make mixture be difficult to disintegration, dust do not take place, in operation to healthy and beneficial.
5. because the brown coal that appropriate amount is sneaked into or the thermal value of coal even the thermal value of rubbish changes, also can obtain roughly certain combustion conditions, obtain uniform state of combustion, so can carry out stable generating etc.
Fig. 1 is the test card of Stinkless garbage fuel opposing water retting power of the present invention.
The fine pore distribution curve of the brown coal that Fig. 2 is to use.
Fig. 3 is the water-content of comminuted coal and detests moist graph of a relation.
