Abstract
The present invention discloses a straw shaped fuel and a preparation method thereof. The straw shaped fuel is characterized in that the straw shaped fuel is extruded after straw powder and coal slack powder are mixed. In the preparation method, various straws are naturally aired to be delivered into a conventional miller to be pressed into straw coarse powder which is less than 15 meshes; the straw coarse powder are delivered into a fine pulverizer to be processed into straw fine powder which is more than 35 meshes; 95 to 98% of the straw fine powder and 2 to 5% of the coal slack powder are mixed to be delivered into a forming machine and be extruded into shapes.
Description
Technical field
The present invention relates to a kind of New-type fuel and preparation method thereof.
Background technology
For a long time, in vast rural area, people make fuel with various crop stalks always.Along with improving constantly of people's living standard, the enhancing of the variation of fuel band and people's environmental consciousness, coal, coal gas, liquefied gas etc. substantially in the city and the suburb popularize, so the utilization ratio of straw is also more and more lower.Because straw does not well utilize method, for solving the occupation of land problem, the peasant has to carry out burning disposal in the field, and this has caused huge inconvenience for traffic and environment, and this is the shortcoming that exists in the prior art.
Summary of the invention
The straw shaped fuel that the purpose of this invention is to provide a kind of environmental protection and energy saving can effectively overcome the low shortcoming of straw utilization ratio in the prior art.
Another object of the present invention provides the making method of this straw shaped fuel.
Fuel of the present invention is by straw powder and the moulding of colliery powder extrusion.
Described straw powder is the above straw fine powders of 35 orders.
The blending ratio of described straw fine powder and colliery powder is (weight ratio):
Straw fine powder 95%～98% colliery powder 2%～5%
The optimum weight proportioning of making fuel of the present invention is (weight ratio):
Straw fine powder 96～97% colliery powders 2～3% that 35 orders are above
Fuel preparation method of the present invention is:
1, various crop stalks is dried naturally;
2,, be processed into the following straw meal of 15 orders by common pulverizer;
3,, be processed into the above straw fine powder of 35 orders by fine pulverizer;
4, the straw fine powder is mixed according to the above ratio with colliery powder, send into shaper, machine-shaping gets final product.
Because component of the present invention comprises straw fine powder and colliery powder, therefore easily after machine-shaping and the moulding volume little, effectively having overcome existing farm crop, to deposit floor space big, and the shortcoming of contaminate environment; Simultaneously, moulding afterfire value height, and solved the lack of fuel problem in vast rural area, help energy-conservation.
The coal quality industrial ultimate analysis report that following table is done for fuel of the present invention
As can be seen from the above table, the content of sulphur is extremely low after the fuel combustion of the present invention, therefore has the characteristics of environmental protection.
Embodiment
After getting crop stalk and drying, send into common pulverizing and be machined to the following meal of 15 orders, meal is sent into the pulverizing fine powder that is machined to more than 35 orders, fine powder and colliery powder are pressed following weight ratio: fine powder 97%, colliery powder 3% mixes, and sends into shaper machine-shaping then and gets final product.Fine pulverizer among the embodiment can adopt LB13 tobacco pulverizer, and the shaper in the course of processing can adopt HB-CX type tobacco molding device.
Claims (3)
1, a kind of straw shaped fuel is characterized in that: it is to be crushed to according to the following weight ratio by straw fine powder more than 35 orders and colliery powder:
Straw fine powder 95%～98%; Colliery powder 2%～5%.
2, straw shaped fuel according to claim 1 is characterized in that: the weight ratio of straw fine powder and colliery powder is: straw fine powder 96～97%; Colliery powder 3～4%.
3, the preparation method of the straw shaped fuel of claim 1 is characterized in that: send into common pulverizing after various straws are dried naturally and be machined to less than 15 purpose straw meal; Again this straw meal is sent into the pulverizing above straw fine powder of 35 orders that is machined to; Being 95～98% straw fine powder with weight ratio mixes with 2～5% colliery powder, sends into the shaper extrusion molding and gets final product.
