Abstract
The invention provides a kind of sludge synthetic fuel and manufacture method thereof, the dirty mud as a raw material that it processes industrial wastewater with sewage treatment plant, city domestic sewage produces, wherein mud and quality of pc ratio is for 2:1 19:1.Mud and coal dust, being delivered to pelletizer with conveying equipments such as conveyer belts or forcing press carries out fuel forming after mix homogeneously according to above-mentioned weight percent in the mixing plants such as blender, the fuel after molding is incendivity after drying in the shade at lucifuge 35 days.Easy dosing of the present invention, combustion conditions and environmental-protecting performance are excellent, have saved coal resources, turn waste into wealth, and greatly reduce Treatment of Sludge cost.
Description
Technical field
The present invention relates to a kind of sludge synthetic fuel and manufacture method thereof, be specifically related to a kind of with mud as primary raw material
Fuel and manufacture method thereof.
Background technology
According to statistics, the annual production of current wastewater treatment in China factory mud reaches tens million of ton, is subject to processing the system of the factors such as cost
About, its main processing mode is that concentration is piled up and fills, and takies substantial amounts of soil and causes environmental pollution.
Along with the development of urbanization, recycling sludge utilizes the attention day by day obtaining people, Chinese patent literature
CN101191089A discloses a kind of sludge coal fuel combination and using method, the wherein ratio by mass percentage of mud and coal
Ratio is: mud accounts for the 50-65% of fuel combination composition, and coal accounts for the 35-50% of fuel combination composition, and above-mentioned fuel combination is using
Time, described fuel combination and bunker coal are respectively fed to boiler, and described fuel combination accounts for the 20-30% of boiler oil total amount.
In the above-described techniques, in described fuel combination, mass fraction shared by mud is not more than 65%, still needs to consume substantial amounts of coal
Charcoal resource；And actual enter stove fuel in, described fuel combination accounts for the 20-30% of total fuel quantity, mud ratio in total fuel
Less than 20%, further increase the consumption of coal resources；On the other hand, mud itself has certain caking property, but above-mentioned
In technology, owing to mud mass fraction in described fuel is not more than 65%, in the case of being added without other binding agent, no
Be enough to make described fuel molding bonded.
Summary of the invention
The technical problem to be solved is to overcome prior art defect, it is provided that a kind of mud utilization rate is high, easily
The sludge synthetic fuel of molding.In order to solve above-mentioned technical problem, the sludge synthetic fuel that the present invention provides, by mud and coal dust
Composition.In described sludge synthetic fuel, mud and quality of pc are than for 2:1-19:1.
Further, the mass ratio of described mud and coal dust is 2:1.
Further, described mud is 3:1 with the mass ratio of coal dust.
Further, described mud is 4:1 with the mass ratio of coal dust.
Further, described coal dust is bituminous coal, anthracite, brown coal or semicoke.
Further, the diameter of described pulverized coal particle is not more than 20mm.
Further, the diameter of described pulverized coal particle is not more than 10mm.
Further, the diameter of described pulverized coal particle is not more than 5mm.
Further, the moisture content of described mud is 10%-95%.
Present invention also offers a kind of described sludge synthetic fuel method of manufacture, comprise the following steps:
A. by mud and coal dust according to corresponding percentage weight mix homogeneously in blender, sludge synthetic fuel is formed；
B. with conveyer belt sludge synthetic fuel is delivered to pelletizer or forcing press is extruded；
C. the sludge synthetic fuel after molding is dried in the shade 3-5 days at lucifuge.
The beneficial effects of the present invention is: (1) mud utilization rate is high: in described sludge synthetic fuel, sludge quality accounting is big
In 66%, in the case of common people think few at coal content and do not have combustion adjuvant, its combustibility is low, but through inventor
Test of many times proves, this sludge synthetic fuel achieves more preferable effect in combustion, and mud utilization rate is high, saves coal
Resource；(2) need not additionally add binding agent: when the mass ratio of mud Yu coal dust is not less than 2:1, contained by mud itself
Caking property can make fuel molding bonded, it is not necessary to adds additional adhesives；(3) sludge synthetic fuel manufacturing process is simple: mud
Itself there is the highest moisture content, easy-formation, when the mass ratio of mud Yu coal dust is not less than 2:1, pelletizing, briquetting etc. can be used
Multiple moulding process makes described sludge synthetic fuel；(4) have good burning performance: mud volatile matter content is high, and during burning, flame is long,
Speed of getting angry is fast；In coal dust, fixed carbon content is high, and burning time is long, flameholding, obtained by the two mixes in the proper ratio
Sludge synthetic fuel, there is speed of getting angry simultaneously fast, the feature such as flameholding；(5) after burning totally, lime-ash is easily pulverized: due to
Not adding the incombustibility binding agents such as clay, described sludge synthetic fuel is after burning totally, and lime-ash is easily pulverized, it is simple to ashman
Make.
Detailed description of the invention
Embodiment one: the mud (moisture content is about 80%) that sewage treatment plant produces and bituminous coal powder are (under the sieve of 5mm mesh sieve
Thing) according to mass ratio 2:1 mix after, use pelletizer to above-mentioned sludge synthetic fuel pelletizing, a diameter of 20-of gained fuel sphere
50mm, after the sludge synthetic fuel after molding dries in the shade 3-5 days at lucifuge, can enter stove and directly burn.
Embodiment two: unlike embodiment one, described mud is 3:1 with the mass ratio of bituminous coal powder.
Embodiment three: unlike embodiment one, described coal dust is anchracite duff.
Embodiment four: mud and coal dust after mix homogeneously, are carried with belt feeder in blender according to the weight ratio of 4:1
To pelletizer, generating 20-50mm fuel sphere, the fuel sphere after molding is incendivity after drying in the shade at lucifuge 3-5 days.
Boiled 2kg water, required time and quality such as following table:
* in table, data are the numerical value that identical burner records under identical combustion method.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, can also make some improvement under the premise without departing from the principles of the invention, these improvement also should be regarded as the present invention's
Protection domain.
