Abstract
The invention discloses a preparation method of a sludge clean fuel. The preparation method disclosed by the invention is characterized by comprising the following steps: roasting sludge at high temperature at first, so that the moisture content is decreased to 5% and below, then, mixing the sludge with acetylene sludge, manganese and iron slag, sphalerite, blast furnace slag, an oxidizing agent and a synergist material, crushing initially, and then, secondarily crushing till the particle size is 100-200 meshes. The sludge clean fuel prepared by adopting the technical scheme can be directly doped with coal to burn; negative effects to a coal-fired furnace can be avoided; the sludge clean fuel can be directly applied to daily industrials and civil direct combustion boilers; practical detection proves that the heat value of the sludge clean fuel is 3500-5000 Kcal/Kg and achieves the medium heat value fuel grade; and, due to the sludge clean fuel, accumulation of sludge and industrial wastes and pollution to the environment are greatly reduced.
Description
Technical field
The present invention relates to clean energy technology field, be specifically related to a kind of preparation method of mud clean fuel.
Background technology
Along with national economy and social development, daily life intensive degree is more and more higher, and the organic waste of generation gets more and more, and causes great impact to the living environment of the mankind.Municipal sludge is as the byproduct of sewerage system, it is the sedimentable matter that sewage work produces in water treatment procedure, both containing a large amount of microorganism, organic matter and nutritive substance, it has large, unstable, easily corruption, high stench the feature of capacity, also contain the heavy metal, pathogenic agent microorganism etc. that exceed standard in a large number in mud simultaneously, if do not dealt carefully with, the hazardous and noxious substances such as wherein comprised heavy metal, pathogenic agent microorganism, once penetrate into soil, can cause the irreversible poisoning of crop pollution soil; Once go deep into underground water, valuable water resources will be polluted, potential safety hazard is caused to the safe drinking water of resident.In the treating processes of municipal sludge, it is high that current Problems existing concentrates on dehydration cost, and refuse landfill is unwilling to process.Be rich in organic mud in a large number to expose in atmosphere, be very easy to smelly, and then can cause mosquito fly, agricultural chemicals deinsectization is adding two degree of possibilities polluted again virtually.And getting more and more along with sewage work's foundation, the output of mud, also in increase, allows municipal sludge process be absorbed in a kind of dilemma.
In addition on the one hand, along with the fast development of China's industry, various industrial waste radix increases severely day by day.Especially the industrial discharge amount such as metallurgy, large-scale mining is huge.The industrial waste substantial amounts of China, of a great variety, complicated component, process is difficulty quite.At present in China, a few industrial waste is only had to be utilized, such as: part flyash is for the production of cement, production building brick.Major part industrial waste still saves as master, such as blast furnace slag, ferromanganese ore slag etc. with passiveness heap.A large amount of passivenesses of industrial waste are stored up and are not only taken a large amount of soil, cause the waste of manpower and materials, and many industrial residues contain material soluble in water, by leaching contaminated soil and water body.The industrial waste of powdery, flies upward with the wind, atmosphere pollution, and what have goes back emitting offensive odor and poison gas.Some refuses even silt river course up, pollute water system, affect biological growth, and harm resident is healthy.
For current this situation, need to develop a kind of sewage sludge harmlessness, energy, mass-producing method of comprehensive utilization, not only can solve serious pollution problem, the clean fuel that directly can utilize, meet combustion row standard can also be obtained simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of mud clean fuel, not only can solve serious pollution problem, can also obtain the clean fuel that directly can utilize, meet combustion row standard simultaneously.
In order to solve the problem, the present invention is by the following technical solutions:
A kind of mud clean fuel, is characterized in that: each constituent mass number of described mud clean fuel is:
Carbide slag 10 ~ 15 parts;
Ferromanganese ore slag 5 ~ 15 parts;
25 ~ 30 parts, zink sulphide stone;
Blast furnace slag 1 ~ 5 part;
30 ~ 40 parts, mud;
1 ~ 5 part, oxygenant;
Synergistic agent 0.5 ~ 3 part.
Described oxygenant is one or more the mixture in calcium peroxide, Potcrate, sodium chlorate, potassium permanganate.
Described synergistic agent is one or more the mixture in ferrocene, metallic aluminium powder, metal iron powder, metal magnesium powder.
A kind of preparation method of mud clean fuel, it is characterized in that: preparation process is, first high bake is carried out to mud, make it moisture and be reduced to less than 5%, then carry out mixing pulverizing for the first time with carbide slag, ferromanganese ore slag, zink sulphide stone, blast furnace slag, oxygenant, synergistic agent material, then carry out separating twice to grain diameter and be of a size of 100 ~ 200 orders.
Implement technical scheme of the present invention, there is following beneficial effect: adopt the mud clean fuel prepared by this technical scheme can directly and coal adulterate and burn, can not cause negative impact to coal-fired furnace kiln, this mud clean fuel can directly apply to daily industry, civilian direct-combustion boiler.Detect through reality and prove, the calorific value of described mud clean fuel is 3500 ~ 5000Kcal/Kg, reaches medium Btu fuel rank.The pollution that the heap sum that this mud clean fuel greatly reduces municipal sludge and trade waste causes environment.
