Abstract

The invention discloses straw sludge fuel which is prepared by 50 percent of straw powder, 20 percent of sewage disposal settling sludge, 25 percent of coke blacking, and 5 percent of yellow mud or lime. The straw sludge fuel replaces coal and releases the coal short supply state; the combustion heating value reaches 4000-4800 kilocalories; the straw sludge fuel can be applied to the industrial boiler production and the family life stove, has no black smoke when in combustion and is rather well received by a user.

Description

A kind of stalk sludge fuel

Technical field

The present invention relates to straw utilization and disposal of three wastes.

Background technology

Current the discarded of agricultural crop straw become social effects of pollution, all kinds of sewage disposal glaurs are also more and more many.One goes out the surplus ton of mud 1000-2000 little county town year, one go out mud local level city year can tons up to ten thousand or tens thousand of ton, go out mud big and medium-sized cities year and reach tens of and even up to a million tons.These precipitating sludges contain flammable organism and objectionable impurities, especially contain germ, virus and become disease breeding ground and contagium, and people's life and health in serious harm; What have contains soda acid or heavy metal element, and the biological procreation of harm and growing up though be the waste of sewage disposal, has caused secondary pollution to environment, is called second source of pollution by people.

Therefore, need to be resolved hurrily to agricultural crop straw and all kinds of combustible waste material utilization and to the harmless processing of sewage disposal precipitating sludge.

Summary of the invention

The objective of the invention is handling problem, propose a kind of fuel that utilizes stalk and mud to produce at agricultural crop straw and sewage disposal glaur.

Stalk sludge fuel of the present invention is processed by straw powder 50%, sewage disposal glaur 20%, coke powder 25%, tamanori 5% (yellow mud or lime), and above-mentioned percentage ratio is weight percentage.

Add man-hour, straw powder pulverized to fine powder (being called for short " grass meal "), mix, add coke powder and tamanori then, stir and use high-pressure forming machine compression moulding with the sewage disposal glaur, drying or dry after promptly become fuel.

Positively effect of the present invention is:

1, solves the problem of environmental pollution of stalk and precipitating sludge, removed the objectionable impurities of mud after especially burning;

2, can be used as energy new way, replace coal, alleviate coal energy state in short supply, its combustion heating value reaches 4000-4800 kilocalories;

3, strong operability can be founded the factory in combination area of city and country position, draws materials conveniently, saves cost, and is economical and practical, and ton valency cost only accounts for 1/4 of coal price, and selling price can be controlled in about 1/2 of coal price, and is lucrative.For example build a small-sized factory and produce 1000 tons per year, can arrange the laid-off worker or return to one's home village farming worker 8-10 people; Build a medium-sized factory, produce ten thousand tons per year, post 50-80 people can arrange employment or reemploy; Build a large-scale factory and produce person more than 1,000,000 tons per year, then can arrange more personnel's employment.

Fuel of the present invention can be used for industrial boiler production and family life stove and accessory, does not have black smoke during burning, tries to burn rather well received through the user.

Embodiment

Further specify technical scheme of the present invention below in conjunction with concrete working method.

1, it is stand-by combustiblematerialss such as stalk to be ground into the powder shape;

2, the sewage disposal glaur being rejected its hard sundry goods (as stone, iron block etc.) smashs to pieces stand-by;

3, mix by following part by weight, stir; Straw powder 50%, precipitating sludge 20%, coke powder 25%, tamanori 5%;

4, the compound after will stirring drops into tablets press, makes the different particulate state of specification or with high-pressure forming machine compression moulding piece;

5, carry out drying treatment, dry or dry and become finished product, and intensified waterproof measure.

Claims

1, a kind of stalk sludge fuel is characterized in that, it is processed by straw powder 50%, sewage disposal glaur 20%, coke powder 25%, yellow mud or lime 5%, and above-mentioned percentage ratio is weight percentage.
