Abstract
Excrement of a bull kept for covering burns the gasification craft, including the following step: (1) The river cow dung dehydrates drily; (2) Cow dung and straw after the river dehydrates drily, the rice husk is mixed according to the following ratio by weight; Cow dung: 60-90%, the straw: 10-20, rice husk: 10-20% (3) sends the mixture into the combustion furnace to burn; (4) Cool burning the flammable gas produced; (5) It is after it cool gas last dust removal, get rid of impurity of; (6) Get rid of the tar, namely make the gas. This invention is used ro dealing with the cow dung, can not merely carry on effective treatment of the cow dung, and utilize fully energy, cow dung each do cow dung can produce the flammable gas of 1000cu m after the famous craft of this law is dealt with, the offal is few, and solid thing, small, it is a kind of environmental protection typ that deals with the craft. The flammable gas produced is accumulated and can be burnt directly, can be used for generating electricity.
Description
Technical field
The present invention relates to a kind of utilization of cow dung and the preparation technology of inflammable gas, specifying is that a kind of cow dung is burned gas-made technology.
Background technology
The recycling of cow dung mainly contains following several mode both at home and abroad at present.
1, compost
Cow dung is a kind of resource of preciousness as a kind of animality organic fertilizer.The ox food consumption is big, the excrement of discharging every day, urine also many than other domestic animals.An adult ox, whenever defecation amount round the clock reach 42.9kg (amplitude is 28.4～48.1kg), whenever round the clock voided volume be 10.2kg (amplitude is 6.5～14.1kg), adds pad grass, but the about 20t of production in every year high-quality organic fertilizer.It is ammonium sulfate 261kg that a head of cattle year defecation amount is amounted to chemical fertilizer quantity, calcium superphosphate 78.2kg, vitriolate of tartar 86.88kg.Farm crop are used the effect that cow dung urine also has the structure of improving the soil and preserves moisture, improve agroecological environment.If be processed into biological organic fertilizer, its economic benefit will be to sell 18 times of cow dung.
Weak point is the densification of cow dung quality, and composition is similar to pig manure, water content height (about 50%) in the cow dung, and air permeability is poor, decomposes slowly, and leavening temperature is low, and fertilizer efficiency is slow, claims that cow dung is " cold manure " so practise.
2, act as a fuel
The many areas of China are some pastoral areas especially, and most of local herdsman are still following ancient Energy utilization patterns---burn cow dung.Cow dung is taken as a kind of fuel, is used as life fuel, warms oneself, cooks.
The subject matter that cow dung is used as the fuel combustion existence is to produce a large amount of obnoxious flavoures, contaminate environment, and capacity usage ratio is low, and the biomass energy waste is serious.
3, producing methane
The calorific value of cow dung is up to 3907J/m
3, the therefore existing practice that cow dung oven dry back is produced biogas by fermentation.The mode of utilizing of this cow dung not only can not brought harm to environment, and waste material is fully used, and is a kind of environment-friendly type treatment process.But this facture exists energy utilization rate low, and the waste quantity of generation is big, also need carry out the problem of secondary treatment.
Summary of the invention
The present invention will solve is exactly that the energy utilization rate that present cow dung does not obtain fully effectively utilizing and existing cow dung gas-made technology exists is low, and the waste quantity of generation is big, also need carry out the problem of secondary treatment.
The present invention adopts following technical scheme to utilize cow dung to produce inflammable gas:
1, cow dung is dehydrated;
2, the cow dung after will dehydrating is mixed by following weight ratio with straw, rice husk:
Cow dung: 60～90%, straw: 10～20%, rice husk: 10～20%
3, mixture being sent into roasting kiln burns;
4, will burn the inflammable gas that produces cools off;
5, cooled gas is carried out dedusting, remove impurity;
6, remove tar, promptly make desired gas.
The present invention is used to handle cow dung, not only cow dung effectively can be handled, and the energy is fully used, and cow dung can produce 1000M through dried cow dung per ton after the art breading of the present invention
3Inflammable gas, waste is few, and is solids, and volume is little, is a kind of environment-friendly type treatment process.The inflammable gas that produces can directly burn, and also can be used for generating.
After testing, adopt the composition of the inflammable gas that prepared of the present invention comes out as follows:
