Embodiment 1

[0011] A method for producing high-density fuel by using cow dung, comprising the following raw material proportions in parts by weight: 120 kg of fermented and mature cow dung, 20 kg of crop straw, and 15 kg of sawdust powder; wherein the crop straw is corn and rice straw After crushing the mixture, the cow dung is piled up and fermented until it is fermented until the color of the cow dung is brownish black, the texture is soft, and there is no odor, which is the fermented cow dung; the fermented cow dung is mixed with crop straw and sawdust powder Stir and mix evenly, press to form, air-dry naturally for 3 to 5 days, and then use a dryer to dry at 100°C until the water content is less than 10%.

[0012] Further, the mature fermented cow dung is prepared by adding 3 kg of quick-rot agent to 1000 kg of fresh cow dung, and after fully stirring, it is made into a pile of 1m high, 2m wide, and 10m long, and the piles are placed at intervals of 3m. A ventilation pipe with holes i...

Embodiment 2

[0014] A method for producing high-density fuel by using cow dung, comprising the following raw material proportions by weight: 150 kg of fermented and mature cow dung, 15 kg of crop straw, and 10 kg of sawdust powder; wherein, the crop straw is selected from corn, rice The mixture of stalks and beans that are crushed separately, and the cow dung is accumulated and fermented until it is fermented until the color of the cow dung is brownish black, soft in texture and odorless, which is fermented mature cow dung; fermented mature cow dung Stir and mix with crop stalks and sawdust powder evenly, press to form, air-dry naturally for 3 to 4 days, and then use a dryer to dry at 100°C until the water content is less than 10%.

[0015] Further, the mature fermented cow dung is prepared by adding 3 kg of quick-rot agent to 1000 kg of fresh cow dung, and after fully stirring, it is made into a pile with a height of 1.5m, a width of 3m, and a length of 15m. A ventilation pipe with holes ...

Embodiment 3

[0017] A method for producing high-density fuel by using cow dung, comprising the following raw material proportions by weight: 130 kg of fermented and mature cow dung, 18 kg of crop straw, and 12 kg of sawdust powder; the crop straw is a mixture of crushed corn stalks , the cow dung is matured by stacking and fermenting until the color of the cow dung is brown-black, soft and odorless, which is the fermented cow dung; the fermented cow dung is mixed with crop straw and sawdust powder evenly, and pressed Shaped, air-dried for 4-5 days, and then dried in a dryer at 100°C until the moisture content is less than 10%.

[0018] Further, the mature fermented cow dung is prepared by adding the quick-rot agent in a ratio of 1000 to 3 by weight, and after being fully stirred, it is made into piles with a height of 1.2m, a width of 2.4m, and a length of 12m. The piles are placed at intervals of 3m. A ventilation pipe, and the pipe wall of the ventilation pipe is provided with holes. Acc...

Abstract

The invention relates to a method for manufacturing high-density fuel from cow dung. The fuel comprises, according to a weight part ratio, 120-140 parts of fermented mature cow dung, 15-20 parts of crops straw, and 10-15 parts of sawdust powder. The method comprises: uniformly stirring and mixing fermented mature cow dung with crops straw and sawdust powder, performing compression moulding, performing natural air-drying for 3-5 days, and performing drying at 100 DEG C through a dryer, till the water content of the obtained product is less than 10%. According to the method, the utilization rate of cow dung resources is improved, pollution to a cattle farm is greatly reduced, and pollution to the environment is limited. The fermented cow dung is developed to be fuel, so that cost of a culture farm is reduced, development of cattle raising industry is promoted, and the problem of fuel shortage is overcome. The method provides a significant way for improving an environment energy utilization ratio. The biomass dung is developed into new energy, and an energy utilization mode is explored.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of waste resources such as excrement from cattle raising and crop stalks, and specifically relates to a method for making high-density fuel by using cow dung. Background technique [0002] With the continuous improvement of people's living standards, the demand for meat continues to increase, especially beef is a food that people all over the world love to eat, and has become one of the most commonly eaten meats for consumers, second only to pork. Beef is rich in It has high protein, amino acid and trace elements, and low fat content, so it tastes delicious and has high nutritional value. It is loved by people and enjoys the reputation of "the favorite of meat". Because beef is rich in protein, its amino acid composition is closer to the needs of the human body than pork, which can improve the body's disease resistance. It is especially suitable for people who grow and develop, p...
