Embodiment 1

[0045] Embodiment 1 of the present invention utilizes pig manure, biomass powder (bamboo sawdust), high charcoal ash, and slaked lime to produce biofuel particles with a size of 8-10 mm. It includes the following steps:

[0046] (1) Mixing raw materials in proportion, the proportion makes the final product include 70% pig manure, 25% bamboo sawdust, 1% slaked lime, 4% high carbon ash extracted from fly ash by dry weight; wherein , the peculiar smell of pig manure can be removed during the stirring process; the pig manure used has a water content of 45%, bamboo wood chips have a water content of 45%, slaked lime has a water content of 20%, and high charcoal ash has a water content of 35%;

[0047] (2) Utilize the drying machine to dry the raw materials mixed and stirred in step (1) to about 14% water content;

[0048] (3) adding a binding agent such as modified starch to the dried raw material in step (2), and stirring;

[0049] (4) Put the raw materials stirred in step (3) i...

Embodiment 2

[0070] Embodiment 2 of the present invention is similar to embodiment 1, and it utilizes pig manure to manufacture the biofuel particle that size is 5-7 millimeter, and carries out granulation with granulator, and it comprises the following steps:

[0071] (1) Raw materials are mixed in such a proportion that the final product comprises 68% pig manure, 18% bamboo sawdust, 2% slaked lime, and 12% high carbon ash extracted from fly ash by dry weight; wherein , in the process of stirring, the peculiar smell of pig manure can be removed; the used pig manure contains 52% water, bamboo sawdust contains 48% water, slaked lime contains 20% water, and high carbon ash extracted from fly ash contains 38% water;

[0072] (2) Utilize the vacuum belt dehydrator to dehydrate the mixed and stirred raw materials in step (1) to about 18% water content;

[0073] (3) adding binder such as cornstarch to the dehydrated raw material in step (2), and stirring;

[0074] (4) drying the raw materials s...

Abstract

The invention discloses a process for preparing granular biomass fuel by using pig manure and a prepared product. The process disclosed by the invention comprises the following steps of: (1) mixing raw materials such as the pig manure, biomass powder crumb and high charcoal ash in proportion; and according to the proportion, the final product comprises 60-90% of pig manure, 10-30% of biomass powder crumb and 1-30% of high charcoal ash by dry weight; (2) dehydrating the mixed raw material obtained in the step (1); and (3) pelletizing the raw material dehydrated in the step (2). According to the invention, the biomass powder crumb and the high charcoal ash are added into the pig manure, thus peculiar smell of manure is removed and ignition point of the obtained fuel is reduced.

Description

technical field [0001] The invention relates to a process for preparing granular biomass fuel from pig manure and the resulting product; more specifically, the present invention relates to a process for preparing granular biomass fuel from pig manure by using high carbon ash as a deodorant and the resulting product Background technique [0002] my country is a big pig raising country. According to statistics, the daily excrement volume of pig farming industry alone is 2.91 million tons, and the annual excrement volume is 1.062 billion tons. At present, the pig manure discharged from a large number of professional pig farms and farm households in China is directly used as fertilizer for crops, which not only emits a large amount of odor, but also pollutes the environment. [0003] Chinese patent application 200810045547.8 discloses a method for processing and utilizing pig manure, which includes: 1. Regulating moisture: fresh pig manure and dry pig manure are stirred and mix...
