Embodiment 1

[0062] Example 1 of the present invention utilizes pig manure to produce biofuel pellets with a size of 8-10 mm. It includes the following steps:

[0063] (1) Stir after mixing pig manure, powdery activated carbon, and bamboo sawdust according to the dry weight ratio of 8:1:1, and remove the peculiar smell of pig manure during the stirring process;

[0064] (2) Utilize the vacuum belt dehydrator to dehydrate the mixed and stirred raw materials in step (1) to about 25% water content;

[0065] (3) Add binder such as modified starch (corn modified starch) to the dehydrated raw material in step (2), and stir;

[0066] (4) Put the raw materials stirred in step (3) into the shaping and feeding equipment, and after the raw materials are shaped, be sent to a 2000-ton press to be pressed into a plate-shaped semi-finished product;

[0067] (5) Utilize the tunnel dryer to dry the plate-shaped semi-finished product obtained in step (4) to about 5% water content;

[0068] (6) Utilize fi...

Embodiment 2

[0093] Embodiment 2 of the present invention is similar to Embodiment 1, and its difference is:

[0094] (1) The manure used is a mixture of cow manure and horse manure;

[0095] (2) Granulate by flat die or ring die granulator.

Abstract

The invention discloses a process for preparing activated carbon livestock excrement fuel, which comprises the following steps of: (1) mixing and stirring raw materials, wherein on a dry weight basis, the raw materials comprise 60 percent-80 percent of livestock excrement, 10 percent-30 percent of biomass silt-sized grain, and 1 percent-30 percent of activated carbon; (2) dehydrating the raw materials stirred by the step (1); and (3) granulating the raw materials dehydrated by the step (2). The process for preparing the activated carbon livestock excrement fuel has the advantages that: the process is simple, and activated carbon used as a deodorizer can be prepared through flotating or carbonizing pulverized fuel ash.

Description

technical field [0001] The invention relates to the production of fuel by utilizing poultry and livestock manure, and more specifically, the invention relates to a process for preparing active carbon poultry and livestock manure fuel. Background technique [0002] The feces of poultry and livestock cause serious pollution to the environment, which makes farmers very headache. The usual solution to poultry manure is to use it as a field fertilizer. In recent years, the energy use of poultry manure has been proposed. Burning dung for heating has existed since ancient times. The dung fuel does not contain sulfur and will not release gases that cause global warming when burned, which is conducive to protecting the atmospheric environment. [0003] Generally speaking, poultry manure has a high calorific value in a state where the water content is less than 40%. However, in order to achieve this low moisture content state, long-term natural drying or artificial heating and dryi...
