Embodiment 1

[0044] Example 1: With reference to the accompanying drawings, which reflects a specific structure of the present invention, the preparation system of the compressed biomass fuel from pig manure consists of an upper silo 1, an auxiliary material addition silo 2, and its lowering auger and conveyor belt 3. Bacteria sprayer 4, mixer 6, screw extrusion molding machine 7 (such as 140 coal stick machine), block cutter and control box system 8 constitute a continuous production line, and the loading bin 1 is connected by a conveyor belt 3. The feed port 5 of the mixer 6, the conveyor belt 2 between the loading bin 1 and the mixer 6 is connected to the auxiliary material adding bin 2 through the feed auger. The feed port 5 of the mixer 6 is equipped with a bacterial seed liquid sprayer 4 and a mixer 6 The discharge port is connected to the feed port of the screw extrusion molding machine 7, and the discharge port of the screw extrusion molding machine 7 is provided with a block cutter ...

Embodiment 2

[0059] Embodiment 2: The difference from embodiment 1 is:

[0060] ① In the preparation stage, take the dried pig manure that has been fermented in the organic fertilizer fermentation bed of the pig farm, with a moisture content of 21%;

[0061] The proportion is: 78 parts of pig manure residue, 15 parts of coal powder, 1.5 parts of sodium carboxymethyl starch, 2 parts of potassium chlorate, 2 parts of decoking agent, 0.5 parts of anti-smoke agent, 4 parts of industrial salt, pig manure fermentation biological bacteria Species (aqueous) 1 part.

[0062] The moisture content of the pretreated mixture is 20%.

[0063] ②The moisture content of the molded body is 20%.

[0064] ③The moisture content of the finished biomass fuel block is 14%. The total sharing time is 1 day.

[0065] The biomass fuel block produced in this embodiment is a hexagonal hollow column with a diameter of 38 mm, a hollow diameter of 12 mm, and a length of 5 cm. The density is 1290kg / m 3 . No smell. It burns fully...

Embodiment 3

[0066] Embodiment 3: The difference from embodiment 1 is:

[0067] ①Dry manure removal method in the preparation stage collects fresh pig manure residue in the pig farm with a moisture content of 65%;

[0068] The proportion is: 75 parts of pig manure residue, 13 parts of coal powder, 1 part of sodium carboxymethyl starch, 3 parts of potassium chlorate, 2 parts of decoking agent, 1 part of anti-smoke agent, 6 parts of industrial salt, pig manure fermentation biological bacteria Species 1 copy.

[0069] The moisture content of the pretreated mixture is 58%.

[0070] ②The moisture content of the molded body is 58%.

[0071] ③The room temperature in the insulation room is 28℃. The maximum temperature of the fuel block reached 70°C after being placed in the fuel block for 34 hours. The moisture content of the finished biomass fuel block is 16%. The total sharing time is 4 days.

[0072] The biomass fuel block produced in this embodiment is a hexagonal hollow cylinder with a diameter of 3...

Abstract

The invention discloses a method for preparing biomass molding fuel by pressing pig manure. 70-80 parts of pig manure slag, 10-15 parts of pulverized coal, 1-3 parts of sodium carboxymethyl starch, 2-3 parts of potassium chlorate, 2-3 parts of a decoking agent, 0.5-1 part of an antismoke agent, 3-6 parts of industrial salt and 1 part of pig manure fermented biological strain are added to the collected pig manure slag by weight ratio; the mixture is stirred well; the mixture is extruded through a screw extruder and cut, and a molded body is obtained; and then fermentation is performed, and a biomass fuel block is obtained. Sources of raw materials for pig manure are wide, application range is wide, and drying is not required; the molding is good, and density is large; the pig manure can bemolded without high temperature; the biomass molding fuel is environmentally friendly and anti-mildew; and the pig manure can be dried at low cost and without energy consumption.

Description

Technical field [0001] The invention belongs to the treatment and utilization of waste, and relates to the preparation of shaped biomass fuel with pig manure residue as the main raw material. Background technique [0002] Statistics show that the total annual production of livestock and poultry manure in China has reached nearly 4 billion tons, and the chemical oxygen demand of livestock and poultry farms has reached 12.68 million tons, accounting for 96% of agricultural emissions. It is an important source of agricultural pollution. the reason. There are three common models of livestock manure treatment: biogas industry, organic fertilizer industry and combination of planting and breeding. During the promotion of anaerobic fermentation biogas power generation technology, there are high equipment costs, inadequate technical management, slow biogas production process, secondary pollution of biogas liquor, poor gas production efficiency in some biogas digesters, and large seasonal...
