Problems solved by technology

[0004] In recent years, domestic and foreign patents have also been reported on the technology of preparing fuel from pig manure. However, in the prior art, the hot pressing and product drying in the production process require expensive equipment investment and more energy consumption, which increases the Production cost; secondly, the existing preparation method has extremely high requirements on the moisture content of pig manure, and the moisture content is required to be controlled within a very narrow range. If the moisture content is too low or too high, it will lead to unsuccessful molding or granulation of solid fuel. However, in It is difficult to control the moisture content of pig manure during the production process

Embodiment 1

[0044] Embodiment 1: Referring to the accompanying drawings, reflecting a specific structure of the present invention, the preparation system of the biomass briquette fuel pressed by pig manure is composed of an upper feeding bin 1, an auxiliary material adding bin 2 and its unloading auger, and a conveyor belt 3. Strain sprayer 4, mixer 6, screw extruder 7 (such as 140-type coal rod machine), cutting machine and control box system 8 form a continuous production line, and the feeding bin 1 is connected by a conveyor belt 3 The feeding port 5 of the mixer 6, the conveyor belt 2 between the feeding bin 1 and the mixer 6 is connected to the auxiliary material adding bin 2 through the feeding auger, the feeding port 5 of the blender 6 is provided with a strain sprayer 4, and the blender 6 The discharge port of the screw extruder 7 is connected to the feed port of the screw extruder 7, and the discharge port of the screw extruder 7 is provided with a cutting machine (not shown in th...

Embodiment 2

[0059] Embodiment 2: the difference with embodiment 1 is:

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

[0061] The ratio 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 smoke suppressant, 4 parts of industrial salt, pig manure fermentation biological bacteria Seed (aqua) 1 part.

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

[0063] ② Moisture content of molded body is 20%.

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

[0065] The biomass fuel blocks produced in this embodiment are hexagonal hollow columns 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. The combustion is compl...

Embodiment 3

[0066] Embodiment 3: the difference with embodiment 1 is:

[0067] ① In the preparation stage, dry manure method is used to collect fresh pig manure residue in the pig farm house, with a moisture content of 65%;

[0068] The ratio 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 smoke suppressant, 6 parts of industrial salt, and pig manure fermenting biological bacteria Plant 1 part.

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

[0070] ②Moisture content of molded body is 58%.

[0071] ③The room temperature in the insulation room is 28°C. After the fuel block was put in for 34 hours, the maximum temperature of the fuel block reached 70°C. The moisture content of the finished biomass fuel block is 16%. The total time spent is 4 days.

[0072] The biomass fuel blocks produced in this embodiment are hexagonal hollow columns with a diamet...

Abstract

The invention discloses a preparation method of biomass briquette fuel pressed from pig manure, adding 70-80 parts of pig manure and slag, 10-15 parts of coal powder and sodium carboxymethyl starch to the collected pig manure and slag according to the weight ratio 1 to 3 parts, 2 to 3 parts of potassium chlorate, 2 to 3 parts of decoking agent, 0.5 to 1 part of smoke suppressant, 3 to 6 parts of industrial salt, 1 part of pig manure fermentation biological strain; stir evenly; through screw extrusion Extruded by a machine, extruded and cut to obtain a molded body; and then fermented to obtain a biomass fuel block. There are many sources of pig manure raw materials, which are widely applicable and do not need to be dried; the shape is good, the density is high, and the pig manure can be formed without high temperature; it is environmentally friendly and mildew-proof; it is low-cost and consumes no energy to dry the manure.

Description

technical field [0001] The invention belongs to the treatment and utilization of waste, and relates to a biomass fuel prepared by taking pig manure slag as a main raw material. Background technique [0002] Statistics show that at present, the total amount of livestock and poultry manure produced in China reaches nearly 4 billion tons every year, and the chemical oxygen demand of livestock and poultry breeding sites reaches 12.68 million tons, accounting for 96% of agricultural source emissions, which is an important source of agricultural source pollution. reason. There are three common modes of livestock and poultry manure treatment: biogas industry, organic fertilizer industry and combination of planting and breeding. In the promotion process of anaerobic fermentation biogas generation technology, there are high equipment costs, poor technical management, slow biogas production process, secondary pollution of biogas slurry, poor gas production efficiency of some biogas d...
