Embodiment 1

[0019] Such as figure 1 Shown, the manufacture method of mulberry twig briquette fuel is that the raw material mulberry twig is poured into the pulverizer to pulverize, and then the weight of 95 parts of mulberry branch powder, 2 parts of combustion aid coal combustion fly ash, 2 parts of kaolin and 1 part of lime powder The parts are weighed, put into the mixer to stir and mix evenly, and then sent to the pressure roller ring model briquette forming machine through the conveyor, the control pressure is 100Mpa, the temperature is 230°C, and the intermittent extrusion is made into a prism, and the mold is demoulded. After natural cooling, the final packaging is to obtain the mulberry branch shaped fuel product. The technical indicators of this product are: the density is 1.1g / cubic centimeter, the calorific value is 4650kcal / kg, the ash content is 1.38%, and the water content is 12%.

Embodiment 2

[0021] Such as figure 1 Shown, the manufacture method of mulberry twig briquette fuel is that raw material mulberry twig is poured into pulverizer and pulverized, and then the weight of 97 parts of pulverized mulberry branch powder, 1 part of combustion aid pulverized coal, 1 part of kaolin and 1 part of lime powder The parts are weighed, put into the mixer, stirred and mixed evenly, and then sent to the pressure roller ring model briquetting machine through the conveyor to control the pressure at 200Mpa and the temperature at 150°C for continuous extrusion into a circular shape with a hole in the middle The cylinder is cooled naturally after being demoulded, and finally packaged to obtain the mulberry branch shaped fuel product. The technical indicators of this product are: the density is 1.2g / cubic centimeter, the calorific value is 4960kcal / kg, the ash content is 1.45%, and the water content is 11%.

Embodiment 3

[0023] Such as figure 1 Shown, the manufacture method of mulberry twig briquette fuel is that the raw material mulberry twig is poured into the pulverizer to pulverize, and then the weight of 95 parts of mulberry branch powder, 2 parts of combustion aid coal combustion fly ash, 2 parts of kaolin and 1 part of lime powder The parts are weighed, put into the mixer and mixed evenly, and then sent to the hydraulically driven piston-type molding machine through the conveyor, the control pressure is 100Mpa, the temperature is 210°C to perform intermittent extrusion into prisms, and naturally cool after demoulding , and finally packaged to obtain the mulberry branch shaped fuel product. The technical indicators of this product are: the density is 1.0g / cubic centimeter, the calorific value is 4713kcal / kg, the ash content is 1.28%, and the water content is 11.5%.

Abstract

The invention discloses a manufacturing method of a mulberry twig briquetting fuel, which comprises the following steps: pulverizing 95-97 parts of mulberry twig and 3-5 parts of combustion improver, mixing, and briquetting under the pressure of 50-250 MPa at the temperature of 70-250 DEG C. The mulberry twig briquetting fuel belongs to renewable high-quality biomass energy sources converted by discarded materials, can replace mineral energy fuels, such as coals and the like, and can be widely used for the fields of agricultural production and living. The mulberry twig briquetting fuel can beused as a domestic fuel for living, and can also be used as an energy source for heat supply and power generation. The ash obtained after combusting the mulberry twig briquetting fuel can also be used as a fertilizer, thereby increasing the incomes of peasants, improving the living environment and solving the problem of environmental pollution caused by silkworm excrement. The invention also develops a new energy source, and has obvious effects of comprehensive benefits, including social benefit, economic benefit, energy benefit, environment benefit and the like. Thus, the invention can be used as an important means for settling waste of discarded materials and environmental pollution in the current sericulture industry.

Description

technical field [0001] The invention belongs to the technical field of utilization of silkworm industry waste and environmental protection, and relates to a method for manufacturing mulberry branch briquette fuel. Background technique [0002] Mulberry branch, also known as mulberry stem, mulberry branch, etc., is one of the by-products of silkworm industry. Mulberry trees are cut once a year in winter and summer, and each hectare of 15 mu mulberry field can produce 38 tons of mulberry branches. Guangxi is the largest production base of my country's sericulture industry. The area of ​​mulberry fields and the output of silkworm cocoons have ranked first in the country for five consecutive years. , the advantageous livelihood industry of strengthening the county economy, involves the livelihood of nearly 880,000 farmers and 3.5 million people. Guangxi's existing adult mulberry field area has exceeded 134,000 hectares, with an annual output of more than 5 million tons of mulber...
