Embodiment 1

[0016] The method for making granular fuel from water hyacinth comprises the following steps:

[0017] (1) After mechanized harvesting of fresh water hyacinth, carry out twice extrusion dehydration until the moisture content of water hyacinth is 70%, and then place it outdoors to dry naturally for 2 weeks, so that the moisture content of water hyacinth is 25%, and set aside;

[0018] (2) The water hyacinth dried naturally in the step (1) is pulverized into water hyacinth particles with a hammer mill with a mesh diameter of 4 mm, and the water hyacinth particles are placed in a constant temperature drying oven at 105 ° C for 8 hours after drying , then evenly spray moisture with a watering can to adjust the water content of the water hyacinth particles to make it a value of 14%;

[0019] (3) Put the water hyacinth granules after adjusting the water content in step (2) into a bio-particle fuel molding device with a temperature of 105°C and a pressure of 7KN for hot-press molding...

Embodiment 2

[0021] The method for making granular fuel from water hyacinth comprises the following steps:

[0022] (1) After mechanized harvesting of fresh water hyacinth, carry out extrusion dehydration twice until the moisture content of water hyacinth is 65%, and then place it outdoors to dry naturally for 1 week, so that the moisture content of water hyacinth is 20%, and set aside;

[0023] (2) The water hyacinth dried naturally in step (1) is crushed into water hyacinth particles with a hammer mill with a mesh diameter of 3 mm, and the water hyacinth particles are placed in a constant temperature drying oven at 100 ° C for 8 hours after drying , then evenly spray the water with a watering can to adjust the water content of the water hyacinth particles to make it a value of 12%;

[0024] (3) The water hyacinth particles after adjusting the water content in step (2) are placed in a bio-particle fuel molding device with a temperature of 100°C and a pressure of 6KN for hot-press molding,...

Embodiment 3

[0026] The method for making granular fuel from water hyacinth comprises the following steps:

[0027] (1) After mechanized harvesting of fresh water hyacinth, carry out two extrusion dehydration until the water content of water hyacinth is 60%, and then place it in the outdoors to dry naturally for 1 week, so that the water content of water hyacinth is 15%, and set aside;

[0028] (2) The water hyacinth dried naturally in step (1) is pulverized into water hyacinth particles with a hammer mill with a mesh diameter of 2 mm, and the water hyacinth particles are placed in a constant temperature drying oven with a temperature of 95 ° C for 8 hours. , then evenly spray moisture with a watering can to adjust the moisture content of the water hyacinth particles to make it 10%;

[0029] (3) The water hyacinth particles after adjusting the water content in step (2) are placed in a bio-particle fuel molding device with a temperature of 95°C and a pressure of 5KN for hot-press molding, a...

Abstract

The invention provides a method for preparing granular fuel by utilizing water hyacinth. The method comprises a set of scientific reasonable steps of mechanically harvesting, naturally airing, crushing into grains, regulating water content, heating, pressurizing and forming. The preparation method is simple, the operation is easy and the granular fuel is prepared under excellent technical conditions; the grain density and the radial compressive resistance of the granular fuel respectively reach up to 1362.21kg/m3 and 1.44KN; the preparation for high-quality granular fuel not only effectively utilizes the water hyacinth resource and reduces the water hyacinth pollution, but also provides a high-quality clean energy, effectively reduces the combustion of non-renewable fuels, such as coal and oil, and achieves the purpose of 'energy conservation and emission reduction'.

Description

technical field [0001] The invention relates to a solid fuel, in particular to a method for making granular fuel by using water hyacinth. Background technique [0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), which is mainly different from fossil fuels. In the current national policy and environmental protection standards, direct combustion of biomass is a highly polluting fuel, which is only used in large stoves in rural areas and is not allowed to be used in cities. The application of biomass fuel is actually mainly biomass briquette fuel, which uses agricultural and forestry waste as raw materials, and through crushing, mixing, extrusion, drying and other processes, it is made into various shapes (such as lumps, granules, etc.), which can be A new type of clean fuel for direct combustion. [0003] Water hyacinth was introduced into China as feed ...
