Embodiment 1

[0032] A method for producing biomass fuel by utilizing the waste residue of preparing gallic acid, wherein, the waste residue of preparing gallic acid includes wood fiber, activated carbon and water; the mass percentage of wood fiber in the waste residue is 25% to 30%; the mass percentage of waste activated carbon in the waste residue 30-40%; the mass percentage of water in the slag is 30-45%.

[0033] Such as figure 1 As shown, the method specifically includes the following steps:

[0034] (1) Add 1500L tap water in the enamel reactor of 3000L, turn on the stirring paddle, and add gallic acid waste residue 1000Kg (the water content is 45% in the assay) into the reactor; be heated to 85°C; The fraction is 30% sodium hydroxide solution, adjust the pH to pH 6, and keep warm for 10 minutes;

[0035] (2) Utilize plate and frame filter press to separate slag material and water, the pressure of plate and frame filter press is controlled at 0.2Mpa, obtain slag material (moisture c...

Embodiment 2

[0039] A kind of method utilizing the waste residue of preparing gallic acid to produce biomass fuel, described method specifically comprises the following steps:

[0040] (1) Add 1000L tap water in a 3000L enamel reaction kettle, turn on the stirring paddle, and add 1000Kg of gallic acid waste slag (moisture content is 45% as tested) into the reaction kettle with tara powder as raw material; heat to 95°C; Add a sodium hydroxide solution with a mass fraction of 50%, adjust the pH to 6.5, and keep warm for 30 minutes;

[0041](2) Utilize plate and frame filter press to separate slag material and water, the pressure of plate and frame filter press is controlled at 0.3Mpa, obtain slag material (assay to get water content to be 45%);

[0042] (3) the slag material that step (2) is obtained is dried through a vacuum drier, and the vacuum drier is controlled to be dried for 5 hours under the condition of -0.08~-0.09Mpa; %);

[0043] (4) Press the dried slag, and press it into gran...

Embodiment 3

[0045] A kind of method utilizing the waste residue of preparing gallic acid to produce biomass fuel, described method specifically comprises the following steps:

[0046] (1) Add 1750L tap water in the enamel reaction kettle of 3000L, open the stirring paddle, will be the waste residue 1000Kg (the moisture content is 45% that is tested to get water content) to add in the reaction kettle with Galla gall or tara powder as raw material production gallic acid; Heat to 90 ℃; add a sodium hydroxide solution with a mass fraction of 40%, adjust the pH to a pH of 7, and keep warm for 20 minutes;

[0047] (2) Using a plate and frame filter press to separate the slag from water, controlling the pressure of the plate and frame filter at 0.2 to 0.3Mpa to obtain the slag;

[0048] (3) The slag material that step (2) is obtained is dried through a vacuum drier, and the vacuum drier is controlled to dry for 4 hours under the condition of -0.08~-0.09Mpa; %);

[0049] (4) Press the dried sla...

Abstract

The invention mainly belongs to the technical field of environment-friendly new energy and particularly relates to a gallic acid production waste biomass fuel and a preparation method thereof. The method comprises taking gallic acid production waste as the raw material, adjusting the PH value of the waste, heating the PH-adjusted waste, and then performing filter pressing, drying and granulation on the waste to obtain the gallic acid production waste biomass fuel. By taking the gallic acid production waste as the raw material, the preparation method is simple in process and low in treatment cost, achieves recycling of the waste, saves forestry resources, reduces environmental pollution and provides a granulated biomass fuel environment-friendly new energy.

Description

technical field [0001] The invention mainly belongs to the technical field of environmental protection and new energy, and in particular relates to the production of raw material fuel and a preparation method using waste residues prepared from gallic acid. Background technique [0002] The production of gallic acid is made from forest plant gallnut or tara powder, etc., through alkaline hydrolysis, neutralization, coarse crystallization, decolorization and refining, etc. It is a fine chemical product with a wide range of uses, mainly used in organic Synthesis, medicine, dyestuff, feed, food, light industry and electronics industry. Among them, gallnut is a traditional forest product in my country. Gallnut is suitable for growing in warm and humid mountains and hills. The main production areas in my country are concentrated in six provinces including Guizhou, Sichuan, Hubei, Hunan, Shaanxi, and Yunnan. The output of gallnut in these provinces is about Accounting for more than...
