Embodiment 1

[0144] This embodiment provides a biomass slurry preparation method, including the following steps:

[0145] (1) Collect wheat stalks with a moisture content of 10-20wt%, and then use an ultrafine pulverizer to crush them to a particle size of 0.2-1 microns;

[0146] (2) Compress and shape the stalks crushed in step (1) with a plodder. The compression pressure is 0.5MPa, the compression temperature is 60°C, and the true density is 0.75kg / m. 3 ;

[0147] (3) The straw after compression molding in step (2) is pulverized again with a jet mill and passed through an 80-mesh sieve to obtain straw powder;

[0148] (4) Mix 100kg of washing oil with 100kg of straw powder from step (3);

[0149] (5) Mix the straw powder mixture obtained in step (4) with 10 kg of water, and use a colloid mill for grinding and pulping. The grinding and pulping time is 8 minutes to obtain a biomass slurry.

[0151] This embodiment provides a biomass slurry preparation method, including the following steps:

[0152] (1) Collect wheat stalks and peanut stalks with a moisture content of 8-20wt%, and then use an ultrafine pulverizer to crush them to a particle size of 0.2-1 microns;

[0153] (2) Compress and shape the stalks after crushing in step (1) with a plodder. The compression pressure is 5MPa, the compression temperature is 30°C, and the true density is 1.5kg / m. 3 ;

[0154] (3) The straw after compression molding in step (2) is pulverized again with a jet mill and passed through a 120-mesh sieve to obtain straw powder;

[0155] (4) Mix 40 kg of anthracene oil with 100 kg of straw powder from step (3);

[0156] (5) Mix the straw powder mixture obtained in step (4) with 3 kg of water, and use a colloid mill for grinding and pulping, and the grinding and pulping time is 20 minutes to obtain a biomass slurry.

Embodiment 3

[0158] This embodiment provides a biomass slurry preparation method, including the following steps:

[0159] (1) Collect corn stalks with a moisture content of 5-20wt%, and then use an ultrafine pulverizer to crush them to a particle size of 0.2-1 microns;

[0160] (2) Compress and shape the stalks crushed in step (1) using a plodder, with a compression pressure of 2.5MPa, a compression temperature of 45°C, and a true density of 1.0kg / m 3 ;

[0161] (3) The straw after compression molding in step (2) is pulverized again with a jet mill and passed through a 100-mesh sieve to obtain straw powder;

[0162] (4) Mix 80kg of waste lubricating oil with 100kg of straw powder from step (3) under a negative pressure of 1 Torr;

[0163] (5) Mix the straw powder mixture obtained in step (4) with 8 kg of water, and use a colloid mill for grinding and pulping, and the grinding and pulping time is 15 minutes to obtain a biomass slurry.

Abstract

The invention belongs to the technical field of recycle of biomass, and particularly relates to a biomass pulp blending method. The provided method mainly comprises the steps of raw material crushing, compressing, secondary crushing, pulp blending and the like, through cooperation of the steps, especially control of the particle size in the two crushing steps and control of the compressing step and a grinding and pulping step, biomass material particles can generate mechanical setting under mechanical action, cellulose and lignin structures are destroyed, and are wound around one another, pores among particles are greatly reduced, materials bond tightly, and air in the massive pores is removed, so that pulping is benefited.

Description

Technical field [0001] The invention belongs to the technical field of biomass reuse, and specifically relates to a biomass slurry preparation method. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, people's demand for energy is increasing, and energy and environmental issues have increasingly become the focus of the international community. At present, coal and oil are still the most important primary energy in the world. With the decrease of primary energy, the quality of the extracted oil and coal declines. How to develop and use renewable energy more scientifically is actively thinking about how to develop and use renewable energy. problem. [0003] Biomass refers to various organisms produced through photosynthesis using the atmosphere, water, land, etc., that is, all living organic substances that can grow are generally called biomass. It includes plants, animals and microorganisms. Representati...
