Embodiment 1

[0017] Corn stalks are used as biomass materials, and the ratio of raw materials according to the mass fraction is high-carbon black shale: corn stalk = 1:1. The preparation method is: separately crush high-carbon black shale and straw, and The black shale is ground to 100 mesh, and the corn stalks are crushed until the particle size of the powder is less than 5mm; then the crushed raw materials are screened by a sieving machine to extract larger pieces and sundries; the screened raw materials are Drying, the working temperature of the high-carbon black shale raw material dryer is 80°C, and the operating temperature of the corn straw dryer is 80°C; mix the high-carbon black shale and corn straw evenly according to the raw material ratio; The preparation machinery carries out pressurization, densification, and molding; finally, the shaped product is sent to the cooling equipment for cooling to obtain the finished pellet fuel.

Embodiment 2

[0019] The mixture of branches, bark and sawdust is used as biomass material, and the ratio of raw materials according to the mass fraction is high-carbon black shale: the mixture of branches, bark and sawdust=1:1.5. The preparation method is: the high-carbon black shale and the mixture of branches, bark and sawdust are crushed separately, and the high-carbon black shale is ground to 90 meshes, and at the same time, the mixture of branches, bark and sawdust is crushed until the particle size of the powder is less than 5mm; Screening to extract larger pieces and sundries; drying the screened raw materials, the working temperature of the high-carbon black shale raw material dryer is 80°C, and the working temperature of the dryer for the mixture of branches, bark and sawdust is 75°C; according to the ratio of raw materials, the mixture of high-carbon black shale and tree bark and sawdust is evenly mixed; then the particle preparation machine is used to pressurize, densify, and for...

Embodiment 3

[0021] Animal manure (cow manure, horse manure) is used as biomass material, and the raw material ratio according to the mass fraction is high carbonaceous black shale: animal manure=1:2, the preparation method is: high carbonaceous black shale and animal manure Grinding the high-carbon black shale to 105 mesh, and crushing the animal feces to a size less than 4mm; then screening the crushed raw materials with a sieving machine to extract larger pieces and sundries; The screened raw materials are dried. The working temperature of the high-carbon black shale raw material dryer is 75°C, and the operating temperature of the animal manure dryer is 85°C; the high-carbon black shale and animal manure are evenly Mixing; then pressurize, densify, and form using a particle preparation machine; finally, send the formed product to a cooling device for cooling to obtain the finished product of particle fuel.

Abstract

The invention discloses a method for preparing an organic pellet fuel by a high-carbon quality black shale mixing biomass material, the method takes high-carbon quality black shale and biologic material as raw materials, ratio of high-carbon quality black shale to biologic material is 1: 1-1: 3 according to mass fraction, the biomass material is a biomass combustible matter mixed by one more than two above components. The raw materials are performed with steps of crushing, screening, drying, mixing, pressurization, densification, moulding and cooling to obtain the organic pellet fuel. The method has the advantages of low cost and low energy consumption; the obtained organic pellet fuel can replace part of traditional fuel; source of high-carbon quality black shale and the biologic material is abundant, production technology is simple, the product has high environment and economic benefit, and the method has important meaning for resource utilization and ecological environment protection of high-carbon quality black shale and the agricultural biologic material.

Description

technical field [0001] The invention relates to a method for preparing organic particle fuels, in particular to a method for preparing organic particle fuels from high-carbon black shale mixed biomass materials. Background technique [0002] As the world's non-renewable energy sources are gradually exhausted, people begin to look for new alternatives, and obtaining fuels such as shale gas from shale has become the latest trend in the world's energy industry. Such as OSAT Co., Ltd. application, the publication number is CN101506331A in the patent literature discloses the name is released from shale and similar material to produce the method for liquid shale fuel, this method is by using vortex motion, wave motion, sound Methods of releasing organic matter from shale oil and similar solid matter by treating shale oil powder in a liquid medium with flow turbulence, or a combination thereof. [0003] As far as China is concerned, the development and utilization of shale energy ...
