Problems solved by technology

In recent years, people have also studied a lot of biomass energy and its high-efficiency compression molding methods. Since the processed materials are high-fiber materials, and the raw materials are loose, with various sizes and materials, it is difficult to compact them into dense particles during particle molding. It needs to contain viscous components, such as Chinese patent: CN201210328869.X, a biomass fuel with good formability, characterized in that the biomass fuel is mixed with wood powder and additives, and the additives have high viscosity and adsorption Strong high-clay, mixed with sawdust and additives in a ratio of 9:1 to make a renewable biomass fuel that does not contain any harmful substances. Although there is no problem of environmental pollution when burned, the above additives need to be soaked, ground, Dehydration, surface activation, crushing and packaging, blending and other processes are made by scientific formula and special processing technology. The type of raw material is single, with the characteristics of complex process and high cost

Embodiment 1

[0022] Embodiment 1: Take the raw material of moisture content 50% as example:

[0023] Use a pulverizer to pulverize the biomass raw materials into granules or powders with a diameter of 3mm, sieve and sieve, and sieve the oversized ones for re-crushing or as fuel to the drying equipment, and then transported to the drying equipment by belts Equipment, using a belt with an effective width of 40mm, a raw material thickness of 3mm, and a speed of 350r / min for the feeding belt; using drying equipment to dry the crushed raw materials, the speed of the drying equipment is 700r / min, and the drying temperature in the cylinder is 320 °C, the cylinder wall temperature is 400 °C, so that the moisture content of the raw material is 12%.

[0024] The dried material enters the stone remover through the traction of the fan to remove impurities such as stones, then enters the cyclone separator, and then is sent to the forming step, and the dust enters the bag filter for unified recycling an...

[0025] Embodiment 2: Take the raw material of moisture content 60% as example:

[0026] Use a pulverizer to pulverize the biomass raw materials into granules or powders with a diameter of 3mm, sieve and sieve, and sieve the oversized ones for re-crushing or as fuel to the drying equipment, and then transported to the drying equipment by belts Equipment, using a belt with an effective width of 40mm, the thickness of the raw material is 2.5mm, and the speed of the feeding belt is 330r / min; the raw material after crushing is dried with a drying equipment, the speed of the drying equipment is 600r / min, and the drying temperature in the cylinder 330°C, cylinder wall temperature 410°C, so that the moisture content of the raw material is 13%.

[0027] The dried material enters the stone remover through the traction of the fan to remove impurities such as stones, then enters the cyclone separator, and then is sent to the forming step, and the dust enters the bag filter for unified rec...

Embodiment 3

[0028] Embodiment 3: Take the raw material of 70% moisture content as example:

[0029] Use a pulverizer to pulverize the biomass raw materials into granules or powders with a diameter of 3mm, sieve and sieve, and sieve the oversized ones for re-crushing or as fuel to the drying equipment, and then transported to the drying equipment by belts Equipment, using a belt with an effective width of 40mm, the thickness of the raw material is 2mm, and the speed of the feeding belt is 300r / min; the raw material after crushing is dried with a drying equipment, the speed of the drying equipment is 500r / min, and the drying temperature in the cylinder is 340 °C, the cylinder wall temperature is 420 °C, and the moisture content of the raw material is 15%.

[0030] The dried material enters the stone remover through the traction of the fan to remove impurities such as stones, then enters the cyclone separator, and then is sent to the forming step, and the dust enters the bag filter for unifi...

Abstract

The present invention discloses a biomass briquette preparation method, which comprises: carrying out crushing and screening on lignin-containing agricultural production and industrial production waste, drying, reducing the water content, carrying out impurity removing and dust removing, carrying out roller pressing molding, and carrying out cooling packaging to obtain the biomass solid fuel. According to the present invention, the raw material variety is more, the production process is simple, any additives are not required, the preparation is completely dependent on the high-pressure extrusion molding of the molding machine, the cost is low, emission of waste residue, waste gas and waste water during the production is not generated so as not to cause the secondary pollution, and the method is suitable for promotion application.

Description

technical field [0001] The invention relates to the field of solid fuel production, in particular to a method for preparing biomass briquette fuel. Background technique [0002] The development of clean energy and global climate change are the focus of common attention of the international community. During the 200 years of industrialization in the world, only developed countries with a population of less than 1 billion have achieved modernization, but global resources and ecology have paid a heavy price for this. In this context, many countries represented by Europe and the United States have increased their attention and investment in the utilization of biomass energy. [0003] In order to promote the development and utilization of biomass through scientific planning, Chinese government departments, scientific research institutes, and international organizations have successively carried out planning and forward-looking research work on the development and utilization of b...
