Embodiment l

[0016] The wet sawdust is crushed and screened to make the particle size ≤1.5mm; then the selected sawdust is sent to the drum drying room for heating and drying at a temperature of 70°C; after that, degassing and impurity removal After processing, it is sent to the ring die compression equipment for extrusion molding to make light yellow energy particles with a diameter of 6mm and a length of 6-30mm; then sent to the cooling equipment for cooling, screening, packaging and storage, and the product molding rate reaches 98%. Moisture content is not more than 8%.

Embodiment 2

[0018] The wet rice hulls are crushed and screened to make the particle size ≤7mm; then the selected sawdust is sent to the drum drying room for heating and drying at a temperature of 30°C; after that, degassing and impurity removal are carried out Finally, it is sent to the ring die compression equipment for extrusion molding, and made into light yellow energy particles with a diameter of 6mm and a length of 6-30mm; then sent to the cooling equipment for cooling, screening, packaging and storage, the product molding rate reaches 98%, and the water content The rate is not more than 8%.

Embodiment 3

[0020] Mix the crushed sawdust and rice husk in a ratio of 1:1, and send them to the mixer to stir evenly; then send the uniformly mixed raw materials into the drum drying room for heating and drying at a temperature of 50°C; after that, in After degassing and impurity removal, it is sent to the ring die compression equipment for extrusion molding to make light yellow energy particles with a diameter of 6mm and a length of 6-30mm; then sent to the cooling equipment for cooling, screening, packaging and storage, the product The molding rate is 98%, and the moisture content is not more than 8%.

Abstract

The invention discloses a process for preparing biomass energy particles, wherein the biomass energy particles are prepared from sawdust or rice hulls or a mixture of the sawdust and the rice hulls through machining and pressing. The process comprises the following steps of: crushing the sawdust to be less than or equal to 1.5mm and the rice hulls to be less than or equal to 7mm; conveying the sawdust, or the rice hulls or the mixture of the sawdust and the rice hulls into a drying room for heating and drying, wherein the drying temperature is 20-80 DEG C; and conveying the dried raw material into ring die pressing equipment, carrying out cold molding to prepare the biomass energy particles. The process disclosed by the invention has the advantages of reasonable raw material formula, favorable technical performance and low energy consumption and production cost. Compared with the traditional biomass particle fuel, the biomass energy particles prepared by utilizing the process disclosed by the invention have the advantage that: energy consumption and cost can be reduced by 20 percent. The biomass particles prepared by utilizing the process disclosed by the invention do not add any chemical preparation, and have no any pollution to environment in production and practical processes.

Description

technical field [0001] The invention relates to a process for preparing biomass energy granules, in particular to a biomass energy granule which can use recycled sawdust, rice husks or their mixtures as raw materials. Background technique [0002] At present, the three main energy sources used worldwide are oil, natural gas and coal, all of which are non-renewable energy sources, and are facing the dilemma of depletion with the increase of demand and exploitation. The shortage of conventional energy supply has seriously affected the rapid development of the social economy, and the large-scale concentrated use of fossil energy has released a large amount of carbon, sulfur, nitrogen oxides and other substances, resulting in aggravated environmental pollution and global warming. serious harm to the environment. To this end, my country promulgated the "Renewable Energy Law" in January 2006 to encourage the development of renewable energy industries and technology development....
