Description
Technical field
The invention belongs to biomass fuel technical field, be specifically related to a kind of biomass fuel piece production method, and realize the crowded stranding machine of stalk, biomass fuel die forming machine alive and the biomass fuel production system of the method.
Background technology
Because life in the countryside level improves, peasant reduces the dependence of crops stalks fuel in recent years, causes and has every year a large amount of crop stalks to retain, and has brought no small trouble to Straw treatment and the spring ploughing in the coming year. Due to reasons such as the thin and farming of soil horizon of ploughing have high input, also process that to implement difficulty large in field for the deep ploughing of straw, abandon stacking and take again a large amount of cultivated land resources, therefore peasant is many or adopt directly burning for the processing mode of straw. But not only there is the risk of initiation fire in crop straw burning, also can cause air pollution, this had both endangered environment, wasted again resource. In recent years, government just forbids that crop straw burning problem put into effect a lot of ways and suggestion, but does not all receive significant effect, the reason of searching to the bottom, be straw as a kind of biomass energy not by effective exploitation and utilization, also fail to embody its due society and commercial value.
Meanwhile developing rapidly of China's economy consumed a large amount of energy, and this not only causes the minimizing year by year of fossil energy, along with the problem of environmental pollution that increases of energy resource consumption is also on the rise. Therefore want to accelerate the process of China's new road toward industrialization and Realization a Fairly Well-off Society in a all-around Way under the prerequisite of protection of the environment, just must utilize regenerative resource to replace and supplementary traditional energy. Crop stalk is exactly good biomass energy, after the solid fuel that straw is squeezed into quality densification, regular shape through former, has that volume is little, density is large, accumulating is convenient; Grade is higher, fuel characteristic is good; Green non-pollution, clean hygiene, the advantage such as easy to use, can the alternative ore energy be widely used in that people produce and the every field of life. Thereby alleviate the depletion rate of the resources such as coal, reduce the discharge capacity of dusty gas, improve the energy resource structure of China, for ensureing national energy security, improve the ecological environment, promote energy-saving and emission-reduction, realize low-carbon economy, being all significant for new countryside construction provides clean energy resource.
Biomass fuel piece curing molding technology is mainly divided into hot compression forming technique, cold compression forming technique and carbonization forming technique. Hot compression forming technique refers to; Biomass material is heated to, between 170 DEG C-220 DEG C, by applying certain pressure, biomass material is compressed to the shaped fuel with certain density. Its moulding mechanism is by the mode of heating, makes the lignin in biomass material softening. Lignin is insoluble to any organic solvent at normal temperatures, but when temperature is during at 200-300 DEG C, the variation that lignin can Yin Wendu and softening. In the softening process of lignin by it is applied to certain pressure, can make the materials such as cellulose in itself and biomass material closely bond and the distortion of generator tool and plastic flow, on perpendicular to direction of maximal stress, particle is mainly with intermeshing, and on perpendicular to minimum stress direction, particle is the mode combination to be mutually close to mainly, gets final product curing molding after cooling.
Current biomass molding fuel production equipment both domestic and external mainly contains roller single lead screw ex truding briquetting machine, screw rod continuously extruding and molding machine, Mechanical Driven impact briquetting machine and hydraulic-driven impact briquetting machine.
