Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0023] figure 1 It is a schematic structural diagram of a system for efficiently preparing biomass pellet fuel using straw and paper mill black liquor as raw materials provided by the present invention. The system includes a flat-plate solar collector 1, a straw-black liquor mixing dryer 2, and a pulverizer 3 , greenhouse-heat-collecting solar drying room 4, biomass molding machine 5, wherein the heat collected by the flat-plate solar collector 1 is used to increase the temperature of the air S1 entering the collector, so that the air S1 reaches the time when the biomass is dried In addition, the heated air S1 is divided into two parts, and one part uses the blower to carry the wheat straw into the straw-black liquor mixi...

Abstract

The invention relates to a system for preparing a biomass pellet fuel by taking straws and black liquor of paper mills as raw materials. The system comprises a flat plate type solar thermal collector, a straw and black liquor mixing dryer, a pulverizer, a greenhouse-heat-collecting type solar energy drying chamber and a biomass forming machine. Solar energy is adopted as the source of drying energy to play the roles of cleaning, drying and energy saving; the straws and the black liquor of the paper mills are adopted as the source of biomass forming raw materials to increase the characteristic of the biomass pellet fuel; moreover, the toughness of the straws is reduced after the straws are mixed with the black liquor and preliminarily dried and the biomass raw materials are pulverized on the basis, so that the biomass raw material pulverizing energy can be reduced and the energy loss is reduced. The system disclosed by the invention has the advantages of solving the problem of pulverizing the biomass straw raw materials, increasing the forming characteristic of the biomass forming pellet fuel and reducing the drying time and energy of the biomass raw materials.

Description

technical field [0001] The invention relates to the technical field of biomass pellet fuel molding, in particular to a system for efficiently preparing biomass pellet fuel by using straw and paper mill black liquor as raw materials. Background technique [0002] At present, human beings are in an energy society, which makes human beings use energy resources to meet their own needs and develop social processes, but also bear the dual pressures on the environment and energy brought about by energy consumption and utilization: on the one hand, the use of mineral energy increasingly exhausted. According to current consumption calculations, global oil resources will be exhausted in the next 40 to 70 years, and the current international oil market price is about 6 times that of more than 20 years ago, which means that the reserves of fossil energy will be reduced. less and less, the market price will gradually increase, indirectly affecting the development of the economy and soci...
