Abstract

The invention discloses a processing device of biomass pellet fuel. The processing device of the biomass pellet fuel comprises a pulverizer, a first cylinder and a second cylinder which are connected sequentially, wherein the pulverizer is connected with the first cylinder through a belt, an induced draft fan is arranged at the feeding end of the first cylinder, magnetic boards which are mounted on a center shaft of the cylinder and parallel to the center shaft are arranged in the first cylinder and are fixed in the cylinder through support columns fixed on the inner wall of the cylinder; a gas channel is formed between the first cylinder and the second cylinder, and an air blower is arranged at a discharge port of the second cylinder; the first cylinder and the second cylinder are both inclined, and the feeding ends are higher than the discharge ends. The invention further discloses a processing method of the biomass pellet fuel. The processing method comprises steps as follows: selection, pulverizing, primary drying and secondary drying. Heat provided by a heat source is sufficiently utilized, so that energy consumption is reduced, and the cost is reduced; the magnetic boards are arranged in the first cylinder and used for adsorbing iron wires and iron nails in saw dust, and the influence of metals on pelleting is eliminated.

Description

Technical field [0001] The invention relates to the field of energy, in particular to a processing device and a method for biomass pellet fuel. Background technique [0002] Biomass refers to various organisms produced through photosynthesis using the atmosphere, water, land, etc., that is, all living organic substances that can grow are generally called biomass. At present, energy crisis and environmental pollution are common problems facing the world. Solving energy shortages and environmental pollution caused by energy development is the key to human sustainable development. Among them, biomass energy is solar energy stored in biomass in the form of chemical energy. Energy form, that is, energy with biomass as a carrier, has the dual characteristics of renewable and low pollution, and is considered an important part of future renewable energy. The efficient development and utilization of biomass energy will play a very positive role in solving energy and ecological environmen...
