Abstract
The invention discloses a method for preparing biomass fuel through crop straw carbonization, and belongs to the technical field of biomass fuel preparation. The method comprises the following steps:a, placing a carbonization furnace in a vacuum environment, and extracting air in the carbonization furnace to form a vacuum environment therein, wherein a belt transmission structure is arranged inside the carbonization furnace, the belt transmission structure performs transverse transmission, an infrared irradiation structure is arranged on the top of the carbonization furnace, a feed port is formed in the upper end of the carbonization furnace, and a discharge port is formed in the lower end of the carbonization furnace; b, further forming an air outlet in the upper end of the carbonizationfurnace, communicating the air outlet with an air inlet of an induced draft fan through a hose, enabling an air outlet of the induced draft fan to stretch into a heat exchange box, enabling gas extracted by the induced draft fan to exchange heat with crop straw in the heat exchange box, and enabling the crop straw after heat exchange to enter the carbonization furnace through the feed port; c, enabling the gas after completion of the heat exchange to enter a distilling tower, and separating to obtain liquid-phase wood vinegar and gas-phase water vapor. The method has an energy-saving effect.
Description
technical field [0001] The invention relates to the technical field of biomass fuel preparation, in particular to a method for preparing biomass fuel by carbonizing crop straws. Background technique [0002] my country is a country with a large output of straw, and the pollution of crop straw has always been the bottleneck of agricultural development. According to the biomass conversion pathway, current biomass energy utilization technologies include physical conversion, biological conversion and chemical conversion. Physical transformation mainly includes physical compression and briquetting treatment to prepare biomass solid briquettes; biological transformation mainly includes anaerobic digestion to produce biogas and fermentation to produce ethanol; chemical transformation includes liquefaction, gasification, carbonization, etc. [0003] Liquefaction and gasification methods have been studied more in the past few years, and these two methods mainly have the problem that...
