Abstract

The invention relates to the field of comprehensive utilization of biomass energy and discloses a biomass briquetting machine and a biomass briquetting process. The biomass briquetting machine includes a loading device, a briquetting device and at least one feeding device. The feeding device is located above the loading device. Through a rotation mode, the loading device having undergone loading is sent to the briquetting device to perform biomass briquetting, wherein the loading device includes a rotating working table arranged on a base and a driving shaft arranged at the rotary center of the rotating working table to be used for driving the rotating working table to rotate, and the driving shaft and a supporting column of the briquetting device are coaxially arranged. A rotating feedingmode is adopted, intermittent feeding and continuous discharging of the biomass briquette can be achieved, and the large-scale production strength is high; the biomass briquetting machine is simple in structure, a briquetting process is simplified, the biomass briquette is high in strength and easy to transport and store.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of biomass energy, in particular to a biomass briquetting machine and a biomass briquetting process. Background technique [0002] Biomass is recognized as one of the most potential non-traditional fossil resources in the world, and it is the fourth largest energy after coal, oil, and natural gas. 14% of the world's energy demand comes from biomass energy, and the proportion in developing countries It is as high as 35%. Biomass energy has become a major development and utilization direction of my country's energy sustainable development because of its renewable, resource-rich and ecologically friendly characteristics. [0003] Among the types of biomass energy in my country, agricultural biomass resources and forestry biomass resources are the most abundant. Among them, agricultural biomass resources include a large amount of straw left on the farmland after harvesting crops, such as corn...
