Abstract

The invention discloses a method and device using biomass boiler smoke to dry biomass raw material. The method comprises the following steps of guiding the biomass raw material to a belt conveyor in a drying chamber, carrying out dynamic conveying, guiding the biomass boiler smoke after being subjected to the dust removal treatment into the biomass raw material to carry out contact heat exchanging, and then removing part of moisture from the biomass raw material; carrying out dust removal treatment on the smoke after being subjected to the heat exchange, directly using the dried biomass raw material as the fuel of a biomass boiler, or storing the dried biomass material for standby. The device mainly consists of a smoke circulation system and the belt conveyor, wherein the smoke circulation system consists of a dust remover, the drying chamber, a booster fan, a draught fan and the like, and the belt conveyor is arranged in the drying chamber and is used for conveying the biomass raw material. The method and the device have the advantages that the structure is simple, the technology is economic, the drying effect is good, the size of the biomass boiler system can be effectively reduced, and the heat efficiency of the biomass boiler system is greatly improved.

Description

technical field [0001] The invention relates to boiler waste heat utilization and energy saving and emission reduction technologies, in particular to a method and a device for drying biomass raw materials by using biomass boiler flue gas. Background technique [0002] As the reserves of traditional fossil energy such as coal, oil, and natural gas decrease day by day, and the environmental pollution caused by the use of fossil energy directly threatens the survival and development of human beings, it has become the government's priority to attach importance to and develop renewable and environmentally friendly energy. Same target. Biomass is an organic substance produced by plants through photosynthesis. It is widely distributed, has a large amount of availability, is cleaner than fossil energy, and has the characteristics of zero carbon dioxide emissions. It is an important renewable energy source. Biomass raw materials generally contain a lot of water. If they are not drie...
