Abstract

The invention provides a biomass comprehensive utilization system and a biomass comprehensive utilization method. The system comprises forming equipment, a conveying system, a biomass boiler, a biomass gasification / carbonization furnace, an SCR denitration device, a bag type dust removal device, a desulfurization device and a wet electric dust removal device, wherein the forming equipment is usedfor compression forming of a biomass raw material, the conveying system is used for conveying the compressed and formed biomass into the biomass gasification / carbonization furnace, the biomass boileris provided with a biomass inlet, a fuel gas inlet, a combustor and a flue channel, the flue channel is divided into a first flue channel section and a second flue channel section by a partition plate, a flue channel gas outlet is formed in the side wall of the tail of the first flue channel section, and the flue channel gas outlet sequentially passes through a high-temperature cyclone separator and an SCR denitration device and is connected to a flue channel gas inlet formed in the side wall of the top of the second flue channel section through pipelines.

Description

Technical field [0001] The invention relates to a biomass comprehensive utilization system and method, and belongs to the technical field of biomass utilization. Background technique [0002] Depletion of fossil fuels, carbon dioxide emissions that may cause global warming, and air pollutants such as NO X And SO X The emergence of some environmental challenges are urgent to be solved. [0003] Biomass, including vegetation, human and animal manure, is a renewable and sustainable energy source, and its rational use can effectively alleviate the aforementioned environmental challenges. Compared with fossil fuels, biomass energy has significant environmental benefits, including CO 2 And other air pollutants. One promising application of biomass is the production of syngas through a gasification process. Syngas can be used as fuel and raw chemicals in the combustion process. However, low energy density, seasonal characteristics, difficulty in collecting, transporting, and maintainin...
