Brief introduction
Based on the combination of biomass characteristics and rapid pyrolysis equipment, the fluidized bed semi-coke gasification and biomass hydropyrolysis technology are coupled, and the circulating fluidized bed staged pyrolysis gasification technology is the core, and the raw materials are processed into hydrogen
Biomass hierarchical pyrolysis gasification process
(1)Raw material pretreatment
The biomass raw material is crushed by the pulverizer and then enters the drying and lifting device, and the biomass particles are dried and upgraded using low-temperature flue gas at about 120°C to remove water.
(2) Pyrolysis and gasification reaction
The dried biomass particles enter the intermediate silo, and are fed into the lower part of the gasification furnace through a screw feeder, and are quickly mixed with the circulating heat carrier and high-temperature gas to perform high-temperature hydrogen pyrolysis reaction to generate high-calorific value gas. The tar is completely cracked in this process, mainly producing small molecular gas.The high-temperature materials are circulated back to the bottom of the furnace and undergo combustion and gasification reactions with air and low-pressure steam at a high temperature of about 900°C to generate CO, H2, CO2, etc.
(3) Gas purification
The gas at the outlet of the gasifier is returned to the bottom of the fluidized bed as the gasification raw material by the semi-coke and the carrier through the first and second horizontal gas-solid high-efficiency separation of the gas and solid; the fine powder separated by the three-stage separator is sent as silicon potash fertilizer . After dust removal, the gas enters the waste heat boiler to recover heat, and then is purified by a two-stage moving bed, cooled and sent to the power generation system.
(4) Gas power generation
The purified gas directly enters the internal combustion engine for power generation; it can also be compressed and boosted into the gas turbine for power generation, and the steam recovered from the waste heat enters the steam turbine for power generation, improving the overall power generation efficiency.
Features of Biomass pyrolysis gasification power generation technology
1. The pyrolysis and gasification process system and equipment have strong adaptability, wide applicability, and flexible operation. The daily biomass processing capacity can be combined into various scales from 100 tons to more than 1,000 tons, and various comprehensive biomass treatment plants can be built.
2. The gasification intensity is large, the single furnace processing capacity is large, the fixed investment is greatly reduced; the operation is simple, the startup and shutdown are convenient, and the continuous production.
3. Large-scale closed production lines will not affect the surrounding environment. Realize professional and fine production, all adopt computer DCS automatic control, and have no adverse effects on the surrounding environment.
4.The generated combustible gas has high methane content and high calorific value, which is suitable for making gas.
Product Advantage
