Biomass high temperature pyrolysis and gasification power generation system

Abstract

The invention discloses a biomass high-temperature thermal-decomposition vaporazation generating system which comprises a biomass material bin, a screwed feeder, a biomass whirlwind high-temperature thermal-decomposition gasification furnace, a biomass exhaust pipe, a biomass gas surplus heat utilization steam-generating unit, a biomass gas surplus heat utilization air heater, a biomass gas dust catcher, a water-ring vacuum pump, a biomass gas storage tank, an internal combustion engine, a generator, a high-speed gas fuel combustor, an initialization-phase fuel gas tank, a Roots blower, a water-feeding pump and a clinker pond. When the biomass high-temperature thermal-decomposition vaporazation generating system operates, air and biomass gas heated by the surplus heat of high-temperature biomass gas combust in the high-speed gas fuel combustor to generate high-temperature hypoxia smoke gas which is sprayed into the biomass whirlwind high-temperature thermal-decomposition gasification furnace to be mixed with biomass materials inside the biomass whirlwind high-temperature thermal-decomposition gasification furnace to generate thermal decomposition and vaporization and generate biomass gas with the temperature more than 1600 DEG C and low tar content, and then the biomass high-temperature thermal-decomposition vaporazation generating system generates electricity by utilizing the generator which takes the internal combustion engine as power. The biomass high-temperature thermal-decomposition vaporazation generating system is stable and reliable and has high heat efficiency.

Description

technical field [0001] The invention relates to a power generation system utilizing biomass energy, in particular to a biomass high-temperature pyrolysis gasification power generation system. Background technique [0002] Plants convert solar energy into chemical energy through chlorophyll, and the energy stored in biomass is called biomass energy. Therefore, biomass energy is a renewable energy source. At present, biomass as primary energy usually refers to agricultural and forestry wastes, such as sawdust, bark, rice husk, straw, peanut shells and bagasse. In terms of its energy equivalent, at present, biomass energy ranks fourth after coal, oil, and natural gas. [0003] There are many forms of utilization of biomass energy. Biomass gasification technology converts solid biomass into clean gaseous fuel through thermochemical reactions. Alleviating the growing greenhouse effect is of great significance. [0004] However, the existing biomass gasification processes all u...
