An integrated downdraft biomass gasification power generation system and method

Abstract

The invention discloses an integrated downdraft biomass gasification power generation system, belongs to the technical field of biomass gasification power generation, and particularly relates to an integrated downdraft biomass gasification power generation system and method. The system comprises a hopper, a reactor, a slag barrel, a cyclone dust remover, an air preheater, an activated carbon adsorber, a gas fan, a torch, an air fan, a gas generator set, a pipeline, a ladder and a base, and is characterized in that the hopper, the air preheater, the cyclone dust remover, the slag barrel and thereactor are coupled into a compact whole, so that the heat efficiency of the whole system is greatly improved. The system is suitable for gasifying straw particles, wood chips, crushed coconut shellsand other carbonaceous biomass materials to generate combustible gas, and the combustible gas is conveyed into a gas engine to be combusted to push the engine to drive a generator to generate electric energy. The system is compact in structure, high in universality, high in energy utilization rate, reliable, convenient to use and easy to operate.

Description

Technical field [0001] The invention belongs to the technical field of biomass gasification and power generation, and specifically is an integrated downdraft biomass gasification and power generation system and method. Background technique [0002] Biomass is the fourth largest energy resource after coal, oil, and natural gas. It is an environmentally friendly renewable resource, accounting for 14% of the world's total energy consumption. In order to fully exploit the material energy and improve my country’s energy structure, the state promulgated and implemented the "Renewable Energy Law" in 2006 to encourage and support the development and utilization of renewable energy, and provide a series of financial discounts for renewable energy development and utilization projects. Tax incentives. [0003] Jiangsu Province is the province with the most biomass power plants in my country. According to the survey, since the State promulgated and implemented the "Renewable Energy Law" in 20...

AI Technical Summary

Problems solved by technology

[0007] 2. The thermal efficiency of the miniaturized biomass gasification power generation system currently on the market is low, and the energy utilization rate is only 20%-30%

Moreover, the system is complex, the floor area is too large, and the investment cost is high

[0008] 3. The effect of the reactor in the existing miniaturized biomass gasification power generation system on the market is poor, and the content of combustible gas tar generated is relatively high

It is necessary to set up filter equipment such as sprinklers and electric coke catchers for purification, and the system is too large and complicated

[0009] 4. The existing miniaturized biomass gasification power generation system on the market will produce a large amount of tar-containing sewage, causing secondary pollution
