Biomass gasification power generation apparatus

Abstract

The invention discloses a biomass gasification power generation apparatus, which comprises a screw feeder, a biomass gasification furnace, a cyclone dust removing device, a filter, a condenser, a hydrocyclone separator, a balance tank and a gas storage tank, wherein the screw feeder, the biomass gasification furnace, the cyclone dust removing device, the filter, the condenser, the hydrocyclone separator, the balance tank and the gas storage tank are sequentially connected, the gas storage tank is connected to a gas-fired boiler or a gas-fired generator set, or is directly connected to a gas supply user, an automatic residue discharge system is arranged below the biomass gasification furnace, a dry ash collection device is arranged below the cyclone dust removing device, a buffer membrane sheet is arranged inside the balance tank, a gas cavity is arranged above the buffer membrane sheet, a liquid cavity is arranged below the buffer membrane sheet, and the liquid inlet position of the liquid cavity is provided with a liquid pressure adjustment device. According to the present invention, various components are sequentially connected, the structure is simple and reasonable, and the balance tank is additionally arranged in front of the gas storage tank to balance the gas pressure in the gas storage tank, such that the gas input and output is ensured.

Description

technical field [0001] The present invention relates to the technical field of biomass power generation, in particular to a biomass gasification power generation device. Background technique [0002] Biomass energy is an ideal renewable energy source, which has a wide range of sources, and a large amount of industrial, agricultural and forest wastes are produced every year. Even if not used for energy production, the disposal of these wastes is a headache. When biomass is used as fuel, the net emission of carbon dioxide to the atmosphere is close to zero because the amount of carbon dioxide required for biomass growth is equivalent to the amount of carbon dioxide emitted when it is burned. Moreover, the sulfur content in biomass is extremely low, basically no sulfide emissions. Therefore, the use of biomass as an alternative energy source is of great benefit to improving the environment, reducing the carbon dioxide content in the atmosphere and reducing the "greenhouse eff...
