Biological-material ball gasifying method and apparatus

Abstract

This invention relates to a biological material gasifying field including: a fan, a flowmeter, a water tank, a loop gas-collecting chamber, a hearth, a purifier, a stove, a heat preservation layer, a loop air-preheating room, a grate, a gasification agent tube and biological balls characterizing in applying vapor and air or air as the gasification agent and applying specially made biological balls of honeycomb balls as the raw material to produce combustible gas, in which, the upper part of the outside of the stove is a water tank made of stainless steel, the fan is connected with a loop air preheating chamber at the bottom of the hearth via the gasification agent tube, the heat preservation layer, the inner container and the hearth are orderly set in the stove, the grate is under the hearth and an ash chamber is under the grate, the loop gas collecting chamber is above the inner container and is connected with a strong fire stove, a gas stove and a heating stove via the gas conduction tube and the purifier, the end of the gas conduction tube is the chimney with a valve on it.

Description

technical field [0001] The invention relates to the field of biomass gasification, in particular to a biomass pellet gasification method and equipment thereof. Background technique [0002] At present, the research and development of biomass energy technology has become one of the world's major hot topics, and has attracted the attention of governments and scientists around the world. Many countries have formulated corresponding development and research plans, such as Japan's Sunshine Project, India's Green Energy Project, the United States' Energy Farm and Brazil's Alcohol Energy Project, among which the development and utilization of biomass energy occupies a considerable proportion. [0003] my country is a large agricultural country with "shortage of resources and large population", and is rich in biomass resources. With the vigorous development of the market economy, energy consumption is increasing day by day. Now my country's national conditions are: on the one hand,...

Problems solved by technology

However, this technology is not yet mature enough. Burn-through phenomenon often occurs during use, the burning time is short, continuous burning is not possible, the gas supply is impure, the combustion is insufficient, the thermal efficiency is low, the cold furnace starts for a long time, the fuel consumption is large, and energy saving Poor effect, serious environmental pollution, especially all small biomass gasification furnaces use granular materials, the gas is difficult to export from the furnace, the content of fly ash is high, the gas guide pipe is easy to be blocked, and the fly ash is recombined If the tar that is difficult to dispose of is mixed together, the pipeline will undoubtedly be blocked, and the dispersal of the farmers’ raw materials for making granules will also increase additional costs, and the furnace will generate a lot of smoke when it is working. Leakage of air will cause both energy loss and operational troubles, which will lead to interruption of cooking and even affect the physical and mental health of cooking staff

Therefore, many gasifiers are in non-working or semi-working state, causing direct economic losses to farmers, so there is still much room for improvement in this field
