Household biomass pyrolysis charcoal gas co-combustion method and stove

Abstract

The invention belongs to the technical field of household biomass gasifiers, particularly relates to a household biomass pyrolysis carbon-gas combined combustion method and a cooking range and provides a technical scheme for pyrolyzing two reaction products (gas and carbon residues) and jointly combusting the two reaction products in different time periods and in different places for cooking. The cooking range comprises a rotary drum type pyrolysis reactor, a stator with a hollow cylinder structure and a rotor installed at the center of the stator in a sleeved mode, wherein the stator comprises a housing, a heat preservation layer, an electric heating layer, an electric heating radiation cavity and a converged sunlight irradiation cavity penetrating all layers, wherein the housing, the heat preservation layer, the electric heating layer, the electric heating radiation cavity and the converged sunlight irradiation cavity are sequentially arranged from outside to inside. The rotor comprises an inner housing and an inner housing inner-wall blocking plate, wherein a cap is arranged at one end of the inner housing, a rotary interface is formed in the other end of the inner housing, the heat preservation layer, the housing and a gear are sequentially fixed to the outer sides of two ends of the inner housing exposing out of the stator, and the gear is coupled with a gear on a motor shaft. Tar is not contained in discharged smoke, no tar is left in the cooking range, fire does not break out without ignition, the cooking heat quantity is increased, and the cooking range is simple in use and suitable for household cooking and heating of farmers and herdsmen.

Description

technical field [0001] The invention relates to a biomass cooking method and a stove, belonging to the technical field of household biomass gasifiers, in particular to a household biomass pyrolysis charcoal-gas co-firing method and a stove. Background technique [0002] Faced with the dual pressures of economic growth and environmental protection, human beings must take the road of low-carbon economy. Therefore, renewable energy has been mentioned in an important position. In the vast rural and pastoral areas, there are a large number of biomass resources, including wastes in the agricultural production process (such as corn straw, sorghum straw, wheat straw, rice straw, bean straw and cotton straw and other crop straws), agricultural processing industry wastes (such as wood chips, rice husks) and livestock manure, etc., farmers and herdsmen families rely on these biomass as fuel for cooking and heating. The most primitive and simplest form of utilization is direct combusti...

AI Technical Summary

Problems solved by technology

[0007] The present invention mainly solves the problem of high tar content caused by low gasification temperature in the prior art, and easily blocks the gasification furnace, cooker and pipeline, and provides a household biomass pyrolysis charcoal-gas co-combustion method and a cooker. The method and the stove do not contain tar in the smoke exhaust and no tar remains in the stove, which is beneficial to environmental protection

[0008] Another purpose of the present invention is to solve the problems existing in the prior art such as difficulty in ignition, long ignition time, air pollution and threats to human health caused by excessive discharge of smoke and CO gas pollutants, and to provide a household bio Material pyrolysis charcoal-gas co-combustion method and stove, using the method and stove, no ignition and slag removal, no tar and dense smoke emissions pollute the air and pose a major threat to human health, improving safety

[0009] Another object of the present invention is to solve the problems in the prior art that the gas output and quality are unstable and the gasification process is difficult to control, and to provide a household biomass pyrolysis charcoal-gas co-combustion method and a stove. The method and stove pyrolysis temperature and conversion process are easy to control, the gas production speed is fast and stable, the gas quality is stable, and the calorific value is high
