Multifunctional biomass converter

Abstract

The invention relates to a multifunctional biomass converter. The converter is characterized in that the lower part of the bunker in a converter body is a pyrolytic chamber; a fire grate is arranged between the pyrolytic chamber and a combustion chamber which is at the bottom of the converter body; a heat exchange chamber is arranged between the bunker and the inner wall of the converter body; the upper part of the heat exchange chamber is provided with an airflow buffer chamber; air inlet channels are arranged between the bottom of the heat exchange chamber and a combustion chamber; pores communicated with the air inlet channels are distributed on the wall of the pyrolytic chamber; air inlets on the converter body wall are communicated with the air inlet channels; a carbon outlet is communicated with the pyrolytic chamber through a conduit; one ends of heat exchange tubes in the heat exchange chamber are communicated with the airflow buffer chamber, and the other ends of the heat exchange tubes are communicated with the combustion chamber after traversing through the air inlet channels; the top of the airflow buffer chamber is provided with a chimney; and the side wall of the heat exchange chamber is provided with a water inlet and a water outlet. The converter which can be used as a matching device for a system for the comprehensive utilization of biomass waste resource pyrolytic gasification or pyrolytic carbon gasification converts agricultural wastes into biological combustion gases, and hot water for villager's cooking, bathing and heating, and biological carbon powder and biological tar used for preparing fertilizers, pest (bacterium) killing agents and feed additives.

Description

technical field [0001] The invention relates to a combustion furnace, in particular to a multi-functional biomass conversion furnace which uses crop straw as the main biomass as fuel. Background technique [0002] my country is a large agricultural country, and a large amount of biomass resources such as crop stalks and chaff residues are produced in agricultural production and agricultural product processing. Traditional utilization methods are mainly used as household energy, feed, fertilizer, industrial raw materials and construction materials. With the modernization of agricultural technology and the rapid development of the agricultural economy, the rural living standards have been greatly improved and the way of life and production has changed suddenly. Such as coal, liquefied petroleum gas, etc.) have become the main cooking energy. Biomass straw is used in breeding, wild grass feed is replaced by commercial feed, biomass organic fertilizer required for agricultural...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to integrate the functions of multiple single-function biomass conversion equipment into one to produce a multifunctional biomass conversion furnace, which adopts conversion technologies such as reverse combustion, pyrolysis gasification, and pyrolysis carbonization. Combustion or carbon gasification pyrolysis under oxygen-rich or oxygen-deficient conditions, converted into hot water or bio-combustible gas, bio-tar, bio-acetic acid and hot water or bio-combustible gas, bio-char powder, bio-tar, bio-acetic acid and hot water , and realize automatic feeding, it can be used not only as a water heater, heating furnace, but also as a biomass gasifier or charcoal gasifier
