Biomass efficient clean charcoal and gas poly-generation device

Abstract

The invention relates to a biomass efficient clean charcoal and gas poly-generation device which comprises a furnace body. An ash outlet is formed in the bottom of the furnace body, a fire grate is arranged in the furnace body, and a heat conducting plate is arranged below the fire grate. A gasification chamber is arranged above the fire grate, a carbonization chamber is arranged between the fire grate and the heat conducting plate, and a combustion chamber is arranged below the heat conducting plate. A feeding auger and a gas inlet are arranged on the side wall of the combustion chamber. An automatic charcoal discharging device is arranged in the carbonization chamber and above and close to the heat conducting plate. A gas outlet is formed in the top of the gasification chamber, and a first material inlet is formed in the side wall of the gasification chamber. According to the invention, a heat graded utilization principle is adopted, high heat generated by combustion in the combustion chamber can firstly carbonize biomass at the bottom of the fire grate, and meanwhile, residual heat can carry out oxidation-reduction reaction on materials entering the gasification chamber at the upper layer, so that biomass gas is generated. Therefore, the defect that the existing fixed bed updraft and downdraft gasifiers only produce biomass gas or charcoal is overcome, the co-production of biomass gas and charcoal is realized, and the utilization rate of biomass is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of biomass energy utilization, in particular to the field of using biomass to prepare gas and charcoal. Background technique [0002] Energy and environmental issues have become the focus of global attention. With the rapid growth of energy consumption in China, the extensive use of fossil fuels has brought serious environmental pollution and ecological damage. Coal, oil, and natural gas are the main energy sources at this stage. Valuable organic chemical raw materials, the amount of resources is decreasing day by day, and the way that our country is generally used as fuel has caused a lot of waste. The development of clean renewable energy has become an urgent need for sustainable development. Among the renewable energy, it is the only clean energy that can be stored and transported on the earth. It has a large amount of resources, a wide distribution, and a huge development potential.

[0002] Energy and environmental issues have become the focus of global attention. With the rapid growth of energy consumption in China, the extensive use of fossil fuels has brought serious environmental pollution and ecological damage. Coal, oil, and natural gas are the main energy sources at this stage. Valuable organic chemical raw materials, the amount of resources is decreasing day by day, and the way that our country is generally used as fuel has caused a lot of waste. The development of clean renewable energy has become an urgent need for sustainable development. Among the renewable energy, it is the only clean energy that can be stored and transported on the earth. It has a large amount of resources, a wide distribution, and a huge development potential. Biomass gasification is one of the biomass energy utilization technologies. Among them, the fixed bed gasifier is It has the advantages of simple structure, easy manufacture, low cost, easy operation, suitable for bulk and large particle raw materials, and is suitable for rural use in China; this type of gasifier is divided into updraft gasifier and downdraft gasifier , due to structural problems, the calorific value of the gas produced by the up-suction gasifier is low, no charcoal is produced, and it is difficult to seal, and it is inconvenient to add materials. Excessive heat loss, insufficient gasification, etc.
