Biomass horizontal rotary core carbonization furnace

Abstract

The invention relates to the technical field of carbonization furnaces, and especially relates to a biomass horizontal type rotary core carbonization furnace. A rotary core pushing and twisting shaft is arranged in an inner cylinder, spiral blades are arranged on the peripheral wall of the rotary core pushing and twisting shaft, the front end of the rotary core pushing and twisting shaft extends out of the inner cylinder in a suspended mode and is driven by a motor to rotate, and the front end and the rear end of the inner cylinder extend out of an outer cylinder in a suspended mode; a raw material inlet is formed in the front end of the inner cylinder, a first outlet is formed in the rear end of the inner cylinder, a heating cavity is defined between the inner cylinder and the outer cylinder, a heating medium inlet is formed in the rear end of the outer cylinder, a heating medium outlet is formed in the front end of the outer cylinder, a plurality of stirring columns are vertically arranged on the spiral blade, and a spiral flow deflector is arranged on the peripheral wall of the inner cylinder; and a plurality of rolling supporting units are arranged at the bottom end of the spiral flow deflector, and the bottom end of the spiral flow deflector and the inner wall of the outer cylinder form rolling type supporting fit in the cylinder length direction through the rolling supporting units. The carbonization furnace has the advantages of high raw material carbon yield, improved production efficiency, ensured carbon quality, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of carbonization furnaces, in particular to a biomass horizontal rotary core carbonization furnace. Background technique [0002] At present, the mature biomass carbonization furnaces in the market are mainly vertical fixed-bed carbonization furnaces and horizontal rotary kiln carbonization furnaces. Both of them use the heat energy released by hypoxic combustion to pyrolyze biomass raw materials, and there is a loss of fixed carbon. The amount of carbon is large, the carbon production rate is reduced, and the quality of carbon products cannot be guaranteed; at the same time, the associated gas is a product of oxygen-deficient combustion, which contains a large amount of nitrogen brought in by air, so the gas production is large, the temperature and calorific value are low, and the precipitation Tar, the use value and process reliability have been reduced, this kind of tar is hazardous waste, the treatment c...

Problems solved by technology

[0002] At present, the mature biomass carbonization furnaces on the market are mainly vertical fixed bed carbonization furnaces and horizontal rotary kiln carbonization furnaces, both of which use oxygen-deficient combustion to release heat energy to pyrolyze biomass raw materials, and there is a loss of fixed carbon. Large amount, low carbon production rate, and the quality of charcoal products cannot be guaranteed; at the same time, the associated gas is a product of oxygen-deficient combustion, which contains a large amount of nitrogen brought in by air, so the gas production is large, the temperature and calorific value are low, and the precipitation Tar, the use value and process reliability have been reduced, this kind of tar is hazardous waste, the treatment cost is high, and it threatens the ecological environment and personal health and safety; Defects such as low comprehensive utilization efficiency of material raw materials and high power consumption

The existence of these problems seriously restricts the further development of the carbonization industry of biomass raw materials.
