Biomass Horizontal Rotary Core Carbonization Furnace

Abstract

The invention relates to the technical field of carbonization furnaces, in particular to a biomass horizontal rotary core carbonization furnace, wherein the inner cylinder is provided with a rotary core push twist shaft, and the outer peripheral wall of the rotary core push twist shaft has spiral blades, and the rotary core push twist shaft The front end of the twisted shaft hangs outside the inner cylinder and is driven by a motor to rotate. The front end and rear end of the inner cylinder respectively hang outside the outer cylinder. The front end of the inner cylinder is provided with a raw material inlet, and the rear end of the inner cylinder is provided with a first outlet. A heating chamber is enclosed between the inner cylinder and the outer cylinder. The rear end of the outer cylinder is provided with a heating medium inlet, and the front end of the outer cylinder is provided with a heating medium outlet. A plurality of stirring columns are vertically arranged on the spiral blades. There is a spiral deflector, the bottom of the spiral deflector is provided with a plurality of rolling support units, and the bottom of the spiral deflector forms a rollable support fit in the direction of the cylinder length through the rolling support units and the inner wall of the outer cylinder. The invention has the advantages of high raw material char formation rate, improved production efficiency, guaranteed charcoal product quality and long service life.

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.
