Granular biomass continuous carbonization device

Abstract

The invention relates to biomass energy production equipment and specifically relates to a granular biomass continuous carbonization device. The device comprises seven spiral conveyors which are successively arranged from top to bottom, wherein an airtight shell is arranged on the shell of each of the spiral conveyors; an airtight high-temperature gas conveying chamber is arranged as an inner chamber of the airtight shell; a zigzag granular biomass feeding channel is formed by end-to-end communicating the inner chambers of the two adjacent spiral conveyors; a zigzag high-temperature gas conveying channel is formed by end-to-end communicating the two corresponding adjacent high-temperature gas conveying chambers; a feeding hopper and a gas outlet pipe are arranged at the feeding end of the first spiral conveyor; a high-temperature gas outlet is formed on the airtight shell on the sixth spiral conveyor; a water outlet pipe, a water inlet pipe and a coke outlet are formed on the airtight shell on the seventh spiral conveyor. With such a structure, the granular biomass continuous carbonization device has the advantages that the gas can be continuously generated, the gas output is increased, the energy consumption is reduced and the manufacturing cost is lowered.

Description

technical field [0001] The invention relates to biomass energy production equipment, in particular to a granular biomass continuous carbonization device with simple structure, low manufacturing cost, low ash content of biomass gas and continuous production of biomass energy. Background technique [0002] At present, biomass is converted into biomass energy through retorts or gasifiers [biomass energy includes biomass coke and biomass gas], and then biomass gas is used for power generation. [0003] When the retort or gasifier with the existing structure is in use, the biomass is loaded into the inner cavity of the retort or gasifier, and then the gas is supplied through the air intake device and the gas is ignited for pre-combustion. Due to its own structure, The warm-up time is long and the energy consumption is high; it generally takes 11-15 hours to produce biomass charcoal with this type of structure, and the ash content of the biomass gas produced is relatively high.

[0003] When the retort or gasifier with the existing structure is in use, the biomass is loaded into the inner cavity of the retort or gasifier, and then the gas is supplied through the air intake device and the gas is ignited for pre-combustion. Due to its own structure, The warm-up time is long and the energy consumption is high; it generally takes 11-15 hours to produce biomass charcoal with this type of structure, and the ash content of the biomass gas produced is relatively high. If it is necessary for subsequent power generation, in addition to condensing and separating tar and wood vinegar In addition, ash reduction treatment is also required

[0004] The prior art retorts or gasifiers cannot produce continuously when carbonizing granular biomass such as rice husks, pulverized and dried granular green husks, rapeseed husks, etc. into biomass coke and biomass gas. The ash content of biomass gas is relatively high
