Feeding device for rice husk carbonization furnace

Abstract

The invention discloses an unloading device of a rice hull dry distillation furnace. The unloading device comprises a storage bin and a hopper, wherein a bottom valve and a bottom valve controller are arranged on the bottom of the storage bin; the bottom of the hopper is connected with a surrounding cover; an air outlet tube and a rectangular short tube are arranged on the side wall of the surrounding cover respectively; the rectangular short tube is connected with an air blower by an air hose; the bottom of the surrounding cover is connected with a spiral conveyor; the spiral conveyor comprises a main shaft and a machine enclosure; a spiral blade is arranged on the main shaft; the machine enclosure is divided into three sections; the machine enclosure sections at the two ends are cylindrical; the machine enclosure section on the middle part is conical; the spiral blade is also divided into three parts; the spiral blade parts at the two ends are distributed at an constant pitch; the spiral blade part on the middle part is distributed at a variable pitch; and the machine enclosure section on the middle part is uniformly provided with a plurality of radial fine holes within each pitch range; and the main shaft is connected with a drive motor on the side part at one side of the spiral conveyor. The unloading device is simple in structure, good in dust removal and gas exhaustion effect, and capable of improving purity of produced gas of the rice hull dry distillation furnace.

Description

technical field [0001] The invention relates to the dedusting technology of a rice husk carbonization furnace, in particular to a feeding device for a rice husk carbonization furnace. Background technique [0002] Oil and coal resources are non-renewable, and energy shortage has become a major problem that human beings must face. Biomass is recognized as one of the most potential non-traditional fossil resources in the world, rice husk is the most typical biomass, and my country's rice husk reserves are very rich. Rice husk gasification technology has attracted the attention of many scholars at home and abroad. Rice husk gasification is to use a gasification device to burn rice husks in an oxygen-deficient state, so that most of the combustible substances are converted into combustible gases such as carbon monoxide, hydrogen, and methane. The synthesis of raw gas is in line with my country's energy and environmental protection policies. At present, the rice husk gasifiers ...

AI Technical Summary

Problems solved by technology

At present, the rice husk gasifiers on the market produce combustible gas with high tar content and low carbon conversion rate, which makes it difficult to purify gas, block and corrode pipelines, and affect the normal operation of internal combustion engines or gas turbines

[0003] The root cause of the above problems is that the rice husk contains too many impurities and dust, and too much air is mixed in during combustion, which affects the purity of the gas produced.

In order to solve this problem, the Chinese patent CN202849329U proposes a feeding device for dry distillation cracking furnace. During the feeding process of raw materials, a suction fan is used to suck the dust in the raw materials, but the actual effect is not obvious
