A biochar blanking device used in biomass production

Abstract

The invention discloses a biomass charcoal discharge device used in biomass production. The biomass charcoal discharge device comprises a furnace disc, wherein the furnace disc is arranged inside a hearth and is connected with a transmission mechanism; a plurality of charcoal discharge through holes are formed in the body of the furnace disc; a disturbance bridging breaking device is arranged on the furnace disc; a charcoal scraping device is arranged below the furnace disc; the furnace disc is driven to rotate by the transmission mechanism, and then the disturbance bridging breaking device isdriven to break accumulation of biomass charcoal; the biomass charcoal is dropped down from the charcoal discharge through holes and is conveyed to next procedures through the charcoal scraping device. Due to the arranged disturbance bridging breaking device on the furnace disc, the charcoal device below the furnace disc and the charcoal discharge through holes in the furnace disc, the biomass charcoal is always at a loosened state and is good in flowability and small in resistance, the pyrolysis velocity inside a furnace is increased, and the drying speed of materials inside an area is increased; a spindle casing and a dustproof cover are compactly connected, and the overall structure is reasonable in arrangement, convenient to maintain and long in service life.

Description

technical field [0001] The invention relates to equipment used for biomass production, in particular to a biomass charcoal blanking device used in biomass production. Background technique [0002] The crop straw is pyrolyzed in the micro-negative pressure pyrolysis gasification carbonization furnace at low temperature and anoxic. After a certain period of time and a certain temperature of thermochemical reaction, biomass charcoal and crude gas are produced. The crude gas is sent to the gas purification process, and the production The material charcoal is sent to the next charcoal treatment process. However, during the low-temperature anoxic pyrolysis process of crop straw in the micro-negative pressure pyrolysis gasification carbonization furnace, the biochar will accumulate together, which reduces the pyrolysis rate in the furnace and the drying speed of the material. As a result, there are few biochar raw materials in the next process, which seriously affects the output r...

Problems solved by technology

However, during the low-temperature anoxic pyrolysis process of crop straw in the micro-negative pressure pyrolysis gasification carbonization furnace, the biochar will accumulate together, which reduces the pyrolysis rate in the furnace and the drying speed of the material. As a result, there are few biochar raw materials in the next process, which seriously affects the output rate, but how to solve this problem, there is no report on equipment or technology in the prior art
