Cooling device of biomass carbonization furnace

Abstract

The invention discloses a cooling device of a biomass carbonization furnace. The cooling device comprises a cooling chamber, a feeding hopper, a discharging hopper, a cold air inlet pipe and a stirring roller, a feeding hopper is arranged at the top of the cooling chamber, a discharging hopper is arranged at the bottom of the cooling chamber, a plurality of stirring rollers are horizontally arranged on the upper portion of an inner cavity of the cooling chamber in parallel, the two ends of each stirring roller are rotationally arranged on the inner side wall of the inner cavity, and a drivingmotor is arranged at the end of each stirring roller so as to drive the stirring roller to rotate. A plurality of air outlet pipes are arranged on the inner side walls of an inner cavity, of which theouter sides are provided with cold air inlet pipes, of the cooling chamber, and a plurality of air outlet holes are formed in the sides, away from the cold air inlet pipes, of the air outlet pipes atequal intervals. According to the device, the problems that in the prior art, when a cooling device of a biomass carbonization furnace is used for cooling, materials in the cooling chamber cannot becomprehensively cooled, cold air penetrating into the materials is little, the cooling effect is not obvious, long-time working cooling is conducted, the temperature in the cooling chamber is greatlyincreased, and the cooling quality is obviously reduced are solved.

Description

technical field [0001] The invention relates to the technical field of biomass carbonization furnaces, in particular to a cooling device for biomass carbonization furnaces. Background technique [0002] my country is a big producer of charcoal, with an annual charcoal output of up to 10 million tons. With the rapid development of the national economy, the demand for charcoal is also increasing year by year. At the same time, my country is still a large agricultural production country, with about 7 billion tons of biomass waste such as crop stalks every year, but its utilization rate is only 20%. wasted. Biomass carbonization technology can effectively convert these biomass wastes into biomass carbonization products - combustible gas and biochar, that is, charcoal, which can greatly reduce the demand for natural wood, thereby effectively protecting forestry resources. Biomass carbonization is the use of thermochemical reaction principles to prepare green renewable fuels usin...

AI Technical Summary

Problems solved by technology

[0003] When the cooling device of the biomass carbonization furnace in the prior art is used for cooling, the materials in the cooling chamber cannot be fully cooled, the deep cold air inside the materials is less, the cooling effect is not obvious, and the cooling is performed for a long time. The temperature is greatly increased, and the cooling quality is significantly reduced
