Cooling device in biomass carbonization furnace

Abstract

The invention discloses a cooling device in a biomass carbonization furnace. The cooling device comprises a tank body, wherein a plurality of support columns are fixedly connected to the lower end ofthe tank body, a feeding hole and a discharging hole are formed in the side surface of the tank body, a feeding funnel is arranged on the side wall of the feeding hole, and material controlling mechanisms are arranged at the feeding hole and the discharging hole; a rotating rod is rotationally connected to the upper surface of a base plate of the tank body, one end of the rotating rod penetrates through the side wall of the tank body and is fixedly connected with a movable plate, and a plurality of stirring rods are fixedly connected to the side wall of the rotating rod; and an air inlet is formed in the side wall of the tank body, and a heat dissipation fan is arranged at the feeding hole and is fixedly connected to the side wall of the feeding hole through a locking mechanism. Accordingto the cooling device, the heat dissipation of materials is realized, meanwhile, the speeds of feeding and discharging the material in and out of the tank body are controlled, and the heat dissipationfan can be conveniently cleaned, so that the cooling device in the biomass carbonization furnace is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of biomass carbonization furnace treatment devices, in particular to a cooling device in a biomass carbonization furnace. Background technique [0002] my country is a large country of charcoal production, with an annual output of 10 million tons of charcoal. 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 also a large agricultural production country, and the annual biomass waste such as crop straw is about 7 billion tons, but its utilization rate is only 20%, and hundreds of millions of tons of biomass waste such as branches, sawdust, and rice husks are wasted in vain. Biomass carbonization technology can effectively convert these biomass wastes into biomass Carbonization products - combustible gas and biochar, namely charcoal, can greatly reduce the demand for natural wood, thereby effectively protecting forestry res...
