Internal heating carbonization furnace

Abstract

The invention provides an internal heating carbonization furnace, which comprises a carbonization furnace main body and a wood gas cooling tower, wherein the carbonization furnace main body is a hollow carbon steel tank body, a thermal insulation layer is arranged outside the carbon steel tank body, the carbonization furnace main body is provided with a material inlet door plate, a wood gas outletand a combustion cylinder, the upper portion of the combustion cylinder is provided with a heat dissipating pipe extending into the carbonization furnace main body, the lower portion of the combustion cylinder is provided with a combustion inlet and a furnace grate, the bottom end of the combustion cylinder is provided with a fuel gas inlet, the wood gas outlet is communicated to the wood gas cooling tower through a wood gas pipeline, the other end of the wood gas pipeline is communicated to the fuel gas inlet on the bottom end of the combustion cylinder, and the middle portion of the wood gas pipeline is provided with a wood gas branch pipeline. According to the present invention, the rotary heat dissipating pipe is used, such that the structure is simple, the calcination is uniform, thewood gas generated during the charcoal calcining is fully utilized, the polluted air is not directly discharged, and the wood tar and the pyroligneous liquor in the wood gas are collected and used toturn the waste wood gas into treasure so as to substantially improve the profits of carbon-making enterprises.

Description

technical field [0001] The invention relates to the technical field of charcoal production equipment, in particular to an internal heating carbonization furnace. Background technique [0002] The production process of the retort carbonization furnace mainly includes the processes of feeding materials, heating and calcination, cooling, and the release of finished products. The traditional dry distillation carbonization furnace technology is backward, the heating and calcination process needs to use a large amount of high-quality fuel, the energy waste is serious, and the large amount of smoke and harmful gases discharged during the raw material carbonization process have caused great pollution to the environment. Therefore, it is necessary to The existing dry distillation carbonization furnace is improved to meet the needs of the market and users. Contents of the invention [0003] The invention provides an internal heating carbonization furnace, which completely solves th...
