Abstract

The invention discloses an internal heat rotary kiln coal dry distillation device comprising a kiln body (4) with a feeding device (1) and a discharge device (5) respectively arranged on the two ends. The kiln body (4) has a sealed structure. A heating device (6), a rotation stabilization device (2) and a transmission device (3) are respectively arranged on the kiln body (4). The kiln body (4) is cylindrical. A pipe rack spiral plate (7) and a heating device (6) are arranged in the kiln body (4). The kiln body (4) is inclined towards the end provided with the discharge device (5), such that the kiln body end with the feeding device (1) is higher than the end with the discharge device (5). The internal heat rotary kiln coal dry distillation device provided by the invention has a simple and fully sealed structure. With the device, continuous production can be realized, and no dust, coal gas or pollutant is discharged to the surrounding environment during a dry distillation process. With the device, the production efficiency is greatly higher than that of prior arts.

Description

technical field [0001] The invention relates to the field of large-scale energy conversion rotary equipment, in particular to an internal heating type rotary kiln dry distillation coal device. Background technique [0002] Coal dry distillation technology refers to the process in which coal is heated and decomposed under air-isolated conditions to produce coke (or semi-coke), coal tar, gas and other products. [0003] The main process of low-temperature dry distillation of coal is as follows: when the temperature of the coal material is higher than 100°C, the moisture in the coal begins to evaporate; when the temperature rises above 200°C, the bound water in the coal is released; when the temperature is above 350°C, the Caking coal begins to soften, and further forms viscous colloids (peat, lignite, etc. do not occur); at 400-500°C, most of the gas and tar are precipitated, which are called primary thermal decomposition products; at 450-550°C , thermal decomposition continu...
