Abstract

The invention discloses a two-stage type powdered coal destructive distillation system which comprises a horizontally-arranged drying tube. An inlet and outlet of the drying tube are communicated with a feeding inlet and a coal discharging bin respectively. An outlet of the bottom of the coal discharging bin is connected with an inlet of a destructive distillation tube, the destructive distillation tube is horizontally arranged and arranged below the drying tube, and an outlet of the destructive distillation tube is connected with a semi-coke output bin with a bottom opening; a heating pipeline is arranged outside the drying tube, the heating pipeline surrounds the drying tube, and the outer wall of the drying tube is the inner wall of the heating pipeline; the two ends of the heating pipeline are provided with a gas inlet and a gas outlet respectively, a heat storage type radiation tube is fixedly arranged on the outer side of the destructive distillation tube, and hot raw coke oven gas enters the heating pipeline from the gas inlet, passes through the heating pipeline and enters the heat storage type radiation tube from the gas outlet. Due to the two-section type design, a heating channel is arranged outside the drying tube, so that the drying tube is heated, a heat source of the heating channel is hot raw coke oven gas, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of pulverized coal dry distillation system, and in particular relates to a two-stage pulverized coal dry distillation system. Background technique [0002] According to the prediction of my country's coal data, the total amount of coal resources within a vertical depth of 2000m in my country is 5,569.75 billion tons, of which the total amount of coal resources that have been detected is 1,017.645 billion tons, and the total amount of coal resources predicted is 4,552.1 billion tons. my country's coal resources are mainly concentrated in northern China, most of which are concentrated in Inner Mongolia, Shaanxi, Xinjiang, Gansu, Shanxi, Ningxia and other provinces (regions). The coal resources in the northern region are 5,184.282 billion tons, accounting for 93% of the total coal resources in the country; the total coal resources in other provinces are about 385.467 billion tons, accounting for only 6.92% of t...
