Novel dry distillation device based on gas combustion principle

Abstract

The invention relates to a novel dry distillation device based on a gas combustion principle, comprising a dry distillation furnace at a upper part and a coke discharge device at a lower part, a gatevalve is arranged between the dry distillation furnace and the coke discharge device, the dry distillation furnace is cylindrical, and the dry distillation furnace comprises a low-temperature dry distillation section at an upper part and a high-temperature dry distillation section at a lower part; the inner wall of the low-temperature dry distillation section is provided with a plurality of disturbing walls protruding inwards, the disturbing walls are symmetrically or unsymmetrically disposed along the inner wall of the furnace; the outer wall of the high-temperature dry distillation section is annularly provided with a plurality of air inlets, the air inlets communicate with an annular chamber arranged at the furnace wall, the annular chamber communicates with a plurality of first spray holes arranged in the inner wall, the first spray holes are arranged in a staggered way, and the annular chamber, the first spray holes and the inner wall together form an annular air-distribution perforated wall; and the center of the high-temperature dry distillation section is provided with a cylindrical central air-distribution perforated wall, and the central air-distribution perforated wall is connected with the inner wall of the furnace through a support mechanism under the center air-distribution perforated wall. The design of the annular air-distribution perforated wall achieves more uniform and reasonable air flow distribution than other chamber designs such as square perforated walls.

Description

technical field [0001] The invention relates to a dry distillation device, in particular to a novel dry distillation device based on the principle of gas combustion, and belongs to the technical field of coal and oil shale processing. Background technique [0002] Coal belongs to fossil non-renewable energy. Since the last century, it has been an important energy and mineral product in China. It has played an important supporting role in my country's economic and social development. The utilization of coal is mainly concentrated in combustion power generation, coke manufacturing, residential heating, coal chemical industry and so on. With the rapid development of the new environmental protection situation and the rise of the new energy industry, the proportion of fossil energy including coal in the national economy is constantly decreasing, and with the emergence of new technologies, the new utilization of coal has also been greatly improved. develop. Oil shale is also an ...
