Abstract

The invention discloses a rotational flow mixing device for a coal distillation furnace, which comprises a gas pipeline and rotational flow vanes, wherein the gas pipeline introduces cold air or hot flue gas into a mixing chamber; a plurality of the rotational flow vanes are arranged along the peripheral direction of a gas outlet of the gas pipeline, and a plurality of vane structures form a certain angle with the flowing direction of airflow; and a plane where the gas outlet of the gas pipeline is positioned is positioned outside a plane where the inner wall of the mixing chamber is positioned. In the rotational flow mixing device, the pipe mouth is provided with the rotational flow vanes, because gas generates rotational flow at the outlet, local low air pressure is formed at the pipe mouth and has the function of a sealing gasket on the gas in the mixing chamber, and the safety of the device is greatly improved.

Description

technical field [0001] The invention relates to a coal dry distillation device, in particular to a swirl mixing device for a coal dry distillation furnace. Background technique [0002] Dry distillation is a reaction process in which solid or organic matter is heated and decomposed in the absence of air. As a result of dry distillation, various gases, vapors and solid residues are produced. The mixture of gas and vapor is separated into gas and liquid after cooling. Dry distillation is a production process that humans have been familiar with and adopted for a long time, such as dry distillation of wood to make charcoal, and at the same time to obtain wood essence (methanol), wood acetic acid, etc. Dry distillation has always been an important method in the chemical processing of coal. After the coal is dry-distilled, the composition and aggregation state of the raw materials will change, and there are solid, gaseous and liquid substances in the product, and semi-coke, coa...
