Abstract

The invention provides a coal distribution stirring device of a gasification furnace and a gasification furnace thereof. The coal distribution stirring device is arranged in the gasification furnace and positioned below a feed port on the top of the gasification furnace. The coal distribution stirring device comprises a coal distributor positioned on the upper part and a stirrer positioned on the lower part, wherein an opening on the top of the coal distributor is communicated with the feed port on the top of the gasification furnace; the bottom of the coal distributor is provided with a coal distribution tray; a coal distribution region is formed above the coal distribution tray; the region around the stirrer below the coal distribution disk is a gasification region of the gasification furnace; the coal distribution tray is provided with a through hole through which coal blocks can enter the gasification region from the coal distribution region; the coal distribution tray rotates along with a central shaft rod; and a coal distribution hood is also arranged in the coal distributor and flexibly connected to the central shaft rod. The invention also provides a gasification furnace comprising the coal distribution stirring device. The coal distribution stirring device and gasification furnace have the advantages of simple structure, low cost and high gasification efficiency, and are convenient to assemble.

Description

technical field [0001] The invention belongs to the technical field of coal gas generation, and in particular relates to a coal distributing and stirring device of a gasification furnace and a gasification furnace thereof. Background technique [0002] Coal gasification technology is a chemical technology that converts coal into combustible gas. It uses coal or coal coke as raw material, oxygen (air, oxygen-enriched or industrial pure oxygen) and water vapor as gasification agent. The process of converting the combustible part of coal or coal char into combustible gas through chemical reaction under high pressure. [0003] The combustible gas obtained after gasification by coal gasification technology is coal gas, and the equipment for gasification is called coal gasifier or gasifier. According to the different reactor forms of the gasifier, the gasifier can be divided into various types, such as fixed-bed gasifier, fluidized-bed gasifier, entrained-flow gasifier, molten-be...
