Device for preparing hot-press carbon-containing pellet

Abstract

A device for preparing hot-pressed carbon-containing pellets, belonging to the field of metallurgical technology. The invention includes an iron fine powder heating machine. The iron fine powder heating machine and the pulverized coal heating machine are connected in series through a hot air pipe. The outlet of the iron fine powder heating machine is connected with the inlet of the iron powder buffer hopper. The outlet of the pulverized coal heating machine It is connected to the inlet of the pulverized coal buffer hopper; the outlet of the iron powder buffer hopper and the outlet of the pulverized coal buffer hopper are connected to the mixing silo through the iron powder quantitative feeder and the pulverized coal quantitative feeder respectively; the outlet of the mixing silo It is connected to the inlet of the strong mixer, and the outlet of the strong mixer is connected to the inlet of the high-pressure hot briquetting machine through a pipeline; a waste gas removal system is set between the strong mixer and the high-pressure hot briquetting machine, and the pulverized coal The heating machine is connected to the hot flue gas dust removal system; a hot stuffy tank is provided below the outlet of the high-pressure hot briquetting machine.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, in particular to a device for preparing hot-pressed carbon-containing pellets. Background technique [0002] The main problems of current steel production are long process flow, high energy consumption and heavy environmental load. In the whole system of iron and steel production, the ironmaking system (including sintering, coking, blast furnace) is the most energy-consuming, and it also has a great impact on the environment (mainly CO 2 emission). In 2002, the energy consumption of the ironmaking system accounted for 69.4% of the entire steel industry, CO 2 Emissions accounted for 73.4% of the entire system. Among them, in the process of blast furnace production, its energy consumption and CO 2 The emissions accounted for 49.0% and 53.0% of the entire steel production system, respectively. [0003] With the continuous development of the iron and steel industry, the conditions of raw mate...
