Abstract
The invention relates to the technical field of carburant production, and relates to a carburant granulation system for comprehensive utilization of a fine powder of a coal calcination furnace. Gas discharge ports of the coal calcination furnaces, passing through a high-temperature fan and a material discharge room, is connected to a rotary kiln through heat preservation pipelines, a material discharge port at the lower part of the material discharge room directly faces a water-cooling feeding apparatus, a first feeding apparatus is arranged between the water-cooling feeding apparatus with thecoal calcination furnaces and a finished product packaging line, a material inlet end of the rotary kiln is connected with a settling chamber in a sealed and rotating manner, the lower part of the settling chamber is provided with a material falling hopper, a third feeding apparatus is arranged between the material falling hopper and a granulation raw material bin, an oven-dried material bin withtwo bin hoppers is arranged above the settling chamber, the two bin hoppers are inserted into the rotary kiln through the lower end of a main material discharge pipe, each of the two bin hoppers is equipped with a closing apparatus, the settling chamber is connected with a surface cooler, the surface cooler comprises a set of U-shaped pipelines and collection chambers, a conveying apparatus is arranged between a stirrer and a granulator, a material outlet of the granulator is opposite to a second feeding apparatus, and the terminal end of the second feeding apparatus is located above a carburant granulation granular material bin. The system has the advantages of waste heat utilization, pulverized coal utilization, and dust pollution reduction.
Description
Technical field: [0001] The invention relates to the technical field of carburant production, in particular to a carburant granulation system that comprehensively utilizes coal calciner fine powder. Background technique: [0002] Carburizers are divided into carburizers for steelmaking and carburizers for cast iron, and some other additives are also used, such as additives for brake pads, as friction materials. Carburizer is an additional carbon-increasing raw material for steelmaking and iron-making. High-quality carburizer is an indispensable auxiliary additive for the production of high-quality steel. [0003] There are many kinds of raw materials for carburizers, and the production processes are also different, including woody carbon, coal carbon, coke, graphite, etc., among which there are many small types under various classifications. High-quality recarburizers generally refer to graphitized recarburizers. Under high temperature conditions, the arrangement of carbon ...
