Light calcined magnesia calcinator suspension calcination device

Abstract

The invention discloses a light calcined magnesia calcinator suspension calcination device. The device comprises a kiln body, the bottom of the kiln body is provided with a gas material inlet pipe, the top of the kiln body is provided with a gas material outlet pipe, the side wall of the kiln body is provided with a fuel inlet, the fuel inlet is communicated with a fuel nozzle in the kiln body, a magnesite ore powder and an air preheating device are arranged in front of the gas material inlet pipe and a gas material separation device is arranged in rear of the gas material outlet pipe. The light calcined magnesia calcinator suspension calcination device solves the problem of blocky material solid-gas phase counter-current movement of the existing light calcined magnesia calcination reverberatory kiln. Reaction products and waste gas go through the gas material outlet pipe on the top, are discharged and then enter the gas material separation device. The materials are in a suspension state, rise along with hot gas, fast react and can be uniformly sintered so that the product has high activity and good quality. The light calcined magnesia calcinator suspension calcination device realizes large scale, continuous and fast production of light calcined magnesia, has a simple structure, is convenient for operation, can be controlled flexibly and realizes uniform sintering. The product has high activity and good quality.

Description

technical field [0001] The invention relates to the technical field of light-burned magnesia roasting kilns. Background technique [0002] Magnesite is an important national strategic resource. my country's magnesite reserves account for about 24% of the world's reserves, ranking first in the world. Although my country is a big country producing magnesite resources and magnesia materials, due to years of blind mining, high-grade magnesite ore is increasingly scarce, and the production of light-burned magnesia is still stuck in the original extensive production mode. The production enterprises have simple equipment and lack of technology. Standards, thermal systems and operating procedures are mainly manual operation based on experience, which is labor-intensive, serious environmental pollution, unstable product quality, low added value of products, and resources cannot be comprehensively utilized. The root cause of the problems in my country's magnesite industry is the back...
