Calcinator

Abstract

The invention relates to a calcinator. The calcinator comprises a burning cylinder, a calcination cylinder, a discharge pipe, a solid-liquid separation cylinder and an unloading piece. A furnace chamber is formed in the calcination cylinder, the burning cylinder is arranged on the outer side of the calcinations cylinder in a sleeving mode, and an annular burning chamber is formed between the burning cylinder and the calcination cylinder; a feed pipe and a plurality of burning nozzles are arranged on the burning cylinder, the solid-liquid separation cylinder is arranged at the end of the discharge pipe, and the unloading piece is arranged on the solid-liquid separation cylinder; a connecting end is arranged on the side wall of the solid-liquid separation cylinder and connected to the end of the discharge pipe, a smoke hole and a discharge hole are formed in the two ends of the solid-liquid separation cylinder correspondingly, and the discharge hole communicates with the smoke hole; and a discharge cavity is formed in the discharge piece, the discharge cavity communicates with the discharge hole, and the discharge cavity is an annular cavity. According to the calcinator, over burning is avoided, heat conduction efficiency is high, and unloading is facilitated.

Description

technical field [0001] The invention relates to a calciner. Background technique [0002] A calciner is a piece of equipment used for high-temperature processing, such as in ironmaking, recycling rare metals, producing catalysts or calcining pellets. Calciners are generally used for processing small particle materials, for example, materials that are sensitive to oxidation, combustion, explosion and heat. The furnace body of the calciner is provided with a combustion chamber, and the particles to be calcined are accommodated in the annular combustion chamber and calcined in the annular combustion chamber. However, since the flame directly contacts and burns the particles in the annular combustion chamber, the particles around the flame are easily heated locally, resulting in excessive combustion of the particles. Moreover, due to the blocking of the particles adjacent to the flame, the remaining particles are heated unevenly, and the heat conduction efficiency is not high....

Problems solved by technology

However, since the flame directly contacts and burns the particles in the annular combustion chamber, it is easy to locally heat the particles around the flame, resulting in excessive combustion of the particles

Moreover, due to the blocking of the particles adjacent to the flame, the remaining particles are heated unevenly, and the heat conduction efficiency is not high.

In addition, it is difficult to unload the calciner
