External cooling device for calcinator

Abstract

The invention relates to the field of high-temperature calcine, in particular to an external cooling device for a high-temperature calcinator. The external cooling device is composed of a left hollow half cylinder body cooling device body and a right hollow half cylinder body cooling device body. Independent hollow half cylinder bodies form annular main body structures. Partition plates are arranged in the hollow half cylinder bodies from bottom to top, and the hollow half cylinder bodies are divided into two and more cooling water cavities. Water flowing openings of the adjacent partition plates are arranged in a staggered mode. Each annular main body structure is provided with a water inlet pipe and a water outlet pipe. According to the external cooling device for the calcinator, the cooling effect can be improved, the equipment investment is reduced due to the fact that the height of a calcinator body of the calcinator is lowered, and the service life of the calcinator is prolonged.

Description

technical field [0001] The invention relates to the field of high-temperature calcination, in particular to an external cooling device for a high-temperature calcination furnace. Background technique [0002] Calcining petroleum coke at high temperature and holding it for a certain period of time is one of the effective methods for desulfurization. Desulfurization of petroleum coke through high-temperature calcination has far-reaching significance for environmental protection. Before anthracite is used in the production of carbon products, it must be calcined at high temperature to remove the volatile matter and reduce the resistivity of anthracite. With the diversification of calcined raw materials and products, the operating parameters of the calciner also change with the changes of calcined raw materials and products. The temperature in the electric calciner can reach 1700-3000°C, which is a simple and effective method for desulfurizing petroleum coke and reducing the re...

AI Technical Summary

Problems solved by technology

[0003] The calciner can be divided into three areas: preheating zone, high temperature zone and cooling zone according to the calcination of materials. Most of the existing technologies use the internal cooling method of water cooling bracket. The disadvantages are: firstly, this cooling method is due to Its large volume occupies the effective height of the furnace and causes waste. Secondly, in order to improve the cooling effect, the length of the cooling zone has to be increased, thereby increasing the height of the furnace body and the workshop, and increasing the investment in equipment.
