Problems solved by technology

Due to the large fluctuation of the material at the upper interface of the low-temperature chlorination furnace bed, when the upper interface of the bed overflows and slags, the instantaneous slagging volume fluctuates greatly. 4 The product gas also brings environmental problems
Bed internal or bottom slag discharge can reduce TiCl 4 The product gas is lost, but the reliability of slag discharge is poor, and slag discharge is often blocked and the amount of slag discharge is uncontrolled, that is, the slag discharge cannot be stopped halfway. easily crusted and clogged
Since the furnace charge is powdery material, the temperature is 400-600°C, and the slag discharge material contains highly corrosive Cl 2 and TiCl 4 , resulting in unreliable slagging valve under the working condition of low temperature chlorination furnace

Abstract

The invention discloses a low-temperature chlorination furnace, and belongs to the technical field of metallurgical production equipment design and manufacturing. The low-temperature chlorination furnace which makes slag removing convenient and smooth and cannot cause TiCl4 product gas loss due to a slag removing structure is provided. The low-temperature chlorination furnace comprises a low-temperature chlorination furnace body with a smoke outlet formed in the top, and the low-temperature chlorination furnace further comprises an open type slag discharging structure and a disengaging plugging device; the open type slag discharging structure arranged on the lower portion of the low-temperature chlorination furnace body is opened and closed through the disengaging plugging device.

Description

technical field [0001] The invention relates to a low-temperature chlorination furnace, which belongs to the technical field of design and manufacture of metallurgical production equipment. Background technique [0002] Two commonly used slagging methods for low-temperature chlorination furnaces are bed overflow slagging and bed internal slagging. Due to the large fluctuation of the material at the upper interface of the low-temperature chlorination furnace bed, when the upper interface of the bed overflows and slags, the instantaneous slagging volume fluctuates greatly. 4 The product gas also brings environmental problems. Bed internal or bottom slag discharge can reduce TiCl 4 The product gas is lost, but the reliability of slag discharge is poor. There are often situations such as slag discharge blockage and uncontrolled slag discharge, that is, the slag discharge cannot be stopped halfway. It is easy to crust and block. Since the furnace charge is powdery material, t...
