A low-temperature chlorination furnace inter-furnace slagging system and slagging method

Abstract

The invention discloses a low-temperature chlorination furnace inter-furnace slagging system and a slagging method, comprising a feeding pipe, a slag discharging pipe, a rotary valve, a first purge gas pipeline, and the first end of the feeding pipe connected to the first chlorine The slag outlet of the chemical furnace; the end of the slag discharge pipe is connected to the slag inlet of the slag collection equipment, and the first air inlet is set near the end of the slag discharge pipe; the rotary valve connects the end of the feed pipe and the slag discharge pipe The head end; the first purge gas pipeline is connected to the first air inlet, and the gas outlet of the first purge gas pipeline faces the slag inlet of the slagging equipment; the level of the slag outlet of the first chlorination furnace is higher than The horizontal height of the slag inlet of the slag collector. By setting the first purge gas pipeline, the cleaning of the slag inlet before slag discharge is realized. By setting the connection position and connection angle between the first purge gas pipeline and the slag discharge pipe, it is possible to effectively prevent the slag from entering the first blower. The scavenging pipeline can also make the slag inlet get better cleaned, and can effectively promote the slag discharge, making the slag discharge process smoother.

Description

technical field [0001] The invention relates to the technical field of titanium chloride industry, in particular to a low-temperature chlorination furnace inter-furnace slag discharge system and a slag discharge method. Background technique [0002] Titanium tetrachloride is the main raw material for industrial products such as chlorination titanium dioxide and sponge titanium. The main production methods at home and abroad include boiling chlorination and molten salt chlorination, both of which are produced by reacting titanium-containing raw materials with chlorine gas to generate tetrachloride. Titanium, for the production process of the low-temperature chlorination furnace, the raw materials used in the low-temperature chlorination furnace contain 10% to 20% of titanium, and the rest are impurity components. They need to be connected through a slag discharge system. The original slag discharge system is prone to failures such as material blockage and equipment corrosion ...
