Abstract

The invention discloses a calcination method of titanium gypsum. The method comprises the following steps: feeding titanium gypsum containing free water into a material charging bin, drying and crushing the titanium gypsum at 50 to 60 DEG C, then feeding the titanium gypsum into a furnace bin at 180 to 220 DEG C for high-temperature calcination, crushing, grinding and screening the titanium gypsum, and finally discharging the titanium gypsum from the furnace. The method effectively solves the problem of running away of dust namely titanium gypsum powder pollution in the traditional gypsum calcination, solves the problem of time and labor consuming in the traditional process through a one-step method, and is higher in efficiency. The whole process is accomplished in a closed mode and the problems are solved at one step. According to the method, heating is performed through a boiling furnace, fuel is sufficiently utilized, and the method is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the application field of building materials, and in particular relates to a method for calcining industrial waste titanium gypsum. Background technique [0002] Titanium gypsum is an industrial waste residue mainly composed of dihydrate gypsum produced by adding lime to neutralize a large amount of acid wastewater in order to treat acid wastewater when sulfuric acid method is used to produce titanium dioxide. Titanium gypsum is characterized by large surface area, high moisture content, and is not easy to dry. In recent years, with the rapid development of the titanium industry, the emission of titanium gypsum in my country has also increased rapidly. However, there is no reliable and effective method for the dehydration processing of titanium gypsum, so that titanium gypsum piles up into mountains, wasting cultivated land, and rainwater washes away , loss of the surface, polluting groundwater, at the same time, exposed to the ...
