Description

Technical Field

[0001] The present invention relates to the technical field of thermal insulation materials, and particularly to an apparatus and method for preparing an inorganic thermal insulation material from titanium gypsum. Background Art

[0002] Titanium gypsum is a waste residue mainly composed of dihydrate gypsum generated by adding lime to neutralize a large amount of acidic wastewater in the production of titanium dioxide by the sulfuric acid method to treat the acidic wastewater.

[0003] In recent years, in the sewage treatment process of non-ferrous smelting, the lime / calcium carbide sludge method is used as an arsenic removal agent, and polyferric sulfate is used as a flocculant. Under high pH conditions, while generating iron arsenate with arsenic in the sewage, iron hydroxide colloid will also be produced. The arsenate in the solution and iron hydroxide can also undergo adsorption coprecipitation. After pressure filtration, it becomes a viscous sludge, which is red, yellow or waste gypsum due to the presence of trivalent iron ions. Because it is similar to the sewage acid treatment process of titanium dioxide production by the sulfuric acid method, this non-ferrous smelting sewage acid neutralization slag mainly composed of dihydrate gypsum is also called titanium gypsum.

[0004] The inorganic thermal insulation material of titanium gypsum is a new type of inorganic thermal insulation material made from mineral titanium dioxide and gypsum as the main raw materials through a special process. It has excellent thermal insulation performance, waterproof and breathable performance, fire resistance, as well as good environmental friendliness and sustainability. At the same time, the inorganic thermal insulation material of titanium gypsum also has the advantages of light weight, simple construction, and long service life. It is widely used in the fields of building exterior wall insulation, roof insulation, pipeline insulation, cold storage insulation, etc.

[0005] The inorganic thermal insulation material of titanium gypsum can recycle industrial waste residues, which is beneficial to environmental protection. Usually, it is obtained by a hydration reaction to get a casting material with a certain fluidity, and then cast into a mold to solidify into a plate. However, for the existing production equipment of the inorganic thermal insulation material of titanium gypsum, the connection between each equipment is not close enough, and the transfer of materials is usually completed manually, resulting in a decrease in output. Therefore, an energy-saving and environmental-friendly integrated equipment is needed to reduce the transfer and manual loss and improve the production efficiency of the inorganic thermal insulation material of titanium gypsum.
