Novel mineral powder decomposition kettle

Abstract

The invention provides a novel mineral powder decomposition kettle. The decomposition kettle comprises a shell, a fixed plate, a decomposition chamber, supporting legs, a carbon dioxide conveying tube, a calcium carbonate conveying tube, a heatproof protection tube, a sealing ring, a heating plate, a temperature sensor, a control panel, a controller, a check valve and a push fan, wherein the fixedplate is mounted in the shell by bolts, the decomposition chamber is mounted in the fixed plate by bolts, and the supporting legs are welded to the lower part of the shell; and the carbon dioxide conveying tube is connected to the top of the decomposition chamber through a hole in the top of the shell, the calcium carbonate conveying tube is connected to one side of the decomposition chamber through a hole in one side of the shell, and the surface of the calcium carbonate conveying tube is bonded with the heatproof protection tube. The arrangement of the carbon dioxide conveying tube, the calcium carbonate conveying tube, the heating plate and the check valve makes the novel mineral powder decomposition kettle have the advantages of small size, small occupied space, simplicity in reaction, no clogging, high decomposition efficiency, realization of internal stirring at any time, and convenience in market promotion and application.

Description

technical field [0001] The invention belongs to the technical field of chemical experiment equipment, and in particular relates to a novel mineral powder decomposition kettle. Background technique [0002] A carbonization-decomposition method for directly extracting CaCO_3 whiskers from limestone powder. This method can use natural limestone powder as raw material to dissolve Ca(HCO_3)_2 through the action of water-soluble carbonic acid, and then obtain pyramid-shaped CaCO_3 whiskers with regular morphology through the decomposition reaction of Ca(HCO_3)_2 under elevated temperature conditions. Scanning electron microscope observation and X-ray diffraction analysis showed that the decomposition temperature of Ca(HCO_3)_2 had a significant effect on the microscopic morphology of CaCO_3 whiskers. 80°C will lead to the transformation of aragonite crystal phase to calcite crystal phase. The experimental results show that under the condition of 80℃ and 2h, the Ca(HCO_3)_2 decom...
