Dust treatment system for calcium carbonate production

Abstract

The invention relates to a dust treatment system for calcium carbonate production. The system is applied to the technical field of dust treatment equipment. The problem that the discharged water contains calcium carbonate powder and the water source and the soil quality are influenced due to the fact that existing equipment cannot treat calcium carbonate dust is solved. According to the technicalscheme, the system comprises a disc dryer, a dust collecting box and a dust filtering plate arranged in the dust collecting box; an atomization dust falling piece is arranged on the inner top wall ofthe dust collecting box; a drainage annular groove is formed in the upper surface of the dust filtering plate in the circumferential direction; a plurality of water seepage holes are formed in the bottom wall of the drainage annular groove at equal intervals; a suspension opening and closing piece for automatically blocking or opening the water seepage holes is arranged in the drainage annular groove; a dust suction hole is formed in the side wall, located in a dust falling chamber, of the dust collecting box; and a dust suction assembly for sucking wet dust is arranged between the dust suction hole and a feeding port of the disc dryer. Filtered wet dust particles are recycled and dried, so that resources are saved, calcium carbonate powder is prevented from being discharged along with water flow to influence the environment and soil quality, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of dust treatment equipment, in particular to a dust treatment system for calcium carbonate production. Background technique [0002] Calcium carbonate is an inorganic compound, commonly known as limestone, limestone, stone powder, marble, etc. At present, calcium carbonate often produces a large amount of dust in the actual production process. In order to prevent dust from spreading into the production workshop, it will pollute the working environment and affect The health of workers requires collection and disposal of these dusts. [0003] The existing authorized notification number is the Chinese invention patent of CN106140771B, which discloses a dust collection and treatment device, including a collection box body, a water level setting line is arranged in the collection box body, a dust collection port is arranged on the top of the collection box body, and the collection box body There is a dust colle...

AI Technical Summary

Problems solved by technology

[0004] But there is following defect in above-mentioned technical scheme: this dust collection treatment device directly feeds dust into water, because the dust that calcium carbonate produces in the production process is mostly the powder of calcium carbonate, and calcium carbonate is neutral, basically insoluble in water, Furthermore, calcium carbonate powder cannot be processed, resulting in the discharge of calcium carbonate along with the water in the process of water discharge, which affects the water source and soil quality. Therefore, further improvement is needed
