Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection and resource utilization, and particularly relates to a device for mineralizing and carbon sequestering with mine solid waste. Background Art

[0002] With the continuous development of the industrial field, mines have been extensively exploited, and a large amount of solid waste has been generated from mining activities. These solid wastes not only occupy a large amount of land resources but may also pollute the environment. Therefore, developing a device that can utilize mine solid waste for mineralizing and carbon sequestering for the recycling of solid waste. After the solid waste is recycled, it needs to react in a reaction kettle. The following deficiencies exist in the process of recycling and reacting the solid waste: First of all, after the solid waste is crushed, it needs to be transported to the reaction kettle by a transport vehicle, and the feed inlets of the crusher and the reaction kettle need to be manually closed respectively. This process increases the cost of transporting the solid waste and the operation steps; Secondly, harmful gases are generated in the reaction kettle, and the harmful gases spreading in the air are likely to pollute the surrounding environment and damage the health of the nearby population; In addition, the smaller particles in the solid waste are likely to block the carbon dioxide discharge holes, resulting in a reduced contact range between the solid waste and carbon dioxide and an extended reaction time of the solid waste.

The crushing motor is controlled to drive the crushing roller to rotate to crush the solid waste. After the reaction gas enters the inside of the spray pipe, it is sprayed towards the inner wall of the inner tank. The bent setting of the spray pipe prevents the solid waste from blocking the spray pipe, enabling the solid waste to react evenly and quickly.

After the cover plate 701 seals the upper part of the positioning housing 501, the crushing roller 503 can be effectively protected. When the second rack 706 moves, it controls the valve to close automatically; The pressure relief gas inside the reactor 1 can effectively enter the detector 302. Select a model of the detector 302 that can detect gases in the prior art according to needs. When the detector 302 detects harmful gases, it will automatically alarm. At this time, the staff should replace the filter element in time. When replacing, the corresponding valve needs to be closed.
