Technical Field
[0001] The utility model belongs to the technical field of environmental protection dust suppression, in particular to a dry beach dust suppression system for a tailings pond of a ore dressing plant. Background Art
[0002] The tailings of the tailings pond of the ore dressing plant are discharged in front of the tailings dam. The tailings with larger particles are deposited in front of the dam. The tailings water flows to the tail of the lower tailings pond, and the tailings are continuously deposited. After hydraulic classification, a dry beach is formed in front of the dam of the tailings pond. The tailings in the dry beach of the tailings pond are fine in particle size. In the dry and rainless season, the wind will cause sand and dust to fly, polluting the environment. Moreover, the dry beach is large in area and difficult to manage. Under the current situation of increasingly stringent national environmental protection standards, it is imperative to deal with the dust problem of the dry beach of the tailings pond of mining enterprises.

The system can cleanly and efficiently utilize the return water in the tailings pond of the mineral processing plant, and cooperate with the set water distribution device to carry out dust reduction treatment on a large area of dry beach, effectively solving the dust problem of the dry beach of the mineral processing plant. However, the system can only achieve dust reduction treatment on a large area of dry beach through the water distribution device, and cannot distribute water according to the actual needs of dry beach dust reduction. In fact, dry beach dust will only occur when the dry beach is dry and at a certain wind speed. Summary of the invention
