2results about How to "Guaranteed dust suppression effect" patented technology

This invention discloses a low-temperature carbon dioxide high-expansion foam dust suppression system and method for ore pass unloading. The dust suppression system includes a first high-expansion foam generator and a second high-expansion foam generator at the ore pass unloading port and ore bin, respectively. A foaming dust suppressant is mixed with inert carbon dioxide gas and a sulfide ore inhibitor to create foam with both dust suppression and ore spontaneous combustion inhibition properties. Because the foam contains an ore inhibitor, the spontaneous combustion tendency of ore dust upon contact with the foam is effectively reduced. Simultaneously, after the foam bursts, the low-temperature carbon dioxide gas within it lowers the ambient temperature and oxygen concentration within the ore pass, creating a low-temperature, low-oxygen environment and reducing the risk of ore spontaneous combustion and agglomeration within the ore pass. Furthermore, the low-temperature carbon dioxide generates natural convection, inducing airflow within the ore pass and accelerating foam diffusion. Therefore, this invention's low-temperature carbon dioxide high-expansion foam dust suppression system achieves synergistic prevention and control of dust and ore spontaneous combustion within the ore pass.

This disclosure relates to a dust suppression method, apparatus, electronic device, and storage medium. The method includes: acquiring first location information of a first vehicle, and based on the first location information, acquiring nozzle position information of at least one spraying device installed on both sides of the road on which the first vehicle is traveling; determining, based on the first location information and the nozzle position information, whether there is an intersection between a first detection range of the first vehicle and the current spraying range of the at least one spraying device; and, if it is determined that there is an intersection between the first detection range and the current spraying range, controlling the at least one spraying device to open or close based on its operating state. This disclosure can prevent vehicles from stopping or traveling at low speeds due to the need to avoid obstacles, thus ensuring both dust suppression effectiveness and vehicle operating efficiency.
