Device for recovering fine-particle coal

The invention relates to a device for recovering fine-particle coal. The device comprises two functional sections, namely a coal preseparation section and smoke gas purification discharging sections, wherein a gas inlet static pressure box is arranged inside the coal preseparation section, and a coal preseparation bin is arranged at the bottom of the coal preseparation section; and the smoke gas purification discharging sections are arranged on two sides of a coal preseparation section box body and are communicated with the coal preseparation section box body, and each smoke gas purification discharging section comprises an airflow guide plate, a filter bag, a gas purification static pressure box and a fine-particle recovery bin. In the device for recovering the fine-particle coal, high-concentration and large-smoke-gas-volume dusty gas is subjected to preseparation by the coal preseparation bin, more than 90 percent of coal dust is collected, and after about 10 percent of gas containing coal dust is guided by the airflow guide plate and large-particle coal dust is subjected to preseparation, the gas containing coal dust is uniformly distributed to the surface of the filter bag of the box body in the middle to prevent the high-concentration dusty gas from washing the filter bag directly, so the recovery efficiency of the device for recovering the fine-particle coal can be improved, and the service life of the filter bag can be prolonged. The device for recovering the fine-particle coal is also provided with a series of safety protection facilities.
