Description

Fluidized cooling device

Technical Field

The utility model relates to the technical field of granule cooling, in particular to a fluidized cooling device.

Background

The fluidization technology is fully applied in the industrial high-temperature granule cooling process due to the high-efficiency gas-solid contact characteristic. Taking zinc smelting as an example, zinc concentrate is roasted by a roasting furnace to form overheated roasted sand of 900 ℃, and the overheated roasted sand can be conveyed to a subsequent working section after being cooled to 150 ℃. The prior art generally uses a rolling cooling cylinder to cool the calcine or a combination of a fluidisation cooler plus a cooling cylinder. The rolling cooling cylinder is a horizontal long cylinder which is slightly inclined downwards, the rotation of the rolling cooling cylinder drives the calcine to overturn and stir, so that the calcine moves along the length direction of the cylinder under the action of rotating force and gravity, and simultaneously contacts with a water cooling element outside the cylinder for heat exchange, and the cooling is completed in the transverse conveying process. The combination type is that a fluidization cooler is arranged in front of a cooling cylinder, and is mostly of a vertical jacket type, high-temperature granules enter the fluidization cooler, flow in the vertical direction after being fluidized and exchange heat with the dividing wall of a cooling water jacket outside the cylinder, then flow into the cooling cylinder through an inclined pipe, are further cooled, and change the flow direction from the vertical direction to the horizontal direction, so that the granules are conveniently conveyed to the subsequent working sections.

Therefore, the existing cooling device cannot meet the requirements of efficient cooling and conveying of materials simultaneously in a short flow.
