SINGLE TYPE SHAFT KILN FOR LIME CALCINATION

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single type vertical kiln for calcining limestone to obtain quicklime, and in particular, to ensure a sufficient combustion space between the burner and the limestone to improve combustion conditions and to force combustion gas inside the kiln for calcining limestone. It is an object of the present invention to provide a single-type vertical kiln that can produce quicklime of quicklime quality by improving the firing conditions by rotating the furnace and rotating the furnace body.;The single type vertical kiln according to the present invention for solving the above problems is a preheating cylinder in which a combustion chamber and a preheating zone are formed in an inner space, a plastic cylinder in which a firing table is formed in an inner space, and a cooling cylinder in which a cooling table is formed in the inner space. A furnace body including a furnace, and an inner space in the furnace body in the up-down direction in the combustion chamber and the baking zone, the lower end of which is open toward the cooling zone, and the upper end of which extends outward through the furnace lid of the furnace; And a portion of the combustion gas formed in the central portion of the furnace body, wherein a part of the combustion gas that has been fired in the firing table is supplied from the lower side of the furnace together with the air preheated while cooling the quicklime. It is supplied back to the combustion chamber via the space, and between the inner and outer peripheral surfaces of the inner cylinder portion Along the inner longitudinal portion and the plurality of pipes are provided, the combustion air supplied through the lower end of the pipe is characterized in that by way of the pipe in which the furnace supplied to the burner provided in the cover.;Vertical kiln, combustion chamber, rotary drum, inner cylinder, combustion gas, limestone
