Embodiment Construction

[0045] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0046] Such as Figure 4 to Figure 9 As shown, the present embodiment provides a streamlined lime kiln, including a vertical kiln body 1 with a kiln chamber 11. The kiln chamber 11 is divided into a preheating zone, a calcination zone and a cooling zone from top to bottom, and the calcination zone corresponds to The inner wall of the kiln body 1 is a streamlined smooth surface 13 whose diameter tapers downward, and the curvature of the streamlined smooth surface 13 is greater than 0 and less than or equal to 1 / 3.

[0047] Wherein, the streamlined smooth curved surface 13 here refers to the smooth curved surface whose inner diameter continuously shrinks along with the height of the kiln body 1, and the model, volume and equipment ...

Abstract

The streamline lime kiln comprises a kiln body which is vertically arranged and provided with a kiln chamber, the kiln chamber is divided into a preheating zone, a calcining zone and a cooling zone from top to bottom, the inner wall, corresponding to the calcining zone, of the kiln body is a streamline smooth curved surface with the diameter gradually reduced downwards, and the curvature of the streamline smooth curved surface is larger than 0 and smaller than or equal to 1 / 3. According to the streamline lime kiln, the kiln wall effect caused by a traditional cylindrical straight tube type calcining zone kiln chamber is overcome, and the problems that the lime firing degree is uneven, the product quality fluctuates, safety production accidents happen, and the service life of equipment is damaged due to the kiln wall effect are effectively solved.

Description

technical field [0001] The invention relates to the field of industrial furnace lime kilns, in particular to a streamlined lime kiln. Background technique [0002] Compared with ordinary lime, activated lime has the advantages of high porosity, spongy shape and fine grain structure, and can complete the steelmaking slagging reaction faster. Maerz double-chamber kiln, sleeve kiln, and beam-type lime kiln are the main shaft kiln equipment for producing active lime at present. The raw material limestone enters the kiln and is calcined to obtain the product active lime. [0003] The calcination temperature of limestone must be strictly controlled within the range of 1100°C to 1150°C. If the temperature is too low, the decomposition of limestone is insufficient, which is called raw burning; if the temperature is too high, the grain structure of limestone grows too large, which is called overburning. Both raw burning and over-burning will lead to a decrease in the activity of li...
