Problems solved by technology

The problem with this arrangement is that the cooling air is unevenly distributed on the horizontal section of the kiln, and segregation is prone to occur, resulting in uneven cooling of the lime product, affecting the quality of the lime product, and the overheated lime product may even burn out the finished product transfer at the bottom of the kiln belt

Embodiment 1

[0026] Such as Figure 1-2 As shown, the sleeve kiln lime cooling device in this embodiment includes a main pipe 3 , a ring pipe 4 and a branch pipe 5 , and the main pipe 3 is equipped with a regulating valve 1 and a flow meter 2 . The ring pipe 4 surrounds the kiln body 8 . A week along the ring pipe 4, several branch pipes 5 are evenly distributed, and the air outlets of the branch pipes 5 are located directly below the outlet of the lime funnel 9 on the top of the drawer type ash discharging device 10 . The branch pipe 5 is consistent with the number of the drawer type ash discharging device 10 and the uniform distribution angle of the horizontal section. The main pipe 3 and the ring pipe 4 are made of carbon steel, and the branch pipe 5 is made of carbon steel or stainless steel.

[0027] The lime cooling device of the sleeve kiln of this embodiment utilizes the negative pressure in the kiln body to draw normal-temperature air in the external environment into the cooling...

Embodiment 2

[0034] On the basis of the above embodiment, the annular pipe is a variable-diameter annular pipe, and the portion with the largest cross-sectional diameter and the portion with the smallest cross-sectional diameter of the variable-diameter annular pipe are arranged at both ends of the diameter of the annular pipe;

[0035] The cross-sectional diameter of the variable-diameter ring pipe changes uniformly from the smallest to the largest;

[0036] The air inlet is arranged at the part of the variable-diameter ring pipe with the largest cross-sectional diameter.

[0037] In this embodiment, the ring pipe is set as a ring pipe with variable cross-section, and the gas enters from the largest diameter, so that when the gas flows in the ring pipe, it will not cause each branch pipe to be damaged due to the different distances between the branch pipes and the intake pipe. The gas flow rate is different. Because the gas enters from the largest diameter, when a part of the air flows o...

Embodiment 3

[0039] On the basis of the above embodiments, the annular pipe is an equal-diameter annular pipe, and a plurality of air inlets are arranged on the outside of the equal-diameter annular pipe, and each of the air inlets is evenly arranged along the circumferential direction of the annular pipe. In this embodiment, a number of air inlets are evenly arranged on the outside of the ring pipe, so that the flow rate of each air outlet can be guaranteed to be basically equal, and the gas segregation in the kiln body can be avoided.

[0040] Further, each of the air inlets communicates with a buffer container, and the volume of the buffer container is not less than 10 times the volume of the ring pipe. In this way, the air pressure of the buffered gas in the buffer container is approximately equal at each position, and the gas flow rate entering each air inlet is approximately equal, thereby making the gas pressure in the ring pipe more uniform and the flow rate of each branch pipe more...

Abstract

The invention discloses a lime cooling device for a sleeve kiln. Mainly aiming at the problem that a lime product cannot be uniformly cooled by a sleeve kiln in the prior art, a lime cooling device for the sleeve kiln, which can be used for uniformly cooling the lime product, is provided. The lime cooling device comprises an annular pipe, wherein the annular pipe surrounds a kiln body; the inner side of the annular pipe is uniformly provided with a plurality of air outlet ports along the axial direction; the kiln body is provided, corresponding to the air outlet ports, with a plurality of through holes; a plurality of branch pipes are arranged in the through holes in a penetration manner; the outer walls of the branch pipes are in seal fit with the side walls of the through holes; all the branch pipes and lime hoppers in the kiln body are arranged in a one-to-one correspondence manner; cretins ends of the branch pipes are communicated with the air outlet ports of the annular pipe, while the other ends of the branch pipes are arranged just under lower ports of the corresponding lime hoppers; the annular pipe is provided with an air inlet port; the air inlet port is communicated with an air inlet pipeline. By using the lime cooling device, the segregation and the short circuit of a cooling gas can be avoided; the lime product can be uniformly cooled.

Description

technical field [0001] The invention relates to a sleeve kiln lime cooling device. Background technique [0002] The sleeve-type shaft kiln originated from Beckenbach Wilmannsteller Company in Germany, and has been widely used in the fields of metallurgy, building materials, and chemical industry in the world. Practice has shown that the sleeve-type shaft kiln has a simple structure and a high degree of automation. The operation and maintenance are convenient, the pollution is small, and the quality of lime products is high. It is an advanced kiln type with broad development prospects. [0003] The interior of the lime kiln body is divided into a preheating zone, a calcination zone and a cooling zone in sequence from top to bottom. The sleeve type lime kiln is operated under negative pressure, and the normal temperature air in the external environment passes through the cooling air duct and is sucked into the cooling zone at the bottom of the kiln body to cool the calcined ...
