Active lime shaft kiln gas burning modified production device

Abstract

The invention discloses an active lime shaft kiln gas burning modified production device. The active lime shaft kiln gas burning modified production device comprises a shaft kiln body, a chimney, a bag-type dust remover, a cone suction pipe, an air heat exchanger and an open groove. A base is arranged at the bottom of the shaft kiln body, a coal gas barrel is arranged at one end of the base, and acoal gas pipe is connected to one end of the bottom of the coal gas barrel in a sleeving mode, a beam type burner is connected to the bottom of the inner wall of the shaft kiln body in a sleeving mode, and a plurality of high-speed burners are arranged on two sides of the beam type burner. The active lime shaft kiln gas burning modification production device is simple in structure and convenientin operate, the coal gas barrel is used for pressurizing the internal coal gas, then a penetrating-power flame is generated through the beam type burner and the high-speed burners for calcination, thecalcination of stone materials is facilitated, the calcination efficiency is greatly increased, the phenomenon of uneven calcination due to a low temperature is avoided, and meanwhile a heat transfermethod of flue gas and the stone materials through internal components of the shaft kiln body for conduction, convection and radiation enables the upper layer of lime and the lower layer of lime to be calcined by heat more thoroughly.

Description

technical field [0001] The invention relates to the technical field of lime, in particular to an active lime vertical kiln gas-fired modification production device. Background technique [0002] Lime is an air-hardening inorganic gelling material with calcium oxide as the main component. Lime is made of products with high calcium carbonate content such as limestone, dolomite, chalk, and shells. Carry out calcination. [0003] Traditional lime shaft kiln production equipment cannot effectively increase the temperature required for lime calcination, which often results in lime calcination failure or uneven calcination. The flue gas calcined in the traditional lime shaft kiln is directly discharged into the atmosphere without filtering measures, causing air pollution and damaging the environment, and the lime shaft kiln has no cooling device, which can easily cause the temperature to drop and damage the internal components of the lime shaft kiln. In view of these defects, the ...

[0003] Traditional lime shaft kiln production equipment cannot effectively increase the temperature required for lime calcination, which often results in lime calcination failure or uneven calcination. The flue gas calcined in the traditional lime shaft kiln is directly discharged into the atmosphere without filtering measures, causing air pollution and damaging the environment, and the lime shaft kiln has no cooling device, which can easily cause the temperature to drop and damage the internal components of the lime shaft kiln. In view of these defects, the design A kind of active lime vertical kiln gas burning modification production device is very necessary
