A method for adjusting the environment of a tunnel kiln and a temperature self-regulating device in the kiln

Abstract

The invention discloses a tunnel kiln environment conditioning method and a device of automatically adjusting the temperature in a kiln. The tunnel kiln environment conditioning method includes the following steps: S1, environmental information acquisition equipment is arranged in a tunnel kiln, wherein the environmental information acquisition equipment is used for acquiring environmental parameters of the environment to be conditioned in the tunnel kiln and sending the environmental parameters to a controller; S2, the controller generates an environment conditioning command according to the environmental parameters acquired by the environmental information acquisition equipment, and sends the environment conditioning command to an environment conditioning execution mechanism; and S3, the environment conditioning execution mechanism conditions the environment in the tunnel kiln according to the environment conditioning command sent from the controller. The tunnel kiln environment conditioning method can control the angle of a temperature adjustment burner, the combustion gas injection rate, the angular rate of the temperature adjustment burner, the kiln tail blast rate, and the like, of the tunnel kiln, and can perform sintering research on various refractory materials, thus increasing diversity of research.

Description

technical field [0001] The invention relates to a method for regulating the environment of a tunnel kiln and the tunnel kiln. Background technique [0002] The burners of the original tunnel kiln are directly installed on both sides of the tunnel kiln or on the kiln roof. The position of the burner is fixed, that is, the angle of the burner cannot be adjusted. The kiln walls on both sides and the kiln roof are piled with refractory materials. In the original tunnel kiln, the temperature in the kiln can only be changed by changing the injection speed of air and gas and extensively adjusting the blast speed in the kiln. Its fatal disadvantages are: [0003] 1. The original tunnel kiln changes the temperature in the kiln by changing the air and gas velocity. The sintering temperature has a large variation range, and the gas flow rate variation range cannot be accurately controlled, which affects the sintering quality of refractory materials. [0004] 2. In the original tunnel...

AI Technical Summary

Problems solved by technology

[0003] 1. The original tunnel kiln changes the temperature in the kiln by changing the speed of air and gas. The sintering temperature has a large range of changes, and the range of gas flow rate changes cannot be accurately controlled, which affects the sintering quality of refractory materials.

[0004] 2. In the combustion process of the original tunnel kiln, gas and air are not easy to turbulence, that is, it is not easy to fully mix, the combustion is not sufficient, and a large amount of polluting gas is generated during the process, and the amount of polluting gas generated is not easy to control

[0005] 3. The original tunnel kiln has a low degree of intelligence, and cannot adjust the speed ratio of air and gas according to the temperature change in the kiln in real time, and the adjustment of the burner angle, etc.

[0006] Fourth, the original tunnel kiln has a large temperature difference between the upper and lower sides of the kiln when sintering refractory materials, and the effect of taking various measures to reduce the temperature difference in the kiln is not obvious
