Problems solved by technology

[0008] 1. The monitoring range is small and the installation cost is high: the existing technology can only monitor the surface temperature value of a small part of the area of ​​the lime shaft kiln, and the monitoring range is very small and cannot reflect the real situation. The safety factor of the kiln brings great hidden dangers to the personal safety of operators
However, if temperature measuring devices are installed at multiple points of the lime shaft kiln, the installation and maintenance costs will be too high, which will seriously affect the economics of production
[0009] 2. Unable to predict the location of furnace lining spalling: Since the kiln body covering the entire lime shaft kiln cannot be fully scanned, physical modeling of each position area on the lime shaft kiln body cannot be performed under the existing technology, so that even when the temperature measuring device detects When the temperature value changes, it is impossible to predict the corresponding location of the furnace lining peeling off, and it is also impossible to give a reference repair suggestion, which leads to the operator having to search for the high temperature point of the furnace lining peeling off one by one throughout the kiln body, which is cumbersome and cumbersome. increased labor intensity
[0011] 1. The monitoring range is small: in the existing technology, a CO detector is generally installed on the ground or at a certain point of the kiln body. This method can only monitor the relevant parameters of a small part of the area of ​​the lime shaft kiln. The monitoring range is very small and cannot reflect the real In some cases, the safety factor of the lime shaft kiln will be reduced, which will bring great hidden dangers to the personal safety of the operators.
However, if CO detectors are installed at multiple points in the lime shaft kiln, the cost will be too high and the operating space of the lime shaft kiln will be greatly reduced
[0012] 2. Occupy the operating space of the lime shaft kiln: the CO detector needs to be connected with the signal cable and the power cable to operate normally, and the cable needs to be covered with steel pipes. These additional equipment will greatly occupy the limited operating space, and the operator will , it is very easy to be tripped by the steel pipe of the cable jacket and cause a production accident
[0013] 3. Unable to predict the location of CO leakage: under the existing technology, when the CO detector detects CO leakage, the system cannot predict the location of CO leakage
If you want to know the CO leakage point, the operator has to take a portable CO detector to test the location one by one, which is cumbersome and increases the labor intensity

Abstract

The invention discloses a dynamic danger monitoring device for a lime shaft kiln. The lime shaft kiln comprises a shaft kiln body, a feeding device and a blower device, the feeding device is arrangedat the top of the shaft kiln body, and the blower device is arranged at the bottom of the shaft kiln body. The dynamic monitoring device comprises a patrol device, a detector and a controller; the patrol device comprises a patrol robot, a driving device and a rail around the shaft kiln body; the detector is mounted on the patrol robot, the patrol robot is driven to operate on the rail by the driving device, and the detector transmits monitoring signals received around the shaft kiln body to the controller in real time. The invention further provides a monitoring method of the dynamic monitoring device. The dynamic monitoring device is wide in monitoring range and small in occupied operating space, and the monitoring method is simple, convenient and high in monitoring efficiency.

Description

technical field [0001] The invention belongs to the field of lime shaft kilns, and in particular relates to a dynamic monitoring device and a monitoring method for dangerous situations of lime shaft kilns. Background technique [0002] The iron and steel industry, calcium carbide industry, alumina industry, refractory materials and other industries are all major lime consumers. In the past two years, these industries have developed rapidly, and their annual output has basically increased at a rate of more than 20%. This has caused lime to be in short supply, and has also stimulated the rapid development of lime production equipment - lime kiln. [0003] The main component of limestone is calcium carbonate, while the main component of lime is calcium oxide. The basic principle of burning lime is to use high temperature to decompose calcium carbonate in limestone into calcium oxide and carbon dioxide. Its process is that limestone and fuel are loaded into the lime kiln (if t...
