Problems solved by technology

[0006] 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 rotary kiln. The safety factor brings great hidden dangers to the personal safety of operators
However, if temperature measuring devices are installed at multiple points of the rotary kiln, the installation and maintenance costs will be too high, which will seriously affect the economics of production
[0007] 2. It is impossible to predict the location of furnace lining peeling off: due to the inability to fully scan the kiln body covering the entire rotary kiln, it is impossible to physically model the various positions and areas on the rotary kiln body in the prior art, so that even when the temperature measuring device detects the temperature When the value changes, it is impossible to predict the corresponding location of furnace lining peeling, and it is also impossible to give a reference repair suggestion, which leads to the operator having to find the high temperature point of furnace lining peeling one by one in the whole kiln body, which is cumbersome and increases labor. strength
[0009] 1. The monitoring range is small: in the existing technology, a CO detector is generally installed at a certain point on the valve group platform of the rotary kiln. This method can only monitor the relevant parameters of a small part of the valve group platform of the rotary kiln. The monitoring range is very small and cannot Reflecting the real situation will reduce the safety factor of the rotary kiln valve group platform and bring great hidden dangers to the personal safety of operators
However, if CO detectors are installed at multiple points on the rotary kiln valve group platform, the cost will be too high and the operating space of the rotary kiln will be greatly reduced
[0010] 2. Occupy the operating space of the valve group platform of the rotary 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. During operation, it is very easy to trip over the cable jacket steel pipe and cause production accidents
[0011] 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

Description

technical field [0001] The invention belongs to the field of rotary kilns, and in particular relates to a dynamic monitoring device and a monitoring method for dangerous situations of a rotary kiln. Background technique [0002] Rotary kiln, also known as rotary calcining kiln, is a large-scale equipment in the core industry, which is widely used in building materials, metallurgy, chemical industry, environmental protection and other production industries. Its function is to use rotation and internal high temperature to calcine the materials in the kiln to form finished ore. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials. Cement kilns are mainly used for calcining cement clinker, which can be divided into two categories: dry production cement kiln and wet production cement kiln. Metallurgical and chemical kilns are mainly used for magnetization roasting of lean iron ore in iron and steel plants, oxida...
