What is a cement rotary kiln?
Cement rotary kiln is the main equipment for cement clinker dry and wet production lines. The rotary kiln is composed of a cylinder body, a supporting device, a bearing device with a stop wheel, a transmission device, an active kiln head, a kiln tail sealing device, a coal injection pipe device and the like. The kiln body of the rotary kiln is inclined to a certain level, and the entire kiln body is supported by a supporting roller device.
Why can thermal imaging camera detect cement rotary kiln?
Compared with other stationary industrial furnaces (such as downdraft kiln, tunnel kiln, lime furnace, etc.), the service life of rotary kiln lining is shorter. There are 2 reasons for this:
1 The mechanical effect of the rotating kiln on the lining causes some damage to the lining;
2 During the operation of the rotary kiln, the bonding between the bricks is not strong, resulting in the interaction between the lining bricks and the short service life of the rotary kiln liner. The infrared thermal imager can evaluate the damage of the lining of the rotary kiln: The temperature field of the outer wall of the rotary kiln can be detected by the thermal imager to understand the degree of damage of the lining under the operating conditions of the device, thereby providing a reference for the development of the repair program.
The infrared thermal imager detects the advantages of the cement rotary kiln lining. The cement rotary kiln is equipped with an on-line scanning temperature measuring device. The infrared thermal imager can replace the online scanning temperature measuring device to detect the kiln kiln lining.
1 The lining of the rotary kiln requires a certain period of time from the discovery of hidden troubles to the maintenance, and the use of an infrared thermal imager for periodic inspection (recommended for one inspection per class). Through the comparison of the captured heat maps, the damage status of the kiln liner can be quickly found.
2 The infrared thermal imager has the advantages of flexible and convenient operation, avoiding the installation of fixed platforms, wiring and other pre-construction, and lower equipment maintenance costs.
3 The replaceable memory card can facilitate the detection of multiple rotary kilns and the storage of heat map data.
Typical customers:
Advantages of infrared thermal imagers such as Conch Cement, Seal Cement, Asian Cement, Huaxin Cement, Lafarge Cement, etc. 1 The damage of the lining of the kiln cannot be detected with the naked eye, and the thermal imager can detect the temperature change of the housing and quickly Determine the fault.
2Fluke's patent-pending IR-Fusion technology not only captures infrared images, but also captures a digital photo at the same time, which is fused together to help identify and locate faults so that faults can be properly repaired in the first place.
3 The Fluke Ti thermal imaging cameras are equipped with powerful software for storing and analyzing thermal images and generating professional reports. With this software, key parameters such as emissivity, reflection temperature compensation, and color palette stored in images downloaded from the thermal imager can be adjusted, and these can all be performed in the office, improving the safety and convenience of the inspection.
Infrared Thermography for Rotary Kiln Lining Detection When using infrared thermal imaging to obtain a complete and clear infrared heat map, we recommend:
1 The maximum temperature of the surface of the shell of the rotary kiln is 350-370°C. Please select the thermal imager that is suitable for the temperature as much as possible. If the maximum temperature of the thermal imager is not enough, you can use the filter lens to attenuate the radiation energy, which can also be detected.
2 The parts of the shell of the rotary kiln are marked so that the hidden points can be located after the problem is found.
3 Heat maps should be stored and checked on a regular basis to help identify problems in a timely manner.
Method for detecting lining of external rotary kiln with red thermal imager
Rotary kiln is a key process equipment for calcining cement clinker, and kiln lining is a key factor in high-quality, high-production, low-consumption and long-term safe operation of rotary kiln production. The temperature is too high, and the thermal oscillation exceeds the General Assembly and seriously damages the kiln liner and kiln shell. In severe cases, it will cause burning of the kiln wall and lead to production stoppages. The infrared thermal imager can detect the damage of the kiln liner in time and avoid losses.
