Rotary kiln, also known as rotary calcining kiln are a kind of core industry large scale equipments, are widely used in building materials, metallurgy, change
In the production industries such as work, environmental protection.It is to carry out calcination processing to material in kiln with internal high temperature using rotation that it, which is acted on, to be formed
Finished product mine.Rotary kiln can be divided into cement kiln, chemical metallurgy kiln and limekiln by processing material difference.Cement kiln is mainly used for calcining
Clinker divides dry production cement kiln and wet production cement kiln two major classes.Chemical metallurgy kiln is then mainly used for metallurgy industry
The poor iron ore magnetic roasting of steel plant, chromium, josephinite oxidizing roasting, refractory factory roasting high-aluminium vanadine mine and aluminium manufacturer's roasting are ripe
Material, aluminium hydroxide, chemical plant roast the classes mineral such as chrome ore and chromite ore fine.Limekiln (i.e. active lime kiln) is for roasting steel
The active lime and light dolomite of factory, ferroalloy works.
Rotary kiln is made of kiln body, burner apparatus and driving device three parts.Kiln body is again by steel construction and kiln lining two
Part forms, and steel construction is responsible for erecting the general frame of rotary kiln, kiln lining be responsible for heat-insulated, heat preservation of the rotary kiln in production and
Fire resisting.It may be said that the service life of kiln lining and quality directly affect the operating rate, energy consumption index and roasting effect of whole rotary kiln
Rate.Kiln lining, by the continuous souring of thermal-flame and hard material, often has local stripping in rotary kiln produces for a long time
The phenomenon that falling occurs, would not be to the use of rotary kiln if can find and be handled (online hot gunning) at the first time at this time
It adversely affects., whereas if can not find that kiln lining peels off operating mode and its peeling position for a long time will at the first time
It causes the monoblock kiln lining in the region to fall, and the kiln shell in the region can be caused to aoxidize, get rusty, whole rotary kiln is caused to have to stop
It only produces, thus, the peeling diagnostic techniques of kiln lining is of crucial importance for the stable yields of rotary kiln, natural labor.

Method can only monitor the relevant parameter of rotary kiln valve group platform very small part area, and monitoring range is very small, can not reflect true
Real situation, can reduce the safety coefficient of rotary kiln valve group platform, prodigious hidden danger is brought to the personal safety of operative employee.But such as
Carbon monoxide detector is arranged in fruit at multiple points of rotary kiln valve group platform, then cost can be caused excessively high again, and can be greatly decreased
The operating space of rotary kiln.
2, the operating space of rotary kiln valve group platform is occupied：Carbon monoxide detector needs are connected with signal cable, power cable
Ability normal operation, and cable needs outer steel pipe, these optional equipments can occupy limited operating space significantly, and operate
Work in operation, easily is tripped to form production accident by cable jacket steel pipe.
3, the leak positions CO can not be prejudged：Under the prior art, when carbon monoxide detector detects CO leakages, system can not prejudge
Go out the position of CO leakages.If wanting to learn CO leakage points, operative employee would have to hold portable carbon monoxide detector that position is gone one by one
Test, it is not only cumbersome but also increase labor intensity.
