Method.
Background technology
The industry such as steel and iron industry, calcium carbide industry, aluminum oxide industry, refractory material is all lime consumption rich and influential family, nearly 2 years this
Several industries are all the industries of high speed development, and annual yield is substantially to be increased with 20% or more speed.Which results in stones
Supply falls short of demand for ash, while also have stimulated the rapid development in lime production equipment-limekiln.
Lime stone main component is calcium carbonate, and lime ingredient is mainly calcium oxide.The basic principle of lime calcining is exactly
By high temperature, Decomposition of Calcium Carbonate in lime stone at calcium oxide and carbon dioxide.Its technical process is lime stone and fuel dress
Start to decompose to 850 DEG C after entering limekiln (if gaseous fuel is sent into through pipeline and burner) preheating, calcining completed to 1200 DEG C,
Again after cooling, it unloads outside kiln discharge, that is, completes the production of quick lime product.Different kiln shapes have different preheatings, calcining, cooling and
Unload grey mode.But some technological principles be it is identical i.e.：Material quality is high, lime quality is good；Fuel value is high, quantity consumes
It is few；Limestone granularity and calcination time are directly proportional；Quick lime activity degree and calcination time, calcination temperature are inversely proportional.
As lime stone production main equipment, limekiln mainly by kiln body, feeding device, distribution device, burner,
The compositions such as ash-discharging device, electric appliance, instrument control device, dust-extraction unit.It can be divided into multifuel combustion kiln according to fuel grade and (burn solid
Fuel, coke, coke powder, coal etc.) and gas burning kiln (i.e. burning blast-furnace gas, coke-stove gas, calcium carbide tail gas, producer gas, natural gas
Deng), it can be divided into lime lime shaft kiln, lime shaft kiln, lime sleeve kiln, LIME DOUBLE thorax kiln, lime twin beams according to the classification of kiln type
Kiln etc..Wherein, lime shaft kiln is using wide.
The structure of lime shaft kiln is as follows under the prior art：Cylindrical lime shaft kiln is installed on ground level, bottom
It is blower system, the wind of wind turbine bulging enters kiln body bottom by air inlet valve, annular passage, flows through kiln body from the bottom up, finally
It is discharged at the top of from kiln.There is material elevator by shaft furnace, at the top of certain angle of inclination connection landing ground and shaft furnace.In ground level

What the lime shaft kiln kiln body CO monitoring technology under the prior art was taken is static monitoring techniques method, i.e., in ground or kiln body
Carbon monoxide detector is arranged in optionally one or more position.Routine CO monitoring technology is in production application at this stage, usually have with
Lower three big defects：
1, monitoring range is small：Generally carbon monoxide detector is arranged in some of ground or kiln body points in the prior art, and this method is only
The relevant parameter of lime shaft kiln very small part area can be monitored, monitoring range is very small, can not reflect true situation, meeting
The safety coefficient for reducing lime shaft kiln, prodigious hidden danger is brought to the personal safety of operative employee.But if in the more of lime shaft kiln
Carbon monoxide detector is set at a point, then cost can be caused excessively high again, and the operating space of lime shaft kiln can be greatly decreased.
2, the operating space of lime shaft kiln is occupied：Carbon monoxide detector needs are connected with signal cable, power cable could just
Often running, and cable needs outer steel pipe, these optional equipments can occupy limited operating space significantly, and operative employee is grasping
When making, easily 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.
