Description
Technical field
The utility model relates to a kind of measurement monitoring instrument, relates in particular to the intelligence instrument that a kind of large type coal field dump internal temperature is measured in real time, belongs to the temperature measuring instrument technical field.
Background technology
At electric power, metallurgy, coal and cement industry, the self-ignition of coal pile phenomenon of ground coal yard is general, and the oxidation of coal spontaneous combustion is great accident, has also reduced the value of coal.
The basic reason of dump oxidation and spontaneous combustion be since coal by airborne dioxygen oxidation.The elements such as the carbon in the coal, hydrogen will react at normal temperatures, generate combustible CO, CH4 and other alkane materials.Coal oxidation is again themopositive reaction, if heat can not in time dissipate, with the accumulation temperature of coal is raise, accelerates again conversely coal oxidation, emits more combustible and heat.When the heat accumulation of dump makes temperature rise to certain value, namely can cause combustible burning and cause spontaneous combustion.
Actual conditions according to the dump generation spontaneous combustion of above-mentioned electric power, metallurgy, coal and cement industry are seen, the position of spontaneous combustion occur neither on the top layer of dump, also not in the dump deep, and below the top layer of dump.
Generally, the structure of dump is divided into following level: cooling layer, oxide layer and the layer that suffocates.Coal is when naturally stacking, and General Central position particle is thinner, more past around particle thicker, corresponding, from the center toward around, the space is increasing, the ventilation and heat condition is become better and better, cooling layer and oxide layer are more and more thicker.Spontaneous combustion generally occurs in oxide layer.Therefore, can set a rational spontaneous combustion monitoring temperature to the oxide layer of different types of dump, by the measurement of this kind dump oxide layer temperature is predicted whether dump spontaneous combustion can occur.
Traditional apparatus for measuring temperature of coal stack is a certain degree of depth of pipe insertion dump with a both ends open, then a thermometer that connects with rope is put into tube interior, carry out temperature survey, the shortcoming of this thermometric is, be inserted in the process of oxide layer at pipe, an end that is used for pipe insertion dump is opening, the coal on dump surface is not because squeezed the opening of insertion of pipe, but stay the inside of pipe, although insert in the dump process at pipe, the coal on dump top layer can have to a certain degree sinking along with pipe, but it still is the coal on top layer, that is, what traditional measurement method was measured is the temperature of dump top layer coal, makes temperature-measuring part can not accurately measure the actual temperature of oxide layer.In addition, owing to do not have scale on the pipe, how dark the thermometric pipe need be inserted, and with operating personnel's micro-judgment, this also causes more accurately measuring a reason of oxide layer actual temperature entirely.This shows that traditional apparatus for measuring temperature of coal stack can not be measured the actual temperature of oxide layer more exactly owing to the defective of its structure.
Also used a kind of improved apparatus for measuring temperature of coal stack in the prior art at present, the one end is the heat-conducting metal head of built-in temperature-measuring part, connect the pipe that an outside surface is carved with scale on ferrule, the power lead of the temperature-measuring part of drawing in the pipe is connected with output line with the power supply that is arranged on the pipe other end and is connected with reading device.During measurement, with the heat-conducting metal head insertion dump of this pipe, can measure more exactly the temperature of a certain degree of depth dump oxide layer.But this device needs artificial execute-in-place, and measuring period is long, and inefficiency can't in time reflect all dump temperature regimes, very difficult realization coal yard digital management truly.
