Description
Technical field
The utility model relates to a kind of spontaneous combustion of coal Detection Techniques of stockpiling and storing based on wireless sensing, particularly relates to a kind of sniffer being applicable to detect real-time spontaneous combustion of coal situation in the coal accumulating vehicles, coal storage holdings.
Background technology
Coal, after certain hour is stored up in colliery or all kinds of coal yard, can cause self-ignition of coal pile, and the self-heating layer depth of general dump is less than 4m, and spontaneous combustion layer depth is less than 2.5m, because inclined-plane oxygen supply condition is better, first spontaneous combustion of coal is the easiest occurs on inclined-plane.The mine of China about 56% and the coal of coal seam extraction all also exist the danger of spontaneous combustion, particularly young coal, and inherent moisture is high, surface area is large, easy oxygen uptake, the spontaneous combustion cycle is short, not only spontaneous combustion can occur at coal yard, all spontaneous combustion can occur after even loading onto car, ship.
Because spontaneous combustion of coal needs regular hour and process, there is the universal law of self-growth, there is stronger disguise.A lot of coal storage and transport units does not often know that the coal in storage and transport process there occurs spontaneous combustion, realize until dump sends the white cigarette Shi Caineng that even takes fire, often burn a large amount of coal, cause economic loss and fire failure, also considerable influence is produced to not coal-fired matter, make it heat to reduce, affect enterprise and produce.
Along with the chemical reaction of series of complex in process of coal spontaneous combustion, CO, C can be produced

8deng gas, the size of these gas concentrations directly reflects the degree of oxidation of dump.In these gases, especially CO, its growing amount is large, occurs that temperature is low, and the pyrophorisity forecasting coal with CO, has sensitivity, regularity, detectability feature.
Except the generation of gas marker, the change of dump internal temperature is also the important indicator judging self-ignition of coal pile state.
Utility model content
The present invention is directed to prior art and do not consider that gas marker concentration affects this index to coal spontaneous combustion, propose a kind of spontaneous combustion of coal detection system of stockpiling and storing based on wireless sensing.
Based on a spontaneous combustion of coal detection system of stockpiling and storing for wireless sensing, comprise detecting unit, metal probe, trunk steel pipe, Zigbee wireless transport module, height adjusting valve, bracing frame, routing node and monitor;
Described trunk steel pipe is vertically fixed on bracing frame by height adjusting valve, trunk steel pipe end is provided with disposed thread, a holding tank is had in metal probe, detecting unit is arranged in the holding tank of metal probe, the disposed thread of metal probe one end and trunk steel pipe end is connected, the other end of metal probe installs filter mantle, and the signal output part of detecting unit is connected with Zigbee wireless transport module, and Zigbee wireless transport module is connected with computing machine by routing node;
Described detecting unit comprises temperature detecting unit and gas concentration detecting unit;
Described temperature detecting unit comprises thermopair and temperature transmitter; Thermopair is connected with the input end of temperature transmitter, the output termination Zigbee wireless transport module of temperature transmitter, and the wireless network transmissions be made up of Zigbee wireless transport module is to routing node, and routing node sends into monitor by serial port;
Described gas concentration detecting unit comprises gas concentration sensor and consistency transmitter; Gas concentration sensor is connected with consistency transmitter input end, the output termination Zigbee wireless transport module of gas concentration sensor, and the wireless network transmissions be made up of Zigbee wireless transport module is to routing node, and routing node sends into monitor by serial port;

The utility model compared with prior art, beneficial effect is: the change of temperature when this device can detect dump low-temperature oxidation simultaneously, and the situation of change of the gas marker CO concentration produced, and temperature signal and gas concentration signal are delivered to monitor fast; The utility model can realize long-range continuous real-time monitoring spontaneous combustion of coal, and highly sensitive, and detection cost is low, economical rationality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and the purpose of this utility model and effect will become more obvious.
As shown in Figure 1, a kind of spontaneous combustion of coal detection system of stockpiling and storing based on wireless sensing, comprises detecting unit, metal probe 1, trunk steel pipe 2, Zigbee wireless transport module 5, height adjusting valve 3, bracing frame 4, routing node and monitor;
Described trunk steel pipe 2 is vertically fixed on bracing frame by height adjusting valve 3, trunk steel pipe 2 end is provided with disposed thread, a holding tank is had in the metal probe 1 of the taper platform structure be made up of thermal conductive metallic material, detecting unit is arranged in the holding tank of metal probe 1, the disposed thread of metal probe one end and trunk steel pipe end is connected, be not designed with meticulous filter mantle with one end of trunk fastener for connection, the signal output part of detecting unit is connected with Zigbee wireless transport module 5, Zigbee wireless transport module is connected with computing machine by routing node.
Described detecting unit comprises temperature detecting unit and gas concentration detecting unit; Temperature detecting unit comprises thermopair and temperature transmitter; Thermopair is connected with the input end of temperature transmitter, the output termination Zigbee wireless transport module of temperature transmitter; Gas concentration detecting unit comprises gas concentration sensor and consistency transmitter; Gas concentration sensor is connected with consistency transmitter input end, the output termination Zigbee wireless transport module of gas concentration sensor.
After the graduated trunk steel pipe 2 of mark is inserted dump to be measured, the thermopair of metal probe 1 inside detects temperature, through connected temperature transmitter, temperature signal is changed into electric signal and is sent to monitor by wireless transport module by routing node, if the temperature detected arrives the alarm temperature of setting (as 70 DEG C, different because coal is different), monitor will give the alarm.
After trunk steel pipe 2 inserts dump, CO gas can be detected by gas concentration sensor by filter mantle, through the process of gas concentration transmitter, concentration signal is sent to monitor by wireless transport module by routing node.The concentration change trend of the CO that gas concentration sensor is mainly monitored can judge the stage of coal spontaneous combustion, and the threshold value reaching setting when CO gas concentration can be reported to the police.
This spontaneous combustion detecting devices carries out early warning and monitoring to the situation of coal spontaneous combustion in temperature and CO gas concentration two, when the inner a certain regional temperature of dump or the arbitrary index of gas concentration reach set threshold value, can report to the police, staff needs to make corresponding preventive measure, so more effectively prevents the generation of fire.
