Abstract
The utility model discloses a coal bunker temperature measuring device comprising a hot spot detector, and is characterized in that CT2C temperature sensors are employed by the hot spot detector, each CT2C temperature sensor is held by four stainless steel wire ropes, stainless steel hoops are fixed along a length direction with an interval of 25 CM, the coal bunker temperature measuring device can carry out continuous detection, a hot junction is not fixed, the device is always corresponding to online highest temperature, through using the stainless steel wire ropes for protection and fixation, the device is inserted into the middle of a coal dump, thus comprehensive temperature detection in a coal bunker can be realized, there is no temperature measuring blind area, the sensors do not need an external power supply and can be used in a hazardous area, and calibrating the scene is not needed.
Description
Technical field
The utility model relates to a kind of coal bunker temperature measuring equipment.
Background technology
Along with power industry develops rapidly, thermal power plant's single-machine capacity is to high parameter, large unit future development, and for guaranteeing the unit coal-burning demand, coal-fired power plant is stored scale also progressively to large capacity development.For a change the open-air coal yard of tradition wants corresponding increase site area to improve coal storage, reduce problems such as ambient air pollutions of waterhead, closed silo, coal yard can improve the utilization of area rate with it, increase storage coal capacity, dwindle floor area, environmental-protecting performance is outstanding, with and support equipment advanced technology, program control horizontal high and extensively used.Closed silo, coal yard advantage are a lot, but shortcoming is outstanding too: spontaneous combustion easily occurs in closed space coal storage dump; The coal seam temperature raises and causes easily spontaneous combustion naked light and flue gas, and closed silo, coal yard safety in production are had serious threat.
Existing coal bunker temperature measurement schemes is for to use PT100 to be detecting element, and each silo bottom arranges 8 points for measuring temperature, and the middle part arranges 4 points for measuring temperature, disposes altogether 12 temperature sensors.The temperature sensor installation site: the coal breakage cone section of (inner conical surface) is respectively installed 4 temperature sensors on the activation feeder that adopt silo external cylindrical surface side (male cone (strobilus masculinus)), silo bottom, and 4 temperature sensors are installed at the silo middle part, insert dark 100mm.Be limited to 70 ℃ on the alarm temperature, the temperature alarming upper limit is adjustable.The temperature sensor position all arranges platform, guardrail and service aisle up and down; The shell of temperature sensor should be made by stainless steel.
Intelligent temperature of each silo configuration is patrolled and examined alarm, realizes that the temperature monitoring data show, report to the police.Be connected to be installed in the instrument cabinet and show on the spot.Transfer to computer control system by communication interface.
Prior art mainly comprises following defective: there is the thermometric blind area in the point type thermometric; Can only measure the dump surface temperature, insertion depth is shallow, and the coal seam internal temperature can't be measured; Thermometric is counted many, and is the bulkhead plug-in type, frangibility; Installation and maintenance are complicated; Field wiring is many, and maintenance is large.Described defective value must improve.
The utility model content
The utility model purpose provides a kind of coal bunker temperature measuring equipment, addresses the deficiencies of the prior art, and need not the sensor power supply be need not to carry out on-site proving, realizes comprehensive detection coal seam internal temperature.
The technical solution of the utility model is as described below: a kind of coal bunker temperature measuring equipment, comprise hotspot detector, and it is characterized in that described hotspot detector adopts CT
2The C temperature sensor, every CT
2The C temperature sensor is embraced by four stainless steel wire rope, and along its length, fixes a stainless steel larynx hoop every 25CM.
Coal bunker temperature measuring equipment according to said mechanism is characterized in that, in coal bunker, settles two or more described hotspot detector.
The utility model beneficial effect: adopt CT
2The hotspot detector of C temperature sensor can continuous detecting, and hot junction is fixing; all the time corresponding with the maximum temperature on the line, by adopting the protection of stainless steel wire rope fixing, insert in the middle of the dump; can realize like this temperature detection in the comprehensive coal bunker, not have the thermometric blind area.In addition, adopt CT
2The hotspot detector of C temperature sensor, sensor need not external power supply, can use in the hazardous location, also need not the scene is demarcated.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described; should understand; this embodiment is the explanation to the utility model structure and principle thereof; but not to its restriction of carrying out; without departing from the concept of the premise utility; any deduction or replace to the utility model is made all should be considered as belonging to protection domain of the present utility model.
A kind of coal bunker temperature measuring equipment of the present utility model as shown in Figure 1 and Figure 2, comprises hotspot detector, it is characterized in that, described hotspot detector adopts CT
2 C temperature sensor 1, wire diameter are 3MM, every CT
2 C temperature sensor 1 is embraced by four stainless steel wire rope 2, and stainless steel wire rope 2 diameters are 10MM, and along its length, fixes a stainless steel larynx hoop 3 every 25CM, and stainless steel larynx hoop 3 diameters are that 25MM-32MM is adjustable.Stainless steel wire rope 2 is not only played a supporting role, and protects simultaneously CT
2 C temperature sensor 1, and wear-resisting, tension, shock resistance.
Described CT
2 C temperature sensor 1 adopts thermo-sensitive material that two K type thermocouple wires are wrapped up, and then externally wraps up the Inconel600 outer protective sleeve.CT
2The C temperature sensor utilizes the thermoelectric effect principle, can produce continuously and its length corresponding millivolt signal of maximum temperature in the scope in one's power, can be used to the maximum temperature of continuous probe guarded region.CT
2The C temperature sensor carries out Real Time Monitoring to the variation of temperature.
Coal bunker temperature measuring equipment according to said mechanism is characterized in that, in coal bunker, settles two or more described hotspot detector.
As shown in Figure 3, Figure 4, a kind of concrete scheme according to described coal bunker temperature measuring equipment is as follows:
The utility model adopts CT
2The C temperature sensor can continuous detecting, and hot junction is fixing, corresponding with the maximum temperature on the line all the time, by adopting the protection of stainless steel wire rope fixing, inserts in the middle of the dump, can realize like this temperature detection in the comprehensive coal bunker, does not have the thermometric blind area.And sensor need not external power supply, can use in the hazardous location, also need not the scene is demarcated.
