Embodiment 1

[0034] The coal pile hot spot detection method capable of automatic heat dissipation in this embodiment is applicable to hot spot temperature monitoring of open coal yards, strip-shaped closed coal yards, circular closed coal yards and silos. A plurality of heat pipes are buried in the coal pile along the depth direction of the coal pile; the heat pipes are used to realize the automatic heat dissipation of the coal pile, and the hot spot temperature of the coal pile is detected by intermittently detecting the temperature of the adiabatic section of the heat pipe and transmitting temperature data.

[0035] The detection method of the present invention, on the one hand, utilizes the super heat conduction characteristics of the heat pipe to timely derive the accumulated heat of oxidation of the coal pile, delay the rising trend of the hot spot temperature of the coal pile, and avoid the smoke and spontaneous combustion of the coal pile; on the other hand, due to the isothermal char...

Embodiment 2

[0044] The coal pile hot spot detection method capable of automatically dissipating heat in this embodiment differs from Embodiment 1 in that in this embodiment, multiple heat pipes are respectively buried in the coal pile along the depth direction of the coal pile, which means: laying a plurality of heat pipes In the edge area of ​​the coal pile, each heat pipe is buried in the coal pile along the depth direction of the coal pile, such as Figure 5 shown. The edge area of ​​the coal pile is a heat-prone area; the heat pipe is arranged in the edge area of ​​the coal pile, which can effectively monitor the hot spot area, so as to give an early warning of the hot spot of the coal pile; the heat pipe can also conduct heat outward to protect the coal pile structure from high temperature damage.

Embodiment 3

[0046] The difference between the coal pile hot spot detection method capable of automatically dissipating heat in this embodiment and the first embodiment is that in this embodiment, the intermittent detection of the temperature of the adiabatic section of the heat pipe and the transmission of temperature data refer to: the intermittent detection of the temperature of the adiabatic section of the heat pipe To obtain the hot spot temperature in the coal pile area where it is located, when the difference between the hot spot temperature and the ambient temperature is greater than or equal to the set value of the temperature difference, the hot spot temperature data is transmitted to the outside. Since there is no danger of spontaneous combustion when the temperature of the coal pile is low, it is not necessary to transmit the temperature data to the outside when the temperature of the coal pile is low. External transmission can save the power consumption of data transmission.

Abstract

The invention provides a coal pile hot spot detection method capable of automatically dissipating heat. The coal pile hot spot detection method is characterized in that a plurality of heat pipes are buried in a coal pile in a depth direction of the coal pile; and automatic heat dissipation of the coal pile is realized by utilizing the heat pipes, and the hot spot temperature of the coal pile is detected by intermittently detecting the insulation section temperatures of the heat pipes and transmitting temperature data. According to the method, the hot spot condition monitoring is more comprehensive; a real-time monitoring result can be obtained; the accumulated heat of the coal pile due to oxidation can be timely guided to outside, so that the rising trend of the hot spot temperature of thecoal pile is delayed; an element used for temperature detection does not need to be in contact with the coal pile, so that the service life can be effectively prolonged; and high applicability is achieved. The invention further provides a coal pile hot spot detector for realizing the method.

Description

technical field [0001] The invention relates to the technical field of coal pile hot spot temperature detection, and more specifically, relates to a coal pile hot spot detection method capable of automatically dissipating heat and a detector for realizing the method. Background technique [0002] During the stacking process, the coal will react with the oxygen in the air and release heat; in some special positions of the coal pile, when the heat released by the coal-oxygen recombination is greater than the heat released to the external environment, the temperature of the coal will gradually rise. High; the initial stage of coal spontaneous combustion generally rises slowly, but after reaching a certain level, the temperature will rise rapidly, and eventually evolve into spontaneous combustion. The spontaneous combustion of coal will not only cause economic loss and waste of resources, but also pollute the surrounding environment. Therefore, real-time monitoring of the tempe...
