Abstract
The utility model relates to the heat pipe technology, in particular to a device for the dump radiating of a coal house used in power plants, thermal power plants, power plants, chemical industries, the metallurgy, the ceramics, coal mines, etc. the device for dump radiating of the coal house of the utility model comprises fixing steel plates, heat pipes, the evaporation section of the heat pipes, the condensation section of the heat pipes. The fixing plate is connected with the heat pipes by screw connection, and the evaporation section of the heat pipe is arranged inside the coal house. The condensation section of the heat pipe is provided outside the coal house. The utility model makes use of the high efficiency heat transfer performance of the heat pipe for transferring the heat quantity inside the coal house to the upper end of the heat pipe (condensate); then the heat quantity can be emitted to air via the heat pipe.
Description
Technical field
The utility model relates to hot pipe technique, refers in particular to the device in a kind of coal-hole dump heat radiation of sector applications such as thermal power plant, steam power plant, dynamics factory and chemical industry, metallurgy, pottery, colliery.
Background technology
Industries such as thermal power plant, steam power plant, dynamics factory and chemical industry, metallurgy, pottery, colliery must be stocked enough coal amounts because production needs at present.Generally be advisable with the consumption of stocking 10-15 days.In order to reduce the loss of storage coal, must carry out appropriate storage and keeping to coal, to prevent that not only the weathering of coal, rain from decreasing and windage loss, also must prevent the oxidation and the spontaneous combustion of coal.Particularly the oxidation of coal and spontaneous combustion do not cause enough attention at present as yet.The insider knows, coal after the extraction, is subjected to the effect of oxygen in the air under the mine, and surface staining bears redness of the skin or complexion or white scale, and moisture content increases, and lump coal is broken into powder, and this phenomenon becomes the oxidation of coal.According to the related data introduction, the oxidation rate of coal and the rising of temperature are closely related.Emit a large amount of heats during oxidation of coal in the dump,, the dump temperature is risen and when being increased to ignition point, spontaneous combustion just takes place if can't accumulate in the dump to spreading everywhere.What is particularly worth mentioning is that, when the dump temperature greater than 60 ℃, oxidation is accelerated, and during near 100 ℃, gets final product spontaneous combustion in 1-2 days.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, provide a kind of and utilize that heat pipe efficiently absorbs heat, the excellent in performance of heat transfer and heat release, heat in the dump is distributed to greatest extent in atmosphere, thereby the temperature in the reduction dump prevents the heat abstractor of self-ignition of coal pile.
The technical solution of the utility model is: the heat abstractor that the utility model is arranged in the dump comprises fixation steel plate, heat pipe, heat pipe evaporator section, heat pipe condenser section, wherein fixation steel plate and heat pipe are with being threaded, heat pipe evaporator section is located in the coal vertebra, and heat pipe condenser section is located at outside the dump.
The utility model has utilized the efficient heat transfer performance of heat pipe, and the heat in the dump is transferred to the upper end (condensate liquid) of heat pipe, distributes in air by heat pipe and fin thereof then.
Description of drawings
Accompanying drawing is the utility model structural representation
The specific embodiment
By accompanying drawing as can be known, the heat abstractor that the utility model is arranged in the dump (4) comprises fixation steel plate (6), heat pipe (2), heat pipe evaporator section (5), heat pipe condenser section (3), wherein fixation steel plate (6) and heat pipe (2) are with being threaded, heat pipe evaporator section (5) is located in the coal vertebra (4), and heat pipe condenser section (3) is located at outside the dump (4).Steel plate described in the utility model (6) is provided with internal thread, and is provided with externally threaded heat pipe (2) and is connected, and also is provided with radiating fin (1) on the heat pipe (2).
The utility model designs, makes length and suitable heat pipe and the quantification of thickness according to the height and the floor space of dump under the normal condition.The most handy lower boiling working medium of hydraulic fluid in the heat pipe such as fluorine Lyons etc. are for well.Fixation steel plate is layed in coal-hole ground, and steel plate is preferably fixing tight with foundation bolt.The size of steel plate, thickness and piece number are decided by the area of coal-hole or size, the quantity of dump.There are internal thread and heat pipe evaporator section top external screw thread to be complementary on the steel plate.The plane steel plate that will have internal thread is fixed, then with in the internal thread on the external screw thread precession steel plate on heat pipe evaporator section top, till tightly fixing.When unloading coal, coal unloaded as far as possible around heat pipe, pile up.
Claims (2)
1, a kind of heat abstractor of coal-hole dump, the heat abstractor that it is characterized in that being arranged in the dump (4) comprises fixation steel plate (6), heat pipe (2), heat pipe evaporator section (5), heat pipe condenser section (3), wherein fixation steel plate (6) and heat pipe (2) are with being threaded, heat pipe evaporator section (5) is located in the coal vertebra (4), and heat pipe condenser section (3) is located at outside the dump (4).
2, the heat abstractor of a kind of coal-hole dump according to claim 1 is characterized in that described steel plate (6) is provided with internal thread, and is provided with externally threaded heat pipe (2) and is connected, and also is provided with radiating fin (1) on the heat pipe (2).
