Abstract
The utility model relates to a dry type hot tube flame arrestor which is used to prevent combustible gas inside a channel, which comprises a flame arrestor, a screen mesh and a hot tube with radiator-fans which is arranged on the upper, middle and upper of the screen mesh. The upper part of the hot tube extends outside the flame arrestor and is a cooling section, and the heat which is produced inside the channel can be rapidly transmitted outside the channel via the hot tube, therefore avoiding the explosion or combustion because of high temperature inside the channel. The utility model can make up for a deficiency that the heat of the combustion product can not be rapidly transmitted outside the channel in present common dry type flame arrestor, and has the advantages of good flame-retarding effect, good reliability, simple structure and low manufacturing cost.
Description
Affiliated technical field
The utility model relates to a kind of fire retardant device that prevents fuel gas detonation in the pipeline, especially a kind of dry type heat pipe spark arrester.
Background technology
At present, the structure of known dry type spark arrester generally is to be formed by silk screen, filler or corrugated plating etc.The mechanism of extinguishing realizes fire-retardant purpose thereby utilization flame in slit flow channel can suffocate.But because the heat of flame combustion product is often higher in the pipeline,, the flammable mixture of spark arrester opposite side is caught fire, make fire-retardant inefficacy, cause catastrophic accident to take place if heat can not be spread out of in the short time.Simultaneously, woven wire is burnt sometimes under the high temperature, can influence the service life of spark arrester.
Summary of the invention
The purpose of this utility model is, in order to overcome the existing low deficiency of dry type spark arrester heat-transfer capability, the utility model provides a kind of novel dry type spark arrester, this spark arrester is at the existing pipeline that utilizes---the gap fire extinguishing flame of silk screen (or filler etc.), reach on the basis of method of purpose of back-fire relief, utilize special start-up characteristic that heat pipe had and good special thermal conduction characteristic, the heat of flame combustion in the pipeline is delivered to beyond the spark arrester fast, avoids spark arrester opposite side combustibles fire burns.Because heat pipe is under the non-started state, the capacity of heat transmission is very little, can avoid heat unnecessary loss in the pipeline.
Technical solution scheme of the present utility model is: a kind of dry type heat pipe spark arrester, comprise back-fire relief body, silk screen, and be provided with the heat pipe of fin in the silk screen, be provided with sealing ring between back-fire relief body and the heat pipe.The radial angle of heat pipe and back-fire relief body is 90 °.Back-fire relief body top is provided with locking cap.Be provided with gland between locking cap and the back-fire relief body.Filler is housed around the heat pipe of gland bottom.The lower part of heat pipe is arranged in the silk screen, shift heat rapidly, it is radiating segment that top is stretched out spark arrester external, will shift the heat of coming in the spark arrester passage, distribute fast, the spacing in the wing footpath that the upper and lower part of heat pipe is provided with can be according to the needs adjustment of pipeline back-fire relief.Sealing ring prevents that combustion gas is revealed between heat pipe and the back-fire relief body.Locking cap is connected and fixed heat pipe and back-fire relief body, and gland below it and the filler that seals below the gland are compressed.Be connected in the pipeline after spark arrester assembled on request and get final product.Because heat pipe is to utilize the principle of phase transformation to finish heat conduction, its heat-transfer capability can be higher than the best metal number of heat conductivility with more than thousand times.The utility model dry type spark arrester is installed on pipeline that needs back-fire relief and device, and under the normal condition, heat pipe is in non-started state, and the heat conduction amount of heat pipe is very little.When detonation, tempering or string fire take place in pipeline or the device when, because temperature is higher than the start-up temperature of heat pipe, heat pipe can start immediately, to be higher than the capacity of heat transmission of good heat conductive metal (as gold, silver, copper etc.) more than thousands of times the heat of flame combustion is rejected to rapidly outside pipeline or the device.Silk screen before and after the heat pipe (also can for filler etc.) can be drawn flowing of flame heat regulating better, and heat is evenly distributed on heat pipe, the reliability and the security that further improve spark arrester.After the fray-out of flame, heat pipe also can revert to the state of low heat conduction rapidly.
The beneficial effects of the utility model are: can remedy that the combustion product heat can not pass out the outer weak point of pipeline rapidly in the existing common dry type spark arrester, back-fire relief is effective, reliability improves greatly, simple in structure, physical dimension is less, flow resistance under the low cost of manufacture, normal operation is less.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is that master of the present utility model looks sectional structural map.
Fig. 2 is that sectional structural map is looked on a left side of the present utility model.
Among the figure, 1. fin, 2. heat pipe, 3. locking cap, 4. back-fire relief body, 5. gland, 6. filler, 7. sealing ring, 8. silk screen, 9. alignment pin, 10. alignment pin.
The specific embodiment:
The dry type heat pipe spark arrester that assembles is connected on the pipeline that needs back-fire relief by alignment pin 9,10 installations, when combustible burning or detonation appear in pipeline one side, flame is by the thin channel of silk screen 8, just can extinguish or partly extinguish, the heat that burning produces then is transmitted to rapidly beyond the pipeline by heat pipe 2, can avoid the combustible Yin Gaowen of spark arrester opposite side to produce blast or burning.Temperature is reduced to below heat pipe 2 start-up temperature after the fray-out of flame, and then heat pipe 2 capacity of heat transmission descend rapidly.The start-up temperature of heat pipe 2 can be determined by selecting methods such as working medium according to concrete operating mode.
The dry type spark arrester that uses on the small diameter pipeline can only just can be finished the heat that burning is produced with the heat pipe 2 of a two ends band fin 1 and shift rapidly.The silk screen 8 of heat pipe 2 front and back can play the effect that suppresses the uniform temperature of flame in the pipeline.The position that the dry type spark arrester is installed in pipeline is not limit.
