Abstract
The invention relates to an automatic fire extinguishing method for a suspended type storage tank, and mainly solves the problems that in the prior art, a fire extinguishing system is slow in response and extra power is needed. The automatic fire extinguishing method well solves the problems by adopting the technical scheme that an extinguishant carrier 2 is arranged above a storage tank, the extinguishant carrier 2 is filled with an extinguishant 3, and the extinguishant carrier 2 is made from a material which is easy to melt in fire; when a fire happens to the storage tank, the extinguishant carrier 2 is molten, and then the extinguishant 3 falls to a fire point to extinguish the fire in time under the action of gravity. The method can be applied to fire extinguishment of the storage tank.
Description
Technical field
The present invention relates to a kind of hanging type storage tank self-extinguishing method.
Technical background
Storage tank is one of common equipment of oil, petrochemical industry, chemical industry, Coal Chemical Industry industry, for storing liquid material.When storing when flammable liquid, because the reason such as poorly sealed causes flammable liquid or inflammable gas to leak, may cause storage tank fire after meeting the incendiary sources such as static or thunderbolt.According to case in the past, if just put out a fire immediately at the storage tank initial stage of catching fire, fire extinguishing success rate is higher, and if storage tank fire has developed into more serious degree, because inventory in storage tank is larger, be difficult to successfully put out a fire to save life and property.
In CN2605885, relate to a kind of foam-water spraying coupling extinguishing device, comprise sealed sprinkler head with temperature sensor, connect feed pipe and the foam liquid tank of sealed sprinkler head by pipeline.In described feed pipe, be serially connected with wet alarm valve and foam proportioner.One outlet of described wet alarm valve is by the pressure switch in delayer pressure relief pipe taking alarm; be connected in control piper by the Pressure Relief Valve of this pressure switch control; the controlled termination control piper of foam solution control valve in foam liquid tank exit; the outlet of foam solution control valve connects foam proportioner; be applicable to install in the building and structures that have flammable liquid existence of sprinkler protection system; but this device needs extra power, reaction has hysteresis.
All there is fire extinguishing system response lag, need the problem of extra power in prior art.
Summary of the invention
Technical problem to be solved by this invention is fire extinguishing system response lag in prior art, needs the problem of extra power, and a kind of new hanging type storage tank self-extinguishing method is provided.The method, for storage tank fire extinguishing, has advantages of and is swift in response, does not need extra power.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of hanging type storage tank self-extinguishing method, extinguishing chemical supporting body 2 is set above storage tank 1, in extinguishing chemical supporting body 2, be mounted with extinguishing chemical 3, extinguishing chemical supporting body 2 adopts meets easily thawing material of fire, in the time of storage tank breaking out of fire, extinguishing chemical supporting body 2 melts, and extinguishing chemical 3 jumps on point of origin fire extinguishing in time by Action of Gravity Field.
In technique scheme, preferably, described extinguishing chemical supporting body 2 covers storage tank 1 top area or easy breaking out of fire region.
In technique scheme, preferably, described extinguishing chemical 3 is solid or liquid extinguisher, for the material storing in storage tank, selects the extinguishing chemical adapting.
In technique scheme, preferably, described extinguishing chemical supporting body 2 adopts highstrenghtpiston's film material.
In technique scheme, preferably, extinguishing chemical supporting body 2 is with the nearly subsides of storage tank 1 top area or easy breaking out of fire region or retain the distance of 1-100 centimetre.
In the present invention, meet due to extinguishing chemical is placed in the extinguishing chemical supporting body that fire easily melts, in the time of storage tank breaking out of fire, supporting body melts, and extinguishing chemical jumps on point of origin in time by Action of Gravity Field completely, is swift in response, and does not need other extra power sources, and reliability is high.Supporting body also can be storage tank sunshade rain-proof, prevents that summer tank temperature is too high, also can prevent the storage tank corrosion that drenched with rain, and has obtained good technique effect.
