Background technology
Along with the continuous growth of demand for energy, quantity and the volume of oil tank increase gradually.Once oil tank breaking out of fire, will cause great property loss and casualties.Oil tank initial fire disaster is carried out Rapid Alarm and puted out a fire to save life and property, prevent that it is evolved into great fire incident, has far-reaching and real meaning.
At present, oil tank froth fire extinguishing system adopts total flood fire suppression mode mostly.Do not consider fire location and fire area, all foam maker starts and sprays simultaneously, and the annular space of foam between floating plate top slice and weather shield collects.When foam covers annular space completely and is pooled to certain height, could flow in sealing ring and put out a fire from fire location breach.This fire-fighting mode response speed is slow, attack time long, foam consumption is large.
In recent years, the CFI gas extinguishing system of the TANK GUARD froth fire extinguishing system of various new fire extinguishing system ,Ru Dubai Universal Tech. Corp. exploitation, the exploitation of Dutch SAVAL company and Foam Fatale Technology froth fire extinguishing system etc. have been there are abroad.These systems have advantages of start fast, efficiency is high, be easy to safeguard, but mostly only limits to the small size tank fire of putting out a fire to save life and property, flow and pressure all cannot meet put out a fire to save life and property in, the demand of large oil tank fire.And this class fire-fighting system mostly needs original fire-fighting system and storage tank to change on a large scale, and it is higher that technology realizes cost.
Summary of the invention
In order to solve the problem of mentioning in background technology, the invention provides a kind ofly when oil tank breaking out of fire, can carry out Rapid Alarm and the fire extinguishing system of putting out a fire to save life and property to oil tank fire location.The present invention is achieved by the following scheme:
A kind of tank fire is reported to the police and fire extinguishing system, comprise foam weir plate, tank skin, fiber grating warning system, coupled control table, magnetic valve, apparatus for spray of foam, fire foam, annular space between foam weir plate and tank skin is divided into several regions, independently report to the police in fiber grating warning system subregion, alarm signal is sent to coupled control table, coupled control table is sent to alarm signal the magnetic valve of corresponding region, the apparatus for spray of foam of solenoid control signal designation corresponding region starts automatically, and spray foam extinguishing chemical is put out a fire.
Annular space between described foam weir plate and tank skin is divided with foam baffle, and foam baffle stretches into below the pasta in oil tank, leaves gap with tank skin.
Described foam baffle adopts fire resistant flexible material.
Fiber grating warning system carries out parallelly independently patrolling and examining to the signal of each subregion, realizes subregion and independently reports to the police, the fire extinguishing of fixed point spray foam.
Annular space between foam weir plate and tank skin is carried out to region division, in conjunction with fiber grating warning system and froth fire extinguishing system, realize subregion interlock and control, fire is fixed a point to report to the police and subregion fire extinguishing.
Annular space between foam weir plate and tank skin is installed foam baffle, and foam baffle stretches into below pasta through secondary sealer, has realized the division of foam build-up areas, can save foam and improve fire-fighting efficiency.
Fiber grating warning system carries out parallelly independently patrolling and examining to the signal of each subregion, refer to that fiber grating warning system is to each subregion alarm signal independence self check, do not interfere with each other, by subregion arrange, the mode of parallel transmission signal overcome the complementary defect in tandem single cycle type of alarm Xia Ge region, realized subregion and independently reported to the police.
Utilize automatic control technology to realize slitless connection and the coordination and response of fiber grating warning system and froth fire extinguishing system, can realize the subregion of foam maker and control.
The present invention has the following advantages: (1) fire alarm system fast response time, alert locations precision are high; (2) interlock that has realized fiber grating warning system and froth fire extinguishing system is controlled, and froth fire extinguishing system can realize subregion fixed point and spray, and can put out rapidly, exactly oil tank initial fire disaster; (3) by theory, calculate and experiment test shows, the present invention can save foam more than 50% and fire-fighting efficiency raising; (4) on the basis of existing fire extinguishing system, without change on a large scale, both can realize the present invention, it is lower that technology realizes cost, and feasibility is high.
The present invention can be controlled at tank fire the initial stage on fire, reaches the effect of quick response, interlock control, subregion fire extinguishing, realizes the object of putting out fast tank fire.
