Description

Cross-shaped fine mist fire-fighting cover system
Technical field
The present invention relates to fire-fighting domains, more particularly to a kind of cross-shaped fine mist fire-fighting cover system.
Background technique
In recent years, due to the fast development of China's economy, underground oil and gas pipeline arrangement are intricate, often due to The factors such as earth excavation or surface subsidence cause the breakage of pipeline, and the pipeline after breakage generates the quick evolution of flammable medium simultaneously Cause fire disaster, this accident happens occasionally throughout our country.It must be first according to technical requirements for these pipeline fire Fire extinguishing turns off valve, rear to excavate maintenance, and traditional extinguishing method is utilized in burning point near zone injection dry-chemical fire extinguishing Agent fire extinguishing.When having wind, a large amount of extinguishing chemicals are blown away, and blow-off velocity is slow, and waste extinguishing chemical is serious, and two can be generated after fire extinguishing Secondary pollution, and contaminated product.And existing double-layer circular fine mist fire-fighting cover system is limited by annular space, range of putting out a fire Smaller, the installation site of fighting nozzle is also required to higher precision, and lodging, shadow are otherwise easy to produce during ejecting extinguishing It rings extinguishing effect or can not implement to put out a fire.
Therefore it needs to improve the fire-fighting mode of fine mist fire-fighting cover system to solve the above problems.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of cross-shaped fine mist fire-fighting cover systems, can be fast Speed, effectively ground-to-ground the leakage combustible fire of down tube net is put out a fire.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of cross-shaped thin water is provided Mist put out a fire cover system, including by the sequentially connected high water tank of water conveyance steel tube, high-pressure fire service pump, high pressure metal hose, Water mists injection apparatus, make-up pipe, water-level gauge are equipped on high water tank, and the both ends of metal hose are equipped with high pressure resistant locking and connect Clutch;
Water mists injection apparatus include four in cross-shaped arrangement circular arc-shaped metal pipe, be installed on metal pipe end The upper reinforcement of the support lower margin, four the high pressure water uniform distributor set on four metal tube infalls, connection metal tubes of lower section The upper port of muscle, lower reinforcing rib, four metal tubes is connected to high pressure water uniform distributor, and endcapped simultaneously constitutes a concentric circles, Several downward opening mist-generating nozzles are equipped with along metal tube circumferencial direction.
In a preferred embodiment of the present invention, the material of metal tube is stainless steel, and diameter is 40-50 millimeters, and wall thickness is 4-6 millimeters, bending circular arc is 90 °, the water for the distribution of conveying high-pressure water uniform distributor.
In a preferred embodiment of the present invention, 3-4 thin water has along the circumferential direction been equidistantly spaced from every metal tube Atomizing nozzle, the water mists large area for enabling it to eject effectively cover fire extinguishing range.
Further, mist-generating nozzle is made of stainless steel, and jet angle is 120 °, and water inlet caliber is 25-32 millimeters, 5-10 centimetres are exported below the center line apart from metal tube.In implementing the present invention, it may, the inventors discovered that water mists spray When the jet angle of mouth is 120 °, the water mists ejected can form uniform moisture film and be covered on combustion flame, play quickly The effect effectively put out a fire.
In a preferred embodiment of the present invention, the material of high pressure water uniform distributor is stainless steel tube, and interior diameter is 150-200 millimeters, it is highly 400-500 millimeters that wall thickness, which is 4-6 millimeters, and lower part closing, top integral type is provided with length The stainless steel connecting tube for being 50-75 millimeters for 20 centimetres, diameter, stainless steel upper end of connecting tube install high pressure resistant locked engagement device. The water that high pressure metal hose conveying comes is buffered and is evenly distributed to four metal tubes by high pressure water uniform distributor.
In a preferred embodiment of the present invention, it is 1.5-2.5 meters that four metal pipe ends, which surround concentric diameter of a circle, To form one completely without the flash absorber at dead angle on combustion flame top.
In a preferred embodiment of the present invention, high pressure resistant locked engagement device is stainless steel fire-fighting connector, and diameter is 50-75 millimeters, wall thickness is 4-6 millimeters.The high pressure resistant locked engagement device is connected to high pressure metal hose, and it is high to be used to feed Press water.
The beneficial effects of the present invention are:
(1) blow-off velocity of cross-shaped fine mist fire-fighting cover system of the present invention is fast, fire-fighting efficiency is high, will not be right Environment generates secondary pollution;And the fire extinguishing coverage area of flash absorber can be effectively improved, meet it is quick, effectively put out tank fire Purpose and technical requirements, for exposed imflammable gas or fluid pipeline fire extinguishing after can be also used for its cooling;
(2) cross-shaped fine mist fire-fighting cover system of the present invention had both overcome traditional sprinkling dry powder fire extinguishing agent The disadvantage that fire-fighting efficiency is low, waste extinguishing chemical is serious, and overcome appearance when double-layer circular fine mist fire-fighting covers on spray fire extinguishing agent The drawbacks of easily collapsing;
(3) cross-shaped fine mist fire-fighting cover system structure of the present invention is simple, both ensure that the mesh effectively put out a fire , and reached light-weight, small in size, and it is economic and practical, it places, transformation, feature easy to maintenance.
