During presence of fire, oil tank flame central temperature can reach 1000 to 1400 degrees Celsius, tank wall temperature can reach 500 to 700 degrees Celsius, intensity reduces, and causes tank skin to break, simultaneously time serious, its caloradiance was directly proportional to the time of presence of fire, combustion period is longer, and radiant heat density is larger, thus easily causes adjacent oil tank and other combustible combustion.Facts have proved, first with the contiguous tank of water cooling, then carrying out fire extinction by foam is again a successful fire tactics.But under normal circumstances, the oil product preignition period that catches fire is short, and burning velecity is fast, if can not put out in a short time, will bring larger difficulty along with the rising of combustion temperature to putting out a fire to save life and property of tank fire.In view of the foregoing, during fire extinguishing, before carrying out fire extinguishing dead work, organizational strength immediately should cool cupping jar and the contiguous tank that may jeopardize, to control the intensity of a fire, prevent fire spread.And due to the architectural feature of oil tank, when tissue carries out putting out a fire and cooling, after on Water spray to tank body, can be dirty fast along tank deck, major part water prolongs the splashing of tank deck edge and opens, and effectively cannot contact conduction-type cooling to the tank skin needing most cooling down, its structure urgently improves.The emergency personnel that the present inventor is fire-fighting one line, is devoted to the research of oil tank fire extinguishing cooling, has this case to produce eventually in real work.
Summary of the invention
The purpose of this utility model is the cooling structure-improved providing a kind of industrial petrol storage tank, effectively can carry out tank body cooling in oil tank routine use, in fire extinguishing, cools catch fire tank and contiguous tank body thereof fast, prevents the further expansion of the condition of a fire.
To achieve these goals, the technical solution of the utility model is as follows:
A cooling structure-improved for industrial petrol storage tank, comprises at the bottom of tank skin, tank deck, tank, and tank deck Shang You center arranges some short weather bars to surrounding, between adjacent two short weather bars and form dash raceway groove between short weather bar and tank deck.
Described short weather bar is curved, and interval is laid in tank deck different-diameter circumferentially between two.
Described short weather bar is S-shaped, and interval is laid in tank deck different-diameter circumferentially between two.
Described short weather bar linearly shape, interval is laid in tank deck different-diameter circumferentially between two.
Described short weather bar is according to the size layered arrangement of tank deck diameter at tank deck, and every layer has more than 2 short weather bars, and diameter is arranged on the interval of the short weather bar of later layer two compared with the short weather bar on small circumference.
Gap is left in junction bottom described short weather bar and tank deck.
Described short weather bar is formed with the dash ridge that several and its air spots is capable.
After adopting such scheme, the utility model oil tank, when lowering the temperature or put out a fire, because the temperature of tank deck is the highest, tank deck arranges short weather bar, owing to being short weather bar, as long as therefore short weather bar can arbitrarily arrange the effect playing dash at tank deck.Spray the effect that the water got on is subject to short weather bar, constricted flow, and in short weather bar inner accumulated, form the thin water layer of one deck, under the huge temperature difference, thin water layer or evaporation, or direct heat transfer is carried out in flowing, fast and effeciently implements cooling to tank deck.The utility model structure is simple, transforms existing equipment difficulty low, less investment, but Be very effective, can improve the effect of existing oil tank cooling fire extinguishing quickly and easily.
