Abstract
A water-spraying apparatus for extinguishing fire and cooling oil tank is composed of a water-supplying pipe, an annular pipe arranged on the top of external surface of oil tank and connected to said water supplying pipe, multiple nozzles on said annular pipe, multiple centrifugal water sprayers, and fire accident detectors.
Description
Technical field
The present invention relates to a kind of fire plant, particularly a kind of fire-equipment water jetting cooler of oil tank.It is suitable for water spray cooling and the fire prevention cooling and the blocking-up on oil tank surface, can be installed in widely on the oil tank of large, medium and small type.
Background technology
The oil storage tank of existing oil plant and oil reservoir area, they mostly are columniform exposed vertical filling bodies, also have horizontal, all be to store inflammable, explosive liquid fuel in jar, and the population density of oil tank is big, does not establish automatic sprinkler fire extinguishing system, in case so oil reservoir area breaking out of fire, will spread and bring disaster to contiguous oil tank, and the volatile loss of oil plant in the oil tank under high temperature Exposure to Sunlight condition, cause the wasting of resources and increase the fire odds.
Summary of the invention
The object of the present invention is to provide a kind of " fire-equipment water jetting cooler of oil tank " of forming by endless tube, endless tube nozzle, centrifugal energy nozzle, fire detector etc., when the breaking out of fire of oil gas jar or be subjected to the blast of contiguous burning things which may cause a fire disaster, when heat radiation jeopardizes, tank fire detector and infrared measurement of temperature can send alarm signal, the control fire pump starts fetches water in water supply line simultaneously, from endless tube nozzle and centrifugal energy nozzle ejection, and outside tank body, formed tank skin water curtain and peripheral annular water band, make oil tank obtain effectively cooling to be difficult for igniting and heat fires fried.
The objective of the invention is to be achieved through the following technical solutions:
Oil gas jar fire-equipment water jetting cooler is made up of endless tube, endless tube nozzle, centrifugal energy nozzle, fire detector, water supply line, outer setting has an endless tube in the top of oil tank wall, this endless tube is communicated with water supply line, its level of the inboard of endless tube is provided with several endless tube nozzles to upper/lower positions, this endless tube nozzle is apart from tank skin 50-500 millimeter, lay around the tank skin curved surface in the form of a ring, outside endless tube, be provided with a plurality of centrifugal energy nozzles in addition, described fire-equipment water jetting cooler of oil tank, be controlled by fire detector, and link with manual operation.
The water that equipment water jetting cooler endless tube nozzle penetrates is connected with tank skin, and connects into the water curtain that hangs on the tank skin curved surface.
In the middle of increasing endless tube during the tank skin height of equipment water jetting cooler oil tank 〉=20m and being distributed in.
Advantage of the present invention and effect are:
This equipment water jetting cooler adopts endless tube to be laid in the oil tank top, the endless tube nozzle forms the water curtain that hangs that cools to the tank skin water spray, the periphery utilizes centrifugal energy nozzle to spray big raindrop, the fire detector early warning is arranged in addition and control spray cooling, have video monitoring, picture imaging can implement remote manual water spray again, it is big that this device has a monitoring range, and cost is low, characteristics easy for installation are applicable to large, medium and small oil tank.

1 tank deck, 2 tank skins, 3 endless tubes, 4 centrifugal energy nozzles, 5 hang water curtain, 6 fire detectors, 7 monitoring spaces, 8 water supply lines, 9 annular water bands, 10 endless tube nozzles, 11 electrically-controlled valve, 12 Fire Control Cabinet, 13 fire pumps, 14 fire cisterns.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1,2,5, the water supply part of this fire-equipment water jetting cooler of oil tank is installed in around tank deck (1) portion of oil tank, its endless tube (3) is connected with water supply line (8), endless tube (3) is provided with several endless tube nozzles (10), also is connected with the centrifugal energy nozzle (4) that its periphery be arranged in parallel in addition, and the water supply line of front end (8) is connected with electrically-controlled valve (11) and fire pump (13), fire cistern (14) and Fire Control Cabinet (12).
Automatically controlled part; Fire detector (6), camera around the oil tank are connected with bus, and bus is connected with Fire Control Cabinet (12) with control room bus cabinet." fire-equipment water jetting cooler of oil tank " can be changed with manual operation automatically with automatically controlled fire detector (6), video imaging, picture cutting, visual carrying out.
Below detailed its course of work of elaboration: at first whole system is under the normal monitor state in real time, suddenly audible-visual annunciator sends alarm signal in the oil tank fire protection control room, image splitter cuts to the oil tank image of breaking out of fire on the picture simultaneously, the operator on duty has seen on-the-spot fire clearly, the visual determination that through 10s people is, affirmation has fire to take place in monitoring space (7), at this moment fire pump (13) starts, to water supply line (8) inner water-supply, electrically-controlled valve (11) is opened, water enters fills the back from endless tube nozzle (10) in the endless tube (3), ejection in the centrifugal energy nozzle (4), Fig. 5 is the system diagram of fire-equipment water jetting cooler of oil tank.
Can be observed the situation of endless tube nozzle (10) referring to Fig. 3,4 to the cooling of tank skin (2) water spray, in order to prevent that oil tank is subjected to behind the high temperature a jar internal combustion fry dried food ingredients and gives birth to thermal expansion, explosive evaporation, under the inboard level of endless tube (3) miter angle, endless tube nozzle (10) is set, the current of each endless tube nozzle (10) all are miter angle and go to tank skin (2) spray, water column is subjected to the effect of tank skin (2) and curved surface between its two nozzle, has formed the water curtain that hangs (5) of 2.5 millimeters thick on the surface of tank skin (2).
Nozzle bore sectional area: 2-50mm
2/ m;
System works pressure: 0.05Mpa;
Water cooling intensity: 2.5L/min.m
2
The water of endless tube nozzle (10) ejection simultaneously almost; tank skin (2) side face is cooled; the tank body side face is all adsorbing the water curtain that hangs (5) from top to bottom; on the whole like having put on the water skirt to oil tank; the big raindrop that spray at peripheral centrifugal energy nozzle (4) have formed the back-fire relief waterwall one; play fire prevention, control fire, cooling effect effectively, make oil tank obtain protection, be difficult for generation heat and fire fried.
In a single day trend out of control, that enlarge and stretch takes place in the oil tank of breaking out of fire in the reservoir area, the night shift room operating personnel can show according to the picture of image splitter, the oil tank image of breaking out of fire region adjacent is cut on the picture, operates electrically-controlled valve (11) and open, cool to being sprayed water, prevent to form chain reaction after the oil tank breaking out of fire by the oil tank that jeopardized.
This system also has the in-house operation function.Index according to summer temperature and Exposure to Sunlight, can implement rain making at any time, to cooling that each oil tank carries out taking turns, contain the evaporation of fluid oil as much as possible, can reduce waste, the increase income of resource, the concentration of fuel gas reduces the pollution of environment and atmosphere in the control oil depot district air, reduces the fire odds.
