Abstract
The utility model relates to a large-sized storage tank perpendicular foam distributor, which comprises a storage tank provided with a fire fighting foam inlet tube. A perpendicular foam distributor is mounted in the storage tank and consists of an upper end cap, a perpendicular distribution tube and a base, a foam inlet hole is arranged at the top of the perpendicular distribution tube and connected with the fire fighting foam inlet tube of the storage tank, and the perpendicular distribution tube is connected with the storage tank via a fixing support and provided with foam spraying notches. By the aid of the design of the perpendicular distribution tube and the foam spraying notches, the large-sized storage tank perpendicular foam distributor can lead fire fighting foam to be sprayed out from the foam spraying notch which is closest to the liquid surface, can separate air from the liquid level of combustible media, and achieves the purpose of fire extinguishment.
Description
Technical field
The utility model relates to a kind of fire plant of large-scale storage tank, specifically relates to the vertical foam sparger of a kind of large-scale storage tank.
Background technology
The large-scale storage tank of storing inflammable medium all need be provided with the fire-fighting foams inlet on tank skin top, as the presence of fire accident, thereby the fire-fighting foams mouth sprays into foam inflammable medium and air is cut off the fire prevention fire extinguishing effect of playing that reaches.
Traditional fire-fighting foams mouth is arranged on the above position of the highest storage liquid level of tank wall, and when fire-fighting needed, foam was sprayed by the fire-fighting foams mouth.The medium storage capacity more after a little while in jar, the medium liquid level is in than low level, this moment, jar interior gas-phase space was relatively large, in case presence of fire, need just can make medium and air insulated from the tank body top a large amount of foam of ejection, and need the long time fire suppression easily could be caused great chemical industry safety misadventure.
The utility model content
At the deficiency that storage tank design for fire protection in the prior art exists, the purpose of this utility model is to provide a kind of large-scale storage tank vertical foam sparger, only needs a spot of fire-fighting foams can reach the purpose of fire extinguishing fast.
The technical scheme that the utility model adopted is:
The vertical foam sparger of large-scale storage tank, comprise the storage tank that is provided with the fire-fighting foams inlet pipe, its inside is equipped with vertical foam sparger, vertical foam sparger is made of upper end cover, vertical distribution pipe and base, vertical distribution pipe top has the foam ingate, the foam ingate is connected with the fire-fighting foams inlet pipe of storage tank, and the vertical distribution pipe is connected with storage tank by fixed support, has spray foam notch on the vertical distribution pipe.
Compare with storage tank fire plant of the prior art, advantage of the present utility model is,
Design by vertical distribution pipe and spray foam notch can make fire-fighting foams from spraying from the nearest spray foam notch of liquid level, can separate air and inflammable medium liquid level soon, reaches the purpose of fire extinguishing, need not to spend the plenty of time to spray a large amount of foams.
Description of drawings
Fig. 1 is the structural representation of the vertical foam sparger of the utility model large-scale storage tank.
Fig. 2 is another angle structural representation of the vertical foam sparger of the utility model large-scale storage tank.
In Fig. 1～2,1-storage tank, 2-fire-fighting foams inlet pipe, 3-upper end cover, 4-foam ingate, 5-vertical distribution pipe, 6-base, 7-fixed support, 8-spray foam notch, liquid level in the 9-groove.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that utility model is further described below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, storage tank 1 is provided with fire-fighting foams inlet pipe 2, and inside is equipped with vertical foam sparger, and vertical foam sparger is made of upper end cover 3, vertical distribution pipe 5 and base 6, and is connected with storage tank 1 by fixed support 7.
Vertical distribution pipe 5 tops have foam ingate 4, and foam ingate 4 is connected with the fire-fighting foams inlet pipe 2 of storage tank 1, and every interval one end distance leaves and establishes a spray foam notch 8 on the vertical distribution pipe 5.
When liquid level 9 is low in groove, the lower end of vertical distribution pipe is immersed in the liquid dielectric, during presence of fire, enter in the vertical distribution pipe by the fire-fighting foams inlet pipe, a large amount of fire-fighting foams is spraying in the lower spray foam notch of liquid level rapidly, air and inflammable medium liquid level are separated, reach the purpose of fire extinguishing.
