Abstract
The utility model discloses a subsurface injection fire-fighting demonstration apparatus for a floating-roof oil tank. The apparatus comprises a transparent floating-roof oil tank and a transparent foam proportional mixer. A high-backpressure foam generator is arranged under the liquid level of the floating-roof oil tank. A foam outgoing terminal of the high-backpressure foam generator protrudes into the floating-roof oil tank, and a liquid incoming terminal of the high-backpressure foam generator is connected with a pipe of a liquid outgoing terminal of the foam proportional mixer. A first liquid incoming terminal of the foam proportional mixer is sequentially connected with a first water pump and a water tank by pipes, and a second liquid incoming terminal of the foam proportional mixer is sequentially connected with a foam pump and a foam liquid tank by pipes. By using the subsurface injection fire-fighting demonstration apparatus, the principles and process of subsurface injection fire-fighting operation for the floating-roof oil tank can be showed visually, and the operation can be demonstrated repeatedly.
Description
Technical field
The utility model relates to a kind of apparatus for demonstrating that pontoon-deck-tank is carried out the subsurface injection fire-fighting.
Background technology
Fire-fighting work plays very important effect to daily life and production, prevent or the generation of decrease safent accident, industrial accident, both required to have fire fighting device reliable, science, also must have and grasp the how fire fighter of proper operation of fire fighting device, the oil tank fire fighting device involves the problems such as equipment is large, flow process is complicated, fire fighter such as need are understood the fire-fighting principle, need to expend very large energy, and can not well understand operation workflow and the principle of fire fighting device, the science that is not easy to is grasped fire-fighting skill and technology.In order to allow better the fire fighter understand the fire-fighting principle, to grasp knowledge on fire fighting, just need comparatively intuitively fire demonstration device.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model provides a kind of pontoon-deck-tank subsurface injection type fire demonstration device, visual principle and the process of pontoon-deck-tank being carried out the subsurface injection fire-fighting that show, but and repetitive operation demonstration.
The technical solution of the utility model is a kind of pontoon-deck-tank subsurface injection type fire demonstration device, comprises transparent pontoon-deck-tank and transparent foam proportioner; The liquid level below of described pontoon-deck-tank is provided with the high back pressure foam producer, and the blebbing end of described high back pressure foam producer stretches in the pontoon-deck-tank, and its liquid feeding end is connected with the outlet end pipeline of described foam proportioner; The first liquid feeding end of described foam proportioner successively pipeline is connected with the first water pump, water pot; The second liquid feeding end of described foam proportioner successively pipeline is connected with foam pump, concentrated tank.
Further, described high back pressure foam producer arranges near the bottom of described pontoon-deck-tank.
Further, described water pot successively pipeline is connected with the second water pump, water spray system, and described water spray system is arranged on the outer wall top of pontoon-deck-tank.
Further, described pontoon-deck-tank periphery is provided with fending groin.
Further, the floating roof of described pontoon-deck-tank adopts polyfoam to make, and described floating roof top is provided with the ring-shaped rubber O-ring seal that is fixed in pontoon-deck-tank.
The beneficial effects of the utility model are: because pontoon-deck-tank and foam proportioner are transparent, so the fire fighter can see the mixed process of foam solution and water intuitively, and foam rises to the process that liquid level spreads covering under liquid level, thereby so that the fire fighter can understand the fire-fighting principle of fire fighting device intuitively.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of pontoon-deck-tank in the utility model.
Embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of pontoon-deck-tank subsurface injection type fire demonstration device such as Fig. 1 and shown in Figure 2, comprises transparent pontoon-deck-tank 1 and transparent foam proportioner 5; The liquid level below of described pontoon-deck-tank 1 is provided with high back pressure foam producer 4, and the blebbing end of described high back pressure foam producer 4 stretches in the pontoon-deck-tank 1, and its liquid feeding end is connected with the outlet end pipeline of described foam proportioner 5; The first liquid feeding end of described foam proportioner 5 successively pipeline is connected with the first water pump 8, water pot 9; The second liquid feeding end of described foam proportioner 5 successively pipeline is connected with foam pump 6, concentrated tank 10.
Further, described high back pressure foam producer 4 arranges near the bottom of described pontoon-deck-tank 1.The foam pressure that high back pressure foam producer 4 produces is higher, can rise on the liquid level and at liquid level from pontoon-deck-tank 1 bottom fast and spread, and covers whole liquid level, demonstrates out the fire extinguishing procedure to pontoon-deck-tank.
Further, described water pot 9 successively pipeline is connected with the second water pump 7, water spray system 2, and described water spray system 2 is arranged on the outer wall top of pontoon-deck-tank 1.Realize the analog demenstration of the complete rear spraying cooling process to pontoon-deck-tank 1 of fire extinguishing.
Further, described pontoon-deck-tank 1 periphery is provided with fending groin 3.Fending groin 3 can stop the current that flow down along pontoon-deck-tank 1 outer wall in the spraying cooling process to be stretched everywhere, is beneficial to keep the clean and tidy of environment.
Further, the floating roof 11 of described pontoon-deck-tank 1 adopts polyfoam to make, and described floating roof 11 tops are provided with the ring-shaped rubber O-ring seal 12 that is fixed in pontoon-deck-tank 1.Floating roof 11 quality that polyfoam is made gently can rise, descend with liquid level, and ring-shaped rubber O-ring seal 12 prevents the leak of liquid in the pontoon-deck-tank 1.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
