Description

Technical Field

[0001] The invention belongs to the technical field of building fire protection, and in particular relates to a fire protection separation system and method for an acrylic glass exhibition pool. Background Art

[0002] The ways of fire spread include flame contact, burning, heat conduction, heat radiation, etc. When the combustibles are arranged discretely, heat radiation is an important way to promote the spread of fire indoors and between buildings. When the fire smoke reaches a sufficient temperature, the intensity of the heat radiation it produces will ignite the surrounding combustibles, causing the fire to spread.

[0003] At present, the indoor fire fighting measures mainly include indoor fire hydrant system, automatic sprinkler system, water mist fire fighting system, foam fire fighting system, carbon dioxide fire fighting system, halogenated fire fighting system, dry powder fire fighting system, etc. For the super-large indoor ocean park equipped with a large exhibition pool, due to the need to watch marine life, the exhibition pool display window material has high requirements for light transmittance and clarity, and at the same time, it must have sufficient strength to withstand water pressure. At present, only acrylic glass can better meet the above requirements. The initial solution temperature of acrylic board is 340℃. Acrylic glass has poor performance in fire resistance integrity, thermal insulation and thermal radiation illumination. When a fire occurs indoors, the current indoor fire fighting measures cannot effectively improve the fireproof and heat insulation performance of the acrylic glass exhibition pool. Once the acrylic glass is damaged, it needs to be replaced as a whole, which is costly; and poor fireproof and heat insulation will also increase the water temperature in the pool, thereby affecting the activity of marine life in the pool.

DETAILED DESCRIPTION

[0021] The present application is further described in detail below with reference to the accompanying drawings and specific implementations:

[0022] like Figure 1-Figure 3 As shown, the fire separation system of the acrylic glass exhibition pool of the present invention includes: acrylic glass 10, a cooling water curtain system and an exhibition pool.

[0023] The exhibition pool includes a wall 11 and a water body 12 arranged inside the wall 11 , and marine life is raised in the water body 12 .

[0024] like Figure 4As shown, the wall 11 includes a concrete wall surface 14, a waterproof vapor barrier layer 15, a bonding mortar layer, a thermal insulation and fireproof layer 17, a stainless steel wire mesh 18 and a facing 19, which are arranged in sequence from the water-facing surface to the water-retaining surface. A plurality of anchor bolts 13 are also distributed on the wall 11, and the anchor bolts 13 pass through the thermal insulation and fireproof layer 17, the bonding mortar layer and the waterproof vapor barrier layer 15 in sequence and are anchored into the concrete wall surface 14. The wall 11 is provided with anchor bolts 13 at a density of not less than 4 per square. The anchor bolts 13 are screw-back heat-resistant bridge thermal insulation anchor bolts 13. The thermal insulation and fireproof layer 17 is a 70 mm thick foam glass plate with good thermal insulation and fireproof performance.

[0025] The water-facing surface of the wall 11 is the inner side of the wall 11, the end surface in contact with the water body 12, and the water-repelling surface of the wall 11 is the end surface of the wall 11 facing away from the water body 12. The water-repelling surface of the wall 11 is the fire-facing surface, and the water-facing surface of the wall 11 can also be called the fire-repelling surface.

[0026] like Figure 1 , Figure 2 As shown, a display window is provided on the wall 11, and the display window is installed with acrylic glass;

[0027] The cooling water curtain system includes a spray component and a water supply component.

[0028] The water supply assembly is arranged outside the wall 11 and is used to supply the water 12 in the exhibition pool to the spray assembly;

[0029] The spray assembly is disposed on the back water surface of the acrylic glass 10 , and the spray assembly sprays water toward the back water surface of the acrylic glass 10 to form a cooling water curtain covering the back water surface of the acrylic glass 10 .

[0030] Specifically, Figure 1 , Figure 3 As shown, the spray assembly includes a spray pipe 8 and a plurality of spray heads 9 connected to the spray pipe 8 ; the plurality of spray heads 9 are distributed above the acrylic glass 10 .

[0031] The water supply assembly includes a filter 1, a water tank 2, a water inlet pipe 5, a water outlet pipe 3, an upper limit sensor 7, a lower limit sensor 6 and a water pump 4; the water inlet pipe 5 connects the water tank 2 and the exhibition pool; the water outlet pipe 3 connects the water tank 2 and the spray pipe 8; and the water pump 4 is arranged on the water outlet pipe 3. The filter 1 is arranged at one end of the water outlet pipe 3 located in the water tank 2. The upper limit sensor 7 and the lower limit sensor 6 are arranged on the inner wall of the water tank 2 for detecting the water level. The water supply assembly may also include an alarm, which is connected to the upper limit sensor 7 and the lower limit sensor 6 by electrical signals. When the water level in the water tank 2 is lower than the setting height of the lower limit sensor 6, the alarm emits an audible and visual alarm to remind the user to supply water to the water tank 2 in time. When the water level in the water tank 2 is higher than the setting height of the upper limit sensor 7, the alarm emits an audible and visual alarm to remind the user to stop supplying water to the water tank 2. A battery electrically connected to the water pump 4 is installed on one side of the water pump 4 to facilitate power supply in a power outage state.

[0032] In some embodiments, the fire separation system further includes an automatic fire alarm system; the automatic fire alarm system is electrically connected to the cooling water curtain system through an independent line. The automatic fire alarm system may adopt an existing system, or may adopt fire detectors independently arranged around the exhibition pool, and the fire detectors are electrically connected to the cooling water curtain system. When a fire occurs, the automatic fire alarm system sends a signal to the water supply component, and the water pump 4 and the nozzle 9 start working, and a cooling water curtain is formed on the fire-facing surface of the acrylic glass 10 in time. Since the water-facing surface of the acrylic glass 10 is in direct contact with the water body 12, it can be directly protected by the water body 12.

[0033] In some embodiments, the water supply assembly further includes a filter disposed at one end of the water inlet pipe 5 extending into the exhibition pool, and the filter includes filter cotton and an electronic fish repellent hidden in the filter cotton.

[0034] In some embodiments, multiple cooling pipes are distributed in the stainless steel wire mesh 18 of the wall 11. The cooling pipes are made of copper pipes. A pressure pump is set at the end of the cooling pipes and connected to the water tank. The pressure pump is used to send water in the water tank into the cooling pipes to reduce the temperature of the fire-facing surface of the wall 11.

[0035] The working pressure of the nozzle 9 is greater than or equal to 0.12Mpa, the splash plate of the nozzle 9 is flush with the upper eaves of the acrylic glass 10, the spacing between the nozzles 9 is not greater than 2m, and the horizontal distance from the acrylic glass 10 is not greater than 0.3m, and the continuous water spraying time is not less than the fire resistance limit required by the component according to the specifications.

[0036] When the working pressure of the nozzle 9 is 0.12 MPa, the nozzle 9 can achieve a better water distribution effect, and the cooling water curtain, i.e., the water curtain, is stable and can cover the entire acrylic glass 10 , which can basically meet the cooling requirements for the acrylic glass 10 .

[0037] When the cooling water curtain system is used to cool the acrylic glass 10 for protection, the nozzle 9 will start at about 90 seconds. At this time, the temperature above the acrylic glass 10 is relatively high, the temperature of the fire-facing surface drops rapidly from 89°C to 60°C, and the temperature of the back-facing surface drops rapidly from 75°C to 56°C; the temperature in the middle and lower parts of the acrylic glass 10 is relatively low, the maximum temperature of the fire-facing surface reaches 58°C, and the maximum temperature of the back-facing surface is 54°C.

[0038] The thickness of acrylic glass 10 is 200mm~700mm. Taking the maximum heat release rate of fire as 16.9MW as an example, according to relevant data, the initial solution temperature of acrylic plate is 340℃, which is approximately equivalent to the heat flux of 10kW / m2 under the action of thermal radiation. Therefore, the maximum distance that the acrylic glass 10 can be broken by a fire with a maximum heat release rate of 16.9MW is 6.7m. The fire source is set to be 10m away from the acrylic glass 10, and the FDS model is used for simulation calculation. The maximum radiation heat intensity to which the acrylic glass 10 is subjected is 5.69kw / m2, which is less than the initial solution limit of 10kw / m2 for the acrylic glass 10.

[0039] Based on the same inventive concept, the present invention also proposes a fire prevention method for an acrylic glass 10 exhibition pool, comprising the following steps: installing a cooling water curtain system to the outside of the exhibition pool; utilizing a water supply component of the cooling water curtain system to extract water 12 in the exhibition pool and supply it to a spray component of the cooling water curtain system; utilizing the spray component to spray water onto the back water surface of the acrylic glass 10 of the exhibition pool to form a cooling water curtain covering the back water surface of the acrylic glass 10.

[0040] The above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
