DETAILED DESCRIPTION

[0027] The preferred embodiments of the utility model are given below in combination with the drawings to specifically describe the technical scheme of the utility model.

[0028] Figure 1 The overall structure diagram of the utility model is shown in the figure, and the integrated high-pressure fine water mist fire extinguishing device provided by the utility model comprises: Figure 1 Water supply source 1, water storage tank 2, transfer tank 3, multiple groups of fine water mist spray heads 4, water supply pipeline 5, water storage tank to transfer tank pipeline 6, transfer tank to fine water mist spray head pipeline 7.

[0029] The water supply pipeline 5 is arranged between the water supply source 1 and the water storage tank 2, the water storage tank to transfer tank pipeline 6 is arranged between the water storage tank 2 and the transfer tank 3, and the transfer tank to fine water mist spray head pipeline 7 is arranged between the transfer tank 3 and the fine water mist spray head 4.

[0030] The water storage tank 2 comprises two groups, the water storage tank 2 is connected to the water supply source through the water supply pipeline, the water replenishing pump 8 is arranged on the pipeline between the water storage tank and the transfer tank, the water replenishing pump 8 group comprises two water replenishing pumps, one of which is used and the other is a backup, the high-pressure fine water mist pump group 9 is arranged on the transfer tank to fine water mist spray head pipeline, the high-pressure fine water mist pump group comprises multiple high-pressure fine water mist pumps, one or several of which are standby pumps, the entire integrated high-pressure fine water mist fire extinguishing device is provided with the water pump control cabinet 10, and the high-pressure fine water mist pump group and the water replenishing pump group are both connected to the water pump control cabinet 10.

[0031] The filter 11 is arranged on the transfer tank to fine water mist spray head pipeline, the transfer tank 3 is matched with the pressure stabilizing pump 20, the pressure stabilizing pump 20 is connected to the water pump control cabinet 10, and the multiple groups of fine water mist spray heads are controlled by the partition control valve 12.

[0032] The manhole 13 and the air vent 14 are arranged on the top of the water storage tank, the air vent is provided with the insect-proof cover 15, the water storage tank 2 is provided with the liquid level meter 16 on the side surface, and the transfer tank 3 is also provided with the liquid level meter 16.

[0033] The low liquid level alarm 17 and the overflow pipe 18 are further arranged on the water storage tank 2, and the water mist nozzle is provided with a nozzle anti-dripping device 19.

[0034] The joint part in the utility model can adopt flexible joint, valves can be arranged at each part of the pipeline, and the valve can adopt electric valve or manual valve, the utility model can be automatically and manually started and spray fine water mist for fire extinguishing. The utility model equipment has high integration, can reduce the designer design period, reduce the construction company installation period, can also reduce the pump house area, greatly saves the cost of the owner.

[0035] The fine water droplets are easy to vaporize after being heated, and a large amount of heat is absorbed from the surface of the burning material or the fire area during the gas-liquid phase change process, so that the surface temperature of the material is rapidly reduced, the thermal decomposition is interrupted, and the combustion is immediately terminated. The smaller the diameter of the mist droplets, the larger the surface area, and the shorter the time required for vaporization, the higher the heat absorption effect and efficiency. For the same amount of water, the surface area formed by the fine water mist droplets is at least 100 times larger than that of the water droplets sprayed by the conventional water spray nozzle (including water spray nozzle), so the cooling effect of the fine water mist fire extinguishing system is very obvious.

[0036] The mist droplets in the utility model vaporize to form water vapor 1680 times the original volume after being heated, which maximally repels the air in the fire scene, reduces the oxygen content around the burning material, and inhibits or interrupts the combustion due to lack of oxygen. The shorter the time for the water vapor formed after the system is started to completely cover the entire ignition surface, the more obvious the suffocation effect.

[0037] After the fine water mist in the utility model is sprayed into the fire scene, the water vapor formed rapidly covers the burning material, flame and smoke plume, has excellent blocking ability for the radiant heat of the flame, can effectively inhibit the ignition of other surrounding objects by radiant heat, and achieves the effect of preventing the spread of the flame.

[0038] The mist droplets with large particles and large impulse will impact the surface of the burning material, thereby wetting the burning material and preventing the solid from further volatilizing flammable gas. In addition, the system can also sufficiently wet the burning material outside the ignition position, thereby inhibiting the spread and development of the fire.

[0039] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the utility model, and various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model. These changes and improvements all fall within the scope of the claimed utility model, and the scope of protection of the utility model is defined by the appended claims and their equivalents.
