Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguishing systems, and particularly to a fine water mist fire extinguishing system applied to high-rise buildings and an operation method thereof. Background Art

[0002] At present, the traditional fire extinguishing technologies adopted by high-rise buildings mainly include several main types such as indoor fire hydrant fire extinguishing systems and gas fire extinguishing systems. However, the design and application of these fire extinguishing systems all have certain limitations and are difficult to fully meet the rapidly changing requirements of the current building forms. Specifically, the indoor fire hydrant fire extinguishing system relies on personnel to enter the fire scene for operation, and the process is relatively complex and cumbersome; although the gas fire extinguishing system has high fire extinguishing efficiency, it has strict requirements on the airtightness of the protected space, there is a risk of leakage, and a single injection often fails to completely solve the problem of re-ignition, and the later maintenance cost is also relatively high.

[0003] Therefore, the use of water fire extinguishing technology has its unique fire extinguishing advantages. However, water resources, as precious natural resources, have limited regeneration ability. Considering that a complete fire extinguishing system needs to reserve a large amount of water resources, this undoubtedly further exacerbates the problem of water resource occupation, and at the same time puts forward higher requirements for building space resources. With the rapid increase in the number of high-rise buildings and the continuous rise in building height, the automatic sprinkler fire extinguishing system is limited because it consumes a large amount of water resources and occupies a large amount of building space resources, and is prone to serious water damage during the fire extinguishing process. Therefore, it is particularly urgent to require an economical, efficient and reasonable fire extinguishing system to optimize the traditional fire extinguishing technology. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to solve the technical problems of excessive water resource consumption, inefficient fire extinguishing mode and serious water damage during fire extinguishing in the prior art. The present invention provides a fine water mist fire extinguishing system applied to high-rise buildings and an operation method thereof, which has the effects of economical and efficient fire extinguishing.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a fine water mist fire extinguishing system applied to high-rise buildings, which includes: a fine water mist fire extinguishing device and a digital control device for controlling the fine water mist fire extinguishing device.

[0006] The fine water mist fire extinguishing device includes: a water supply component and a water supply pipe network. The water supply pipe network includes a first main pipe, a second main pipe and a plurality of floor pipes. Both the first main pipe and the second main pipe are communicated with the water supply component. The plurality of floor pipes are arranged in parallel and distributed on each floor of the building. One end of each floor pipe is connected to the first main pipe through a floor valve, and the other end of each floor pipe is connected to the second main pipe. A plurality of parallel regional pipes are communicated on each floor pipe, and a regional fire extinguishing unit is arranged on each regional pipe.

[0007] The digital control device includes a monitoring module, a data integration and processing module, and a response control module. The monitoring module is arranged near each area fire extinguishing unit and is used to monitor the fire situation in this area and send the monitoring data to the data integration and processing module. The data integration and processing module generates corresponding response results according to the monitoring data and sends them to the response control module. The response control module controls the water mist fire extinguishing device to make a fire extinguishing response according to the response results;

[0008] Among them, the data integration and processing module classifies the fire into a first-level fire, a second-level fire or a third-level fire. A first-level fire means that the monitoring module in any area monitors a fire, and the corresponding first-level response result is that the response control module controls the area fire extinguishing unit in this area to start. A second-level fire means that all monitoring modules on any floor monitor a fire, and the corresponding second-level response result is that the response control module controls the floor valve and all area fire extinguishing units on this floor to start.

The specific technical effects are as follows: By using the monitoring module to monitor the fire situation in each area in real time, the fire source can be quickly discovered and located, realizing early warning. The data integration and processing module quickly classifies the fire level according to the monitoring data and triggers the corresponding response control module to ensure that the water mist fire extinguishing device can make a fire extinguishing response and effectively contain the spread of the fire; Compared with the traditional water spray system, the water mist fire extinguishing system can greatly reduce the consumption of water resources. At the same time, through the layered and zoned pipeline layout and the setting of area fire extinguishing units, this system can only carry out fire extinguishing operations on the affected areas during a fire, avoiding mis-spraying on the unaffected areas, further improving the utilization efficiency of water resources and reducing the occupation of building resources; According to different fire levels, this system can adjust the fire extinguishing strategy. In the case of a first-level fire, only the area fire extinguishing unit in the affected area is started to achieve local and rapid fire extinguishing; In the case of second-level and third-level fires, it is expanded to start all area fire extinguishing units on the entire floor and adjacent floors respectively to ensure that the fire is effectively controlled while avoiding unnecessary waste of fire extinguishing resources; Through the application of the digital control device, the operation of the fire extinguishing system is made more intelligent and automated, reducing the need for manual intervention and improving the efficiency and safety of fire extinguishing operations; Through the recording and analysis functions of the data integration and processing module, it can also provide data support for subsequent fire prevention and emergency handling.

[0009] Further, the area fire extinguishing unit includes an area valve and a number of fine water mist nozzles. The number of the fine water mist nozzles are all connected to the area valve, the area valve is connected to the area pipeline, and the area valve is connected to the response control module through a control circuit. The specific technical effect is: It can extinguish fires targeted at the specific location where the fire occurs, reduce the waste of water resources, and improve the fire extinguishing efficiency.

[0010] Further, the fine water mist nozzle is an impact type fine water mist nozzle. The specific technical effect is: The impact type fine water mist nozzle is suitable for extinguishing fires in large spaces, has a simple structure and is convenient for maintenance, consumes relatively less water resources during the fire extinguishing process, and no residues will be left after the fine water mist evaporates.

[0011] Further, the fine water mist nozzle is a centrifugal type fine water mist nozzle. The specific technical effect is: The centrifugal type fine water mist nozzle is suitable for high-precision fire extinguishing, can quickly play the role of adsorbing and purifying the smoke by the fine water mist, and is applied to key areas for personnel evacuation such as corridors and stairwells, thereby providing a safer evacuation passage for the escaping personnel.

[0012] Further, the water supply component includes: a water tank and at least one set of water pump groups. The water tank is connected to the water pump groups, the first main pipeline and the second main pipeline are both connected to the water pump groups, and the water pump groups are connected to the response control module through a control circuit.

[0013] Further, the water pump group includes a number of high-pressure water pumps with the same power. Each high-pressure water pump is connected to the water tank. The specific technical effect is: It can meet the fire extinguishing requirements of high-rise buildings.

[0014] Further, the monitoring module includes a temperature sensor and a smoke detector. The temperature sensor and the smoke detector are both connected to the data integration and processing module through a control circuit.

[0015] Further, the digital control device further includes: an alarm device. The alarm device is connected to the response control module through a control circuit.

[0017] An operation method of a fine water mist fire extinguishing system applied to high-rise buildings as described in any one of the above, wherein, it includes the following steps:

[0018] Step S1, once the monitoring module detects a fire, it sends the monitoring data to the data integration and processing module;

[0019] Step S2, the data integration processing module analyzes the monitoring data, and the data integration processing module divides the fire into a first-level fire, a second-level fire or a third-level fire. A first-level fire is a fire detected by a monitoring module in any area, and the monitoring modules in the area transmit the monitoring data to the data integration processing module through a control circuit. A second-level fire is a fire detected by all monitoring modules on any floor, and all monitoring modules on the floor transmit the monitoring data to the data integration processing module through a control circuit. A third-level fire is a fire detected by all monitoring modules on any floor and the upper and lower floors adjacent to the floor, and all monitoring modules on the affected floor and the upper and lower floors adjacent to the affected floor transmit the monitoring data to the data integration processing module through a control circuit.

The first-level response result is that the response control module controls the water pump group to deliver water to the water supply network and controls the regional fire extinguishing unit of the disaster area to open. The water passes through the water tank, the water pump group, and the second main pipeline in sequence and then flows out from the regional fire extinguishing unit of the disaster area.

[0022] Step S5: After the fire is extinguished, the control module controls the water pump group, the regional fire extinguishing unit and / or the floor valve to be closed according to the preset program response.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The present invention uses a monitoring module to monitor the fire situation in each area in real time, which can quickly discover and locate the fire source and achieve early warning. The data integration processing module quickly classifies the fire level according to the monitoring data and triggers the corresponding response control module to ensure that the fine water mist fire extinguishing device can respond to the fire and effectively curb the spread of the fire.

[0025] (2) Compared with the traditional water spray system, the fine water mist fire extinguishing system of the present invention can greatly reduce the consumption of water resources. At the same time, through the hierarchical and zonal pipeline layout and the setting of the regional fire extinguishing units, the system can only carry out fire extinguishing operations on the affected areas during a fire, avoiding mis-spraying on the unaffected areas, further improving the utilization efficiency of water resources, and reducing the occupation of building resources;

[0026] (3) According to different fire levels, the present invention can adjust the fire extinguishing strategy. During a Class I fire, only the regional fire extinguishing units in the affected areas are activated to achieve local and rapid fire extinguishing; during Class II and Class III fires, the activation is extended to all regional fire extinguishing units on the entire floor and adjacent floors respectively to ensure effective control of the fire, while avoiding unnecessary waste of fire extinguishing resources;

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0039] As Figures 1 to 5 shown, it is the optimal embodiment of the present invention. A fine water mist fire extinguishing system for high-rise buildings and its operation method in this embodiment include: a fine water mist fire extinguishing device 1 and a digital control device 2 for controlling the fine water mist fire extinguishing device 1.

[0040] The fine water mist fire extinguishing device 1 includes: a water supply component and a water supply pipe network 103. The water supply pipe network 103 includes a first main pipe 1031, a second main pipe 1032 and a number of floor pipes 1033. Both the first main pipe 1031 and the second main pipe 1032 are connected to the water supply component. The number of floor pipes 1033 are arranged in parallel and distributed on each floor of the building. One end of each floor pipe 1033 is connected to the first main pipe 1031 through a floor valve 104, and the other end of each floor pipe 1033 is connected to the second main pipe 1032. A number of parallel area pipes 1034 are connected to each floor pipe 1033, and an area fire extinguishing unit is provided on each area pipe 1034. Specifically, the first main pipe 1031, the second main pipe 1032 and the number of floor pipes 1033 are all made of stainless steel pipes;

[0041] The digital control device 2 includes: a monitoring module 201, a data integration and processing module 202 and a response control module 203. The monitoring module 201 is arranged near each area fire extinguishing unit and is used to monitor the fire situation in that area and send the monitoring data to the data integration and processing module 202. The data integration and processing module 202 generates a corresponding response result according to the monitoring data and sends it to the response control module 203. The response control module 203 controls the fine water mist fire extinguishing device 1 to make a fire extinguishing response according to the response result;

[0042] Among them, the data integration processing module 202 classifies a fire into a first-level fire, a second-level fire, or a third-level fire. A first-level fire means that the monitoring module 201 in any area detects a fire, and the corresponding first-level response result is that the response control module 203 controls the area fire extinguishing unit in that area to turn on. A second-level fire means that all the monitoring modules 201 on any floor detect a fire, and the corresponding second-level response result is that the response control module 203 controls the floor valve 104 and all the area fire extinguishing units on that floor to turn on. A third-level fire means that all the monitoring modules 201 on any floor and the upper and lower floors adjacent to that floor detect a fire, and the corresponding third-level response result is that the response control module 203 controls the floor valves 104 and all the area fire extinguishing units on that floor and the upper and lower floors adjacent to that floor to turn on. Thus: By the real-time monitoring of the fire situation in each area by the monitoring module 201, the fire source can be quickly discovered and located, achieving early warning. The data integration processing module 202 quickly classifies the fire level according to the monitoring data and triggers the corresponding response control module 203 to ensure that the fine water mist fire extinguishing device 1 can make a fire extinguishing response and effectively contain the spread of the fire; Compared with the traditional water spray system, the fine water mist fire extinguishing system can greatly reduce the consumption of water resources. At the same time, through the layered and zoned pipeline layout and the setting of area fire extinguishing units, this system can only carry out fire extinguishing operations on the affected areas during a fire, avoiding mis-spraying on the unaffected areas, further improving the utilization efficiency of water resources and reducing the occupation of building resources; According to the different fire levels, the fine water mist fire extinguishing level is divided into three layers to enhance the fire extinguishing accuracy and efficiency. This system can adjust the fire extinguishing strategy. In the case of a first-level fire, only the area fire extinguishing unit in the affected area is started to achieve local and rapid fire extinguishing; In the case of second-level and third-level fires, it is expanded to start all the area fire extinguishing units on the entire floor and the adjacent floors respectively to ensure that the fire is effectively controlled, while avoiding unnecessary waste of fire extinguishing resources; The application of the digital control device 2 makes the operation of the fire extinguishing system more intelligent and automated, reduces the need for manual intervention, and improves the efficiency and safety of fire extinguishing operations; Through the recording and analysis functions of the data integration processing module 202, it can also provide data support for subsequent fire prevention and emergency handling.

[0043] In this embodiment, the area fire extinguishing unit includes an area valve 105 and a number of water mist nozzles 106. The number of water mist nozzles 106 are all connected to the area valve 105, and the area valve 105 is connected to the area pipeline 1034. The area valve 105 is connected to the response control module 203 through a control circuit. Thus: The floor valve 104 and the area valve 105 are used as double valves for positioning fire extinguishing in a specific area, preventing mis-spraying, enabling targeted fire extinguishing according to the specific location of the fire, reducing waste of water resources, and improving the fire extinguishing efficiency. Specifically, the number and installation positions of the water mist nozzles 106 set in each area can be adjusted according to the function of this area inside the building. In key areas (such as areas prone to fire like the power distribution room, etc.), the water mist nozzles 106 can be arranged in a denser pattern.

[0044] Preferably, the area valve 105 is installed on the area pipeline 1034 by means of flange or welding to ensure firm connection and sealing.

[0045] In this embodiment, the water mist nozzle 106 is an impact type water mist nozzle 106. Thus: The impact type water mist nozzle 106 is suitable for fire extinguishing in large spaces. The impact type water mist nozzle 106 can be set in major functional areas of the building (such as: office areas, public areas, etc.), and has a simple structure and is convenient for maintenance. It consumes relatively less water resources during the fire extinguishing process, and there will be no residue left after the water mist evaporates.

[0046] In this embodiment, the water mist nozzle 106 is a centrifugal type water mist nozzle 106. Thus: The centrifugal type water mist nozzle 106 is suitable for high-precision fire extinguishing. The centrifugal type water mist nozzle 106 can be set in the escape passage areas inside the building (such as: corridor areas, stairwell areas, etc.), and can quickly play the role of adsorbing and purifying the smoke by the water mist. Applied in key areas for personnel evacuation such as corridors and stairwells, it can provide a safer escape passage for the escaping personnel.

[0047] In this embodiment, the water supply component includes: a water tank 101 and at least one set of water pump groups 102. The water tank 101 is connected to the water pump groups 102. The first main pipeline 1031 and the second main pipeline 1032 are both connected to the water pump groups 102. The water pump groups 102 are connected to the response control module 203 through a control circuit. Specifically, the number of water pump groups 102 is set according to the requirements that can meet the building fire extinguishing code, which can effectively guarantee the power requirements for fire extinguishing in each protected area.

[0048] Preferably, a control valve 107 is provided between the water tank 101 and the water pump groups 102 for water discharge operation. The control valve 107 is connected to the response control module 203 through a control circuit.

[0049] In this embodiment, the water pump group 102 includes a plurality of high-pressure water pumps with the same power, and each high-pressure water pump is connected to the water tank 101. Thus, the fire extinguishing requirements of high-rise buildings are met. Specifically, for example, the design power range of the water pump group 102 for a small high-rise building with 10 to 20 floors is 1.5KW to 5.5KW, and the design power range of the water pump group 102 for a medium-sized high-rise building with 20 to 30 floors is 5.5KW to 15KW.

[0050] In this embodiment, the monitoring module 201 includes a temperature detector and a smoke detector, and both the temperature detector and the smoke detector are connected to the data integration processing module 202 through a control circuit.

[0051] In this embodiment, the digital control device 2 further includes: an alarm device 204 , which is connected to the response control module 203 via a control circuit.

[0052] In this embodiment, the response control module 203 is a PC computer. Therefore, the PC computer has a high-speed processor and a large-capacity memory, and can process a large amount of data from multiple monitoring modules 201 to ensure real-time monitoring and response of fire conditions.

[0053] The present invention also has the following implementation modes on the basis of the above:

[0054] Embodiment 2: An operating method of a water mist fire extinguishing system applied to a high-rise building as described in any one of the above, comprising the following steps:

[0055] Step S1, once the monitoring module 201 detects a fire, it sends the monitoring data to the data integration processing module 202;

[0056] Step S2, the data integration processing module 202 analyzes the monitoring data, and the data integration processing module 202 divides the fire into a first-level fire, a second-level fire or a third-level fire. A first-level fire is a fire detected by the monitoring module 201 in any area, and the monitoring module 201 in the area transmits the monitoring data to the data integration processing module 202 through the control circuit. A second-level fire is a fire detected by all the monitoring modules 201 on any floor, and all the monitoring modules 201 on the floor transmit the monitoring data to the data integration processing module 202 through the control circuit. A third-level fire is a fire detected by all the monitoring modules 201 on any floor and the upper and lower floors adjacent to the floor, and all the monitoring modules 201 on the affected floor and the upper and lower floors adjacent to the affected floor transmit the monitoring data to the data integration processing module 202 through the control circuit. Thus, a multi-layer protective water curtain is constructed to curb the vertical spread of the fire and create conditions for personnel evacuation and fire rescue, such as multi-layer linkage water spraying in the event of a shopping mall fire.

[0057] Step S3: The data integration and processing module 202 generates corresponding first-level response results, second-level response results, or third-level response results according to the fire level and sends them to the response control module 203;

[0058] Step S4: The response control module 203 controls the water mist fire extinguishing device 1 to make a fire extinguishing response according to the response result. The first-level response result is that the response control module 203 controls the water pump group 102 to convey water to the water supply pipe network 103 and controls the area fire extinguishing units in the affected area to open. The water flows out from the area fire extinguishing units in the affected area after passing through the water tank 101, the water pump group 102, and the second main pipeline 1032 in sequence. The second-level response result is that the response control module 203 controls the water pump group 102 to convey water to the water supply pipe network 103, controls the floor valve 104 on the affected floor and all area fire extinguishing units to open. The water flows out from all area fire extinguishing units on the affected floor after passing through the water tank 101, the water pump group 102, the first main pipeline 1031, the second main pipeline 1032, and the floor valve 104 on the affected floor in sequence. The third-level response result is that the response control module 203 controls the water pump group 102 to convey water to the water supply pipe network 103, controls the floor valves 104 on the affected floor and the upper and lower adjacent floors and all area fire extinguishing units to open. The water flows out from all area fire extinguishing units on the affected floor and the upper and lower adjacent floors after passing through the water tank 101, the water pump group 102, the first main pipeline 1031, the second main pipeline 1032, and the floor valves 104 on the affected floor and the upper and lower adjacent floors in sequence. Specifically, during the fire extinguishing process, the temperature sensors and smoke sensors continuously monitor and feedback, and the response control module 203 dynamically adjusts the pressure of the water pump group 102, the opening and closing degrees of the floor valves 104 and / or the area valves 105 to ensure efficient and safe fire extinguishing;

[0059] Step S5: After the fire extinguishing is completed, the response control module 203 controls the water pump group 102, the area fire extinguishing units, and / or the floor valves 104 to close according to the preset program. Specifically, the data integration and processing module 202 can also use the functions of recording and analyzing data to provide data support for subsequent fire prevention and emergency handling.

[0061] (1) By using the monitoring module 201 to monitor the fire situation in each area in real time, the present invention can quickly detect and locate the fire source, achieve early warning.

[0062] (2) The fine water mist fire extinguishing system provided by the present invention has higher stability, safety, and environmental friendliness compared with the gas fire extinguishing system, and lower later maintenance costs. Compared with the traditional water spray system, it can greatly reduce the consumption of water resources. At the same time, through the layered and zoned pipeline layout and the setting of regional fire extinguishing units, this system can only carry out fire extinguishing operations on the affected areas during a fire, avoiding mis-spraying on the unaffected areas, further improving the utilization efficiency of water resources, and reducing the occupation of building resources;

[0063] (3) According to different fire levels, the present invention divides the fine water mist fire extinguishing levels into three levels, precisely extinguishes fires, effectively prevents the spread of fires, automatically adjusts fire extinguishing strategies and resource allocation according to different stages of fires, ensures the safety of personnel evacuation, provides valuable time for firefighters' rescue, and makes the best use of limited water resources. In the event of a first-level fire, only the regional fire extinguishing units in the affected areas are activated to achieve local and rapid fire extinguishing; in the event of second-level and third-level fires, the activation is respectively extended to all regional fire extinguishing units on the entire floor and adjacent floors to ensure that the fire is effectively controlled, while avoiding unnecessary waste of fire extinguishing resources;
