(3) Hidden dangers
Old buildings, poor fireproof conditions: In addition to the large-scale markets built uniformly in recent years, most of the small, medium-sized and old farmers' markets are roof markets, street markets, underground markets, etc., and there are generally problems such as low fire resistance grades, simple and flammable buildings, insufficient fire spacing, lack of fire separation, insufficient safety evacuation channels and exit widths, insufficient fire extinguishing facilities and equipment, commodity distribution without considering fire prevention and extinguishing requirements, excessive density of stall counters and insufficient spacing, and some even occupy fire truck passages. Illegal markets where residential or public buildings are barricaded and cut off roads seriously threaten the fire safety of surrounding buildings. In the event of a fire, it will often cause "burning the camp".
The circulation of personnel is large, the density of personnel is high: the farmers' market commodities are gathered, not only individual commercial households, some state-owned and collective commercial units have also entered the farmers' market to participate in competition, and most of the commodities operated are mainly based on the indispensable commodities that the residents eat, wear and use in their lives, and the customer flow is very large. Especially during the holiday season, the traffic in many markets far exceeds the capacity of the market, and evacuation is more difficult in the event of a fire.
Fire, electricity, gas consumption: in addition to daily lighting, summer exhaust and other electricity in the shops in the farmers' market, the neon lights in the advertising window, the chandeliers, wall lamps, table lamps, colored lights during festivals or exhibitions, and the electric heating appliances used by the residents to cook rice are inseparable from electricity; Some market stores also use LPG cookers in the store; Many markets are front shops and back warehouses, shops in stores, business negotiations, living and living mixed in one room. With fire, electricity and gas points are large. In addition, many markets use fire and electricity, and the installation and use of gas appliances are not unified planning and management, and shopkeepers are prone to fire accidents.
Weak fire safety management: The fire safety of farmers' markets should be the responsibility of their organizers, assisted by the administrative authorities for industry and commerce. However, due to the lack of implementation of the work of the organizers, the lack of coordination of relevant departments, the establishment of fire safety management institutions, and the failure to establish and improve the fire safety management system, the fire safety management system has not been controlled.
(4) Solution
In Zhengzhou Yabang Automobile Technology Industrial Park, each merchant installs and sets up a BlueBird Fire Independent Photoelectric Smoke Detector Alarm, when the smoke detector detects the fire hazard and sends out an alarm signal, it can immediately notify the relevant responsible persons of the property through telephone, SMS, mobile PHONE APP, and the alarm information data can be uploaded to the fire cloud platform through the network to achieve unified supervision.
(5) Customer value
Fire safety prevention ability improvement: Based on the intelligent Internet of Things, the fire prevention system of Yabang Automobile Science and Technology Industrial Park can comprehensively monitor the fire safety status of merchants, and the fire control staff can grasp the dynamic information of fire fighting equipment anytime and anywhere through mobile phones.
Improvement of fire management efficiency: Standardize the business processes of fire control personnel management, inspection, inspection, etc., improve work efficiency, save labor costs and management costs.
Improvement of supervision by the government and fire departments: Build an informatized, three-dimensional, full-coverage social fire prevention and control system, realize real-time online monitoring of fire fighting equipment, and grasp the operation of equipment in real time for 24 hours without being on the scene. Enhance the supervision and control of the government and fire departments, and effectively protect the safety of people's lives and property. 【Source: Bluebird Fire】
2. Fire protection solution for Nanjing Jiangbei energy storage power station
The Nanjing Jiangbei Energy Storage Power Station invested and built by Pinggao Group is one of the core elements of the State Grid Nanjing". "The project is not only a model high-quality project for the integration of multiple stations in the domestic power grid at present, but also the largest "charging treasure" in Nanjing. The maximum charge and discharge power is 110.88 MW, which can store about 220,000 kWh of electricity (redundant configuration), and the AC side can discharge 193.6 MWh. "The whole station adopts the standard modern style design, the construction scale is 110.88MW/193.6MWh, which is composed of 88 prefabricated cabin energy storage batteries, 176 sets of 630kW energy storage converters (PCS), 44 sets of 2800kVA boost transformer (with box shell), 44 sets of 10kV in-situ switchgear and 10kV power distribution devices. It is the largest electrochemical energy storage power station on the domestic power grid side of the mainland.
The project adopts the prefabricated cabin fire protection system of the second-generation lithium iron phosphate battery of Nanxia Company.
The working principle of the second-generation lithium battery energy storage and fire protection integrated solution of Nanxing:
- In the early stage of battery runaway, the concentration of dangerous gases of 1PPM and below can be detected by a special gas detection device.
- For each battery module using water as a fire extinguishing and cooling medium, fast speed, no re-ignition, no water stains, low temperature of the battery and adjacent batteries effectively reduce the occurrence and progress of thermal runaway, battery utilization after the accident can be high.
- For the battery compartment as a whole using a gas fire extinguishing system, the experimental report spray time is 5.8 seconds, the fire extinguishing time is 4.3 seconds, and it has an explosion suppression effect.
The second generation of products has the following advantages over the first generation of the fire extinguishing system scheme with heptafluoropropane gas alone:
- Through the lithium battery special gas detector, it is possible to detect the initial runaway state of the battery and eliminate the accident in the bud.
- For each battery module, a special sprinkler is set up to extinguish the fire and cool down by using water and gas as a medium.
- Through the linkage between the alarm controller developed by Nanxuan and BMS and related equipment, the battery operation is highly efficient and highly secure, and the real-time monitoring of field devices through the digital platform of Nancong and the upload of data to the cloud and customer terminals greatly improve the efficiency of operation and maintenance. 【Source: Nan Consumer Group】
3. Intelligent fire protection solution for warehouse plant
Following the double eleven, double twelve, Christmas, spring festival followed; before and after this period, the major factories, warehouses also ushered in the busiest time, a large number of raw materials in the factory, warehouses piled up with goods, coupled with the seasonal characteristics of dry days, there are great fire safety hazards.
Hefei, Anhui: On November 11, a fire broke out in an aluminum rubber products company in Changfeng County, Hefei, and the fire material at the scene was sponge, glue, diesel, etc., but fortunately there were no casualties.
Shaoxing, Zhejiang: On November 14, a fire broke out in an industrial park factory building in Anchang Street, Shaoxing, Zhejiang, and the fire and smoke surrounded the building, and thick black smoke floated above the entire building, and the fire was more serious.
Nanchang, Jiangxi: On December 14, a fire broke out in a warehouse of "Fresenius Kabi" Medical Device Co., Ltd. at No. 1701 Qinglan Avenue. The fire has killed 5 people and injured 1.
In the daily production and management process, enterprises often ignore fire safety problems and do not conscientiously perform the fire safety duties of the unit, which leads to the occurrence of fire or leads to the aggravation of fire events.
(1) What are the common fire safety hazards in the management process of the plant warehouse
Factory buildings, warehouses goods stacking management chaos, there is no strict implementation of fire prevention requirements: whether it is a factory or warehouse have clear fire safety management norms and standards, for the placement of goods have relatively high requirements, but many enterprises in order to make full use of the space of goods stacked highly concentrated, showing a large number, density, mixed types of characteristics, no fire partition, once a fire, easy to appear fire camp situation.
The fire alarm system and automatic fire extinguishing system in the factory area are not perfect: many factories and warehouses have not set up an effective fire alarm system in order to save costs, and the smoke alarm and sprinkler equipment are not designed in accordance with the standard, resulting in difficult to find and fight in time in the early stage of the fire, which is easy to lead to the expansion of the fire.
Fire fighting equipment is in a state of decoration, there is no regular inspection and maintenance: due to the neglect of fire safety, the fire fighting facilities in the factory area are not regularly inspected and maintained, resulting in the occurrence of ineffective fire extinguishers and the occurrence of water hydrants when they need to be used, and the best time to extinguish fires is delayed.
(2) Intelligent fire fighting, anti-elimination combination
Automatic supervision and early warning, reduce the probability of fire evolving into fire: smart fire control of the supervision area for automatic supervision, when the fire is found, can be timely early warning and remote notification, so that the supervision personnel can find the fire in time, timely disposal, so as to extinguish the early stage, extinguish the early stage.
24-hour intelligence, reduce the pressure of personnel supervision: smart fire protection is the use of the Internet of Things working mode, the traditional fire equipment, early warning equipment and the Internet connection, to achieve fire management information, intelligence, real-time, always monitor the fire situation, reduce the pressure of personnel supervision, improve the initiative of supervision and the accuracy and timeliness of results.
Automatic monitoring of the effectiveness of fire fighting equipment, guarantee function: For the supervision of the effectiveness of fire fighting equipment, the intelligent fire protection system can also be real-time and comprehensive, and the existence status of the equipment can be timely understood by connecting the monitoring equipment at the end of the fire fighting equipment, and the water level and water pressure in the system can be monitored in a timely manner to ensure that the fire water demand is met.
Fire passage monitoring to solve the problem of item blockage: For the problem of blocking the door of the fire passage and fire hydrant, the intelligent video surveillance of the intelligent fire protection can detect the fire passage, the fire hydrant doorway and other areas if there is a foreign body stored for a long time, it will be alarmed to avoid the safety hazard caused by the blockage problem.
(3) Advantages of smart fire protection programs
