Description

Technical Field

[0001] This utility model relates to the field of fire protection engineering technology, specifically to an indoor rapid smoke prevention and exhaust device for fire protection engineering. Background Technology

[0002] When a fire occurs, the ignition point produces thick smoke. Due to the rising of hot air, a large amount of thick smoke will float in the upper layer. The thick smoke often contains a large number of harmful substances. If people are not properly protected when escaping through the thick smoke, they can easily inhale the smoke, leading to fainting or suffocation. At the same time, the eyes will also be irritated by the smoke, causing stinging and making it impossible to open them. Smoke becomes an obstacle to escaping a fire.

[0003] For example, the indoor rapid smoke control and exhaust device for fire protection engineering disclosed in authorization announcement number CN216204026U includes a fire room, on which a box is fixedly installed. A smoke inlet is provided on the box at a connection point to the fire room. One end of the smoke inlet is connected to a blower, and an exhaust duct is connected to the blower. A connector is provided between the exhaust duct and the blower. The other end of the exhaust duct is connected to a smoke exhaust fan, and a purifier is provided between the smoke exhaust fan and the exhaust duct. The beneficial effects of this utility model are as follows: The smoke is exhausted into the atmosphere by the smoke exhaust fan. To prevent environmental pollution, a purifier is provided between the smoke exhaust fan and the exhaust duct. The smoke is filtered through an activated carbon filter, a pre-filter, and a high-efficiency filter, thereby reducing the pollution of the smoke to the environment.

[0004] Although the aforementioned patent achieves basic smoke exhaust function and purifies the air through a filter, when high-temperature flue gas above 300°C passes directly through the filtration system, it will not only instantly melt the high-efficiency PP filter (melting point 160°C), reducing the filtration efficiency to zero, but it will also cause the activated carbon to spontaneously combust (ignition point 300°C). Even more dangerously, the high-temperature exhaust air may ignite the building's exterior wall insulation material. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-3 As shown, this utility model provides a technical solution:

[0025] An indoor rapid smoke control and exhaust device for fire protection engineering includes a smoke exhaust box 1, with a partition 2 fixedly connected inside. A spray chamber 3 is provided on the left side of the partition 2, and a water tank 4 is provided on the right side of the partition 2. A spray filtration mechanism is provided inside the smoke exhaust box 1 and above the spray chamber 3. The spray filtration mechanism includes a water pump 11 vertically fixed to the middle of the top left side of the smoke exhaust box 1. The output end of the water pump 11 extends into the interior of the spray chamber 3 and is fixedly connected to a sprayer 12. The input end of the water pump 11 is fixedly connected to a water suction pipe 13. The end of the water suction pipe 13 away from the water pump 11 extends into the interior of the water tank 4 and is fixedly connected to an activated carbon filter 14. The spray filtration mechanism also includes a spray pipe 15 that is parallel to and horizontally fixed to the inner wall of the upper side of the partition 2 located in the spray chamber 3, and several air holes 16 that penetrate and open at the upper end of the partition 2. The air holes 16 are connected to the spray pipe 15. Several spray holes 17 are parallel to and penetrate the top of the spray pipe 15. A clean air outlet 18 is connected to the top left side of the smoke exhaust box 1, and a water outlet 19 is fixedly connected to the bottom left side of the smoke exhaust box 1. An immersion filtration mechanism is provided inside the smoke exhaust box 1 and in the middle of the water tank 4. The immersion filtration mechanism includes a fixed... An air pump 5 is connected to the top center of the right side of the smoke exhaust box 1. The input end of the air pump 5 is fixedly connected to a flue gas inlet pipe 6, and the output end of the air pump 5 extends into the interior of the water tank 4 and is fixedly connected to a flue gas outlet pipe 7. A pipe joint 8 is fixedly connected to the upper right side of the smoke exhaust box 1, and a drain outlet 9 is fixedly connected to the lower right side of the smoke exhaust box 1. A level gauge 10 is fixedly connected to the middle right side of the smoke exhaust box 1. The pipe joint 8 is connected to the fire protection pipe and is equipped with an electric valve. The electric valve and the level sensor are connected through a controller. When the fire protection system sends a fire command, the electric valve opens, and the air pump 5 and the water pump 11 also open at the same time. Throughout the process, the level sensor monitors the level of the water tank 4 in real time and adjusts the opening and closing of the electric valve through the controller to maintain the optimal working level. The drain outlet 9 is used to periodically remove sediment and impurities.

[0026] In this embodiment, the dual filtration structure of water tank 4 filtration and spray purification, as well as the coordinated operation with the fire water supply system, achieves graded and efficient purification of smoke particles, solving the problems of incomplete purification and inability to effectively link with the fire protection system in traditional mechanical filtration devices.

[0027] Furthermore, by directly contacting the atomized spray system with the high-temperature flue gas for heat exchange, the flue gas is rapidly cooled down, solving the safety hazards of equipment damage and secondary ignition risks that exist when the exhaust device is dealing with high-temperature flue gas.

[0028] Working principle: When the fire protection system detects a fire and issues a command, the controller simultaneously starts the electric valve, air pump 5, and water pump 11. After the electric valve opens, water in the fire protection pipeline enters the water tank 4 through the pipe joint 8 to replenish the water volume. The air pump 5 quickly draws in the high-temperature smoke from the room through the smoke inlet pipe 6 and discharges it into the water tank 4 through the smoke outlet pipe 7 for the first filtration treatment. After the smoke comes into full contact with the water in the water tank 4, most of the smoke particles and harmful substances are adsorbed by the water. At the same time, the high-temperature smoke is initially cooled. The gas that has undergone preliminary purification enters the nozzle 15 through the air hole 16 at the upper end of the partition 2. Meanwhile, the water pump 11 draws water from the water tank 4 through the water pipe 13 and purifies it through the activated carbon filter 14 before delivering it to the sprayer 12. The sprayer 12 sprays the purified liquid evenly through the spray nozzle 17, forming a countercurrent contact with the rising gas to complete the second filtration process. In this process, not only can fine particles and harmful substances in the gas be further removed, but the temperature of the flue gas can also be significantly reduced through the evaporation of the liquid. Finally, the gas that meets the purification standard and has a suitable temperature is discharged to the outdoor safe area through the clean gas outlet 18, and the used water is discharged from the system through the water outlet 19.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
