Description

Technical Field

[0001] This utility model relates to a fire protection system for liquid ammonia tanks, specifically a fire monitor system for liquid ammonia tanks. Background Technology

[0002] Liquid ammonia is classified as a hazardous chemical, and liquid ammonia storage tanks are subject to strict supervision as major hazard sources. Leaks can cause poisoning and the formation of explosive gases that can ignite and explode upon contact with a flame. The safe and stable operation of liquid ammonia storage tanks, as well as the timely and effective handling of initial leaks, are crucial not only to the safety of the company's personnel and property but also to the safety of personnel and property in surrounding businesses, and even to the stability of the entire society. Therefore, the safe operation of liquid ammonia storage tanks is of paramount importance.

[0003] Existing liquid ammonia storage tanks use an automatic sprinkler system on top. This serves two purposes: first, it prevents solar radiation by automatically spraying water to cool the tank when the temperature becomes too high; second, it absorbs ammonia gas, activating the automatic sprinkler system to absorb both the liquid ammonia and the gas in case of leakage, thus controlling ammonia contamination. However, this design cannot provide comprehensive water spraying for the liquid ammonia tank. If this is not controlled promptly and effectively, it will inevitably lead to a larger explosion, causing devastating harm to rescue personnel. Utility Model Content

[0004] The purpose of this invention is to provide a fire monitor extinguishing system for liquid ammonia tanks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fire suppression system for liquid ammonia tanks includes a fire-fighting pipeline network, a pipeline filter, a remote-controlled valve, a fire monitor operating platform, a remote-controlled fire monitor, a control box, a video surveillance camera, a video surveillance display screen, a centralized fire control cabinet, an ammonia tank containment dike, and horizontal ammonia tanks. The horizontal ammonia tanks are evenly spaced on the ammonia tank containment dike. The fire monitor operating platform is symmetrically installed on the side corners of the ammonia tank containment dike, and a remote-controlled fire monitor is mounted on the fire monitor operating platform. The remote-controlled fire monitor includes a first mounting frame, with mounting components for mounting the fire monitor operating platform at the four bottom corners of the first mounting frame. A rotating rod is rotatably mounted on the upper end of the first mounting frame. A sealing cover is fixedly installed on the outer wall of the first mounting frame. A rotation drive component for driving the rotating rod to rotate is installed on the first mounting frame inside the sealing cover. Both ends of the rotating rod are fixedly mounted... The system includes a connecting column, the top of which is connected to the main body of the fire cannon via a mounting base. The mounting base is equipped with an exhaust assembly for venting the end of the fire cannon. Inside the main body of the fire cannon, several mounting components are fixedly installed at equal intervals. An annular connecting pipe is fixedly installed at the inner end of each mounting component, and several atomizing nozzles are evenly spaced at the inner end of the annular connecting pipe. The top of the annular connecting pipe has a water inlet pipe connected to a water supply pipe, which in turn is connected to a fire protection network. A video surveillance camera for real-time monitoring of the horizontal ammonia tank is installed at one corner of the ammonia tank dike. A control box for on-site control of the remote-controlled fire cannon is installed outside the ammonia tank dike. The video surveillance display screen controls the video surveillance camera via wireless signals. The centralized fire control cabinet controls the control box and the remote-controlled fire cannon via wireless signals.

[0007] Preferably, the rotation drive assembly includes a drive part fixedly connected to the inner wall of the first mounting frame, and a drive gear is provided on the output shaft of the drive part. A driven gear is meshed on the drive gear, and the driven gear is connected to the rotating rod.

[0008] Preferably, a remote controller is installed on the sealing cover.

[0009] Preferably, the ventilation assembly includes a ventilation pump fixedly connected to the mounting base, and the ventilation pump has a ventilation pipe at its end, which passes through the barrel body and is connected to the ventilation hood.

[0010] Preferably, a pipe filter and a remote-controlled electric valve are installed on the water inlet pipe, and the remote-controlled electric valve is located on the water inlet pipe near the side of the remote-controlled fire monitor.

[0011] Compared with existing technologies, the advantages of this utility model are as follows: This utility model enables remote control of a radio frequency monitoring camera via a video monitoring display screen to monitor the horizontal ammonia tanks mounted on the ammonia tank containment dike. It also allows for convenient observation of fire monitors extinguishing fires and diluting ammonia gas on the horizontal ammonia tanks mounted on the containment dike, thus facilitating fire suppression of liquid ammonia tanks. Furthermore, this utility model operates through a centralized fire control cabinet, eliminating the need for a control box and remote-controlled fire monitors. This allows for rapid fire suppression of burning horizontal ammonia tanks using remote-controlled fire monitors. After the fire is extinguished, it continues to dilute the ammonia gas, reducing the ammonia concentration until the leak is repaired, thus ensuring the maximum safety of rescue personnel. This utility model uses a rotating drive component to drive a rotating rod to rotate. The rotating rod, through a connecting column, drives the mounting base to adjust its rotational orientation. The mounting base simultaneously drives the barrel body to adjust its angle. This allows for adjustment of the barrel body's angle, facilitating atomized water spraying to extinguish fires from all directions on horizontal ammonia tanks installed at equal intervals on the ammonia tank dike. It also reduces the ammonia concentration until the leak is repaired, ensuring the maximum safety of rescue personnel. Attached Figure Description

However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] See Figure 1-5In this embodiment of the present invention, a fire extinguishing system for liquid ammonia tanks includes a fire-fighting pipeline network 1, a pipeline filter 2, a remote-controlled electric valve 3, a fire monitor operating platform 4, a remote-controlled fire monitor 5, a control box 6, a video surveillance camera 7, a video surveillance display screen 8, a centralized fire control cabinet 9, an ammonia tank containment dam 10, and horizontal ammonia tanks 11. The horizontal ammonia tanks 11 are evenly spaced on the ammonia tank containment dam 10. The fire monitor operating platform 4 is symmetrically installed on the side corners of the ammonia tank containment dam 10, and a remote-controlled fire monitor 5 is installed on the fire monitor operating platform 4. The remote-controlled fire monitor 5 includes a first mounting frame 51, and mounting components 52 for mounting the fire monitor operating platform 4 are provided at the four corners of the bottom of the first mounting frame 51. A rotating rod 53 is rotatably mounted on the upper end of the first mounting frame 51. A sealing cover 55 is fixedly installed on the outer wall of the first mounting frame 51. A rotation drive component 54 for driving the rotating rod 53 to rotate is installed on the first mounting frame 51 located inside the sealing cover 55. The two ends of the rotating rod 53 are fixedly mounted. A connecting column 57 is provided, and the top of the connecting column 57 is connected to the barrel body 59 via a mounting base 58. The mounting base 58 is equipped with an exhaust assembly 510 for exhausting air from the end of the barrel body 59. Several mounting parts 511 are fixedly installed at equal intervals inside the barrel body 59. An annular connecting pipe 512 is fixedly installed at the inner end of the mounting part 511. Several atomizing nozzles 513 are evenly arranged at equal intervals at the inner end of the annular connecting pipe 512. The water inlet pipe 515 at the top of the annular connecting pipe 512 is connected to a water supply pipe 514, which is connected to the fire protection network 1. A video monitoring camera 7 for real-time monitoring of the horizontal ammonia tank 11 is installed at one corner of the ammonia tank dike 10. A control box 6 for on-site control of the remote-controlled fire monitor 5 is installed outside the ammonia tank dike 10. The video monitoring display screen 8 is used to control the video monitoring camera 7 via wireless signals. The fire protection centralized control cabinet 9 is used to control the control box 6 and the remote-controlled fire monitor 5 via wireless signals.

[0022] This invention places the fire monitor operating platform 4 and the remote-controlled fire monitor 5 at the two corners of the ammonia tank containment dam 10, and uses a video monitoring camera 7 set at one corner to monitor the horizontal ammonia tanks 11 installed at equal intervals on the ammonia tank containment dam 10. A rotating drive assembly 54 drives the rotating rod 53 to rotate, and the rotating rod 53, through a connecting column 57, drives the mounting base 58 to adjust its rotational orientation. The mounting base 58 simultaneously drives the monitor body 59 to adjust its angle. The aqueous solution is supplied through the fire-fighting pipeline network 1 via the inlet pipe 5. 15 and water supply pipe 514 supply liquid to the annular connecting pipe 512. The atomizing nozzles 513 spaced at equal intervals on the annular connecting pipe 512 spray water inside the barrel body 59. In conjunction with the exhaust component 510, the atomized water mist is sprayed onto the horizontal ammonia tank 11 stored on the ammonia tank dike 10 to quickly extinguish the fire in the horizontal ammonia tank 11. After the fire is extinguished, it continues to dilute the ammonia gas and reduce the ammonia concentration until the leak point is dealt with, providing the greatest possible safety for the rescue personnel.

[0023] See Figure 3 In one embodiment of the present invention, the mounting component 52 includes a second mounting frame 521 that is fixedly connected to the four bottom corners of the first mounting frame 51. The second mounting frame 521 is threaded with mounting bolts 522. By manually rotating the mounting bolts 522, the second mounting frame 521 can be threadedly connected to the fire monitor operating platform 4, thereby achieving fixed installation of the second mounting frame 521 and the fire monitor operating platform 4.

[0024] See Figure 4 In one embodiment of this utility model, the rotation drive assembly 54 includes a drive part 541 fixedly connected to the inner wall of the first mounting frame 51. A drive gear 542 is provided on the output shaft of the drive part 541. A driven gear 543 is meshed on the drive gear 542. The driven gear 543 is connected to the rotating rod 53. Through the operation of the drive part 541, the drive part 541 controls the drive gear 542 to drive the driven gear 543 to rotate. The driven gear 543 can drive the rotating rod 53 to adjust the rotational orientation, which can facilitate the adjustment of the angle of the barrel body 59.

[0025] See Figure 4 In one embodiment of this utility model, a remote controller 56 is installed on the sealing cover 55. The remote controller 56 can not only control the remote fire monitor 5 to work on-site, but also control the remote fire monitor 5 to work remotely, thereby facilitating the remote fire monitor 5 to spray water for fire extinguishing.

[0026] See Figure 5In one embodiment of this utility model, the exhaust assembly 510 includes an exhaust pump 5101 fixedly connected to the mounting base 58. An exhaust pipe 5102 is provided at the end of the exhaust pump 5101. The exhaust pipe 5102 passes through the barrel body 59 and is connected to the exhaust hood 5103. When the exhaust pump 5101 works, it supplies air through the exhaust pipe 5102 and the exhaust hood 5103. The exhaust hood 5103 blows out the water mist inside the barrel body 59, which facilitates water spraying and fire extinguishing of the horizontal ammonia tank 11 and reduces the concentration of leaked ammonia gas, thereby providing maximum safety for rescue personnel.

[0027] See Figure 1 and Figure 2 In one embodiment of this utility model, a pipeline filter 2 and a remote electric control valve 3 are installed on the water inlet pipe 515. The remote electric control valve 3 is located on the water inlet pipe 515 near the remote-controlled fire monitor 5. The water inlet pipe 515 is opened by the remote electric control valve 3, and the fire-fighting pipeline 1 sends the aqueous solution into the water supply pipe 514 through the water inlet pipe 515. The pipeline filter 2 filters the flowing aqueous solution, which facilitates the remote-controlled fire monitor 5 to spray water onto the horizontal ammonia tank 11.

[0028] Working Principle: This utility model uses a video monitoring display screen 8 to control a video monitoring camera 7 to monitor the horizontal ammonia tanks 11, which are evenly spaced inside the ammonia tank containment dam 10. In the event of a leak or fire in the horizontal ammonia tank 11, the fire-fighting system is controlled by a remote controller 56 on the fire-fighting central control cabinet 9, control box 6, and remote-controlled fire monitor 5. The remote-controlled valve 3 is opened, and the aqueous solution inside the fire-fighting pipeline 1 is filtered by the pipeline filter 2 before being added to the inlet pipe 515. Water is then supplied to the annular connecting pipe 512 via the supply pipe 514. The atomizing nozzles 513, evenly spaced on the annular connecting pipe 512, supply water mist to the inside of the cannon body 59. The drive unit 541 operates... The drive unit 541 drives the active gear 542 to rotate the meshing driven gear 543. The driven gear 543 can drive the rotating rod 53 to rotate. The rotating rod 53 drives the barrel body 59 to rotate at an adjustable angle through the connecting column 57 and the mounting base 58. The exhaust pump 5101 works to supply air to the exhaust hood 5103 through the exhaust pipe 5102. The exhaust hood 5103 blows out the aqueous solution inside the barrel body 59, thereby spraying water to treat the horizontal ammonia tanks 11 that are evenly spaced inside the ammonia tank dike 10. This allows for rapid fire extinguishing of the horizontal ammonia tanks 11 that are on fire. After the fire is extinguished, the water continues to dilute the ammonia gas and reduce the ammonia concentration until the leak point is dealt with, providing maximum safety for rescue personnel.
