Description

Technical Field

[0001] This utility model relates to the field of fire alarm processing technology, and more specifically, to a fire alarm processing device for liquid ammonia storage tanks. Background Technology

[0002] Liquid ammonia is a colorless liquid with a strong, pungent odor. As an important chemical raw material, ammonia is usually converted from gaseous ammonia to liquid ammonia through pressurization or cooling for convenient transportation and storage. Liquid ammonia can then be stored in liquid ammonia storage tanks, which can also be equipped with appropriate fire alarm devices for early warning.

[0003] In the existing technology, there is a lack of safe and stable fire alarm devices for liquid ammonia storage tanks. When the sensing element is damaged, it cannot issue a fault warning, affecting the normal use of the fire alarm device on the liquid ammonia storage tank. Furthermore, the practicality and durability of the fire alarm device itself need to be improved. For example, the utility model patent with announcement number CN204201474U discloses a liquid ammonia storage safety alarm device, which includes a temperature sensor fixed on the liquid ammonia tank, a concentration sensor located outside the tank, and a pressure sensor connected to the liquid ammonia tank pipeline. The temperature sensor, concentration sensor, and pressure sensor are connected to each other through circuit control lines, and a spray device is set up to cool down the tank after the sensing conditions are met. Its safety alarm structure is not safe and stable enough. When the sensing element is damaged, it cannot issue a fault warning in time, affecting the normal use of the fire alarm device on the liquid ammonia storage tank. The practicality and safety of this device also need to be improved. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] This embodiment places the device next to the liquid ammonia storage tank. The temperature-sensing cable connected to the fire detector is wrapped around the outer surface of the tank for monitoring. When the temperature of the liquid ammonia storage tank becomes abnormally high, a signal is sent to the fire detector, thereby controlling the sprinkler assembly to spray water onto the tank, achieving the function of cooling and extinguishing the fire. Simultaneously, the temperature-sensing cable is connected to a cable fault tester, which can issue an alarm indicator light in case of cable failure, facilitating timely handling and repair by personnel. This greatly enhances the convenience of using the fire alarm handling device. The specific implementation method is as follows:

[0030] like Figures 1 to 4As shown, a fire alarm and handling device for a liquid ammonia storage tank includes a temperature-sensing cable 2, a control box 3, and a fault detection component. The control box 3 is located next to the liquid ammonia storage tank 1. A fire detector 12 is installed inside the control box 3. The detection end of the fire detector 12 is equipped with the temperature-sensing cable 2, which is located on the outer surface of the liquid ammonia storage tank 1. A sprinkler assembly connected to the fire detector 12 is installed directly above the liquid ammonia storage tank 1. A fault detection component is installed on the temperature-sensing cable 2. The fault detection component includes an abnormal indicator light 10 and a cable fault tester 13. The abnormal indicator light 10 is installed on the top of the control box 3. The cable fault tester 13 is installed inside the control box 3. The tail end of the temperature-sensing cable 2 passes through the cable fault tester 13 and is connected to the fire detector 12. The device is installed next to the liquid ammonia storage tank 1. The temperature sensing cable 2, which is connected to the fire detector 12, can be wrapped around the outer surface of the liquid ammonia storage tank 1 for monitoring. When the temperature of the liquid ammonia storage tank 1 is abnormally high, a signal can be sent to the fire detector 12, thereby controlling the sprinkler assembly to spray water onto the liquid ammonia storage tank 1 to achieve the function of cooling and extinguishing the fire. At the same time, the temperature sensing cable 2 is connected to a cable fault tester 13, which can issue an alert through the abnormal indicator light 10 when the temperature sensing cable 2 fails, so that the staff can handle and repair it in time, which brings great convenience to the use of the fire alarm handling device.

[0031] The temperature-sensing cable 2 is evenly wound around the outer surface of the liquid ammonia storage tank 1, with its two ends connected to the detection end and receiving end of the fire detector 12, respectively. The temperature-sensing cable 2 is a linear temperature detector, a type of detector that responds to fire parameters around a continuous line. There are two main types of linear temperature detectors: fiber optic and cable. The two most widely used and mature linear temperature detectors worldwide are analog linear temperature detectors and digital linear temperature detectors. They are primarily used for fire detection and alarm systems. By working in conjunction with the fire detector 12, the temperature of the surface of the liquid ammonia storage tank 1 can be monitored in close proximity.

[0032] An alarm 11 is installed on the top of the control box 3, and the alarm 11 is connected to the fire detector 12. The alarm 11 and the fire detector 12 are electrically connected. When the temperature of the liquid ammonia storage tank 1 is abnormally high, the alarm 11 located on the control box 3 will sound an alarm to remind the staff to deal with it in time.

[0033] The spray assembly includes a water pump 5 and a spray pipe 7. The water pump 5 is fixedly installed at the center of the top of the control box 3. The output end of the water pump 5 is connected to the spray pipe 7. The end of the spray pipe 7 away from the water pump 5 is positioned directly above the liquid ammonia storage tank 1 via a support frame 8. Several nozzles 9 are provided on the lower surface of the spray pipe 7, passing through the support frame 8 and pointing towards the liquid ammonia storage tank 1. The spray assembly, consisting of the water pump 5 and the spray pipe 7, and positioned directly above the liquid ammonia storage tank 1, can uniformly spray the surface of the liquid ammonia storage tank 1 through the several nozzles 9, thereby improving the spraying effect.

[0034] The input end of the water pump 5 is connected to the water inlet pipe 6, which is connected to a water supply source. The water inlet pipe 6 is equipped with an inlet valve 15. By opening the water inlet pipe 6 through the inlet valve 15, water can be supplied for spraying.

[0035] The control box 3 is equipped with a display 4, which is electrically connected to the temperature sensing cable 2 via the fire detector 12. The display 4 shows the specific temperature of the liquid ammonia storage tank 1 monitored by the temperature sensing cable 2.

[0036] The control box 3 has a door on the front and several ventilation holes on its side walls. The door allows for easy opening of the control box 3, and the ventilation holes facilitate heat dissipation.

[0037] The outer surface of the control box 3 is provided with a protective reinforcing plate 16, and the inner wall of the control box 3 is provided with an insulating layer 17. The protective reinforcing plate 16 on the outside of the control box 3 can improve the strength of the control box 3 and make it less prone to damage. The insulating layer 17 on the inside of the control box 3 can improve the control insulation effect and avoid leakage and electric shock. The insulating layer 17 is made of epoxy resin insulating material.

[0038] Inside the control box 3, next to the fire detector 12, there is a signal transmission module 14. Through the signal transmission module 14, it can be connected to an external DCS control system, so that staff can remotely control it from the control host.

[0039] The control box 3 is made of stainless steel, and the temperature sensing cable 2 is made of thermally insulating material.

[0040] Working Principle: The device is installed next to the liquid ammonia storage tank. The temperature-sensing cable connected to the fire detector is wrapped around the outer surface of the tank for monitoring. When the temperature of the liquid ammonia storage tank becomes abnormally high, a signal is sent to the fire detector, which then controls the sprinkler assembly to spray water onto the tank, achieving the function of cooling and extinguishing the fire. Simultaneously, the temperature-sensing cable is connected to a cable fault tester, which can issue an abnormality indicator light to alert personnel in case of cable faults, facilitating timely handling and repair. This greatly enhances the convenience of using the fire alarm system. When the temperature of the liquid ammonia storage tank becomes abnormally high, the alarm located on the control box will sound, reminding personnel to take immediate action. The sprinkler assembly consists of a water pump and sprinkler pipes positioned directly above the liquid ammonia storage tank, allowing for uniform spraying of the tank's surface and improving the spraying effect. The protective reinforcement plate on the outside of the control box increases its strength, making it less prone to damage. The insulation layer inside the control box improves insulation, preventing leakage and electric shock.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
