[0017] Other features and advantages of the present application will be described in detail in the following detailed description. BRIEF DESCRIPTION OF DRAWINGS
[0018] The accompanying drawings, which form a part of this application, are included to provide a further understanding of the application and are incorporated in and constitute a part of this application. The drawings illustrate embodiments of the present application and, together with the description, serve to explain the application. In the drawings:
[0019] Figure 1 FIG. 1 is a schematic view of a fire water tank heat tracing system according to a preferred embodiment of the present application. DETAILED DESCRIPTION
[0020] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
[0021] In cold weather in cold regions, the heat preservation and heating of the fire water tank in the airport oil depot is to ensure that the fire is extinguished in the case of oil depot fire and timely fire extinguishing treatment. At present, although there are ways to heat and preserve the fire water tank to prevent the freezing of the fire water, for example, electric heat preservation belt and / or warm ring pipe, but the staff will keep heating the fire water tank to avoid freezing, which causes a lot of waste of electric power and heat energy.
[0022] Therefore, as Figure 1 shown, the application provides a fire water tank heat preservation system, which comprises: a fire water tank heating and heat preservation device, which is arranged in and / or outside the fire water tank 1, and is used for heating and heat preserving the water in the fire water tank 1; and a temperature control device, which is used for opening or closing the fire water tank heating and heat preservation device according to the water temperature in the fire water tank 1.
[0023] The fire water tank heating and heat preservation device uses heat energy and electric energy to heat the water in the fire water tank 1. The freezing of the water in the fire water tank 1 due to too low temperature is avoided, so that the situation that the water cannot be pumped out when used is avoided.
[0024] The temperature control device is connected with the power system, and is used for monitoring the water temperature in the fire water tank 1 at any time, and opening or closing the fire water tank heating and heat preservation device according to the change of the real-time water temperature. The fire water tank heat preservation system further comprises a power distribution control cabinet 6, which is used for providing electric power for the fire water tank heating and heat preservation device and the temperature control device. The temperature control device is arranged in the power distribution control cabinet 6. The power distribution control cabinet 6 is further provided with a storage type sound and light alarm, which can issue an alarm when power failure occurs, so as to remind the surrounding staff to handle the problem on site.
[0025] The water temperature in the fire water tank 1 is determined according to the location and weather condition of the region, and generally needs to be controlled in the range of 5℃ to 10℃. In the extremely cold regions, for example, the northwest and northeast regions of China, the water temperature needs to be greater than or equal to 10℃. When the water temperature is 10℃, the temperature control device closes the fire water tank heating and heat preservation device, and when the water temperature is 5℃, the temperature control device opens the fire water tank heating and heat preservation device. Generally, when the water temperature is greater than 10℃, the fire water tank heating and heat preservation device does not work, and only plays a heat preservation role.
[0026] The fire water tank heat preservation system provided by the application uses the temperature control device to monitor the water temperature in the fire water tank in real time, and automatically controls the opening or closing of the fire water tank heating and heat preservation device, so that the consumption of a large amount of electric power and heat energy caused by the long-term opening of the fire water tank heating and heat preservation device is avoided, and the operation cost is increased.
[0027] According to a preferred embodiment of the present application, the fire water tank heating and insulation device can comprise a heating ring pipe 4 for heating the water in the fire water tank 1 and / or an electric heat tracing insulation device 3 for heating and / or insulating the water in the fire water tank 1. When the water temperature in the fire water tank 1 is 5°C, only the heating ring pipe 4 is turned on, and the hot water in the heating ring pipe 4 circulates to heat the surrounding water, preventing the water from freezing. When the ambient temperature is slightly cold, the heating ring pipe 4 and the electric heat tracing insulation device 3 are used simultaneously, and the electric heat tracing insulation device 3 does not heat, but only insulates. When the ambient temperature is extremely cold, the heating ring pipe 4 and the electric heat tracing insulation device 3 are turned on to heat and insulate the water in the fire water tank 1, preventing the water from freezing. According to different environmental conditions or temperatures, the heating ring pipe 4 and / or the electric heat tracing insulation device 3 can be selected to avoid waste of heat energy or electricity.
[0028] The heating ring pipe 4 can be used in a suitable manner. Preferably, the heating ring pipe 4 can use municipal heating pipelines as the heating ring pipe 4, or natural gas or electricity can be used to heat the water in the heating ring pipe 4. The heating ring pipe 4 comprises a first heating ring pipe 41 arranged outside the fire water tank 1 and a second heating ring pipe 42 arranged inside the fire water tank 1. The first heating ring pipe 41 comprises an inlet pipe and an outlet pipe. The water in the heating ring pipe 4 enters the second heating ring pipe 42 from the inlet pipe and flows out through the outlet pipe, so that the hot water flows in the heating ring pipe 4 to heat the surrounding water. The flow rate of the water in the heating ring pipe 4 can also be set as needed. When the temperature is relatively cold, the water in the heating ring pipe 4 needs to be pressurized to increase the flow rate of the hot water in the heating ring pipe 4 and improve the heat dissipation rate of the heating ring pipe 4. The second heating ring pipe 42 can be arranged at a suitable position inside the fire water tank 1, for example, it can be arranged on the side or in the middle of the fire water tank 1. In the present application, the second heating ring pipe 42 is arranged at the bottom of the fire water tank 1. After the water in the fire water tank 1 is heated, the density decreases and naturally rises. The cold water sinks to the bottom, continuously realizing the heating and circulation of the water in the fire water tank 1. The inlet pipe and the outlet pipe are arranged under the ground outside the fire water tank 1, which can reduce the floor space outside the fire water tank 1 and does not affect the above buildings and traffic requirements. In addition, the combination of the first heating ring pipe 41 arranged under the ground and the second heating ring pipe 42 arranged at the bottom of the fire water tank 1 can save pipeline routes and reduce costs.
[0029] According to a preferred embodiment of the present application, the electric heat tracing insulation device 3 can be arranged outside the fire water tank 1. The electric heat tracing insulation device 3 is made by arranging insulation material outside the electric heat tracing insulation belt. The electric heat tracing insulation belt and the insulation material are made of conventional materials. The electric heat tracing insulation belt can use alloy resistance wire and insulation layer; the insulation material can use glass wool.
[0030] In order to accurately monitor the water temperature in the fire water tank 1, and can be opened according to the change of water temperature fire water tank heating device, preferably, the temperature control device comprises: temperature sensing part 2, which is set in the fire water tank 1 water surface above, for monitoring the water temperature in the fire water tank 1, and temperature control part 7, which is independently set in the fire water tank 1 outside, and the temperature sensing part 2 is communicated through the signal transmission line 8, for controlling the opening or closing of the fire water tank heating device. Temperature sensing part 2 is installed on the inner side wall of the fire water tank 1, and the temperature sensing probe is arranged at the lower end of the temperature sensing part 2. The above-mentioned temperature sensing probe is inserted into the water surface, which is used for detecting the water temperature in the fire water tank 1. The upper end of the temperature sensing probe is the main part of the temperature sensing part, and the main part is communicated with the temperature control part 7 through the signal transmission line 8, so as to monitor the water temperature in the fire water tank 1 in real time. The above-mentioned temperature sensing part 2 can timely transmit the temperature change to the temperature control part 7, and the temperature control part 7 opens or closes the fire water tank heating device according to the change of water temperature.
[0031] Preferably, the temperature control device further comprises: a valve 5, which is arranged on the water inlet pipe of the first warm air ring pipe 41 of the fire water tank heating device warm air ring pipe, for controlling the opening or closing of the warm air ring pipe 4. The above-mentioned valve 5 is an electric valve, which is communicated with the temperature control part 7 through the signal transmission line 8, so that the temperature control part 7 can directly control the opening or closing of the electric valve. The temperature control part 7, the valve 5, the temperature sensing part 2 and the electric heating and insulation device 3 are connected through the signal transmission line 8, so as to receive the temperature signal and send the instruction of opening or closing the electric heating and insulation device 3 and the valve 5.
[0032] When the temperature control part 7 fails to control, the above-mentioned valve 5 can be a manual valve, which is directly buried and leaks out of the ground, so as to facilitate personnel to close or open the valve 5, and also facilitates the connection with the temperature control part 7 and maintenance when used as an electric valve.
[0033] The specific use mode of the fire water tank insulation system is as follows:
[0034] 1) When low temperature weather appears in winter, the water surface temperature in the fire water tank 1 is constantly reduced, when the water surface temperature reaches the set fire water tank heating and heat preservation device starting temperature (the temperature is generally set at 5℃, the specific temperature setting can also be adjusted according to the actual situation), the temperature signal of the temperature sensing part 2 is sent to the temperature control device in the power distribution control cabinet 6 through the signal transmission line 8, and the valve 5 arranged on the water inlet pipe of the heating ring pipe 4 is started through the temperature control part 7. In the case that the heating ring pipe 4 arranged near the bottom of the fire water tank 1 is in the open state, the water surface temperature in the tank still cannot reach the set heat preservation device starting temperature in the case of extremely low temperature weather in winter, the temperature signal of the temperature sensing part 2 is sent to the temperature control part 7 in the power distribution control cabinet 6 through the signal transmission line 8, and the electric heat tracing heat preservation device 3 is started through the temperature control part 7, so as to realize double heat preservation of the fire water tank 1 and ensure that the water in the fire water tank 1 will not freeze.
[0035] 2) When the fire water tank heating and heat preservation device is in the working state, the water surface temperature in the fire water tank 1 is constantly increased, when the water surface temperature reaches the set fire water tank heating and heat preservation device closing temperature (the temperature is generally set at 10℃, the specific temperature setting can also be adjusted according to the actual situation), the temperature signal of the temperature sensing part 2 is sent to the temperature control part 7 in the power distribution control cabinet 6 through the signal transmission line 8, and the electric heat tracing heat preservation device 3 is closed through the temperature control part 7. In the case that the electric heat tracing heat preservation device 3 arranged outside the fire water tank is in the closed state, the water surface temperature in the tank still reaches the set heat preservation device closing temperature, the temperature signal of the temperature sensing part 2 is sent to the temperature control device in the power distribution control cabinet 6 through the signal transmission line 8, and the valve 5 arranged on the water inlet pipe of the heating ring pipe 4 is closed through the temperature control part 7, so as to realize automatic temperature control of the heat preservation system, reduce the consumption of electric energy and heat energy, and reduce the later operation cost of the oil depot.
[0036] 3) When special situations (such as damage of the signal transmission line 8, failure of the control elements in the power distribution control cabinet 6, power failure, etc.) occur, the power storage type sound and light alarm in the power distribution control cabinet 6 gives an alarm to remind the surrounding staff to handle the problem on site. According to different situations, the staff can manually open or close the electric heat tracing heat preservation device 3 in the power distribution control cabinet 6; the staff can manually open or close the heating ring pipe 4 on the ground.

[0038] In addition, it should be noted that various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, various possible combinations are not described again in the present application.
[0039] Furthermore, the various embodiments can also be combined with each other, as long as they do not contradict the idea of the present application, they should also be considered as disclosed in the present application.
