Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fire extinguishing of wine storage tanks, and more particularly relates to a wine storage tank with fire extinguishing and fireproof functions. BACKGROUND

[0002] A wine storage tank is a container for storing wine in a distillery and is usually a tank body made of stainless steel. The wine storage tank has different sizes, and the storage capacity of a large wine storage tank can reach hundreds of tons, and the storage capacity of a small wine storage tank can also reach several tons. The liquor in the wine storage tank is a flammable and explosive product. During daily storage, ethanol vapor will accumulate on the top of the wine storage tank, and when the ethanol vapor concentration exceeds the limit value, it is easy to explode. When the top of the tank body of the wine storage tank is struck by lightning, impacted or subjected to illegal welding operation, the ethanol vapor or liquor inside the tank body may be ignited, causing the liquor in the wine storage tank to catch fire.

[0003] In actual disposal of liquor fire, because ethanol can be mixed with water in any proportion, water cannot be used to extinguish the fire, and common water cannot be used to extinguish the liquor fire. Therefore, in the prior art, the disposal method of the fire brigade for the fire of an outdoor metal wine tank is to spray water on the outer wall of the wine tank while spraying fire extinguishing foam into the tank to cover and suffocate. If the liquor leaks to the outside, the corresponding fire extinguishing according to the flow fire disposal method is required. Through the above-mentioned fire extinguishing method, although the spread of the fire is prevented and the on-site hidden danger is eliminated, due to the mixing of the foam extinguishing agent and the stored liquor in the tank, the stored liquor in the tank is not burned, but still loses its practical value and can only be abandoned, which causes great loss to the distillery. CONTENT OF THE INVENTION

[0004] Based on the above technical problems, the application provides a wine storage tank with fire extinguishing and fireproof functions to solve the technical problem that the remaining liquor in the tank is abandoned in the prior art by using the foam extinguishing method.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the application is to provide a wine storage tank with fire extinguishing and fireproof functions, which comprises: a tank body having an accommodating cavity inside, wherein the top of the tank body is provided with an exhaust valve, and the exhaust valve is in communication with the accommodating cavity; a temperature detection element arranged in the accommodating cavity and arranged above the liquid level in the accommodating cavity; and The fire extinguishing assembly comprises a first exhaust pipe and a fire extinguishing gas storage device, the fire extinguishing gas storage device is arranged outside the tank body, the first exhaust pipe has at least two gas inlet ends and at least one gas outlet end, the gas outlet end of the first exhaust pipe is arranged in the containing cavity and is arranged below the liquid level in the containing cavity, one of the gas inlet ends of the first exhaust pipe is connected with the fire extinguishing gas storage device after penetrating through the side wall of the tank body, and the other gas inlet end of the first exhaust pipe is connected with a gas inlet valve group after penetrating through the side wall of the tank body.

[0006] In a possible implementation, the wine storage tank with fire extinguishing and fire prevention functions further comprises: An ethanol vapor concentration detection element is arranged in the containing cavity and is arranged above the liquid level in the containing cavity, and is used for detecting the ethanol vapor concentration in the containing cavity; and A second exhaust pipe is in communication with the containing cavity above the liquid level at one end and is in communication with the fire extinguishing gas storage device at the other end, and is used for injecting fire extinguishing gas above the liquid level, the density of the fire extinguishing gas being greater than the density of ethanol vapor.

[0007] In a possible implementation, the end of the second exhaust pipe in communication with the fire extinguishing gas storage device is provided with a first gas inlet check valve.

[0008] In a possible implementation, the gas outlet end of the first exhaust pipe has a plurality of gas outlet holes.

[0009] In a possible implementation, the gas outlet end of the first exhaust pipe is arranged in the containing cavity in a horizontal spiral winding manner and is provided with a plurality of gas outlet holes spaced apart along the winding direction of the gas outlet end.

[0010] In a possible implementation, the gas inlet valve group comprises: A second gas inlet check valve is connected with the corresponding gas inlet end of the first exhaust pipe; A gas path on-off valve is arranged at the end of the second gas inlet check valve away from the first exhaust pipe; and A gas inlet connector is arranged at the end of the gas path on-off valve away from the second gas inlet check valve.

[0011] In a possible implementation, the fire extinguishing gas storage device comprises: A gas storage tank for storing fire extinguishing gas; and A pressure reducing valve is arranged at the gas outlet end of the gas storage tank, and the corresponding gas inlet end of the first exhaust pipe is used for being connected with the pressure reducing valve.

[0012] In a possible implementation, the tank body further comprises a liquid level meter arranged in the containing cavity.

[0013] In one possible implementation, the wine storage tank with fire extinguishing and fire prevention functions further includes a mobile gas fire extinguishing device, the outlet of which is detachably connected to the inlet valve assembly.

[0014] In one possible implementation, the fire extinguishing gas storage device is used to store either compressed nitrogen or compressed carbon dioxide.

[0015] Compared with existing technologies, the beneficial effects of the wine storage tank with fire extinguishing and fire prevention functions provided in this application are: The wine storage tank with fire extinguishing and fire prevention functions provided in this application includes a tank body, a temperature detection element, and a fire extinguishing assembly. The tank body has an internal cavity for storing the wine, and an exhaust valve at the top of the cavity for venting, maintaining pressure balance within the tank. The temperature detection element monitors the temperature at the top of the cavity. When the wine inside the tank catches fire, the temperature detection element can detect the fire promptly based on temperature changes. The fire extinguishing assembly includes a fire extinguishing gas storage device and a first exhaust pipe. When a fire breaks out inside the tank, the fire extinguishing gas storage device delivers gases such as carbon dioxide and nitrogen into the tank through the first exhaust pipe, isolating the wine from the air and thus mitigating or extinguishing the fire. Since the ethanol in the wine will evaporate, producing ethanol vapor, which is a flammable and explosive gas, the fire extinguishing gas entering the cavity can expel the ethanol vapor to the outside, achieving fire prevention.

[0016] This application utilizes a temperature detection element to monitor the temperature at the top of the container in real time, enabling timely detection of any fire in the liquor and facilitating prompt firefighting measures at the winery. During firefighting, before firefighters arrive, fire extinguishing gas can be supplied to the container using a gas storage device and a first exhaust pipe. The rising gas, above the liquor surface, isolates the air and liquor, mitigating the fire or even extinguishing it. Once the gas storage device is depleted, a mobile gas fire extinguishing device or an arriving fire truck can be connected to the other inlet of the first exhaust pipe to continue supplying fire extinguishing gas to the container. Compared to foam firefighting, carbon dioxide or nitrogen fire extinguishing does not contaminate the liquor, helping to reduce losses for the winery. Attached Figure Description

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0024] Please refer to the following: Figures 1 to 5 The following describes the wine storage tank with fire extinguishing and fire prevention functions provided in the embodiments of this application.

[0025] Please see Figure 1 and Figure 2 This application provides a wine storage tank with fire extinguishing and fire prevention functions, including a tank body 10, a temperature detection element 20, and a fire extinguishing assembly 30. The tank body 10 has an internal receiving cavity, and an exhaust valve 11 is provided at the top of the tank body 10, which communicates with the receiving cavity. The temperature detection element 20 is located inside the receiving cavity and is positioned above the liquid level in the receiving cavity. The fire extinguishing assembly 30 includes a first exhaust pipe 31 and a fire extinguishing gas storage device 32. The fire extinguishing gas storage device 32 is located outside the tank body 10. The first exhaust pipe 31 has at least two air inlets and at least one exhaust outlet. The exhaust outlet of the first exhaust pipe 31 is located inside the receiving cavity and is positioned below the liquid level in the receiving cavity. One air inlet of the first exhaust pipe 31 penetrates the side wall of the tank body 10 and is connected to the fire extinguishing gas storage device 32. The other air inlet of the first exhaust pipe 31 penetrates the side wall of the tank body 10 and is connected to an air inlet valve assembly 312.

[0026] Compared with the prior art, the beneficial effects of the wine storage tank with fire extinguishing and fire prevention functions provided in this application embodiment are: The wine storage tank with fire extinguishing and fire prevention functions provided in this application embodiment includes a tank body 10, a temperature detection element 20, and a fire extinguishing assembly 30. The tank body 10 has an internal cavity for storing wine, and an exhaust valve 11 is provided at the top of the cavity for venting, so as to balance the internal pressure of the tank body 10. The temperature detection element 20 is used to detect the temperature at the top of the cavity. When the wine inside the tank body 10 catches fire, the temperature detection element 20 can detect it in time according to the temperature change. The fire extinguishing assembly 30 includes a fire extinguishing gas storage device 32 and a first exhaust pipe 31. When a fire occurs inside the wine tank, the fire extinguishing gas storage device 32 delivers gases such as carbon dioxide and nitrogen into the wine tank through the first exhaust pipe 31, isolating the wine from the air, thereby mitigating or extinguishing the fire.

[0027] This embodiment uses a temperature detection element 20 to monitor the temperature at the top of the container in real time, enabling timely detection of any fire in the liquor and facilitating prompt firefighting measures by the winery. During firefighting, before firefighters arrive, fire extinguishing gas can be supplied to the container using the fire extinguishing gas storage device 32 and the first exhaust pipe 31. The rising fire extinguishing gas above the liquor surface isolates the air and liquor, mitigating the fire or even extinguishing it completely. Compared to foam firefighting, carbon dioxide or nitrogen fire extinguishing does not contaminate the liquor, helping to reduce losses for the winery.

[0028] The wine storage tank with fire extinguishing and fire prevention functions provided by this utility model can effectively extinguish fires in wine tanks while ensuring that the quality of the wine remains unchanged, thus reducing losses for wineries. It should be noted that when using carbon dioxide for fire extinguishing, even if a small amount of carbon dioxide may dissolve into the wine during the extinguishing process, causing an increase in acidity, this small amount of carbon dioxide can be eliminated through subsequent physical processes, without affecting the final quality of the wine. When using less soluble gases such as nitrogen as the extinguishing gas, the acidity of the wine will not increase.

[0029] Tank 10 is used to store the liquor. It is typically made of stainless steel and has a diameter ranging from tens of centimeters to several meters. The appropriate tank volume is selected based on the required storage volume. An vent valve 11 is installed on the top of tank 10, and a level gauge is installed inside to detect the liquor level. The vent valve 11 ensures pressure balance within the storage chamber, preventing excessive pressure buildup due to ethanol evaporation. The level gauge can be an electronic level gauge, capable of real-time monitoring of the liquor level.

[0030] If the liquid inside the storage tank catches fire, it will burn above the liquid surface. To ensure timely detection of the fire, a temperature detection element 20 is installed inside the storage cavity. The temperature detection element 20 is specifically a temperature sensor that can monitor the internal temperature of the storage cavity in real time. The temperature detection element 20 is connected to the winery's maintenance room or controller. When an abnormal temperature is detected (such as rising to hundreds of degrees Celsius), the winery's maintenance room or controller will receive a signal, thereby promptly activating the fire extinguishing assembly 30 to extinguish the fire.

[0031] Temperature sensing element 20, exhaust valve 11 and level gauge are common components on wine storage tanks and are mature products already available on the market. Users can directly purchase products of appropriate specifications and models and apply them. Their specific structure, working principle and usage will not be described in detail.

[0032] The fire extinguishing assembly 30 includes a first exhaust pipe 31 and a fire extinguishing gas storage device 32. The fire extinguishing gas storage device 32 stores compressed nitrogen, compressed carbon dioxide, or other inert gases that can extinguish fires involving alcoholic beverages. The first exhaust pipe 31 connects the outlet of the fire extinguishing gas storage device 32 to the interior of the storage chamber. The first exhaust pipe 31 can be made of stainless steel, which does not react with the alcoholic beverage and will not affect its quality. When a fire occurs in the storage tank, the valve of the fire extinguishing gas storage device 32 is opened, and compressed gas is delivered to the interior of the storage chamber through the first exhaust pipe 31, displacing the air in the chamber and thus mitigating the fire or even extinguishing it directly.

[0033] The fire extinguishing component 30 can be placed near the tank 10 or at a distance from the tank 10, as long as the gas can be delivered smoothly.

[0034] The first exhaust pipe 31 is located below the liquid surface, specifically at the bottom or middle of the containment cavity. Fire extinguishing gas introduced into the containment cavity can float to the surface and extinguish the fire. The first exhaust pipe 31 has at least two inlets and at least one outlet. The outlet only needs to ensure that the fire extinguishing gas can be delivered into the containment cavity; one or more outlets can be provided. At least two inlets should be provided, one of which is connected to the fire extinguishing gas storage device 32. This allows for the immediate delivery of fire extinguishing gas upon detection of a fire, enabling control or even extinguishing of the fire before the arrival of a fire truck. The other one or more inlets are equipped with an inlet valve assembly 312, which can connect to a mobile gas fire extinguishing device 60 or an arriving fire truck after the fire extinguishing gas storage device 32 has been depleted.

[0035] Because ethanol is volatile, to prevent the volatile ethanol vapors from accumulating at the top of the containment cavity and causing a deflagration, please refer to [the relevant documentation / reference]. Figure 2 and Figure 4 In some possible embodiments, the wine storage tank with fire extinguishing and fire prevention functions also includes an ethanol vapor concentration detection element 40 and a second exhaust pipe 50. The ethanol vapor concentration detection element 40 is located in the containment cavity and is positioned above the liquid level in the containment cavity. One end of the second exhaust pipe 50 is connected to the position of the containment cavity above the liquid level, and the other end is connected to the fire extinguishing gas storage device 32.

[0036] In this embodiment, an ethanol vapor concentration detection element 40 is provided at the top of the containment cavity, and the outlet of the fire extinguishing gas storage device 32 is also connected to the top of the containment cavity through a second exhaust pipe 50 for injecting fire extinguishing gas above the liquid surface. The density of the fire extinguishing gas is greater than the density of ethanol vapor.

[0037] When the ethanol vapor concentration detection element 40 detects that the ethanol vapor concentration has reached the critical concentration that makes it easy to explode, it can deliver carbon dioxide or nitrogen gas to the top of the containment cavity through the second exhaust pipe 50, and squeeze out the volatilized ethanol vapor through the exhaust valve 11, thereby eliminating the fire hazard and achieving the purpose of fire safety.

[0038] Please see Figure 1 , Figure 2 and Figure 4 In some possible embodiments, the end of the second exhaust pipe 50 that is connected to the fire extinguishing gas storage device 32 is provided with a first air inlet check valve 51, which can prevent the liquid from flowing back through the second exhaust pipe 50.

[0039] Both the ethanol vapor concentration detection element 40 and the first inlet check valve 51 are mature products in the existing technology. Users only need to select the appropriate specifications and models for use. Since both the ethanol vapor concentration detection element 40 and the temperature detection element 20 are electronic components, in order to prevent their failure, personnel can be arranged to perform regular maintenance and replace them in a timely manner when a fault occurs.

[0040] Please see Figure 3 and Figure 5 In some possible embodiments, in order to make the fire extinguishing gas evenly distributed, the outlet end of the first exhaust pipe 31 has multiple outlet holes 311 distributed at different positions, which can make the fire extinguishing gas more evenly distributed in the tank 10, thereby improving the fire extinguishing efficiency and effect.

[0041] Please see Figure 3 and Figure 5 In some possible embodiments, the outlet end of the first exhaust pipe 31 is a horizontally arranged coil, which is arranged in a horizontal spiral coil in the receiving cavity, and multiple air outlets 311 are spaced apart along its own coiling direction. The air outlets 311 are arranged facing upwards, and multiple air outlets 311 can release air at the same time, so that the fire extinguishing gas is evenly distributed in the tank.

[0042] This application can modify the existing wine tank structure by adding a first exhaust pipe 31 and related pipes and valves to the bottom of the tank body 10, and adding a second exhaust pipe 50 and related pipes and valves to the top of the tank body 10, so as to facilitate the injection of fire extinguishing gas.

[0043] The shape and structure of the first exhaust pipe 31 at the bottom helps the fire extinguishing gas to disperse, ensuring that the injected fire extinguishing gas can rise evenly from the bottom to the top of the tank, ensuring that the fire extinguishing gas acts on the entire surface of the burning liquid, and extinguishing the fire through the principle of suffocation.

[0044] Please see Figure 1 and Figure 5In some possible embodiments, the intake valve assembly 312 includes a second intake check valve 3121, an air path switching valve 3122, and an intake connector 3123. The second intake check valve 3121 is connected to the intake end corresponding to the first exhaust pipe 31; the air path switching valve 3122 is located at the end of the second intake check valve 3121 away from the first exhaust pipe 31; and the intake connector 3123 is located at the end of the air path switching valve 3122 away from the second intake check valve 3121.

[0045] The air intake valve assembly 312 includes a first air intake check valve 51, a gas circuit switching valve 3122, and an air intake connector 3123. The air intake connector 3123 is used to connect to the extinguishing gas source on the mobile gas extinguishing device 60 or a fire truck. The gas circuit switching valve 3122 is used to control the opening and closing of the gas circuit. The gas circuit switching valve 3122 can be a manual valve or an electrically controlled valve. The second air intake check valve 3121 has the same structure as the first air intake check valve 51 and its function is to prevent gas backflow and liquid leakage.

[0046] Please see Figure 1 , Figure 2 and Figure 4 In some possible embodiments, the fire extinguishing gas storage device 32 includes a gas storage tank 321 and a pressure reducing valve 322. The gas storage tank 321 is used to store fire extinguishing gas; the pressure reducing valve 322 is located at the outlet end of the gas storage tank 321, and the inlet end of the first exhaust pipe 31 is used to connect to the pressure reducing valve 322.

[0047] The gas storage tank 321 stores fire extinguishing gases such as compressed carbon dioxide and compressed nitrogen. In order to prevent excessive gas pressure from damaging the first exhaust pipe 31 or the second exhaust pipe 50, the gas needs to be reduced in pressure by the pressure reducing valve 322 before being delivered.

[0048] The pressure reducing valve 322, as well as the aforementioned second air inlet check valve 3121, air circuit switch valve 3122, and air inlet connector 3123, are all products already available on the market. There are no restrictions on their specific specifications and models, and users can choose to install them according to their actual needs.

[0049] Please see Figure 1 , Figure 4 and Figure 5 In some possible embodiments, the wine storage tank with fire extinguishing and fire prevention functions also includes a portable gas fire extinguishing device 60, the outlet of which is detachably connected to the inlet valve assembly 312. The portable gas fire extinguishing device 60 can be a portable carbon dioxide fire extinguisher, which can be connected to the inlet connector 3123 of the inlet valve assembly 312 to deliver fire extinguishing gas into the tank 10.

[0050] The wine storage tank with fire extinguishing and fire prevention functions provided in this application has the following three methods of fire extinguishing gas injection during operation: The temperature detection element 20 detects whether a fire has occurred. Upon detection, the controller automatically opens the air intake valve assembly 312 to automatically introduce air, nipping the fire hazard in the bud. If the valve fails to open in time due to a malfunction or other factors, manual air intake can be achieved by opening the relevant valves and pipelines. When the gas in the extinguishing gas storage device 32 is depleted, the air intake valve assembly 312 can be connected to the mobile gas extinguishing device 60 or the extinguishing gas interface of a fire truck for external injection of extinguishing gas, providing more possibilities for handling alcohol fires.

[0051] Since the cost of common fire extinguishing gases (such as carbon dioxide and nitrogen) is lower than that of foam fire extinguishing agents, and there are local manufacturers or enterprises that specialize in producing and supplying these fire extinguishing gases, the replenishment of fire extinguishing gases is more flexible, faster, and more abundant than the replenishment of foam fire extinguishing agents, and the cost of use is lower.

[0052] The wine storage tank with fire extinguishing and fire prevention functions provided in this application is suitable for use in the event of an internal fire. Even if the wine leaks to the outside and catches fire, it can still be extinguished with foam extinguishing agents. External fire may ignite the internal wine by heating the tank body 10. In this case, the fire inside the tank body 10 can be extinguished by the fire extinguishing component 30.

[0053] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
