Description

[Technical field]

[0001] The utility model relates to the technical field of related equipment for protecting flammable solvents, in particular to a solvent security protection device. [Background technology]

[0002] There are great safety risks in the storage and transportation of flammable and explosive chemicals, solvents, and liquid fuels such as gasoline and diesel. To avoid high temperatures, anti-flammability measures must be taken. Safety measures and protective devices are essential in every link.

[0003] Existing protective measures for flammable and explosive liquids, such as gasoline, include but are not limited to: a bulkhead is provided in the transported tank, the two ends of the bulkhead are sealed and connected to the bottom and top of the tank respectively, the side wall of the bulkhead is sealed and connected to the side wall of the tank, the bulkhead divides the tank into two sealed cavities of the same size, each of which is provided with a wave-breaking plate, a drain pipe is provided at the bottom of the tank, and a bottom valve and a drain valve are provided on the drain pipe; a breathing valve and a refueling hole are provided at the top of the tank; a pressure sensor and a temperature sensor are provided in the cavity of the tank, and a display is installed at the top of the tank, and the display is connected to the pressure sensor and the temperature sensor at the same time. This structure can improve the safety of oil and gas transportation and monitor the oil and gas in the transportation state at all times, such as the content disclosed in patent CN201510854994.8, a method for ensuring the safety of gasoline engine travel. This is a very complex structural design, combined with the comprehensive management of multiple sensors in large transport tanks, and if a sensor fails or fails, it will also bring great safety risks.

[0004] Or as patent CN202022428607.3 discloses a fireproof battery device and electric vehicle, which discloses that the fireproof battery device includes a battery pack, an explosion-proof valve, and a cleaning device between the explosion-proof valve and the protective cover. The cleaning device can use liquid to cool down the battery pack when it gets out of control and sprays high-temperature smoke to the outside to prevent combustion. Liquid spraying is also used to cool down the battery electrolyte that may leak to prevent combustion. However, if a fire really starts, spraying water on the burning solvent is not a very safe strategy. Instead, it may cause the burning area to spread and the fire to expand. [Summary of the invention]

[0005] In view of the above problems, the utility model proposes a fire and combustion protection device with a self-driven and self-triggered reaction mechanism for flammable and explosive solvents and liquids. It is designed to solve the hidden dangers of combustion and explosion of flammable liquids when encountering open flames. By arranging a safety protection device in the container, as soon as a fire point appears, it can be extinguished immediately or the flammable conditions can be controlled so that it cannot continue to burn. In this way, the overall safety of the container or equipment containing flammable and explosive solutions can be effectively guaranteed.

[0006] The utility model relates to a solvent security protection device, which is specifically arranged in a container containing the solvent, and is characterized in that the security protection device comprises:

[0007] A number of flame retardant thermoplastic encapsulated monomers with fire extinguishing components encapsulated inside;

[0008] The flame retardant thermoplastic encapsulating monomer is laid on the entire liquid surface of the solvent in the container in an overlapping manner, and the flame retardant thermoplastic encapsulating monomer melts at a temperature above 100°C.

[0009] The overall average density of the flame retardant thermoplastic encapsulating monomer is less than the density of the solvent, so that the flame retardant thermoplastic encapsulating monomer is kept floating on the liquid surface of the solvent.

[0010] A hollow frame is provided inside the solvent container, the height of which is consistent with the liquid level. The flame-retardant thermoplastic encapsulation monomer is placed in the hollow frame and keeps in contact with the liquid surface of the solvent.

[0011] The total area converted from the number of the flame-retardant thermoplastic encapsulating monomers is sufficient to cover the solvent liquid surface area by 2 layers or more.

[0012] Furthermore, the flame-retardant thermoplastic packaging monomer is a hollow spherical, rectangular, square, circular or irregular three-dimensional sealing structure.

[0013] The size of the flame-retardant thermoplastic packaging monomer ranges from 10 mm to 200 mm.

[0014] When the flame-retardant thermoplastic encapsulating monomer floats on the surface of the solvent, its designed average density is designed to be within a numerical range of 50% to 80% of the density of the solvent.

[0015] The outer material of the flame-retardant thermoplastic packaging monomer is a flame-retardant thermoplastic material that is sealed hollow and filled with a fire extinguishing agent.

[0016] A foam fire extinguishing agent is poured into the flame retardant thermoplastic packaging monomer.

[0017] The flame retardant thermoplastic material is a flame retardant thermoplastic plastic with a melting temperature of 120° C. to 200° C., and the plastic itself is solvent resistant.

[0018] Furthermore, the flame retardant thermoplastic materials polyethylene and polypropylene have a melt index of 20-200, preferably 50-200.

[0019] The thickness of the outer material of the flame-retardant thermoplastic packaging monomer is 0.5 mm to 3 mm.

[0020] In the container to be protected, a small floating ball (diameter / size of 10-20mm) is placed to cover the surface of the solvent. The small floating ball (with any shape) is made of flame-retardant thermoplastic material and is hollow. A certain amount of fire extinguishing agent is poured inside. The fire extinguishing agent is preferably a foam fire extinguishing agent. The ratio of the amount of fire extinguishing agent filled to the remaining space inside the floating ball is controlled by controlling the average density of the small floating ball to 50% to 80% of the solvent density. This ensures that the small floating ball floats on the surface of the solution.

[0021] The fire extinguishing material encapsulates a monomer (summarizing the characteristics of a small floating ball), the outer material is a flame-retardant thermoplastic material, it is sealed hollow, the inside is filled with a fire extinguishing agent, and the overall density is lighter than a solvent.

[0022] The fire extinguishing material packaging monomer can also be ensured to be always placed on the surface of the solvent by other methods, and in this case, the overall density is not limited.

[0023] When the solvent is accidentally ignited by an external open flame, the small float made of flame-retardant thermoplastic material is subjected to high temperature. The surface plastic of the high-temperature self-melting fire-extinguishing plastic ice ball will melt rapidly at 130°C ~ 200°C (depending on the type of plastic used) under the action of heat, and the anti-solvent foam fire extinguishing agent loaded in the float will be quickly released, and a dense flame-retardant plastic layer and fire-extinguishing foam layer will quickly form on the surface of the solvent, which will quickly and automatically extinguish the open flame and isolate the solvent from the air to play a protective role.

[0024] The size of the high-temperature self-melting fire-extinguishing plastic small float can be selected according to the size of the liquid cooling equipment container. It is generally recommended to be 10mm~200mm. The wall thickness of the float is recommended to be 0.5m~3mm. It cannot be too thick to avoid melting too slowly and failing to release the foam fire extinguishing agent in the first time. Pour anti-soluble foam fire extinguishing agent into the float with a moderate amount. The design density of the small float can be in the numerical range of 50%~80% of the solvent density. The small float can float on the surface of the liquid to obtain the appropriate filling amount.

[0025] The plastic selected is a flame retardant thermoplastic that can be melted at 120℃ ~ 200℃, and the plastic itself is resistant to solvents.

[0026] Polyethylene and polypropylene are preferred, with a melt index of 1 to 1000, preferably a melt index of 50 to 200.

[0027] The solvent security protection device involved in the utility model is designed for inflammable and explosive solvents, liquid fuels, etc. When the liquid solvents and liquid fuels are burning, the combustion point can only exist at the interface between the liquid surface and the air, and they burn with the participation of oxygen. Therefore, the control point that needs to be controlled and extinguished is the entire liquid surface. A large number of flame-retardant thermoplastic packaging monomers with fire-extinguishing components encapsulated inside are used, which are arranged / floated on the liquid surface, and are covered on the liquid surface in multiple layers. Once the high temperature of the fire is encountered, the flame-retardant thermoplastic shell will instantly disintegrate, melt the flame-retardant plastic and release the internal foam fire-extinguishing components, instantly covering the fire point and extinguishing the fire point. The mechanism does not need to rely on power / signal / mechanical systems, and it will automatically trigger the reaction once the temperature exceeds the controllable range. It is safe, reliable, efficient, stable, and has low cost. It is also very simple and convenient to maintain and replenish it all year round, with low cost and strong practicality.

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] Embodiment 1:

[0034] Please refer to the attached Figure 1, which shows a solvent security protection device involved in the utility model, wherein a container 100 containing a solvent 10 is shown;

[0035] and a plurality of flame-retardant thermoplastic packaging monomers 200 with fire-extinguishing components encapsulated therein;

[0036] The flame retardant thermoplastic encapsulating monomer 200 is overlapped and laid on the entire liquid surface 11 of the solvent 10 in the container 100. The flame retardant thermoplastic encapsulating monomer melts at a temperature above 100°C.

[0037] The overall average density of the flame-retardant thermoplastic encapsulation monomer 200 is less than the density of the solvent, so that the flame-retardant thermoplastic encapsulation monomer 200 is kept floating on the liquid surface of the solvent.

[0038] The number of the flame retardant thermoplastic encapsulation monomers 200 is limited, and all of them can be spread out to completely cover the liquid surface, or even to cover two or more layers on the liquid surface. In terms of area, the shadow area of ​​the flame retardant thermoplastic encapsulation monomer is always enough to cover two or more layers of the liquid surface.

[0039] Furthermore, the flame retardant thermoplastic packaging monomer is a hollow spherical, rectangular, square, circular or irregular three-dimensional sealing structure. The structural elements thereof are required to be hollow, with a certain thickness of the outer layer and suitable for injecting fire extinguishing materials inside.

[0040] The size of the float ball can be selected according to the size of the liquid cooling device container. Generally speaking, the size of the flame-retardant thermoplastic packaging monomer ranges from 10 mm to 200 mm.

[0041] The flame retardant thermoplastic encapsulating monomer in Example 1 floats on the surface of the solvent, so its density is limited. When the flame retardant thermoplastic encapsulating monomer floats on the surface of the solvent, its designed average density is within the numerical range of 50% to 80% of the solvent density.

[0042] The outer material of the flame-retardant thermoplastic packaging monomer is a flame-retardant thermoplastic material that is sealed hollow and filled with a fire extinguishing agent.

[0043] A foam fire extinguishing agent is poured into the flame retardant thermoplastic packaging monomer.

[0044] The flame retardant thermoplastic material is a flame retardant thermoplastic plastic with a melting temperature of 120° C. to 200° C., and the plastic itself is solvent resistant.

[0045] Furthermore, the flame retardant thermoplastic materials polyethylene and polypropylene have a melt index of 20-200, preferably 50-200.

[0046] The thickness of the outer material of the flame-retardant thermoplastic encapsulation monomer is 0.5mm to 3mm. It should not be too thick, so as to avoid slow melting and failure to release the foam fire extinguishing agent immediately. The anti-soluble foam fire extinguishing agent is poured into the float ball with a moderate amount. The small float ball can float on the surface of the liquid with a specific gravity of 0.75, which is the appropriate amount of pouring.

[0047] The plastic is flame-retardant thermoplastic plastic that can be melted at 120°C to 200°C and is solvent-resistant, preferably polyethylene and polypropylene, with a melt index of 20 to 200, preferably 50 to 200.

[0048] In a container containing batteries and solvent, a small floating ball (diameter / size of 10-20 mm) is placed to cover the surface of the solvent. The small floating ball (with any shape) is made of flame-retardant thermoplastic material and is hollow. A certain amount of fire extinguishing agent is poured inside. The fire extinguishing agent is preferably a foam fire extinguishing agent. The ratio of the amount of fire extinguishing agent filled to the remaining space inside the floating ball is controlled by controlling the average density of the small floating ball to be 50% to 80% of the solvent density value.

[0049] The fire extinguishing material encapsulates a monomer (summarizing the characteristics of a small floating ball), the outer material is a flame-retardant thermoplastic material, it is sealed hollow, the inside is filled with a fire extinguishing agent, and the overall density is lighter than a solvent.

[0050] When the solvent is accidentally ignited by an external open flame, the small float made of flame-retardant thermoplastic material is subjected to high temperature. The surface plastic of the high-temperature self-melting fire-extinguishing plastic small float will quickly melt at 130℃~200℃ (depending on the type of plastic used) under the action of heat, and the anti-solvent foam fire extinguishing agent loaded in the float will be quickly released, and a dense flame-retardant plastic layer and fire-extinguishing foam layer will quickly form on the surface of the solvent, which will quickly and automatically extinguish the open flame, and isolate the solvent from the air to play a protective role.

[0051] Embodiment 2:

[0052] Please refer to the attached Figure 2 , which shows the structure diagram of Example 2. In this embodiment, other structural schemes are the same as those of Example 1, except that a liquid level hollow frame 300 is provided inside the solvent container 100, and the height of the liquid level hollow frame 300 is consistent with the liquid level, and the flame-retardant thermoplastic encapsulation monomer 200 is placed in the liquid level hollow frame 300, and the flame-retardant thermoplastic encapsulation monomer 200 is kept in contact with the liquid level of the solvent.

[0053] The solvent security protection device involved in the utility model is designed for flammable solvents. When the solvent burns, the combustion point can only exist at the interface between the liquid surface and the air, and it burns with the participation of oxygen. Therefore, the control point that needs to be controlled and extinguished is the entire liquid surface. A large number of flame-retardant thermoplastic packaging monomers with fire-extinguishing components encapsulated inside are used, which are arranged / floated on the liquid surface, and are covered on the liquid surface in multiple layers. Once the high temperature of the fire is encountered, the flame-retardant thermoplastic shell will instantly disintegrate, melt the flame-retardant plastic and release the internal foam fire-extinguishing components, instantly covering the fire point and extinguishing the fire point. The mechanism does not need to rely on power / signal / mechanical systems, and it will automatically trigger the reaction once the temperature exceeds the controllable range. It is safe, reliable, efficient, stable, and has low cost. It is also very simple and convenient to maintain and replenish it all year round, with low cost and strong practicality.
