Description

Technical Field

[0001] The invention relates to the technical field of barrier explosion suppression, and in particular to a non-metal barrier explosion suppression ball. Background Art

[0002] In recent years, with the development of national economy, inflammable and explosive liquids (gases) such as gasoline, liquefied gas, propane, etc. are more and more widely used in daily production and life. Usually, the inflammable and explosive liquids (gases) are stored in fuel tanks.

[0003] A fuel tank is a container for oil, specifically a device for storing fuel oil on a machine driven by a diesel or gasoline engine. Generally, the space above the liquid level of a fuel tank is filled with a flammable mixed gas. When there is a fire source, the fire source will ignite the mixed gas in the vicinity. If the combustion of the mixed gas is not restricted, it will spread rapidly. Due to ignition and flame propagation, an increasing pressure wave will be generated in front of the flame front. The pressure wave strongly compresses the unburned mixed gas, which will cause the tank to explode. The whole process takes only a few milliseconds.

[0004] Therefore, in the process of production, transportation, storage and use, combustion and explosion accidents are often caused by improper safety measures or accidents, which often cause significant property losses and casualties. Therefore, suppressing the fire and explosion of dangerous chemicals has attracted more and more attention.

[0005] AQ3001-2005 "Technical Requirements for Barrier Explosion-Proof Storage Tanks for Automobile Gas Stations, Light Fuel and LPG Tank Trucks" states: There should be no debris in the barrier explosion-proof material in the tank, otherwise it will affect the normal operation of the tank itself and the next step of the tank process. The internal crystallization of aluminum alloy explosion suppression materials is large, resulting in the material's brittleness, low elongation, poor anti-rust performance and other shortcomings, and it is easy to break and slag; in severe cases, it may even cause oil circuit blockage, resulting in the oil circuit ignition failure. During long-term immersion, the material is likely to affect the stability index (inducer, actual colloid), cleanliness index (solid particles) and water-soluble acid and alkali indicators of the oil, affecting the quality of the oil; the debris can block the oil gauge, causing it to be unable to rotate, and the oil volume cannot be accurately measured; in addition, the edge of the aluminum foil may crack, affecting the explosion suppression performance of the material.

[0006] Therefore, multiple explosion-proof balls can be filled into a container of flammable and explosive liquids, thereby dividing the inner cavity of the container into several "small chambers" or "cavities". These "small chambers" or "cavities" can effectively curb the spread of flames and sharply attenuate the explosion pressure wave; at the same time, the explosion-proof balls have a high surface efficiency per unit volume, and thus have good heat absorption, which can quickly absorb the heat released by combustion, reduce the temperature after the combustion reaction, reduce the expansion of the reaction gas, and increase the pressure value in the container slightly, so that the combustion speed does not reach the limit speed of the explosion. When the flammable and explosive liquid in the container is about to explode due to impact, high temperature, gunfire, artillery bombardment, etc., the explosion-proof balls can absorb and suppress the explosion energy, thereby eliminating the risk of explosion of the flammable and explosive liquid and achieving the purpose of explosion suppression.

[0007] Among them, non-metallic barrier explosion suppression balls usually have the following key parameters: (1) Duty cycle: refers to the percentage of the actual volume of all small balls to the volume of a container of a certain volume when the container is filled with explosion-proof small balls. This ratio should be as small as possible. The smaller the ratio, the smaller the reduction in container volume caused by the small balls, and the more liquid can be loaded. That is, in principle, under the premise of meeting the explosion-proof effect, the smaller the volume of the explosion-proof ball, the less volume is consumed; (2) Specific surface area: refers to the total surface area of ​​the small balls loaded in the container. The larger this area, the better; (3) Transparency at each angle: refers to the ratio of the light-transmitting area to the projection contour area after the small balls are projected at a certain angle. The smaller this ratio, the better. The smaller the ratio, the smaller the light-transmitting area.

[0008] In order to solve the above problems, patent application number 201210232080.4, patent name: a non-metallic barrier explosion suppression ball, which adopts non-metallic materials to replace metal materials.

This technical solution has a large volume, a small hole, and poor permeability, which affects the amount of liquid loaded into the container and the amount of liquid filled, and is also prone to form bubbles, which contain oxygen components and bring sufficient and necessary conditions for explosion, and cannot achieve the effect of safety and explosion-proof.

[0029] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0030] like Figure 1-Figure 4 As shown, in an embodiment of the present invention, a non-metallic barrier explosion-suppressing ball is provided, which is used to be filled in a container of flammable and explosive liquids, so as to absorb and suppress the explosion energy when the flammable and explosive liquids in the container are about to explode due to impact, high temperature, gunfire, artillery fire, etc., thereby eliminating the risk of explosion of the flammable and explosive liquids.

[0031] In an embodiment of the present invention, a non-metallic barrier explosion-suppressing ball includes: a North Pole column ring 1, a North latitude column ring 2, an equatorial ring 3, a South latitude column ring 4, an Antarctic column ring 7, a longitude main support plate 5, and a longitude auxiliary support plate 6. The North Pole column ring 1 is coaxial with the Antarctic column ring 7 and the size of the Antarctic column ring 7 is 1.1-1.2 times the size of the North Pole column ring 1. The North Pole column ring 1 is coaxial with the Antarctic column ring 7 and the size of the Antarctic column ring 7 is to reduce the permeability in the upper and lower directions, which is beneficial to hindering energy propagation and improving the flame retardant and explosion suppression effect. When the North Pole column ring 1 is coaxial with the Antarctic column ring 7 and the size of the Antarctic column ring 7 is 1.15 times the size of the North Pole column ring 1, the flame retardant and explosion suppression effect is best.

[0032] like Figure 1-Figure 4 As shown, in an embodiment of the present invention, the upper end of the longitude main support plate 5 is connected to the North Pole column ring 1 and the lower end is connected to the South Pole column ring 7, the longitude main support plate 5 is evenly distributed in a circular array with an axis coaxial with the North Pole column ring 1 and the South Pole column ring 7 as a reference, the longitude main support plate 5 is provided with a liquid flow hole 8, the longitude secondary support plate 6 is a plurality of plates, and one longitude secondary support plate 6 is arranged between each two adjacent longitude main support plates 5, the secondary support plate 6 is a bow-shaped plate without holes, which is mainly used to hinder energy transmission and improve the flame retardant and explosion suppression effects.

[0033] like Figure 1-Figure 4 As shown, in an embodiment of the present invention, the equatorial ring 3 intersects and is perpendicular to the longitude main support plate 5, and is used to bisect the non-metallic barrier explosion suppression ball. The equatorial ring 3 is an annular plate, and the equatorial ring 3 can also be an annular wave plate.

[0034] like Figure 1-Figure 4As shown, in an embodiment of the present invention, a north latitude column ring 2 is arranged to the north of the equatorial ring 3, and a south latitude column ring 4 is arranged to the south of the equatorial ring 3. The sizes of the north latitude column ring 3 and the south latitude column ring 4 are different, which are used to improve the permeability of the non-metallic barrier explosion suppression ball.

[0035] like Figure 1-Figure 4 As shown, in the embodiment of the present invention, the longitudinal main support sheet 6 is an arcuate thin sheet with a "U"-shaped liquid circulation hole 8 opened thereon to facilitate the circulation of the liquid.

[0036] like Figure 1-Figure 4 As shown, in an embodiment of the present invention, the liquid circulation hole includes a top 81, a support end 1 82 and a support end 2 83, and the top 81 of the liquid circulation hole exceeds the height of the north latitude column ring 2.

[0037] like Figure 1-Figure 4 As shown, in an embodiment of the present invention, the Antarctic column ring 7 and the south latitude column ring 4 are connected by reinforcing ribs 9, and looking down from the North Pole column ring 1 toward the Antarctic column ring 7, the projections of the longitude main support plate 5 and the longitude secondary support plate 6 do not overlap with the reinforcing ribs 9, and the reinforcing ribs 9 include full-width reinforcing ribs 91 and half-width reinforcing ribs 92, and a half-width reinforcing rib 92 is arranged between every two adjacent full-width reinforcing ribs 91, and the half-width reinforcing ribs 92 increase the fluidity of the liquid, and the full-width reinforcing ribs 91 hinder the propagation of energy.

[0038] like Figure 1-Figure 4 As shown, in an embodiment of the present invention, the south pole column ring 7 is connected to the support end 1 82 of the liquid circulation hole 8, and the south latitude column ring 4 is connected to the support end 2 83 of the liquid circulation hole 8.

[0039] like Figure 1-Figure 4 As shown, in an embodiment of the present invention, one end of the longitude auxiliary support piece 6 is connected to the north latitude column ring 2, and the other end of the longitude auxiliary support piece 6 is connected to the south latitude column ring 4.

[0040] like Figure 1-Figure 4 As shown, in an embodiment of the present invention, a support frame 11 is further provided on the North Pole column ring, and the support frame 11 is used to block the liquid surging from the direction of the South Pole column ring 7. The support frame is in a cross shape and forms a plurality of holes with the North Pole column ring 1 for circulating liquid.

[0041] like Figure 1-Figure 4 As shown, in an embodiment of the present invention, looking down from the direction of the North Pole column ring 1 toward the direction of the South Pole column ring 7, the North Pole column ring 1, the North latitude column ring 2, the equatorial ring 3, the South latitude column ring 4, and the South Pole column ring 7 are not on the same projection plane.

[0042] like Figure 5-Figure 7 As shown, in an embodiment of the present invention, the working principle of the non-metallic barrier explosion-suppressing balls in the container is as follows: the container is filled with non-metallic barrier explosion-suppressing balls, and as few non-metallic barrier explosion-suppressing balls as possible are filled into the container to form a complex spatial maze structure (connected to each other and without closed areas), and the maze walls are used to block energy propagation and absorb energy. Semi-enclosed areas must be avoided. The formation of bubbles will make the presence of oxygen more likely to explode, and will also cause less liquid to be loaded.

[0043] When liquid flows from the north latitude column ring 2 of a non-metallic barrier explosion-suppression ball to the Antarctic column ring 7, the longitude main support plate 5 divides the flowing energy into several parts. When flowing through the longitude auxiliary support plate 6, the energy is further subdivided and weakened. When it reaches the equatorial ring 3, due to the blocking effect of the equatorial ring 3, the energy is divided into two parts, one part flows to other non-metallic barrier explosion-suppression balls, and the other part enters the inside of the sphere and flows to the Antarctic column ring 7. The reinforcing ribs 9 on the Antarctic column ring 7 will further cut and divert the energy to other small balls, repeating the energy blocking and decomposition work to achieve explosion-proof function.

[0044] When liquid enters the interior of a non-metallic barrier explosion-suppressing sphere from the equatorial ring 3 direction (east-west direction) of a non-metallic barrier explosion-suppressing sphere, since the longitude main support plates 5 and longitude auxiliary support plates 6 are arranged in a circular array, there is an angle between each two adjacent longitude main support plates 5 and longitude auxiliary support plates 6, which will block part of the energy of the liquid. At the same time, the north latitude column ring 2 and the south latitude column ring 4 will also block the flow of liquid, reduce the spread of energy, and achieve explosion prevention.

[0045] When liquid flows from the south pole column ring 7 of a non-metallic barrier explosion suppression ball to the north pole column ring 1, the support frame 9 on the north pole column ring 1 divides the energy to achieve an explosion-proof function.

[0046] When looking down from the direction of the North Pole column ring 1 toward the South Pole column ring, the North Pole column ring 1, the North Latitude column ring 2, the Equatorial ring 3, the South Latitude column ring 4, and the South Pole column ring 7 are not on the same projection plane and are also not on the same projection plane as the reinforcement ribs 9 of the South Pole ring 7. Therefore, every bit of energy transmitted by the liquid can be cut and blocked to achieve explosion protection.

[0047] like Figure 5-Figure 7 As shown, in the embodiment of the present invention, the non-metallic barrier explosion suppression ball is transparent and has a small mass, so it has a very low volume occupancy in the container, and more liquid can be placed in the box with the same volume.
