Detailed Description of the Invention

[0001] [Cross - Reference to Related Applications] This application claims the benefit of Chinese Patent Applications 202111121577.4, 202111123395.0, 202111121576.X, and 202111123543.9, filed on September 24, 2021, the contents of which are incorporated herein by reference.

[0002] [Technical Field] The present invention relates to the technical field of fire prevention and explosion protection, and specifically to a particle - type flame arrester that automatically eliminates defects in the fire - prevention part.

[0003] [Background Art] With the further strictness of environmental protection standards, various chemical companies have begun to implement large - scale collection and treatment of VOCs in oil storage systems. A method of integrally connecting a plurality of storage tanks in a tank area or the storage tanks of the entire factory with a gas - phase communication pipeline to intensively collect and treat VOCs has been adopted. After the gas - phase communication of the storage tanks, if a fire occurs in a single tank, the flame will spread through the gas - phase communication pipeline, resulting in a serious risk of fire occurring in the tank group. Therefore, the requirements for fire - prevention and explosion - protection technologies between complex pipelines have increased. Currently, as a protection means for pipelines that connect storage tanks in gas - phase communication, the installation of a flame arrester has become the mainstream, and among them, the most commonly used is the crimp ribbon type flame arrester. The crimp ribbon type flame arrester is usually installed at the upper part of the tank, near the combustion equipment or other places, so it is inconvenient to detach and attach. In addition, the existing crimp ribbon type flame arresters are prone to clogging and difficult to clean, which affects the operation of the process. Furthermore, especially for large - scale crimp ribbon type flame arresters, the flame arrester plate is easily blown away by the impact of detonations, resulting in defects and loss of function, making it unusable.

[0004] [Summary of the Invention] [Problems to be Solved by the Invention] The object of the present invention is to automatically eliminate defects in the fire prevention part when the flame arrester is deformed due to the impact of an explosion, continuously and normally exert the effects of preventing the spread of fire and explosion, be less likely to clog, be easy to attach and detach, and be easy to clean. Defense To provide a flame arrester capable of automatically eliminating defects in the fire part.

[0005] 〔Means for Solving the Problem〕 To achieve the above object, the present invention includes a fire prevention Part which includes a fire prevention Part having a fire prevention Part case, and the fire prevention Part case is a hollow one with fire prevention Part openings formed at both ends respectively. Two blocking parts are provided at the fire prevention Part openings, a fire prevention chamber is defined between the two blocking parts, a plurality of openings are formed in the blocking parts, and fire prevention particles are filled in the fire prevention chamber. Defense A flame arrester capable of automatically eliminating defects in the fire part, wherein the fire prevention Part further includes a fire prevention particle replenishment structure configured to automatically fill fire prevention particles into the fire prevention chamber when a gap occurs in the fire prevention chamber. Defense Provided is a flame arrester capable of automatically eliminating defects in the fire part. In a preferred form, the fire prevention particle replenishment structure includes a replenishment port formed in the fire prevention Part case, a replenishment cylinder extending outward from the edge of the replenishment port, a replenishment chamber formed in the replenishment cylinder and communicating with the fire prevention chamber, and a piston part and a spring provided in the replenishment chamber. The spring elastically biases the piston part in the direction toward the fire prevention chamber, and a gap is formed between the outer edge of the piston part and the inner wall of the replenishment cylinder to enable the piston part to move in the replenishment chamber toward the fire prevention chamber.

[0006] Preferably, from one of the fire prevention Part openings to the other fire prevention PartAlong the direction towards the opening, the fire prevention chamber includes at least two compartments, the particle size of the fire prevention particles filled in the first compartment is larger than that of the fire prevention particles filled in the second compartment, and in the defect automatically eliminable frame arrester of the fire prevention part, at least one fire prevention particle replenishment structure is included for each compartment.

[0007] Preferably, for fire prevention Part A first case and a second case are respectively connected to both ends of the fire prevention case. The first case and the second case are each formed with an inner opening on the side facing each other, and an inner connection flange extending outward from the edge of the inner opening is formed. The defect automatically eliminable frame arrester of the fire prevention part further includes a connection part, and both ends of the connection part are respectively connected to the inner connection flange of the first case and the inner connection flange of the second case. The fire prevention Part is interposed between the first case and the second case.

[0008] Preferably, the fire prevention Part further includes a fire prevention particle exchange structure. The fire prevention particle exchange structure includes a fire prevention particle discharge port and a fire prevention particle replenishment port. The fire prevention particle discharge port is formed at the bottom of the fire prevention Part case, and the fire prevention particle replenishment port is formed at the top of the fire prevention Part case, and the fire prevention Part includes a discharge valve for controlling the opening and closing of the fire prevention particle discharge port and a replenishment valve for controlling the opening and closing of the fire prevention particle replenishment port.

[0009] 〔Advantages of the Invention〕 The defect automatically eliminable frame arrester of the fire prevention part according to the present invention has a simple structure, and particulate fire prevention materials are used for fire prevention Part The particulate fire prevention materials have the advantages of large relative surface area, large heat exchange area, easy heat conduction, excellent fire prevention performance, and being difficult to clog and easy to clean, which are given to the fire prevention Part itself. Furthermore, the fire prevention of the present invention PartIt further includes a fireproof particle replenishment structure. When filling the fireproof particles, after the fireproof chamber is filled with the fireproof particles, the fireproof particles enter the replenishment chamber, hit the piston part and move to the outside of the fireproof chamber, compressing the spring. When the defect-automatic-eliminating frame arrester of the fireproof part is used normally, the spring always remains in the compressed state, and the fireproof particles in the replenishment chamber are retained in the replenishment chamber. When the defect-automatic-eliminating frame arrester of the fireproof part is impacted by an explosion, the fireproof particles in the fireproof chamber become denser. Also, the blocking part may be deformed by the impact. In this case, a certain gap is generated in the fireproof chamber (the part at the top). At this time, due to the biasing force of the spring in the compressed state, the piston part moves along the extending direction of the replenishment chamber, pushing the fireproof particles in the replenishment chamber into the fireproof chamber, filling the gap generated in the fireproof chamber again, and filling the fireproof chamber with the fireproof particles, thereby avoiding the occurrence of defects (gaps) in the frame arrester and the loss of fireproof ability. Therefore, when the defect-automatic-eliminating frame arrester of the fireproof part of the present invention is deformed due to the impact of an explosion, it can automatically eliminate the defects of the fireproof part and continue to normally exert the effects of preventing fire spread and explosion protection.

[0010] 〔Embodiments for Carrying out the Invention〕 It should be noted that the embodiments in the present invention and the features in the embodiments may be combined with each other without contradiction.

[0011] In the present invention, the orientation or positional relationship indicated by terms such as "opposite", "facing", "circumferential direction", "axial direction", etc. is based on the orientation or positional relationship shown in the drawings, and it should also be understood that it corresponds to the actual orientation or positional relationship used. "Inside and outside" means inside and outside with respect to the contour of each member itself, and does not indicate that such a device or component must have a specific orientation or be configured and operate in a specific orientation, so it cannot be understood as a limitation of the present invention.

[0012] Hereinafter, with reference to the drawings, the present invention will be described in detail in combination with embodiments.

[0013] As shown in FIGS. 1 to 3, the present invention provides a frame arrester that automatically eliminates defects in a fireproof part. The frame arrester includes a first case 1, a second case 2, and a fireproof Part 4 located between the first case 1 and the second case 2. The fireproof Part 4 has a fireproof Part case 19. The fireproof Part case 19 is hollow and has two fireproof Part openings facing the first case 1 and the second case 2 respectively. The fireproof Part 4 further includes two blocking parts provided in the two fireproof Part openings respectively. A fireproof chamber 5 is defined between the two blocking parts. A plurality of openings are formed in the blocking parts, and the fireproof chamber 5 is filled with fireproof particles. The fireproof Part 4 further includes a fireproof particle replenishment structure. The fireproof particle replenishment structure includes a replenishment port 18, a replenishment cylinder 20, a replenishment chamber, a piston part 21, and a spring 22. The replenishment port 18 is formed in the fireproof Part case 19. The replenishment cylinder 20 extends outward (outside the fireproof chamber 5) from the edge of the replenishment port 18. A replenishment chamber communicating with the fireproof chamber 5 is formed inside the replenishment cylinder 20. The piston part 21 and the spring 22 are located in the replenishment chamber. The gap between the outer edge of the piston part 21 and the inner wall of the replenishment cylinder 20 is not larger than the particle diameter of the fireproof particles. One end of the spring 22 is connected to the piston part 21, and the other end is connected to the inner wall of the outer end of the replenishment cylinder 20.

[0014] In the frame arrester of the present invention, when a fire or explosion occurs on one side of the frame arrester, the flame first passes through the first case 1 or the second case 2, and then flows through the fireproof Part 4. At this time, the flame flows from one fireproof Part opening to the other fireproof PartOver the opening, it exchanges heat with the fire prevention particles in the fire prevention chamber 5 to lower the temperature. Also, radicals from the combustion reaction are quenched on the surface of the particulate matter, thereby reducing the concentration of radicals from the combustion reaction. When the temperature and the concentration of radicals do not sufficiently decrease for the combustion reaction, the combustion stops. In this way, it is possible to effectively prevent the propagation of flames and explosions to the other side and exacerbation of the accident.

[0015] The flame arrester capable of automatically eliminating defects in the fire prevention part according to the present invention can automatically eliminate defects in the fire prevention part, has a simple structure, and is fireproof Part 4 uses a particulate fireproof material. The particulate fireproof material has a large relative surface area, a large heat exchange area, is easy to conduct heat, has excellent fireproof performance, and moreover, has the advantages of being difficult to clog and easy to clean, which are given to the fireproof Part 4 itself. Furthermore, the fireproof Part 4 further includes a fire prevention particle replenishment structure. When filling the fire prevention particles, after the fire prevention chamber 5 is filled with the fire prevention particles, the fire prevention particles enter the replenishment chamber, hit the piston part 21, and move to the outside of the fire prevention chamber 5, compressing the spring 22. When the flame arrester is used normally, the spring 22 always remains in a compressed state, and the fire prevention particles in the replenishment chamber are held in the replenishment chamber. When the flame arrester is subjected to an impact due to an explosion, the fire prevention particles in the fire prevention chamber 5 become denser, and the blocking part may also be deformed by the impact. In this case, a certain gap is generated in the fire prevention chamber 5 (the part at the top). At this time, due to the biasing force of the spring 22 in the compressed state, the piston part 21 moves along the extending direction of the replenishment chamber, pushing the fire prevention particles in the replenishment chamber into the fire prevention chamber 5 to refill the gap generated in the fire prevention chamber 5 and fill the fire prevention chamber 5 with the fire prevention particles, thereby Part 4 is prevented from developing defects (gaps) and losing its fire prevention ability. Therefore, when the flame arrester capable of automatically eliminating defects in the fire prevention part according to the present invention is deformed due to an impact caused by an explosion, it can automatically eliminate the defects in the fire prevention part and continue to normally exhibit the effects of preventing fire spread and explosion protection.

[0016] Here, the replenishment chamber extends along a straight line and has a constant cross-section in the extending direction. For example, the replenishment chamber may be in the shape of a straight cylinder, and may have a cross-section of any appropriate shape such as circular, elliptical, or square so that the piston portion 21 can move smoothly within the replenishment chamber.

[0017] Furthermore, as shown in FIGS. 2 and 3, the piston portion 21 may be formed in a plate shape, and the extending direction thereof is perpendicular to the extending direction of the replenishment chamber.

[0018] As long as the gap between the outer edge of the piston portion 21 and the inner wall of the replenishment cylinder 20 is equal to or less than the particle diameter of the fire prevention particles, the fire prevention particles can enter the portion outside the piston portion 21 of the replenishment chamber and can be pushed and moved without causing a failure of the fire prevention particle replenishment mechanism. Generally, the piston portion 21 may be configured such that the outer edge is substantially close to the inner wall of the replenishment cylinder 20.

[0019] Furthermore, in order to more reliably maintain the function of the fire prevention particle replenishment structure, preferably, when the piston portion 21 moves along the extending direction of the replenishment chamber within the replenishment chamber, the spring 22 is always in a compressed state.

[0020] Also, for fire prevention Part To facilitate the replenishment of fire prevention particles into the [fire prevention area] and to facilitate the maintenance of the particle fire prevention replenishment structure, preferably, the outer end of the replenishment cylinder 20 has an outer end opening and a removable outer end plate 23 for closing the outer end opening.

[0021] Furthermore, the outer end plate connection flange may extend outward from the outer edge of the outer end opening, and the outer end plate 23 and the outer end plate connection flange are connected by a connecting member. For example, a plurality of through holes may be formed at equal intervals in the circumferential direction of the outer end plate connection flange, and a plurality of through holes are correspondingly formed in the outer end plate 23. The outer end plate connection flange and the outer end plate 23 are connected by bolts passing through the corresponding through holes of the outer end plate connection flange and the outer end plate 23 and nuts fitting with the bolts.

[0022] FIG. 6 shows a flame arrester capable of automatically eliminating defects in a fire prevention part according to a preferred embodiment. The flame arrester capable of automatically eliminating defects in the fire prevention part has substantially the same structure as the embodiments of FIGS. 1 to 3 except for the following differences. One of the fire prevention Part From the opening to the other fire prevention Part Along the direction toward the opening, the fire prevention chamber 5 includes at least two compartments 16. The particle diameter of the fire prevention particles filled in the first compartment 16 is larger than the particle diameter of the fire prevention particles filled in the second compartment 16. In the flame arrester capable of automatically eliminating defects in the fire prevention part, at least one fire prevention particle replenishment structure is included for each compartment 16.

[0023] Each fire prevention particle replenishment structure replenishes fire prevention particles to the corresponding compartment. In this embodiment, the fire prevention chamber 5 has a plurality of compartments 16, whereby, from one of the fire prevention Part Opening to the other fire prevention Part In the direction toward the opening, the flame passes through these multiple compartments 16 sequentially. Specifically, after passing through the first compartment, it passes through the second compartment. In the first compartment, since the flame-retardant particles have a large particle diameter, the pressure wave is separated from the flame and the deflagration is converted into a combustion explosion. Thus, the compartment (bed) filled with flame-retardant particles having a large particle diameter is resistant to explosion shock, and has high resistance to deformation of such a bed. Also, in the subsequent second compartment, the flame-retardant particles have a small particle diameter and a high thermal conductivity, which can more quickly reduce the temperature of the flame and extinguish the flame. With such a combined configuration, the fire prevention Part 4 can obtain a better fire prevention and explosion protection effect.

[0024] As an embodiment, as shown in FIG. 7, the fire prevention chamber 5 may include two compartments. The particle diameter of the fire prevention particles in the first compartment on the inlet side is larger than the particle diameter of the fire prevention particles in the second compartment on the outlet side. In this embodiment, the particle diameter of the fire prevention particles filled in the first compartment 16 is 3 mm to 5 mm, and the particle diameter of the fire prevention particles filled in the second compartment 16 is 1 mm to 2.5 mm.

[0025] Preferably, as shown in FIG. 8, along the direction from one of the fireproof Part openings to the other fireproof Part opening, the fireproof chamber 5 may include at least three compartments. Along the direction from the fireproof Part opening to the center, the particle size of the fireproof particles filled in the outer compartment is larger than the particle size of the fireproof particles filled in the inner compartment. Thereby, regardless of whether the flame enters from the first case 1 or the second case 2, good fireproof and explosion-proof effects can be obtained in the fireproof Part 4. In this case, the flame arrester is used as a particle type flame arrester that can automatically eliminate defects in both directions, and there is no limitation on the installation direction.

[0026] Alternatively, the fireproof chamber 5 may include three compartments 16, the particle sizes of the fireproof particles filled in the compartments on both sides are equal, and both are larger than the particle size of the fireproof particles filled in the compartment in the center. In this case, the fireproof chamber 5 has a completely symmetrical structure. For example, the particle size of the fireproof particles filled in the compartments 16 on both sides may be 3 to 5 mm, and the particle size of the fireproof particles filled in the compartment 16 in the center may be 1 mm to 2.5 mm.

[0027] Furthermore, the fireproof Part 4 may be in the shape of a straight cylinder with both ends open, the interface between the compartments is perpendicular to the extending direction of the fireproof Part 4, and a partition mesh 17 extending along the interface is provided on each interface to separate the groups or particles in each compartment, thereby forming a plurality of fireproof beds. The partition mesh 17 may be a metal mesh that can withstand high temperatures. The extending direction of the replenishment chamber is perpendicular to the extending direction of the fireproof Part 4.

[0028] Regarding the selection of the fireproof particles, the fireproof particles may be one or a combination of a plurality of types among metals, organometallic framework materials, molecular sieve materials, natural zeolites, and ceramics.

[0029] The fireproof particles in each compartment 16 may be of the same or different materials. For example, in one embodiment, the fireproof chamber 5 includes three compartments, and the fireproof particles filled in the compartments on both sides are alumina ceramic particles with a particle diameter of 5 mm, and the fireproof particles filled in the central compartment are stainless steel balls with a particle diameter of 2 mm. In another embodiment, the fireproof chamber includes three compartments, and the fireproof particles filled in the compartments on both sides are natural zeolites with a particle diameter of 4 mm, and the fireproof particles filled in the central compartment are molecular sieve materials with a particle diameter of 2.2 mm.

[0030] Furthermore, in the frame arrester capable of automatically eliminating defects in the fireproof part, the first case 1 and the second case 2 each have an inner opening formed on the side facing each other, and an inner connection flange 3 extending outward from the edge of the inner opening is formed. The frame arrester capable of automatically eliminating defects in the fireproof part further includes a connection part, and the fireproof Part 4 includes two blocking parts respectively provided at the two fireproof Part openings, a fireproof chamber 5 is defined between the two blocking parts, a plurality of openings are formed in the blocking parts, both ends of the connection part are respectively connected to the inner connection flange 3 of the first case 1 and the inner connection flange 3 of the second case 2, and the fireproof Part 4 is interposed between the first case 1 and the second case 2.

[0031] The fireproof Part 4 is interposed between the first case 1 and the second case 2 on both sides, but is not directly connected to the first case 1 and the second case 2. Instead, by integrally connecting the inner connection flange 3 of the first case 1 and the inner connection flange of the second case 2 through the connection part, it is limited between the first case 1 and the second case 2. Therefore, the fireproof PartWhen cleaning, maintenance, or replacement of 4 is required, disconnecting the connection part ensures fire protection Part 4 can be removed. Since the connection part is located on the inner connection flange that extends outward from the edge of the inner openings of the first case 1 and the second case 2, it is easy to attach and detach, thereby improving the convenience of attaching and detaching the frame arrester, and Part multiple Part The multi - type structure that allows individual processing also reduces the processing difficulty and cost of the frame arrester.

[0032] Alternatively, on the inner connection flange 3 of the first case 1 and the inner connection flange 3 of the second case 2, first connection through - holes are formed corresponding to each other. The connection part includes a first link 6 and a first nut 7. One end of the first link 6 has a first screw Part formed, and the other end has another first screw Part or a first cap formed. The first nut 7 can be screwed onto the first screw Part The first link 6 passes through the first connection through - holes of the first case 1 and the second case 2, and the maximum outer diameter of either the first nut 7 or the first cap is larger than the maximum inner diameter of the corresponding first connection through - hole on that side.

[0033] In the above form, the connection part is constituted by the first nut 7, the first link 6, etc., making it easy to attach and detach the fire - protection Part 4. In the above form, two embodiments are included. As one of them, both ends of the first link 6 are provided with first screws Part and the first nut 7 can be screwed onto any of these first screws Part . When the first link 6 passes through the first connection through - holes of the first case 1 and the second case 2, by tightening the first nuts 7 on the first screws Part at both ends, the first case 1 and the second case 2 are connected to each other due to the restriction by the two first nuts 7. When removing, loosen the first nut 7 on either side and remove the first link 6. As the other one, one end of the first link 6 has a first screw Part, a cap is provided at the other end. When the first link 6 penetrates the first connection through-holes of the first case 1 and the second case 2, the first nut Part in Part is tightened, and due to the restriction by the first nut 7 and the cap, the first case 1 and the second case 2 are connected to each other. When removing, loosen the first nut 7 and the first link 6 can be removed. In this embodiment, since there is a fixed cap, the convenience and stability of the operation of connecting the first case 1 and the second case 2 to each other are improved.

[0034] Furthermore, the connection part shown in FIG. 1 is for fireproof Part 4 to be stably clamped between the first case 1 and the second case 2, and at least two are provided in the circumferential direction of the fireproof Part 4.

[0035] Also, specifically, the fireproof Part 4 may be in a straight cylindrical shape, and the first link 6 extends along the extending direction of the fireproof Part 4. For example, the fireproof Part 4 may be in a cylindrical shape, and the first link 6 extends along the axial direction of the fireproof Part 4. In this way, it is advantageous for further improving the connection stability between the first case 1 and the second case 2.

[0036] Preferably, in order to further improve the connection stability between the first case 1 and the second case 2, a plurality of the connection parts are provided in the circumferential direction of the inner connection flange 3 of the first case 1 and the second case 2. For example, a plurality of sets of connection parts including the first link 6 and the first nut 7 are provided in the circumferential direction of the inner connection flange 3 of the first case 1 and the second case 2, and the plurality of connection parts may be provided at equal intervals in the circumferential direction of the inner connection flange 3 of the first case 1 and the second case 2.

[0037] Furthermore, as shown in FIG. 1, in this embodiment, the first case 1 and the second case 2 each have an expansion Part 8 on one side of the inner opening, and the expansion Part8 is configured such that the cross-sectional area increases toward the inner opening, so that when a fire or explosion occurs on one side of the frame arrester, the flame first expands in the first case 1 or the second case 2 Part through 8 and then expands Part Since the cross-sectional area of 8 increases toward the fireproof Part 4, the flow area of the flame gradually increases, and the forward speed and pressure of the flame gradually decrease, which is advantageous for enhancing the fireproof and explosion-proof effects.

[0038] Furthermore, specifically, as shown in FIG. 1, in this embodiment, the expansion Part 8 is configured as a truncated conical cylinder with both ends open, and the first case 1 and the second case 2 are respectively a cylinder Part connected to the expansion Part 8, further including 9, and the cylinder Part 9 extends from the edge of the side of the expansion Part 8 opposite to the inner opening along the direction of the rotation axis of the truncated conical cylinder in the direction opposite to the inner opening. In this case, the fireproof Part 4 is cylindrical.

[0039] Here, the ratio of the inner diameter on the inner opening side of the expansion Part 8 to the inner diameter on the side opposite to the inner opening is preferably controlled to be 1.5 to 4, so that, without causing an increase in the processing difficulty of the expansion Part 8, an increase in cost, or deterioration of the frame arrester structure stability, the effect of reducing the forward speed and pressure of the flame can be further obtained. More preferably, the ratio of the inner diameter on the inner opening side of the expansion Part 8 to the inner diameter on the side opposite to the inner opening is preferably controlled to be 2.2 to 2.8.

[0040] Furthermore, preferably, the first case 1 and the second case 2 have a symmetrical structure with respect to each other. For example, as shown in FIG. 1, the first case 1 and the second case 2 are completely symmetrical in both shape and size, and the outer diameter of the cylindrical fireproof Part 4 is the expansion PartIt is approximately equal to the outer diameter at the inner opening of 8, and is coaxial with the first case 1, the second case 2, and the fireproof Part 4 is provided. Further, the inner connection flange 3 is perpendicular to the rotation axis of the frustum-shaped cylinder, which is advantageous for improving the connection stability between the first case 1 and the second case 2.

[0041] fireproof Part A gasket may be provided between 4 and the inner connection flange 3. In order to attach the flame arrester capable of automatically eliminating defects of the fireproof part to the corresponding pipes and devices, the first case 1 and the second case 2 are respectively formed with mounting flanges 15 on opposite sides of each other.

[0042] As shown in FIG. 2, preferably, the fireproof Part On the side walls at both ends of 4, the fireproof Part A groove 10 is formed in the circumferential direction of the opening, and the blocking part is mounted in the groove 10.

[0043] The blocking part may be press-fitted into the groove 10 so that the blocking part is connected to the main body of the fireproof Part without passing through other connecting members.

[0044] Alternatively, on each of the blocking parts at both ends of the fireproof Part 4, second connection through holes are formed corresponding to each other, and the fireproof Part 4 further includes a second link 11 and a second nut 12. One end of the second link 11 is formed with a second screw Part and the other end is formed with another second screw Part or a second cap. The second nut 12 is threadable with the second screw Part The second link 11 passes through the second connection through holes of the blocking parts at both ends of the fireproof Part 4, and the maximum outer diameter of either the second nut 12 or the second cap is larger than the maximum inner diameter of the corresponding second connection through hole on the corresponding side.

[0045] In the above-described form, the attachment and detachment of the blocking portion is made easier by the second link 11, the second nut 12, etc. In the above-described form, two embodiments are included. As one of them, second screws are provided at both ends of the second link 16. Part The second nut 12 can be screwed onto any of these second screws. Part When the second link 11 passes through the second connection through holes of the two blocking portions, by tightening the second nuts 12 on the second screws at both ends thereof, due to the restriction by the two second nuts 12, the blocking portions at both ends and the central fireproof Part main body are connected to each other. When removing, loosen the second nut 12 on either side and remove the second link 11. As the other one, a second screw is provided at one end of the second link 11 and a cap is provided at the other end. When the second link 11 passes through the second connection through holes of the two blocking portions, by tightening the second nuts 12 on the second screws Part therein, due to the restriction by the second nut 12 and the cap, the blocking portions at both ends and the central fireproof Part main body are connected to each other. When removing, loosen the second nut 12 and the second link 11 can be removed. In this embodiment, since there is a fixed cap, the convenience and stability of the operation of connecting the two blocking portions and the central fireproof Part main body to each other are further improved. Part main body are connected to each other. When removing, loosen the second nut 12 and the second link 11 can be removed. In this embodiment, since there is a fixed cap, the convenience and stability of the operation of connecting the two blocking portions and the central fireproof Part main body to each other are further improved.

[0046] Preferably, at both ends of the fireproof Part 4, the edge portion of the blocking portion abuts against the inner connection flange 3 on the corresponding side. Considering the component requirement that grooves 10 are formed in the circumferential direction of the opening of the fireproof Part 4 and the blocking portion is attached in the grooves 10, when the fireproof Part 4 is interposed between the first case 1 and the second case 2, a restricting action is also applied to the blocking portion by the inner connection flange 3 on the corresponding side, so it is understood that the structural stability of the blocking portion is better, the resistance to explosion is high, and deformation becomes difficult. Part 4 is interposed between the first case 1 and the second case 2, a restricting action is also applied to the blocking portion by the inner connection flange 3 on the corresponding side, so it is understood that the structural stability of the blocking portion is better, the resistance to explosion is high, and deformation becomes difficult.

[0047] To enhance the explosion-resistant deformability of the blocking part, preferably, the blocking part includes a rigid baffle plate 13. Further, the blocking part further includes a mesh 14 located inside the baffle plate 13. The mesh 14 is a net-shaped metal mesh that can withstand high temperatures and is used to confine the fireproof particles within the fireproof chamber 5. On the other hand, the baffle plate 13 can function as a rigid support structure, thereby improving the structural stability of the blocking part, enhancing its resistance to explosion, and making deformation difficult.

[0048] Here, the mesh size of the mesh 14 is determined by the particle size of the fireproof particles in the fireproof chamber 5.

[0049] It is understood that when the mesh 14 is provided, the size of the opening of the baffle plate 13 can be arbitrary. For example, FIGS. 5A to 5C show three available baffle plates 13, and any of these three baffle plates 13 can be combined with the mesh 14 in FIG. 4. These meshes 14 and baffle plates 13 are all provided with respect to the cylindrical fireproof Part body, and the cylindrical fireproof Part body has a circular end. Therefore, the baffle plate 13 and the mesh 14 also have corresponding circular outer contours. When the contour of the fireproof Part body changes, the shapes of the outer contours of the baffle plate 13 and the mesh 14 also change accordingly. The baffle plate 13 includes a circumferential frame and at least one inner frame (cylindrical fireproof PartCorresponding to 4, the figure has an annular frame), and the baffle plate 13 further includes a radial link connecting the inner frame and the circumferential frame, and a plurality of the radial links are provided at intervals in the circumferential direction of the baffle plate 13. In the illustrated case, the radial links extend radially from the center to the edge of the baffle plate 13. Regarding the joining of the mesh 14 and the baffle plate 13, in this embodiment, connection through holes are provided at the centers of both the baffle plate 13 and the mesh 14, and the second link 11 passes through these connection through holes to integrally connect the baffle plate 13 and the mesh 14. However, in addition to this, or instead of this, the mesh 14 may be connected to the baffle plate 13 by other connection methods. It is understood that the baffle plate 13 may be in any other appropriate form. For example, as shown in FIG. 5D, the baffle plate 13 is configured as a lattice, and when the gap between the lattices of the lattice-shaped baffle plate 13 is less than the particle diameter of the fireproof particles, the mesh 14 may be omitted and only the baffle plate 13 may be provided individually.

[0050] In the flame arrester capable of automatically eliminating defects in the fireproof part of the present invention, when a fire or explosion occurs on one side of the flame arrester, the flame first passes through the first case 1 or the second case 2, and particularly expands Part When 8 exists, it expands Part When the cross-sectional area of 8 is fireproof Part 4 increases as it goes towards 4, so the flow area of the flame gradually increases, and the advancing speed and pressure of the flame gradually decrease. Next, the flame flows through the fireproof Part 4, and at this time, it exchanges heat with the fireproof particles in the fire extinguishing chamber 5 to lower the temperature, and also the radicals generated by the combustion reaction are quenched on the surface of the particulate matter, whereby the concentration of the radicals generated by the combustion reaction decreases. When the temperature and the concentration of the radicals decrease sufficiently for the combustion reaction, the combustion stops. In this way, it is possible to effectively prevent the flame and explosion from propagating to the other side and aggravating the accident.

[0051] When selecting the fireproof particles, in addition to the above materials, the shape of the fireproof particles includes, but is not limited to, shapes such as spherical and ellipsoidal, in which fine flow passages can be formed between the fireproof particles. In this way, gas can flow through these flow passages. Usually, the flow passages that can be formed between the fireproof particles are required to meet the explosion-proof grade. For example, when the explosion-proof grade is Class IIA, the flow passage is 0.85 or less. For example, when the explosion-proof grade is Class IIB3, the flow passage is 0.6 or less. For example, when the explosion-proof grade is Class IIB3, the flow passage is 0.4 or less. Further specifically, for example, the fireproof particles may be spherical metal particles with a particle diameter of 2 mm. In this case, a flow passage of 0.73 mm is formed between the spherical metal particles filling the fire extinguishing chamber 5, and it can meet the operating conditions of explosion-proof grade IIA. Under normal operating conditions, gas flows in from the outer opening of one side of the case, expands Part through 8 and then enters the fireproof Part 4, then flows through the flow passage formed between the fireproof particles, and further passes through the contraction of the other side of the case Part 8 and flows out from the outer opening of the other side of the case.

[0052] As shown in FIG. 9, the present invention provides a frame arrester that can exchange fireproof particles online and automatically eliminate defects in the fireproof part. The frame arrester includes a first case 1, a second case 2, and a fireproof Part 4 located between the first case 1 and the second case 2. The fireproof Part 4 has a fireproof Part case 19. The fireproof Part case 19 is hollow and has two fireproof Part openings facing the first case 1 and the second case 2 respectively. The fireproof Part 4 further includes two blocking parts provided at the two fireproof Part openings respectively. A fireproof chamber 5 is defined between the two blocking parts. A plurality of openings are formed in the blocking parts, and the fireproof chamber 5 is filled with fireproof particles. The fireproof Part4 further includes a fireproof particle exchange structure, the fireproof particle exchange structure includes a fireproof particle discharge port 24 and a fireproof particle replenishment port 25, and the fireproof particle discharge port 24 is formed at the bottom of the fireproof Part case 19, and the fireproof particle replenishment port 25 is formed at the top of the fireproof Part case 19, and the fireproof Part 4 further includes a discharge valve 27 for controlling the opening and closing of the fireproof particle discharge port 24 and a replenishment valve 29 for controlling the opening and closing of the fireproof particle replenishment port 25.

[0053] In the present invention, when the exchange of fireproof particles in the fireproof chamber 5 is required by the fireproof particle exchange structure provided in the fireproof Part 4, the discharge valve 27 is opened to discharge the fireproof particles in the fireproof chamber 5 from the fireproof particle discharge port 24. When the discharge of the fireproof particles in the fireproof chamber 5 is completed, the discharge valve 27 is closed. Then, the replenishment valve 29 is controlled to open the fireproof particle replenishment port 25, and new fireproof particles are replenished from the fireproof particle replenishment port 25 into the fireproof chamber 5. After the replenishment is completed, the replenishment valve 29 may be controlled to close the fireproof particle replenishment port 25, whereby a frame arrester capable of online exchange of fireproof particles can be used. When exchanging fireproof particles, it is not necessary to remove the frame arrester from the pipeline, tank or device to be arranged, and the online exchange of fireproof particles can be easily implemented.

[0054] Specifically, in some embodiments, the fireproof particle exchange structure includes a discharge passage 26 extending from the fireproof particle discharge port 24, the discharge valve 27 is attached to the discharge passage 26, the fireproof particle exchange structure further includes a replenishment passage 28 extending from the fireproof particle replenishment port 25, and the replenishment valve 29 is attached to the replenishment passage 28.

[0055] To facilitate the transportation of fireproof particles in the passage, both the discharge passage 26 and the replenishment passage 28 are straight cylindrical ones extending in the vertical direction. Further, in the figure, both the discharge passage 26 and the replenishment passage 28 are tubular.

[0056] Preferably, the fireproof particle exchange structure is a fireproof provided at the outer end of the discharge passage 26 and / or the outer end of the replenishment passage 28. Part Further includes a connector 30. As shown in FIGS. 10 and 11, a frame arrester capable of online exchange of fireproof particles further includes a barrel 31 provided with a barrel connector 32 that can be fitted and connected to the fireproof Part connector 30. The barrel 31 is used to contain the fireproof particles to be filled in the fireproof chamber 5 or receive the fireproof particles discharged from the fireproof chamber 5. On the other hand, the fireproof Part connector 30 and the barrel connector 32 are fitted and connected, so that the barrel 31 and the fireproof Part 4 can be quickly connected. For example, either the fireproof Part connector 30 or the barrel connector 32 can use a tie-rod type quick connector, thereby realizing a high-speed connection that does not require tools.

[0057] Furthermore, in some embodiments, a first barrel opening 35 and a barrel passage 33 extending from the first barrel opening 35 are formed in the barrel 31, and a barrel valve 34 for opening and closing control of the barrel opening 35 is provided in the barrel passage 33. The barrel connector 32 is provided at the outer end of the barrel passage 33. Furthermore, in order to facilitate the entry and exit of fireproof particles into and out of the barrel 31, the barrel passage 33 may be in a straight cylindrical shape, for example, the straight tubular shape shown in the figure.

[0058] Furthermore, in some embodiments, a second barrel opening and a removable cover for closing the second barrel opening are further formed in the barrel 31. For example, the second barrel opening may face the first barrel opening 35, but the second barrel opening may be made larger. For example, the barrel 31 can be completely opened on the side facing the first barrel opening 35 to facilitate replenishing the barrel 31 with new fireproof particles or discharging the disposable fireproof particles contained in the barrel 31.

[0059] In some embodiments, two barrels 31 for fitting and connecting to the discharge passage and the replenishment passage respectively may be provided.

[0060] As shown in FIG. 9, in some embodiments, the flameless arrester capable of online exchange of the fireproof particles is the fireproof Part gas entering 4 and the fireproof Part further includes a pressure difference detection unit for detecting the pressure difference between the gas discharged from 4. Thereby, the operating condition of the fireproof Part 4 may be monitored by the pressure difference detection unit. When the fireproof Part 4 cannot operate normally due to blockage, the value of the pressure difference detected by the pressure difference detection unit increases, and the operator can determine the presence or absence of blockage of the fireproof Part 4 and the necessity of exchanging the fireproof particles in the fireproof chamber 5 from the detected value of the pressure difference.

[0061] For example, alternatively, the pressure difference detection unit includes a first pressure detector 36 and a second pressure detector 37. The first pressure detector 36 is attached to the first case 1, and the detection probe extends into the cavity in the first case 1. The second pressure detector 37 is attached to the second case 2, and the detection probe extends into the cavity in the second case 2.

[0062] Preferably, the first pressure detector 36 and the second pressure detector 37 are attached as close as possible to the fireproof Part 4. The flameless arrester capable of online exchange of the fireproof particles may further include a control unit and an alarm unit. The signal output terminal of the pressure difference detection unit is electrically connected to the signal input terminal of the control unit, and the signal output terminal of the control unit may be electrically connected to the signal input terminal of the alarm unit. When the control unit receives the value of the pressure difference detected by the first pressure detector 36 and the second pressure detector 37, it determines whether the exchange of the fireproof particles is necessary. For example, when the value of the pressure difference reaches a predetermined value, it sends a signal to the alarm unit, and the alarm unit gives an alarm to prompt the operator to exchange the fireproof particles.

[0063] In the preferred embodiment shown in FIG. 12, in the frame arrester capable of online replacement of the fireproof particles, the first case 1 and the second case 2 are each formed with an inner opening on the side facing each other, and are extended toward the inner opening side Part 8, and the extension Part 8 is configured such that the cross-sectional area increases as it approaches the inner opening. In another preferred embodiment shown in FIG. 13, the fireproof Part both ends of the case 19 may have an extension Part 8, and the extension Part 8 has a cross-sectional area that increases as it moves away from the blocking portion.

[0064] Therefore, when a fire or explosion occurs on one side of the frame arrester capable of online replacement of the fireproof particles, the flame first enters the fireproof Part 4 through the first case 1 or the second case 2, and then enters the extension Part 8 first. Since the cross-sectional area of the extension Part 8 increases as it moves away from the blocking portion, the flow area of the flame gradually increases, and the forward speed and pressure of the flame gradually decrease, which is advantageous for improving the fireproof and explosion-proof effects.

[0065] More specifically, in the present embodiment, the extension Part 8 is a truncated conical cylindrical body with both ends open, and the fireproof Part case 19 further has a cylinder Part located between two of the extensions Part 8. Further, in the extension Part 8, the ratio of the inner diameter of the side with the larger cross-sectional area to the inner diameter of the side with the smaller cross-sectional area is preferably controlled to be 1.2 to 2, thereby improving the effect of reducing the forward speed and pressure of the flame without causing an increase in the processing difficulty of the extension Part 8, an increase in cost, and a deterioration in the stability of the frame arrester structure capable of online replacement of the fireproof particles. More preferably, in the extension Part 8, the ratio of the inner diameter of the side with the larger cross-sectional area to the inner diameter of the side with the smaller cross-sectional area is preferably controlled to be 1.4 to 1.7.
