Description

Technical Field

[0001] The present application relates to the technical field of explosion-proof and blast-reducing walls, and more specifically, to a prefabricated explosion-proof and blast-reducing wall. Background Art

[0002] A phase change heat exchange energy-saving wall, usually simply referred to as a phase change material wall, is an innovative wall structure integrating advanced phase change materials. Through its unique heat regulation mechanism, the phase change heat exchange energy-saving wall can significantly reduce the dependence of buildings on traditional heating and cooling systems. For buildings using phase change material walls, their heating and cooling energy consumption can be reduced by 20% - 30%. This not only helps to reduce the building operation cost, but also makes a positive contribution to alleviating the energy tension and reducing greenhouse gas emissions.

[0003] As a large energy consumer, chemical plants can reduce energy consumption, which not only helps to reduce operation costs, but also contributes to environmental protection. The phase change heat exchange energy-saving wall reduces the dependence on traditional heating and cooling systems by absorbing and storing heat and releasing heat when needed. This intelligent heat regulation mechanism can significantly reduce energy consumption and improve energy utilization efficiency.

[0004] The prior art with the publication number of CN202023013111.6 discloses a phase change heat exchange energy-saving wall material structure, including a wall body, a fixing mechanism, and a phase change heat exchange mechanism. The wall body is connected to the fixing mechanism, and the fixing mechanism is connected to the phase change heat exchange mechanism. A number of groups of fixing mechanisms are fixedly arranged inside the wall body. The fixing mechanism includes a fixing cylinder, a fixing plate, and a fixing rod. Fixing rods are fixedly arranged at the upper and lower ends of several fixing cylinders. A number of fixing plates are arranged at the upper and lower ends of the fixing cylinder. One end of the fixing rod away from the fixing cylinder is fixedly connected to the fixing plate. In this application, a storage cylinder filled with phase change heat material is inserted into the fixing cylinder, and the mounting plate on one side of the storage cylinder is arranged inside the mounting groove. At this time, the mounting plate and the fixing cylinder are fixed by tightening bolts. Since a contact plate is arranged on one side of the storage cylinder, the heat conductivity between the phase change heat material and the outside is better, improving the use effect.

[0005] However, the above prior art still has the disadvantage of poor impact resistance. When an explosion risk suddenly occurs in a chemical plant, it usually can only block the explosion shock wave by its own material and structure, and cannot effectively weaken the explosion impact. This not only easily causes damage to the wall, but also easily causes the spread of fire during the explosion, posing a large safety hazard.

[0006] In view of this, we propose a prefabricated explosion-proof and blast-reducing wall. Summary of the Invention

[0007] 1. Technical Problems to be Solved

[0008] The purpose of this application is to provide a prefabricated explosion-resistant and explosion-reducing wall, which solves the technical problems raised in the above-mentioned background technology.

[0009] 2. Technical solution

[0010] The technical solution of this application provides a prefabricated explosion-resistant and explosion-reducing wall, including a phase change heat exchange energy-saving wall. A blast vent is provided on the phase change heat exchange energy-saving wall. The blast vent is square. A blast window is installed on the blast vent. A pressure-bearing mechanism is provided on the outer surface of the phase change heat exchange energy-saving wall. The pressure-bearing mechanism is used to reduce the explosion pressure. The pressure-bearing mechanism includes a pressure-bearing box. A pressure relief hole is opened on the surface of the pressure-bearing box away from the phase change heat exchange energy-saving wall. A plurality of bearing plates that are rotatably connected to each other are arranged inside the pressure-bearing box. A first spring is connected to the plurality of bearing plates together. An airbag is also arranged inside the pressure-bearing box. A storage box is also provided on the outer surface of the phase change heat exchange energy-saving wall. Fire extinguishing materials are arranged inside the storage box. A transmission box is provided above the storage box. An opening mechanism is arranged inside the transmission box. The airbag is connected to the opening mechanism. When an explosion occurs, the airbag is squeezed, so that the internal gas drives the opening mechanism to act and then opens the storage box, so that the fire extinguishing materials in the storage box are ejected. The opening mechanism includes an air outlet pipe. One end of the air outlet pipe is communicated with the airbag. The other end of the air outlet pipe is connected to a connection box. A sliding plate is slidably connected inside the connection box. The opening mechanism includes a sealing plate and a cover plate. An air outlet is opened on the side wall of the transmission box. A spray pipe is connected inside the air outlet. A feed inlet is opened at the bottom of the transmission box. The sealing plate and the cover plate correspond to the air outlet and the feed inlet respectively. The gas in the airbag pushes the sliding plate to move, and the sliding plate then drives the sealing plate and the cover plate to move.

[0011] By adopting the above technical solution, when an explosion occurs, during the process of the high-pressure gas moving towards the phase change heat exchange energy-saving wall, since the pressure that the pressure relief opening can bear is less than that of other parts, the blast window breaks. At this time, the explosion air pressure blows towards the bearing plates. Through the action of the plurality of bearing plates and the first spring, part of the pressure is absorbed. Then the high-pressure gas continues to blow towards the airbag, and the airbag deforms. The airbag absorbs part of the explosion pressure. At the same time, the gas in the airbag blows towards the opening mechanism, and the sealing plate and the cover plate in the opening mechanism open backward. Under the action of high pressure, the fire extinguishing materials in the storage box are ejected through the spray pipe for fire extinguishing.

[0012] As an alternative solution to the technical solution of this application document, the explosion vent window is made of glass. The pressure-bearing mechanism further includes fixed rails. Two groups of fixed rails are provided and fixed on the upper and lower bottoms of the pressure-bearing box respectively. A plurality of bearing plates are slidably connected to the fixed rails. A connecting unit is rotatably connected between the plurality of bearing plates. The connecting unit is composed of a plurality of connecting rods rotatably connected to each other. Two sets of mounting frames are fixed in the pressure-bearing box. The first spring is connected in the mounting frame. A bearing plate close to the explosion vent window is connected to the first spring.

[0013] By adopting the above technical solution, a plurality of bearing plates are rotatably connected through the connecting unit, and the plurality of bearing plates can be combined into a whole, thereby improving the overall connection strength, and further being able to absorb more explosion impacts. Moreover, a first spring is commonly connected between the plurality of bearing plates, and the explosion pressure can be converted into the elastic potential energy of the spring.

[0014] As an alternative solution to the technical solution of this application document, a slide rail is provided inside the side wall of the transmission box. The sealing plate is slidably connected in the slide rail. A second spring is connected to the sealing plate. The other end of the second spring is connected to the transmission box. A push rod is fixedly connected to the slide plate. The push rod extends into the transmission box and is located above the sealing plate.

[0015] By adopting the above technical solution, under the high pressure of the explosion, the gas in the airbag is discharged and squeezes the slide plate and the push rod. The push rod then acts on the sealing plate, causing the sealing plate to move against the elastic force of the second spring, thereby connecting the air outlet and the transmission box, and further enabling the fire extinguishing material to be ejected from the nozzle.

[0016] As an alternative solution to the technical solution of this application document, the cover plate is slidably connected to the bottom of the transmission box, and a third spring is connected to the cover plate. The other end of the third spring is connected to the transmission box. A first triangular frame is connected to the sealing plate. A second triangular frame is fixedly connected to the cover plate. The first triangular frame and the second triangular frame correspond to each other. A pull rod is connected to the second triangular frame. The pull rod extends outside the transmission box.

[0017] By adopting the above technical solution, as the sealing plate moves, the first triangular frame on the sealing plate moves synchronously. The first triangular frame acts on the second triangular frame, thereby driving the second triangular frame to move. The second triangular frame drives the cover plate connected thereto to move synchronously. As the cover plate moves, the feed port covered by the cover plate is exposed, and the fire extinguishing material in the storage tank is ejected under the action of high pressure. At the same time, the second triangular frame is stuck with the first triangular frame under the elastic force of the third spring, that is, the first triangular frame is blocked by the bottom of the second triangular frame and cannot rise. When fire extinguishing is not required, by pushing the pull rod, the second triangular frame is moved away from the first triangular frame. At this time, the first triangular frame and the sealing plate return to their original positions under the elastic force of the second triangular frame, that is, they cover the air outlet again. Without the blockage of the first triangular frame, the cover plate also covers the feed port again under the action of the third spring.

[0018] As an alternative solution of the technical solution of this application document, the storage tank and the transmission box are communicated through the feed port, and two transmission boxes are provided and distributed on both sides of the pressure-bearing box. A one-way valve is provided on the air outlet pipe, and the one-way valve only allows the gas in the airbag to be discharged.

[0019] By adopting the above technical solution, the one-way valve is provided to only allow the gas in the airbag to be discharged. The purpose of this setting is to prevent the fire extinguishing material from entering the airbag through the air outlet pipe. When extinguishing a fire, the feed port is opened, and the fire extinguishing material will enter the airbag through the air outlet pipe under the action of high pressure. Through the one-way valve, this situation can be avoided.

[0020] As an alternative solution of the technical solution of this application document, a one-way air intake mechanism is connected to the top of the pressure-bearing box. The one-way air intake mechanism is used for the airbag to re-enter the gas after releasing the gas so as to be able to withstand multiple explosion impacts.

[0021] By adopting the above technical solution, through the provided one-way air intake mechanism, after one explosion occurs, the airbag deforms due to the impact of high pressure. At this time, due to the elastic performance of the airbag itself, it will recover the deformation. During this process, the outside gas can be inhaled through the one-way air intake mechanism to recover the deformation.

[0022] As an alternative solution of the technical solution of this application document, the one-way air intake mechanism includes a base. An L-shaped pipe is provided in the base. The L-shaped pipe is communicated with the airbag. A stepped pipe is provided inside the base. The stepped pipe is communicated with the L-shaped pipe. A plug is slidably connected in the stepped pipe. A fourth spring is connected to the plug, and the fourth spring is connected to the stepped pipe.

[0023] By adopting the above technical solution, after the airbag is deformed due to the explosion shock, since the airbag itself is made of rubber material, it will recover its elastic deformation. At this time, under the action of the pressure difference between the inside and outside of the airbag, the external gas overcomes the elastic force of the fourth spring and pushes the plug to move, so that a part of the plug moves out of the stepped pipeline, thus connecting the stepped pipeline and the L-shaped pipeline, and the gas can enter the airbag.

[0024] 3. Beneficial effects

[0025] One or more of the technical solutions provided in the technical solution of the present application have at least the following technical effects or advantages:

[0026] 1. The pressure relief port and explosion vent are provided. After the explosion, the explosion pressure generated will be discharged from the explosion vent with relatively poor compressive capacity. Then, the explosion pressure is buffered by multiple bearing plates in the pressure-bearing mechanism, and then discharged through the explosion vent holes opened on the pressure-bearing box. And since the multiple bearing plates are rotatably connected, the overall compressive capacity is further enhanced. Coupled with the first spring, the explosion pressure is converted into elastic potential energy, so as to effectively reduce the explosion pressure. Coupled with the airbag provided, the explosion pressure is further absorbed, and the explosion pressure is converted into the elastic deformation of the airbag. Through the above technical solutions, the explosion shock can be effectively weakened, and multiple explosion shocks can be resisted, greatly reducing the damage degree to the phase change heat exchange energy-saving wall. As a result, the wall assembled by the frame installation and multiple phase change heat exchange energy-saving walls has the function of explosion resistance and explosion reduction, and blocks the explosion shock in the chemical plant building, thus avoiding greater damage caused by the spread of the explosion shock.

[0027] 2. After the explosion occurs, the airbag is impacted by the explosion and deforms, so the internal gas is discharged. The gas can drive the sealing plate and cover plate in the starting mechanism, thus opening the storage tank, and the fire extinguishing material in the storage tank is ejected under high pressure, so as to be able to extinguish the fire.

[0028] 3. The airbag is combined with the one-way air intake mechanism, which can re-intake air after the explosion, and then withstand the impact of multiple explosions. After the explosion occurs, the airbag is squeezed and deformed, and then intakes air through the one-way air intake mechanism, and can buffer and absorb the explosion shock wave during the explosion, so as to achieve the effect of withstanding multiple explosion shocks.

[0044] In the description of this application, it should be noted that unless otherwise clearly specified and limited, the terms "install", "connect", and "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] Refer to Figures 1 to 4, an embodiment of the present application provides a prefabricated explosion-resistant and explosion-reducing wall, including a phase-change heat exchange energy-saving wall 1. A blast vent is provided on the phase-change heat exchange energy-saving wall 1. The blast vent is square, and a blast window 2 is installed on the blast vent. The explosion pressure that the set blast vent can withstand is less than that of other parts of the phase-change heat exchange energy-saving wall 1. Therefore, the explosion air pressure will be discharged from the blast vent. The blast window 2 is made of glass, so that it is convenient for the explosion air pressure to be discharged from the blast window 2 when an explosion occurs. A pressure-bearing mechanism 3 is provided on the outer surface of the phase-change heat exchange energy-saving wall 1. The pressure-bearing mechanism 3 is used to reduce the explosion pressure. The pressure-bearing mechanism 3 includes a pressure-bearing box 31. A pressure relief hole 12 is opened on the surface of the pressure-bearing box 31 away from the phase-change heat exchange energy-saving wall. A plurality of bearing plates 32 that are rotatably connected to each other are arranged inside the pressure-bearing box 31. A plurality of bearing plates 32 are jointly connected to a first spring 36. Two sets of mounting frames 35 are fixed inside the pressure-bearing box 31 up and down. The first spring 36 is connected inside the mounting frame 35. One bearing plate 32 close to the blast window 2 is connected to the first spring 36. An airbag 4 is also provided inside the pressure-bearing box 31. The set of bearing plates 32 are rotatably connected to each other. And with the cooperation of the first spring 36, the explosion pressure is received by the bearing plates 32 and then converted into elastic potential energy, and the explosion pressure is reduced layer by layer through the absorption of the plurality of bearing plates 32, greatly reducing the damage degree to the phase-change heat exchange energy-saving wall. Thus, the wall assembled by frame installation and a plurality of phase-change heat exchange energy-saving walls has the functions of explosion resistance and explosion reduction, and blocks the explosion impact in the chemical plant building.

[0046] Refer to Figure 2 , Figure 5 , a storage box 6 is also provided on the outer surface of the phase-change heat exchange energy-saving wall 1. Fire extinguishing materials are arranged inside the storage box 6. The selected fire extinguishing material is dry powder fire extinguishing agent. The inside of the storage box 6 is in a high-pressure environment. A transmission box 7 is provided above the storage box 6. An opening mechanism 5 is arranged inside the transmission box 7. The airbag 4 is connected to the opening mechanism 5. When an explosion occurs, the airbag 4 is squeezed, so that the internal gas drives the opening mechanism 5 to act and then opens the storage box 6, so that the fire extinguishing materials in the storage box 6 are ejected;

[0047] Refer to Figure 5 , Figure 6As shown, the opening mechanism 5 includes an air outlet pipe 52. One end of the air outlet pipe 52 is communicated with the airbag 4, and the other end of the air outlet pipe 52 is connected to a connection box 10. A sliding plate 11 is slidably connected inside the connection box 10. The opening mechanism 5 includes a sealing plate 54 and a cover plate 504. An air outlet is provided on the side wall of the transmission box 7, and a spray pipe 51 is connected inside the air outlet. A feeding port 8 is provided at the bottom of the transmission box 7. The sealing plate 54 and the cover plate 504 respectively correspond to the air outlet and the feeding port 8. The gas in the airbag 4 pushes the sliding plate 11 to move, and the sliding plate 11 further drives the sealing plate 54 and the cover plate 504 to move. By the gas in the airbag 4 pushing the sliding plate 11 in the connection box 10 to move, the sliding plate 11 further drives the sealing plate 54 and the cover plate 504 to move, so as to open the feeding port 8 and the air outlet. The fire extinguishing material in the storage box 6 is discharged successively through the feeding port 8 and the air outlet under the push of high-pressure gas.

[0048] Referring to Figure 2 and Figure 4 In this regard, the embodiment of the present application provides a prefabricated anti-explosion and explosion mitigation wall. The pressure-bearing mechanism 3 further includes fixed rails 34. Two groups of fixed rails 34 are respectively fixed on the upper and lower bottoms of the pressure-bearing box 31. A plurality of bearing plates 32 are slidably connected to the fixed rails 34. The provided fixed rails 34 can effectively limit the bearing plates 32. A connecting unit 33 is rotatably connected between the plurality of bearing plates 32. The connecting unit 33 is composed of a plurality of connecting rods that are rotatably connected to each other. The provided connecting unit 33 can connect the plurality of bearing plates 32 into a whole, so as to improve the overall compressive strength and further be able to absorb more explosion impacts.

[0049] Referring to Figure 5 and Figure 6 In this regard, the embodiment of the present application provides a prefabricated anti-explosion and explosion mitigation wall. A slide rail 53 is provided inside the side wall of the transmission box 7. The sealing plate 54 is slidably connected inside the slide rail 53. A second spring 55 is connected to the sealing plate 54, and the other end of the second spring 55 is connected to the transmission box 7. A push rod 56 is fixedly connected to the sliding plate 11. The push rod 56 extends into the transmission box 7 and is located above the sealing plate 54. By driving the push rod 56 to move through the sliding plate 11, the push rod 56 further drives the sealing plate 54 to move, so as to open the air outlet, and the spray pipe 51 can spray out the fire extinguishing material.

[0050] Referring to Figure 5 and Figure 6, an embodiment of the present application provides a prefabricated anti-explosion and explosion mitigation wall. The cover plate 504 is slidably connected to the bottom of the transmission box 7, and a third spring 505 is connected to the cover plate 504. The other end of the third spring 505 is connected to the transmission box 7. A first triangular frame 501 is connected to the sealing plate 54, and a second triangular frame 502 is fixedly connected to the cover plate 504. The first triangular frame 501 and the second triangular frame 502 correspond to each other. A pulley is provided on the hypotenuse of the first triangular frame 501, and the provided pulley can reduce the friction when contacting the second triangular frame 502. A pull rod 503 is connected to the second triangular frame 502, and the pull rod 503 extends to the outside of the transmission box 7.

[0051] Refer to Figure 3 , Figure 5 and Figure 6 , the provided opening mechanism 5 is started by the gas in the airbag 4. The specific steps are as follows: the airbag 4 deforms under the action of the explosion pressure, and the gas in the airbag 4 enters the connection box 10 through the air outlet pipe 52, thereby pushing the slide plate 11 in the connection box 10 to move. The push rod 56 connected to the slide plate 11 further drives the sealing plate 54 to move. As the sealing plate 54 moves, the air outlet covered by the sealing plate 54 is opened. As the sealing plate 54 continues to move, the first triangular frame 501 on the sealing plate 54 moves synchronously. When the first triangular frame 501 moves to the position of the second triangular frame 502, it pushes the second triangular frame 502 to move. The second triangular frame 502 drives the cover plate 504 connected thereto to move synchronously, and the feed inlet 8 covered on the cover plate 504 is opened, so that the fire extinguishing material in the storage tank 6 is ejected under the action of high pressure and finally ejected from the spray pipe 51.

[0052] Refer to Figure 2 and Figure 5 , an embodiment of the present application provides a prefabricated anti-explosion and explosion mitigation wall. The storage tank 6 and the transmission box 7 are communicated through the feed inlet 8, and two transmission boxes 7 are provided and distributed on both sides of the pressure-bearing box 31. A one-way valve is provided on the air outlet pipe 52, and the one-way valve only allows the gas in the airbag 4 to be discharged. The provided one-way valve prevents the fire extinguishing material in the storage tank 6 from entering the airbag 4 through the air outlet pipe 52 after the opening mechanism 5 is opened.

[0053] Refer to Figure 10 and Figure 11 , an embodiment of the present application provides a prefabricated anti-explosion and explosion mitigation wall. A one-way air intake mechanism 9 is connected to the top of the pressure-bearing box 31, and the one-way air intake mechanism 9 is used for the airbag 4 to re-enter the gas after releasing the gas so as to be able to withstand multiple explosion impacts.

[0054] Refer to Figure 10 and Figure 11, an embodiment of the present application provides a prefabricated explosion-resistant and explosion-reducing wall. The unidirectional air intake mechanism 9 includes a base 91. An L-shaped pipe 92 is provided in the base 91. The L-shaped pipe 92 is communicated with the airbag 4. A stepped pipe 93 is provided inside the base 91. The stepped pipe 93 is communicated with the L-shaped pipe 92.

[0055] Refer to Figure 10 and Figure 11 , an embodiment of the present application provides a prefabricated explosion-resistant and explosion-reducing wall. A plug 94 is slidably connected in the stepped pipe 93. A fourth spring 95 is connected to the plug 94. The fourth spring 95 is connected to the stepped pipe 93.

[0056] Refer to Figure 10 and Figure 11 , the provided unidirectional air intake mechanism 9 can, after the airbag 4 deforms, due to its own elastic properties, after restoring elastic deformation, external gas enters the airbag 4, and the gas in the airbag 4 cannot be discharged from the unidirectional air intake mechanism 9. The purpose of this setting is not to affect the opening of the sealing plate 54 and the cover plate 504 in the opening mechanism 5 by the airbag 4. When the unidirectional air intake mechanism 9 and the airbag 4 restore elastic deformation, with the pressure difference inside and outside the airbag 4, external gas overcomes the gravity of the plug 94 and the elastic force of the fourth spring 95, thereby pushing the plug 94 into the L-shaped pipe 92. At this time, the L-shaped pipe 92 is communicated with the stepped pipe 93, and at this time, external gas can enter the airbag 4.

[0057] Working principle: When the present invention is assembled, first install and fix the phase change energy-saving wall to the frame respectively, and then install and fix the assembled whole in the chemical plant building through the frame;

[0058] When an explosion danger suddenly occurs in a chemical plant, the provided pressure-bearing mechanism 3 uses the action of multiple pressure plates 32 and the first spring 36 to buffer the explosion impact, convert the explosion impact force into the elastic potential energy of the spring, and then the explosion shock wave continues to impact the airbag 4. The airbag 4 undergoes elastic deformation, thereby further absorbing the explosion impact force. The remaining explosion shock wave is discharged through the pressure relief hole 12. At the same time, due to the deformation of the airbag 4, the internal gas is discharged to the opening mechanism 5, and the opening mechanism 5 thus sprays the dry powder fire extinguishing agent in the storage tank 6 with gas as the power, thereby extinguishing the fire.

[0059] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
