Description

Technical Field

[0001] The invention belongs to the technical field of building design and relates to an explosion-proof and pressure-relieving plant. Background Art

[0002] There are often flammable and explosive substances in laboratory buildings, such as fuel gasoline, methane, hydrogen, etc. In the construction of such laboratory buildings, according to the relevant regulations on building design, pressure relief facilities should be installed in buildings with explosion hazards or parts of buildings with explosion hazards.

[0003] Especially hydrogen, which is a secondary energy with abundant sources, green and low carbon, and wide application. It can be used as fuel cell power generation, applied in automobiles, trains, ships, aviation and other fields, or it can be used alone as fuel gas or chemical raw material for production. At the same time, it can also be mixed with hydrogen in natural gas pipelines for combustion and applied to building heating. In the context of promoting carbon reduction, the number of hydrogen energy development policies and construction projects has increased rapidly. However, safety is the basis and inherent requirement for the industrialization of hydrogen energy. Hydrogen is the lightest gas, and its "weight" is less than one-fourteenth of that of air. It is a Class A combustible gas with wide combustion and explosion limits (volume concentration 4.0% to 75.6%), low minimum ignition energy (0.019mJ), fast flame propagation speed, and high explosion intensity. When detonation occurs, the flame speed can reach more than 2000m / s, and the instantaneous pressure is 40 times the original pressure. Therefore, safety has become the primary concern of hydrogen energy application.

[0004] In the construction of this type of flammable and explosive plant, pressure relief is one of the necessary measures to reduce the risk of explosion. According to the relevant regulations on building design, the pressure relief area calculation formula is: A = 10CV 2 / 3 , where: A—represents the pressure relief area (m 2 ), V represents the volume of the pressure relief space required in the plant (m 3 ), C represents the pressure relief ratio (m 2 / m 3 ). Among them, the pressure relief ratio of hydrogen is the highest among conventional materials, which is ≥0.250m 2 / m 3 , while the pressure relief ratio of commonly used fuels such as gasoline and methane is ≥0.110m 2 / m 3 Therefore, when the plant volume is constant, the hydrogen pressure relief area required is much larger.

[0005] With the widespread application of high-efficiency energy such as hydrogen energy, the demand for pressure relief and explosion prevention in flammable and explosive factories has been raised. Finding a more suitable pressure relief solution for flammable and explosive factories has become a technical problem that needs to be solved urgently. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide an explosion-proof and pressure-relief plant, which effectively solves the technical problems of pressure relief and explosion resistance, increases the pressure relief area, and improves the applicability and layout flexibility of the plant.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] An explosion-proof and pressure-relief plant, comprising an explosion-proof zone arranged at the bottom of the outer wall in the plant, wherein the storey height of the explosion-proof zone is smaller than the storey height of the plant; the area from the top of the explosion-proof zone to the top of the plant and the area between two adjacent explosion-proof zones are pressure-relief zones.

[0009] Optionally, a side of the explosion-proof zone close to the pressure relief zone is sequentially configured as a first explosion-proof wall and a first explosion-proof floor.

[0010] Optionally, the exterior wall in contact with the pressure relief zone is set as a pressure relief exterior wall, and the top of the pressure relief zone is set as a pressure relief roof.

[0011] Optionally, a second explosion-proof wall is provided in the pressure relief zone to separate the pressure relief zone into two independent areas.

[0012] Optionally, a side of the explosion-proof zone close to the pressure relief zone is connected through a door lobby.

[0013] Optionally, an explosion-proof and fireproof door is provided on the side of the door lobby close to the pressure relief zone.

[0014] Optionally, the pressure relief zone and the explosion-proof zone are isolated as two independent areas by the first explosion-proof wall and the first explosion-proof floor slab that are connected to each other, so as to prevent the flammable and explosive gas in the pressure relief zone from entering the explosion-proof zone.

[0015] Optionally, the pressure relief zone is a test chamber.

[0016] Optionally, the pressure relief area is a production area.

[0017] The beneficial effects of the present invention are:

[0018] In the prior art, rooms containing flammable and explosive gases are arranged close to the outer wall, and the roof and side walls are used as explosion relief surfaces to meet the pressure relief area requirements. It is difficult to avoid that the rooms are facing crowded places and traffic roads, which poses a safety risk. The present invention, however, arranges the explosion-proof zone at the lower part close to the outer wall, uses only the upper part of the explosion-proof zone as the pressure relief zone, and arranges this part of the outer wall as the pressure relief outer wall, thereby reducing the risk of facing crowded places and traffic roads during pressure relief and improving the flexibility of the layout of plants involving flammable and explosive gases.

[0019] The internal layout of the plant of the present invention, on the one hand, effectively separates the explosion-proof area from the pressure relief area, and on the other hand, also meets the pressure relief area requirements of the pressure relief area. This solution has a compact layout, high space utilization, and relatively concentrated pipeline layout. On the basis of the same functional requirements, it saves plant space and effectively saves plant construction costs. The explosion-proof area can provide a better working environment and safety near the outside of the plant. The overall layout achieves the characteristics of reasonable functional layout, smooth logistics and personnel flow, and good visitability.

[0020] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0033] See also Figure 1 to Figure 4 , is an explosion-proof pressure relief plant, including an explosion-proof zone 1 set at the bottom of the outer wall in the plant, the floor height of the explosion-proof zone 1 is less than the floor height of the plant; the area from the top of the explosion-proof zone 1 to the top of the plant, and the area between two adjacent explosion-proof zones 1 is the pressure relief zone 2. In practical applications, the pressure relief zone 2 is usually used as an area for the production and testing of flammable and explosive gases.

[0034] The floor height of explosion-proof zone 1 is smaller than that of the plant building. The purpose is to use the space above explosion-proof zone 1 as a gathering area for flammable and explosive gases and a pressure relief expansion area, so as to facilitate pressure relief toward the side wall or roof of the plant building. The area of ​​pressure relief zone 2 near the outside of the plant building is also increased, which can be used as the outside area of ​​pressure relief to meet the required pressure relief area requirements.

[0035] The side of the explosion-proof zone 1 close to the pressure relief zone 2 is sequentially provided with the first explosion-proof wall 11 and the first explosion-proof floor 12; the outer wall in contact with the pressure relief zone 2 is provided with the pressure relief outer wall 21, and the top of the pressure relief zone 2 is provided with the pressure relief roof 22. The explosion-proof zone 1 located at the bottom of the outer wall of the factory building separates the pressure relief zone 2 from the outdoor crowded area, roads, etc., and the pressure relief area is limited to the top of the outer wall and the roof, which reduces the explosion risk caused to outdoor personnel and roads during pressure relief and improves the safety of the factory building.

[0036] When the explosion-proof zone 1 needs to be connected with the pressure relief zone 2, a door vestibule 6 which plays a buffering role such as separation and sound insulation is set on the side of the explosion-proof zone 1 close to the pressure relief zone 2, and an explosion-proof fire door is required to be set on the side of the door vestibule 6 close to the pressure relief zone 2; when the explosion-proof zone 1 is not connected with the pressure relief zone 2, the pressure relief zone 2 and the explosion-proof zone 1 are isolated as two independent areas by the connected first explosion-proof wall 11 and the first explosion-proof floor 12 to prevent the flammable and explosive gases in the pressure relief zone 2 from entering the explosion-proof zone 1.

[0037] The explosion-proof construction measures of the factory building include material selection, special structural design, etc. In terms of material selection, high-strength, impact-resistant and explosion-proof materials should be selected; high-strength steel or reinforced concrete structures should be used for supporting structures such as walls and columns to ensure sufficient bearing capacity. The floor material selection should meet the requirements of explosion resistance and fire prevention.

[0038] In terms of structural design, the wall thickness and reinforcement need to be determined according to the building's function and explosion-proof level. Sufficient wall thickness and reasonable reinforcement can effectively resist the shock wave generated by the explosion; other explosion-proof measures of the wall part are set according to conventional methods.

[0039] Example 1

[0040] like Figure 1 , 2 As shown, the interior of the factory building is a pressure relief zone 2 with a "T"-shaped cross-section, and explosion-proof zones 1 arranged at the bottom of the outer walls on both sides of the factory building, wherein the explosion-proof zone 1 on one side is connected through a door lobby 6 arranged between the explosion-proof zone 1 and the pressure relief zone 2; the explosion-proof zone 1 on the other side is not connected to the pressure relief zone 1, and the two are isolated as two independent areas by a connected first explosion-proof wall 11 and a first explosion-proof floor 12 to prevent the flammable and explosive gas in the pressure relief zone 2 from entering the explosion-proof zone 1.

[0041] The walls and floor slabs of the explosion-proof zone 1 on the side close to the pressure relief zone 2 are both provided with explosion-proof structures, and the outer walls and roof of the factory building close to the pressure relief zone 2 are the pressure relief outer walls 21 and the pressure relief roof 22.

[0042] In this embodiment, relevant tests involving hydrogen energy are carried out in the plant, wherein the pressure relief zone 2 is a hydrogen-related zone, and the explosion-proof zone 1 is a non-hydrogen-related zone.

[0043] Example 2

[0044] like Figure 3 , 4 As shown, a second explosion-proof wall 3 is provided in the pressure relief zone 2 for dividing it into two independent areas, dividing the interior of the plant into two symmetrically arranged "Г"-shaped pressure relief zones 2 and an explosion-proof zone 1 arranged at the bottom of the outer walls on both sides of the plant; an explosion-proof wall is provided between the two symmetrical pressure relief zones 2. The two explosion-proof zones 1 are connected to the pressure relief zone 2 through a door 6 provided between the explosion-proof zone 1 and the pressure relief zone 2.

[0045] The walls and floor slabs of the explosion-proof zone 1 close to the hydrogen-related zone are provided with explosion-proof structures, and the outer walls and roof of the plant building close to the pressure relief zone 2 are the pressure relief outer walls 21 and the pressure relief roof 22.

[0046] In this embodiment, relevant tests involving hydrogen energy are carried out in the plant, wherein the pressure relief zone 2 is a hydrogen-related zone, and the explosion-proof zone 1 is a non-hydrogen-related zone.

[0047] Example 3

[0048] like Figure 5 , 6 As shown, on the basis of the above-mentioned embodiment 2, a channel 4 is arranged at the lower part of the second explosion-proof wall 3, and a second explosion-proof wall 3 connected to the roof of the factory building is arranged above the channel 4, and the pressure relief zone 2 is divided into two separate areas by the second explosion-proof wall 3 and the channel 4; the side of the channel 4 close to the pressure relief zone 2 is successively arranged with a third explosion-proof wall 41 and a third explosion-proof floor 42.

[0049] The channel 4 can be a logistics channel 4, which is arranged at the bottom of the explosion-proof wall between two symmetrical pressure relief zones 2, dividing the two symmetrical pressure relief zones 2 into two "T"-shaped pressure relief zones 2; the logistics channel 4 is used to transport goods. Along the axial direction of the logistics channel 4, an unmanned equipment room 5 is arranged between the pressure relief zones 2 to divide the pressure relief zones 2 into multiple hydrogen-related test laboratories. In order to connect the explosion-proof zone 1 and the hydrogen-related test laboratory, a door vestibule 6 is arranged. The door vestibule 6 can be arranged in the equipment room 5 near the corner of the hydrogen-related test laboratory and the explosion-proof zone 1, or in the pressure relief zone 2; the logistics channel 4 is respectively connected to the equipment room 5 and the hydrogen-related test laboratory. A Class A fire door is arranged at the connection between the hydrogen-related test laboratory and the logistics channel 4.

[0050] The explosion-proof zone 1 can be a whole large area or divided into multiple functional areas according to the functionality of the actual area. In the present embodiment, it is divided into a corridor 13 and a control room 14 , and the vestibule 6 is connected to the control room 14 .

[0051] A plurality of hydrogen-related test laboratories are provided, each of which is adjacent to the logistics channel 4 for the convenience of goods entering and exiting, and each of which is adjacent to the control room 14 for the convenience of real-time observation during the test, and an equipment room 5 is provided, in which detection equipment and power distribution equipment can be arranged. The internal structure of the plant in this embodiment makes the logistics and personnel flow relatively independent to avoid mutual influence.

[0052] The present invention divides the internal layout of the plant into a pressure relief zone 2 and an explosion-proof zone 1. In view of the situation where the explosion-proof zone 1 needs to be arranged against the outer wall of the plant and the pressure relief zone 2 needs to be arranged against the inner side of the plant, the floor height of the explosion-proof zone 1 is made lower than the indoor floor height of the plant, and the space above the explosion-proof zone 1 is included in the pressure relief zone 2. The area of ​​the pressure relief zone 2 against the outer side of the plant is increased, thereby meeting the pressure relief area requirement of the pressure relief zone 2. The present invention solves the difficulty that the conventional explosion-proof pressure relief plant can only arrange the pressure relief zone 2 against the outer wall, which leads to inconvenience in the process, logistics, and pipeline layout, improves the flexibility of the internal layout of the hydrogen-related plant, and also improves the safety of explosion-proof pressure relief.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
