Description

Technical Field

[0001] This invention relates to the field of hydrofluoric acid production equipment, and more particularly to a leak-proof hydrofluoric acid production equipment. Background Technology

[0002] Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas. It is a clear, colorless, fuming, corrosive liquid with a strong, pungent odor. It is extremely corrosive, severely damaging metals, glass, and silicon-containing materials. Inhalation of its vapors or skin contact can cause burns that are difficult to heal. Therefore, the management and storage of hydrofluoric acid are crucial. When hydrofluoric acid leaks, if it is not dealt with immediately, it will cause widespread pollution to the surrounding environment. The larger the leak, the greater the threat to the lives of workers and firefighters. However, existing hydrofluoric acid production facilities cannot effectively control leaks in a timely manner, making it difficult for firefighters to handle leaks. Summary of the Invention

[0003] In order to overcome the shortcomings of existing hydrofluoric acid production equipment that cannot effectively control hydrofluoric acid leakage in the first instance, this invention provides a leak-proof hydrofluoric acid production equipment.

[0004] This invention describes a leak-proof hydrofluoric acid production equipment, comprising a base platform, a lifting mechanism, a lifting plate, an outer ring plate, an annular nozzle, a fixed frame, a sliding support, and a reaction vessel. The lifting mechanism is installed in the middle of the base platform; a lifting plate is fixedly connected to the lifting end of the lifting mechanism; the lifting plate is slidably connected to the base platform; a fixed frame is fixedly connected to the middle of the base platform; the lifting plate is slidably connected to the fixed frame; a sliding support is fixedly connected to the lifting plate; the sliding support is slidably connected to the fixed frame; a reaction vessel is installed on the sliding support; an outer ring plate is fixedly connected to the outer edge of the base platform; an annular nozzle is fixedly connected inside the outer ring plate; a spray groove structure corresponding to the spray holes of the annular nozzle is formed on the outer ring plate; an inlet pipe is connected to the annular nozzle.

[0005] As a preferred embodiment of the present invention, the upper surface of the outer ring plate is configured as an inwardly and downwardly inclined annular slope structure.

[0006] As a preferred embodiment of the present invention, a storage bag is placed on the inner lower side of the outer ring plate; the storage bag is filled with lime; and the inner ring surface of the storage bag is provided with a protruding structure that penetrates the outer ring plate and the base.

[0007] As a preferred embodiment of the present invention, an elastic hook is fixedly connected to the outer ring surface of the lifting plate.

[0008] As a preferred embodiment of the present invention, a material gathering groove structure is formed around the upper surface edge of the lifting plate.

[0009] As a preferred embodiment of the present invention, the outer wall of the material collection tank is provided with a ring-shaped side plate; a drain net is connected to the ring-shaped side plate; an inner ring cavity structure is opened at the bottom of the lifting plate; after the hydrofluoric acid flowing into the material collection tank is neutralized and reacted with lime, the waste liquid flows into the inner ring cavity through the drain net.

[0010] As a preferred embodiment of the present invention, an annular waste liquid pipe is fixedly connected to the bottom of the base; a suction pipe is connected to the annular waste liquid pipe; and several guide pipes are connected between the annular waste liquid pipe and the inner annular cavity.

[0011] As a preferred embodiment of the present invention, the annular side plate is slidably connected to the lifting plate; the lifting plate is connected to a drive assembly that drives the annular side plate to rotate.

[0012] The drive assembly consists of a gear ring, a motor, and a spur gear; the gear ring is fixedly connected to the annular side plate; the motor is fixedly connected inside the lifting plate; the output shaft of the motor is fixedly connected to the spur gear; the spur gear meshes with the gear ring.

[0013] As a preferred embodiment of the present invention, a stirring plate is fixedly attached to the annular side plate.

[0014] As a preferred embodiment of the present invention, the number of stirring plates corresponds to the number of leakage nets; the stirring plates are configured with an arc-shaped structure and cover the leakage nets.

[0015] This invention describes a leak-proof hydrofluoric acid production equipment. When a hydrofluoric acid leak occurs in the reactor, the operator quickly controls the elevator to move the lifting plate downwards. The lifting plate moves the sliding support and the reactor downwards, causing the reactor to partially sink into the bottom platform. This reduces the distance the leaking hydrofluoric acid travels outwards, allowing it to accumulate in the bottom platform and effectively control the extent of leakage. An annular nozzle is installed along the outer edge of the bottom platform to continuously spray fire-fighting liquid into the reactor, diluting the leaked hydrofluoric acid and reducing its evaporation, thereby minimizing environmental pollution.

[0016] This solution addresses the technical problem that existing hydrofluoric acid production facilities are unable to effectively control hydrofluoric acid leaks in a timely manner when such leaks occur. Attached Figure Description

The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0028] Example 1

[0029] A leak-proof hydrofluoric acid production device, such as Figures 1-8As shown, the system includes a base platform 1, a lift 11, a lifting plate 12, an outer ring plate 2, an annular nozzle 21, a fixed frame 3, a sliding support 4, and a reaction vessel 5. The lift 11 is installed in the middle of the base platform 1. The lifting plate 12 is fixedly connected to the lifting end of the lift 11. The lifting plate 12 is slidably connected to the base platform 1. The fixed frame 3 is fixedly connected to the middle of the base platform 1. The lifting plate 12 is slidably connected to the fixed frame 3. The sliding support 4 is bolted to the lifting plate 12. The sliding support 4 is slidably connected to the fixed frame 3. The reaction vessel 5 is installed on the sliding support 4. During the downward movement of the lift 11 and the lifting plate 12, the lifting plate 12 moves the sliding support 4 and the reaction vessel 5 downward, causing the reaction vessel 5 to partially sink into the base platform 1. The outer ring plate 2 is fixedly connected to the outer edge of the base platform 1. The annular nozzle 21 is fixedly connected inside the outer ring plate 2. Several spray channels 20 structures corresponding to the spray holes of the annular nozzle 21 are opened on the outer ring plate 2. An inlet pipe 210 is connected to the annular nozzle 21.

[0030] like Figure 2 As shown, the upper surface of the outer ring plate 2 is configured as an inward and downward inclined annular slope structure, so that the sprayed hydrofluoric acid flows along the annular slope of the outer ring plate 2 as much as possible to the lifting plate 12, avoiding hydrofluoric acid from flowing into external sewers and other areas, causing environmental pollution.

[0031] like Figures 4-6 As shown, a storage bag 22 is placed on the inner lower side of the outer ring plate 2; the storage bag 22 is filled with lime; the inner ring surface of the storage bag 22 is provided with several protrusions 221 that penetrate the outer ring plate 2 and the base 1; during the downward movement of the lifting plate 12, the protrusions 221 of the storage bag 22 are scratched, allowing the lime in the storage bag 22 to leak onto the surface of the lifting plate 12; several elastic hooks 13 are welded around the outer ring surface of the lifting plate 12, and during the descent of the lifting plate 12, the protrusions 221 of the storage bag 22 are scratched by the elastic hooks 13, improving the success rate of scratching the protrusions 221.

[0032] like Figure 2 , Figures 6-8 As shown, a material collection trough 120 structure is formed around the upper surface edge of the lifting plate 12. The lime leaking from the storage bag 22 accumulates in the material collection trough 120 of the lifting plate 12, improving the contact effect between hydrofluoric acid and lime. A ring-shaped side plate 6 is provided on the outer wall of the material collection trough 120. Several leakage nets 61 are connected to the ring-shaped side plate 6. An inner ring cavity 121 structure is formed at the inner bottom of the lifting plate 12. After the hydrofluoric acid flowing into the material collection trough 120 is neutralized and reacted with the lime, the waste liquid flows into the inner ring cavity 121 through the leakage nets 61. A ring-shaped waste liquid pipe 7 is fixed to the bottom of the base 1. A suction pipe 70 is connected to the ring-shaped waste liquid pipe 7. Several guide pipes 71 are connected between the ring-shaped waste liquid pipe 7 and the inner ring cavity 121. The waste liquid flowing into the inner ring cavity 121 enters the ring-shaped waste liquid pipe 7 through the guide pipes 71 and is recovered outward through the suction pipes 70.

[0033] Leakage prevention measures for this leak-proof hydrofluoric acid production equipment:

[0034] The base platform 1 and outer ring plate 2 of this leak-proof hydrofluoric acid production equipment are installed in the ground. The upper surfaces of the base platform 1 and outer ring plate 2 are flush with the ground. The liquid inlet pipe 210 is connected to the fire-fighting pipeline, and the hydrofluoric acid production work is carried out through the reaction vessel 5.

[0035] When hydrofluoric acid leakage occurs in reactor 5, the staff quickly activates the elevator 11. The lifting end of the elevator 11 moves the lifting plate 12 downward, which in turn moves the sliding support 4 and reactor 5 downward, causing reactor 5 to partially sink into the base platform 1. Figure 9 As shown, when hydrofluoric acid leaks out from any position in the reactor 5, it is intercepted by the inner wall of the base 1, which limits the spray distance of the hydrofluoric acid sprayed from the reactor 5. The hydrofluoric acid sprayed from the reactor 5 is collected between the base 1 and the lifting plate 12, thus effectively controlling the range of hydrofluoric acid leakage from the reactor 5 and avoiding large-scale environmental pollution caused by hydrofluoric acid leakage.

[0036] After the reactor 5 sinks into the bottom platform 1, the external fire-fighting pipeline delivers fire-fighting fluid to the annular nozzle 21 through the inlet pipe 210. The fire-fighting fluid is sprayed in reverse from the nozzle of the annular nozzle 21 through the spray tank 20 back to the reactor 5, so as to achieve all-round spraying of fire-fighting fluid onto the reactor 5. The fire-fighting fluid promptly dilutes the hydrofluoric acid leaking from the reactor 5, reduces the amount of hydrofluoric acid volatilized, and thus reduces the degree of hydrofluoric acid pollution to the external environment.

[0037] Neutralization treatment for this leak-proof hydrofluoric acid production equipment:

[0038] The suction tube 70 is connected to an external waste liquid collection and suction device.

[0039] As the lifting end of the elevator 11 moves the lifting plate 12 downward, the lifting plate 12 uses the elastic hook 13 to puncture the protrusion 221 of the storage bag 22. When the lifting plate 12 moves downward to below the protrusion 221, the lime in the storage bag 22 leaks downward through the punctured part of the protrusion 221 into the aggregate tank 120 of the lifting plate 12. The hydrofluoric acid that accumulates in the lifting plate 12 flows into the aggregate tank 120 in sequence to neutralize the lime. At the same time, the fire-fighting liquid sprayed from the annular nozzle 21 sprays downward from above the lifting plate 12 to absorb the heat released by the neutralization reaction of hydrofluoric acid and lime, and to cool down the ambient temperature around the leak-proof hydrofluoric acid production equipment, so as to prevent the firefighters who arrive later from being burned by the heat released by the neutralization reaction of hydrofluoric acid and lime.

[0040] The waste liquid formed after the neutralization reaction of hydrofluoric acid and lime enters the annular waste liquid pipe 7 through the leakage net 61 and the guide pipe 71. At the same time, the external waste liquid collection and suction equipment performs suction and collection work on the waste liquid accumulated in the annular waste liquid pipe 7 through the suction pipe 70.

[0041] Example 2

[0042] like Figures 1-8 As shown, based on Embodiment 1, the annular side plate 6 and the lifting plate 12 are slidably connected in this embodiment; a drive assembly for rotating the annular side plate 6 is connected to the lifting plate 12; the drive assembly consists of a gear ring 81, a motor 82 and a spur gear 83; the gear ring 81 is fixedly connected to the annular side plate 6; the motor 82 is bolted to the inside of the lifting plate 12; the output shaft of the motor 82 is fixedly connected to the spur gear 83; the spur gear 83 meshes with the gear ring 81.

[0043] During the neutralization reaction of hydrofluoric acid and lime in the aggregate tank 120, some of the lime will solidify into lumps, causing blockage of the adjacent drain net 61. At this time, the output shaft of the motor 82 drives the spur gear 83 to rotate. The spur gear 83 meshes with the toothed ring 81, driving the annular side plate 6 and the drain net 61 connected to it to rotate. This allows the waste liquid accumulated in the aggregate tank 120 to flow downward through the unblocked drain net 61 in a timely manner, avoiding the phenomenon that a large amount of waste liquid accumulates in the aggregate tank 120, causing more lime to solidify into lumps, resulting in more drain nets 61 being blocked, thus preventing a vicious cycle from occurring.

[0044] Example 3

[0045] like Figures 1-8 As shown, based on embodiment 2, this embodiment has several stirring plates 62 welded around the annular side plate 6. During the rotation of the annular side plate 6 and the stirring plates 62, the lime accumulated in the material tank 120 is continuously stirred. The number of stirring plates 62 corresponds to the number of liquid leakage nets 61. The stirring plates 62 are set as arc-shaped structures and cover the liquid leakage nets 61.

[0046] During the process of stirring the lime by the stirring plate 62, the lime will not accumulate on the liquid leakage net 61. When the annular side plate 6 continuously drives the stirring plate 62 to rotate, under the stirring and pushing of the lime, the liquid leakage net 61 covered by the stirring plate 62 will continuously have gaps that are not covered by lime, reducing the phenomenon of the liquid leakage net 61 being blocked by lime, and allowing the waste liquid in the material tank 120 to flow smoothly downward through the liquid leakage net 61.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
