Description

Technical Field

[0001] The utility model relates to the technical field of hydrofluoric acid storage, in particular to an anhydrous hydrofluoric acid storage device with a temperature reduction function. Background Art

[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 and can strongly corrode metals, glass and silicon-containing objects.

[0003] The existing anhydrous hydrofluoric acid storage tanks are horizontal or vertical storage tanks, generally placed in outdoor open-air tank areas, and are made of carbon steel. The boiling point of anhydrous hydrogen fluoride is 19.5°C. Although the tank body is covered with cold-insulating rubber and plastic cotton, it is exposed to high temperature outdoor environments for a long time, especially in the summer in the south where the outdoor temperature is above 30°C. The temperature inside the tank often exceeds 20°C, causing the liquid in the tank to vaporize and the pressure to rise, which poses a safety risk. If the pressure is frequently discharged, it will cause waste.

[0004] In view of this, the present application proposes an anhydrous hydrofluoric acid storage device with a cooling function. Utility Model Content

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 3 As shown, a preferred embodiment of the utility model is a storage device for anhydrous hydrofluoric acid with a cooling function, comprising a tank body 1, a sleeve body 2 is provided on the outside of the tank body 1, a heat insulating support layer 3 is provided between the outer side of the tank body 1 and the inner side of the sleeve body 2, the heat insulating support layer 3 comprises a heat insulating member 301 extending axially along the tank body 1 and a plurality of cavities 302 formed by the heat insulating support layer 3 and separated by the heat insulating member 301, the cavity 302 is provided with a cooling component on the side facing the tank body 1, the cooling component comprises a coil 4 arranged on the outside of the tank body 1, the coil 4 is filled with coolant, so as to achieve the effect of cooling the hydrofluoric acid storage tank, and at the same time, the temperature of the anhydrous hydrofluoric acid storage tank can be kept warm by setting the heat insulating support layer, so that the temperature of the anhydrous hydrofluoric acid storage tank is not easy to rise, thereby facilitating the storage of hydrofluoric acid.

[0025] As a preferred embodiment of the utility model, it may also have the following additional technical features: the heat insulating member 301 includes a plurality of protrusions 8 evenly distributed around a center line, the protrusions 8 protrude away from the tank body 1, and the protrusions 8 include a convex top 801 and a lower abutment 802, the convex top 801 abuts against the inner side of the sleeve 2, the lower abutment 802 is parallel to the axial direction of the tank body 1 and abuts against the outer side of the tank body 1, and the adjacent lower abutment 802 of the adjacent protrusions 8 are connected or overlapped. As a result, the heat insulating member 301 can be stably supported between the tank body 1 and the sleeve 2, so that the tank body 1 has a good thermal insulation effect.

[0026] In this embodiment, the lower abutment 802 is spaced apart from the coil 4 , so that the coolant in the coil 4 can effectively cool the anhydrous hydrofluoric acid in the tank 1 .

[0027] In this embodiment, the side of the protrusion 8 facing away from the tank body 1 is inclined in the same circumferential direction as the radial direction of the casing 2; and the side of the protrusion 8 facing away from the inclined direction of the adjacent protrusions 8 overlaps with the side of the other protrusion 8 facing the tank body 1 in the radial direction of the casing; and the lower abutment 802 of the protrusion 8 is inclined in the same circumferential direction as the radial direction of the casing 1. Thus, the heat insulating member 3 can stably support the casing 2 to prevent the casing from collapsing, and at the same time, the temperature of the anhydrous hydrofluoric acid storage tank can be kept warm, so that the temperature of the anhydrous hydrofluoric acid storage tank is not easy to rise, thereby facilitating the storage of hydrofluoric acid.

[0028] In this embodiment, the heat insulating member 301 is made of elastic material, so that the tank body has a buffering effect, effectively preventing the tank body from tipping over when it is impacted by the outside world.

[0031] By arranging a casing 2 and a heat-insulating support layer 3 on the outside of the tank body 1, the temperature of the anhydrous hydrofluoric acid storage tank can be kept warm, so that the temperature of the anhydrous hydrofluoric acid storage tank is not easy to rise. The casing 2 can protect the heat-insulating support layer 3, so that the heat-insulating support layer 3 is not easily damaged by the outside, thereby extending the service life of the heat-insulating support layer 3.
