Problems solved by technology
But the above operation is very cumbersome, and when the leakage is small, the phenomenon of white smoke is not obvious
[0006] After the unloading is completed, it is written in the technology, and there is no device to treat the remaining hydrofluoric acid in the system

Embodiment
[0032] Embodiment: a kind of anhydrous hydrofluoric acid unloading system, its structure is as figure 1 As shown, comprise the tanker parking area 24, be provided with at least two pipelines in the tanker parking area 24, one of them is the air inlet pipeline 26, and the end of the air inlet pipeline 26 is connected with the inert gas source 22, from the inert gas source 22 Looking in the direction of the tanker parking area 24, the inlet pipe 26 is also provided with an inert gas main pipe inlet valve 15, an inert gas regulating valve 3 and a pressure sensor 4 in sequence.
[0033] The other of the two pipelines is a liquid phase pipeline 27, and the liquid phase pipeline 27 is seen from one end near the tanker parking area 24 to the other end, and is equipped with a moisture on-line analyzer 9, a flow meter 10, and a liquid phase pipeline in sequence. Cut valve 11 and spherical tank feed quick cut valve 12. The feed quick-cut valve 12 of the spherical tank communicates with...

The invention relates to an anhydrous hydrofluoric acid unloading system. The anhydrous hydrofluoric acid unloading system comprises a tank car parking area. At least two pipelines are arranged in the tank car parking area, wherein one pipeline is a gas inlet pipeline and provided with a pressure sensor and a regulating valve. One end of the gas inlet pipeline is communicated with an indifferent gas source. The other pipeline is a liquid phase pipeline and communicated with a liquid phase pipeline quick switching-off valve, a spherical tank feed quick switching-off valve and a spherical tank sequentially. In the unloading process of a tank car, after flowing through the pressure sensor in the gas inlet pipeline, indifferent gas enters the tank car to transfer anhydrous hydrofluoric acid in a pressing mode into the spherical tank through the liquid phase pipeline quick switching-off valve and the spherical tank feed quick switching-off valve. Unloading is stopped when the pressure sensor monitors that the pressure is abnormal. The completely novel structure is designed for the anhydrous hydrofluoric acid unloading system so that leakage of the anhydrous hydrofluoric acid can be found out in advance, and harm to personnel and the environment due to chemical residues in the unloading process and other related problems can be effectively solved.
Description
technical field [0001] The invention relates to the technical field of hazardous chemical transportation, in particular to an anhydrous hydrofluoric acid unloading system. Background technique [0002] In industrial production, a large number of processes such as acid, alkali, and toxic media are used. At present, the strong corrosion and highly toxic chemicals used in most industrial fields are transported to the storage area by tank trucks, and then transported to the storage area through the transportation and unloading system. Chemicals are transported to storage tanks for use. [0003] Due to the high toxicity of anhydrous hydrofluoric acid, if it leaks accidentally, it will seriously affect the environment and cause harm to operators. Throughout the process of anhydrous hydrofluoric acid from production to delivery to users, because the daily use of acid is delivered by pumps, the equipment, pipelines and delivery methods are fixed, and each flange port has regular le...
