HF sampling device for alkylation process

The utility model discloses an alkylation process HF (hydrogen fluoride) sampling device which comprises a sampling acid circulating pipeline, an alkylation reactor, a sampling barrel, a plurality of reactor acid valves and a reactor discharge end are arranged on the sampling acid circulating pipeline, one end of the alkylation reactor is connected to one end of the sampling barrel, and the other end of the sampling barrel is connected to the reactor discharge end. The other end of the sampling barrel is connected to the discharge end of the reactor and the other end of the alkylation reactor, an alkylation reactor acid sampling pipe group is constructed through the design of a pipeline and a valve, closed sampling of hydrofluoric acid is realized, the environmental risk is reduced, the body health of staff is ensured, and the working efficiency is improved. When the sampler is used for hydrofluoric acid sampling, basically no HF is discharged, considerable economic benefits and environmental benefits can be
