Description

Fuming acid sampler Technical Field The utility model belongs to the technical field of chemical sampling, and particularly relates to a fuming acid sampler. Background In chemical production, fuming acid is used as an important chemical raw material, the quality detection is of great importance, and the sampling link is the basis of the quality detection. At present, partial enterprises still use old-fashioned samplers to sample fuming acid, and the old-fashioned samplers are simple in structure and are generally made of carbon steel coiled round cans, and an acid discharging pipe is connected below the cans and is arranged at a fixed position, and acid is discharged after sampling. However, there are a number of drawbacks to such older samplers when used for sampling niacin. On the one hand, after the fuming acid is put into the barrel during sampling, sulfur trioxide in the fuming acid is easy to escape, acid mist is formed, operators can choke, the sight of the operators is blocked, the risk of being burnt by the acid is increased, and the acid mist can pollute the surrounding environment. On the other hand, the sampling tank is not provided with an acid return pipe, and acid is easy to overflow after being fully filled in the sampling process, so that people can be injured, and the environment can be further polluted.
