Sampling device and chemical engineering system

Abstract

The invention relates to the technical field of chemical sample sampling, and discloses a sampling device and a chemical system.The sampling device comprises a first multi-way valve (11) and a second multi-way valve (18) which are connected to sample storage equipment through a material passing pipeline (9) and a backflow pipeline (16) respectively, a sampler connected between the first multi-way valve (11) and the second multi-way valve (18), and a pressure reducing pipeline (14); the first multi-way valve (11) is connected with a nitrogen pipeline (12) used for filling nitrogen, and the first multi-way valve (11) and the second multi-way valve (18) can be controlled to enable the backflow pipeline (16) to be selectively communicated with one of the nitrogen pipeline (12) and the material passing pipeline (9) through the sampler. The sampling device provided by the invention is convenient for workers to operate, and can effectively control the collection of samples. In other words, the sample can be rapidly collected, the collector can be rapidly replaced, and meanwhile the remaining sample can be reasonably treated.

Description

technical field [0001] The invention relates to the technical field of chemical sample sampling, in particular to a sampling device and a chemical system. Background technique [0002] There are many liquid samples in the coal chemical and petrochemical industries, and the collection of liquid samples is also a very important part of the analysis. The requirements for sampling are not only representative, but also safety, environmental protection and other factors. How to quickly take representative samples safely and environmentally friendly is a long-standing problem. [0003] At present, in the process of sampling volatile and flammable samples, directly sampling the samples will cause the samples to splash, so that the samples are volatile, flammable and other emergencies, which pose safety and environmental risks. Existing sampling devices cannot guarantee the collection of samples under airtight conditions, and the reasonable treatment of the remaining samples after c...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sampling device and a chemical system in order to overcome the problems existing in the prior art that samples cannot be collected under airtight conditions, and that the remaining samples cannot be properly processed after collection. The device is not only convenient for workers to operate, but also can effectively control the collection of samples
