Abstract

The invention provides a sampling device which comprises an impurity removal part and a sampling part, wherein the impurity removal part is communicated with a sampling port of a sampling apparatus and receives detection gas in the sampling apparatus and removes impurities in the detection gas; an impurity discharge port is formed at the impurity removal part; and the sampling part is communicated with the impurity removal part and used for discharging the detection gas after impurity removal. According to the invention, through the impurity removal part, at the time when the detection gas conveyed by the sampling apparatus is received, the impurity removal part performs impurity removal treatment on the detection gas, the impurities in the detection gas can be discharged in time, and thus the detection gas can meet the requirements of the detection equipment, the contamination of the detection gas caused by impurities is avoided, the integrity and purity of all components in the detection gas are effectively guaranteed, the treatment effect of the detection gas is improved, and the accuracy of the detection result of the detection equipment is enhanced.

Description

technical field [0001] The invention relates to the technical field of gas sampling, in particular to a sampling device. Background technique [0002] At present, for most of the equipment, it is usually necessary to extract a part of the gas in the equipment, and detect the components in the extracted gas to perform related operations on the equipment, such as adjusting the pressure, temperature or working time in the equipment. For example, in the field of coal chemical industry, in the process of coal gasification, it is necessary to extract a part of the gas through the sampling device, and the detection instrument detects the extracted gas. However, the gas extracted by the existing sampling device often carries impurities such as moisture and coal powder, which will lead to inaccurate gas detection results and also pollute the detection equipment. Therefore, it is necessary to pretreat the impurities in the gas to remove the impurities in the gas. [0003] Usually, t...
