Problems solved by technology

The existing sampling modules usually have the following problems during use: 1) The samples taken are not representative. When sampling, the existing sampling modules usually randomly take samples from the gas or liquid delivery pipeline and submit them for inspection. However, due to the poor fluidity of the medium close to the pipe wall in the pipeline, it is difficult to ensure that the sample taken is representative; 2) It is easy to cause leakage during sampling, which pollutes the environment and damages the health of the sampling staff

Abstract

The invention discloses a single-point sampling detection system with micro pressure, which belongs to the technical filed of sampling device. The detection system is characterized in that: the inletend of a conveying tube (10) is communicated with the outlet end of the conveying tube, and the outlet end of the conveying tube (10) is connected in series with a color-comparison tube (7) and is communicated with an adsorption tank (9). The inlet end of a return tube (26) is communicated with the outlet end of the conveying tube (10), and the outlet end of the return tube (26) is communicated with an inlet tube. A sampling check valve (22) is provided between the conveying tube (10) and the inlet tube. A return check valve (23) is provided on the return tube (26). A sampling valve (5) is provided between the conveying tube (10) and the color-comparison tube (7). The inlet tube is provided with an inlet valve (1). A pressure boosting device is provided between the conveying tube (10) andthe inlet tube. According to the single-point sampling detection system with the micro pressure, samples taken by the single-point sampling detection system with the micro pressure are representativeand easy to operate during sampling; and medium leakage during sampling and pollution to the environment are avoided, thereby having a wide application range.

Description

technical field [0001] A micro-pressure single-point sampling detection system belongs to the technical field of sampling equipment. Background technique [0002] In chemical production, it is necessary to sample and test the produced gas or liquid to ensure that the produced product meets the requirements, or to detect whether the content of harmful components in the produced gas exceeds the standard to determine whether the gas can be directly discharged into the atmosphere without Will pollute the environment. The existing sampling modules usually have the following problems during use: 1) The samples taken are not representative. When sampling, the existing sampling modules usually randomly take samples from the gas or liquid delivery pipeline and submit them for inspection. However, due to the poor fluidity of the medium close to the pipe wall in the pipeline, it is difficult to ensure that the sample taken is representative; 2) It is easy to cause leakage during sampl...
