Description

Malodorous gas sampling device Technical Field The utility model relates to the technical field of gas sampling, in particular to a malodorous gas sampling device. Background The industrial malodorous gas is a byproduct in the production links of chemical industry, coating, pharmacy and the like, contains the strong odor substances such as mercaptan, phenols, aldehydes and the like, escapes at nodes such as raw material reaction, product distillation, wastewater treatment and the like, has the characteristics of fast diffusion and low odor threshold value, is easy to cause disputes of factories and is an important point of environmental protection supervision. Malodorous gas components are complex and possibly contain various substances such as hydrogen sulfide, ammonia gas and volatile organic compounds, therefore, a gas sample needs to be collected through a sampling device, and a professional analysis instrument is reused, so that the types and the concentrations of various components can be accurately measured, but the traditional sampling device is generally inconvenient to detach the gas pipe, the sampling device needs to be comprehensively checked and prepared before each sampling task starts, and if the gas pipe is inconvenient to detach, a great deal of time is consumed in detachment and installation when the gas pipes with different lengths, materials or specifications need to be replaced to adapt to different sampling scenes. Disclosure of utility model The utility model aims to provide a malodorous gas sampling device for solving the problems in the background technology. In order to achieve the purpose, the utility model provides the following technical scheme that the malodorous gas sampling device comprises a sampling cylinder and further comprises: The cylinder cover is arranged at one end of the sampling cylinder, and one side of the cylinder cover is provided with a gas pipe; The disassembly assembly is positioned at one end of the gas pipe and comprises a connecting pipe communicated with one end of the gas pipe, one end of the connecting pipe is communicated with a fixed pipe, and the inner wall of the fixed pipe is communicated with a mounting pipe; the clamping piece is arranged on the outer side of the installation tube, and a reset piece for resetting the clamping piece is arranged on the outer side of the fixing tube.
