Embodiment approach

[0037]Specific embodiments: when performing gas sampling, first fill a certain amount of pure glass wool in the filling section 73, then assemble the connecting section 74 and the exhaust pipe 3, the filling section 73 and the connecting section 74, the filling section 73 and the sampling pipe 1, Air extraction pipe 3 and air bag 5; after the assembly is completed, the air tightness of the pollution source odor sampling system needs to be checked, and the air pump 6 is used to inflate the vacuum layer 41 to squeeze out the gas in the air bag 5, and then the air inlet 11 Block up, utilize air suction pump 6 to carry out vacuumizing process to vacuum layer 41, observe whether air bag 5 expands simultaneously, if the situation of expansion occurs in air bag 5, then this pollution source malodorous sampling system leaks, then further confirms the leak position, if If the air bag 5 does not inflate, the odor sampling system of this pollution source will not leak, and the odor gas sa...

Abstract

The invention relates to a pollution source stink sampling system. The system comprises a sampling tube, an exhaust tube and an annular connecting part of a hollow structure, an air inlet is formed inone end of the sampling tube, the annular connecting part is arranged at the air inlet in the sampling tube, an external thread is formed in the end, close to the air inlet, of the annular connectingpart, and matched with an internal thread of the sampling tube, and an internal thread is formed in the other end of the annular connecting part and matched with an external thread of the exhaust tube; the end, away from the air inlet, of the exhaust tube extends out of the sampling tube, an air bag is connected to the end, and the air bag is arranged in a vacuum sampling box; the exhaust pipe isa polytetrafluoroethylene pipe; the system comprises a temperature control box which is arranged at the end, away from the air inlet, of the sampling tube, and the temperature control box is electrically connected with a heating device in the sampling tube. The system has the advantages that the structure is simple and reasonable, the integration level is high, equipment is small and convenient,and use is convenient.

Description

technical field [0001] The invention relates to the field of environmental monitoring sampling equipment, in particular to a pollution source odor sampling system. Background technique [0002] Malodor is a general term for various odors (odors). When the peculiar smell in the environment reaches a certain level, it will make people feel unpleasant, and even have psychological impact and physiological harm on people, which is called stench pollution. Due to the serious harm of stench to the human respiratory system, nervous system and digestive system, it has become the seventh largest public hazard after the atmosphere, water quality, soil, noise, vibration and ground subsidence. With the rapid acceleration of my country's industrialization process and the improvement of people's awareness of surrounding environmental protection, odor pollution has become a hot spot and focus of environmental complaints. [0003] At present, the method of vacuum box inflatable bag is used...
