The invention relates to the technical field of environmental monitoring equipment, and discloses a gas trap for environmental monitoring and chemical element analysis, the gas trap comprises a base, the center of the upper surface of the base is fixedly connected with a fixed cylinder, an adjusting rod is inserted in the fixed cylinder, the top of the adjusting rod is fixedly connected with a connecting seat, and the connecting seat is fixedly connected with a gas inlet pipe. A groove is formed in the upper surface of the connecting base, and the inner side wall of the groove is rotationally connected with a transverse rod through a damping rotating shaft. According to the gas trap for environmental monitoring and chemical element analysis, through cooperative arrangement of the collecting box, the collecting hole, the collecting hopper, the collecting pipe, the connecting pipe, the collecting main pipe, the negative pressure pump, the output pipe and the collecting bottle, gas at a monitoring point is trapped; the height of gas captured by the collecting box can be adjusted through an adjusting rod, a threaded fixing hole and a fixing bolt, and through the arrangement of a filter plate, filtering is carried out during gas capturing, so that the accuracy of environmental monitoring chemical element analysis is greatly improved.
Description
technical field [0001] The invention relates to the technical field of environmental monitoring equipment, in particular to a gas trap for analyzing chemical elements in environmental monitoring. Background technique [0002] Environmental monitoring refers to the determination of environmental quality (or pollution degree) and its changing trend through the determination of representative values of factors affecting environmental quality. Since the development of my country's economy will inevitably be accompanied by environmental pollution, scientific research is required to reduce the degree of environmental pollution. Only when personnel analyze the chemical composition in the air can they find ways to control environmental pollution. Therefore, the staff need to sample the air at the testing site, which requires the use of gas traps to facilitate the staff to sample the air. [0003] The gas trap is an instrument used for gas collection; the environmental detection is ...
