Abstract

The invention discloses a VOC collection device and collection method, and relates to the technical field of gas collection. The VOC collection device comprises a storage box, a collection box is slidably connected to the inner surface of the storage box, a heating box is fixedly connected to the lower surface of the collection box, one surface of the storage box is in threaded connection with a fixing ring, one surface of the storage box is fixedly connected with a drying box through a fixing ring, one surface of the drying box is fixedly connected with a filtering box through a fixing ring,one surface of the filtering box is in threaded connection with a first connecting cover, the upper surface of the first connecting cover is fixedly connected with a telescopic rod, one end of the telescopic rod is fixedly connected with a second connecting cover, and one surface of the second connecting cover communicates with an air box. According to the VOC collection device, the communicationstructure of the storage box, the collecting box, the drying box, a plurality of connecting pipes and the air box is adopted for integration, so that the size of the device is reduced, volatile VOC ina sample can be rapidly collected in batches, valve and circuit control is eliminated, and the advantages of being simple in operation, and convenient to carry are achieved.

Description

technical field [0001] The invention relates to the technical field of gas collection, in particular to a VOC collection device and a collection method. Background technique [0002] VOC refers to volatile organic compounds. In the general sense, VOC refers to volatile organic compounds; but the definition in the sense of environmental protection refers to a class of active volatile organic compounds, that is, under normal pressure conditions, the melting point is lower than room temperature and the boiling point is between 50 and 260 ° C. Organic compounds, and such organic compounds will cause certain harm to the human body. [0003] Collecting samples for VOC detection can prevent the air with volatile VOC from harming the human body. However, the current VOC collection equipment is too bulky and has poor maneuverability, which is not conducive to the development of outdoor collection work. The cost of learning, and the existing VOC acquisition equipment is collected by...
