A kind of voc collection device and collection method

Abstract

The invention discloses a VOC collection device and a collection method, and relates to the technical field of gas collection. The invention comprises a storage box, the inner surface of the storage box is slidably connected with a collection box, the lower surface of the collection box is fixedly connected with a heating box, one surface of the storage box is threadedly connected with a fixing ring, and one surface of the storage box is fixedly connected with a drying box through the fixing ring. The first surface of the box is fixedly connected with the filter box through the fixing ring, the first surface of the filter box is threadedly connected with the first connecting cover, the upper surface of the first connecting cover is fixedly connected with the telescopic rod, one end of the telescopic rod is fixedly connected with the second connecting cover, the second connecting The surface of the cover is connected with a bellows. The present invention integrates a storage box, a collection box, a drying box, a number of collection tubes and a bellows through the connection structure, which reduces the volume of the device and can quickly collect the volatilized VOC in the sample in batches. , get rid of the valve and circuit control, and have the advantages of simple operation and portability.

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...
