Problems solved by technology

At present, when people are studying the emission of volatile organic chemicals from trees, they need to set up fixed brackets or iron towers next to the trees according to different research purposes, and place a plexiglass box-type gas collection device to clamp the branches for sampling. Although such a gas collection device can The selected branches are constantly monitored, but the operation process is cumbersome, the workload is heavy, a lot of manpower and material resources are required, and it is not easy to move

Abstract

The invention relates to a tree emission gases study device, in particular to a tree volatile organic compounds collecting device which comprises an umbrella-shaped support and a transparent plastic bag. The transparent plastic bag is covered over the umbrella-shaped stand. Pipeline is communicated with a gas sampler at a place where the transparent plastic bag is fastened on a support. The probes of a hygrothermograph and a luxmeter are arranged in the transparent plastic bag. The device of the invention is easy to be arranged and dismounted, and has low cost, does no damage to the branches where gases are collected, and can realize the synchronous dynamic monitor of the temperature and humidity in the device and the solar radiation intensity and gas collecting in the gas collecting process.

Description

technical field [0001] The invention relates to a tree emission gas collection research device used outdoors, in particular to a tree volatile organic chemical (VOCs) collection device. Background technique [0002] Volatile Organic Compounds (Volatile Organic Compounds, referred to as VOCs) refer to compounds with a boiling point ranging from 50 to 260°C and a saturated vapor pressure exceeding 133.32Pa at room temperature. These compounds commonly exist in outdoor air and play an important role in the increase of tropospheric ozone and the generation of other oxidants, and they can also directly produce secondary pollutants such as organic aerosols. More importantly, some compounds in VOCs components, such as benzene and butadiene, have potential carcinogenic effects, so the research on the existence and source of VOCs in the environment has always been paid attention to by the public. At present, when people study the emission of volatile organic chemicals from trees, th...
