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
The present invention relates to a kind of trees emission gases and gather research device, specifically a kind of trees volatile organic chemistry material (VOCs) harvester in outdoor application.
Background technology
Volatile organic compounds (Volatile Organic Compounds, be called for short VOCs) is meant that boiling spread saturated vapor pressure under 50～260 ℃, room temperature surpasses the compound of 133.32Pa.This compounds is common to be present in the outdoor air, is playing the part of important role in the generation of Tropospheric ozone increase and other oxygenants, and it can also directly produce secondary pollutions such as organic gasoloid.The more important thing is that some compounds in the VOCs composition such as benzene, butadiene have potential carcinogenesis, so existence, the source of VOCs is subjected to many attention always in the research environment.At present, people are when discharging is studied to trees volatile organic chemistry material, need place organic glass box formula gas producing device and clamp the branch sampling at other fixed support or the iron tower set up of trees according to different research purposes, though such gas producing device can be monitored constantly to the branch of choosing, but operating process is loaded down with trivial details, workload is big, needs to drop into a large amount of man power and materials, is not easy to move.Therefore, people wish to have a kind of convenient disassembly, are convenient to move, cheap trees gas collecting device.
Summary of the invention
The purpose of this invention is to provide a kind of convenient disassembly, be convenient to move, cheap trees volatile organic chemistry material collecting device.
Technical solution of the present invention comprises: umbrella stull, transparent plastic bag, gas collecting pipe, draft tube, Hygrothermograph, illuminometer, adsorption tube and individual gas sampler.Wherein: transparent plastic bag covers on the umbrella stull.Gas collecting Guan Yiduan is positioned at transparent plastic bag and is fixed on the umbrella stull handle, and the other end is connected with the adsorption tube inlet end; The outlet side of adsorption tube is connected with the air inlet port of individual gas sampler; The draft tube of the port peace weighing apparatus pressure of giving vent to anger of individual gas sampler lays respectively in the transparent plastic bagging and is fixed on the umbrella stull handle.
The present invention has following advantage:
1, simple in structure, easy to operate.The umbrella frame of support can close up and launch, and is easy to carry;
2, transparent plastic bag shape and stent is big or small consistent, is convenient to calculate the volume of gathering gas, cheap;
3, the probe with humiture and illuminometer hangs in the umbrella stull body, can realize humiture and intensity of solar radiation and the monitoring of gas collecting synchronous dynamic in the harvester in the gas collecting process.
Description of drawings
Fig. 1 is the supporting structure synoptic diagram;
Fig. 2 is the transparent plastic bag planimetric map;
Fig. 3 is an one-piece construction synoptic diagram of the present invention.
The major part conventional letter: 1 is transparent plastic bag, and 2 is trees, and 3 is draft tube, and 4 is Hygrothermograph, and 5 is illuminometer, and 6 is individual gas sampler, and 7 is adsorption tube, and 8 is the gas collecting pipe, and 9 is support.
Embodiment
The specific embodiment of the present invention is described further as follows below in conjunction with accompanying drawing:
As shown in Figure 3, behind the branch of having chosen trees 2 to be measured, umbrella stull 9 is put into transparent plastic bag 1, launch umbrella stull 9 and cover on trees 2 branches, gas collecting pipe 8 one ends are positioned at transparent plastic bag 1 and are fixed on umbrella stull 9 handles, and the other end is connected with adsorption tube 7 inlet ends; The port of giving vent to anger of adsorption tube 7 is connected with the air inlet port of individual gas sampler 6; The draft tube 3 of the port peace weighing apparatus pressure of giving vent to anger of individual gas sampler 6 links to each other, and draft tube 3 other ends are positioned at transparent plastic bag 1 and are fixed on umbrella stull 9 handles; Hang up properly the probe (Hygrothermograph probe 4 ' and illuminometer probe 5 ') of Hygrothermograph 4 and illuminometer 5, be placed into draft tube 3 and gas collection tube 8 after, transparent plastic bag 1 is tightened on branch, writing time, begin to gather gas.
As shown in Figure 1, the umbrella frame of umbrella stull 9 can close up or launch, and is easy to carry;
As shown in Figure 2, transparent plastic bag 1 shape is consistent with the umbrella stull 9 of expansion, is convenient to calculate the volume of gathering gas.
