Description
Technical field
The present invention relates to a kind of VOC blow devices, more particularly, to one kind for removing VOC multichannel purging dress in water sample
It sets.
Background technique
VOC is the english abbreviation of volatile organic compounds (volatile organic compounds), common meaning
On VOC be exactly to refer to volatile organic matter;But the definition on environment protection significance refers to active a kind of volatile organic matter, i.e., can
Generate that a kind of volatile organic matter of harm.VOC has tremendous influence to human health.When the VOC in room reaches certain dense
When spending, people can feel headache, Nausea and vomiting, out of strength etc. in the short time, will appear twitch, stupor when serious, and can hurt
The liver of people, kidney, brain and nervous system cause the serious consequences such as failure of memory.It is used during decoration design for residence
Coating be indoor VOC one of main source.So needing to carry out to the VOC content in the decorating and renovating materials such as coating tight
Lattice limitation.
The method of VOC in traditional processing water sample includes heating-gas explosion method, wherein influence testing result it is important because
One of element is exactly to analyze curve using the calibration of suitable standard error receipt, however the preparation of standard specimen pipe needs are accurate normal fluid
Injection be equipped with adsorbent thermal analytic pipe, purge in specific flow and under the defined time, to simulate practical sky as far as possible
Gas sampling process, but accurate gas flow and time control how are realized simultaneously without available instrument and device in the market
There is no suitable existing apparatus.And it usually needs handle multiple samples simultaneously, and when needing to guarantee the processing of multiple samples
Between, gas flow strict conformance has large error using flowmeter measuring flow, is not easy to select when gas flow is smaller
Suitable flowmeter;And current experimental rig, which is all made of, manually to be controlled, and it is equal that the adjustment of each flow, timing is manually operated
Manual operation is needed, and is not easy to guarantee that each flow is consistent, timing is consistent, can bring biggish human error;VOC is toxic
Substance, manual operation generate harm to the body of experimenter, not safe enough.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind for removing water sample
Middle VOC multichannel blow device.
The purpose of the present invention can be achieved through the following technical solutions:

Metal parts is that several rule gas circuit pipelines have been processed inside metal parts from being processed by fine aluminium material, every
The diameter in path is identical, and metal part surface is handled by surface lacquer, and guarantee works long hours can not in acid or alkali environment
Corroded;It is equipped with a switch in every gas circuit, for controlling the on-off of this pipeline, is only needed if there is sample needs to handle
Air pump is opened, and opens the switch button needed in certain gas circuit to be used, then the hose this gas circuit external connection
It is put into water sample, user can be consistent come the purge time for guaranteeing every pipeline with timing, guarantees uniformity for the treatment of.
Compared with prior art, the invention has the following advantages that
(1) timing is convenient, accurately guarantees that the aeration time of each sample is consistent, reduces experimental error, facilitates experimenter
Operation;Multiple branches are provided, multiple samples can be handled simultaneously, improve conventional efficient;
(2) since the resistance of each branch is consistent, guarantee that the air mass flow of each branch is exactly the same, do not need to survey respectively
Measure the flow of each branch, it is only necessary to measure total flow, then can be obtained accurately with total flow divided by the quantity for opening branch
Branch gas flow, be further reduced experimental error, improve conventional efficient;
(3) experiment condition lesser for gas flow, by increasing the branch number opened, so that total flow is in flow
Within the scope of the optimum measurement of table, the measurement accuracy of flow is further ensured;
(4) branch switch of each branch and the switch of body passageways can be using the motor-driven valves that can remotely control
Door, substantially increases automatization level, avoids operator's contact test sample, improve the safety of experiment;
(5) gas distribution mechanism is an integral structure, and the good airproof performance of structure is not easy gas leakage;
(6) apparatus structure is simple and reliable, and cost performance is high.
