Description

Remote control sample collection device {REMOTE CONTROL SAMPLE COLLECTION APPARATUS}

The present invention relates to a remote control sample collection device, and more particularly, to remotely collect odors and VOCs generated from a distant odor emission source, continuously monitor the cause of odor, and intermittently collect a plurality of samples when odors occur. It relates to a remote control sample collection device for.

As the industry develops, the convenience of life increases, but environmental destruction by various pollutants generated in the industry is widely occurring.

In particular, odors and volatile organic compounds (VOCs) generated in industrial sites are more problematic because they can cause not only air pollution but also various diseases including skin diseases such as atopy in the human body.

Therefore, in the event of air pollution such as odor or VOCs occurring in industrial sites, samples must be collected immediately, and in the case of night time or when public officials cannot be dispatched to the site, remote management must be possible, and samples must be collected once. Even after that, when other civil complaints occur or when the sensor value indicates the severity of contamination, there is a need to immediately collect samples continuously or repeatedly.

Thus, multi-collecting techniques are being developed for collecting various pollutants.

The conventional collecting device as shown in FIG. 1 is a collection bag 12 installed in the housing 10 and the housing 10 to collect odor and VOCs samples, and a vacuum pump 14 for maintaining the interior of the housing 10 in a vacuum. ), an atmospheric opening/closing valve 16 connected to the collecting bag 12 to open/close the air inflow, and a pressure measuring device 18 for measuring the pressure inside the housing.

The sample collection device configured as described above is installed in an arbitrary place to collect samples in the atmosphere, and by opening the atmospheric opening/closing valve 16 while maintaining the inside of the housing 10 in a vacuum, odor and VOCs samples in the atmosphere are removed. It is allowed to flow into the collecting bag 12. Subsequently, the moment the sample is introduced, a wireless communication signal is sent to the manager so that the manager collects the collected collection bag 12.

The manager analyzes the collected samples to determine the degree of air pollution, and establishes countermeasures according to the results.

However, in the conventional sample collection device as described above, since the sample is collected only when the manager manually checks and opens the air on/off valve 16, it is possible to timely collect odors and VOCs, which are momentary and local sources of air pollution. There is a problem that will not exist.

In addition, while the odor may occur instantaneously and disappear sooner due to atmospheric conditions, etc., there are some areas where odors are frequently generated, and in some cases, pollution occurs continuously.

However, according to the above-described conventional collection device, it is not possible to cope with contamination in various types depending on the location or time. That is, if the pollution is regular and the amount is large, or if the pollution is temporarily excessive, the pollution cannot be solved because it is impossible to collect any more, and it is not possible to collect an accurate sample, so that the continued pollution cannot be properly coped with.

In particular, there is a problem in that the sample is diluted or the collecting bag is damaged due to foreign substances such as moisture or dust contained in odors and VOCs, which are sources of air pollution, making it difficult to accurately collect samples.
