Description
Technical Field
The invention relates to a trace organic matter detection technology, in particular to an automatic trace organic matter detection gas circuit system for dioxin detection equipment.
Background
With the continuous development of garbage incineration treatment technology, the problem of smoke emission is also increasingly focused. Many enterprises are also developing devices to actively treat the problem of smoke emission, wherein the problems relate to the collection of smoke and the detection of harmful substances in the smoke. And the components of harmful substances in the flue gas are obtained, and the boiler is modified through analysis and verification, so that the emission of the harmful substances is reduced. The existing detection equipment is used for detecting the content of dioxin in the flue gas, and the function of detecting the dioxin in the flue gas is formed through the function cooperation of a plurality of instruments.
Because the content of dioxin in the flue gas is less and difficult to detect, the dioxin detection equipment needs multi-channel air inlet for realizing the functions of equipment such as detection, calibration, cleaning and the like. While the gas delivery is also achieved by the gas inlet system of the prior art devices, there are a number of inconveniences. Firstly, the flue gas and the standard gas are all independent pipelines, and the pipelines of the air pipe are complex due to the fact that more pipelines are carried out, so that the functions of the pipelines are difficult to distinguish. Secondly, the whole air inlet system pipeline is controlled by a single manual valve, inconvenience exists in ventilation detection and on-off and closing of an air valve, and the risk of air leakage at the joint of an air pipe and the valve is caused during operation, so that the whole detection result is influenced. In addition, the multiple gas lines are typically installed by drilling holes in the instrument cabinet, and the multiple lines pass through the equipment holes into the equipment to reconnect the instrument. Because the instrument is provided with a plurality of inner pipelines, the pipelines are overlong, the pipelines are easy to fold and flat in the arrangement process, so that the gas in the pipelines is blocked, and because a plurality of long-distance air pipes are arranged, the pipelines are easy to produce and pull, and air leakage is easy to generate.
The detection technology of the existing dioxin detection equipment mainly realizes detection under the synergistic effect of a laser and a mass spectrometer. Firstly, the flue gas enters a pre-concentration instrument through a pipeline, some impurities in the flue gas are removed, the concentration of the flue gas is improved, and then the flue gas enters a mass spectrum analyzer after passing through the pre-concentration instrument. The upper end of the mass spectrum analyzer is provided with a laser, and the energy emitted by the laser enables substances in the smoke to change the flight track, so that the substance components of the smoke entering the mass spectrum analyzer are judged. In this process, the flow of various gases inside the instrument is involved, and the pulse valve plays a role in controlling the flow of gases inside the instrument. A pulse valve is needed to be arranged on a pipeline between the pre-concentration instrument and the mass spectrum analyzer, and the main function of the pulse valve is to control the air inflow of the flue gas. The pulse valve is controlled to keep the smoke quantity entering the mass spectrometer consistent every time, so that the accuracy of a detection result is ensured, and the detection error is reduced. However, the existing pulse valve is a cavity with a single channel inside, and when the smoke enters the mass spectrometer according to the required quantity, the excessive smoke can be remained in the pulse valve. Because the smoke stays in the valve body for a long time, a large amount of substances in the smoke remain in the valve body after cooling, and the residual substances can influence the data of the next detection, so that the error of the detection data is increased. On the other hand, the data detection of the mass spectrometer can rely on the calibration of the standard gas, and the detection precision of the mass spectrometer can be improved after the calibration. Or the device operation condition can be detected by adding the standard gas, so as to determine whether the function of the instrument is normal. The existing pulse valve does not have the functions of marking gas and detecting equipment.
