Description

Technical Field

[0001] The present invention relates to the technical field of environmental governance, and in particular to an environmental pollution monitoring instrument. Background Art

[0002] The environmental pollution monitoring instrument is an instrument developed by us in response to the current severe environmental situation. It monitors a total of 12 parameters, including the amount of dust in the air, harmful gas parameters and room temperature gases, as well as air temperature and humidity, wind speed, wind direction, atmospheric pressure and rainfall.

[0003] In particular, near some chemical plants, due to the substandard quality of the exhaust gas, the atmosphere and rainfall will be rich in a large number of harmful gases such as CO, SO2 or NO2 and heavy metal ions. Therefore, it is necessary to monitor the atmosphere and rainwater separately, which increases the monitoring cost. At the same time, during the rainfall process, some harmful gases will dissolve into the rainwater, thereby reducing the content of harmful gases in the atmosphere. At this time, if the atmosphere and rainwater are monitored separately, it will affect the monitoring effect of the atmosphere. When monitoring heavy metal ions in rainwater, due to the low average content of heavy metals in rainwater, direct monitoring using traditional detection instruments will result in greater randomness, resulting in larger monitoring errors. At the same time, due to the heavy metal emissions from chemical plants, when the rainfall is heavy, the heavy metal content in the later rainwater is lower than before. If the instrument is used directly for monitoring, the monitoring results will be inaccurate.

[0004] Therefore, the present application provides an environmental pollution monitoring instrument to meet the needs. Summary of the invention

At this time, the atmospheric pollution environment monitor 244 contacts the air and detects it; When it rains, rainwater enters the water storage box 270 through the filter plate 4 272, and then enters the X-shaped tube 210 through the filter plate 250. The excess rainwater is discharged from the discharge groove 271. The rainwater that enters the X-shaped tube 210 flows into the wind measurement shell 240, and then is discharged into the X-shaped tube 210 again through the discharge pipe 230, and finally discharged into the funnel 112 from the bottom of the X-shaped tube 210. The rainwater in the funnel 112 is discharged into the analysis tube 111 from the bottom of the control funnel 120. As the volume of rainwater in the analysis tube 111 increases, the float 123 can be driven to slide upward on the siphon 121, so that the float 123 The output port at the bottom of the control funnel 120 is blocked. At this time, the rainwater in the funnel 112 cannot fall. As the rainwater in the funnel 112 increases, when the liquid level of the rainwater is flush with the discharge pipe 113, the excess rainwater in the funnel 112 can be discharged to the outside of the analysis cylinder 111 through the discharge pipe 113. At this time, the loading cylinder 116 is placed in the cartridge 114 and connected to the capillary dropper 115. The inner diameter of the capillary dropper 115 is 0.05-0.07 mm. The mercury in the loading cylinder 116 passes through the capillary dropper 115 and forms mercury drops at its lower end. When the diameter of the mercury drop exceeds the inner diameter of the capillary dropper 115, due to gravity, the mercury drops are discharged to the outside of the analysis cylinder 111. At the same time, 220V AC is sent into the analysis cylinder 111 through a high resistor of 1 megohm. At this time, there are two electrodes in the analysis cylinder 111, namely, a microelectrode with a smaller area (i.e., the mercury electrode dripped by the capillary dropper 115) and an electrode 117 with a larger area. Under a constant current, the measured ions of the rainwater in the analysis cylinder 111 are electrolytically deposited, so that the mercury enriched on the electrode 117 forms amalgam. After the enrichment is completed, after standing for 30s or 60s, a reverse voltage is applied to the electrode 117 to re-oxidize the metal in the amalgam into ions and return to the solution, generating an oxidation current and Record the voltage and current curve, the curve is peak-shaped, the peak current is proportional to the concentration of the measured ion in the solution, which can be used as a basis for quantitative analysis, and the peak potential can be used as a basis for qualitative analysis, so as to monitor the heavy metal content in the analysis cylinder 111, and use the atmospheric pollution environment monitor 244 to monitor the air during rainfall. At the same time, drive the micro pump 122 every 60 minutes to fill the siphon 121 with rainwater. Based on the siphon effect, the rainwater in the analysis cylinder 111 can be completely discharged, so that the rainwater in the funnel 112 is refilled into the analysis cylinder 111, so as to perform secondary monitoring and improve the monitoring accuracy; During the rainfall process, if the atmosphere is monitored, the solenoid valve 211 can be opened to allow rainwater to enter the wind measuring shell 240 through the access pipe 241, and the negative suction fan 243 in the wind measuring shell 240 can be cleaned to remove dust and other debris on its surface. The cleaned rainwater enters the funnel 112 through the discharge pipe 230. After the cleaning is completed, the solenoid valve 211 is closed and the negative suction fan 243 is driven to dry the wind measuring shell 240. After the monitoring of the rainwater in the analysis cylinder 111 is completed, the steering gear 144 can be driven to drive the connecting rod 145 to rotate, thereby driving the connecting rod 2 146 to rotate, so that the bridge-type connecting plate 143 is translated, and the flip blade 142 is deflected, so that the rainwater in the analysis cylinder 111 is discharged through the drying cylinder 131. After the rainfall is over, the motor 135 is driven to drive the gear set 134 to rotate, thereby driving the negative suction fan 132 to work, and the drying cylinder 131 and the analysis cylinder 111 are dried.
