Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas sampling, and in particular relates to a waste gas sampling device. Background Art

[0002] Waste gas is generated during some production processes. Sampling of waste gas can help companies monitor emissions from their production activities and take necessary control measures to reduce pollutant emissions. Waste gas sampling is also used for scientific research to understand the impact of different activities on air quality, which helps to formulate more effective environmental policies and technologies to reduce pollutant emissions. Waste gas may contain a range of pollutants, such as sulfur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), particulate matter, etc. By sampling and analyzing waste gas, the emission levels of these pollutants can be monitored and evaluated to ensure that their concentrations in the environment do not exceed legal standards, thereby protecting the health of natural ecosystems. Overall, waste gas sampling is an important tool for environmental protection and public health, helping to ensure the sustainable development of industry and other activities and reduce their negative impacts on the environment.

[0003] The existing waste gas sampling device currently lacks the function of dual detection. The lack of dual detection function may not be able to fully monitor the changes in waste gas before and after purification, which may easily lead to omissions or misjudgments. There is no data comparison before and after purification, and the actual effect of the purification equipment cannot be verified. It is difficult to determine whether the purification is effective and meets the standards. It is impossible to accurately monitor the composition and concentration of the waste gas after purification, and there are untreated harmful substances remaining, which increases the safety risks of operators and equipment.

[0031] refer to Figure 1 , Figure 2 and Figure 3A filter mechanism 6 is provided on the surface of the workbench 1, and the filter mechanism 6 includes a filter frame 601, a handle 602 and a filter screen 603.

[0033] Working principle:

[0034] When in use, the sampling mechanism 4 uses the sampling head 402 to collect exhaust gas samples from the exhaust gas source of interest, and the exhaust gas is introduced into the system through the air inlet pipe 403. The air pump 301 is turned on, and its exhaust function is used to make the exhaust gas be transported to the detection box 201 through the delivery pipe 302. The exhaust gas that has not been purified is preliminarily detected by the exhaust gas sensor 202 to monitor the exhaust gas composition and concentration and other information. The exhaust gas then passes through the purification mechanism 5 set on the surface of the workbench 1, in which the activated carbon 503 filters and adsorbs harmful substances in the exhaust gas. In this process, the partition net 502 is placed to support the activated carbon 503 to ensure fluidity. The exhaust gas passes through the filter net 603 in the filter mechanism 6 to remove solid After the body particles or droplets are detected, the purification effect sensor 203 further detects the composition and concentration of the purified exhaust gas to confirm whether the purification effect meets the emission standards, check the data feedback on the display 7, and observe the pressure information provided by the pressure gauge 8 to ensure that the equipment is running in a suitable state and the sampling accuracy. When the purification process is completed, the treated exhaust gas is discharged through the exhaust pipe 10, and the valve 9 is used to control the discharge flow and time. After collecting enough data, stop the air pump 301, close the valve 9, and save the relevant data for further analysis and processing; if necessary, replace or clean the filter 603 to ensure that the activated carbon 503 is still within the validity period for subsequent use.
