Description
Technical Field
The utility model belongs to the technical field of the environmental protection monitoring, a sampling device that is used for miniature station of factory boundary monitoring is related to.
Background
The utility model relates to a factory boundary monitoring micro station, which integrates PM2.5, PM10 and NO2、O3And a plurality of environmental parameters such as TVOC, humiture and the like. Where TVOC refers to volatile organic compounds, ASTM D3960-98 of the United states defines it as any organic compound that can participate in atmospheric photochemical reactions, which are widely used. Indoor useWhen the TVOC concentration is too high, poisoning is easily caused, inappetence, dizziness, influence on the nervous system and the like appear. TVOC can also destroy atmospheric environment, cause atmospheric pollution, and influence air quality.
At present, factory monitoring micro stations in the market can only alarm TVOC measurement; some devices are very heavy although various parameters are integrated, and because a sampling device is unreasonable, all the parameters interfere with each other, and the measurement result is inaccurate.
Disclosure of Invention
The utility model aims at the above-mentioned technical problem, a sampling device for factory boundary monitoring micro-station is provided, in limited spatial structure, link together each environmental parameter's sensor rationally through the gas circuit to carry out rain-proof, prevent wind, waterproof design to the collection part, make it guarantee measuring result's accuracy. The technical scheme of the utility model as follows.
The utility model provides a sampling device for factory monitoring micro-station, its characterized in that includes sampling probe and airtight waterproof box to and be located filter, environmental parameter sensor and the aspiration pump of box, the sampling probe is protected with rain-proof cap, and the sampling probe passes through the sampling pole to be connected with the filter, and filter, environmental parameter sensor and aspiration pump loop through gas piping connection.
Further, the environmental parameter sensor is a TVOC sensor and an NO sensor in turn2Sensor, O3A sensor and an odor sensor.
The utility model discloses each parameter sensor rationally arranges, and the gas circuit evenly passes, and the air current is stable, and measuring result is stable accurate. The sampling device has no leakage under outdoor conditions, and the maintenance and the investigation are simple and easy to operate.
Drawings
FIG. 1 is a schematic diagram of a sampling device for a plant monitoring micro-station.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, the sampling device for the plant monitoring micro station comprises a sampling probe, a closed waterproof box body, a filter, an environmental parameter sensor and an air pump, wherein the filter, the environmental parameter sensor and the air pump are positioned in the box body, and the sampling probe is protected by a rain-proof cap. The gas sample collected by the sampling probe enters the box body through the sampling rod and is connected with the sensors through the hoses, the sensors are arranged at different positions according to the characteristics of respective measurement objects, and then the sensors are connected through the hoses and finally discharged from the lower part of the box body after passing through the air suction pump.
The rain-proof cap design through sampling probe guarantees that the air current of admitting air does not contain the water droplet, tentatively makes the vapor condensation through the condensation of sampling pole length distance. And absorbed by the filter. The connection sequence of the sensors is TVOC-NO2-O3Odor, avoiding mutual interference of the measurement data.
