Description
Technical Field
The invention relates to an atmospheric pollution monitoring device.
Background
The air pollution control is a pollutant emission control technology and a pollutant emission control policy which are adopted for treating air pollutants, and various special and harmful gas pollutants discharged by industry are easily solved by changing a production process or transferring and even closing a factory. The main atmospheric pollutants at present are smoke, carbon dioxide, nitrogen oxides and sulfides generated by burning fossil fuels, and carbon monoxide, carbon dioxide, hydrocarbons and nitrogen oxides emitted from automobile exhaust.
Air pollution monitors are also known as air quality monitors. The instrument for comprehensively detecting the air quality condition can detect the concentration of each pollutant in real time and send out an alarm prompt, and people can take related measures to reduce air pollution through the information given by the air pollution monitor, so that the aim of improving the environment is fulfilled. The method is widely applied to indoor air quality detection after home decoration. The air pollution detector can detect formaldehyde, PM2.5, TVOC and humiture in real time. Through its inside sensor, can accurate measurement pollutant concentration to calculate air quality index AQI, report to the police when the concentration exceeds standard. The air quality detector is based on the principle that signals of a front-end formaldehyde sensor, a PM2.5 sensor, a TVOC sensor and a temperature and humidity sensor are detected, weak signals of the sensors are amplified through an operational amplifier, noise interference is removed through a filter circuit, then the signals are acquired through AD (analog-to-digital) and are processed and calculated by a 32-bit high-precision CPU (central processing unit), and then the signals are converted into pollutant concentration values and displayed on a liquid crystal screen.
The pollutants in the atmosphere have the characteristics of time distribution, space distribution and diffusion migration. Its concentration is affected by wind direction, wind speed, turbulence, air temperature, air pressure, humidity and topography, and it is difficult to determine a fixed sampling location. The proper sampling position should be selected according to the actual conditions such as the measuring purpose, the physicochemical property of the pollutant, the current discharge state of the pollutant and the current meteorological conditions. Sampling should generally follow the following rules:
(l) When sampling outdoors, atmospheric samples without sedimentation must be collected in a flat zone around which there are no trees, tall buildings and other shelters, at a height of 50-180cm from the ground.
(2) When sampling indoors, a person's respiratory belt sample is to be collected 150cm away from the ground in the rest places of production and working personnel.
(3) The dustfall samples are typically collected at a distance of 500 cm above the ground or on the top of a building that is open at all sides, and not close to sources of pollution, construction sites and large nearby chimneys, to avoid the effects of wind sand and ground dust, etc.
(4) When a flue gas sample is collected, a sample with stable air flow and uniform smoke concentration is collected, and the collection position is selected in a vertical pipe section with a power supply, convenient operation and stable air flow, but not in front and back of a bend, a joint, a valve and an air blower. The existing monitoring device can not adapt to different sampling purposes, such as outdoor sampling, indoor sampling and the like, and the monitoring device for the atmospheric pollution needs to be adopted for different sampling purposes, so that the cost is high, and the detection equipment needs too much. In addition, although the ambient air monitoring instrument with the automatic rain and snow overload protection device in the prior art can continuously sample outdoors without the need of personnel on duty, the damage to the instrument caused by sudden rain and snow or water accumulation on the ambient air monitoring instrument is avoided, the normal work of the instrument is ensured, and the economic loss is recovered. However, after the rain and the rain pass, the ambient air monitor can continue to work after accumulated water on the sensor is dried, and the rain and the snow are accumulated on the top surface of the sensor for a long time, so that the detection data are incomplete.
Disclosure of Invention
