Referring to fig. 1 to 3, the monitoring system for pollutant emission in an emergency according to the embodiment includes a sleeve 1, a sampling tube 3, a heating component 4 and a toxic and harmful substance sensor 9. Wherein a plurality of sampling ports 15 are provided on the sleeve 1 in the height direction thereof. The quantity of sampling pipe 3 is many, and sampling pipe 3 is located sleeve pipe 1 inside, and one of them sample mouth 15 is connected to the first end of every sampling pipe 3. The heating part 4 is positioned in the sleeve 1 and heats the sampling tube 3. The toxic and harmful substance sensor 9 is connected to the second end of the sampling tube 3.
This kind of pollutant discharge monitoring system in accident, owing to be provided with a plurality of sampling ports 15 along sleeve pipe 1 direction of height, and then can collect the pollutant in the region of different height to in leading-in the poisonous and harmful substance sensor 9 of lower part through different sampling pipe 3, acquire pollutant distribution law through the analysis of poisonous and harmful substance sensor 9, so that guide on-the-spot rescue and relevant personnel's evacuation work. Wherein, through set up heating part 4 in sampling pipe 3, and then can simulate the high temperature condition of pollutant in the scene of an accident or simulation experiment environment. Moreover, the heating part 4 can also avoid the generation of condensed water vapor on the side wall of the sampling pipe 3.
The pollutants mainly refer to pollutants carried in air. Further, whether or not the heating member 4 is turned on and the period of turning on may be determined according to the ambient temperature. When the ambient temperature is high, the heating element 4 needs to be turned on in order to simulate the temperature of the contaminants. When the ambient temperature is low, the heating element 4 may not be turned on.
It should be noted that, in addition to the sampling ports 15 distributed along the height direction, the cannula 1 may be provided with openings facing different directions at a specific height of the cannula 1. Under the condition, the pollutant emission monitoring system can monitor pollutants in different directions in an emergency.
Among them, the specific form of the toxic and harmful substance sensor 9 is not limited. For example, the toxic and harmful substance sensor 9 may be a sensor for detecting a concentration of carbon monoxide, a sensor for detecting a concentration of carbon dioxide, or a sensor for detecting a concentration of hydrogen cyanide, nitrogen oxide, or volatile organic compound. For another example, the toxic and harmful substance sensor 9 may be integrated with a plurality of toxic and harmful substance detection sensors, so that the concentrations of the plurality of toxic and harmful substances may be detected. There are sensors in the prior art that can detect six toxic and harmful substances.
In one embodiment, referring to fig. 2, the pollutant emission monitoring system in an emergency further comprises a particulate matter concentration sensor 8. Therefore, the pollutant emission monitoring system in the sudden accident can detect the concentration of the particulate matters besides the toxic and harmful substances.
For example, the particulate matter concentration sensor 8 may be a black carbon sensor, which may detect black carbon among contaminants. For another example, the particulate matter concentration sensor 8 may also be a PM2.5 (fine particulate matter) sensor or a PM10 sensor.
Wherein, the particulate matter concentration sensor 8 can be connected with the toxic and harmful substance sensor 9 in series, and also can be connected with the toxic and harmful substance sensor 9 in series and in parallel.

Of course, some occasions need not to detect the concentration of particulate matter, and only need detect poisonous and harmful substance, under this kind of circumstances, can adopt the filter screen to replace the particulate matter concentration sensor 8 that is located between sampling pipe 3 and poisonous and harmful substance sensor 9, prevents that the particulate matter from getting into poisonous and harmful substance sensor 9 and causing the damage to it. Also, the above-mentioned particulate matter concentration sensor 8 and the filter screen may be provided at the same time in a set of emergency pollutant discharge monitoring systems. And then can choose to install particulate matter concentration sensor 8 or filter screen to different occasions. In order to facilitate the replacement of the particulate matter concentration sensor 8 and the filter screen, the particulate matter concentration sensor 8 and the filter screen can be installed between the sampling pipe 3 and the toxic and harmful substance sensor 9 in a detachable mode.
Referring further to fig. 2, the monitoring system for pollutant emission in an emergency further includes a protective housing 5. Wherein, the protective housing 5 covers the outside of locating particulate matter concentration sensor 8 and poisonous and harmful substance sensor 9. By providing the protective case 5, the internal components can be protected from external impacts.

In addition, the controller 10 is connected with the particulate matter concentration sensor 8 and the toxic and harmful substance sensor 9, judges whether the concentration of the particulate matter or the toxic and harmful substance reaches a limit value, and can remind through the above mentioned display 7 when the concentration of the particulate matter or the toxic and harmful substance reaches the limit value. When the alarm is arranged, the alarm is connected with the controller 10 and sends out an alarm signal under the condition that the concentration of the particulate matters or the toxic and harmful substances reaches the limit value so as to prompt that the distribution of the pollutants at the corresponding height exceeds the limit value.
Of course, the controller not only judges whether the concentration of the particles or the toxic and harmful substances reaches the limit value, but also can control the opening and closing of each element, display setting, calibration concentration, alarm limit value setting, control of heating of the sampling pipe and the like.
In addition, a battery 12 may be provided in the protective case 5, and the above-mentioned toxic and harmful substance sensor 9, the particulate matter concentration sensor 8, the air pump 11, the controller 10, the alarm, and the like may be powered by the battery 12.

When the number of the particulate matter concentration sensors 8 is one, the number of the corresponding toxic or harmful substance sensors 9 may be set to one.
Secondly, the number of the particulate matter concentration sensors 8 is the same as that of the sampling pipes 3, and the controller 10 controls the opening of any on-off switch 6. Under this condition, because particulate matter concentration sensor 8's quantity is the same with sampling pipe 3 quantity, and then different particulate matter concentration sensor 8 can simultaneous working. From this, controller 10 can control a plurality of on-off switches 6 and open simultaneously, and then many particulate matter concentration sensor 8 can carry out particulate matter concentration detection simultaneously. Of course, the controller 10 may also control the plurality of on-off switches 6 to be turned on at different time periods.
In the second case, in the case where the number of the particulate matter concentration sensors 8 is the same as the number of the sampling tubes 3, the number of the toxic and harmful substance sensors 9 may be set to be the same as the number of the sampling tubes 3.
