When the device is used, the first electric push rod 20 is controlled and started by the device, so that a sealing plate part of the sealing cover plate 19 can enter the sampling tank 9, meanwhile, the second electric push rod 22 is controlled and started by the device, the second electric push rod 22 is in a limit extension state, at the moment, the detection values of the air pressure sensor 26 and the air speed sensor 28 are zero, then the device is moved to a designated sampling place, the mixed flow fan 4 is started, the electric flow control valve 6 is opened, smoke can be rapidly extracted into the smoke suction cover 5 through the mixed flow fan 4, then the smoke entering the smoke suction cover 5 can be rapidly enter the smoke collecting and equalizing control box 13 through the first conveying communicating pipe 7, after the smoke collecting and equalizing control box 13 collects the smoke with designated time, at the moment, the first conveying communicating pipe 7 and the smoke suction cover 5 are closed through the electric flow control valve 6, the mixed flow fan 4 is stopped, at the moment, the motor 15 is driven by the motor 15 to rotate the rotating impeller 14 at a constant speed in the designated sampling place, at the moment, the smoke collecting and equalizing control box 13 can be rapidly extracted into the smoke suction cover plate 13 through the mixed flow fan 4, then the smoke entering the sealing cover plate 19 through the first conveying communicating pipe 7 and the second communicating pipe 13, the smoke collecting and equalizing control box 19 can be simultaneously, the smoke collecting and the smoke at the designated time is completely through the sealing cover plate 9, the sealing cover plate 19 is simultaneously, the sealing plate 19 is slid and the sealing cover plate 19 is simultaneously, and the sealing plate 19 is simultaneously is moved into the sealing cover plate 9 through the sealing plate 9, and the sealing plate is simultaneously, and the sealing plate 19 is simultaneously, and the sealing plate is simultaneously, the sealing plate is sealed.
When the flue gas passes through the filter plate of the sealing cover plate 19 and enters the sampling tank 9, flying flocks and other sundries in the flue gas are filtered through the filter plate of the sealing cover plate 19, so that the detection result is more accurate when the flue gas entering the sampling tank 9 is subjected to subsequent detection, and the use effect of equipment is improved.
In the long-term use process of the device, the filter plate part of the sealing cover plate 19 corresponding to each sampling tank 9 is blocked, and the blocking condition of the filter plate part of each sealing cover plate 19 is inconsistent, so that when the sampling tank 9 collects smoke, the smoke concentration in the sampling tank 9 corresponding to the sealing cover plate 19 with light blocking condition is easy to cause, and the smoke concentration in the sampling tank 9 corresponding to the sealing cover plate 19 in blocking condition is small, in order to avoid the blocking condition, when the smoke passes through the filter plate of the sealing cover plate 19 and enters the sampling tank 9, if the blocking condition of the filter plate of the sealing cover plate 19 corresponding to the sampling tank 9 is lighter than that of the filter plates of the other five sealing cover plates 19, smoke entering the sampling tank 9 is increased, further the detection value of the air pressure sensor 26 in the sampling tank 9 is increased, and if the air speed sensor 28 can detect the air speed value at the moment, the device controls the first electric push rod 20 to operate, so that the sealing cover plate 19 is controlled to move, and the sealing plate part of the sealing cover plate 19 is made to move to the inside the sampling tank 9, so that the air quantity of the smoke entering the sampling tank 9 is reduced, and the air quantity of the sampling tank 9 is prevented from being smaller than that the air quantity entering the sampling tank 9.
If the blocking condition of the filter plate of the sealing cover plate 19 corresponding to the sampling tank 9 is lighter than that of the filter plates of the other five sealing cover plates 19, the amount of smoke entering the sampling tank 9 is increased, so that the detection value of the air pressure sensor 26 in the sampling tank 9 is increased, if the detection value of the air speed sensor 28 is zero at this time, the amount of smoke in the sampling tank 9 reaches the volume required to be collected, and the second electric push rod 22 stops working, the device controls the first electric push rod 20 in the other sampling tanks 9 to operate, so that the sealing cover plate 19 is controlled to move, the filter plate part of the sealing cover plate 19 is moved to the inside of the sampling tank 9 more, the size of the air inlet of the other sampling tanks 9 is increased, so that more smoke enters the other sampling tanks 9, and in the process, the air inflow in the other sampling tanks 9 is increased, so that the suction in the sampling tank 9 is formed, the filter plate part of the sealing cover plate 19 of the sampling tank 9 is slightly vibrated, and flying flocculation and sundries on the filter plate are correspondingly cleaned.
If the blocking condition of the filter plate of the sealing cover plate 19 corresponding to the sampling tank 9 is heavier than that of the filter plates of the other five sealing cover plates 19, the amount of smoke entering the sampling tank 9 is reduced, so that the detection value of the air pressure sensor 26 in the sampling tank 9 is reduced, at the moment, the equipment controls the first electric push rod 20 corresponding to the sampling tank 9 to start, thereby controlling the sealing cover plate 19 to move, enabling the filter plate part of the sealing cover plate 19 to move more into the sampling tank 9, increasing the size of the air inlet of the sampling tank 9, enabling more smoke to enter the sampling tank 9, and ensuring the same air inflow of the sampling tank 9 and other sampling tanks 9.
If the blocking condition of the filter plate of the sealing cover plate 19 corresponding to the sampling tank 9 is heavier than that of the filter plates of the other five sealing cover plates 19, the amount of smoke entering the sampling tank 9 is reduced, so that the detection value of the air pressure sensor 26 in the sampling tank 9 is reduced, at the moment, the equipment controls the first electric push rod 20 in the sampling tank 9 to operate, thereby controlling the sealing cover plate 19 to move, enabling the sealing plate part of the sealing cover plate 19 to move more into the sampling tank 9, reducing the size of the air inlets of other sampling tanks 9, enabling more smoke to enter the sampling tank 9, and in the process, because the air inflow in other sampling tanks 9 is reduced, blowing and pressing in the sampling tank 9 are formed, and further the filter plate part of the sealing cover plate 19 of the sampling tank 9 is slightly vibrated, so that flying flocks and sundries on the filter plate are correspondingly cleaned.
According to the invention, the air pressure sensor 26, the air speed sensor 28, the first electric push rod 20 and the second electric push rod 22 are arranged, the air flow collected in the sampling tank 9 is indirectly detected by the aid of the air pressure sensor 26, whether the sampling tank 9 is completely collected is indirectly judged by the air speed sensor 28, meanwhile, the first electric push rod 20 and the second electric push rod 22 are matched to ensure that the same flue gas collection speed and the same flue gas collection amount of each sampling tank 9 are maintained, flying flocks and other sundries in the flue gas are filtered by the sealing plate and the filter plate of the sealing cover plate 19, the size of the air inlet of the sampling tank 9 is controlled, and the convenience of equipment use and the use effect are improved.
