Description

Technical Field

[0001] The utility model relates to the technical field of flue gas monitoring devices, and particularly relates to a flue gas sampling probe capable of automatically removing dust. Background Technique

[0002] A flue gas monitoring device refers to a device that continuously monitors the concentration and total emission of gaseous pollutants and particulate matters emitted from atmospheric pollution sources and transmits information to the competent department in real time. It is composed of a gaseous pollutant monitoring subsystem, a particulate matter monitoring subsystem, a flue gas parameter monitoring subsystem, and a data acquisition, processing, and communication subsystem. It includes a flue gas sampling probe for sucking the target gas into the monitoring system. When monitoring the flue gas discharged from a chimney, a through hole is opened on the side wall of the chimney, and the flue gas sampling probe extends into the chimney through the through hole to collect the flue gas. The connection between the sampling probe and the chimney is sealed with cement mortar. After the flue gas enters the flue gas sampling probe, some dust and impurities will be left inside, and manual cleaning is required. Since the chimney is located at a high place, manual cleaning is very inconvenient. Content of the Utility Model

[0003] The purpose of this application is to provide a flue gas sampling probe capable of automatically removing dust to solve the problems mentioned in the above background technique.

[0004] To achieve the above purpose, this application provides the following technical solution: A flue gas sampling probe capable of automatically removing dust, including a flue gas probe housing, one end of the flue gas probe housing is fixedly installed with an end cover, a partition is fixedly installed inside the flue gas probe housing, a U-shaped flue gas channel is enclosed between the partition and the flue gas probe housing, a flue gas detection sensor is fixedly installed at the inner end of the end cover, and the flue gas detection sensor is located at the end of the U-shaped flue gas channel. The inside of the partition is cavity-shaped, and both opposite sides of the partition are communicated with a first air blowing port. There are several first air blowing ports and they are arranged in an array. One end of the partition is communicated with several second air blowing ports, and the second air blowing ports face the flue gas detection sensor. The cavity of the partition is communicated with a high-pressure air pipe. One end of the flue gas probe housing is fixedly installed with a smoke inlet, and the other end of the flue gas probe housing is fixedly installed with a smoke outlet. The smoke inlet and the smoke outlet are respectively communicated with two legs of the U-shaped flue gas channel.

[0010] In summary, the technical effects and advantages of the present utility model are as follows:

[0011] In the present utility model, the flue gas enters the foot of one leg of the U-shaped flue gas channel through the flue gas inlet, and then is detected by the flue gas detection sensor at the end of the U-shaped flue gas channel. The flue gas is discharged from the flue gas outlet, so that the flue gas can be fully detected. After detection, high-pressure gas can be introduced through the high-pressure air pipe. The high-pressure gas blows from the first air blowing port to the inner wall of the U-shaped flue gas channel to clean the inner wall, and the high-pressure gas blows from the second air blowing port to the outer surface of the flue gas detection sensor to clean it. The impurities blown off can be discharged from the flue gas inlet and the flue gas outlet, eliminating the need for manual cleaning and improving the maintenance efficiency.
