Waste incineration power generation boiler flue gas pollutant monitoring device the

Abstract

The invention discloses a waste incineration power generation boiler flue gas pollutant monitoring device in the technical field of flue gas pollutant monitoring, and the device comprises a smoke exhaust pipeline, a mounting ring is arranged at the top of the smoke exhaust pipeline, a protection top is fixedly connected to the top of the mounting ring, and the front side of the smoke exhaust pipeline communicates with a detection channel. The front side of the detection channel extends to the outer side of the smoke exhaust pipeline. According to the invention, the detection probe is sent into the smoke exhaust pipeline by using a mounting block and a mounting plate, the inclined surface at the rear end of the mounting plate acts on the inclined surface at the bottom end of the first sealing plate, and the bottom of the first sealing plate slides on the upper surface of the mounting plate, so that the situation that smoke enters the exhaust pipeline in the process of pushing the detection probe into the smoke exhaust pipeline and the detection is inaccurate is prevented, and then, when the mounting plate is completely pushed into the smoke exhaust pipeline, a stop block can abut against the front side face of a second sealing plate, smoke is prevented from escaping in the detection process, and the accuracy of smoke detection by the detection probe is improved.

Description

technical field [0001] The invention relates to the technical field of flue gas pollutant monitoring, in particular to a flue gas pollutant monitoring device for waste incineration power generation boilers. Background technique [0002] In the power industry, incineration power generation will generate and emit a large amount of flue gas. Carbon monoxide, sulfur dioxide, sulfur trioxide and nitrates in the flue gas are extremely harmful to the ecological environment and human body. During the operation of the boiler, in order to understand The degree of incomplete combustion in the furnace is convenient to adjust the combustion situation, and various components in the flue gas need to be monitored. When detecting the flue gas in the chimney, it is necessary to extend the measuring probe into the inside of the chimney, and then measure various real-time data of the flue gas in the chimney through the measuring probe. [0003] In the prior art, some invention cases of flue ga...

Problems solved by technology

[0006] The object of the present invention is to provide a waste incineration power generation boiler flue gas pollutant monitoring device to solve the above-mentioned background technology. Monitor, and then obtain the composition of the smoke through the detector. When the detection probe is extended into the smoke exhaust port for monitoring, the smoke at the smoke exhaust port will be diluted by air, which will affect the accuracy of the detection.
