Description

Technical Field

[0001] This utility model relates to the field of flue gas detection technology, specifically to a flue gas concentration detection device for flue gas treatment. Background Technology

[0002] Flue gas concentration detection devices for flue gas treatment are professional equipment that play an important role in the field of environmental protection. They mainly use specific detection technologies and principles to accurately measure the concentration of various pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter in flue gas. Their purpose is to provide reliable data support for flue gas treatment work and assist regulatory authorities in ensuring that flue gas can be discharged in accordance with relevant standards.

[0003] The prior art discloses a flue gas concentration detection device for flue gas treatment, with application number 202323110250.4. The device includes an operating box with a ventilation port on the top. A pad is fixedly connected to the middle of the side of the operating box. A door panel is rotatably connected to the side of the operating box adjacent to the pad. A connection port is fixedly connected to the side of the operating box away from the pad. A switch box is fixedly connected to the side of the operating box adjacent to the connection port. A pipe carrying flue gas is inserted into the connection port, and the detector is inserted into the detection cylinder inside the operating box. Pulling the lever slides the sealing plate, allowing flue gas to enter the operating box. The detector detects the flue gas. After detection, the flue gas pipe is pulled out, and the sealing plate automatically closes under spring pressure. The blower and filter are started, and purified flue gas is discharged from the ventilation port. Compared with the prior art, this device provides sealed detection protection and facilitates instrument operation.

[0004] However, the existing technology still has the following shortcomings. First, when the above-mentioned device is used, it can protect the detection instrument by setting up a sealed sampling space. However, the above-mentioned device cannot be directly installed on the flue. A long sampling pipe needs to be set up to connect to the flue. For high-temperature industrial flue gas, if the sampling pipe is too long and there is no good heat preservation measure, the temperature of the flue gas will drop too quickly during the transmission process, which may cause some gaseous pollutants to condense, be adsorbed, etc., changing their concentration in the sample, thus bringing errors to the detection results.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flue gas concentration detection device for flue gas treatment, comprising a detection mechanism and a sampling mechanism, wherein the sampling mechanism is fixedly connected to the side of the detection mechanism.

This can more accurately reflect the true concentration of the flue gas and provide a reliable basis for flue gas treatment.
