Description

Technical Field

[0001] The utility model relates to the technical field of flue gas denitration, in particular to a high-clean denitration device. Background Art

[0002] There are two main types of flue gas denitrification technologies: dry and wet. Compared with wet flue gas denitrification technology, the main advantages of dry flue gas denitrification technology are: low basic investment, simple equipment and process, high efficiency of removing NOX, no wastewater and waste treatment, and not easy to cause secondary pollution.

[0003] In order to denitrify the flue gas, manufacturers often use catalytic reduction SCR denitrification to perform denitrification operations. In this case, the economical use of catalysts becomes the best means for enterprises to control costs. Before denitrifying the flue gas, by analyzing the flue gas, the amount of catalyst can be controlled according to the NOX content, thereby saving the catalyst. For this purpose, a gas analyzer is required to analyze the gas composition. Since a large amount of particulate matter and water vapor are mixed in the flue gas, the above substances need to be separated before gas analysis.

[0004] Existing gas analysis devices have the following disadvantages: 1. They are only equipped with coarse filters or fine filters, which means that they can only filter coarse or fine particles. When only coarse filters are configured, fine particles leaking through will still interfere with the measurement of flue gas, and are only suitable for high-concentration flue gas measurement conditions that are insensitive to interference. When only fine filters are configured, the filters are prone to clogging, requiring frequent maintenance, which increases labor costs. 2. Failure to equip the device for handling water vapor interference will cause water vapor to enter the instrument directly with the sample air. This will seriously interfere with the measurement of flue gas, and water vapor will condense inside the instrument, causing data measurement deviations and instrument failures. Therefore, a high-cleanliness denitrification device is needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a high-cleanliness denitrification device, which has the advantages of fully covering and filtering particulate matter in the flue gas and reducing the water vapor content in the flue gas, and solves the shortcomings existing when a coarse or fine filter is configured separately and the problem of data measurement deviation and instrument failure caused by failure to remove water vapor.
