Description

Technical Field

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

[0002] A large amount of sintering flue gas containing sulfur compounds and nitrogen compounds will be generated during the industrial production process. These flue gases will enter the atmosphere, pollute the environment, cause great damage to the atmosphere, and even threaten people's health. Therefore, this gas needs to be treated and can only be discharged into the atmosphere after it passes the test.

[0003] The publication (announcement) number is CN211612252U, which discloses a flue gas desulfurization and denitrification treatment system for a thermal power plant, including a treatment box and a water bucket, the top of the treatment box is fixedly connected with a slide rail, and one end of the slide rail is connected with an air suction pump through a transmission motor. This utility model is convenient for when the flue gas enters the treatment box, the gas enters the limit plate through the sealing hole, and the limestone box and the water outlet valve work respectively at this time. The limestone box releases limestone powder and falls on the limit plate. The water outlet valve is opened to allow water to enter the limit plate from the water outlet pipe. At this time, the limestone powder is added with water to form a slurry as an absorbent to react with sulfur dioxide in the flue gas to generate calcium sulfate. After the calcium sulfate reaches a certain saturation, it crystallizes to form dihydrate gypsum, achieving the effect of desulfurization. The disassembly plate is convenient for disassembly, so that the limit plate can be taken out from the inside of the treatment box for convenient treatment.

[0004] Although the above scheme can desulfurize and denitrify the flue gas, the catalytic treatment components for nitrogen-containing compounds in the flue gas are fixed inside the device. After long-term use, it is difficult to clean and maintain the catalytic treatment components. The transmission structure such as the transmission motor and the slide rail cooperates with the shifting of the flue gas exhaust assembly to fully discharge the flue gas, which can easily lead to flue gas leakage and affect the treatment effect. For this reason, we propose a sintering flue gas denitrification treatment device. Utility Model Content
