Description

Technical Field

[0001] The utility model relates to the technical field of demisters, in particular to a silicon carbide nozzle. Background Art

[0002] The demister is mainly composed of corrugated blades, plates, strips and other fixing devices. In wet flue gas desulfurization, the absorption tower is prone to produce "fog" with a particle size of 10-60 microns during operation. The "fog" not only contains water, but also contains sulfuric acid, sulfate, sulfur dioxide, etc. It also causes contamination and serious corrosion of fans, heat exchangers and flues. Therefore, the wet flue gas desulfurization process requires demisting of the absorption equipment, and the purified gas must be demisted before leaving the absorption tower. The demister nozzle is one of the main components of the demisting system. The demister nozzle is mainly made of high-quality plastic, which has extremely high wear resistance and long service life.

[0003] The existing patent publication number is CN217043039U, which discloses a wear-resistant and corrosion-resistant silicon carbide-based ceramic nozzle, including a sleeve, the inner wall of the sleeve is provided with a through cavity; a connector threadedly connected to one end of the sleeve, and the connector and the outer wall of the sleeve are provided with a wrench position for a wrench to twist. The utility model greatly simplifies the difficulty of production by arranging the nozzle insert and the swirl blade to be separated from the sleeve, and the installation is also very convenient. At the same time, if wear occurs in the later stage, only the worn part needs to be replaced, and the whole part does not need to be replaced, which greatly saves production costs. Through multiple sets of gaskets that are tightly pressed between the connector and the blade frame and the nozzle insert to play a supporting role, the swirl components with different spiral heights can be replaced according to the different slurry components. Only the number of gaskets needs to be increased or decreased to completely replace the new swirl component, which is very convenient to use.

[0004] The existing silicon carbide nozzle needs to install or remove the bolts one by one during installation and removal, which is very troublesome and reduces the maintenance rate of the nozzle by the staff. Therefore, we propose a silicon carbide nozzle to solve the above-mentioned problems. Utility Model Content
