Description

Technical Field

[0001] This utility model relates to the field of flue gas acid production technology, and in particular to a liquid addition device for a circulating tank of flue gas acid production using ion liquid desulfurization method. Background Technology

[0002] Ionic liquid desulfurization is a technology that uses ionic liquids as absorbents for flue gas desulfurization. Ionic liquids are aqueous solutions composed of organic cations and inorganic anions, typically with the addition of small amounts of activators, antioxidants, and corrosion inhibitors. Its working principle is as follows: at room temperature, the ionic liquid absorbs sulfur dioxide, while at high temperatures, it releases the absorbed sulfur dioxide, thus achieving sulfur dioxide removal and recovery. When using flue gas to produce acid, liquid needs to be added inside the circulating tank. Currently, during the liquid addition process, acid mist is generated and directly contacts the inner wall of the tank, easily causing corrosion. Furthermore, uneven liquid addition can lead to localized crystallization inside the tank. Therefore, those skilled in the art provide an ionic liquid desulfurization flue gas acid production circulating tank liquid addition device to solve the problems mentioned in the background art.

When the rotating rod 51 rotates, it will drive the stirring rod 52 to rotate inside the mixing cylinder 2, and the rotating plate 53 at one end of the rotating rod 51 will support the rotating rod 51.

After the filter plate 93 slides to the appropriate position, the telescopic rod 94 inside the locking groove will drive the positioning block 96 to reset through the spring 95. The positioning block 96 will then lock into the inside of the installation groove, with the top of the positioning block 96 contacting the bottom of the pressing block 97. The operator can then complete the installation of the filter plate 93. When it is necessary to remove the filter plate 93, press the pressing block 97, and then pull the filter plate 93 out through the limiting tube 92.
