[0002] Acid mist usually refers to misty acid substances. The particles of acid mist in the air are very small, smaller than those of water mist and higher than the humidity of smoke. The particle size is 0.1 to 10 microns. It is a substance between flue gas and water mist and is highly corrosive. It includes acid mist formed by inorganic acids such as sulfuric acid, nitric acid, and hydrochloric acid and organic acids such as formic acid, acetic acid, and propionic acid. Acid mist is easily generated in industrial production. Acid mist needs to be sprayed with alkaline solution during the treatment process. The current traditional method is to spray the acid mist in the box with alkaline solution and then discharge it.

In this case, it is usually necessary to dilute the alkali solution to an appropriate concentration before adding it.

[0004] However, the existing dilution equipment is to dilute by driving the stirring mechanism through a motor after adding water, but the installation of the motor increases the processing cost of the equipment and has low practicality. Therefore, those skilled in the art provide an automatic alkali solution adding device for an acid mist absorption tower to solve the problems raised in the above background technology.
