Abstract
Description
【０００１】本発明は、水酸化カルシウムと水酸化マグ

したものである。[0001] The present invention uses a solid particle composed of calcium hydroxide and magnesium hydroxide to reduce the size of the air polluted air so that sulfur oxides and nitrogen oxides contained therein can be efficiently removed, and to purify the air. It is made available to machines.
【０００２】従来、大気汚染空気中に含まれる硫黄酸化

・水酸化マグネシウムなどの水スラリーの中に大気汚染
空気を吹き込み除去する方法があるが、水スラリー撹拌
装置が必要であることや、吹き込みノズルの閉塞などの
問題があったため、小型化は困難であった。Conventionally, there is a method for removing sulfur oxides and nitrogen oxides contained in air polluted air by blowing air polluted air into a water slurry such as calcium hydroxide and magnesium hydroxide. However, there were problems such as the necessity of a water slurry stirring device and the blockage of a blowing nozzle, so that miniaturization was difficult.

て水分を供給する。According to the present invention, first, a solid particle composed of calcium hydroxide and magnesium hydroxide is first reduced with sulfur oxides and nitrogen oxides in order to reduce the size by eliminating the conventional water slurry stirring device and the blowing nozzle. As an absorbent for the product. Since water does not coexist in this state, the reaction with these acidic gases does not proceed. Therefore, air is supplied to the air by blowing air polluted air into the water in advance, so as to contain saturated water vapor.

去する事ができる。[0004] In this way, it is possible to keep the surface and the inside of the solid particles composed of calcium hydroxide and magnesium hydroxide constantly in a wet state. In this way, since water coexists on the surface of the solid particles, a chemical reaction with sulfur oxides and nitrogen oxides occurs continuously, and sulfur oxides and nitrogen oxides can be efficiently removed from air polluted air. Can be.
