AMMONIA ADSORPTION MATERIAL FOR REDUCING AMMONIA VOLATILIZATION AMOUNT AND LIQUID LEVEL COVERING FLOAT THEREOF

To provide an ammonia adsorption material for reducing an ammonia volatilization amount and a liquid level covering float thereof.SOLUTION: An ammonia adsorption material comprises, by mass, 60-70 parts of modified cocoanut active charcoal, 15-20 parts of calcium superphosphate, 75-80 parts of zinc chloride, 3-8 parts of diatomite, 2-4 parts of sodium alginate, and 90-100 parts of ZIF-8 crystal powder. The liquid level covering float comprises a ball body 1 and a floating ring 2 sleeved outside a middle part of the ball body, an upper half part of the ball body is a cavity, a lower half part of the ball body is of a solid structure, a main plate is arranged at the center of the lower half part of the ball body, a plurality of slots 4 is symmetrically formed in the lower half part of the ball body on two sides of the main plate, and separators 5 coated with ammonia adsorption materials are arranged among the slots. The liquid level covering float according to the present invention is rich in pore structure and has good ammonia adsorption performance.SELECTED DRAWING: Figure 1 【課題】アンモニア揮発量を低下させるための吸着材料及びその液面被覆用フロートを提供する。【解決手段】アンモニア吸着材料は、変性ヤシ殻活性炭６０～７０重量部、過リン酸カルシウム１５～２０重量部、塩化亜鉛７５～８０重量部、珪藻土３～８重量部、アルギン酸ナトリウム２～４重量部、ＺＩＦ－８結晶粉末９０～１００重量部を含み、前記液面被覆用フロートは、球体１と、前記球体の中央部外に套設された浮きリング２とを含み、球体の上半部がキャビティであり、球体の下半部が中実構造であり、球体の下半部の中心に主板が設けられ、主板の両側の球体の下半部に複数の溝４が対称に設けられ、溝の間にアンモニア吸着材料が塗布されたセパレータ５が設けられる。本発明の液面被覆用フロートは、細孔構造に富んで、しかも良好なアンモニア吸着性能を有する。【選択図】図１
