Embodiment 1
[0020] The sodium hypochlorite generating process is in the form of a frame-type natural circulation, which occurs continuously for 240 hours each time.
[0021] Described a kind of small-scale sodium hypochlorite generator that is used for sewage treatment handles water capacity is 2.5 tons / hour.
[0022] The described corrosion-resistant porous cermet material is prepared according to the following scheme:
[0023] According to the number of parts by mass, 24.6 parts of nickel oxide and 33 parts of iron oxide were added to 150 parts of deionized water, pre-mixed with a stirrer for 25 minutes, and then controlled at 50 °C for 8 hours in a planetary ball mill; Put the slurry into a mixing kettle, add 2.5 parts of potassium fluoroborate and 3 parts of potassium titanate, stir rapidly for 40 minutes, then dry the slurry in a drying oven at 140°C for 3 hours, and dry the obtained solid in a muffle Sinter in a furnace at 1000°C for 5 hours; after sintering, pulverize to obtain a ...
