The beneficial effect of the utility model is: in retort, aluminum phosphate remaining in the aluminum phosphate residue is hydrolyzed to hydrogen phosphide, the ozone oxidation hydrolysis that hydrogen phosphide is passed into is a phosphoric acid, and residual phosphine gas is cleaned the potassium permanganate solution absorption in the jar.Reach the purpose of hydrogen phosphide zero-emission.Waste liquid in the retort contains low concentration liquor potassic permanganate in phosphoric acid and the purification pot to be converted in the water in pouring farmland and get final product, not only pollution-free but also can reach and apply fertilizer and the effect of sterilization.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, be provided with even gas distribution device first in the said retort; Be provided with even gas distribution device second in the said purification pot; Be equipped with several passages on said even gas distribution device first and the gas uniform device second, said passage decentre distribution density far away is big more.
Adopt the beneficial effect of above-mentioned further scheme to be: the even gas distribution device of design, ozone and hydrogen phosphide are evenly distributed in absorption liquid, prolonged ozone and the hydrogen phosphide retention time in absorption liquid, improved the absorptivity of hydrogen phosphide; Passage decentre distribution density far away is tall and big more, guarantees that distribution of gas is more even.
Further, be respectively equipped with a section plate valve first, section plate valve second, section plate valve third, section plate valve fourth and section plate valve penta on said liquid discharging tube first, liquid discharging tube second, addition funnel first, addition funnel second and the bleeder pipe.
Adopt the beneficial effect of above-mentioned further scheme to be: cut the setting of plate valve, make easier for installation, operation is more flexible.
