改進氧化鐵脫硫劑的配制原料!

  改進氧化鐵脫硫劑的配制原料,采用不易腐爛的稻殼替代木屑,這樣不僅可以改善脫硫劑的透氣性能,而且稻殼中的磷不易游離出來形成易自燃的白磷,從而從根本上消除自燃的起因。

  In this way, not only the air permeability of the desulfurizer can be improved, but also the phosphorus in the rice husk is not easy to dissociate to form the white phosphorus which is easy to self ignite, thus fundamentally eliminating the cause of self ignition.
  對于來說,要實現總氮的完全去除,反硝化過程是很重要的環節,有效降低硝態氮的步驟,要引起足夠的重視。總氮處理總氮去各類除磷劑原理揭秘總氮處理,如何達標?各類除磷劑原理揭秘常見的廢水除磷劑大致可分為四類:鈣鹽、鐵鹽、鋁鹽、鎂鹽。
  In order to remove the total nitrogen completely, denitrification is an important step. The steps to reduce the nitrate nitrogen effectively should be paid more attention. How to reach the standard of TN treatment? There are four kinds of dephosphorizers: calcium salt, iron salt, aluminum salt and magnesium salt.
  他們的工作原理雖有相同之處,但在細枝末節處也有不同。只有清楚的了解了各項原理,才能更有針對性的選擇除磷劑。鈣鹽常用的鈣鹽有Ca(OH)2和CaCl2。鈣鹽進入水中之后,鈣離子與磷酸根結合生羥基磷灰石Ca5(OH)(PO4)3沉淀。根據Ksp溶度積公式計算可得出,當pH=5~10之間時羥磷灰石溶解度小,沉淀效果。根據實驗可以看出石灰的除磷效果優于氯化鈣,但是石灰的投加量很大。鐵鹽常用的鐵鹽有FeSO4和FeCl3。
生物脫硫
  Although they work in the same way, they also differ in details. Only when we have a clear understanding of the principles, can we choose more targeted dephosphorization agents. Calcium salts commonly used are Ca (OH) 2 and CaCl2. After the calcium salt enters into the water, the calcium ion combines with the phosphate to form the hydroxyapatite Ca5 (OH) (PO4) 3 precipitation. According to the calculation of KSP solubility product formula, when pH = 5 ~ 10, the solubility of hydroxyapatite is small and the precipitation effect is good. It can be seen from the experiment that the phosphorus removal effect of lime is better than that of calcium chloride, but the dosage of lime is very large. The commonly used iron salts are FeSO4 and FeCl3.
  改進出箱(塔)保護措施,為減少出箱開蓋后,脫硫劑再生反應的放熱能量,應從減少在出箱時的再生反應著手,在出箱前先往脫硫箱(塔)內通入一定量的水蒸氣,使脫硫劑顆粒外壁形成一層水保護膜,從而減少再生反應,達到減少再生反應放熱的目的。
  In order to reduce the heat release energy of the regeneration reaction of the desulfurizer after the lid is opened, a certain amount of water vapor should be introduced into the desulfurizer before it leaves the tank to form a water protective film on the outer wall of the desulfurizer particles, so as to reduce the regeneration reaction and the heat release of the regeneration reaction.
