Of magnesia wet desulfurization water treatment system

First of magnesium oxide in the mixing time to join in can play a stabilizing role, can prevent scorch processing, and improved the rubber in the storage process of the coke burning and plastication, also has the effect of plasticized rubber.

The addition of Magnesium Oxide to the rubber at the beginning of mixing can prevent the early crosslinking and cyclization of the chloroprene rubber, and can increase the safety of the operation. At the time of vulcanization, it becomes a vulcanizing agent, which acts as a hydrogen chloride receptor to prevent the corrosion of hydrogen chloride on fibrous tissue. Magnesium Oxide can improve the heat-resistant and aging resistance. The quality of Magnesium Oxide has a great influence on the processing and vulcanization of chloroprene rubber. When the amount of Magnesium Oxide is increased to 10, it can make the colloid high plasticity and better storage stability.

Zinc Oxide is mainly made of vulcanizate, which can make the vulcanization flat. Increasing the amount of Zinc Oxide, although it can improve the heat-resistant and aging resistance, but the adhesive is easy to burn and reduce the storage stability of the rubber. A large amount of use can also make the rubber hard and lose its plasticity. But it can increase the rate of vulcanization and increase the degree of vulcanization and high temperature resistance. In general, Magnesium Oxide and Zinc Oxide both use at the same time, so that the vulcanizate is easy to scorch, and the vulcanization degree is high and the curing speed is fast. The cross-linking degree is much higher than that of the single use.

Magnesium Oxide wet desulfurization tower, the basic principle of calcium oxide desulfurization process and wet desulfurization process, the flue gas from the lower radial desulfurization tower into the reaction tower, in the process of reaction tower increase in contact with magnesium hydroxide slurry, sulfur dioxide and flue gas generated in the reaction of magnesium hydroxide to achieve desulfurization effect of Magnesium Sulfate, Magnesium Sulfate Asia belongs to the physical properties of insoluble the material in the oxidation under the action of the fan into Magnesium Sulfate.

  At the same time, the harmful gases, such as SO3, HCl and HF in the flue gas, are also absorbed in the absorption tower and dissolved into the slurry. With the consumption of magnesium hydroxide in the desulfurization tower, the pH value will decrease. It is necessary to continuously add fresh slurry to the desulfurization tower, and the products of desulfurization reaction need to be regularly discharged. Because the main components of Magnesium Oxide wet desulphurization products are sub Magnesium Sulfate and Magnesium Sulfate, calcium sulfate is different from calcium sulphate desulfurization. Calcium sulfate has low solubility. It can produce high purity gypsum by vacuum belt conveyor after swirling, and gypsum market is wide. But for Magnesium Oxide products for wet desulfurization and Magnesium Sulfate Magnesium Sulfate, Magnesium Sulfate and Magnesium Sulfate with high solubility, sub content changes in the operating conditions the oxidation fan is larger, can not achieve the high purity of Magnesium Sulfate or Magnesium Sulfate products and sub, extraction because the purity is not up to the requirements of the market prospects. So, the two desulfurization tower discharge slurry treatment system is not set vacuum belt machine to extract products achieve the purpose of comprehensive utilization, and the desulfurization tower slurry discharge directly into the desulfurization wastewater treatment system, and discharge large, solid content in the slurry with high temperature (53 DEG C), low pH, waste water and other unfavorable factors brought great the difficulty for the treatment process of desulfurization wastewater.
