Description

Limestone slurry drawer type deironing equipment

Technical Field

The utility model relates to a limestone production facility technical field, concretely relates to limestone slurry drawer type deironing equipment.

Background

At present, the environment protection situation is severe, and in order to meet the national requirements for environment protection, thermal power generation enterprises mostly adopt a limestone-gypsum wet desulphurization process. Limestone is the main component of calcium carbonate (CaCO 3). Lime and limestone are a large number of raw materials used in construction materials, industry. Limestone can be directly processed into stone and burnt into quicklime. The quicklime CaO absorbs moisture or is added with water to form slaked lime, the main component of the slaked lime is Ca (OH)2 which can be called as calcium hydroxide, and the slaked lime is blended into lime slurry, lime paste and the like. At present, the environment protection situation is severe, and in order to meet the national requirements for environment protection, thermal power generation enterprises mostly adopt a limestone-gypsum wet desulphurization process. The wet desulfurization requires that limestone particles be ground into limestone slurry by a wet ball mill (hereinafter referred to as a wet grinder) and used as an absorbent of a desulfurization system.

The wet desulfurization requires that limestone particles be ground into limestone slurry by a wet ball mill (hereinafter referred to as a wet grinder) and used as an absorbent of a desulfurization system. There is a loss of steel balls in the wet mill during operation. Although the related regulations clearly specify the steel ball loss, the steel ball loss in practical application is still large and far exceeds the regulations. According to statistics, 10 tons of steel balls are required to be added into a normally-running wet grinder every month, and the steel balls are more in loss. The steel ball generates metal scraps (most of the metal scraps, hereinafter referred to as scrap iron) during the collision process, the scrap iron enters the limestone slurry, the limestone slurry flows out from a slurry outlet of the wet ball mill, the slurry flow rate of the slurry outlet of the wet mill is not large, and the water content in the limestone slurry is higher at the moment; the iron chips enter a desulfurization system along with limestone slurry; the iron chips are not beneficial to the stable operation of the system. Part of scrap iron is discharged out of the system along with the dehydrated gypsum, so that the quality of the gypsum is influenced; part of scrap iron is oxidized in the system to generate ferric oxide, and the ferric oxide reacts and is finally left in the desulfurization wastewater in the form of heavy metal ions such as iron ions and the like to influence the treatment of the desulfurization wastewater; part iron fillings remain in desulfurization system, influence desulfurization system steady operation. Meanwhile, the loss of the steel balls can cause the waste of metal materials, and the production cost of enterprises is increased; based on the technical background, the inventor designs a drawer type iron removal device for limestone slurry; this device is to not getting into in the desulfurization system, being in the limestone slurry of liquid state deironing, improves desulfurization system operating stability, and then improves desulfurization efficiency, the separation of the magnet of being convenient for after the deironing simultaneously and iron fillings.
