The rotary vane vacuum pump - waste battery recycling technology

if not managed, used batteries will cause serious damage to the ecological environment. For example, when the soil, water and atmosphere by metal mercury or inorganic mercury pollution, some under the action of mercury in microbes, plants and animals, and the ultraviolet ray is converted into organic mercury enrichment, and thus damage to environment and human. Therefore, the processing of waste dry battery has been one of the focus of attention. Today the rotary-vane vacuum water pump are used in the waste battery treatment technology is a very good application.

waste batteries contain heavy metals such as mercury, cadmium, manganese, lead. When the surface of the waste battery corrosion by sunshine and rain, the inside of the heavy metal content will seep into the soil and groundwater. If people eat crops grown in contaminated land or drinking contaminated water, these toxic heavy metals ( 651329). Slow deposition in the body, pose a great threat to human health. Waste battery in the mercury spills, if enter human body cells are damaged, the human body nervous system will be severely damaged. Cadmium can damage the liver and kidney, in serious cases, will make their bones deformation. Some of the waste batteries also contains acid and heavy metal lead. If they leak into the environment, they can cause soil and water pollution, eventually harm the human.

rotary vane vacuum pump vacuum chloridizing roasting - Glass curing method and treatment of dry cell including crushing, magnetic separation, vacuum chloridizing roasting, cooling, adsorption, etc. In the process of roasting, when used batteries are crushed, waste batteries due to the internal heating will produce large amounts of gas. That sometimes, these gases will cause the battery explosion, explosion, damage to the equipment and cause serious consequences. Therefore, it is necessary to crush batteries before vacuum chloridizing roasting process.

the application of the rotary-vane vacuum water pump on the waste battery recycling

1. Rotary vane vacuum pump under low temperature baking. In the process of waste dry battery heating, water, ash, ammonium chloride and other materials can be distilled out constantly, paper, paste, etc will be ashing of organic compounds; As temperatures continue to rise, the remaining elements of the battery zinc began to melt, can be recycled use.

2。 Through rotary vane vacuum water pump chloride and roasting of waste dry cell calcined at low temperature, moisture, organic matter during this period, such as ammonium chloride was completely removed. Metal chloride with low melting point, good volatile and soluble in water, easy to recycle and use. Greatly save energy, reduce the processing cost of waste dry cell.
