Abstract
The utility model relates to a calcination system of an energy-saving rotary kiln. The existing calcination system of the rotary kiln is lack of a high-temperature gas residual heat recovery device, so that heat in high temperature waste gas exhausted from the rotary kiln can not be recycled. The calcination system of the energy-saving rotary kiln comprises the rotary kiln, fuel gas enters from the low end of the rotary kiln and exits from the high end of the rotary kiln; raw materials enter from the high end of the rotary kiln and exit from the low end of the rotary kiln, and the calcination system of the energy-saving rotary kiln is characterized in that the high end of the rotary kiln is communicated with a heat recovery chamber, a feed preheating pipe which is communicated with the rotary kiln is arranged in the heat recovery chamber, the raw materials are preheated by the preheating pipe and then enter into the rotary kiln. The design can realize that the raw materials firstly pass through the feed preheating pipe for absorbing heat from the high-temperature waste gas for drying and increasing the temperature before entering into the rotary kiln. The calcination system of the energy-saving rotary kiln has the advantages of simple structure and obvious energy-saving effect, thereby being applicable to calcination of a variety of powder materials, in particular to production of aluminium oxide by calcination.
Description
Technical field
The utility model relates to a kind of energy-conservation calcined by rotary kiln system.
