Vertical preheater
Vertical preheater is one of the main active lime equipment, the main effect of vertical preheater is the limestone material sent to the preheater, and use high temperature exhaust gas from the kiln calcining out emissions(1150 degrees Celsius), the material in the preheater evenly heated to about 900 degrees Celsius.In the preheating process of 30%CaCO3 is under preheater decomposition, and then by the hydraulic push rod into the rotary kiln calcination, calcination process that not only makes the limestone calcination time in the kiln is greatly shortened, obtain higher activities of lime.
Vertical preheater system mainly consists of six parts.
1. Feeding system: mainly including the upper house, the discharge pipe, the materials and structure that can guarantee the body feeding safety sealed in preheater, so that the outside of cold air cannot enter into preheater inside, and material feeding can use stick valve to achieve continuous or intermittent feeding.
2. Preheater: it is the most important part of ensuring the material preheated to 900 degrees Celsius, which is composed of a preheating chamber, a suspension device and a refractory lining (this does not belong to the scope of equipment design and manufacturing) and other parts. This part of the structure is mostly metal component material selection, part of the heat-resistant steel according to the needs, working at 1000~1100 degrees Celsius high temperature heat-resistant steel. In addition, the refractory lining structure has the advantages of novel design, good sealing performance, can ensure material in preheater evenly preheated and achieve preheating temperature.
3.The pushing device: mainly including pusher, frame and the connecting rod part, pusher heat-resistant steel casting or welding to become, can withstand high temperatures, with the help of electric and hydraulic system, the hydraulic push rod can be automatic control procedures followed by pushing.
4. Hydraulic system: mainly comprises an oil tank, pump, motor, electromagnetic valve, hydraulic tubing, his main role is to control the pushing device, complete the pushing action.
5. Charging room: mainly including the chute feeding chamber, charging spout, body, its main function is to the material into the rotary kiln preheated calcined within.
6. framework: It includes columns, ring beams , the main role is to carry the upper structure of the preheater
