Vertical preheater for calcination process equipment

Vertical preheater is zk corp engineering and technical personnel in the introduction and absorption of foreign advanced technology, based on the combination of dolomite calcination characteristics, developed for preheating raw materials vertical preheating device, with a reasonable structure, high heat exchange rate, and high automation level, mainly used for preheating thermal stability of dolomite. Vertical preheater and rotary kiln supporting usage can be high-temperature flue gas to make full use of waste heat, play a role in energy saving, energy-saving environmentally friendly products.
20-50mm dolomite from the belt conveyor to the vertical preheater top silo, under the action of gravity through the cutting chute to the vertical preheater, from the rotary kiln high temperature gas through the transport chute into the vertical preheating equipment, and dolomite for heat exchange. The material preheated to 800 ℃ above, after the heat exchange of gas through the exhaust pipe into the dust collector, preheated dolomite pushed through the hydraulic push rod to the discharge port through the transport chute to the rotary kiln.
Vertical preheater structure is simple, mainly by the upper feeding system, ceiling device, preheater body, push material system, hydraulic system and other components. With advanced processing capacity and technical level, our vertical preheater has its unique advantages:
1. Environmental protection, energy saving, rotary kiln installed vertical preheater, the thermal efficiency increased by 30%, smoke dust content is reduced to 30mg / m³ below.
2. The usage of vertical preheater, can shorten the length of the rotary kiln, reducing the area and kiln body surface heat, production capacity can be increased by 20% or more.
3. Low operating costs, as the push head and the main parts of the body are heat-resistant steel, can be 1000 ~ 1100 ℃ high temperature long-term work, with a long service life.
4. Refractory brick lining design novel, good sealing, to ensure uniform preheating materials to improve the quality of finished products.
