Vertical preheater in cement plant is the preheating of the vertical preheating device that engineering and technical personnel in the introduction and absorption of foreign advanced technology, based on the calcining dolomite. It has the advantages of reasonable structure, high heat exchange rate, high level of automation features, mainly used for preheating thermal stability of dolomite. Vertical preheater supporting in rotary kiln, can make the kiln inlet high temperature flue gas waste heat fully utilized, and play a role in energy saving. Vertical preheaterin cement plant is energy saving and environmental protection product.
20-50mm dolomite from the belt conveyor to the top of the vertical preheater silo, under gravity through the chute to the vertical preheater, and the high temperature gas from the rotary kiln through the transfer chute into the vertical preheating device, and dolomite heat exchange. Preheating the material to higher 800 degrees centigrade or more, the heat exchange gas through the exhaust pipe into the dust collector, preheated dolomite pushed through the hydraulic push rod to the discharge port through the transfer chute to the rotary kiln.
ZK production of vertical preheater has simple structure, and mainly consist of the upper feeding system, ceiling device, preheater body, pushing the material system, hydraulic system and other components. With advanced processing capacity and technical level, the vertical preheater produced by ZK has its unique advantages:
1 Environmental protection, and energy saving. Rotary kiln installed vertical preheater, and the thermal efficiency increased by 30%, flue gas dust content is reduced to 30mg / m³ below.
2 Using vertical preheater, can shorten the length of rotary kiln, reducing the area and the heat dissipation of the kiln surface, then production capacity can be increased by 20%.
3 Low operating costs, as the key parts of the body and thrust head are heat-resistant steel, can long-term work in the 1000 ~ 1100 high temperature, which with a long service life.
4 Refractory brick lining design is new structure, good sealing, to ensure even preheating of materials, and improve product quality.
