b) 设备组成及特点Equipment composition and characteristics
竖式预热器是预热石灰石的关键设备。它由预热器本体、储料仓、加料管、液压推杆装置等组成。
Vertical preheaters are a key equipment for preheat limestone.It consists of preheater body, storage warehouse, feeding duct, hydraulic pushrod device, etc.
此型竖式预热器的一个突出特点是其内部设置有低阻力梁，它可以合理分布窑尾进入预热器的烟气气流，降低烟气在预热器中的阻力，从而减少排烟机的功率消耗。烟气在竖式预热器中直接穿过料层与石灰石进行热交换，充分利用高温热烟气的余热，使石灰石预热温度达到900℃，使石灰石预热并有一部分石灰石得到分解。废气经过热交换后排出温度较低（最低可小于235℃），有利于除尘净化装置的选型；预热器采用12个液压推头向回转窑内加料。预热器顶部设有一个料仓，料仓上设有料位计控制料层高度；料仓和预热器本体之间设有溜料管，其作用一是将顶部料仓的石灰石送入预热器内，二是起料封作用防止冷空气进入预热器内。预热器内除顶部采用吊挂砖外，其余部位均采用耐火浇注料，砖型少，砌筑简单；整个竖式预热器运动设备少，设备维护量小，运行稳定可靠。
A prominent feature of this vertical preheater is its internal low resistance beam, which can reasonably distribute the flue gas airflow from the kiln tail into the preheater, reduce the resistance of the flue gas in the preheater, thus reducing the power consumption of the smoke exhaust machine.The flue gas directly through the material layer to heat exchange the limestone, make full use of the residual heat of the high temperature hot flue gas, make the limestone preheating temperature reach 900℃, make the limestone preheat and decompose part of the limestone.After heat exchange, the exhaust temperature is low (less than 235℃), which is conducive to the selection of dust removal and purification device; the preheater uses 12 hydraulic thrust heads to the rotary kiln.There is a material warehouse on the top of the preheater with a material level gauge controlling the height of the material layer between the material warehouse and the preheater body sends the limestone at the top into the preheater and the other is to prevent the cold air from entering the preheater.Besides the top, the preheater shall be refractory pouring with less brick type and simple masonry; the whole vertical preheater has less movement equipment, small equipment maintenance quantity and stable and reliable operation.
