Embodiment 1

[0018] The beam type lime kiln of the present invention such as figure 1 As shown, it mainly includes a kiln body 21, a feeding system, a combustion system, a discharging system, an air supply system and a control system. The kiln body includes a feed inlet, a preheating zone 3, a calcining zone 4, a cooling zone 6 and a discharge port. Two suction beams 2 are arranged on the upper part of the preheating zone. The calcining belt 4 is equipped with upper and lower two-layer combustion beams 5, the upper layer is provided with 3 combustion beams 5, and the lower layer is provided with 2 combustion beams, and the combustion beams are "T" type combustion beams. The beam body is provided with a fuel pipeline and an air channel, both of which are box-shaped, and the fuel pipeline passes through the air channel. The fuel pipeline is connected to the burners, which are gas fuel burners, and the burners are arranged on both sides of the combustion beam, with 10 burners on each side. ...

Embodiment 2

[0021] Another embodiment of the present invention is as figure 2 As mentioned above, the cooling zone of the beam type lime kiln is provided with two cooling air inlets, namely the cooling air inlet 8 and the upper cooling air inlet 7 . The cooling fan 19 is divided into two paths, one path is connected to the cooling air inlet 8, and the other path is connected to the upper cooling air inlet 7 through the heat transfer oil cooler. The connecting pipeline is provided with a valve 18 for adjusting the air volume entering the heat transfer oil cooler. The outlet of the upper suction beam 2 is divided into two paths, one path is connected to the exhaust gas discharge system through the flue gas / gas heat exchanger 10, and the other path is connected to the exhaust gas emission system through the flue gas / air heat exchanger. In this embodiment, the heat transfer oil is used to exchange heat with the cooling air entering the cooling zone, and the heat is brought into the kiln bod...

Abstract

The invention provides a beam limekiln, which mainly comprises a kiln body, a burning system, a discharging system, an air supply system and a control system, wherein a cooling belt of the kiln body is provided with an upper layer of burning beams and a lower layer of burning beams, and the burning beam is provided with a cooling system; and the cooling system comprises a cavity between a beam body and an outer wall, a connecting pipeline, a conducting oil circulating pump and a conducting oil cooler, and the conducting oil cooler comprises an oil way and an air pipeline. The conducting oil cooler is connected with a preheating air pipeline or a fuel gas pipeline or a cooling air pipeline of the cooling belt, and exchanges heat with hot combustion air or fuel gas or cooling air so as to recover heat discharged by cooling the conducting oil of the burning beam, thereby saving energy, reducing energy consumption and production cost and improving economic efficiency. The invention has reasonable flow and more optimized production operation.

Description

technical field [0001] The invention belongs to the technical fields of building materials and chemical machinery, and relates to a kiln for calcining materials, in particular to an improvement of a beam type lime kiln. Background technique [0002] Calcining limestone with beam kiln is a new technology for lime production. The beam type lime kiln has the advantages of low energy consumption, good quality of lime products, strong production capacity, large operating flexibility, etc., and is widely used in lime production for metallurgy, chemical industry and other purposes. The combustion beam is the core equipment of the beam-type lime kiln. The beam body of the combustion beam is equipped with burners, fuel pipelines and combustion-supporting air pipelines. The fuel and combustion-supporting air are delivered to the burner through the fuel pipeline and the combustion-supporting air pipeline. The burner evenly distributes the fuel and burns it. The combustion beam works a...
