Embodiment Construction

[0043] Such as figure 1 As shown, the car-type rapid reaction furnace is composed of furnace body, furnace car and cooling system under the car; 300; the preheating section is provided with a smoke exhaust system, the combustion section is provided with a combustion system, and the cooling section is provided with a cooling system.

[0044] Such as figure 2 and image 3 As shown, the body of the car-type rapid reaction furnace of the present invention is composed of a furnace wall 1 and a furnace roof 2 . In order to reinforce the furnace body, a steel frame structure 3 is provided in the furnace body.

[0045] The function of the furnace wall is:

[0046] a. Together with the furnace roof and furnace car lining bricks, it forms the furnace path. The temperature in the furnace, especially the combustion section, is very high, so the furnace wall must withstand high temperature for a long time;

[0047] b. The temperature difference between the inside and outside of the ...

Abstract

The invention discloses a quick vehicle-type reacting furnace which is formed by a furnace body, a furnace vehicle and an under-vehicle cooling system, wherein the furnace body comprises furnace walls and a steel structure of a furnace top and inside the furnace and is formed by a preheating section, a combustion section and a cooling section; the preheating section is provided with a purging system; the combustion section is provided with a combustion system; and the cooling section is provided with a cooling system. The quick vehicle-type reacting furnace provides a new energy-saving and environmentally-friendly path for comprehensively utilizing low-grade nickel ores. Coal derived reducing agent is added to the dried and smashed Laterite-nickel ores; ingredients are mixed evenly and then put into a kiln car container of the quick vehicle-type reacting furnace; and the reduction roasting is carried out in the quick vehicle-type reacting furnace at the temperature of 900-1350 DEG C.

Description

technical field [0001] The invention relates to a car-type fast reaction furnace. Background technique [0002] The car furnace is a relatively advanced furnace widely used in ceramics, refractory, direct reduced iron (DRI) and other industries. Its kiln chamber is tunnel-shaped, with a furnace roof on the top, furnace walls on both sides, and a track on the bottom. There are furnace cars loaded with products on the rails. The furnace car is covered with refractory lining bricks to form a movable furnace bottom. The material to be roasted is loaded on the furnace car, enters the furnace from the furnace head with the furnace car, is heated in the furnace, undergoes a series of physical and chemical changes, and becomes a finished product. After cooling, it is pushed out of the furnace following the furnace car. [0003] The car-type furnace has the advantages of high output, low fuel consumption, stable firing system, good working conditions, low labor intensity, easy mecha...
