Problems solved by technology

[0003] The existing rotary kiln needs to use the rotary kiln spray gun to supply air. When in use, the range and angle of the existing rotary kiln spray gun are fixed, and the air in the rotary kiln has a certain rotation and circulation. When the rotary kiln spray gun is used, there will be differences in the gas components in the local air, which will not be a big problem in ordinary calcination, but it is easy to cause calcination defects in the finished product during fine calcination

Abstract

The invention discloses a rotary kiln spray gun gas supply device which comprises a plurality of gas supply layers annularly arranged in a sleeving manner. The gas supply layers sequentially comprisethe center ventilation layer, the first gas flow layer, the first outer ring ventilation layer, the second gas flow layer and the second outer ring ventilation layer from inside to outside. The innerside faces of the center ventilation layer, the first outer ring ventilation layer and the second outer ring ventilation layer are provided with gas guide strips spirally extending along the annular faces. The first coal gas flow layer and the second coal gas flow layer are each provided with a plurality of coal gas flow through holes supplying gas in the circumferential direction. Tail end connecting plates are arranged at the tail ends of the gas supply layers. According to the rotary kiln spray gun gas supply device, gas components in a rotary kiln can be effectively improved, and the gas concentration in the whole rotary kiln is more balanced.

Description

technical field [0001] The invention relates to the field of rotary kiln equipment, in particular to a rotary kiln spray gun air supply device. Background technique [0002] Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which is similar in appearance to rotary bed, also called rotary bed kiln, and belongs to the category of building materials and equipment. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials. Cement kilns are mainly used for calcining cement clinker, which can be divided into two categories: dry production cement kiln and wet production cement kiln. Metallurgical and chemical kilns are mainly used for magnetization roasting of lean iron ore in iron and steel plants in the metallurgical industry; oxidative roasting of chromium and nickel-iron ore; roasting of high-alumina bauxite in refractory plants and clinker and aluminum hydroxide in aluminum plants; roasti...
