Description

Technical Field

[0001] The invention relates to a waste heat recovery system, in particular to a waste heat recovery system for a high-temperature mineral material uniformly ventilated vertical cooling kiln. Background Art

[0002] At present, in order to recover the waste heat of high-temperature sintered ore, some steel mills have begun to try to use vertical cooling kilns instead of ring coolers. The main body of the vertical cooling kiln is a feed bin and a heat exchange bin of a cylindrical structure arranged up and down, and an air outlet device, a discharging device and an air blower are installed in the heat exchange bin. When working, the high-temperature ore enters the heat exchange bin from the feed bin through the material transfer pipe and accumulates, and moves from top to bottom by its own weight under the action of the discharging device. The low-temperature gas is blown in from the air blower at the bottom of the kiln body, flows from bottom to top, exchanges heat with the high-temperature ore in countercurrent, and becomes high-temperature flue gas and flows out from the air outlet device.

[0003] In order to better recover the waste heat of high-temperature cement clinker, some cement plants are also using vertical cooling kilns to recover the waste heat of high-temperature cement clinker. The main body of the vertical cooling kiln is a two-stage cylinder structure; the upper section quickly cools the ultra-high temperature cement clinker just out of the rotary kiln, and the lower section cools the high-temperature cement clinker normally.

[0004] The invention is used for the vertical cooling kiln of steel plant and the lower section of the vertical cooling kiln of cement plant, and has reasonable heat exchange principle, good sealing and high efficiency. The above-mentioned prior art blast device is composed of a central hood with an air outlet, a blast cone, an air duct, and upper and lower annular air chambers. Its shortcomings are: the air outlet area is concentrated and the air cannot be distributed evenly; at the same time, a high-temperature ore pile with a convex top will inevitably be formed during feeding, which makes the thickness of the high-temperature ore in the heat exchange bin in each vertical direction vary greatly; at the same time, the high-temperature ore is composed of particles with a particle size of 1mm-150mm. During feeding, coarse particles will quickly roll to the edge position according to the outer side of the high-temperature ore pile, while fine particles will remain in the central area. Even if the height of the high-temperature ore in the vertical direction is consistent, the gas resistance of the high-temperature ore column in the vertical direction per unit cross-sectional area is small in the peripheral area and large in the central area; and the existing feeding method makes the high-temperature ore in the central area thick and the high-temperature ore in the peripheral area thin; the above two points make the gas resistance of the high-temperature ore column per unit cross-sectional area in the heat exchange bin according to the blast direction vary greatly, causing serious eccentric wind; the high-temperature ore cannot be evenly cooled, the outlet air temperature is low, the outlet ore temperature is high, and the residual heat recovery efficiency is low; in addition, the blast and / or induced air pressure is high, and the energy consumption is high.
