Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooling panel, in particular to a cooling panel group device. BACKGROUND

[0002] With the gradual strengthening of the energy saving and environmental protection consciousness of enterprises, the exploration and research of the waste heat recovery of converter flue gas and dry dust removal process have become a major research direction of the current environmental protection industry. Converter steelmaking is an intermittent production mode. During the normal smelting production stage of the converter, the flue gas temperature is high, the flue gas volume is large, the dust content is large, the flue gas flow rate in the pipeline is high, and the CO content is high. In order to prevent the explosion of flue gas caused by high-temperature particles, it is necessary to separate high-temperature particles, especially micron-level particles (average particle size of 50 μm and above), before waste heat recovery, so as to ensure that no explosion occurs during the whole waste heat recovery stage. The sleeve-shaped particle trapping device based on inclined plate settling technology solves this problem.

[0003] The sleeve-shaped particle trapping device based on inclined plate settling technology separates particles by using full dry gravity settling technology. The device is of inner and outer sleeve structure. The flue gas enters the inner sleeve, is deflected, passes through multiple layers of inclined plates to realize particle trapping, and then flows out of the outer sleeve. The flue gas flow channel is provided with multiple layers of inclined plates, which increases the flue gas flow area, reduces the flue gas flow rate, improves the particle trapping efficiency, realizes the separation of micron-level particles, and eliminates the explosion hazard caused by particle sparks. However, the sleeve-shaped particle trapping device for cooling high-temperature flue gas is in a high-temperature environment, and there is no mature technology to cool the outer sleeve of the device while recovering the waste heat of high-temperature flue gas.
