Description

Technical Field

[0001] The utility model relates to the technical field of coke powder cooling, in particular to a novel coke powder cooling device. Background Art

[0002] Coke powder is the undersize of coke. It can be used as fuel in metallurgy, glass, ceramics and other industries. When petroleum coke powder is directly sprayed into the kiln for combustion, special technical measures must be adopted to fully heat and pyrolyze the fixed carbon particles, and through reasonable air distribution, the petroleum coke powder can be quickly ignited and burned. The main combustion processes used are high-temperature air combustion and oxygen-enriched combustion;

[0003] The coke powder cooling device is located at the bottom of the primary dust collector, and consists of a top pre-storage box, a middle cooling box, and a bottom discharge cone. It is used to store and discharge the high-temperature coke powder captured by the primary dust collector after cooling. The pre-storage box is the part of the entire structure that is subjected to the highest temperature and the strongest coke powder erosion. At present, the mainstream structure has added protective measures to the inner wall of the box, such as adding wear-resistant castings, etc., but there is almost no special protection for the cooling box;

[0004] At present, the mainstream structure of most coke powder cooling devices on the market has added protective measures to the inner wall of the box, such as installing wear-resistant castables, but there is almost no special protection for the cooling box. During the production process, the welds at the upper end of the coke powder cooling pipeline are easily eroded by coke powder or cracked when the coke powder discharge is too large and does not play a buffering role. At the same time, too much coke powder accumulates together, which makes it difficult to cool down the heat in the middle of the coke powder, resulting in poor cooling effect. Utility Model Content
