Problems solved by technology
[0002] The traditional CDQ high-temperature coke powder cooling device is a single-structure three-pipe, and its defects are as follows: 1) The effective heat exchange area per unit weight of the equipment is relatively small, and the distance between the high-temperature coke powder and the cooling water in the center is relatively large, which needs to be increased The cooling time needs to increase the heat exchange area to increase the volume of the equipment; 2) Due to its structural design defects, the internal water pipes are easily damaged

The invention discloses a high-temperature coke powder cooling device. The high-temperature coke powder cooling device comprises a box, a water inlet pipe and a water outlet pipe, and further comprises a center pipe, an outer sleeve I and an outer sleeve II; the center pipe is positioned in the outer sleeve I; the outer sleeve I is positioned in the outer sleeve II; an upper-layer separation plate, a middle-layer separation plate and a lower-layer separation plate are arranged in the box; the top of the center pipe is connected with the upper-layer separation plate; the upper-layer separationplate, the middle-layer separation plate and the lower-layer separation plate are provided with through holes corresponding to the center pipe; the top of the outer sleeve I is connected with the middle-layer plate; the top of the outer sleeve II is connected with the lower-layer separation plate; the center pipe and the lower part of the outer sleeve II are connected through a connecting plate; agap is formed between the lower part of the outer sleeve I and the connecting plate; the water inlet pipe is arranged on the box, and communicates with a cavity formed between the middle-layer separation plate and the lower-layer separation plate; and the water outlet pipe is arranged on the box, and communicates with a cavity formed between the upper-layer separation plate and the middle-layer separation plate. Compared with similar equipment, the high-temperature coke powder cooling device is small in size and low in weight, improves the heat exchange efficiency by about 30%, and prolongs the service life by nearly one time.
Description
technical field [0001] The invention relates to the technical field of dry coke quenching, in particular to a high-temperature coke powder cooling device. Background technique [0002] The traditional CDQ high-temperature coke powder cooling device is a single-structure three-pipe, and its defects are as follows: 1) The effective heat exchange area per unit weight of the equipment is relatively small, and the distance between the high-temperature coke powder and the cooling water in the center is relatively large, which needs to be increased The cooling time needs to increase the heat exchange area to increase the volume of the equipment; 2) Due to its structural design defects, the internal water pipes are easily damaged. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the present invention is to provide a high-temperature coke powder cooling device to achieve the purpose of improving heat exc...
