Description

Technical Field

[0001] The utility model relates to the technical field of ash coolers, in particular to a vertical cooling ash cooler. Background Art

[0002] Ash cooler is a device for collecting and conveying ash, mainly used for ash treatment in power station boilers and industrial furnaces. Its basic principle is to use a fan to convey ash from the boiler to the cooling area, and then transport it to the treatment area by a conveyor belt after cooling. This equipment needs to collect ash from the boiler and then convey it to a suitable place for treatment, which can effectively reduce the adverse effects of ash on the environment and equipment, and ensure the safety and hygiene of the production environment.

[0003] According to the prior art, publication number CN105605948A discloses a high-temperature dry ash cooler, which includes a cooling body, wherein the cooling body is provided with a feeding chamber and a cooling chamber arranged outside the feeding chamber, wherein a feeding mechanism is arranged in the feeding chamber; a feeding port is arranged at one end of the feeding chamber, and a discharge port is arranged at the other end of the feeding chamber; a first water inlet is arranged at one end of the cooling chamber, and a first water outlet is arranged at the other end of the cooling chamber; and a driving device for driving the feeding mechanism is also included.

[0004] In the reference document, the high-temperature dry ash after cooling can be directly piled up in a centralized manner without the need to distribute the heat dissipation, thus saving land. Moreover, when the cooler realizes high-temperature cooling, the cooling water can also be used for heat energy recovery. However, the cooler itself is set horizontally, which occupies a large area and affects the layout of other equipment. Utility Model Content
