Description

Technical Field

[0001] The utility model relates to the technical field of a fume heat exchanger for a calcium carbide furnace, in particular to a fume heat exchanger for a calcium carbide furnace. Background Art

[0002] During the production process of the calcium carbide furnace, due to factors such as material collapse and poor sealing, a large amount of dust will be generated and accumulated on the second floor of the calcium carbide furnace. In order to prevent dust accumulation, a calcium carbide furnace flue gas heat exchanger is often used.

[0003] During the use of the existing calcium carbide furnace flue gas heat exchanger, the flue gas is generally processed by a dust collector, then enters the heat exchanger through the heat exchanger inlet for circulation, and is finally discharged from the heat exchanger outlet. Dust will accumulate in the long-term circulation of the flue gas in the heat exchanger, and the dust can be checked through the fire detection hole. If there is too much dust, remove the manhole cover for manual cleaning. The dust will fall into the dust bin below after manual cleaning, and the sealed unloading valve is opened to discharge through the scraper conveyor. Although the existing technology can complete the dust cleaning work during use to avoid interference with normal heat exchange, it is necessary to first remove the manhole cover and then perform manual cleaning, which has the problem of cumbersome operation, and the calcium carbide furnace flue gas converter needs to be closed during the cleaning process, resulting in prolonged working time and reduced operating efficiency. Therefore, we urgently need to improve the calcium carbide furnace flue gas heat exchanger to solve the above problems. Utility Model Content
