Abstract
Description
Technical Field
[0001] This utility model relates to the field of calcium carbide furnaces, and in particular to a purified gas ash conveying system. Background Technology
[0002] The normal temperature of the flue gas produced by the closed calcium carbide furnace is below 900℃. After passing through the water-cooled flue and settling tank, the flue gas temperature is controlled between 180℃ and 260℃. The flue gas is pressurized by a rough air blower and drawn into the purification system. At this time, some of the flue gas will adhere to the wall of the purification flue. Over time, hard clumps of about 5-8cm will accumulate, causing the blower frequency in the purification system to increase. Therefore, the flue must be cleaned after a period of operation. The cleaned clumps will fall into the gravity bin and then be transported to the gas ash conveying system by a scraper conveyor. However, if the clumps in the flue are too large or too numerous, the gas ash conveying system will be difficult to operate normally, often resulting in blockages and reducing the gas ash conveying efficiency. At the same time, workers face the risks of poisoning and falls from heights when clearing the gas ash conveying system, increasing the labor intensity of the workers. Utility Model Content
