Abstract
Description
Technical Field
[0001] This utility model relates to the field of camphor processing technology, and more specifically, to a camphor sublimation exhaust gas recovery device. Background Technology
[0002] Camphor requires sublimation purification during processing. In this process, crude camphor is first treated to remove oil and water, then placed in a sublimation kettle for melting and sublimation. Camphor vapor is introduced into the sublimation chamber along with blown air, and by controlling the cooling temperature, powdered camphor crystals are obtained. These finished products have high purity and meet the quality requirements of pharmacopoeias in various countries.
[0003] The sublimation and purification of camphor usually produces a large amount of exhaust gas, which contains some unsettled material. If the exhaust gas is not treated in time, it will not only pollute the environment, but also lead to resource waste and high production costs.
[0004] For example, a camphor sublimation tail gas recovery device with publication number CN213824122U uses a spray tower to spray the camphor sublimation tail gas. The sprayed water vapor then falls into a collection chamber for settling. A conveyor belt then uses a scraper to scrape off the camphor floating on the water surface, thus recovering the material from the tail gas. However, only natural camphor powder floats on the water surface, while most synthetic camphor powder sinks to the bottom. The aforementioned patent can only recover camphor floating on the water surface and cannot recover camphor that has sunk to the bottom, resulting in poor recovery efficiency. Utility Model Content
