Abstract
Description
Technical Field
[0001] The utility model belongs to the field of kiln flues, and in particular relates to a kiln flue damper structure. Background Art
[0002] The kiln flue damper is an important component in the kiln system for controlling the flow of the flue. It is usually installed at the flue of the kiln and regulates the flow of flue gas by opening or closing.
[0003] However, current kiln flue dampers typically only have an open or closed function, making them inconvenient to adjust flexibly. This lack of flexible adjustment to the flue gas filtration state seriously affects environmental protection. During the flue gas exhaust process at different production stages, the flue gas may contain particulate impurities at certain times. If the damper is not adjusted to the filtering state according to actual conditions, these harmful impurities will be directly discharged into the atmosphere, causing serious environmental pollution. Currently, this single-function damper cannot meet environmental protection requirements. In addition, the flow rate and composition of the flue gas will vary depending on the production stage and operating conditions. Failure to adjust the damper to the appropriate operating state may cause flue duct blockage, abnormal pressure, and other problems, affecting the normal operation of the kiln.
[0004] In view of this, we proposed a kiln flue damper structure that can be flexibly switched. Utility Model Content
