Gravity dust removal is a relatively old and simple dust removal method. The gravity sedimentation dust removal device is called gravity dust collector and also called sedimentation chamber.Its main advantages are: ① simple structure and easy maintenance; ② low resistance, generally about 5o ~ 15oPa, mainly due to pressure loss at the gas inlet and outlet; ③ maintenance Low cost and durability; ④ Excellent reliability and few failures. Its disadvantages are: ① low dust removal efficiency, generally only 40% ~ 5o%, suitable for trapping dust particles larger than 5oμm; ② large equipment, suitable for processing normal-temperature or high-temperature gas with medium air volume, mostly used as pre-dust for multi-stage dust removal use. Because of its unique advantages, it has applications in many occasions. When the amount of dust is large or the granularity is very small, it will be particularly advantageous to use a gravity dust collector to clean it in advance when it has a harmful effect on the next stage dust collector used in series.
There are many types of gravity dedusting equipment
and their forms are quite different, so there are many differences in structural performance. It is a kind of equipment that makes the particulate matter in the dust-containing gas settle naturally by the action of gravity.
