Description

Technical Field

[0001] This invention relates to the field of dust removal technology, specifically a limestone feeding dust removal system. Background Technology

[0002] Limestone, also known as limestone, is a carbonate rock primarily composed of calcite. It sometimes contains dolomite, clay minerals, and detrital minerals. It comes in various colors including gray, grayish-white, grayish-black, yellow, light red, and brownish-red. It is generally not very hard and reacts violently with dilute hydrochloric acid. Classified by its formation, it belongs to sedimentary rocks. The feeding of limestone generates a large amount of dust, necessitating dust removal to extract particulate matter from the dust-laden gas and reduce its emission into the atmosphere. If a baghouse dust collector system is used, the filter bags must be replaced regularly, and there are specific requirements regarding the dust collection temperature range.
