Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection dust removal, in particular to a high-temperature sintered plate dust collector used in the lithium battery industry. Background Art

[0002] In recent years, with the increasing application of sintered plate dust collectors in the field of dust collection and purification, the lithium battery industry has begun to use sintered plate dust collectors to replace filter cartridges and bag-type dust collectors. Especially for some high temperature, high humidity and highly corrosive occasions, bag-type dust collectors are no longer applicable. Wet flue gas can easily clog the pores of the bags and increase the operating resistance. Due to the increase in the wear rate of the bags for some highly corrosive flue gases, the normal production operation of the system can no longer be maintained.

[0003] At present, sintered plate dust collectors have been widely used in the fields of lithium battery raw materials and process production, and their high dust removal efficiency has been confirmed. Due to the high temperature of flue gas (rotary kiln outlet flue gas), high moisture content, and strong corrosiveness, traditional filter cartridges and bag filters can easily penetrate and wear the filter element, resulting in a large amount of valuable resources being wasted and cannot be recycled. During equipment maintenance, the filter element needs to be frequently disassembled and replaced to maintain production. Therefore, due to the high temperature, high humidity and corrosiveness of flue gas, normal temperature sintered plate dust collectors are no longer applicable. After pre-treatment and cooling measures, the high temperature flue gas is reduced to an appropriate temperature range. The advantages of using high temperature sintered plate dust collectors are highlighted, and the problem of high temperature and high efficiency dust recovery is solved. Utility Model Content
