Graphite dust electrostatic dust collection system and method

Abstract

The invention discloses a graphite dust electrostatic dust collection system and method. The system comprises a telescopic material suction pipe, a storage tank, a cyclone dust collector, an air cooler, a first bag-type dust collector, a first roots fan and a first electrostatic dust collection device which are sequentially communicated through a pipeline. The system further comprises a second bag-type dust collector, a second roots fan and a second electrostatic dust collection device, wherein the second bag-type dust collector is communicated with the second roots fan through a pipeline. Thestorage tank comprises a telescopic discharging pipe arranged at the bottom, a dust-proof cover is arranged outside the telescopic discharge pipe, and an opening is formed in the dust-proof cover andcommunicated with the lower portion of the second bag-type dust collector through a pipeline. The double roots fan and the double bag-type dust collectors are switched to finish dust collection in the feeding and discharging process, the advanced dust collection system integrates dust pretreatment, cooling and purification, is reasonable in process design, scientific in structure, compact in arrangement, convenient to operate and maintain, high in dust collection efficiency and sufficiently meets purification and discharge requirements of high-pressure, high-temperature and high-concentrationdust.

Description

technical field [0001] The invention relates to the technical field of dust removal for tail gas purification treatment, in particular to an electrostatic dust removal system and method for graphite dust. Background technique [0002] In the lithium-ion battery anode material production workshop, it is necessary to crush, grind, and sort graphite and other materials; Grind to very fine; due to the limitations of equipment and technology, it is inevitable to produce a large amount of dust in actual operation. Because these dust particles are very fine, it is difficult to settle when floating in the production workshop, which not only pollutes the workshop environment, but also affects the health of the operators in the workshop. It also poses a great threat; traditional lithium-ion battery anode material production workshop dust collectors are mostly cloth bag type and dry powder rotary type, but for very small dust particles, they will escape from the bag and cannot be compl...

Problems solved by technology

[0002] In the lithium-ion battery anode material production workshop, it is necessary to crush, grind, and sort graphite and other materials; Grind to very fine; due to the limitations of equipment and technology, it is inevitable to produce a large amount of dust in actual operation. Because these dust particles are very fine, it is difficult to settle when floating in the production workshop, which not only pollutes the workshop environment, but also affects the health of the operators in the workshop. It also poses a great threat; traditional lithium-ion battery anode material production workshop dust collectors are mostly cloth bag type and dry powder rotary type, but for very small dust particles, they will escape from the bag and cannot be completely settled, and the dust removal effect is not ideal

[0003] In view of the characteristics of the above-mentioned flue gas, dust removal equipment is often used to achieve the purpose of dust removal, but this kind of dust removal equipment must meet the characteristics of high pressure resistance, effective cooling, multiple dust removal to ensure emission standards, etc., space is restricted, and the design must be compact and easy to operate. easy maintenance
