Graphite powder disposal and recovery system and method based on double switches

Abstract

The invention discloses a graphite powder disposal and recovery system and method based on double switches. The system includes a retractable material sucking pipe, a storage tank, a cyclone dust collector, an air cooler, a cloth bag dust collector, a Roots blower and a recovery device which are communicated with one another through pipes in sequence; the Roots blower is used for providing power for conveying graphite powder, and the graphite powder is conveyed by means of negative-pressure air generated by the Roots blower; the system further includes a first switch device and a second switchdevice, the first switch device is arranged on the pipe by means of which the air cooler is communicated with the cloth bag dust collector, and the second switch device is arranged on the pipe by means of which a retractable material discharging pipe is communicated with the bottom of the cloth bag dust collector. Through the two switch devices, dedusting during material conveying and dischargingis switched, and the system is an advanced dedusting system integrating dust pretreatment, cooling, tail gas purification and flexible control; the process design is reasonable, the structure is scientific, the layout is compact, operating maintenance is convenient, the dedusting efficiency is high, and purified emission of high-pressure, high-temperature and high-concentration dust is fully achieved.

Description

technical field [0001] The invention relates to the technical field of dust removal for tail gas purification treatment, in particular to a graphite dust treatment and recovery system and method based on a double switch. 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...

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
