Graphite electrostatic dust collection system based on multiple switches and method

Abstract

The invention discloses a graphite electrostatic dust collection system based on multiple switches and a method. The system comprises a telescopic sucking tube, a storage tank, a cyclone dust collector, an air cooler, a cloth bag dust collector, a first Roots blower, a first electrostatic dust collection device as well as a second Roots blower, a second electrostatic dust collection device, a switch device I, a switch device II, a switch device III and a switch device IV, wherein the telescopic sucking tube, the storage tank, the cyclone dust collector, the air cooler, the cloth bag dust collector, the first Roots blower and the first electrostatic dust collection device are communicated in sequence through pipelines; the switch device I is arranged on a pipeline for communicating the aircooler with the cloth bag dust collector; the switch device II is arranged on a pipeline for communicating the telescopic sucking tube with the bottom of the cloth bag dust collector; the switch device III is arranged on a pipeline for communicating the first Roots blower with the cloth bag dust collector; the switch device IV is arranged on a pipeline for communicating the second Roots blower with the cloth bag dust collector. Through switching of multiple switch devices, functions of dust treatment, cooling, purification and flexible control are integrated, the system is compact in arrangement, convenient to operate and repair and high in dust collection efficiency, and requirement on purification discharge of high-pressure high-temperature high-concentration dust is sufficiently met.

Description

technical field

[0001] The invention relates to the technical field of dust removal for tail gas purification treatment, in particular to a multi-switch based 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 a...
