Graphite dust electrostatic dedusting method based on two switches

Abstract

The invention discloses a graphite dust electrostatic dedusting method based on two switches. The graphite dust electrostatic dedusting method based on two switches comprises a blower fan unit, a switch device 1, and a switch device 2; the blower fan unit is used for providing conveying power, high temperature graphite powder is delivered through a material storage unit, a pre-dedusting unit, a cooling unit, and a dedusting unit by generated negative pressure air flow successively; the switch device 1 is arranged between the cooling unit and the dedusting unit; the switch device 2 is arrangedbetween the material storage unit and the dedusting unit. In applications, the open and close states of the switch device 1 and the switch device 2 is switched to complete graphite powder feeding anddischarging, and two dedusting processes; and the open and close states of the switch device 1 is designed to be opposite to the open and close states of the switch device 2. According to the graphitedust electrostatic dedusting method, an advanced dedusting system capable of realizing dust pretreatment, cooling, tail gas purification, and flexible control is formed through two switch device switched feeding and discharging; process design is reasonable; the structure is scientific and compact; operation and maintenance are convenient; dedusting efficiency is high; and high pressure, high temperature, high concentration dust purifying discharging requirements are satisfied.

Description

technical field [0001] The invention relates to the technical field of dust removal for tail gas purification treatment, in particular to a method for electrostatic dust removal of graphite dust 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
