Zinc oxide dust removal device

Abstract

The invention discloses a zinc oxide dust removal device. The device comprises a shell, a crushing assembly and a dust removal assembly. The shell comprises a feeding cavity and a dust removal cavity connected to the lower portion of the feeding cavity. The crushing assembly is arranged in the feeding cavity and comprises a crushing roller. The dust removal assembly is detachably installed in the dust removal cavity and comprises a dust adsorption element and a zinc oxide crushed aggregate screening device. The zinc oxide dust removal device is simple and reasonable in structure, dust generated in the falling process of zinc oxide crushed aggregates from top to bottom is adsorbed to an adsorption filter membrane through negative pressure, and meanwhile low-temperature mist is sprayed to the adsorption filter membrane through a cooling water spraying device; and the adsorbed dust is deposited on the surface of the adsorption filter membrane under the action of a low-temperature and low-humidity environment and cannot penetrate through the filter membrane to diffuse to a third space and a second space, the cleanliness of other equipment can be effectively guaranteed, the adsorption filter membrane can be effectively prevented from being blocked for a long time in cooperation with timely flushing of a backwashing device, cleaning is convenient, and therefore, the working efficiency of the dust removal equipment is greatly improved, and the service life of the dust removal equipment is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of industrial solid waste, and relates to a dust removal device, in particular to a zinc oxide dust removal device. Background technique [0002] Zinc oxide is a commonly used chemical additive, widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paint coatings, ointments, adhesives, food, batteries, flame retardants and other products. As an oxide, zinc oxide is insoluble in water but soluble in acid and strong alkali. Zinc oxide produces a lot of dust during production, which will cause air pollution if left untreated. Therefore, it is necessary to collect the dust produced during production. [0003] However, the existing zinc oxide dust removal equipment mostly adopts structures such as dust removal tanks or filter bags for particle adsorption and collection, which is not only complex in structure, redundant in design, but also inconve...

Problems solved by technology

[0003] However, the existing zinc oxide dust removal equipment mostly adopts structures such as dust removal tanks or filter bags for particle adsorption and collection, which is not only complex in structure, redundant in design, but also inconvenient to clean. However, long-term operation will cause problems such as clogging of filter elements, which It will greatly reduce the working efficiency of the dust removal equipment, and will increase the repair and maintenance costs
