Ventilation device for storage of high-purity nano alumina

Abstract

The invention belongs to the technical field of chemical substance storage and discloses a ventilation device for storage of high-purity nano alumina. The ventilation device comprises a frame, one end of the frame is fixed together with a protection cover through bolts, a supporting frame is fixed inside the frame, a motor is fixed on the supporting frame, one end of the motor is connected with a fan blade through a rotating shaft, a sound absorbing structure is pasted on the inner surface layer of the frame, a first filtering layer is arranged at the other end of the frame, and a second filtering layer is arranged on one side of the first filtering layer. The first filtering layer can play a role in filtering impurities in air, and the ventilation device is convenient to demount and maintain.

Description

technical field [0001] The invention specifically relates to a ventilation device for high-purity nano-alumina preservation, which belongs to the technical field of chemical substance preservation. Background technique [0002] With the development of nanotechnology, alumina can be prepared into nanostructures with different shapes, such as nanowires, nanobelts, nanorods and whiskers, etc. These nanostructured aluminas have a large specific surface area. It has remarkable physical characteristics such as good hydrophobicity, good thermal and chemical stability, and excellent optical properties, so that alumina has very broad application prospects in the field of catalytic loading. When nano-alumina is stored, the storage environment has a certain impact on the quality of the product, so it is very important to maintain indoor ventilation during storage, and the existing ventilation is to send enough air into the indoor space by mechanical or natural methods. Fresh air, at t...

Problems solved by technology

When nano-alumina is stored, the storage environment has a certain impact on the quality of the product, so it is very important to maintain indoor ventilation during storage, and the existing ventilation is to send enough air into the indoor space by mechanical or natural methods. Fresh air, at the same time discharge the indoor dirty air that does not meet the hygienic requirements, so that the indoor air meets the hygienic requirements and the needs of preservation. However, when the existing ventilation equipment is in use, it often produces a lot of noise and does not have the ability to purify the air. Effect
