Problems solved by technology

For example, in the graphite powder production workshop, black and fine graphite powder is often dispersed in the air. Inhalation into the lungs through the nostrils affects the health of the operator. Some microparticles are relatively valuable resources. Therefore, the microparticles dispersed in the air not only pollute the environment, affect human health, but also waste resources.
The collection of these microparticles is very important and necessary, but so far there is no cost-effective, high-purity method for collecting microparticles

Embodiment Construction

[0011] In this embodiment, taking graphite collection as an example, the present invention will be further described in conjunction with the accompanying drawings.

[0012] figure 1 It is a structural schematic diagram of a microparticle collection device for implementing the present invention, figure 2 A schematic diagram of the structure of the microparticle collector is given, which is a published patent technology that the inventor participated in the design (patent number is: ZL90214370.0, the name is: a particle dust collector, announcement date: 1991 On May 8, 2010), the inventor cleverly used this technology as a microparticle collector to achieve the purpose of collecting graphite substances with high purity.

[0013] The air containing graphite microparticles is continuously sucked into the air inlet pipe 2 by the air inlet 1 under the action of the induced draft fan 7, and enters the cyclone 14 in the microparticle collector 3 along the air inlet pipe 2. The shape...

Abstract

A process for collecting microparticles from air includes such steps as sucking the air containing microparticles into cyclone barrel, and filtering by filter material layer for separating air from microparticles. Said filter material layer is composed of filter net and said microparticles as filter material spread on said filter net. Its advantages are high purity and low cost.

Description

technical field [0001] The invention relates to a method for collecting microparticles, in particular to a method for collecting microparticles in air with high purity. Background technique [0002] In the chemical industry, metallurgy, mining and other industries, some substances are often transformed into fine particles due to the production and processing process, which are distributed and floated in the air. For example, in the graphite powder production workshop, black and fine graphite powder is often dispersed in the air. Inhalation into the lungs through the nostrils affects the health of the operator. Some microparticles are relatively valuable resources. Therefore, those microparticles dispersed in the air not only pollute the environment, affect human health, but also waste resources. The collection of these microparticles is very important and necessary, but so far there is no cost-effective, high-purity method for collecting microparticles. Contents of the in...
